+  \brief The abstract base class for paint buffers, which define the rendering backend
+
+  This abstract base class defines the basic interface that a paint buffer needs to provide in
+  order to be usable by QCustomPlot.
+
+  A paint buffer manages both a surface to draw onto, and the matching paint device. The size of
+  the surface can be changed via \ref setSize. External classes (\ref QCustomPlot and \ref
+  QCPLayer) request a painter via \ref startPainting and then perform the draw calls. Once the
+  painting is complete, \ref donePainting is called, so the paint buffer implementation can do
+  clean up if necessary. Before rendering a frame, each paint buffer is usually filled with a color
+  using \ref clear (usually the color is \c Qt::transparent), to remove the contents of the
+  previous frame.
+
+  The simplest paint buffer implementation is \ref QCPPaintBufferPixmap which allows regular
+  software rendering via the raster engine. Hardware accelerated rendering via pixel buffers and
+  frame buffer objects is provided by \ref QCPPaintBufferGlPbuffer and \ref QCPPaintBufferGlFbo.

+  bottom to top and successively draws the layerables of the layers into the paint buffer(s).
+
+  A QCPLayer contains an ordered list of QCPLayerable instances. QCPLayerable is an abstract base
+  class from which almost all visible objects derive, like axes, grids, graphs, items, etc.
+
+  \section qcplayer-defaultlayers Default layers
+
+  Initially, QCustomPlot has six layers: "background", "grid", "main", "axes", "legend" and
+  "overlay" (in that order). On top is the "overlay" layer, which only contains the QCustomPlot's
+  selection rect (\ref QCustomPlot::selectionRect). The next two layers "axes" and "legend" contain
+  the default axes and legend, so they will be drawn above plottables. In the middle, there is the
+  "main" layer. It is initially empty and set as the current layer (see
+  QCustomPlot::setCurrentLayer). This means, all new plottables, items etc. are created on this
+  layer by default. Then comes the "grid" layer which contains the QCPGrid instances (which belong
+  tightly to QCPAxis, see \ref QCPAxis::grid). The Axis rect background shall be drawn behind
+  everything else, thus the default QCPAxisRect instance is placed on the "background" layer. Of
+  course, the layer affiliation of the individual objects can be changed as required (\ref
+  QCPLayerable::setLayer).
+
+  \section qcplayer-ordering Controlling the rendering order via layers
+
+  Controlling the ordering of layerables in the plot is easy: Create a new layer in the position
+  you want the layerable to be in, e.g. above "main", with \ref QCustomPlot::addLayer. Then set the
+  current layer with \ref QCustomPlot::setCurrentLayer to that new layer and finally create the
+  objects normally. They will be placed on the new layer automatically, due to the current layer
+  setting. Alternatively you could have also ignored the current layer setting and just moved the
+  objects with \ref QCPLayerable::setLayer to the desired layer after creating them.
+
+  It is also possible to move whole layers. For example, If you want the grid to be shown in front
+  of all plottables/items on the "main" layer, just move it above "main" with
+  QCustomPlot::moveLayer.
+
+  The rendering order within one layer is simply by order of creation or insertion. The item
+  created last (or added last to the layer), is drawn on top of all other objects on that layer.
+
+  When a layer is deleted, the objects on it are not deleted with it, but fall on the layer below
+  the deleted layer, see QCustomPlot::removeLayer.
+
+  \section qcplayer-buffering Replotting only a specific layer
+
+  If the layer mode (\ref setMode) is set to \ref lmBuffered, you can replot only this specific
+  layer by calling \ref replot. In certain situations this can provide better replot performance,
+  compared with a full replot of all layers. Upon creation of a new layer, the layer mode is
+  initialized to \ref lmLogical. The only layer that is set to \ref lmBuffered in a new \ref
+  QCustomPlot instance is the "overlay" layer, containing the selection rect.

+  \internal
+  
+  This function applies the default antialiasing setting to the specified \a painter, using the
+  function \ref applyAntialiasingHint. It is the antialiasing state the painter is put in, when
+  \ref draw is called on the layerable. If the layerable has multiple entities whose antialiasing
+  setting may be specified individually, this function should set the antialiasing state of the
+  most prominent entity. In this case however, the \ref draw function usually calls the specialized
+  versions of this function before drawing each entity, effectively overriding the setting of the
+  default antialiasing hint.
+  
+  <b>First example:</b> QCPGraph has multiple entities that have an antialiasing setting: The graph
+  line, fills and scatters. Those can be configured via QCPGraph::setAntialiased,
+  QCPGraph::setAntialiasedFill and QCPGraph::setAntialiasedScatters. Consequently, there isn't only
+  the QCPGraph::applyDefaultAntialiasingHint function (which corresponds to the graph line's
+  antialiasing), but specialized ones like QCPGraph::applyFillAntialiasingHint and
+  QCPGraph::applyScattersAntialiasingHint. So before drawing one of those entities, QCPGraph::draw
+  calls the respective specialized applyAntialiasingHint function.
+  
+  <b>Second example:</b> QCPItemLine consists only of a line so there is only one antialiasing
+  setting which can be controlled with QCPItemLine::setAntialiased. (This function is inherited by
+  all layerables. The specialized functions, as seen on QCPGraph, must be added explicitly to the
+  respective layerable subclass.) Consequently it only has the normal
+  QCPItemLine::applyDefaultAntialiasingHint. The \ref QCPItemLine::draw function doesn't need to
+  care about setting any antialiasing states, because the default antialiasing hint is already set
+  on the painter when the \ref draw function is called, and that's the state it wants to draw the

+  the data range, similarly to the nomenclature used in standard iterators.
+  
+  Data Ranges are not bound to a certain plottable, thus they can be freely exchanged, created and
+  modified. If a non-contiguous data set shall be described, the class \ref QCPDataSelection is

+  QCPDataSelection is thus used.

+  Both \ref QCPDataRange and \ref QCPDataSelection offer convenience methods to work with them,
+  e.g. \ref bounded, \ref expanded, \ref intersects, \ref intersection, \ref adjusted, \ref
+  contains. Further, addition and subtraction operators (defined in \ref QCPDataSelection) can be
+  used to join/subtract data ranges and data selections (or mixtures), to retrieve a corresponding
+  \ref QCPDataSelection.
+  
+  %QCustomPlot's \ref dataselection "data selection mechanism" is based on \ref QCPDataSelection and
+  QCPDataRange.

+/*! \class QCPDataSelection
+  \brief Describes a data set by holding multiple QCPDataRange instances
+  
+  QCPDataSelection manages multiple instances of QCPDataRange in order to represent any (possibly
+  disjoint) set of data selection.
+  
+  The data selection can be modified with addition and subtraction operators which take
+  QCPDataSelection and QCPDataRange instances, as well as methods such as \ref addDataRange and
+  \ref clear. Read access is provided by \ref dataRange, \ref dataRanges, \ref dataRangeCount, etc.
+  
+  The method \ref simplify is used to join directly adjacent or even overlapping QCPDataRange
+  instances. QCPDataSelection automatically simplifies when using the addition/subtraction
+  operators. The only case when \ref simplify is left to the user, is when calling \ref
+  addDataRange, with the parameter \a simplify explicitly set to false. This is useful if many data
+  ranges will be added to the selection successively and the overhead for simplifying after each
+  iteration shall be avoided. In this case, you should make sure to call \ref simplify after
+  completing the operation.
+  
+  Use \ref enforceType to bring the data selection into a state complying with the constraints for
+  selections defined in \ref QCP::SelectionType.
+  
+  %QCustomPlot's \ref dataselection "data selection mechanism" is based on QCPDataSelection and
+  QCPDataRange.
+

+/*! \class QCPMarginGroup
+  \brief A margin group allows synchronization of margin sides if working with multiple layout elements.
+  
+  QCPMarginGroup allows you to tie a margin side of two or more layout elements together, such that
+  they will all have the same size, based on the largest required margin in the group.
+  
+  \n
+  \image html QCPMarginGroup.png "Demonstration of QCPMarginGroup"
+  \n
+  
+  In certain situations it is desirable that margins at specific sides are synchronized across
+  layout elements. For example, if one QCPAxisRect is below another one in a grid layout, it will
+  provide a cleaner look to the user if the left and right margins of the two axis rects are of the
+  same size. The left axis of the top axis rect will then be at the same horizontal position as the
+  left axis of the lower axis rect, making them appear aligned. The same applies for the right
+  axes. This is what QCPMarginGroup makes possible.
+  
+  To add/remove a specific side of a layout element to/from a margin group, use the \ref
+  QCPLayoutElement::setMarginGroup method. To completely break apart the margin group, either call
+  \ref clear, or just delete the margin group.
+  
+  \section QCPMarginGroup-example Example
+  
+  First create a margin group:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpmargingroup-creation-1
+  Then set this group on the layout element sides:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpmargingroup-creation-2
+  Here, we've used the first two axis rects of the plot and synchronized their left margins with
+  each other and their right margins with each other.

+  \brief The abstract base class for all objects that form \ref thelayoutsystem "the layout system".
+  
+  This is an abstract base class. As such, it can't be instantiated directly, rather use one of its subclasses.
+  
+  A Layout element is a rectangular object which can be placed in layouts. It has an outer rect
+  (QCPLayoutElement::outerRect) and an inner rect (\ref QCPLayoutElement::rect). The difference
+  between outer and inner rect is called its margin. The margin can either be set to automatic or
+  manual (\ref setAutoMargins) on a per-side basis. If a side is set to manual, that margin can be
+  set explicitly with \ref setMargins and will stay fixed at that value. If it's set to automatic,
+  the layout element subclass will control the value itself (via \ref calculateAutoMargin).
+  
+  Layout elements can be placed in layouts (base class QCPLayout) like QCPLayoutGrid. The top level
+  layout is reachable via \ref QCustomPlot::plotLayout, and is a \ref QCPLayoutGrid. Since \ref
+  QCPLayout itself derives from \ref QCPLayoutElement, layouts can be nested.
+  
+  Thus in QCustomPlot one can divide layout elements into two categories: The ones that are
+  invisible by themselves, because they don't draw anything. Their only purpose is to manage the
+  position and size of other layout elements. This category of layout elements usually use
+  QCPLayout as base class. Then there is the category of layout elements which actually draw
+  something. For example, QCPAxisRect, QCPLegend and QCPTextElement are of this category. This does
+  not necessarily mean that the latter category can't have child layout elements. QCPLegend for
+  instance, actually derives from QCPLayoutGrid and the individual legend items are child layout
+  elements in the grid layout.

+  (but there are exceptions to this, e.g. QCPLegend).
+  
+  QCPLayout derives from QCPLayoutElement, and thus can itself be nested in other layouts.
+  
+  QCPLayout introduces a common interface for accessing and manipulating the child elements. Those
+  functions are most notably \ref elementCount, \ref elementAt, \ref takeAt, \ref take, \ref
+  simplify, \ref removeAt, \ref remove and \ref clear. Individual subclasses may add more functions
+  to this interface which are more specialized to the form of the layout. For example, \ref
+  QCPLayoutGrid adds functions that take row and column indices to access cells of the layout grid
+  more conveniently.
+  
+  Since this is an abstract base class, you can't instantiate it directly. Rather use one of its
+  subclasses like QCPLayoutGrid or QCPLayoutInset.
+  
+  For a general introduction to the layout system, see the dedicated documentation page \ref
+  thelayoutsystem "The Layout System".

+/*! \class QCPAxisTicker
+  \brief The base class tick generator used by QCPAxis to create tick positions and tick labels
+  
+  Each QCPAxis has an internal QCPAxisTicker (or a subclass) in order to generate tick positions
+  and tick labels for the current axis range. The ticker of an axis can be set via \ref
+  QCPAxis::setTicker. Since that method takes a <tt>QSharedPointer<QCPAxisTicker></tt>, multiple
+  axes can share the same ticker instance.
+  
+  This base class generates normal tick coordinates and numeric labels for linear axes. It picks a
+  reasonable tick step (the separation between ticks) which results in readable tick labels. The
+  number of ticks that should be approximately generated can be set via \ref setTickCount.
+  Depending on the current tick step strategy (\ref setTickStepStrategy), the algorithm either
+  sacrifices readability to better match the specified tick count (\ref
+  QCPAxisTicker::tssMeetTickCount) or relaxes the tick count in favor of better tick steps (\ref
+  QCPAxisTicker::tssReadability), which is the default.
+  
+  The following more specialized axis ticker subclasses are available, see details in the
+  respective class documentation:

+  \section axisticker-subclassing Creating own axis tickers
+  
+  Creating own axis tickers can be achieved very easily by sublassing QCPAxisTicker and
+  reimplementing some or all of the available virtual methods.
+
+  In the simplest case you might wish to just generate different tick steps than the other tickers,
+  so you only reimplement the method \ref getTickStep. If you additionally want control over the
+  string that will be shown as tick label, reimplement \ref getTickLabel.
+  
+  If you wish to have complete control, you can generate the tick vectors and tick label vectors
+  yourself by reimplementing \ref createTickVector and \ref createLabelVector. The default
+  implementations use the previously mentioned virtual methods \ref getTickStep and \ref
+  getTickLabel, but your reimplementations don't necessarily need to do so. For example in the case
+  of unequal tick steps, the method \ref getTickStep loses its usefulness and can be ignored.
+  
+  The sub tick count between major ticks can be controlled with \ref getSubTickCount. Full sub tick
+  placement control is obtained by reimplementing \ref createSubTickVector.
+  
+  See the documentation of all these virtual methods in QCPAxisTicker for detailed information
+  about the parameters and expected return values.

+/*! \class QCPAxisTickerDateTime
+  \brief Specialized axis ticker for calendar dates and times as axis ticks
+  
+  \image html axisticker-datetime.png
+  
+  This QCPAxisTicker subclass generates ticks that correspond to real calendar dates and times. The
+  plot axis coordinate is interpreted as Unix Time, so seconds since Epoch (January 1, 1970, 00:00
+  UTC). This is also used for example by QDateTime in the <tt>toTime_t()/setTime_t()</tt> methods
+  with a precision of one second. Since Qt 4.7, millisecond accuracy can be obtained from QDateTime
+  by using <tt>QDateTime::fromMSecsSinceEpoch()/1000.0</tt>. The static methods \ref dateTimeToKey
+  and \ref keyToDateTime conveniently perform this conversion achieving a precision of one
+  millisecond on all Qt versions.
+  
+  The format of the date/time display in the tick labels is controlled with \ref setDateTimeFormat.
+  If a different time spec (time zone) shall be used, see \ref setDateTimeSpec.
+  
+  This ticker produces unequal tick spacing in order to provide intuitive date and time-of-day
+  ticks. For example, if the axis range spans a few years such that there is one tick per year,
+  ticks will be positioned on 1. January of every year. This is intuitive but, due to leap years,
+  will result in slightly unequal tick intervals (visually unnoticeable). The same can be seen in
+  the image above: even though the number of days varies month by month, this ticker generates
+  ticks on the same day of each month.
+  
+  If you would like to change the date/time that is used as a (mathematical) starting date for the
+  ticks, use the \ref setTickOrigin(const QDateTime &origin) method overload, which takes a
+  QDateTime. If you pass 15. July, 9:45 to this method, the yearly ticks will end up on 15. July at
+  9:45 of every year.
+  
+  The ticker can be created and assigned to an axis like this:
+  \snippet documentation/doc-image-generator/mainwindow.cpp axistickerdatetime-creation
+  
+  \note If you rather wish to display relative times in terms of days, hours, minutes, seconds and

+/*! \class QCPAxisTickerTime
+  \brief Specialized axis ticker for time spans in units of milliseconds to days
+  
+  \image html axisticker-time.png
+  
+  This QCPAxisTicker subclass generates ticks that corresponds to time intervals.
+  
+  The format of the time display in the tick labels is controlled with \ref setTimeFormat and \ref
+  setFieldWidth. The time coordinate is in the unit of seconds with respect to the time coordinate
+  zero. Unlike with QCPAxisTickerDateTime, the ticks don't correspond to a specific calendar date
+  and time.
+  
+  The time can be displayed in milliseconds, seconds, minutes, hours and days. Depending on the
+  largest available unit in the format specified with \ref setTimeFormat, any time spans above will
+  be carried in that largest unit. So for example if the format string is "%m:%s" and a tick at
+  coordinate value 7815 (being 2 hours, 10 minutes and 15 seconds) is created, the resulting tick
+  label will show "130:15" (130 minutes, 15 seconds). If the format string is "%h:%m:%s", the hour
+  unit will be used and the label will thus be "02:10:15". Negative times with respect to the axis
+  zero will carry a leading minus sign.
+  
+  The ticker can be created and assigned to an axis like this:
+  \snippet documentation/doc-image-generator/mainwindow.cpp axistickertime-creation
+  
+  Here is an example of a time axis providing time information in days, hours and minutes. Due to
+  the axis range spanning a few days and the wanted tick count (\ref setTickCount), the ticker
+  decided to use tick steps of 12 hours:
+  
+  \image html axisticker-time2.png
+  
+  The format string for this example is
+  \snippet documentation/doc-image-generator/mainwindow.cpp axistickertime-creation-2

+  \note If you rather wish to display calendar dates and times, have a look at QCPAxisTickerDateTime

+/*! \class QCPGrid
+  \brief Responsible for drawing the grid of a QCPAxis.
+  
+  This class is tightly bound to QCPAxis. Every axis owns a grid instance and uses it to draw the
+  grid lines, sub grid lines and zero-line. You can interact with the grid of an axis via \ref
+  QCPAxis::grid. Normally, you don't need to create an instance of QCPGrid yourself.
+  
+  The axis and grid drawing was split into two classes to allow them to be placed on different
+  layers (both QCPAxis and QCPGrid inherit from QCPLayerable). Thus it is possible to have the grid
+  in the background and the axes in the foreground, and any plottables/items in between. This
+  described situation is the default setup, see the QCPLayer documentation.

+  
+  \a formatCode is a string of one, two or three characters. The first character is identical to

+  format, 'g'/'G' scientific or fixed, whichever is shorter.
+  
+  The second and third characters are optional and specific to QCustomPlot:\n
+  If the first char was 'e' or 'g', numbers are/might be displayed in the scientific format, e.g.
+  "5.5e9", which is ugly in a plot. So when the second char of \a formatCode is set to 'b' (for
+  "beautiful"), those exponential numbers are formatted in a more natural way, i.e. "5.5
+  [multiplication sign] 10 [superscript] 9". By default, the multiplication sign is a centered dot.
+  If instead a cross should be shown (as is usual in the USA), the third char of \a formatCode can
+  be set to 'c'. The inserted multiplication signs are the UTF-8 characters 215 (0xD7) for the
+  cross and 183 (0xB7) for the dot.
+  
+  Examples for \a formatCode:
+  \li \c g normal format code behaviour. If number is small, fixed format is used, if number is large,
+  normal scientific format is used
+  \li \c gb If number is small, fixed format is used, if number is large, scientific format is used with
+  beautifully typeset decimal powers and a dot as multiplication sign
+  \li \c ebc All numbers are in scientific format with beautifully typeset decimal power and a cross as
+  multiplication sign
+  \li \c fb illegal format code, since fixed format doesn't support (or need) beautifully typeset decimal
+  powers. Format code will be reduced to 'f'.
+  \li \c hello illegal format code, since first char is not 'e', 'E', 'f', 'g' or 'G'. Current format

+
+/*! \class QCPScatterStyle
+  \brief Represents the visual appearance of scatter points
+  
+  This class holds information about shape, color and size of scatter points. In plottables like
+  QCPGraph it is used to store how scatter points shall be drawn. For example, \ref
+  QCPGraph::setScatterStyle takes a QCPScatterStyle instance.
+  
+  A scatter style consists of a shape (\ref setShape), a line color (\ref setPen) and possibly a
+  fill (\ref setBrush), if the shape provides a fillable area. Further, the size of the shape can
+  be controlled with \ref setSize.
+
+  \section QCPScatterStyle-defining Specifying a scatter style
+  
+  You can set all these configurations either by calling the respective functions on an instance:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpscatterstyle-creation-1
+  
+  Or you can use one of the various constructors that take different parameter combinations, making
+  it easy to specify a scatter style in a single call, like so:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpscatterstyle-creation-2
+  
+  \section QCPScatterStyle-undefinedpen Leaving the color/pen up to the plottable
+  
+  There are two constructors which leave the pen undefined: \ref QCPScatterStyle() and \ref
+  QCPScatterStyle(ScatterShape shape, double size). If those constructors are used, a call to \ref
+  isPenDefined will return false. It leads to scatter points that inherit the pen from the
+  plottable that uses the scatter style. Thus, if such a scatter style is passed to QCPGraph, the line
+  color of the graph (\ref QCPGraph::setPen) will be used by the scatter points. This makes
+  it very convenient to set up typical scatter settings:
+  
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpscatterstyle-shortcreation
+
+  Notice that it wasn't even necessary to explicitly call a QCPScatterStyle constructor. This works
+  because QCPScatterStyle provides a constructor that can transform a \ref ScatterShape directly
+  into a QCPScatterStyle instance (that's the \ref QCPScatterStyle(ScatterShape shape, double size)
+  constructor with a default for \a size). In those cases, C++ allows directly supplying a \ref
+  ScatterShape, where actually a QCPScatterStyle is expected.
+  
+  \section QCPScatterStyle-custompath-and-pixmap Custom shapes and pixmaps
+  
+  QCPScatterStyle supports drawing custom shapes and arbitrary pixmaps as scatter points.
+
+  For custom shapes, you can provide a QPainterPath with the desired shape to the \ref
+  setCustomPath function or call the constructor that takes a painter path. The scatter shape will
+  automatically be set to \ref ssCustom.
+  
+  For pixmaps, you call \ref setPixmap with the desired QPixmap. Alternatively you can use the
+  constructor that takes a QPixmap. The scatter shape will automatically be set to \ref ssPixmap.
+  Note that \ref setSize does not influence the appearance of the pixmap.

+  is undefined, the pen of the respective plottable will be used for drawing scatters.

+  \brief Controls how a plottable's data selection is drawn
+  
+  Each \ref QCPAbstractPlottable instance has one \ref QCPSelectionDecorator (accessible via \ref
+  QCPAbstractPlottable::selectionDecorator) and uses it when drawing selected segments of its data.
+  
+  The selection decorator controls both pen (\ref setPen) and brush (\ref setBrush), as well as the
+  scatter style (\ref setScatterStyle) if the plottable draws scatters. Since a \ref
+  QCPScatterStyle is itself composed of different properties such as color shape and size, the
+  decorator allows specifying exactly which of those properties shall be used for the selected data
+  point, via \ref setUsedScatterProperties.
+  
+  A \ref QCPSelectionDecorator subclass instance can be passed to a plottable via \ref
+  QCPAbstractPlottable::setSelectionDecorator, allowing greater customizability of the appearance
+  of selected segments.
+  
+  Use \ref copyFrom to easily transfer the settings of one decorator to another one. This is
+  especially useful since plottables take ownership of the passed selection decorator, and thus the
+  same decorator instance can not be passed to multiple plottables.
+  
+  Selection decorators can also themselves perform drawing operations by reimplementing \ref
+  drawDecoration, which is called by the plottable's draw method. The base class \ref
+  QCPSelectionDecorator does not make use of this however. For example, \ref

+
+/*! \class QCPAbstractPlottable
+  \brief The abstract base class for all data representing objects in a plot.
+
+  It defines a very basic interface like name, pen, brush, visibility etc. Since this class is
+  abstract, it can't be instantiated. Use one of the subclasses or create a subclass yourself to
+  create new ways of displaying data (see "Creating own plottables" below). Plottables that display
+  one-dimensional data (i.e. data points have a single key dimension and one or multiple values at
+  each key) are based off of the template subclass \ref QCPAbstractPlottable1D, see details
+  there.
+  
+  All further specifics are in the subclasses, for example:
+  \li A normal graph with possibly a line and/or scatter points \ref QCPGraph
+  (typically created with \ref QCustomPlot::addGraph)
+  \li A parametric curve: \ref QCPCurve
+  \li A bar chart: \ref QCPBars
+  \li A statistical box plot: \ref QCPStatisticalBox
+  \li A color encoded two-dimensional map: \ref QCPColorMap
+  \li An OHLC/Candlestick chart: \ref QCPFinancial
+  
+  \section plottables-subclassing Creating own plottables
+  
+  Subclassing directly from QCPAbstractPlottable is only recommended if you wish to display
+  two-dimensional data like \ref QCPColorMap, i.e. two logical key dimensions and one (or more)
+  data dimensions. If you want to display data with only one logical key dimension, you should
+  rather derive from \ref QCPAbstractPlottable1D.
+  
+  If subclassing QCPAbstractPlottable directly, these are the pure virtual functions you must
+  implement:
+  \li \ref selectTest
+  \li \ref draw
+  \li \ref drawLegendIcon
+  \li \ref getKeyRange
+  \li \ref getValueRange
+  
+  See the documentation of those functions for what they need to do.
+  
+  For drawing your plot, you can use the \ref coordsToPixels functions to translate a point in plot
+  coordinates to pixel coordinates. This function is quite convenient, because it takes the
+  orientation of the key and value axes into account for you (x and y are swapped when the key axis
+  is vertical and the value axis horizontal). If you are worried about performance (i.e. you need
+  to translate many points in a loop like QCPGraph), you can directly use \ref
+  QCPAxis::coordToPixel. However, you must then take care about the orientation of the axis
+  yourself.
+  
+  Here are some important members you inherit from QCPAbstractPlottable:
+  <table>
+  <tr>
+    <td>QCustomPlot *\b mParentPlot</td>
+    <td>A pointer to the parent QCustomPlot instance. The parent plot is inferred from the axes that are passed in the constructor.</td>
+  </tr><tr>
+    <td>QString \b mName</td>
+    <td>The name of the plottable.</td>
+  </tr><tr>
+    <td>QPen \b mPen</td>
+    <td>The generic pen of the plottable. You should use this pen for the most prominent data representing lines in the plottable
+        (e.g QCPGraph uses this pen for its graph lines and scatters)</td>
+  </tr><tr>
+    <td>QBrush \b mBrush</td>
+    <td>The generic brush of the plottable. You should use this brush for the most prominent fillable structures in the plottable
+        (e.g. QCPGraph uses this brush to control filling under the graph)</td>
+  </tr><tr>
+    <td>QPointer<\ref QCPAxis> \b mKeyAxis, \b mValueAxis</td>
+    <td>The key and value axes this plottable is attached to. Call their QCPAxis::coordToPixel functions to translate coordinates
+        to pixels in either the key or value dimension. Make sure to check whether the pointer is null before using it. If one of
+        the axes is null, don't draw the plottable.</td>
+  </tr><tr>
+    <td>\ref QCPSelectionDecorator \b mSelectionDecorator</td>
+    <td>The currently set selection decorator which specifies how selected data of the plottable shall be drawn and decorated.
+        When drawing your data, you must consult this decorator for the appropriate pen/brush before drawing unselected/selected data segments.
+        Finally, you should call its \ref QCPSelectionDecorator::drawDecoration method at the end of your \ref draw implementation.</td>
+  </tr><tr>
+    <td>\ref QCP::SelectionType \b mSelectable</td>
+    <td>In which composition, if at all, this plottable's data may be selected. Enforcing this setting on the data selection is done
+        by QCPAbstractPlottable automatically.</td>
+  </tr><tr>
+    <td>\ref QCPDataSelection \b mSelection</td>
+    <td>Holds the current selection state of the plottable's data, i.e. the selected data ranges (\ref QCPDataRange).</td>

+/*! \class QCPItemAnchor
+  \brief An anchor of an item to which positions can be attached to.
+  
+  An item (QCPAbstractItem) may have one or more anchors. Unlike QCPItemPosition, an anchor doesn't
+  control anything on its item, but provides a way to tie other items via their positions to the
+  anchor.
+
+  For example, a QCPItemRect is defined by its positions \a topLeft and \a bottomRight.
+  Additionally it has various anchors like \a top, \a topRight or \a bottomLeft etc. So you can
+  attach the \a start (which is a QCPItemPosition) of a QCPItemLine to one of the anchors by
+  calling QCPItemPosition::setParentAnchor on \a start, passing the wanted anchor of the
+  QCPItemRect. This way the start of the line will now always follow the respective anchor location
+  on the rect item.
+  
+  Note that QCPItemPosition derives from QCPItemAnchor, so every position can also serve as an
+  anchor to other positions.
+  
+  To learn how to provide anchors in your own item subclasses, see the subclassing section of the
+  QCPAbstractItem documentation.

+/*! \class QCPItemPosition
+  \brief Manages the position of an item.
+  
+  Every item has at least one public QCPItemPosition member pointer which provides ways to position the
+  item on the QCustomPlot surface. Some items have multiple positions, for example QCPItemRect has two:
+  \a topLeft and \a bottomRight.
+
+  QCPItemPosition has a type (\ref PositionType) that can be set with \ref setType. This type
+  defines how coordinates passed to \ref setCoords are to be interpreted, e.g. as absolute pixel
+  coordinates, as plot coordinates of certain axes, etc. For more advanced plots it is also
+  possible to assign different types per X/Y coordinate of the position (see \ref setTypeX, \ref
+  setTypeY). This way an item could be positioned at a fixed pixel distance from the top in the Y
+  direction, while following a plot coordinate in the X direction.
+
+  A QCPItemPosition may have a parent QCPItemAnchor, see \ref setParentAnchor. This way you can tie
+  multiple items together. If the QCPItemPosition has a parent, its coordinates (\ref setCoords)
+  are considered to be absolute pixels in the reference frame of the parent anchor, where (0, 0)
+  means directly ontop of the parent anchor. For example, You could attach the \a start position of
+  a QCPItemLine to the \a bottom anchor of a QCPItemText to make the starting point of the line
+  always be centered under the text label, no matter where the text is moved to. For more advanced
+  plots, it is possible to assign different parent anchors per X/Y coordinate of the position, see
+  \ref setParentAnchorX, \ref setParentAnchorY. This way an item could follow another item in the X
+  direction but stay at a fixed position in the Y direction. Or even follow item A in X, and item B
+  in Y.
+
+  Note that every QCPItemPosition inherits from QCPItemAnchor and thus can itself be used as parent
+  anchor for other positions.
+
+  To set the apparent pixel position on the QCustomPlot surface directly, use \ref setPixelPosition. This
+  works no matter what type this QCPItemPosition is or what parent-child situation it is in, as \ref
+  setPixelPosition transforms the coordinates appropriately, to make the position appear at the specified
+  pixel values.

+/*! \class QCPAbstractItem
+  \brief The abstract base class for all items in a plot.
+  
+  In QCustomPlot, items are supplemental graphical elements that are neither plottables
+  (QCPAbstractPlottable) nor axes (QCPAxis). While plottables are always tied to two axes and thus
+  plot coordinates, items can also be placed in absolute coordinates independent of any axes. Each
+  specific item has at least one QCPItemPosition member which controls the positioning. Some items
+  are defined by more than one coordinate and thus have two or more QCPItemPosition members (For
+  example, QCPItemRect has \a topLeft and \a bottomRight).
+  
+  This abstract base class defines a very basic interface like visibility and clipping. Since this
+  class is abstract, it can't be instantiated. Use one of the subclasses or create a subclass
+  yourself to create new items.
+  
+  The built-in items are:
+  <table>
+  <tr><td>QCPItemLine</td><td>A line defined by a start and an end point. May have different ending styles on each side (e.g. arrows).</td></tr>
+  <tr><td>QCPItemStraightLine</td><td>A straight line defined by a start and a direction point. Unlike QCPItemLine, the straight line is infinitely long and has no endings.</td></tr>
+  <tr><td>QCPItemCurve</td><td>A curve defined by start, end and two intermediate control points. May have different ending styles on each side (e.g. arrows).</td></tr>
+  <tr><td>QCPItemRect</td><td>A rectangle</td></tr>
+  <tr><td>QCPItemEllipse</td><td>An ellipse</td></tr>
+  <tr><td>QCPItemPixmap</td><td>An arbitrary pixmap</td></tr>
+  <tr><td>QCPItemText</td><td>A text label</td></tr>
+  <tr><td>QCPItemBracket</td><td>A bracket which may be used to reference/highlight certain parts in the plot.</td></tr>
+  <tr><td>QCPItemTracer</td><td>An item that can be attached to a QCPGraph and sticks to its data points, given a key coordinate.</td></tr>
+  </table>
+  
+  \section items-clipping Clipping
+
+  Items are by default clipped to the main axis rect (they are only visible inside the axis rect).
+  To make an item visible outside that axis rect, disable clipping via \ref setClipToAxisRect
+  "setClipToAxisRect(false)".
+
+  On the other hand if you want the item to be clipped to a different axis rect, specify it via
+  \ref setClipAxisRect. This clipAxisRect property of an item is only used for clipping behaviour, and
+  in principle is independent of the coordinate axes the item might be tied to via its position
+  members (\ref QCPItemPosition::setAxes). However, it is common that the axis rect for clipping
+  also contains the axes used for the item positions.
+  
+  \section items-using Using items
+  
+  First you instantiate the item you want to use and add it to the plot:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-1
+  by default, the positions of the item are bound to the x- and y-Axis of the plot. So we can just
+  set the plot coordinates where the line should start/end:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-2
+  If we don't want the line to be positioned in plot coordinates but a different coordinate system,
+  e.g. absolute pixel positions on the QCustomPlot surface, we need to change the position type like this:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-3
+  Then we can set the coordinates, this time in pixels:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-4
+  and make the line visible on the entire QCustomPlot, by disabling clipping to the axis rect:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-5
+  
+  For more advanced plots, it is even possible to set different types and parent anchors per X/Y
+  coordinate of an item position, using for example \ref QCPItemPosition::setTypeX or \ref
+  QCPItemPosition::setParentAnchorX. For details, see the documentation of \ref QCPItemPosition.
+  
+  \section items-subclassing Creating own items
+  
+  To create an own item, you implement a subclass of QCPAbstractItem. These are the pure
+  virtual functions, you must implement:
+  \li \ref selectTest
+  \li \ref draw
+  
+  See the documentation of those functions for what they need to do.
+  
+  \subsection items-positioning Allowing the item to be positioned
+  
+  As mentioned, item positions are represented by QCPItemPosition members. Let's assume the new item shall
+  have only one point as its position (as opposed to two like a rect or multiple like a polygon). You then add
+  a public member of type QCPItemPosition like so:
+  
+  \code QCPItemPosition * const myPosition;\endcode
+  
+  the const makes sure the pointer itself can't be modified from the user of your new item (the QCPItemPosition
+  instance it points to, can be modified, of course).
+  The initialization of this pointer is made easy with the \ref createPosition function. Just assign
+  the return value of this function to each QCPItemPosition in the constructor of your item. \ref createPosition
+  takes a string which is the name of the position, typically this is identical to the variable name.
+  For example, the constructor of QCPItemExample could look like this:
+  
+  \code
+  QCPItemExample::QCPItemExample(QCustomPlot *parentPlot) :
+    QCPAbstractItem(parentPlot),
+    myPosition(createPosition("myPosition"))
+  {
+    // other constructor code
+  }
+  \endcode
+  
+  \subsection items-drawing The draw function
+  
+  To give your item a visual representation, reimplement the \ref draw function and use the passed
+  QCPPainter to draw the item. You can retrieve the item position in pixel coordinates from the
+  position member(s) via \ref QCPItemPosition::pixelPosition.
+
+  To optimize performance you should calculate a bounding rect first (don't forget to take the pen
+  width into account), check whether it intersects the \ref clipRect, and only draw the item at all
+  if this is the case.
+  
+  \subsection items-selection The selectTest function
+  
+  Your implementation of the \ref selectTest function may use the helpers \ref
+  QCPVector2D::distanceSquaredToLine and \ref rectDistance. With these, the implementation of the
+  selection test becomes significantly simpler for most items. See the documentation of \ref
+  selectTest for what the function parameters mean and what the function should return.
+  
+  \subsection anchors Providing anchors
+  
+  Providing anchors (QCPItemAnchor) starts off like adding a position. First you create a public
+  member, e.g.
+  
+  \code QCPItemAnchor * const bottom;\endcode
+
+  and create it in the constructor with the \ref createAnchor function, assigning it a name and an
+  anchor id (an integer enumerating all anchors on the item, you may create an own enum for this).
+  Since anchors can be placed anywhere, relative to the item's position(s), your item needs to
+  provide the position of every anchor with the reimplementation of the \ref anchorPixelPosition(int
+  anchorId) function.
+  
+  In essence the QCPItemAnchor is merely an intermediary that itself asks your item for the pixel
+  position when anything attached to the anchor needs to know the coordinates.

+  For details how to control which axes the user may drag/zoom and in what orientations, see \ref
+  QCPAxisRect::setRangeDrag, \ref QCPAxisRect::setRangeZoom, \ref QCPAxisRect::setRangeDragAxes,
+  \ref QCPAxisRect::setRangeZoomAxes.
+  
+  <b>Plottable data selection</b> is controlled by \ref QCP::iSelectPlottables. If \ref
+  QCP::iSelectPlottables is set, the user may select plottables (graphs, curves, bars,...) and
+  their data by clicking on them or in their vicinity (\ref setSelectionTolerance). Whether the
+  user can actually select a plottable and its data can further be restricted with the \ref
+  QCPAbstractPlottable::setSelectable method on the specific plottable. For details, see the
+  special page about the \ref dataselection "data selection mechanism". To retrieve a list of all
+  currently selected plottables, call \ref selectedPlottables. If you're only interested in
+  QCPGraphs, you may use the convenience function \ref selectedGraphs.
+  
+  <b>Item selection</b> is controlled by \ref QCP::iSelectItems. If \ref QCP::iSelectItems is set, the user
+  may select items (QCPItemLine, QCPItemText,...) by clicking on them or in their vicinity. To find
+  out whether a specific item is selected, call QCPAbstractItem::selected(). To retrieve a list of
+  all currently selected items, call \ref selectedItems.
+  
+  <b>Axis selection</b> is controlled with \ref QCP::iSelectAxes. If \ref QCP::iSelectAxes is set, the user
+  may select parts of the axes by clicking on them. What parts exactly (e.g. Axis base line, tick
+  labels, axis label) are selectable can be controlled via \ref QCPAxis::setSelectableParts for
+  each axis. To retrieve a list of all axes that currently contain selected parts, call \ref
+  selectedAxes. Which parts of an axis are selected, can be retrieved with QCPAxis::selectedParts().
+  
+  <b>Legend selection</b> is controlled with \ref QCP::iSelectLegend. If this is set, the user may
+  select the legend itself or individual items by clicking on them. What parts exactly are
+  selectable can be controlled via \ref QCPLegend::setSelectableParts. To find out whether the
+  legend or any of its child items are selected, check the value of QCPLegend::selectedParts. To
+  find out which child items are selected, call \ref QCPLegend::selectedItems.
+  
+  <b>All other selectable elements</b> The selection of all other selectable objects (e.g.
+  QCPTextElement, or your own layerable subclasses) is controlled with \ref QCP::iSelectOther. If set, the
+  user may select those objects by clicking on them. To find out which are currently selected, you
+  need to check their selected state explicitly.
+  
+  If the selection state has changed by user interaction, the \ref selectionChangedByUser signal is
+  emitted. Each selectable object additionally emits an individual selectionChanged signal whenever
+  their selection state has changed, i.e. not only by user interaction.
+  
+  To allow multiple objects to be selected by holding the selection modifier (\ref
+  setMultiSelectModifier), set the flag \ref QCP::iMultiSelect.
+  
+  \note In addition to the selection mechanism presented here, QCustomPlot always emits

+  \warning This is still an experimental feature and its performance depends on the system that it

+  might cause context conflicts on some systems.
+  
+  This method allows to enable OpenGL plot rendering, for increased plotting performance of
+  graphically demanding plots (thick lines, translucent fills, etc.).
+
+  If \a enabled is set to true, QCustomPlot will try to initialize OpenGL and, if successful,
+  continue plotting with hardware acceleration. The parameter \a multisampling controls how many
+  samples will be used per pixel, it essentially controls the antialiasing quality. If \a
+  multisampling is set too high for the current graphics hardware, the maximum allowed value will
+  be used.
+
+  You can test whether switching to OpenGL rendering was successful by checking whether the
+  according getter \a QCustomPlot::openGl() returns true. If the OpenGL initialization fails,
+  rendering continues with the regular software rasterizer, and an according qDebug output is
+  generated.
+
+  If switching to OpenGL was successful, this method disables label caching (\ref setPlottingHint
+  "setPlottingHint(QCP::phCacheLabels, false)") and turns on QCustomPlot's antialiasing override
+  for all elements (\ref setAntialiasedElements "setAntialiasedElements(QCP::aeAll)"), leading to a
+  higher quality output. The antialiasing override allows for pixel-grid aligned drawing in the
+  OpenGL paint device. As stated before, in OpenGL rendering the actual antialiasing of the plot is
+  controlled with \a multisampling. If \a enabled is set to false, the antialiasing/label caching
+  settings are restored to what they were before OpenGL was enabled, if they weren't altered in the
+  meantime.
+
+  \note OpenGL support is only enabled if QCustomPlot is compiled with the macro \c QCUSTOMPLOT_USE_OPENGL
+  defined. This define must be set before including the QCustomPlot header both during compilation
+  of the QCustomPlot library as well as when compiling your application. It is best to just include
+  the line <tt>DEFINES += QCUSTOMPLOT_USE_OPENGL</tt> in the respective qmake project files.
+  \note If you are using a Qt version before 5.0, you must also add the module "opengl" to your \c
+  QT variable in the qmake project files. For Qt versions 5.0 and higher, QCustomPlot switches to a
+  newer OpenGL interface which is already in the "gui" module.

+
+  Before the replot happens, the signal \ref beforeReplot is emitted. After the replot, \ref
+  afterReplot is emitted. It is safe to mutually connect the replot slot with any of those two

+  recursion.

+
+  If you use a high scaling factor, it is recommended to enable antialiasing for all elements by

+/*! \class QCPColorGradient
+  \brief Defines a color gradient for use with e.g. \ref QCPColorMap
+  
+  This class describes a color gradient which can be used to encode data with color. For example,
+  QCPColorMap and QCPColorScale have \ref QCPColorMap::setGradient "setGradient" methods which
+  take an instance of this class. Colors are set with \ref setColorStopAt(double position, const QColor &color)
+  with a \a position from 0 to 1. In between these defined color positions, the
+  color will be interpolated linearly either in RGB or HSV space, see \ref setColorInterpolation.
+
+  Alternatively, load one of the preset color gradients shown in the image below, with \ref
+  loadPreset, or by directly specifying the preset in the constructor.
+  
+  Apart from red, green and blue components, the gradient also interpolates the alpha values of the
+  configured color stops. This allows to display some portions of the data range as transparent in
+  the plot.
+  
+  \image html QCPColorGradient.png
+  
+  The \ref QCPColorGradient(GradientPreset preset) constructor allows directly converting a \ref
+  GradientPreset to a QCPColorGradient. This means that you can directly pass \ref GradientPreset
+  to all the \a setGradient methods, e.g.:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorgradient-setgradient
+  
+  The total number of levels used in the gradient can be set with \ref setLevelCount. Whether the
+  color gradient shall be applied periodically (wrapping around) to data values that lie outside
+  the data range specified on the plottable instance can be controlled with \ref setPeriodic.

+  By default, QCPAxisRect comes with four axes, at bottom, top, left and right. They can be
+  accessed via \ref axis by providing the respective axis type (\ref QCPAxis::AxisType) and index.
+  If you need all axes in the axis rect, use \ref axes. The top and right axes are set to be
+  invisible initially (QCPAxis::setVisible). To add more axes to a side, use \ref addAxis or \ref
+  addAxes. To remove an axis, use \ref removeAxis.
+  
+  The axis rect layerable itself only draws a background pixmap or color, if specified (\ref
+  setBackground). It is placed on the "background" layer initially (see \ref QCPLayer for an
+  explanation of the QCustomPlot layer system). The axes that are held by the axis rect can be
+  placed on other layers, independently of the axis rect.
+  
+  Every axis rect has a child layout of type \ref QCPLayoutInset. It is accessible via \ref
+  insetLayout and can be used to have other layout elements (or even other layouts with multiple
+  elements) hovering inside the axis rect.
+  
+  If an axis rect is clicked and dragged, it processes this by moving certain axis ranges. The
+  behaviour can be controlled with \ref setRangeDrag and \ref setRangeDragAxes. If the mouse wheel
+  is scrolled while the cursor is on the axis rect, certain axes are scaled. This is controllable
+  via \ref setRangeZoom, \ref setRangeZoomAxes and \ref setRangeZoomFactor. These interactions are
+  only enabled if \ref QCustomPlot::setInteractions contains \ref QCP::iRangeDrag and \ref
+  QCP::iRangeZoom.

+  wheel is turned rapidly, many steps may bunch up to one event, so the event->delta() may then be
+  multiples of 120. This is taken into account here, by calculating \a wheelSteps and using it as

+/*! \class QCPLegend
+  \brief Manages a legend inside a QCustomPlot.
+
+  A legend is a small box somewhere in the plot which lists plottables with their name and icon.
+
+  A legend is populated with legend items by calling \ref QCPAbstractPlottable::addToLegend on the
+  plottable, for which a legend item shall be created. In the case of the main legend (\ref
+  QCustomPlot::legend), simply adding plottables to the plot while \ref
+  QCustomPlot::setAutoAddPlottableToLegend is set to true (the default) creates corresponding
+  legend items. The legend item associated with a certain plottable can be removed with \ref
+  QCPAbstractPlottable::removeFromLegend. However, QCPLegend also offers an interface to add and
+  manipulate legend items directly: \ref item, \ref itemWithPlottable, \ref itemCount, \ref
+  addItem, \ref removeItem, etc.
+
+  Since \ref QCPLegend derives from \ref QCPLayoutGrid, it can be placed in any position a \ref
+  QCPLayoutElement may be positioned. The legend items are themselves \ref QCPLayoutElement
+  "QCPLayoutElements" which are placed in the grid layout of the legend. \ref QCPLegend only adds
+  an interface specialized for handling child elements of type \ref QCPAbstractLegendItem, as
+  mentioned above. In principle, any other layout elements may also be added to a legend via the
+  normal \ref QCPLayoutGrid interface. See the special page about \link thelayoutsystem The Layout
+  System\endlink for examples on how to add other elements to the legend and move it outside the axis
+  rect.
+
+  Use the methods \ref setFillOrder and \ref setWrap inherited from \ref QCPLayoutGrid to control
+  in which order (column first or row first) the legend is filled up when calling \ref addItem, and
+  at which column or row wrapping occurs.
+
+  By default, every QCustomPlot has one legend (\ref QCustomPlot::legend) which is placed in the
+  inset layout of the main axis rect (\ref QCPAxisRect::insetLayout). To move the legend to another
+  position inside the axis rect, use the methods of the \ref QCPLayoutInset. To move the legend
+  outside of the axis rect, place it anywhere else with the \ref QCPLayout/\ref QCPLayoutElement

+/*! \class QCPColorScale
+  \brief A color scale for use with color coding data such as QCPColorMap
+  
+  This layout element can be placed on the plot to correlate a color gradient with data values. It
+  is usually used in combination with one or multiple \ref QCPColorMap "QCPColorMaps".
+
+  \image html QCPColorScale.png
+  
+  The color scale can be either horizontal or vertical, as shown in the image above. The
+  orientation and the side where the numbers appear is controlled with \ref setType.
+  
+  Use \ref QCPColorMap::setColorScale to connect a color map with a color scale. Once they are
+  connected, they share their gradient, data range and data scale type (\ref setGradient, \ref
+  setDataRange, \ref setDataScaleType). Multiple color maps may be associated with a single color
+  scale, to make them all synchronize these properties.
+  
+  To have finer control over the number display and axis behaviour, you can directly access the
+  \ref axis. See the documentation of QCPAxis for details about configuring axes. For example, if
+  you want to change the number of automatically generated ticks, call
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorscale-tickcount
+  
+  Placing a color scale next to the main axis rect works like with any other layout element:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorscale-creation
+  In this case we have placed it to the right of the default axis rect, so it wasn't necessary to
+  call \ref setType, since \ref QCPAxis::atRight is already the default. The text next to the color
+  scale can be set with \ref setLabel.
+  
+  For optimum appearance (like in the image above), it may be desirable to line up the axis rect and
+  the borders of the color scale. Use a \ref QCPMarginGroup to achieve this:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorscale-margingroup
+  
+  Color scales are initialized with a non-zero minimum top and bottom margin (\ref
+  setMinimumMargins), because vertical color scales are most common and the minimum top/bottom
+  margin makes sure it keeps some distance to the top/bottom widget border. So if you change to a
+  horizontal color scale by setting \ref setType to \ref QCPAxis::atBottom or \ref QCPAxis::atTop, you
+  might want to also change the minimum margins accordingly, e.g. <tt>setMinimumMargins(QMargins(6, 0, 6, 0))</tt>.

+  \brief A plottable representing a graph in a plot.
+
+  \image html QCPGraph.png
+  
+  Usually you create new graphs by calling QCustomPlot::addGraph. The resulting instance can be
+  accessed via QCustomPlot::graph.
+
+  To plot data, assign it with the \ref setData or \ref addData functions. Alternatively, you can
+  also access and modify the data via the \ref data method, which returns a pointer to the internal
+  \ref QCPGraphDataContainer.
+  
+  Graphs are used to display single-valued data. Single-valued means that there should only be one
+  data point per unique key coordinate. In other words, the graph can't have \a loops. If you do
+  want to plot non-single-valued curves, rather use the QCPCurve plottable.
+  
+  Gaps in the graph line can be created by adding data points with NaN as value
+  (<tt>qQNaN()</tt> or <tt>std::numeric_limits<double>::quiet_NaN()</tt>) in between the two data points that shall be
+  separated.
+  
+  \section qcpgraph-appearance Changing the appearance
+  
+  The appearance of the graph is mainly determined by the line style, scatter style, brush and pen
+  of the graph (\ref setLineStyle, \ref setScatterStyle, \ref setBrush, \ref setPen).
+  
+  \subsection filling Filling under or between graphs
+  
+  QCPGraph knows two types of fills: Normal graph fills towards the zero-value-line parallel to
+  the key axis of the graph, and fills between two graphs, called channel fills. To enable a fill,
+  just set a brush with \ref setBrush which is neither Qt::NoBrush nor fully transparent.
+  
+  By default, a normal fill towards the zero-value-line will be drawn. To set up a channel fill
+  between this graph and another one, call \ref setChannelFillGraph with the other graph as
+  parameter.

+  
+  By default, adaptive sampling is enabled. Even if enabled, QCustomPlot decides whether adaptive

+  dramatically though. This allows QCustomPlot to display large amounts of data in realtime.
+  
+  \image html adaptive-sampling-scatter.png "A scatter plot of 100,000 points without and with adaptive sampling"

+  Care must be taken when using high-density scatter plots in combination with adaptive sampling.
+  The adaptive sampling algorithm treats scatter plots more carefully than line plots which still
+  gives a significant reduction of replot times, but not quite as much as for line plots. This is
+  because scatter plots inherently need more data points to be preserved in order to still resemble
+  the original, non-adaptive-sampling plot. As shown above, the results still aren't quite
+  identical, as banding occurs for the outer data points. This is in fact intentional, such that
+  the boundaries of the data cloud stay visible to the viewer. How strong the banding appears,
+  depends on the point density, i.e. the number of points in the plot.
+  
+  For some situations with scatter plots it might thus be desirable to manually turn adaptive
+  sampling off. For example, when saving the plot to disk. This can be achieved by setting \a
+  enabled to false before issuing a command like \ref QCustomPlot::savePng, and setting \a enabled

+  \brief A plottable representing a parametric curve in a plot.
+  
+  \image html QCPCurve.png
+  
+  Unlike QCPGraph, plottables of this type may have multiple points with the same key coordinate,
+  so their visual representation can have \a loops. This is realized by introducing a third
+  coordinate \a t, which defines the order of the points described by the other two coordinates \a
+  x and \a y.
+
+  To plot data, assign it with the \ref setData or \ref addData functions. Alternatively, you can
+  also access and modify the curve's data via the \ref data method, which returns a pointer to the
+  internal \ref QCPCurveDataContainer.
+  
+  Gaps in the curve can be created by adding data points with NaN as key and value
+  (<tt>qQNaN()</tt> or <tt>std::numeric_limits<double>::quiet_NaN()</tt>) in between the two data points that shall be
+  separated.
+  
+  \section qcpcurve-appearance Changing the appearance
+  
+  The appearance of the curve is determined by the pen and the brush (\ref setPen, \ref setBrush).
+  
+  \section qcpcurve-usage Usage
+  
+  Like all data representing objects in QCustomPlot, the QCPCurve is a plottable
+  (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
+  (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
+  
+  Usually, you first create an instance:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcurve-creation-1
+  which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot instance takes
+  ownership of the plottable, so do not delete it manually but use QCustomPlot::removePlottable() instead.
+  The newly created plottable can be modified, e.g.:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcurve-creation-2

+  printed to the debug output (qDebug), the construction is not aborted, though.

+  projecting them on the top and left borders of region 5 will create a segment that surely crosses
+  5, creating a visual artifact in the plot. This method prevents this by providing extra points at
+  the top left corner, making the optimized curve correctly pass from region 4 to 1 to 2 without
+  traversing 5.

+/*! \class QCPBarsGroup
+  \brief Groups multiple QCPBars together so they appear side by side
+  
+  \image html QCPBarsGroup.png
+  
+  When showing multiple QCPBars in one plot which have bars at identical keys, it may be desirable
+  to have them appearing next to each other at each key. This is what adding the respective QCPBars
+  plottables to a QCPBarsGroup achieves. (An alternative approach is to stack them on top of each
+  other, see \ref QCPBars::moveAbove.)
+  
+  \section qcpbarsgroup-usage Usage
+  
+  To add a QCPBars plottable to the group, create a new group and then add the respective bars
+  intances:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpbarsgroup-creation
+  Alternatively to appending to the group like shown above, you can also set the group on the
+  QCPBars plottable via \ref QCPBars::setBarsGroup.
+  
+  The spacing between the bars can be configured via \ref setSpacingType and \ref setSpacing. The
+  bars in this group appear in the plot in the order they were appended. To insert a bars plottable
+  at a certain index position, or to reposition a bars plottable which is already in the group, use
+  \ref insert.
+  
+  To remove specific bars from the group, use either \ref remove or call \ref
+  QCPBars::setBarsGroup "QCPBars::setBarsGroup(0)" on the respective bars plottable.
+  
+  To clear the entire group, call \ref clear, or simply delete the group.

+/*! \class QCPStatisticalBox
+  \brief A plottable representing a single statistical box in a plot.
+
+  \image html QCPStatisticalBox.png
+  
+  To plot data, assign it with the \ref setData or \ref addData functions. Alternatively, you can
+  also access and modify the data via the \ref data method, which returns a pointer to the internal
+  \ref QCPStatisticalBoxDataContainer.
+  
+  Additionally each data point can itself have a list of outliers, drawn as scatter points at the
+  key coordinate of the respective statistical box data point. They can either be set by using the
+  respective \ref addData(double,double,double,double,double,double,const QVector<double>&)
+  "addData" method or accessing the individual data points through \ref data, and setting the
+  <tt>QVector<double> outliers</tt> of the data points directly.
+  
+  \section qcpstatisticalbox-appearance Changing the appearance
+  
+  The appearance of each data point box, ranging from the lower to the upper quartile, is
+  controlled via \ref setPen and \ref setBrush. You may change the width of the boxes with \ref
+  setWidth in plot coordinates.
+
+  Each data point's visual representation also consists of two whiskers. Whiskers are the lines
+  which reach from the upper quartile to the maximum, and from the lower quartile to the minimum.
+  The appearance of the whiskers can be modified with: \ref setWhiskerPen, \ref setWhiskerBarPen,
+  \ref setWhiskerWidth. The whisker width is the width of the bar perpendicular to the whisker at
+  the top (for maximum) and bottom (for minimum). If the whisker pen is changed, make sure to set
+  the \c capStyle to \c Qt::FlatCap. Otherwise the backbone line might exceed the whisker bars by a
+  few pixels due to the pen cap being not perfectly flat.
+  
+  The median indicator line inside the box has its own pen, \ref setMedianPen.
+  
+  The outlier data points are drawn as normal scatter points. Their look can be controlled with
+  \ref setOutlierStyle
+  
+  \section qcpstatisticalbox-usage Usage
+  
+  Like all data representing objects in QCustomPlot, the QCPStatisticalBox is a plottable
+  (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
+  (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
+  
+  Usually, you first create an instance:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpstatisticalbox-creation-1
+  which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot instance takes
+  ownership of the plottable, so do not delete it manually but use QCustomPlot::removePlottable() instead.
+  The newly created plottable can be modified, e.g.:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpstatisticalbox-creation-2

+/*! \class QCPColorMapData
+  \brief Holds the two-dimensional data of a QCPColorMap plottable.
+  
+  This class is a data storage for \ref QCPColorMap. It holds a two-dimensional array, which \ref
+  QCPColorMap then displays as a 2D image in the plot, where the array values are represented by a
+  color, depending on the value.
+  
+  The size of the array can be controlled via \ref setSize (or \ref setKeySize, \ref setValueSize).
+  Which plot coordinates these cells correspond to can be configured with \ref setRange (or \ref
+  setKeyRange, \ref setValueRange).
+  
+  The data cells can be accessed in two ways: They can be directly addressed by an integer index
+  with \ref setCell. This is the fastest method. Alternatively, they can be addressed by their plot
+  coordinate with \ref setData. plot coordinate to cell index transformations and vice versa are
+  provided by the functions \ref coordToCell and \ref cellToCoord.
+  
+  A \ref QCPColorMapData also holds an on-demand two-dimensional array of alpha values which (if
+  allocated) has the same size as the data map. It can be accessed via \ref setAlpha, \ref
+  fillAlpha and \ref clearAlpha. The memory for the alpha map is only allocated if needed, i.e. on
+  the first call of \ref setAlpha. \ref clearAlpha restores full opacity and frees the alpha map.
+  
+  This class also buffers the minimum and maximum values that are in the data set, to provide
+  QCPColorMap::rescaleDataRange with the necessary information quickly. Setting a cell to a value
+  that is greater than the current maximum increases this maximum to the new value. However,
+  setting the cell that currently holds the maximum value to a smaller value doesn't decrease the
+  maximum again, because finding the true new maximum would require going through the entire data
+  array, which might be time consuming. The same holds for the data minimum. This functionality is
+  given by \ref recalculateDataBounds, such that you can decide when it is sensible to find the
+  true current minimum and maximum. The method QCPColorMap::rescaleDataRange offers a convenience
+  parameter \a recalculateDataBounds which may be set to true to automatically call \ref
+  recalculateDataBounds internally.

+/*! \class QCPColorMap
+  \brief A plottable representing a two-dimensional color map in a plot.
+
+  \image html QCPColorMap.png
+  
+  The data is stored in the class \ref QCPColorMapData, which can be accessed via the data()
+  method.
+  
+  A color map has three dimensions to represent a data point: The \a key dimension, the \a value
+  dimension and the \a data dimension. As with other plottables such as graphs, \a key and \a value
+  correspond to two orthogonal axes on the QCustomPlot surface that you specify in the QCPColorMap
+  constructor. The \a data dimension however is encoded as the color of the point at (\a key, \a
+  value).
+
+  Set the number of points (or \a cells) in the key/value dimension via \ref
+  QCPColorMapData::setSize. The plot coordinate range over which these points will be displayed is
+  specified via \ref QCPColorMapData::setRange. The first cell will be centered on the lower range
+  boundary and the last cell will be centered on the upper range boundary. The data can be set by
+  either accessing the cells directly with QCPColorMapData::setCell or by addressing the cells via
+  their plot coordinates with \ref QCPColorMapData::setData. If possible, you should prefer
+  setCell, since it doesn't need to do any coordinate transformation and thus performs a bit
+  better.
+  
+  The cell with index (0, 0) is at the bottom left, if the color map uses normal (i.e. not reversed)
+  key and value axes.
+  
+  To show the user which colors correspond to which \a data values, a \ref QCPColorScale is
+  typically placed to the right of the axis rect. See the documentation there for details on how to
+  add and use a color scale.
+  
+  \section qcpcolormap-appearance Changing the appearance
+  
+  The central part of the appearance is the color gradient, which can be specified via \ref
+  setGradient. See the documentation of \ref QCPColorGradient for details on configuring a color
+  gradient.
+  
+  The \a data range that is mapped to the colors of the gradient can be specified with \ref
+  setDataRange. To make the data range encompass the whole data set minimum to maximum, call \ref
+  rescaleDataRange.
+  
+  \section qcpcolormap-transparency Transparency
+  
+  Transparency in color maps can be achieved by two mechanisms. On one hand, you can specify alpha
+  values for color stops of the \ref QCPColorGradient, via the regular QColor interface. This will
+  cause the color map data which gets mapped to colors around those color stops to appear with the
+  accordingly interpolated transparency.
+  
+  On the other hand you can also directly apply an alpha value to each cell independent of its
+  data, by using the alpha map feature of \ref QCPColorMapData. The relevant methods are \ref
+  QCPColorMapData::setAlpha, QCPColorMapData::fillAlpha and \ref QCPColorMapData::clearAlpha().
+  
+  The two transparencies will be joined together in the plot and otherwise not interfere with each
+  other. They are mixed in a multiplicative matter, so an alpha of e.g. 50% (128/255) in both modes
+  simultaneously, will result in a total transparency of 25% (64/255).
+  
+  \section qcpcolormap-usage Usage
+  
+  Like all data representing objects in QCustomPlot, the QCPColorMap is a plottable
+  (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
+  (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
+  
+  Usually, you first create an instance:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolormap-creation-1
+  which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot instance takes
+  ownership of the plottable, so do not delete it manually but use QCustomPlot::removePlottable() instead.
+  The newly created plottable can be modified, e.g.:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolormap-creation-2
+  
+  \note The QCPColorMap always displays the data at equal key/value intervals, even if the key or
+  value axis is set to a logarithmic scaling. If you want to use QCPColorMap with logarithmic axes,
+  you shouldn't use the \ref QCPColorMapData::setData method as it uses a linear transformation to
+  determine the cell index. Rather directly access the cell index with \ref
+  QCPColorMapData::setCell.

+/*! \class QCPFinancial
+  \brief A plottable representing a financial stock chart
+
+  \image html QCPFinancial.png
+
+  This plottable represents time series data binned to certain intervals, mainly used for stock
+  charts. The two common representations OHLC (Open-High-Low-Close) bars and Candlesticks can be
+  set via \ref setChartStyle.
+
+  The data is passed via \ref setData as a set of open/high/low/close values at certain keys
+  (typically times). This means the data must be already binned appropriately. If data is only
+  available as a series of values (e.g. \a price against \a time), you can use the static
+  convenience function \ref timeSeriesToOhlc to generate binned OHLC-data which can then be passed
+  to \ref setData.
+
+  The width of the OHLC bars/candlesticks can be controlled with \ref setWidth and \ref
+  setWidthType. A typical choice is to set the width type to \ref wtPlotCoords (the default) and
+  the width to (or slightly less than) one time bin interval width.
+
+  \section qcpfinancial-appearance Changing the appearance
+
+  Charts can be either single- or two-colored (\ref setTwoColored). If set to be single-colored,
+  lines are drawn with the plottable's pen (\ref setPen) and fills with the brush (\ref setBrush).
+
+  If set to two-colored, positive changes of the value during an interval (\a close >= \a open) are
+  represented with a different pen and brush than negative changes (\a close < \a open). These can
+  be configured with \ref setPenPositive, \ref setPenNegative, \ref setBrushPositive, and \ref
+  setBrushNegative. In two-colored mode, the normal plottable pen/brush is ignored. Upon selection
+  however, the normal selected pen/brush (provided by the \ref selectionDecorator) is used,
+  irrespective of whether the chart is single- or two-colored.
+
+  \section qcpfinancial-usage Usage
+
+  Like all data representing objects in QCustomPlot, the QCPFinancial is a plottable
+  (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
+  (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
+
+  Usually, you first create an instance:
+
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpfinancial-creation-1
+  which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot
+  instance takes ownership of the plottable, so do not delete it manually but use
+  QCustomPlot::removePlottable() instead. The newly created plottable can be modified, e.g.:
+
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpfinancial-creation-2
+  Here we have used the static helper method \ref timeSeriesToOhlc, to turn a time-price data
+  series into a 24-hour binned open-high-low-close data series as QCPFinancial uses.

+  printed to the debug output (qDebug), the construction is not aborted, though.

+
+  \image html QCPErrorBars.png
+
+  The \ref QCPErrorBars plottable can be attached to other one-dimensional plottables (e.g. \ref
+  QCPGraph, \ref QCPCurve, \ref QCPBars, etc.) and equips them with error bars.
+
+  Use \ref setDataPlottable to define for which plottable the \ref QCPErrorBars shall display the
+  error bars. The orientation of the error bars can be controlled with \ref setErrorType.
+
+  By using \ref setData, you can supply the actual error data, either as symmetric error or
+  plus/minus asymmetric errors. \ref QCPErrorBars only stores the error data. The absolute
+  key/value position of each error bar will be adopted from the configured data plottable. The
+  error data of the \ref QCPErrorBars are associated one-to-one via their index to the data points
+  of the data plottable. You can directly access and manipulate the error bar data via \ref data.
+
+  Set either of the plus/minus errors to NaN (<tt>qQNaN()</tt> or
+  <tt>std::numeric_limits<double>::quiet_NaN()</tt>) to not show the respective error bar on the data point at
+  that index.
+
+  \section qcperrorbars-appearance Changing the appearance
+
+  The appearance of the error bars is defined by the pen (\ref setPen), and the width of the
+  whiskers (\ref setWhiskerWidth). Further, the error bar backbones may leave a gap around the data
+  point center to prevent that error bars are drawn too close to or even through scatter points.
+  This gap size can be controlled via \ref setSymbolGap.

+  \brief Item that sticks to QCPGraph data points
+
+  \image html QCPItemTracer.png "Tracer example. Blue dotted circles are anchors, solid blue discs are positions."
+
+  The tracer can be connected with a QCPGraph via \ref setGraph. Then it will automatically adopt
+  the coordinate axes of the graph and update its \a position to be on the graph's data. This means
+  the key stays controllable via \ref setGraphKey, but the value will follow the graph data. If a
+  QCPGraph is connected, note that setting the coordinates of the tracer item directly via \a
+  position will have no effect because they will be overriden in the next redraw (this is when the
+  coordinate update happens).
+  
+  If the specified key in \ref setGraphKey is outside the key bounds of the graph, the tracer will
+  stay at the corresponding end of the graph.
+  
+  With \ref setInterpolating you may specify whether the tracer may only stay exactly on data
+  points or whether it interpolates data points linearly, if given a key that lies between two data
+  points of the graph.
+  
+  The tracer has different visual styles, see \ref setStyle. It is also possible to make the tracer
+  have no own visual appearance (set the style to \ref tsNone), and just connect other item
+  positions to the tracer \a position (used as an anchor) via \ref
+  QCPItemPosition::setParentAnchor.
+  
+  \note The tracer position is only automatically updated upon redraws. So when the data of the
+  graph changes and immediately afterwards (without a redraw) the position coordinates of the
+  tracer are retrieved, they will not reflect the updated data of the graph. In this case \ref
+  updatePosition must be called manually, prior to reading the tracer coordinates.

+/*! \class QCPDataContainer
+  \brief The generic data container for one-dimensional plottables
+
+  This class template provides a fast container for data storage of one-dimensional data. The data
+  type is specified as template parameter (called \a DataType in the following) and must provide
+  some methods as described in the \ref qcpdatacontainer-datatype "next section".
+
+  The data is stored in a sorted fashion, which allows very quick lookups by the sorted key as well
+  as retrieval of ranges (see \ref findBegin, \ref findEnd, \ref keyRange) using binary search. The
+  container uses a preallocation and a postallocation scheme, such that appending and prepending
+  data (with respect to the sort key) is very fast and minimizes reallocations. If data is added
+  which needs to be inserted between existing keys, the merge usually can be done quickly too,
+  using the fact that existing data is always sorted. The user can further improve performance by
+  specifying that added data is already itself sorted by key, if he can guarantee that this is the
+  case (see for example \ref add(const QVector<DataType> &data, bool alreadySorted)).
+
+  The data can be accessed with the provided const iterators (\ref constBegin, \ref constEnd). If
+  it is necessary to alter existing data in-place, the non-const iterators can be used (\ref begin,
+  \ref end). Changing data members that are not the sort key (for most data types called \a key) is
+  safe from the container's perspective.
+
+  Great care must be taken however if the sort key is modified through the non-const iterators. For
+  performance reasons, the iterators don't automatically cause a re-sorting upon their
+  manipulation. It is thus the responsibility of the user to leave the container in a sorted state
+  when finished with the data manipulation, before calling any other methods on the container. A
+  complete re-sort (e.g. after finishing all sort key manipulation) can be done by calling \ref
+  sort. Failing to do so can not be detected by the container efficiently and will cause both
+  rendering artifacts and potential data loss.
+
+  Implementing one-dimensional plottables that make use of a \ref QCPDataContainer<T> is usually
+  done by subclassing from \ref QCPAbstractPlottable1D "QCPAbstractPlottable1D<T>", which
+  introduces an according \a mDataContainer member and some convenience methods.
+
+  \section qcpdatacontainer-datatype Requirements for the DataType template parameter
+
+  The template parameter <tt>DataType</tt> is the type of the stored data points. It must be
+  trivially copyable and have the following public methods, preferably inline:
+
+  \li <tt>double sortKey() const</tt>\n Returns the member variable of this data point that is the
+  sort key, defining the ordering in the container. Often this variable is simply called \a key.
+
+  \li <tt>static DataType fromSortKey(double sortKey)</tt>\n Returns a new instance of the data
+  type initialized with its sort key set to \a sortKey.
+
+  \li <tt>static bool sortKeyIsMainKey()</tt>\n Returns true if the sort key is equal to the main
+  key (see method \c mainKey below). For most plottables this is the case. It is not the case for
+  example for \ref QCPCurve, which uses \a t as sort key and \a key as main key. This is the reason
+  why QCPCurve unlike QCPGraph can display parametric curves with loops.
+
+  \li <tt>double mainKey() const</tt>\n Returns the variable of this data point considered the main
+  key. This is commonly the variable that is used as the coordinate of this data point on the key
+  axis of the plottable. This method is used for example when determining the automatic axis
+  rescaling of key axes (\ref QCPAxis::rescale).
+
+  \li <tt>double mainValue() const</tt>\n Returns the variable of this data point considered the
+  main value. This is commonly the variable that is used as the coordinate of this data point on
+  the value axis of the plottable.
+
+  \li <tt>QCPRange valueRange() const</tt>\n Returns the range this data point spans in the value
+  axis coordinate. If the data is single-valued (e.g. QCPGraphData), this is simply a range with
+  both lower and upper set to the main data point value. However if the data points can represent
+  multiple values at once (e.g QCPFinancialData with its \a high, \a low, \a open and \a close
+  values at each \a key) this method should return the range those values span. This method is used
+  for example when determining the automatic axis rescaling of value axes (\ref
+  QCPAxis::rescale).

+/*! \class QCPPlottableInterface1D
+  \brief Defines an abstract interface for one-dimensional plottables
+
+  This class contains only pure virtual methods which define a common interface to the data
+  of one-dimensional plottables.
+
+  For example, it is implemented by the template class \ref QCPAbstractPlottable1D (the preferred
+  base class for one-dimensional plottables). So if you use that template class as base class of
+  your one-dimensional plottable, you won't have to care about implementing the 1d interface
+  yourself.
+
+  If your plottable doesn't derive from \ref QCPAbstractPlottable1D but still wants to provide a 1d
+  interface (e.g. like \ref QCPErrorBars does), you should inherit from both \ref
+  QCPAbstractPlottable and \ref QCPPlottableInterface1D and accordingly reimplement the pure
+  virtual methods of the 1d interface, matching your data container. Also, reimplement \ref
+  QCPAbstractPlottable::interface1D to return the \c this pointer.
+
+  If you have a \ref QCPAbstractPlottable pointer, you can check whether it implements this
+  interface by calling \ref QCPAbstractPlottable::interface1D and testing it for a non-zero return
+  value. If it indeed implements this interface, you may use it to access the plottable's data
+  without needing to know the exact type of the plottable or its data point type.

+/*! \class QCPAbstractPlottable1D
+  \brief A template base class for plottables with one-dimensional data
+
+  This template class derives from \ref QCPAbstractPlottable and from the abstract interface \ref
+  QCPPlottableInterface1D. It serves as a base class for all one-dimensional data (i.e. data with
+  one key dimension), such as \ref QCPGraph and QCPCurve.
+
+  The template parameter \a DataType is the type of the data points of this plottable (e.g. \ref
+  QCPGraphData or \ref QCPCurveData). The main purpose of this base class is to provide the member
+  \a mDataContainer (a shared pointer to a \ref QCPDataContainer "QCPDataContainer<DataType>") and
+  implement the according virtual methods of the \ref QCPPlottableInterface1D, such that most
+  subclassed plottables don't need to worry about this anymore.
+
+  Further, it provides a convenience method for retrieving selected/unselected data segments via
+  \ref getDataSegments. This is useful when subclasses implement their \ref draw method and need to
+  draw selected segments with a different pen/brush than unselected segments (also see \ref
+  QCPSelectionDecorator).
+
+  This class implements basic functionality of \ref QCPAbstractPlottable::selectTest and \ref
+  QCPPlottableInterface1D::selectTestRect, assuming point-like data points, based on the 1D data
+  interface. In spite of that, most plottable subclasses will want to reimplement those methods
+  again, to provide a more accurate hit test based on their specific data visualization geometry.

-  \brief The abstract base class for paint buffers, which define the rendering backend
-
-  This abstract base class defines the basic interface that a paint buffer needs to provide in
-  order to be usable by QCustomPlot.
-
-  A paint buffer manages both a surface to draw onto, and the matching paint device. The size of
-  the surface can be changed via \ref setSize. External classes (\ref QCustomPlot and \ref
-  QCPLayer) request a painter via \ref startPainting and then perform the draw calls. Once the
-  painting is complete, \ref donePainting is called, so the paint buffer implementation can do
-  clean up if necessary. Before rendering a frame, each paint buffer is usually filled with a color
-  using \ref clear (usually the color is \c Qt::transparent), to remove the contents of the
-  previous frame.
-
-  The simplest paint buffer implementation is \ref QCPPaintBufferPixmap which allows regular
-  software rendering via the raster engine. Hardware accelerated rendering via pixel buffers and
-  frame buffer objects is provided by \ref QCPPaintBufferGlPbuffer and \ref QCPPaintBufferGlFbo.
-  They are used automatically if \ref QCustomPlot::setOpenGl is enabled.

-/*! \class QCPLayer
-  \brief A layer that may contain objects, to control the rendering order
-
-  The Layering system of QCustomPlot is the mechanism to control the rendering order of the
-  elements inside the plot.
-
-  It is based on the two classes QCPLayer and QCPLayerable. QCustomPlot holds an ordered list of
-  one or more instances of QCPLayer (see QCustomPlot::addLayer, QCustomPlot::layer,
-  QCustomPlot::moveLayer, etc.). When replotting, QCustomPlot goes through the list of layers
-  bottom to top and successively draws the layerables of the layers into the paint buffer(s).
-
-  A QCPLayer contains an ordered list of QCPLayerable instances. QCPLayerable is an abstract base
-  class from which almost all visible objects derive, like axes, grids, graphs, items, etc.
-
-  \section qcplayer-defaultlayers Default layers
-
-  Initially, QCustomPlot has six layers: "background", "grid", "main", "axes", "legend" and
-  "overlay" (in that order). On top is the "overlay" layer, which only contains the QCustomPlot's
-  selection rect (\ref QCustomPlot::selectionRect). The next two layers "axes" and "legend" contain
-  the default axes and legend, so they will be drawn above plottables. In the middle, there is the
-  "main" layer. It is initially empty and set as the current layer (see
-  QCustomPlot::setCurrentLayer). This means, all new plottables, items etc. are created on this
-  layer by default. Then comes the "grid" layer which contains the QCPGrid instances (which belong
-  tightly to QCPAxis, see \ref QCPAxis::grid). The Axis rect background shall be drawn behind
-  everything else, thus the default QCPAxisRect instance is placed on the "background" layer. Of
-  course, the layer affiliation of the individual objects can be changed as required (\ref
-  QCPLayerable::setLayer).
-
-  \section qcplayer-ordering Controlling the rendering order via layers
-
-  Controlling the ordering of layerables in the plot is easy: Create a new layer in the position
-  you want the layerable to be in, e.g. above "main", with \ref QCustomPlot::addLayer. Then set the
-  current layer with \ref QCustomPlot::setCurrentLayer to that new layer and finally create the
-  objects normally. They will be placed on the new layer automatically, due to the current layer
-  setting. Alternatively you could have also ignored the current layer setting and just moved the
-  objects with \ref QCPLayerable::setLayer to the desired layer after creating them.
-
-  It is also possible to move whole layers. For example, If you want the grid to be shown in front
-  of all plottables/items on the "main" layer, just move it above "main" with
-  QCustomPlot::moveLayer.
-
-  The rendering order within one layer is simply by order of creation or insertion. The item
-  created last (or added last to the layer), is drawn on top of all other objects on that layer.
-
-  When a layer is deleted, the objects on it are not deleted with it, but fall on the layer below
-  the deleted layer, see QCustomPlot::removeLayer.
-
-  \section qcplayer-buffering Replotting only a specific layer
-
-  If the layer mode (\ref setMode) is set to \ref lmBuffered, you can replot only this specific
-  layer by calling \ref replot. In certain situations this can provide better replot performance,
-  compared with a full replot of all layers. Upon creation of a new layer, the layer mode is
-  initialized to \ref lmLogical. The only layer that is set to \ref lmBuffered in a new \ref
-  QCustomPlot instance is the "overlay" layer, containing the selection rect.

-  
-  This function applies the default antialiasing setting to the specified \a painter, using the
-  function \ref applyAntialiasingHint. It is the antialiasing state the painter is put in, when
-  \ref draw is called on the layerable. If the layerable has multiple entities whose antialiasing
-  setting may be specified individually, this function should set the antialiasing state of the
-  most prominent entity. In this case however, the \ref draw function usually calls the specialized
-  versions of this function before drawing each entity, effectively overriding the setting of the
-  default antialiasing hint.
-  
-  <b>First example:</b> QCPGraph has multiple entities that have an antialiasing setting: The graph
-  line, fills and scatters. Those can be configured via QCPGraph::setAntialiased,
-  QCPGraph::setAntialiasedFill and QCPGraph::setAntialiasedScatters. Consequently, there isn't only
-  the QCPGraph::applyDefaultAntialiasingHint function (which corresponds to the graph line's
-  antialiasing), but specialized ones like QCPGraph::applyFillAntialiasingHint and
-  QCPGraph::applyScattersAntialiasingHint. So before drawing one of those entities, QCPGraph::draw
-  calls the respective specialized applyAntialiasingHint function.
-  
-  <b>Second example:</b> QCPItemLine consists only of a line so there is only one antialiasing
-  setting which can be controlled with QCPItemLine::setAntialiased. (This function is inherited by
-  all layerables. The specialized functions, as seen on QCPGraph, must be added explicitly to the
-  respective layerable subclass.) Consequently it only has the normal
-  QCPItemLine::applyDefaultAntialiasingHint. The \ref QCPItemLine::draw function doesn't need to
-  care about setting any antialiasing states, because the default antialiasing hint is already set
-  on the painter when the \ref draw function is called, and that's the state it wants to draw the

-  This function is used to decide whether a click hits a layerable object or not.
-
-  \a pos is a point in pixel coordinates on the QCustomPlot surface. This function returns the
-  shortest pixel distance of this point to the object. If the object is either invisible or the
-  distance couldn't be determined, -1.0 is returned. Further, if \a onlySelectable is true and the
-  object is not selectable, -1.0 is returned, too.
-
-  If the object is represented not by single lines but by an area like a \ref QCPItemText or the
-  bars of a \ref QCPBars plottable, a click inside the area should also be considered a hit. In
-  these cases this function thus returns a constant value greater zero but still below the parent
-  plot's selection tolerance. (typically the selectionTolerance multiplied by 0.99).
-  
-  Providing a constant value for area objects allows selecting line objects even when they are
-  obscured by such area objects, by clicking close to the lines (i.e. closer than
-  0.99*selectionTolerance).
-  
-  The actual setting of the selection state is not done by this function. This is handled by the
-  parent QCustomPlot when the mouseReleaseEvent occurs, and the finally selected object is notified
-  via the \ref selectEvent/\ref deselectEvent methods.
-  
-  \a details is an optional output parameter. Every layerable subclass may place any information
-  in \a details. This information will be passed to \ref selectEvent when the parent QCustomPlot
-  decides on the basis of this selectTest call, that the object was successfully selected. The
-  subsequent call to \ref selectEvent will carry the \a details. This is useful for multi-part
-  objects (like QCPAxis). This way, a possibly complex calculation to decide which part was clicked
-  is only done once in \ref selectTest. The result (i.e. the actually clicked part) can then be
-  placed in \a details. So in the subsequent \ref selectEvent, the decision which part was
-  selected doesn't have to be done a second time for a single selection operation.

-/*! \class QCPDataRange
-  \brief Describes a data range given by begin and end index
-  
-  QCPDataRange holds two integers describing the begin (\ref setBegin) and end (\ref setEnd) index
-  of a contiguous set of data points. The end index points to the data point above the last data point that's part of
-  the data range, similarly to the nomenclature used in standard iterators.
-  
-  Data Ranges are not bound to a certain plottable, thus they can be freely exchanged, created and
-  modified. If a non-contiguous data set shall be described, the class \ref QCPDataSelection is
-  used, which holds and manages multiple instances of \ref QCPDataRange. In most situations, \ref
-  QCPDataSelection is thus used.
-  
-  Both \ref QCPDataRange and \ref QCPDataSelection offer convenience methods to work with them,
-  e.g. \ref bounded, \ref expanded, \ref intersects, \ref intersection, \ref adjusted, \ref
-  contains. Further, addition and subtraction operators (defined in \ref QCPDataSelection) can be
-  used to join/subtract data ranges and data selections (or mixtures), to retrieve a corresponding
-  \ref QCPDataSelection.
-  
-  %QCustomPlot's \ref dataselection "data selection mechanism" is based on \ref QCPDataSelection and
-  QCPDataRange.
-  
-  \note Do not confuse \ref QCPDataRange with \ref QCPRange. A \ref QCPRange describes an interval
-  in floating point plot coordinates, e.g. the current axis range.

-/*! \class QCPDataSelection
-  \brief Describes a data set by holding multiple QCPDataRange instances
-  
-  QCPDataSelection manages multiple instances of QCPDataRange in order to represent any (possibly
-  disjoint) set of data selection.
-  
-  The data selection can be modified with addition and subtraction operators which take
-  QCPDataSelection and QCPDataRange instances, as well as methods such as \ref addDataRange and
-  \ref clear. Read access is provided by \ref dataRange, \ref dataRanges, \ref dataRangeCount, etc.
-  
-  The method \ref simplify is used to join directly adjacent or even overlapping QCPDataRange
-  instances. QCPDataSelection automatically simplifies when using the addition/subtraction
-  operators. The only case when \ref simplify is left to the user, is when calling \ref
-  addDataRange, with the parameter \a simplify explicitly set to false. This is useful if many data
-  ranges will be added to the selection successively and the overhead for simplifying after each
-  iteration shall be avoided. In this case, you should make sure to call \ref simplify after
-  completing the operation.
-  
-  Use \ref enforceType to bring the data selection into a state complying with the constraints for
-  selections defined in \ref QCP::SelectionType.
-

-  \brief Provides rect/rubber-band data selection and range zoom interaction
-  
-  QCPSelectionRect is used by QCustomPlot when the \ref QCustomPlot::setSelectionRectMode is not
-  \ref QCP::srmNone. When the user drags the mouse across the plot, the current selection rect
-  instance (\ref QCustomPlot::setSelectionRect) is forwarded these events and makes sure an

-  emits the corresponding signals \ref started, \ref changed, \ref canceled, and \ref accepted.
-  
-  The QCustomPlot instance connects own slots to the current selection rect instance, in order to
-  react to an accepted selection rect interaction accordingly.
-  
-  \ref isActive can be used to check whether the selection rect is currently active. An ongoing
-  selection interaction can be cancelled programmatically via calling \ref cancel at any time.
-  
-  The appearance of the selection rect can be controlled via \ref setPen and \ref setBrush.
-
-  If you wish to provide custom behaviour, e.g. a different visual representation of the selection

-/*! \class QCPMarginGroup
-  \brief A margin group allows synchronization of margin sides if working with multiple layout elements.
-  
-  QCPMarginGroup allows you to tie a margin side of two or more layout elements together, such that
-  they will all have the same size, based on the largest required margin in the group.
-  
-  \n
-  \image html QCPMarginGroup.png "Demonstration of QCPMarginGroup"
-  \n
-  
-  In certain situations it is desirable that margins at specific sides are synchronized across
-  layout elements. For example, if one QCPAxisRect is below another one in a grid layout, it will
-  provide a cleaner look to the user if the left and right margins of the two axis rects are of the
-  same size. The left axis of the top axis rect will then be at the same horizontal position as the
-  left axis of the lower axis rect, making them appear aligned. The same applies for the right
-  axes. This is what QCPMarginGroup makes possible.
-  
-  To add/remove a specific side of a layout element to/from a margin group, use the \ref
-  QCPLayoutElement::setMarginGroup method. To completely break apart the margin group, either call
-  \ref clear, or just delete the margin group.
-  
-  \section QCPMarginGroup-example Example
-  
-  First create a margin group:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpmargingroup-creation-1
-  Then set this group on the layout element sides:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpmargingroup-creation-2
-  Here, we've used the first two axis rects of the plot and synchronized their left margins with
-  each other and their right margins with each other.

-/*! \class QCPLayoutElement
-  \brief The abstract base class for all objects that form \ref thelayoutsystem "the layout system".
-  
-  This is an abstract base class. As such, it can't be instantiated directly, rather use one of its subclasses.
-  
-  A Layout element is a rectangular object which can be placed in layouts. It has an outer rect
-  (QCPLayoutElement::outerRect) and an inner rect (\ref QCPLayoutElement::rect). The difference
-  between outer and inner rect is called its margin. The margin can either be set to automatic or
-  manual (\ref setAutoMargins) on a per-side basis. If a side is set to manual, that margin can be
-  set explicitly with \ref setMargins and will stay fixed at that value. If it's set to automatic,
-  the layout element subclass will control the value itself (via \ref calculateAutoMargin).
-  
-  Layout elements can be placed in layouts (base class QCPLayout) like QCPLayoutGrid. The top level
-  layout is reachable via \ref QCustomPlot::plotLayout, and is a \ref QCPLayoutGrid. Since \ref
-  QCPLayout itself derives from \ref QCPLayoutElement, layouts can be nested.
-  
-  Thus in QCustomPlot one can divide layout elements into two categories: The ones that are
-  invisible by themselves, because they don't draw anything. Their only purpose is to manage the
-  position and size of other layout elements. This category of layout elements usually use
-  QCPLayout as base class. Then there is the category of layout elements which actually draw
-  something. For example, QCPAxisRect, QCPLegend and QCPTextElement are of this category. This does
-  not necessarily mean that the latter category can't have child layout elements. QCPLegend for
-  instance, actually derives from QCPLayoutGrid and the individual legend items are child layout
-  elements in the grid layout.

-/*! \class QCPLayout
-  \brief The abstract base class for layouts
-  
-  This is an abstract base class for layout elements whose main purpose is to define the position
-  and size of other child layout elements. In most cases, layouts don't draw anything themselves
-  (but there are exceptions to this, e.g. QCPLegend).
-  
-  QCPLayout derives from QCPLayoutElement, and thus can itself be nested in other layouts.
-  
-  QCPLayout introduces a common interface for accessing and manipulating the child elements. Those
-  functions are most notably \ref elementCount, \ref elementAt, \ref takeAt, \ref take, \ref
-  simplify, \ref removeAt, \ref remove and \ref clear. Individual subclasses may add more functions
-  to this interface which are more specialized to the form of the layout. For example, \ref
-  QCPLayoutGrid adds functions that take row and column indices to access cells of the layout grid
-  more conveniently.
-  
-  Since this is an abstract base class, you can't instantiate it directly. Rather use one of its
-  subclasses like QCPLayoutGrid or QCPLayoutInset.
-  
-  For a general introduction to the layout system, see the dedicated documentation page \ref
-  thelayoutsystem "The Layout System".

-/*! \class QCPLayoutGrid
-  \brief A layout that arranges child elements in a grid
-
-  Elements are laid out in a grid with configurable stretch factors (\ref setColumnStretchFactor,
-  \ref setRowStretchFactor) and spacing (\ref setColumnSpacing, \ref setRowSpacing).
-
-  Elements can be added to cells via \ref addElement. The grid is expanded if the specified row or
-  column doesn't exist yet. Whether a cell contains a valid layout element can be checked with \ref
-  hasElement, that element can be retrieved with \ref element. If rows and columns that only have
-  empty cells shall be removed, call \ref simplify. Removal of elements is either done by just
-  adding the element to a different layout or by using the QCPLayout interface \ref take or \ref
-  remove.
-
-  If you use \ref addElement(QCPLayoutElement*) without explicit parameters for \a row and \a
-  column, the grid layout will choose the position according to the current \ref setFillOrder and
-  the wrapping (\ref setWrap).
-
-  Row and column insertion can be performed with \ref insertRow and \ref insertColumn.

-  
-  \image html QCPLineEnding.png "The various ending styles currently supported"
-  
-  For every ending a line-like item has, an instance of this class exists. For example, QCPItemLine
-  has two endings which can be set with QCPItemLine::setHead and QCPItemLine::setTail.
- 
-  The styles themselves are defined via the enum QCPLineEnding::EndingStyle. Most decorations can
-  be modified regarding width and length, see \ref setWidth and \ref setLength. The direction of
-  the ending decoration (e.g. direction an arrow is pointing) is controlled by the line-like item.
-  For example, when both endings of a QCPItemLine are set to be arrows, they will point to opposite
-  directions, e.g. "outward". This can be changed by \ref setInverted, which would make the
-  respective arrow point inward.
-  
-  Note that due to the overloaded QCPLineEnding constructor, you may directly specify a
-  QCPLineEnding::EndingStyle where actually a QCPLineEnding is expected, e.g.

-/*! \class QCPAxisTicker
-  \brief The base class tick generator used by QCPAxis to create tick positions and tick labels
-  
-  Each QCPAxis has an internal QCPAxisTicker (or a subclass) in order to generate tick positions
-  and tick labels for the current axis range. The ticker of an axis can be set via \ref
-  QCPAxis::setTicker. Since that method takes a <tt>QSharedPointer<QCPAxisTicker></tt>, multiple
-  axes can share the same ticker instance.
-  
-  This base class generates normal tick coordinates and numeric labels for linear axes. It picks a
-  reasonable tick step (the separation between ticks) which results in readable tick labels. The
-  number of ticks that should be approximately generated can be set via \ref setTickCount.
-  Depending on the current tick step strategy (\ref setTickStepStrategy), the algorithm either
-  sacrifices readability to better match the specified tick count (\ref
-  QCPAxisTicker::tssMeetTickCount) or relaxes the tick count in favor of better tick steps (\ref
-  QCPAxisTicker::tssReadability), which is the default.
-  
-  The following more specialized axis ticker subclasses are available, see details in the
-  respective class documentation:

-  \section axisticker-subclassing Creating own axis tickers
-  
-  Creating own axis tickers can be achieved very easily by sublassing QCPAxisTicker and
-  reimplementing some or all of the available virtual methods.
-
-  In the simplest case you might wish to just generate different tick steps than the other tickers,
-  so you only reimplement the method \ref getTickStep. If you additionally want control over the
-  string that will be shown as tick label, reimplement \ref getTickLabel.
-  
-  If you wish to have complete control, you can generate the tick vectors and tick label vectors
-  yourself by reimplementing \ref createTickVector and \ref createLabelVector. The default
-  implementations use the previously mentioned virtual methods \ref getTickStep and \ref
-  getTickLabel, but your reimplementations don't necessarily need to do so. For example in the case
-  of unequal tick steps, the method \ref getTickStep loses its usefulness and can be ignored.
-  
-  The sub tick count between major ticks can be controlled with \ref getSubTickCount. Full sub tick
-  placement control is obtained by reimplementing \ref createSubTickVector.
-  
-  See the documentation of all these virtual methods in QCPAxisTicker for detailed information
-  about the parameters and expected return values.

-/*! \class QCPAxisTickerDateTime
-  \brief Specialized axis ticker for calendar dates and times as axis ticks
-  
-  \image html axisticker-datetime.png
-  
-  This QCPAxisTicker subclass generates ticks that correspond to real calendar dates and times. The
-  plot axis coordinate is interpreted as Unix Time, so seconds since Epoch (January 1, 1970, 00:00
-  UTC). This is also used for example by QDateTime in the <tt>toTime_t()/setTime_t()</tt> methods
-  with a precision of one second. Since Qt 4.7, millisecond accuracy can be obtained from QDateTime
-  by using <tt>QDateTime::fromMSecsSinceEpoch()/1000.0</tt>. The static methods \ref dateTimeToKey
-  and \ref keyToDateTime conveniently perform this conversion achieving a precision of one
-  millisecond on all Qt versions.
-  
-  The format of the date/time display in the tick labels is controlled with \ref setDateTimeFormat.
-  If a different time spec (time zone) shall be used, see \ref setDateTimeSpec.
-  
-  This ticker produces unequal tick spacing in order to provide intuitive date and time-of-day
-  ticks. For example, if the axis range spans a few years such that there is one tick per year,
-  ticks will be positioned on 1. January of every year. This is intuitive but, due to leap years,
-  will result in slightly unequal tick intervals (visually unnoticeable). The same can be seen in
-  the image above: even though the number of days varies month by month, this ticker generates
-  ticks on the same day of each month.
-  
-  If you would like to change the date/time that is used as a (mathematical) starting date for the
-  ticks, use the \ref setTickOrigin(const QDateTime &origin) method overload, which takes a
-  QDateTime. If you pass 15. July, 9:45 to this method, the yearly ticks will end up on 15. July at
-  9:45 of every year.
-  
-  The ticker can be created and assigned to an axis like this:
-  \snippet documentation/doc-image-generator/mainwindow.cpp axistickerdatetime-creation
-  
-  \note If you rather wish to display relative times in terms of days, hours, minutes, seconds and
-  milliseconds, and are not interested in the intricacies of real calendar dates with months and
-  (leap) years, have a look at QCPAxisTickerTime instead.

-  \brief Specialized axis ticker for time spans in units of milliseconds to days
-  
-  \image html axisticker-time.png
-  
-  This QCPAxisTicker subclass generates ticks that corresponds to time intervals.
-  
-  The format of the time display in the tick labels is controlled with \ref setTimeFormat and \ref
-  setFieldWidth. The time coordinate is in the unit of seconds with respect to the time coordinate
-  zero. Unlike with QCPAxisTickerDateTime, the ticks don't correspond to a specific calendar date
-  and time.
-  
-  The time can be displayed in milliseconds, seconds, minutes, hours and days. Depending on the
-  largest available unit in the format specified with \ref setTimeFormat, any time spans above will
-  be carried in that largest unit. So for example if the format string is "%m:%s" and a tick at
-  coordinate value 7815 (being 2 hours, 10 minutes and 15 seconds) is created, the resulting tick
-  label will show "130:15" (130 minutes, 15 seconds). If the format string is "%h:%m:%s", the hour
-  unit will be used and the label will thus be "02:10:15". Negative times with respect to the axis
-  zero will carry a leading minus sign.
-  
-  The ticker can be created and assigned to an axis like this:
-  \snippet documentation/doc-image-generator/mainwindow.cpp axistickertime-creation
-  
-  Here is an example of a time axis providing time information in days, hours and minutes. Due to
-  the axis range spanning a few days and the wanted tick count (\ref setTickCount), the ticker
-  decided to use tick steps of 12 hours:
-

-  
-  Especially in the case of a log base equal to 10 (the default), it might be desirable to have
-  tick labels in the form of powers of ten without mantissa display. To achieve this, set the
-  number precision (\ref QCPAxis::setNumberPrecision) to zero and the number format (\ref
-  QCPAxis::setNumberFormat) to scientific (exponential) display with beautifully typeset decimal
-  powers, so a format string of <tt>"eb"</tt>. This will result in the following axis tick labels:

-  
-  \a formatCode is a string of one, two or three characters. The first character is identical to
-  the normal format code used by Qt. In short, this means: 'e'/'E' scientific format, 'f' fixed
-  format, 'g'/'G' scientific or fixed, whichever is shorter.
-  
-  The second and third characters are optional and specific to QCustomPlot:\n
-  If the first char was 'e' or 'g', numbers are/might be displayed in the scientific format, e.g.
-  "5.5e9", which is ugly in a plot. So when the second char of \a formatCode is set to 'b' (for
-  "beautiful"), those exponential numbers are formatted in a more natural way, i.e. "5.5
-  [multiplication sign] 10 [superscript] 9". By default, the multiplication sign is a centered dot.
-  If instead a cross should be shown (as is usual in the USA), the third char of \a formatCode can
-  be set to 'c'. The inserted multiplication signs are the UTF-8 characters 215 (0xD7) for the
-  cross and 183 (0xB7) for the dot.
-  
-  Examples for \a formatCode:
-  \li \c g normal format code behaviour. If number is small, fixed format is used, if number is large,
-  normal scientific format is used
-  \li \c gb If number is small, fixed format is used, if number is large, scientific format is used with
-  beautifully typeset decimal powers and a dot as multiplication sign
-  \li \c ebc All numbers are in scientific format with beautifully typeset decimal power and a cross as
-  multiplication sign
-  \li \c fb illegal format code, since fixed format doesn't support (or need) beautifully typeset decimal
-  powers. Format code will be reduced to 'f'.
-  \li \c hello illegal format code, since first char is not 'e', 'E', 'f', 'g' or 'G'. Current format
-  code will not be changed.

-/*! \class QCPScatterStyle
-  \brief Represents the visual appearance of scatter points
-  
-  This class holds information about shape, color and size of scatter points. In plottables like
-  QCPGraph it is used to store how scatter points shall be drawn. For example, \ref
-  QCPGraph::setScatterStyle takes a QCPScatterStyle instance.
-  
-  A scatter style consists of a shape (\ref setShape), a line color (\ref setPen) and possibly a
-  fill (\ref setBrush), if the shape provides a fillable area. Further, the size of the shape can
-  be controlled with \ref setSize.
-
-  \section QCPScatterStyle-defining Specifying a scatter style
-  
-  You can set all these configurations either by calling the respective functions on an instance:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpscatterstyle-creation-1
-  
-  Or you can use one of the various constructors that take different parameter combinations, making
-  it easy to specify a scatter style in a single call, like so:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpscatterstyle-creation-2
-  
-  \section QCPScatterStyle-undefinedpen Leaving the color/pen up to the plottable
-  
-  There are two constructors which leave the pen undefined: \ref QCPScatterStyle() and \ref
-  QCPScatterStyle(ScatterShape shape, double size). If those constructors are used, a call to \ref
-  isPenDefined will return false. It leads to scatter points that inherit the pen from the
-  plottable that uses the scatter style. Thus, if such a scatter style is passed to QCPGraph, the line
-  color of the graph (\ref QCPGraph::setPen) will be used by the scatter points. This makes
-  it very convenient to set up typical scatter settings:
-  
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpscatterstyle-shortcreation
-
-  Notice that it wasn't even necessary to explicitly call a QCPScatterStyle constructor. This works
-  because QCPScatterStyle provides a constructor that can transform a \ref ScatterShape directly
-  into a QCPScatterStyle instance (that's the \ref QCPScatterStyle(ScatterShape shape, double size)
-  constructor with a default for \a size). In those cases, C++ allows directly supplying a \ref
-  ScatterShape, where actually a QCPScatterStyle is expected.
-  
-  \section QCPScatterStyle-custompath-and-pixmap Custom shapes and pixmaps
-  
-  QCPScatterStyle supports drawing custom shapes and arbitrary pixmaps as scatter points.
-
-  For custom shapes, you can provide a QPainterPath with the desired shape to the \ref
-  setCustomPath function or call the constructor that takes a painter path. The scatter shape will
-  automatically be set to \ref ssCustom.
-  
-  For pixmaps, you call \ref setPixmap with the desired QPixmap. Alternatively you can use the
-  constructor that takes a QPixmap. The scatter shape will automatically be set to \ref ssPixmap.
-  Note that \ref setSize does not influence the appearance of the pixmap.
-*/

-/* start documentation of inline functions */

-  
-  Returns whether the scatter shape is \ref ssNone.

-/*! \class QCPSelectionDecorator
-  \brief Controls how a plottable's data selection is drawn
-  
-  Each \ref QCPAbstractPlottable instance has one \ref QCPSelectionDecorator (accessible via \ref
-  QCPAbstractPlottable::selectionDecorator) and uses it when drawing selected segments of its data.
-  
-  The selection decorator controls both pen (\ref setPen) and brush (\ref setBrush), as well as the
-  scatter style (\ref setScatterStyle) if the plottable draws scatters. Since a \ref
-  QCPScatterStyle is itself composed of different properties such as color shape and size, the
-  decorator allows specifying exactly which of those properties shall be used for the selected data
-  point, via \ref setUsedScatterProperties.
-  
-  A \ref QCPSelectionDecorator subclass instance can be passed to a plottable via \ref
-  QCPAbstractPlottable::setSelectionDecorator, allowing greater customizability of the appearance
-  of selected segments.
-  
-  Use \ref copyFrom to easily transfer the settings of one decorator to another one. This is
-  especially useful since plottables take ownership of the passed selection decorator, and thus the
-  same decorator instance can not be passed to multiple plottables.
-  
-  Selection decorators can also themselves perform drawing operations by reimplementing \ref
-  drawDecoration, which is called by the plottable's draw method. The base class \ref
-  QCPSelectionDecorator does not make use of this however. For example, \ref
-  QCPSelectionDecoratorBracket draws brackets around selected data segments.

-/*! \class QCPAbstractPlottable
-  \brief The abstract base class for all data representing objects in a plot.
-
-  It defines a very basic interface like name, pen, brush, visibility etc. Since this class is
-  abstract, it can't be instantiated. Use one of the subclasses or create a subclass yourself to
-  create new ways of displaying data (see "Creating own plottables" below). Plottables that display
-  one-dimensional data (i.e. data points have a single key dimension and one or multiple values at
-  each key) are based off of the template subclass \ref QCPAbstractPlottable1D, see details
-  there.
-  
-  All further specifics are in the subclasses, for example:
-  \li A normal graph with possibly a line and/or scatter points \ref QCPGraph
-  (typically created with \ref QCustomPlot::addGraph)
-  \li A parametric curve: \ref QCPCurve
-  \li A bar chart: \ref QCPBars
-  \li A statistical box plot: \ref QCPStatisticalBox
-  \li A color encoded two-dimensional map: \ref QCPColorMap
-  \li An OHLC/Candlestick chart: \ref QCPFinancial
-  
-  \section plottables-subclassing Creating own plottables
-  
-  Subclassing directly from QCPAbstractPlottable is only recommended if you wish to display
-  two-dimensional data like \ref QCPColorMap, i.e. two logical key dimensions and one (or more)
-  data dimensions. If you want to display data with only one logical key dimension, you should
-  rather derive from \ref QCPAbstractPlottable1D.
-  
-  If subclassing QCPAbstractPlottable directly, these are the pure virtual functions you must
-  implement:
-  \li \ref selectTest
-  \li \ref draw
-  \li \ref drawLegendIcon
-  \li \ref getKeyRange
-  \li \ref getValueRange
-  
-  See the documentation of those functions for what they need to do.
-  
-  For drawing your plot, you can use the \ref coordsToPixels functions to translate a point in plot
-  coordinates to pixel coordinates. This function is quite convenient, because it takes the
-  orientation of the key and value axes into account for you (x and y are swapped when the key axis
-  is vertical and the value axis horizontal). If you are worried about performance (i.e. you need
-  to translate many points in a loop like QCPGraph), you can directly use \ref
-  QCPAxis::coordToPixel. However, you must then take care about the orientation of the axis
-  yourself.
-  
-  Here are some important members you inherit from QCPAbstractPlottable:
-  <table>
-  <tr>
-    <td>QCustomPlot *\b mParentPlot</td>
-    <td>A pointer to the parent QCustomPlot instance. The parent plot is inferred from the axes that are passed in the constructor.</td>
-  </tr><tr>
-    <td>QString \b mName</td>
-    <td>The name of the plottable.</td>
-  </tr><tr>
-    <td>QPen \b mPen</td>
-    <td>The generic pen of the plottable. You should use this pen for the most prominent data representing lines in the plottable
-        (e.g QCPGraph uses this pen for its graph lines and scatters)</td>
-  </tr><tr>
-    <td>QBrush \b mBrush</td>
-    <td>The generic brush of the plottable. You should use this brush for the most prominent fillable structures in the plottable
-        (e.g. QCPGraph uses this brush to control filling under the graph)</td>
-  </tr><tr>
-    <td>QPointer<\ref QCPAxis> \b mKeyAxis, \b mValueAxis</td>
-    <td>The key and value axes this plottable is attached to. Call their QCPAxis::coordToPixel functions to translate coordinates
-        to pixels in either the key or value dimension. Make sure to check whether the pointer is null before using it. If one of
-        the axes is null, don't draw the plottable.</td>
-  </tr><tr>
-    <td>\ref QCPSelectionDecorator \b mSelectionDecorator</td>
-    <td>The currently set selection decorator which specifies how selected data of the plottable shall be drawn and decorated.
-        When drawing your data, you must consult this decorator for the appropriate pen/brush before drawing unselected/selected data segments.
-        Finally, you should call its \ref QCPSelectionDecorator::drawDecoration method at the end of your \ref draw implementation.</td>
-  </tr><tr>
-    <td>\ref QCP::SelectionType \b mSelectable</td>
-    <td>In which composition, if at all, this plottable's data may be selected. Enforcing this setting on the data selection is done
-        by QCPAbstractPlottable automatically.</td>
-  </tr><tr>
-    <td>\ref QCPDataSelection \b mSelection</td>
-    <td>Holds the current selection state of the plottable's data, i.e. the selected data ranges (\ref QCPDataRange).</td>

-/*! \class QCPItemAnchor
-  \brief An anchor of an item to which positions can be attached to.
-  
-  An item (QCPAbstractItem) may have one or more anchors. Unlike QCPItemPosition, an anchor doesn't
-  control anything on its item, but provides a way to tie other items via their positions to the
-  anchor.
-
-  For example, a QCPItemRect is defined by its positions \a topLeft and \a bottomRight.
-  Additionally it has various anchors like \a top, \a topRight or \a bottomLeft etc. So you can
-  attach the \a start (which is a QCPItemPosition) of a QCPItemLine to one of the anchors by
-  calling QCPItemPosition::setParentAnchor on \a start, passing the wanted anchor of the
-  QCPItemRect. This way the start of the line will now always follow the respective anchor location
-  on the rect item.
-  
-  Note that QCPItemPosition derives from QCPItemAnchor, so every position can also serve as an
-  anchor to other positions.
-  
-  To learn how to provide anchors in your own item subclasses, see the subclassing section of the
-  QCPAbstractItem documentation.

-/*! \class QCPItemPosition
-  \brief Manages the position of an item.
-  
-  Every item has at least one public QCPItemPosition member pointer which provides ways to position the
-  item on the QCustomPlot surface. Some items have multiple positions, for example QCPItemRect has two:
-  \a topLeft and \a bottomRight.
-
-  QCPItemPosition has a type (\ref PositionType) that can be set with \ref setType. This type
-  defines how coordinates passed to \ref setCoords are to be interpreted, e.g. as absolute pixel
-  coordinates, as plot coordinates of certain axes, etc. For more advanced plots it is also
-  possible to assign different types per X/Y coordinate of the position (see \ref setTypeX, \ref
-  setTypeY). This way an item could be positioned at a fixed pixel distance from the top in the Y
-  direction, while following a plot coordinate in the X direction.
-
-  A QCPItemPosition may have a parent QCPItemAnchor, see \ref setParentAnchor. This way you can tie
-  multiple items together. If the QCPItemPosition has a parent, its coordinates (\ref setCoords)
-  are considered to be absolute pixels in the reference frame of the parent anchor, where (0, 0)
-  means directly ontop of the parent anchor. For example, You could attach the \a start position of
-  a QCPItemLine to the \a bottom anchor of a QCPItemText to make the starting point of the line
-  always be centered under the text label, no matter where the text is moved to. For more advanced
-  plots, it is possible to assign different parent anchors per X/Y coordinate of the position, see
-  \ref setParentAnchorX, \ref setParentAnchorY. This way an item could follow another item in the X
-  direction but stay at a fixed position in the Y direction. Or even follow item A in X, and item B
-  in Y.
-
-  Note that every QCPItemPosition inherits from QCPItemAnchor and thus can itself be used as parent
-  anchor for other positions.
-
-  To set the apparent pixel position on the QCustomPlot surface directly, use \ref setPixelPosition. This
-  works no matter what type this QCPItemPosition is or what parent-child situation it is in, as \ref
-  setPixelPosition transforms the coordinates appropriately, to make the position appear at the specified
-  pixel values.

-/*! \class QCPAbstractItem
-  \brief The abstract base class for all items in a plot.
-  
-  In QCustomPlot, items are supplemental graphical elements that are neither plottables
-  (QCPAbstractPlottable) nor axes (QCPAxis). While plottables are always tied to two axes and thus
-  plot coordinates, items can also be placed in absolute coordinates independent of any axes. Each
-  specific item has at least one QCPItemPosition member which controls the positioning. Some items
-  are defined by more than one coordinate and thus have two or more QCPItemPosition members (For
-  example, QCPItemRect has \a topLeft and \a bottomRight).
-  
-  This abstract base class defines a very basic interface like visibility and clipping. Since this
-  class is abstract, it can't be instantiated. Use one of the subclasses or create a subclass
-  yourself to create new items.
-  
-  The built-in items are:
-  <table>
-  <tr><td>QCPItemLine</td><td>A line defined by a start and an end point. May have different ending styles on each side (e.g. arrows).</td></tr>
-  <tr><td>QCPItemStraightLine</td><td>A straight line defined by a start and a direction point. Unlike QCPItemLine, the straight line is infinitely long and has no endings.</td></tr>
-  <tr><td>QCPItemCurve</td><td>A curve defined by start, end and two intermediate control points. May have different ending styles on each side (e.g. arrows).</td></tr>
-  <tr><td>QCPItemRect</td><td>A rectangle</td></tr>
-  <tr><td>QCPItemEllipse</td><td>An ellipse</td></tr>
-  <tr><td>QCPItemPixmap</td><td>An arbitrary pixmap</td></tr>
-  <tr><td>QCPItemText</td><td>A text label</td></tr>
-  <tr><td>QCPItemBracket</td><td>A bracket which may be used to reference/highlight certain parts in the plot.</td></tr>
-  <tr><td>QCPItemTracer</td><td>An item that can be attached to a QCPGraph and sticks to its data points, given a key coordinate.</td></tr>
-  </table>
-  
-  \section items-clipping Clipping
-
-  Items are by default clipped to the main axis rect (they are only visible inside the axis rect).
-  To make an item visible outside that axis rect, disable clipping via \ref setClipToAxisRect
-  "setClipToAxisRect(false)".
-
-  On the other hand if you want the item to be clipped to a different axis rect, specify it via
-  \ref setClipAxisRect. This clipAxisRect property of an item is only used for clipping behaviour, and
-  in principle is independent of the coordinate axes the item might be tied to via its position
-  members (\ref QCPItemPosition::setAxes). However, it is common that the axis rect for clipping
-  also contains the axes used for the item positions.
-  
-  \section items-using Using items
-  
-  First you instantiate the item you want to use and add it to the plot:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-1
-  by default, the positions of the item are bound to the x- and y-Axis of the plot. So we can just
-  set the plot coordinates where the line should start/end:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-2
-  If we don't want the line to be positioned in plot coordinates but a different coordinate system,
-  e.g. absolute pixel positions on the QCustomPlot surface, we need to change the position type like this:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-3
-  Then we can set the coordinates, this time in pixels:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-4
-  and make the line visible on the entire QCustomPlot, by disabling clipping to the axis rect:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-5
-  
-  For more advanced plots, it is even possible to set different types and parent anchors per X/Y
-  coordinate of an item position, using for example \ref QCPItemPosition::setTypeX or \ref
-  QCPItemPosition::setParentAnchorX. For details, see the documentation of \ref QCPItemPosition.
-  
-  \section items-subclassing Creating own items
-  
-  To create an own item, you implement a subclass of QCPAbstractItem. These are the pure
-  virtual functions, you must implement:
-  \li \ref selectTest
-  \li \ref draw
-  
-  See the documentation of those functions for what they need to do.
-  
-  \subsection items-positioning Allowing the item to be positioned
-  
-  As mentioned, item positions are represented by QCPItemPosition members. Let's assume the new item shall
-  have only one point as its position (as opposed to two like a rect or multiple like a polygon). You then add
-  a public member of type QCPItemPosition like so:
-  
-  \code QCPItemPosition * const myPosition;\endcode
-  
-  the const makes sure the pointer itself can't be modified from the user of your new item (the QCPItemPosition
-  instance it points to, can be modified, of course).
-  The initialization of this pointer is made easy with the \ref createPosition function. Just assign
-  the return value of this function to each QCPItemPosition in the constructor of your item. \ref createPosition
-  takes a string which is the name of the position, typically this is identical to the variable name.
-  For example, the constructor of QCPItemExample could look like this:
-  
-  \code
-  QCPItemExample::QCPItemExample(QCustomPlot *parentPlot) :
-    QCPAbstractItem(parentPlot),
-    myPosition(createPosition("myPosition"))
-  {
-    // other constructor code
-  }
-  \endcode
-  
-  \subsection items-drawing The draw function
-  
-  To give your item a visual representation, reimplement the \ref draw function and use the passed
-  QCPPainter to draw the item. You can retrieve the item position in pixel coordinates from the
-  position member(s) via \ref QCPItemPosition::pixelPosition.
-
-  To optimize performance you should calculate a bounding rect first (don't forget to take the pen
-  width into account), check whether it intersects the \ref clipRect, and only draw the item at all
-  if this is the case.
-  
-  \subsection items-selection The selectTest function
-  
-  Your implementation of the \ref selectTest function may use the helpers \ref
-  QCPVector2D::distanceSquaredToLine and \ref rectDistance. With these, the implementation of the
-  selection test becomes significantly simpler for most items. See the documentation of \ref
-  selectTest for what the function parameters mean and what the function should return.
-  
-  \subsection anchors Providing anchors
-  
-  Providing anchors (QCPItemAnchor) starts off like adding a position. First you create a public
-  member, e.g.
-  
-  \code QCPItemAnchor * const bottom;\endcode
-
-  and create it in the constructor with the \ref createAnchor function, assigning it a name and an
-  anchor id (an integer enumerating all anchors on the item, you may create an own enum for this).
-  Since anchors can be placed anywhere, relative to the item's position(s), your item needs to
-  provide the position of every anchor with the reimplementation of the \ref anchorPixelPosition(int
-  anchorId) function.
-  
-  In essence the QCPItemAnchor is merely an intermediary that itself asks your item for the pixel
-  position when anything attached to the anchor needs to know the coordinates.

-  respective interaction is enabled, the user may drag axes ranges and zoom with the mouse wheel.
-  For details how to control which axes the user may drag/zoom and in what orientations, see \ref
-  QCPAxisRect::setRangeDrag, \ref QCPAxisRect::setRangeZoom, \ref QCPAxisRect::setRangeDragAxes,
-  \ref QCPAxisRect::setRangeZoomAxes.
-  
-  <b>Plottable data selection</b> is controlled by \ref QCP::iSelectPlottables. If \ref
-  QCP::iSelectPlottables is set, the user may select plottables (graphs, curves, bars,...) and
-  their data by clicking on them or in their vicinity (\ref setSelectionTolerance). Whether the
-  user can actually select a plottable and its data can further be restricted with the \ref
-  QCPAbstractPlottable::setSelectable method on the specific plottable. For details, see the
-  special page about the \ref dataselection "data selection mechanism". To retrieve a list of all
-  currently selected plottables, call \ref selectedPlottables. If you're only interested in
-  QCPGraphs, you may use the convenience function \ref selectedGraphs.
-  
-  <b>Item selection</b> is controlled by \ref QCP::iSelectItems. If \ref QCP::iSelectItems is set, the user
-  may select items (QCPItemLine, QCPItemText,...) by clicking on them or in their vicinity. To find
-  out whether a specific item is selected, call QCPAbstractItem::selected(). To retrieve a list of
-  all currently selected items, call \ref selectedItems.
-  
-  <b>Axis selection</b> is controlled with \ref QCP::iSelectAxes. If \ref QCP::iSelectAxes is set, the user
-  may select parts of the axes by clicking on them. What parts exactly (e.g. Axis base line, tick
-  labels, axis label) are selectable can be controlled via \ref QCPAxis::setSelectableParts for
-  each axis. To retrieve a list of all axes that currently contain selected parts, call \ref
-  selectedAxes. Which parts of an axis are selected, can be retrieved with QCPAxis::selectedParts().
-  
-  <b>Legend selection</b> is controlled with \ref QCP::iSelectLegend. If this is set, the user may
-  select the legend itself or individual items by clicking on them. What parts exactly are
-  selectable can be controlled via \ref QCPLegend::setSelectableParts. To find out whether the
-  legend or any of its child items are selected, check the value of QCPLegend::selectedParts. To
-  find out which child items are selected, call \ref QCPLegend::selectedItems.
-  
-  <b>All other selectable elements</b> The selection of all other selectable objects (e.g.
-  QCPTextElement, or your own layerable subclasses) is controlled with \ref QCP::iSelectOther. If set, the
-  user may select those objects by clicking on them. To find out which are currently selected, you
-  need to check their selected state explicitly.
-  
-  If the selection state has changed by user interaction, the \ref selectionChangedByUser signal is
-  emitted. Each selectable object additionally emits an individual selectionChanged signal whenever
-  their selection state has changed, i.e. not only by user interaction.
-

-  \warning This is still an experimental feature and its performance depends on the system that it

-  might cause context conflicts on some systems.
-  
-  This method allows to enable OpenGL plot rendering, for increased plotting performance of
-  graphically demanding plots (thick lines, translucent fills, etc.).
-
-  If \a enabled is set to true, QCustomPlot will try to initialize OpenGL and, if successful,
-  continue plotting with hardware acceleration. The parameter \a multisampling controls how many
-  samples will be used per pixel, it essentially controls the antialiasing quality. If \a
-  multisampling is set too high for the current graphics hardware, the maximum allowed value will
-  be used.
-
-  You can test whether switching to OpenGL rendering was successful by checking whether the
-  according getter \a QCustomPlot::openGl() returns true. If the OpenGL initialization fails,
-  rendering continues with the regular software rasterizer, and an according qDebug output is
-  generated.
-
-  If switching to OpenGL was successful, this method disables label caching (\ref setPlottingHint
-  "setPlottingHint(QCP::phCacheLabels, false)") and turns on QCustomPlot's antialiasing override
-  for all elements (\ref setAntialiasedElements "setAntialiasedElements(QCP::aeAll)"), leading to a
-  higher quality output. The antialiasing override allows for pixel-grid aligned drawing in the
-  OpenGL paint device. As stated before, in OpenGL rendering the actual antialiasing of the plot is
-  controlled with \a multisampling. If \a enabled is set to false, the antialiasing/label caching
-  settings are restored to what they were before OpenGL was enabled, if they weren't altered in the
-  meantime.
-
-  \note OpenGL support is only enabled if QCustomPlot is compiled with the macro \c QCUSTOMPLOT_USE_OPENGL
-  defined. This define must be set before including the QCustomPlot header both during compilation
-  of the QCustomPlot library as well as when compiling your application. It is best to just include
-  the line <tt>DEFINES += QCUSTOMPLOT_USE_OPENGL</tt> in the respective qmake project files.
-  \note If you are using a Qt version before 5.0, you must also add the module "opengl" to your \c

-  newer OpenGL interface which is already in the "gui" module.

-  the plot, e.g. on the axis ranges or data points of graphs, visible.
-
-  The parameter \a refreshPriority can be used to fine-tune the timing of the replot. For example
-  if your application calls \ref replot very quickly in succession (e.g. multiple independent
-  functions change some aspects of the plot and each wants to make sure the change gets replotted),
-  it is advisable to set \a refreshPriority to \ref QCustomPlot::rpQueuedReplot. This way, the

-  replot with this priority will only cause a single replot, avoiding redundant replots and
-  improving performance.
-
-  Under a few circumstances, QCustomPlot causes a replot by itself. Those are resize events of the
-  QCustomPlot widget and user interactions (object selection and range dragging/zooming).
-
-  Before the replot happens, the signal \ref beforeReplot is emitted. After the replot, \ref
-  afterReplot is emitted. It is safe to mutually connect the replot slot with any of those two
-  signals on two QCustomPlots to make them replot synchronously, it won't cause an infinite
-  recursion.
-
-  If a layer is in mode \ref QCPLayer::lmBuffered (\ref QCPLayer::setMode), it is also possible to
-  replot only that specific layer via \ref QCPLayer::replot. See the documentation there for

-/*! \class QCPColorGradient
-  \brief Defines a color gradient for use with e.g. \ref QCPColorMap
-  
-  This class describes a color gradient which can be used to encode data with color. For example,
-  QCPColorMap and QCPColorScale have \ref QCPColorMap::setGradient "setGradient" methods which
-  take an instance of this class. Colors are set with \ref setColorStopAt(double position, const QColor &color)
-  with a \a position from 0 to 1. In between these defined color positions, the
-  color will be interpolated linearly either in RGB or HSV space, see \ref setColorInterpolation.
-
-  Alternatively, load one of the preset color gradients shown in the image below, with \ref
-  loadPreset, or by directly specifying the preset in the constructor.
-  
-  Apart from red, green and blue components, the gradient also interpolates the alpha values of the
-  configured color stops. This allows to display some portions of the data range as transparent in
-  the plot.
-  
-  \image html QCPColorGradient.png
-  
-  The \ref QCPColorGradient(GradientPreset preset) constructor allows directly converting a \ref
-  GradientPreset to a QCPColorGradient. This means that you can directly pass \ref GradientPreset
-  to all the \a setGradient methods, e.g.:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorgradient-setgradient
-  
-  The total number of levels used in the gradient can be set with \ref setLevelCount. Whether the
-  color gradient shall be applied periodically (wrapping around) to data values that lie outside
-  the data range specified on the plottable instance can be controlled with \ref setPeriodic.

-/*! \class QCPAxisRect
-  \brief Holds multiple axes and arranges them in a rectangular shape.
-  
-  This class represents an axis rect, a rectangular area that is bounded on all sides with an
-  arbitrary number of axes.
-  
-  Initially QCustomPlot has one axis rect, accessible via QCustomPlot::axisRect(). However, the
-  layout system allows to have multiple axis rects, e.g. arranged in a grid layout
-  (QCustomPlot::plotLayout).
-  
-  By default, QCPAxisRect comes with four axes, at bottom, top, left and right. They can be
-  accessed via \ref axis by providing the respective axis type (\ref QCPAxis::AxisType) and index.
-  If you need all axes in the axis rect, use \ref axes. The top and right axes are set to be
-  invisible initially (QCPAxis::setVisible). To add more axes to a side, use \ref addAxis or \ref
-  addAxes. To remove an axis, use \ref removeAxis.
-  
-  The axis rect layerable itself only draws a background pixmap or color, if specified (\ref
-  setBackground). It is placed on the "background" layer initially (see \ref QCPLayer for an
-  explanation of the QCustomPlot layer system). The axes that are held by the axis rect can be
-  placed on other layers, independently of the axis rect.
-  
-  Every axis rect has a child layout of type \ref QCPLayoutInset. It is accessible via \ref
-  insetLayout and can be used to have other layout elements (or even other layouts with multiple
-  elements) hovering inside the axis rect.
-  
-  If an axis rect is clicked and dragged, it processes this by moving certain axis ranges. The
-  behaviour can be controlled with \ref setRangeDrag and \ref setRangeDragAxes. If the mouse wheel
-  is scrolled while the cursor is on the axis rect, certain axes are scaled. This is controllable
-  via \ref setRangeZoom, \ref setRangeZoomAxes and \ref setRangeZoomFactor. These interactions are
-  only enabled if \ref QCustomPlot::setInteractions contains \ref QCP::iRangeDrag and \ref
-  QCP::iRangeZoom.

-  This is the standard legend item for plottables. It displays an icon of the plottable next to the

-  QCPAbstractPlottable::drawLegendIcon), and tries to give an intuitive symbol for the plottable.
-  For example, the QCPGraph draws a centered horizontal line and/or a single scatter point in the

-/*! \class QCPLegend
-  \brief Manages a legend inside a QCustomPlot.
-
-  A legend is a small box somewhere in the plot which lists plottables with their name and icon.
-
-  A legend is populated with legend items by calling \ref QCPAbstractPlottable::addToLegend on the
-  plottable, for which a legend item shall be created. In the case of the main legend (\ref
-  QCustomPlot::legend), simply adding plottables to the plot while \ref
-  QCustomPlot::setAutoAddPlottableToLegend is set to true (the default) creates corresponding
-  legend items. The legend item associated with a certain plottable can be removed with \ref
-  QCPAbstractPlottable::removeFromLegend. However, QCPLegend also offers an interface to add and
-  manipulate legend items directly: \ref item, \ref itemWithPlottable, \ref itemCount, \ref
-  addItem, \ref removeItem, etc.
-
-  Since \ref QCPLegend derives from \ref QCPLayoutGrid, it can be placed in any position a \ref
-  QCPLayoutElement may be positioned. The legend items are themselves \ref QCPLayoutElement
-  "QCPLayoutElements" which are placed in the grid layout of the legend. \ref QCPLegend only adds
-  an interface specialized for handling child elements of type \ref QCPAbstractLegendItem, as
-  mentioned above. In principle, any other layout elements may also be added to a legend via the
-  normal \ref QCPLayoutGrid interface. See the special page about \link thelayoutsystem The Layout
-  System\endlink for examples on how to add other elements to the legend and move it outside the axis
-  rect.
-
-  Use the methods \ref setFillOrder and \ref setWrap inherited from \ref QCPLayoutGrid to control
-  in which order (column first or row first) the legend is filled up when calling \ref addItem, and
-  at which column or row wrapping occurs.
-
-  By default, every QCustomPlot has one legend (\ref QCustomPlot::legend) which is placed in the
-  inset layout of the main axis rect (\ref QCPAxisRect::insetLayout). To move the legend to another
-  position inside the axis rect, use the methods of the \ref QCPLayoutInset. To move the legend
-  outside of the axis rect, place it anywhere else with the \ref QCPLayout/\ref QCPLayoutElement
-  interface.

-/*! \class QCPColorScale
-  \brief A color scale for use with color coding data such as QCPColorMap
-  
-  This layout element can be placed on the plot to correlate a color gradient with data values. It
-  is usually used in combination with one or multiple \ref QCPColorMap "QCPColorMaps".
-
-  \image html QCPColorScale.png
-  
-  The color scale can be either horizontal or vertical, as shown in the image above. The
-  orientation and the side where the numbers appear is controlled with \ref setType.
-  
-  Use \ref QCPColorMap::setColorScale to connect a color map with a color scale. Once they are
-  connected, they share their gradient, data range and data scale type (\ref setGradient, \ref
-  setDataRange, \ref setDataScaleType). Multiple color maps may be associated with a single color
-  scale, to make them all synchronize these properties.
-  
-  To have finer control over the number display and axis behaviour, you can directly access the
-  \ref axis. See the documentation of QCPAxis for details about configuring axes. For example, if
-  you want to change the number of automatically generated ticks, call
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorscale-tickcount
-  
-  Placing a color scale next to the main axis rect works like with any other layout element:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorscale-creation
-  In this case we have placed it to the right of the default axis rect, so it wasn't necessary to
-  call \ref setType, since \ref QCPAxis::atRight is already the default. The text next to the color
-  scale can be set with \ref setLabel.
-  
-  For optimum appearance (like in the image above), it may be desirable to line up the axis rect and
-  the borders of the color scale. Use a \ref QCPMarginGroup to achieve this:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorscale-margingroup
-  
-  Color scales are initialized with a non-zero minimum top and bottom margin (\ref
-  setMinimumMargins), because vertical color scales are most common and the minimum top/bottom
-  margin makes sure it keeps some distance to the top/bottom widget border. So if you change to a
-  horizontal color scale by setting \ref setType to \ref QCPAxis::atBottom or \ref QCPAxis::atTop, you
-  might want to also change the minimum margins accordingly, e.g. <tt>setMinimumMargins(QMargins(6, 0, 6, 0))</tt>.

-/*! \fn QCPAxis *QCPColorScale::axis() const
-  
-  Returns the internal \ref QCPAxis instance of this color scale. You can access it to alter the
-  appearance and behaviour of the axis. \ref QCPColorScale duplicates some properties in its
-  interface for convenience. Those are \ref setDataRange (\ref QCPAxis::setRange), \ref
-  setDataScaleType (\ref QCPAxis::setScaleType), and the method \ref setLabel (\ref
-  QCPAxis::setLabel). As they each are connected, it does not matter whether you use the method on
-  the QCPColorScale or on its QCPAxis.
-  
-  If the type of the color scale is changed with \ref setType, the axis returned by this method
-  will change, too, to either the left, right, bottom or top axis, depending on which type was set.

-/*! \class QCPGraph
-  \brief A plottable representing a graph in a plot.
-
-  \image html QCPGraph.png
-  
-  Usually you create new graphs by calling QCustomPlot::addGraph. The resulting instance can be
-  accessed via QCustomPlot::graph.
-
-  To plot data, assign it with the \ref setData or \ref addData functions. Alternatively, you can
-  also access and modify the data via the \ref data method, which returns a pointer to the internal
-  \ref QCPGraphDataContainer.
-  
-  Graphs are used to display single-valued data. Single-valued means that there should only be one
-  data point per unique key coordinate. In other words, the graph can't have \a loops. If you do
-  want to plot non-single-valued curves, rather use the QCPCurve plottable.
-  
-  Gaps in the graph line can be created by adding data points with NaN as value
-  (<tt>qQNaN()</tt> or <tt>std::numeric_limits<double>::quiet_NaN()</tt>) in between the two data points that shall be
-  separated.
-  
-  \section qcpgraph-appearance Changing the appearance
-  
-  The appearance of the graph is mainly determined by the line style, scatter style, brush and pen
-  of the graph (\ref setLineStyle, \ref setScatterStyle, \ref setBrush, \ref setPen).
-  
-  \subsection filling Filling under or between graphs
-  
-  QCPGraph knows two types of fills: Normal graph fills towards the zero-value-line parallel to
-  the key axis of the graph, and fills between two graphs, called channel fills. To enable a fill,
-  just set a brush with \ref setBrush which is neither Qt::NoBrush nor fully transparent.
-  
-  By default, a normal fill towards the zero-value-line will be drawn. To set up a channel fill
-  between this graph and another one, call \ref setChannelFillGraph with the other graph as
-  parameter.

-  sampling technique can drastically improve the replot performance for graphs with a larger number
-  of points (e.g. above 10,000), without notably changing the appearance of the graph.
-  
-  By default, adaptive sampling is enabled. Even if enabled, QCustomPlot decides whether adaptive
-  sampling shall actually be used on a per-graph basis. So leaving adaptive sampling enabled has no
-  disadvantage in almost all cases.
-  
-  \image html adaptive-sampling-line.png "A line plot of 500,000 points without and with adaptive sampling"
-  
-  As can be seen, line plots experience no visual degradation from adaptive sampling. Outliers are
-  reproduced reliably, as well as the overall shape of the data set. The replot time reduces
-  dramatically though. This allows QCustomPlot to display large amounts of data in realtime.
-  
-  \image html adaptive-sampling-scatter.png "A scatter plot of 100,000 points without and with adaptive sampling"
-  
-  Care must be taken when using high-density scatter plots in combination with adaptive sampling.
-  The adaptive sampling algorithm treats scatter plots more carefully than line plots which still
-  gives a significant reduction of replot times, but not quite as much as for line plots. This is
-  because scatter plots inherently need more data points to be preserved in order to still resemble
-  the original, non-adaptive-sampling plot. As shown above, the results still aren't quite
-  identical, as banding occurs for the outer data points. This is in fact intentional, such that
-  the boundaries of the data cloud stay visible to the viewer. How strong the banding appears,
-  depends on the point density, i.e. the number of points in the plot.
-  
-  For some situations with scatter plots it might thus be desirable to manually turn adaptive
-  sampling off. For example, when saving the plot to disk. This can be achieved by setting \a
-  enabled to false before issuing a command like \ref QCustomPlot::savePng, and setting \a enabled

-/*! \class QCPCurve
-  \brief A plottable representing a parametric curve in a plot.
-  
-  \image html QCPCurve.png
-  
-  Unlike QCPGraph, plottables of this type may have multiple points with the same key coordinate,
-  so their visual representation can have \a loops. This is realized by introducing a third
-  coordinate \a t, which defines the order of the points described by the other two coordinates \a
-  x and \a y.
-
-  To plot data, assign it with the \ref setData or \ref addData functions. Alternatively, you can
-  also access and modify the curve's data via the \ref data method, which returns a pointer to the
-  internal \ref QCPCurveDataContainer.
-  
-  Gaps in the curve can be created by adding data points with NaN as key and value
-  (<tt>qQNaN()</tt> or <tt>std::numeric_limits<double>::quiet_NaN()</tt>) in between the two data points that shall be
-  separated.
-  
-  \section qcpcurve-appearance Changing the appearance
-  
-  The appearance of the curve is determined by the pen and the brush (\ref setPen, \ref setBrush).
-  
-  \section qcpcurve-usage Usage
-  
-  Like all data representing objects in QCustomPlot, the QCPCurve is a plottable
-  (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
-  (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
-  
-  Usually, you first create an instance:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcurve-creation-1
-  which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot instance takes
-  ownership of the plottable, so do not delete it manually but use QCustomPlot::removePlottable() instead.
-  The newly created plottable can be modified, e.g.:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcurve-creation-2

-  printed to the debug output (qDebug), the construction is not aborted, though.

-  The created QCPCurve is automatically registered with the QCustomPlot instance inferred from \a

-  This function is part of the curve optimization algorithm of \ref getCurveLines.
-  
-  In situations where a single segment skips over multiple regions it might become necessary to add
-  extra points at the corners of region 5 (see \ref getRegion) such that the optimized segment
-  doesn't unintentionally cut through the visible area of the axis rect and create plot artifacts.
-  This method provides these points that must be added, assuming the original segment doesn't
-  start, end, or traverse region 5. (Corner points where region 5 is traversed are calculated by
-  \ref getTraverseCornerPoints.)
-  
-  For example, consider a segment which directly goes from region 4 to 2 but originally is far out
-  to the top left such that it doesn't cross region 5. Naively optimizing these points by
-  projecting them on the top and left borders of region 5 will create a segment that surely crosses
-  5, creating a visual artifact in the plot. This method prevents this by providing extra points at
-  the top left corner, making the optimized curve correctly pass from region 4 to 1 to 2 without
-  traversing 5.

-  This function is part of the curve optimization algorithm of \ref getCurveLines.
-  
-  This method assumes that the \ref getTraverse test has returned true, so the segment definitely
-  traverses the visible region 5 when going from \a prevRegion to \a currentRegion.
-  
-  In certain situations it is not sufficient to merely generate the entry and exit points of the
-  segment into/out of region 5, as \ref getTraverse provides. It may happen that a single segment, in
-  addition to traversing region 5, skips another region outside of region 5, which makes it
-  necessary to add an optimized corner point there (very similar to the job \ref
-  getOptimizedCornerPoints does for segments that are completely in outside regions and don't
-  traverse 5).
-  
-  As an example, consider a segment going from region 1 to region 6, traversing the lower left
-  corner of region 5. In this configuration, the segment additionally crosses the border between
-  region 1 and 2 before entering region 5. This makes it necessary to add an additional point in
-  the top left corner, before adding the optimized traverse points. So in this case, the output
-  parameter \a beforeTraverse will contain the top left corner point, and \a afterTraverse will be
-  empty.
-  
-  In some cases, such as when going from region 1 to 9, it may even be necessary to add additional
-  corner points before and after the traverse. Then both \a beforeTraverse and \a afterTraverse
-  return the respective corner points.

-  \brief Groups multiple QCPBars together so they appear side by side
-  
-  \image html QCPBarsGroup.png
-  
-  When showing multiple QCPBars in one plot which have bars at identical keys, it may be desirable
-  to have them appearing next to each other at each key. This is what adding the respective QCPBars
-  plottables to a QCPBarsGroup achieves. (An alternative approach is to stack them on top of each
-  other, see \ref QCPBars::moveAbove.)
-  
-  \section qcpbarsgroup-usage Usage
-  
-  To add a QCPBars plottable to the group, create a new group and then add the respective bars
-  intances:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpbarsgroup-creation
-  Alternatively to appending to the group like shown above, you can also set the group on the
-  QCPBars plottable via \ref QCPBars::setBarsGroup.
-  
-  The spacing between the bars can be configured via \ref setSpacingType and \ref setSpacing. The
-  bars in this group appear in the plot in the order they were appended. To insert a bars plottable
-  at a certain index position, or to reposition a bars plottable which is already in the group, use
-  \ref insert.
-  
-  To remove specific bars from the group, use either \ref remove or call \ref
-  QCPBars::setBarsGroup "QCPBars::setBarsGroup(0)" on the respective bars plottable.
-  
-  To clear the entire group, call \ref clear, or simply delete the group.

-  \brief A plottable representing a bar chart in a plot.
-
-  \image html QCPBars.png
-  
-  To plot data, assign it with the \ref setData or \ref addData functions.
-  
-  \section qcpbars-appearance Changing the appearance
-  
-  The appearance of the bars is determined by the pen and the brush (\ref setPen, \ref setBrush).
-  The width of the individual bars can be controlled with \ref setWidthType and \ref setWidth.
-  
-  Bar charts are stackable. This means, two QCPBars plottables can be placed on top of each other
-  (see \ref QCPBars::moveAbove). So when two bars are at the same key position, they will appear
-  stacked.
-  
-  If you would like to group multiple QCPBars plottables together so they appear side by side as
-  shown below, use QCPBarsGroup.
-  
-  \image html QCPBarsGroup.png
-  
-  \section qcpbars-usage Usage
-  
-  Like all data representing objects in QCustomPlot, the QCPBars is a plottable
-  (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
-  (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
-  
-  Usually, you first create an instance:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpbars-creation-1
-  which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot instance takes
-  ownership of the plottable, so do not delete it manually but use QCustomPlot::removePlottable() instead.
-  The newly created plottable can be modified, e.g.:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpbars-creation-2

-  use it to directly manipulate the data, which may be more convenient and faster than using the
-  regular \ref setData or \ref addData methods.

-/*! \class QCPStatisticalBox
-  \brief A plottable representing a single statistical box in a plot.
-
-  \image html QCPStatisticalBox.png
-  
-  To plot data, assign it with the \ref setData or \ref addData functions. Alternatively, you can
-  also access and modify the data via the \ref data method, which returns a pointer to the internal
-  \ref QCPStatisticalBoxDataContainer.
-  
-  Additionally each data point can itself have a list of outliers, drawn as scatter points at the
-  key coordinate of the respective statistical box data point. They can either be set by using the
-  respective \ref addData(double,double,double,double,double,double,const QVector<double>&)
-  "addData" method or accessing the individual data points through \ref data, and setting the
-  <tt>QVector<double> outliers</tt> of the data points directly.
-  
-  \section qcpstatisticalbox-appearance Changing the appearance
-  
-  The appearance of each data point box, ranging from the lower to the upper quartile, is
-  controlled via \ref setPen and \ref setBrush. You may change the width of the boxes with \ref
-  setWidth in plot coordinates.
-
-  Each data point's visual representation also consists of two whiskers. Whiskers are the lines
-  which reach from the upper quartile to the maximum, and from the lower quartile to the minimum.
-  The appearance of the whiskers can be modified with: \ref setWhiskerPen, \ref setWhiskerBarPen,
-  \ref setWhiskerWidth. The whisker width is the width of the bar perpendicular to the whisker at
-  the top (for maximum) and bottom (for minimum). If the whisker pen is changed, make sure to set
-  the \c capStyle to \c Qt::FlatCap. Otherwise the backbone line might exceed the whisker bars by a
-  few pixels due to the pen cap being not perfectly flat.
-  
-  The median indicator line inside the box has its own pen, \ref setMedianPen.
-  
-  The outlier data points are drawn as normal scatter points. Their look can be controlled with
-  \ref setOutlierStyle
-  
-  \section qcpstatisticalbox-usage Usage
-  
-  Like all data representing objects in QCustomPlot, the QCPStatisticalBox is a plottable
-  (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
-  (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
-  
-  Usually, you first create an instance:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpstatisticalbox-creation-1
-  which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot instance takes
-  ownership of the plottable, so do not delete it manually but use QCustomPlot::removePlottable() instead.
-  The newly created plottable can be modified, e.g.:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpstatisticalbox-creation-2

-/*! \class QCPColorMapData
-  \brief Holds the two-dimensional data of a QCPColorMap plottable.
-  
-  This class is a data storage for \ref QCPColorMap. It holds a two-dimensional array, which \ref
-  QCPColorMap then displays as a 2D image in the plot, where the array values are represented by a
-  color, depending on the value.
-  
-  The size of the array can be controlled via \ref setSize (or \ref setKeySize, \ref setValueSize).
-  Which plot coordinates these cells correspond to can be configured with \ref setRange (or \ref
-  setKeyRange, \ref setValueRange).
-  
-  The data cells can be accessed in two ways: They can be directly addressed by an integer index
-  with \ref setCell. This is the fastest method. Alternatively, they can be addressed by their plot
-  coordinate with \ref setData. plot coordinate to cell index transformations and vice versa are
-  provided by the functions \ref coordToCell and \ref cellToCoord.
-  
-  A \ref QCPColorMapData also holds an on-demand two-dimensional array of alpha values which (if
-  allocated) has the same size as the data map. It can be accessed via \ref setAlpha, \ref
-  fillAlpha and \ref clearAlpha. The memory for the alpha map is only allocated if needed, i.e. on
-  the first call of \ref setAlpha. \ref clearAlpha restores full opacity and frees the alpha map.
-  
-  This class also buffers the minimum and maximum values that are in the data set, to provide
-  QCPColorMap::rescaleDataRange with the necessary information quickly. Setting a cell to a value
-  that is greater than the current maximum increases this maximum to the new value. However,
-  setting the cell that currently holds the maximum value to a smaller value doesn't decrease the
-  maximum again, because finding the true new maximum would require going through the entire data
-  array, which might be time consuming. The same holds for the data minimum. This functionality is
-  given by \ref recalculateDataBounds, such that you can decide when it is sensible to find the
-  true current minimum and maximum. The method QCPColorMap::rescaleDataRange offers a convenience
-  parameter \a recalculateDataBounds which may be set to true to automatically call \ref
-  recalculateDataBounds internally.

-/*! \class QCPColorMap
-  \brief A plottable representing a two-dimensional color map in a plot.
-
-  \image html QCPColorMap.png
-  
-  The data is stored in the class \ref QCPColorMapData, which can be accessed via the data()
-  method.
-  
-  A color map has three dimensions to represent a data point: The \a key dimension, the \a value
-  dimension and the \a data dimension. As with other plottables such as graphs, \a key and \a value
-  correspond to two orthogonal axes on the QCustomPlot surface that you specify in the QCPColorMap
-  constructor. The \a data dimension however is encoded as the color of the point at (\a key, \a
-  value).
-
-  Set the number of points (or \a cells) in the key/value dimension via \ref
-  QCPColorMapData::setSize. The plot coordinate range over which these points will be displayed is
-  specified via \ref QCPColorMapData::setRange. The first cell will be centered on the lower range
-  boundary and the last cell will be centered on the upper range boundary. The data can be set by
-  either accessing the cells directly with QCPColorMapData::setCell or by addressing the cells via
-  their plot coordinates with \ref QCPColorMapData::setData. If possible, you should prefer
-  setCell, since it doesn't need to do any coordinate transformation and thus performs a bit
-  better.
-  
-  The cell with index (0, 0) is at the bottom left, if the color map uses normal (i.e. not reversed)
-  key and value axes.
-  
-  To show the user which colors correspond to which \a data values, a \ref QCPColorScale is
-  typically placed to the right of the axis rect. See the documentation there for details on how to
-  add and use a color scale.
-  
-  \section qcpcolormap-appearance Changing the appearance
-  
-  The central part of the appearance is the color gradient, which can be specified via \ref
-  setGradient. See the documentation of \ref QCPColorGradient for details on configuring a color
-  gradient.
-  
-  The \a data range that is mapped to the colors of the gradient can be specified with \ref
-  setDataRange. To make the data range encompass the whole data set minimum to maximum, call \ref
-  rescaleDataRange.
-  
-  \section qcpcolormap-transparency Transparency
-  
-  Transparency in color maps can be achieved by two mechanisms. On one hand, you can specify alpha
-  values for color stops of the \ref QCPColorGradient, via the regular QColor interface. This will
-  cause the color map data which gets mapped to colors around those color stops to appear with the
-  accordingly interpolated transparency.
-  
-  On the other hand you can also directly apply an alpha value to each cell independent of its
-  data, by using the alpha map feature of \ref QCPColorMapData. The relevant methods are \ref
-  QCPColorMapData::setAlpha, QCPColorMapData::fillAlpha and \ref QCPColorMapData::clearAlpha().
-  
-  The two transparencies will be joined together in the plot and otherwise not interfere with each
-  other. They are mixed in a multiplicative matter, so an alpha of e.g. 50% (128/255) in both modes
-  simultaneously, will result in a total transparency of 25% (64/255).
-  
-  \section qcpcolormap-usage Usage
-  
-  Like all data representing objects in QCustomPlot, the QCPColorMap is a plottable
-  (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
-  (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
-  
-  Usually, you first create an instance:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolormap-creation-1
-  which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot instance takes
-  ownership of the plottable, so do not delete it manually but use QCustomPlot::removePlottable() instead.
-  The newly created plottable can be modified, e.g.:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolormap-creation-2
-  
-  \note The QCPColorMap always displays the data at equal key/value intervals, even if the key or
-  value axis is set to a logarithmic scaling. If you want to use QCPColorMap with logarithmic axes,
-  you shouldn't use the \ref QCPColorMapData::setData method as it uses a linear transformation to
-  determine the cell index. Rather directly access the cell index with \ref
-  QCPColorMapData::setCell.

-/*! \class QCPFinancial
-  \brief A plottable representing a financial stock chart
-
-  \image html QCPFinancial.png
-
-  This plottable represents time series data binned to certain intervals, mainly used for stock
-  charts. The two common representations OHLC (Open-High-Low-Close) bars and Candlesticks can be
-  set via \ref setChartStyle.
-
-  The data is passed via \ref setData as a set of open/high/low/close values at certain keys
-  (typically times). This means the data must be already binned appropriately. If data is only
-  available as a series of values (e.g. \a price against \a time), you can use the static
-  convenience function \ref timeSeriesToOhlc to generate binned OHLC-data which can then be passed
-  to \ref setData.
-
-  The width of the OHLC bars/candlesticks can be controlled with \ref setWidth and \ref
-  setWidthType. A typical choice is to set the width type to \ref wtPlotCoords (the default) and
-  the width to (or slightly less than) one time bin interval width.
-
-  \section qcpfinancial-appearance Changing the appearance
-
-  Charts can be either single- or two-colored (\ref setTwoColored). If set to be single-colored,
-  lines are drawn with the plottable's pen (\ref setPen) and fills with the brush (\ref setBrush).
-
-  If set to two-colored, positive changes of the value during an interval (\a close >= \a open) are
-  represented with a different pen and brush than negative changes (\a close < \a open). These can
-  be configured with \ref setPenPositive, \ref setPenNegative, \ref setBrushPositive, and \ref
-  setBrushNegative. In two-colored mode, the normal plottable pen/brush is ignored. Upon selection
-  however, the normal selected pen/brush (provided by the \ref selectionDecorator) is used,
-  irrespective of whether the chart is single- or two-colored.
-
-  \section qcpfinancial-usage Usage
-
-  Like all data representing objects in QCustomPlot, the QCPFinancial is a plottable
-  (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
-  (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
-
-  Usually, you first create an instance:
-
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpfinancial-creation-1
-  which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot
-  instance takes ownership of the plottable, so do not delete it manually but use
-  QCustomPlot::removePlottable() instead. The newly created plottable can be modified, e.g.:
-
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpfinancial-creation-2
-  Here we have used the static helper method \ref timeSeriesToOhlc, to turn a time-price data
-  series into a 24-hour binned open-high-low-close data series as QCPFinancial uses.

-/*! \fn QCPFinancialDataContainer *QCPFinancial::data() const
-  
-  Returns a pointer to the internal data storage of type \ref QCPFinancialDataContainer. You may
-  use it to directly manipulate the data, which may be more convenient and faster than using the
-  regular \ref setData or \ref addData methods, in certain situations.

-  printed to the debug output (qDebug), the construction is not aborted, though.

-  \brief A plottable that adds a set of error bars to other plottables.
-
-  \image html QCPErrorBars.png
-
-  The \ref QCPErrorBars plottable can be attached to other one-dimensional plottables (e.g. \ref
-  QCPGraph, \ref QCPCurve, \ref QCPBars, etc.) and equips them with error bars.
-
-  Use \ref setDataPlottable to define for which plottable the \ref QCPErrorBars shall display the
-  error bars. The orientation of the error bars can be controlled with \ref setErrorType.
-
-  By using \ref setData, you can supply the actual error data, either as symmetric error or
-  plus/minus asymmetric errors. \ref QCPErrorBars only stores the error data. The absolute
-  key/value position of each error bar will be adopted from the configured data plottable. The
-  error data of the \ref QCPErrorBars are associated one-to-one via their index to the data points
-  of the data plottable. You can directly access and manipulate the error bar data via \ref data.
-
-  Set either of the plus/minus errors to NaN (<tt>qQNaN()</tt> or
-  <tt>std::numeric_limits<double>::quiet_NaN()</tt>) to not show the respective error bar on the data point at
-  that index.
-
-  \section qcperrorbars-appearance Changing the appearance
-
-  The appearance of the error bars is defined by the pen (\ref setPen), and the width of the
-  whiskers (\ref setWhiskerWidth). Further, the error bar backbones may leave a gap around the data
-  point center to prevent that error bars are drawn too close to or even through scatter points.
-  This gap size can be controlled via \ref setSymbolGap.

-/*! \class QCPItemTracer
-  \brief Item that sticks to QCPGraph data points
-
-  \image html QCPItemTracer.png "Tracer example. Blue dotted circles are anchors, solid blue discs are positions."
-
-  The tracer can be connected with a QCPGraph via \ref setGraph. Then it will automatically adopt
-  the coordinate axes of the graph and update its \a position to be on the graph's data. This means
-  the key stays controllable via \ref setGraphKey, but the value will follow the graph data. If a
-  QCPGraph is connected, note that setting the coordinates of the tracer item directly via \a
-  position will have no effect because they will be overriden in the next redraw (this is when the
-  coordinate update happens).
-  
-  If the specified key in \ref setGraphKey is outside the key bounds of the graph, the tracer will
-  stay at the corresponding end of the graph.
-  
-  With \ref setInterpolating you may specify whether the tracer may only stay exactly on data
-  points or whether it interpolates data points linearly, if given a key that lies between two data
-  points of the graph.
-  
-  The tracer has different visual styles, see \ref setStyle. It is also possible to make the tracer
-  have no own visual appearance (set the style to \ref tsNone), and just connect other item
-  positions to the tracer \a position (used as an anchor) via \ref
-  QCPItemPosition::setParentAnchor.
-  
-  \note The tracer position is only automatically updated upon redraws. So when the data of the
-  graph changes and immediately afterwards (without a redraw) the position coordinates of the
-  tracer are retrieved, they will not reflect the updated data of the graph. In this case \ref
-  updatePosition must be called manually, prior to reading the tracer coordinates.

-/*! \class QCPItemBracket
-  \brief A bracket for referencing/highlighting certain parts in the plot.
-
-  \image html QCPItemBracket.png "Bracket example. Blue dotted circles are anchors, solid blue discs are positions."
-
-  It has two positions, \a left and \a right, which define the span of the bracket. If \a left is
-  actually farther to the left than \a right, the bracket is opened to the bottom, as shown in the
-  example image.
-  
-  The bracket supports multiple styles via \ref setStyle. The length, i.e. how far the bracket
-  stretches away from the embraced span, can be controlled with \ref setLength.
-  
-  \image html QCPItemBracket-length.png
-  <center>Demonstrating the effect of different values for \ref setLength, for styles \ref
-  bsCalligraphic and \ref bsSquare. Anchors and positions are displayed for reference.</center>
-  
-  It provides an anchor \a center, to allow connection of other items, e.g. an arrow (QCPItemLine
-  or QCPItemCurve) or a text label (QCPItemText), to the bracket.

+  \brief The abstract base class for paint buffers, which define the rendering backend
+
+  This abstract base class defines the basic interface that a paint buffer needs to provide in
+  order to be usable by QCustomPlot.
+
+  A paint buffer manages both a surface to draw onto, and the matching paint device. The size of
+  the surface can be changed via \ref setSize. External classes (\ref QCustomPlot and \ref
+  QCPLayer) request a painter via \ref startPainting and then perform the draw calls. Once the
+  painting is complete, \ref donePainting is called, so the paint buffer implementation can do
+  clean up if necessary. Before rendering a frame, each paint buffer is usually filled with a color
+  using \ref clear (usually the color is \c Qt::transparent), to remove the contents of the
+  previous frame.
+
+  The simplest paint buffer implementation is \ref QCPPaintBufferPixmap which allows regular
+  software rendering via the raster engine. Hardware accelerated rendering via pixel buffers and
+  frame buffer objects is provided by \ref QCPPaintBufferGlPbuffer and \ref QCPPaintBufferGlFbo.

+/*! \class QCPLayer
+  \brief A layer that may contain objects, to control the rendering order
+
+  The Layering system of QCustomPlot is the mechanism to control the rendering order of the
+  elements inside the plot.
+
+  It is based on the two classes QCPLayer and QCPLayerable. QCustomPlot holds an ordered list of
+  one or more instances of QCPLayer (see QCustomPlot::addLayer, QCustomPlot::layer,
+  QCustomPlot::moveLayer, etc.). When replotting, QCustomPlot goes through the list of layers
+  bottom to top and successively draws the layerables of the layers into the paint buffer(s).
+
+  A QCPLayer contains an ordered list of QCPLayerable instances. QCPLayerable is an abstract base
+  class from which almost all visible objects derive, like axes, grids, graphs, items, etc.
+
+  \section qcplayer-defaultlayers Default layers
+
+  Initially, QCustomPlot has six layers: "background", "grid", "main", "axes", "legend" and
+  "overlay" (in that order). On top is the "overlay" layer, which only contains the QCustomPlot's
+  selection rect (\ref QCustomPlot::selectionRect). The next two layers "axes" and "legend" contain
+  the default axes and legend, so they will be drawn above plottables. In the middle, there is the
+  "main" layer. It is initially empty and set as the current layer (see
+  QCustomPlot::setCurrentLayer). This means, all new plottables, items etc. are created on this
+  layer by default. Then comes the "grid" layer which contains the QCPGrid instances (which belong
+  tightly to QCPAxis, see \ref QCPAxis::grid). The Axis rect background shall be drawn behind
+  everything else, thus the default QCPAxisRect instance is placed on the "background" layer. Of
+  course, the layer affiliation of the individual objects can be changed as required (\ref
+  QCPLayerable::setLayer).
+
+  \section qcplayer-ordering Controlling the rendering order via layers
+
+  Controlling the ordering of layerables in the plot is easy: Create a new layer in the position

+  
+  This function applies the default antialiasing setting to the specified \a painter, using the
+  function \ref applyAntialiasingHint. It is the antialiasing state the painter is put in, when
+  \ref draw is called on the layerable. If the layerable has multiple entities whose antialiasing
+  setting may be specified individually, this function should set the antialiasing state of the
+  most prominent entity. In this case however, the \ref draw function usually calls the specialized
+  versions of this function before drawing each entity, effectively overriding the setting of the
+  default antialiasing hint.
+  
+  <b>First example:</b> QCPGraph has multiple entities that have an antialiasing setting: The graph
+  line, fills and scatters. Those can be configured via QCPGraph::setAntialiased,
+  QCPGraph::setAntialiasedFill and QCPGraph::setAntialiasedScatters. Consequently, there isn't only
+  the QCPGraph::applyDefaultAntialiasingHint function (which corresponds to the graph line's
+  antialiasing), but specialized ones like QCPGraph::applyFillAntialiasingHint and
+  QCPGraph::applyScattersAntialiasingHint. So before drawing one of those entities, QCPGraph::draw
+  calls the respective specialized applyAntialiasingHint function.
+  
+  <b>Second example:</b> QCPItemLine consists only of a line so there is only one antialiasing
+  setting which can be controlled with QCPItemLine::setAntialiased. (This function is inherited by
+  all layerables. The specialized functions, as seen on QCPGraph, must be added explicitly to the
+  respective layerable subclass.) Consequently it only has the normal
+  QCPItemLine::applyDefaultAntialiasingHint. The \ref QCPItemLine::draw function doesn't need to
+  care about setting any antialiasing states, because the default antialiasing hint is already set
+  on the painter when the \ref draw function is called, and that's the state it wants to draw the

+  This event is called when the layerable shall be selected, as a consequence of a click by the

+  implementation does nothing.
+  
+  \a event is the mouse event that caused the selection. \a additive indicates, whether the user
+  was holding the multi-select-modifier while performing the selection (see \ref
+  QCustomPlot::setMultiSelectModifier). if \a additive is true, the selection state must be toggled
+  (i.e. become selected when unselected and unselected when selected).
+  
+  Every selectEvent is preceded by a call to \ref selectTest, which has returned positively (i.e.
+  returned a value greater than 0 and less than the selection tolerance of the parent QCustomPlot).
+  The \a details data you output from \ref selectTest is fed back via \a details here. You may
+  use it to transport any kind of information from the selectTest to the possibly subsequent
+  selectEvent. Usually \a details is used to transfer which part was clicked, if it is a layerable
+  that has multiple individually selectable parts (like QCPAxis). This way selectEvent doesn't need
+  to do the calculation again to find out which part was actually clicked.
+  
+  \a selectionStateChanged is an output parameter. If the pointer is non-null, this function must
+  set the value either to true or false, depending on whether the selection state of this layerable
+  was actually changed. For layerables that only are selectable as a whole and not in parts, this
+  is simple: if \a additive is true, \a selectionStateChanged must also be set to true, because the
+  selection toggles. If \a additive is false, \a selectionStateChanged is only set to true, if the
+  layerable was previously unselected and now is switched to the selected state.

+  the data range, similarly to the nomenclature used in standard iterators.
+  
+  Data Ranges are not bound to a certain plottable, thus they can be freely exchanged, created and
+  modified. If a non-contiguous data set shall be described, the class \ref QCPDataSelection is
+  used, which holds and manages multiple instances of \ref QCPDataRange. In most situations, \ref
+  QCPDataSelection is thus used.
+  
+  Both \ref QCPDataRange and \ref QCPDataSelection offer convenience methods to work with them,
+  e.g. \ref bounded, \ref expanded, \ref intersects, \ref intersection, \ref adjusted, \ref
+  contains. Further, addition and subtraction operators (defined in \ref QCPDataSelection) can be
+  used to join/subtract data ranges and data selections (or mixtures), to retrieve a corresponding
+  \ref QCPDataSelection.
+  
+  %QCustomPlot's \ref dataselection "data selection mechanism" is based on \ref QCPDataSelection and
+  QCPDataRange.

+/*! \class QCPDataSelection
+  \brief Describes a data set by holding multiple QCPDataRange instances
+  
+  QCPDataSelection manages multiple instances of QCPDataRange in order to represent any (possibly
+  disjoint) set of data selection.
+  
+  The data selection can be modified with addition and subtraction operators which take
+  QCPDataSelection and QCPDataRange instances, as well as methods such as \ref addDataRange and
+  \ref clear. Read access is provided by \ref dataRange, \ref dataRanges, \ref dataRangeCount, etc.
+  
+  The method \ref simplify is used to join directly adjacent or even overlapping QCPDataRange
+  instances. QCPDataSelection automatically simplifies when using the addition/subtraction
+  operators. The only case when \ref simplify is left to the user, is when calling \ref
+  addDataRange, with the parameter \a simplify explicitly set to false. This is useful if many data
+  ranges will be added to the selection successively and the overhead for simplifying after each
+  iteration shall be avoided. In this case, you should make sure to call \ref simplify after
+  completing the operation.
+  
+  Use \ref enforceType to bring the data selection into a state complying with the constraints for
+  selections defined in \ref QCP::SelectionType.
+  
+  %QCustomPlot's \ref dataselection "data selection mechanism" is based on QCPDataSelection and
+  QCPDataRange.

+  they will all have the same size, based on the largest required margin in the group.
+  
+  \n
+  \image html QCPMarginGroup.png "Demonstration of QCPMarginGroup"
+  \n
+  
+  In certain situations it is desirable that margins at specific sides are synchronized across
+  layout elements. For example, if one QCPAxisRect is below another one in a grid layout, it will
+  provide a cleaner look to the user if the left and right margins of the two axis rects are of the
+  same size. The left axis of the top axis rect will then be at the same horizontal position as the
+  left axis of the lower axis rect, making them appear aligned. The same applies for the right
+  axes. This is what QCPMarginGroup makes possible.
+  
+  To add/remove a specific side of a layout element to/from a margin group, use the \ref
+  QCPLayoutElement::setMarginGroup method. To completely break apart the margin group, either call
+  \ref clear, or just delete the margin group.
+  
+  \section QCPMarginGroup-example Example
+  
+  First create a margin group:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpmargingroup-creation-1
+  Then set this group on the layout element sides:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpmargingroup-creation-2
+  Here, we've used the first two axis rects of the plot and synchronized their left margins with
+  each other and their right margins with each other.

+/*! \class QCPLayoutElement
+  \brief The abstract base class for all objects that form \ref thelayoutsystem "the layout system".
+  
+  This is an abstract base class. As such, it can't be instantiated directly, rather use one of its subclasses.
+  
+  A Layout element is a rectangular object which can be placed in layouts. It has an outer rect
+  (QCPLayoutElement::outerRect) and an inner rect (\ref QCPLayoutElement::rect). The difference
+  between outer and inner rect is called its margin. The margin can either be set to automatic or
+  manual (\ref setAutoMargins) on a per-side basis. If a side is set to manual, that margin can be
+  set explicitly with \ref setMargins and will stay fixed at that value. If it's set to automatic,
+  the layout element subclass will control the value itself (via \ref calculateAutoMargin).
+  
+  Layout elements can be placed in layouts (base class QCPLayout) like QCPLayoutGrid. The top level
+  layout is reachable via \ref QCustomPlot::plotLayout, and is a \ref QCPLayoutGrid. Since \ref
+  QCPLayout itself derives from \ref QCPLayoutElement, layouts can be nested.
+  
+  Thus in QCustomPlot one can divide layout elements into two categories: The ones that are
+  invisible by themselves, because they don't draw anything. Their only purpose is to manage the
+  position and size of other layout elements. This category of layout elements usually use
+  QCPLayout as base class. Then there is the category of layout elements which actually draw
+  something. For example, QCPAxisRect, QCPLegend and QCPTextElement are of this category. This does
+  not necessarily mean that the latter category can't have child layout elements. QCPLegend for
+  instance, actually derives from QCPLayoutGrid and the individual legend items are child layout
+  elements in the grid layout.

+
+  Elements can be added to cells via \ref addElement. The grid is expanded if the specified row or

+  remove.
+
+  If you use \ref addElement(QCPLayoutElement*) without explicit parameters for \a row and \a
+  column, the grid layout will choose the position according to the current \ref setFillOrder and

+  \brief The base class tick generator used by QCPAxis to create tick positions and tick labels
+  
+  Each QCPAxis has an internal QCPAxisTicker (or a subclass) in order to generate tick positions
+  and tick labels for the current axis range. The ticker of an axis can be set via \ref
+  QCPAxis::setTicker. Since that method takes a <tt>QSharedPointer<QCPAxisTicker></tt>, multiple

+  \section axisticker-subclassing Creating own axis tickers
+  
+  Creating own axis tickers can be achieved very easily by sublassing QCPAxisTicker and
+  reimplementing some or all of the available virtual methods.
+
+  In the simplest case you might wish to just generate different tick steps than the other tickers,
+  so you only reimplement the method \ref getTickStep. If you additionally want control over the
+  string that will be shown as tick label, reimplement \ref getTickLabel.
+  
+  If you wish to have complete control, you can generate the tick vectors and tick label vectors
+  yourself by reimplementing \ref createTickVector and \ref createLabelVector. The default
+  implementations use the previously mentioned virtual methods \ref getTickStep and \ref
+  getTickLabel, but your reimplementations don't necessarily need to do so. For example in the case
+  of unequal tick steps, the method \ref getTickStep loses its usefulness and can be ignored.
+  
+  The sub tick count between major ticks can be controlled with \ref getSubTickCount. Full sub tick
+  placement control is obtained by reimplementing \ref createSubTickVector.
+  
+  See the documentation of all these virtual methods in QCPAxisTicker for detailed information
+  about the parameters and expected return values.

+/*! \class QCPAxisTickerDateTime
+  \brief Specialized axis ticker for calendar dates and times as axis ticks
+  
+  \image html axisticker-datetime.png
+  
+  This QCPAxisTicker subclass generates ticks that correspond to real calendar dates and times. The
+  plot axis coordinate is interpreted as Unix Time, so seconds since Epoch (January 1, 1970, 00:00
+  UTC). This is also used for example by QDateTime in the <tt>toTime_t()/setTime_t()</tt> methods
+  with a precision of one second. Since Qt 4.7, millisecond accuracy can be obtained from QDateTime
+  by using <tt>QDateTime::fromMSecsSinceEpoch()/1000.0</tt>. The static methods \ref dateTimeToKey
+  and \ref keyToDateTime conveniently perform this conversion achieving a precision of one
+  millisecond on all Qt versions.
+  
+  The format of the date/time display in the tick labels is controlled with \ref setDateTimeFormat.
+  If a different time spec (time zone) shall be used, see \ref setDateTimeSpec.
+  
+  This ticker produces unequal tick spacing in order to provide intuitive date and time-of-day
+  ticks. For example, if the axis range spans a few years such that there is one tick per year,
+  ticks will be positioned on 1. January of every year. This is intuitive but, due to leap years,
+  will result in slightly unequal tick intervals (visually unnoticeable). The same can be seen in
+  the image above: even though the number of days varies month by month, this ticker generates
+  ticks on the same day of each month.
+  
+  If you would like to change the date/time that is used as a (mathematical) starting date for the
+  ticks, use the \ref setTickOrigin(const QDateTime &origin) method overload, which takes a
+  QDateTime. If you pass 15. July, 9:45 to this method, the yearly ticks will end up on 15. July at
+  9:45 of every year.
+  
+  The ticker can be created and assigned to an axis like this:
+  \snippet documentation/doc-image-generator/mainwindow.cpp axistickerdatetime-creation
+  
+  \note If you rather wish to display relative times in terms of days, hours, minutes, seconds and
+  milliseconds, and are not interested in the intricacies of real calendar dates with months and
+  (leap) years, have a look at QCPAxisTickerTime instead.

+/*! \class QCPAxisTickerTime
+  \brief Specialized axis ticker for time spans in units of milliseconds to days
+  
+  \image html axisticker-time.png
+  
+  This QCPAxisTicker subclass generates ticks that corresponds to time intervals.
+  
+  The format of the time display in the tick labels is controlled with \ref setTimeFormat and \ref
+  setFieldWidth. The time coordinate is in the unit of seconds with respect to the time coordinate
+  zero. Unlike with QCPAxisTickerDateTime, the ticks don't correspond to a specific calendar date
+  and time.
+  
+  The time can be displayed in milliseconds, seconds, minutes, hours and days. Depending on the
+  largest available unit in the format specified with \ref setTimeFormat, any time spans above will
+  be carried in that largest unit. So for example if the format string is "%m:%s" and a tick at
+  coordinate value 7815 (being 2 hours, 10 minutes and 15 seconds) is created, the resulting tick
+  label will show "130:15" (130 minutes, 15 seconds). If the format string is "%h:%m:%s", the hour
+  unit will be used and the label will thus be "02:10:15". Negative times with respect to the axis
+  zero will carry a leading minus sign.
+  
+  The ticker can be created and assigned to an axis like this:
+  \snippet documentation/doc-image-generator/mainwindow.cpp axistickertime-creation
+  
+  Here is an example of a time axis providing time information in days, hours and minutes. Due to
+  the axis range spanning a few days and the wanted tick count (\ref setTickCount), the ticker
+  decided to use tick steps of 12 hours:
+  
+  \image html axisticker-time2.png
+  
+  The format string for this example is
+  \snippet documentation/doc-image-generator/mainwindow.cpp axistickertime-creation-2
+  
+  \note If you rather wish to display calendar dates and times, have a look at QCPAxisTickerDateTime
+  instead.

+  QCPAxis::grid. Normally, you don't need to create an instance of QCPGrid yourself.
+  
+  The axis and grid drawing was split into two classes to allow them to be placed on different
+  layers (both QCPAxis and QCPGrid inherit from QCPLayerable). Thus it is possible to have the grid
+  in the background and the axes in the foreground, and any plottables/items in between. This
+  described situation is the default setup, see the QCPLayer documentation.

+  
+  \a formatCode is a string of one, two or three characters. The first character is identical to
+  the normal format code used by Qt. In short, this means: 'e'/'E' scientific format, 'f' fixed
+  format, 'g'/'G' scientific or fixed, whichever is shorter.
+  
+  The second and third characters are optional and specific to QCustomPlot:\n
+  If the first char was 'e' or 'g', numbers are/might be displayed in the scientific format, e.g.
+  "5.5e9", which is ugly in a plot. So when the second char of \a formatCode is set to 'b' (for
+  "beautiful"), those exponential numbers are formatted in a more natural way, i.e. "5.5
+  [multiplication sign] 10 [superscript] 9". By default, the multiplication sign is a centered dot.
+  If instead a cross should be shown (as is usual in the USA), the third char of \a formatCode can
+  be set to 'c'. The inserted multiplication signs are the UTF-8 characters 215 (0xD7) for the
+  cross and 183 (0xB7) for the dot.
+  
+  Examples for \a formatCode:
+  \li \c g normal format code behaviour. If number is small, fixed format is used, if number is large,
+  normal scientific format is used
+  \li \c gb If number is small, fixed format is used, if number is large, scientific format is used with
+  beautifully typeset decimal powers and a dot as multiplication sign
+  \li \c ebc All numbers are in scientific format with beautifully typeset decimal power and a cross as
+  multiplication sign
+  \li \c fb illegal format code, since fixed format doesn't support (or need) beautifully typeset decimal
+  powers. Format code will be reduced to 'f'.
+  \li \c hello illegal format code, since first char is not 'e', 'E', 'f', 'g' or 'G'. Current format

+/*! \class QCPScatterStyle
+  \brief Represents the visual appearance of scatter points
+  
+  This class holds information about shape, color and size of scatter points. In plottables like
+  QCPGraph it is used to store how scatter points shall be drawn. For example, \ref
+  QCPGraph::setScatterStyle takes a QCPScatterStyle instance.
+  
+  A scatter style consists of a shape (\ref setShape), a line color (\ref setPen) and possibly a
+  fill (\ref setBrush), if the shape provides a fillable area. Further, the size of the shape can
+  be controlled with \ref setSize.
+
+  \section QCPScatterStyle-defining Specifying a scatter style
+  
+  You can set all these configurations either by calling the respective functions on an instance:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpscatterstyle-creation-1
+  
+  Or you can use one of the various constructors that take different parameter combinations, making
+  it easy to specify a scatter style in a single call, like so:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpscatterstyle-creation-2
+  
+  \section QCPScatterStyle-undefinedpen Leaving the color/pen up to the plottable
+  
+  There are two constructors which leave the pen undefined: \ref QCPScatterStyle() and \ref
+  QCPScatterStyle(ScatterShape shape, double size). If those constructors are used, a call to \ref
+  isPenDefined will return false. It leads to scatter points that inherit the pen from the
+  plottable that uses the scatter style. Thus, if such a scatter style is passed to QCPGraph, the line
+  color of the graph (\ref QCPGraph::setPen) will be used by the scatter points. This makes
+  it very convenient to set up typical scatter settings:
+  
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpscatterstyle-shortcreation
+
+  Notice that it wasn't even necessary to explicitly call a QCPScatterStyle constructor. This works
+  because QCPScatterStyle provides a constructor that can transform a \ref ScatterShape directly
+  into a QCPScatterStyle instance (that's the \ref QCPScatterStyle(ScatterShape shape, double size)
+  constructor with a default for \a size). In those cases, C++ allows directly supplying a \ref
+  ScatterShape, where actually a QCPScatterStyle is expected.
+  
+  \section QCPScatterStyle-custompath-and-pixmap Custom shapes and pixmaps
+  
+  QCPScatterStyle supports drawing custom shapes and arbitrary pixmaps as scatter points.
+
+  For custom shapes, you can provide a QPainterPath with the desired shape to the \ref
+  setCustomPath function or call the constructor that takes a painter path. The scatter shape will
+  automatically be set to \ref ssCustom.
+  
+  For pixmaps, you call \ref setPixmap with the desired QPixmap. Alternatively you can use the
+  constructor that takes a QPixmap. The scatter shape will automatically be set to \ref ssPixmap.
+  Note that \ref setSize does not influence the appearance of the pixmap.

+/*! \class QCPSelectionDecorator
+  \brief Controls how a plottable's data selection is drawn
+  
+  Each \ref QCPAbstractPlottable instance has one \ref QCPSelectionDecorator (accessible via \ref
+  QCPAbstractPlottable::selectionDecorator) and uses it when drawing selected segments of its data.
+  
+  The selection decorator controls both pen (\ref setPen) and brush (\ref setBrush), as well as the
+  scatter style (\ref setScatterStyle) if the plottable draws scatters. Since a \ref
+  QCPScatterStyle is itself composed of different properties such as color shape and size, the
+  decorator allows specifying exactly which of those properties shall be used for the selected data
+  point, via \ref setUsedScatterProperties.
+  
+  A \ref QCPSelectionDecorator subclass instance can be passed to a plottable via \ref
+  QCPAbstractPlottable::setSelectionDecorator, allowing greater customizability of the appearance
+  of selected segments.
+  
+  Use \ref copyFrom to easily transfer the settings of one decorator to another one. This is
+  especially useful since plottables take ownership of the passed selection decorator, and thus the
+  same decorator instance can not be passed to multiple plottables.
+  
+  Selection decorators can also themselves perform drawing operations by reimplementing \ref
+  drawDecoration, which is called by the plottable's draw method. The base class \ref
+  QCPSelectionDecorator does not make use of this however. For example, \ref
+  QCPSelectionDecoratorBracket draws brackets around selected data segments.

+
+/*! \class QCPAbstractPlottable
+  \brief The abstract base class for all data representing objects in a plot.
+
+  It defines a very basic interface like name, pen, brush, visibility etc. Since this class is
+  abstract, it can't be instantiated. Use one of the subclasses or create a subclass yourself to
+  create new ways of displaying data (see "Creating own plottables" below). Plottables that display
+  one-dimensional data (i.e. data points have a single key dimension and one or multiple values at
+  each key) are based off of the template subclass \ref QCPAbstractPlottable1D, see details
+  there.
+  
+  All further specifics are in the subclasses, for example:
+  \li A normal graph with possibly a line and/or scatter points \ref QCPGraph
+  (typically created with \ref QCustomPlot::addGraph)
+  \li A parametric curve: \ref QCPCurve
+  \li A bar chart: \ref QCPBars
+  \li A statistical box plot: \ref QCPStatisticalBox
+  \li A color encoded two-dimensional map: \ref QCPColorMap
+  \li An OHLC/Candlestick chart: \ref QCPFinancial
+  
+  \section plottables-subclassing Creating own plottables
+  
+  Subclassing directly from QCPAbstractPlottable is only recommended if you wish to display
+  two-dimensional data like \ref QCPColorMap, i.e. two logical key dimensions and one (or more)
+  data dimensions. If you want to display data with only one logical key dimension, you should
+  rather derive from \ref QCPAbstractPlottable1D.
+  
+  If subclassing QCPAbstractPlottable directly, these are the pure virtual functions you must
+  implement:
+  \li \ref selectTest
+  \li \ref draw
+  \li \ref drawLegendIcon
+  \li \ref getKeyRange
+  \li \ref getValueRange
+  
+  See the documentation of those functions for what they need to do.
+  
+  For drawing your plot, you can use the \ref coordsToPixels functions to translate a point in plot
+  coordinates to pixel coordinates. This function is quite convenient, because it takes the
+  orientation of the key and value axes into account for you (x and y are swapped when the key axis
+  is vertical and the value axis horizontal). If you are worried about performance (i.e. you need
+  to translate many points in a loop like QCPGraph), you can directly use \ref
+  QCPAxis::coordToPixel. However, you must then take care about the orientation of the axis
+  yourself.
+  
+  Here are some important members you inherit from QCPAbstractPlottable:
+  <table>
+  <tr>
+    <td>QCustomPlot *\b mParentPlot</td>
+    <td>A pointer to the parent QCustomPlot instance. The parent plot is inferred from the axes that are passed in the constructor.</td>
+  </tr><tr>
+    <td>QString \b mName</td>
+    <td>The name of the plottable.</td>
+  </tr><tr>
+    <td>QPen \b mPen</td>
+    <td>The generic pen of the plottable. You should use this pen for the most prominent data representing lines in the plottable
+        (e.g QCPGraph uses this pen for its graph lines and scatters)</td>
+  </tr><tr>
+    <td>QBrush \b mBrush</td>
+    <td>The generic brush of the plottable. You should use this brush for the most prominent fillable structures in the plottable
+        (e.g. QCPGraph uses this brush to control filling under the graph)</td>
+  </tr><tr>
+    <td>QPointer<\ref QCPAxis> \b mKeyAxis, \b mValueAxis</td>
+    <td>The key and value axes this plottable is attached to. Call their QCPAxis::coordToPixel functions to translate coordinates
+        to pixels in either the key or value dimension. Make sure to check whether the pointer is null before using it. If one of
+        the axes is null, don't draw the plottable.</td>
+  </tr><tr>
+    <td>\ref QCPSelectionDecorator \b mSelectionDecorator</td>
+    <td>The currently set selection decorator which specifies how selected data of the plottable shall be drawn and decorated.
+        When drawing your data, you must consult this decorator for the appropriate pen/brush before drawing unselected/selected data segments.
+        Finally, you should call its \ref QCPSelectionDecorator::drawDecoration method at the end of your \ref draw implementation.</td>
+  </tr><tr>
+    <td>\ref QCP::SelectionType \b mSelectable</td>
+    <td>In which composition, if at all, this plottable's data may be selected. Enforcing this setting on the data selection is done
+        by QCPAbstractPlottable automatically.</td>
+  </tr><tr>
+    <td>\ref QCPDataSelection \b mSelection</td>
+    <td>Holds the current selection state of the plottable's data, i.e. the selected data ranges (\ref QCPDataRange).</td>

+/*! \class QCPItemAnchor
+  \brief An anchor of an item to which positions can be attached to.
+  
+  An item (QCPAbstractItem) may have one or more anchors. Unlike QCPItemPosition, an anchor doesn't
+  control anything on its item, but provides a way to tie other items via their positions to the
+  anchor.
+
+  For example, a QCPItemRect is defined by its positions \a topLeft and \a bottomRight.
+  Additionally it has various anchors like \a top, \a topRight or \a bottomLeft etc. So you can
+  attach the \a start (which is a QCPItemPosition) of a QCPItemLine to one of the anchors by
+  calling QCPItemPosition::setParentAnchor on \a start, passing the wanted anchor of the
+  QCPItemRect. This way the start of the line will now always follow the respective anchor location
+  on the rect item.
+  
+  Note that QCPItemPosition derives from QCPItemAnchor, so every position can also serve as an
+  anchor to other positions.
+  
+  To learn how to provide anchors in your own item subclasses, see the subclassing section of the
+  QCPAbstractItem documentation.

+/*! \class QCPItemPosition
+  \brief Manages the position of an item.
+  
+  Every item has at least one public QCPItemPosition member pointer which provides ways to position the
+  item on the QCustomPlot surface. Some items have multiple positions, for example QCPItemRect has two:
+  \a topLeft and \a bottomRight.
+
+  QCPItemPosition has a type (\ref PositionType) that can be set with \ref setType. This type
+  defines how coordinates passed to \ref setCoords are to be interpreted, e.g. as absolute pixel
+  coordinates, as plot coordinates of certain axes, etc. For more advanced plots it is also
+  possible to assign different types per X/Y coordinate of the position (see \ref setTypeX, \ref
+  setTypeY). This way an item could be positioned at a fixed pixel distance from the top in the Y
+  direction, while following a plot coordinate in the X direction.
+
+  A QCPItemPosition may have a parent QCPItemAnchor, see \ref setParentAnchor. This way you can tie
+  multiple items together. If the QCPItemPosition has a parent, its coordinates (\ref setCoords)
+  are considered to be absolute pixels in the reference frame of the parent anchor, where (0, 0)
+  means directly ontop of the parent anchor. For example, You could attach the \a start position of
+  a QCPItemLine to the \a bottom anchor of a QCPItemText to make the starting point of the line
+  always be centered under the text label, no matter where the text is moved to. For more advanced
+  plots, it is possible to assign different parent anchors per X/Y coordinate of the position, see
+  \ref setParentAnchorX, \ref setParentAnchorY. This way an item could follow another item in the X
+  direction but stay at a fixed position in the Y direction. Or even follow item A in X, and item B
+  in Y.
+
+  Note that every QCPItemPosition inherits from QCPItemAnchor and thus can itself be used as parent
+  anchor for other positions.
+
+  To set the apparent pixel position on the QCustomPlot surface directly, use \ref setPixelPosition. This
+  works no matter what type this QCPItemPosition is or what parent-child situation it is in, as \ref
+  setPixelPosition transforms the coordinates appropriately, to make the position appear at the specified
+  pixel values.

+
+  \li The position is regarded as a point in plot coordinates. This corresponds to \ref ptPlotCoords
+  and requires two axes that define the plot coordinate system. They can be specified with \ref setAxes.

+  
+  Note that the position type \ref ptPlotCoords is only available (and sensible) when the position
+  has no parent anchor (\ref setParentAnchor).

+/*! \class QCPAbstractItem
+  \brief The abstract base class for all items in a plot.
+  
+  In QCustomPlot, items are supplemental graphical elements that are neither plottables
+  (QCPAbstractPlottable) nor axes (QCPAxis). While plottables are always tied to two axes and thus
+  plot coordinates, items can also be placed in absolute coordinates independent of any axes. Each
+  specific item has at least one QCPItemPosition member which controls the positioning. Some items
+  are defined by more than one coordinate and thus have two or more QCPItemPosition members (For
+  example, QCPItemRect has \a topLeft and \a bottomRight).
+  
+  This abstract base class defines a very basic interface like visibility and clipping. Since this
+  class is abstract, it can't be instantiated. Use one of the subclasses or create a subclass
+  yourself to create new items.
+  
+  The built-in items are:
+  <table>
+  <tr><td>QCPItemLine</td><td>A line defined by a start and an end point. May have different ending styles on each side (e.g. arrows).</td></tr>
+  <tr><td>QCPItemStraightLine</td><td>A straight line defined by a start and a direction point. Unlike QCPItemLine, the straight line is infinitely long and has no endings.</td></tr>
+  <tr><td>QCPItemCurve</td><td>A curve defined by start, end and two intermediate control points. May have different ending styles on each side (e.g. arrows).</td></tr>
+  <tr><td>QCPItemRect</td><td>A rectangle</td></tr>
+  <tr><td>QCPItemEllipse</td><td>An ellipse</td></tr>
+  <tr><td>QCPItemPixmap</td><td>An arbitrary pixmap</td></tr>
+  <tr><td>QCPItemText</td><td>A text label</td></tr>
+  <tr><td>QCPItemBracket</td><td>A bracket which may be used to reference/highlight certain parts in the plot.</td></tr>
+  <tr><td>QCPItemTracer</td><td>An item that can be attached to a QCPGraph and sticks to its data points, given a key coordinate.</td></tr>
+  </table>
+  
+  \section items-clipping Clipping
+
+  Items are by default clipped to the main axis rect (they are only visible inside the axis rect).
+  To make an item visible outside that axis rect, disable clipping via \ref setClipToAxisRect
+  "setClipToAxisRect(false)".
+
+  On the other hand if you want the item to be clipped to a different axis rect, specify it via
+  \ref setClipAxisRect. This clipAxisRect property of an item is only used for clipping behaviour, and
+  in principle is independent of the coordinate axes the item might be tied to via its position
+  members (\ref QCPItemPosition::setAxes). However, it is common that the axis rect for clipping
+  also contains the axes used for the item positions.
+  
+  \section items-using Using items
+  
+  First you instantiate the item you want to use and add it to the plot:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-1
+  by default, the positions of the item are bound to the x- and y-Axis of the plot. So we can just
+  set the plot coordinates where the line should start/end:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-2
+  If we don't want the line to be positioned in plot coordinates but a different coordinate system,
+  e.g. absolute pixel positions on the QCustomPlot surface, we need to change the position type like this:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-3
+  Then we can set the coordinates, this time in pixels:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-4
+  and make the line visible on the entire QCustomPlot, by disabling clipping to the axis rect:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-5
+  
+  For more advanced plots, it is even possible to set different types and parent anchors per X/Y
+  coordinate of an item position, using for example \ref QCPItemPosition::setTypeX or \ref
+  QCPItemPosition::setParentAnchorX. For details, see the documentation of \ref QCPItemPosition.
+  
+  \section items-subclassing Creating own items
+  
+  To create an own item, you implement a subclass of QCPAbstractItem. These are the pure
+  virtual functions, you must implement:
+  \li \ref selectTest
+  \li \ref draw
+  
+  See the documentation of those functions for what they need to do.
+  
+  \subsection items-positioning Allowing the item to be positioned
+  
+  As mentioned, item positions are represented by QCPItemPosition members. Let's assume the new item shall
+  have only one point as its position (as opposed to two like a rect or multiple like a polygon). You then add
+  a public member of type QCPItemPosition like so:
+  
+  \code QCPItemPosition * const myPosition;\endcode
+  
+  the const makes sure the pointer itself can't be modified from the user of your new item (the QCPItemPosition
+  instance it points to, can be modified, of course).
+  The initialization of this pointer is made easy with the \ref createPosition function. Just assign
+  the return value of this function to each QCPItemPosition in the constructor of your item. \ref createPosition
+  takes a string which is the name of the position, typically this is identical to the variable name.
+  For example, the constructor of QCPItemExample could look like this:
+  
+  \code
+  QCPItemExample::QCPItemExample(QCustomPlot *parentPlot) :
+    QCPAbstractItem(parentPlot),
+    myPosition(createPosition("myPosition"))
+  {
+    // other constructor code
+  }
+  \endcode
+  
+  \subsection items-drawing The draw function
+  
+  To give your item a visual representation, reimplement the \ref draw function and use the passed
+  QCPPainter to draw the item. You can retrieve the item position in pixel coordinates from the
+  position member(s) via \ref QCPItemPosition::pixelPosition.
+
+  To optimize performance you should calculate a bounding rect first (don't forget to take the pen
+  width into account), check whether it intersects the \ref clipRect, and only draw the item at all
+  if this is the case.
+  
+  \subsection items-selection The selectTest function
+  
+  Your implementation of the \ref selectTest function may use the helpers \ref
+  QCPVector2D::distanceSquaredToLine and \ref rectDistance. With these, the implementation of the
+  selection test becomes significantly simpler for most items. See the documentation of \ref
+  selectTest for what the function parameters mean and what the function should return.
+  
+  \subsection anchors Providing anchors
+  
+  Providing anchors (QCPItemAnchor) starts off like adding a position. First you create a public
+  member, e.g.
+  
+  \code QCPItemAnchor * const bottom;\endcode
+
+  and create it in the constructor with the \ref createAnchor function, assigning it a name and an
+  anchor id (an integer enumerating all anchors on the item, you may create an own enum for this).
+  Since anchors can be placed anywhere, relative to the item's position(s), your item needs to
+  provide the position of every anchor with the reimplementation of the \ref anchorPixelPosition(int
+  anchorId) function.
+  
+  In essence the QCPItemAnchor is merely an intermediary that itself asks your item for the pixel
+  position when anything attached to the anchor needs to know the coordinates.

+  For details how to control which axes the user may drag/zoom and in what orientations, see \ref
+  QCPAxisRect::setRangeDrag, \ref QCPAxisRect::setRangeZoom, \ref QCPAxisRect::setRangeDragAxes,
+  \ref QCPAxisRect::setRangeZoomAxes.
+  
+  <b>Plottable data selection</b> is controlled by \ref QCP::iSelectPlottables. If \ref
+  QCP::iSelectPlottables is set, the user may select plottables (graphs, curves, bars,...) and
+  their data by clicking on them or in their vicinity (\ref setSelectionTolerance). Whether the
+  user can actually select a plottable and its data can further be restricted with the \ref
+  QCPAbstractPlottable::setSelectable method on the specific plottable. For details, see the
+  special page about the \ref dataselection "data selection mechanism". To retrieve a list of all
+  currently selected plottables, call \ref selectedPlottables. If you're only interested in
+  QCPGraphs, you may use the convenience function \ref selectedGraphs.
+  
+  <b>Item selection</b> is controlled by \ref QCP::iSelectItems. If \ref QCP::iSelectItems is set, the user
+  may select items (QCPItemLine, QCPItemText,...) by clicking on them or in their vicinity. To find
+  out whether a specific item is selected, call QCPAbstractItem::selected(). To retrieve a list of
+  all currently selected items, call \ref selectedItems.
+  
+  <b>Axis selection</b> is controlled with \ref QCP::iSelectAxes. If \ref QCP::iSelectAxes is set, the user
+  may select parts of the axes by clicking on them. What parts exactly (e.g. Axis base line, tick
+  labels, axis label) are selectable can be controlled via \ref QCPAxis::setSelectableParts for
+  each axis. To retrieve a list of all axes that currently contain selected parts, call \ref
+  selectedAxes. Which parts of an axis are selected, can be retrieved with QCPAxis::selectedParts().
+  
+  <b>Legend selection</b> is controlled with \ref QCP::iSelectLegend. If this is set, the user may
+  select the legend itself or individual items by clicking on them. What parts exactly are
+  selectable can be controlled via \ref QCPLegend::setSelectableParts. To find out whether the
+  legend or any of its child items are selected, check the value of QCPLegend::selectedParts. To
+  find out which child items are selected, call \ref QCPLegend::selectedItems.
+  
+  <b>All other selectable elements</b> The selection of all other selectable objects (e.g.
+  QCPTextElement, or your own layerable subclasses) is controlled with \ref QCP::iSelectOther. If set, the
+  user may select those objects by clicking on them. To find out which are currently selected, you
+  need to check their selected state explicitly.
+  
+  If the selection state has changed by user interaction, the \ref selectionChangedByUser signal is
+  emitted. Each selectable object additionally emits an individual selectionChanged signal whenever
+  their selection state has changed, i.e. not only by user interaction.

+  setMultiSelectModifier), set the flag \ref QCP::iMultiSelect.

+  \warning This is still an experimental feature and its performance depends on the system that it

+  might cause context conflicts on some systems.
+  
+  This method allows to enable OpenGL plot rendering, for increased plotting performance of
+  graphically demanding plots (thick lines, translucent fills, etc.).
+
+  If \a enabled is set to true, QCustomPlot will try to initialize OpenGL and, if successful,
+  continue plotting with hardware acceleration. The parameter \a multisampling controls how many
+  samples will be used per pixel, it essentially controls the antialiasing quality. If \a
+  multisampling is set too high for the current graphics hardware, the maximum allowed value will
+  be used.
+
+  You can test whether switching to OpenGL rendering was successful by checking whether the
+  according getter \a QCustomPlot::openGl() returns true. If the OpenGL initialization fails,
+  rendering continues with the regular software rasterizer, and an according qDebug output is
+  generated.
+
+  If switching to OpenGL was successful, this method disables label caching (\ref setPlottingHint
+  "setPlottingHint(QCP::phCacheLabels, false)") and turns on QCustomPlot's antialiasing override
+  for all elements (\ref setAntialiasedElements "setAntialiasedElements(QCP::aeAll)"), leading to a
+  higher quality output. The antialiasing override allows for pixel-grid aligned drawing in the
+  OpenGL paint device. As stated before, in OpenGL rendering the actual antialiasing of the plot is
+  controlled with \a multisampling. If \a enabled is set to false, the antialiasing/label caching
+  settings are restored to what they were before OpenGL was enabled, if they weren't altered in the
+  meantime.
+
+  \note OpenGL support is only enabled if QCustomPlot is compiled with the macro \c QCUSTOMPLOT_USE_OPENGL
+  defined. This define must be set before including the QCustomPlot header both during compilation
+  of the QCustomPlot library as well as when compiling your application. It is best to just include
+  the line <tt>DEFINES += QCUSTOMPLOT_USE_OPENGL</tt> in the respective qmake project files.
+  \note If you are using a Qt version before 5.0, you must also add the module "opengl" to your \c
+  QT variable in the qmake project files. For Qt versions 5.0 and higher, QCustomPlot switches to a
+  newer OpenGL interface which is already in the "gui" module.

+

+
+  Before the replot happens, the signal \ref beforeReplot is emitted. After the replot, \ref
+  afterReplot is emitted. It is safe to mutually connect the replot slot with any of those two

+  recursion.

+/*! \class QCPColorGradient
+  \brief Defines a color gradient for use with e.g. \ref QCPColorMap
+  
+  This class describes a color gradient which can be used to encode data with color. For example,
+  QCPColorMap and QCPColorScale have \ref QCPColorMap::setGradient "setGradient" methods which
+  take an instance of this class. Colors are set with \ref setColorStopAt(double position, const QColor &color)
+  with a \a position from 0 to 1. In between these defined color positions, the
+  color will be interpolated linearly either in RGB or HSV space, see \ref setColorInterpolation.
+
+  Alternatively, load one of the preset color gradients shown in the image below, with \ref
+  loadPreset, or by directly specifying the preset in the constructor.
+  
+  Apart from red, green and blue components, the gradient also interpolates the alpha values of the
+  configured color stops. This allows to display some portions of the data range as transparent in
+  the plot.
+  
+  \image html QCPColorGradient.png
+  
+  The \ref QCPColorGradient(GradientPreset preset) constructor allows directly converting a \ref
+  GradientPreset to a QCPColorGradient. This means that you can directly pass \ref GradientPreset
+  to all the \a setGradient methods, e.g.:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorgradient-setgradient
+  
+  The total number of levels used in the gradient can be set with \ref setLevelCount. Whether the
+  color gradient shall be applied periodically (wrapping around) to data values that lie outside
+  the data range specified on the plottable instance can be controlled with \ref setPeriodic.

+/*! \class QCPAxisRect
+  \brief Holds multiple axes and arranges them in a rectangular shape.
+  
+  This class represents an axis rect, a rectangular area that is bounded on all sides with an
+  arbitrary number of axes.
+  
+  Initially QCustomPlot has one axis rect, accessible via QCustomPlot::axisRect(). However, the
+  layout system allows to have multiple axis rects, e.g. arranged in a grid layout
+  (QCustomPlot::plotLayout).
+  
+  By default, QCPAxisRect comes with four axes, at bottom, top, left and right. They can be
+  accessed via \ref axis by providing the respective axis type (\ref QCPAxis::AxisType) and index.
+  If you need all axes in the axis rect, use \ref axes. The top and right axes are set to be
+  invisible initially (QCPAxis::setVisible). To add more axes to a side, use \ref addAxis or \ref
+  addAxes. To remove an axis, use \ref removeAxis.
+  
+  The axis rect layerable itself only draws a background pixmap or color, if specified (\ref
+  setBackground). It is placed on the "background" layer initially (see \ref QCPLayer for an
+  explanation of the QCustomPlot layer system). The axes that are held by the axis rect can be
+  placed on other layers, independently of the axis rect.
+  
+  Every axis rect has a child layout of type \ref QCPLayoutInset. It is accessible via \ref
+  insetLayout and can be used to have other layout elements (or even other layouts with multiple
+  elements) hovering inside the axis rect.
+  
+  If an axis rect is clicked and dragged, it processes this by moving certain axis ranges. The
+  behaviour can be controlled with \ref setRangeDrag and \ref setRangeDragAxes. If the mouse wheel

+  For example, the QCPGraph draws a centered horizontal line and/or a single scatter point in the

+/*! \class QCPLegend
+  \brief Manages a legend inside a QCustomPlot.
+
+  A legend is a small box somewhere in the plot which lists plottables with their name and icon.
+
+  A legend is populated with legend items by calling \ref QCPAbstractPlottable::addToLegend on the
+  plottable, for which a legend item shall be created. In the case of the main legend (\ref
+  QCustomPlot::legend), simply adding plottables to the plot while \ref
+  QCustomPlot::setAutoAddPlottableToLegend is set to true (the default) creates corresponding
+  legend items. The legend item associated with a certain plottable can be removed with \ref
+  QCPAbstractPlottable::removeFromLegend. However, QCPLegend also offers an interface to add and
+  manipulate legend items directly: \ref item, \ref itemWithPlottable, \ref itemCount, \ref
+  addItem, \ref removeItem, etc.
+
+  Since \ref QCPLegend derives from \ref QCPLayoutGrid, it can be placed in any position a \ref
+  QCPLayoutElement may be positioned. The legend items are themselves \ref QCPLayoutElement
+  "QCPLayoutElements" which are placed in the grid layout of the legend. \ref QCPLegend only adds
+  an interface specialized for handling child elements of type \ref QCPAbstractLegendItem, as
+  mentioned above. In principle, any other layout elements may also be added to a legend via the
+  normal \ref QCPLayoutGrid interface. See the special page about \link thelayoutsystem The Layout
+  System\endlink for examples on how to add other elements to the legend and move it outside the axis
+  rect.
+
+  Use the methods \ref setFillOrder and \ref setWrap inherited from \ref QCPLayoutGrid to control
+  in which order (column first or row first) the legend is filled up when calling \ref addItem, and
+  at which column or row wrapping occurs.
+
+  By default, every QCustomPlot has one legend (\ref QCustomPlot::legend) which is placed in the
+  inset layout of the main axis rect (\ref QCPAxisRect::insetLayout). To move the legend to another
+  position inside the axis rect, use the methods of the \ref QCPLayoutInset. To move the legend
+  outside of the axis rect, place it anywhere else with the \ref QCPLayout/\ref QCPLayoutElement
+  interface.

+/*! \class QCPColorScale
+  \brief A color scale for use with color coding data such as QCPColorMap
+  
+  This layout element can be placed on the plot to correlate a color gradient with data values. It
+  is usually used in combination with one or multiple \ref QCPColorMap "QCPColorMaps".
+
+  \image html QCPColorScale.png
+  
+  The color scale can be either horizontal or vertical, as shown in the image above. The
+  orientation and the side where the numbers appear is controlled with \ref setType.
+  
+  Use \ref QCPColorMap::setColorScale to connect a color map with a color scale. Once they are
+  connected, they share their gradient, data range and data scale type (\ref setGradient, \ref
+  setDataRange, \ref setDataScaleType). Multiple color maps may be associated with a single color
+  scale, to make them all synchronize these properties.
+  
+  To have finer control over the number display and axis behaviour, you can directly access the
+  \ref axis. See the documentation of QCPAxis for details about configuring axes. For example, if
+  you want to change the number of automatically generated ticks, call
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorscale-tickcount
+  
+  Placing a color scale next to the main axis rect works like with any other layout element:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorscale-creation
+  In this case we have placed it to the right of the default axis rect, so it wasn't necessary to
+  call \ref setType, since \ref QCPAxis::atRight is already the default. The text next to the color
+  scale can be set with \ref setLabel.
+  
+  For optimum appearance (like in the image above), it may be desirable to line up the axis rect and
+  the borders of the color scale. Use a \ref QCPMarginGroup to achieve this:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorscale-margingroup
+  
+  Color scales are initialized with a non-zero minimum top and bottom margin (\ref
+  setMinimumMargins), because vertical color scales are most common and the minimum top/bottom
+  margin makes sure it keeps some distance to the top/bottom widget border. So if you change to a
+  horizontal color scale by setting \ref setType to \ref QCPAxis::atBottom or \ref QCPAxis::atTop, you
+  might want to also change the minimum margins accordingly, e.g. <tt>setMinimumMargins(QMargins(6, 0, 6, 0))</tt>.

+  setDataScaleType (\ref QCPAxis::setScaleType), and the method \ref setLabel (\ref
+  QCPAxis::setLabel). As they each are connected, it does not matter whether you use the method on
+  the QCPColorScale or on its QCPAxis.
+  
+  If the type of the color scale is changed with \ref setType, the axis returned by this method
+  will change, too, to either the left, right, bottom or top axis, depending on which type was set.

+  \brief A plottable representing a graph in a plot.
+
+  \image html QCPGraph.png
+  
+  Usually you create new graphs by calling QCustomPlot::addGraph. The resulting instance can be
+  accessed via QCustomPlot::graph.
+
+  To plot data, assign it with the \ref setData or \ref addData functions. Alternatively, you can
+  also access and modify the data via the \ref data method, which returns a pointer to the internal
+  \ref QCPGraphDataContainer.
+  
+  Graphs are used to display single-valued data. Single-valued means that there should only be one
+  data point per unique key coordinate. In other words, the graph can't have \a loops. If you do
+  want to plot non-single-valued curves, rather use the QCPCurve plottable.
+  
+  Gaps in the graph line can be created by adding data points with NaN as value
+  (<tt>qQNaN()</tt> or <tt>std::numeric_limits<double>::quiet_NaN()</tt>) in between the two data points that shall be
+  separated.
+  
+  \section qcpgraph-appearance Changing the appearance
+  
+  The appearance of the graph is mainly determined by the line style, scatter style, brush and pen
+  of the graph (\ref setLineStyle, \ref setScatterStyle, \ref setBrush, \ref setPen).
+  
+  \subsection filling Filling under or between graphs
+  
+  QCPGraph knows two types of fills: Normal graph fills towards the zero-value-line parallel to
+  the key axis of the graph, and fills between two graphs, called channel fills. To enable a fill,
+  just set a brush with \ref setBrush which is neither Qt::NoBrush nor fully transparent.
+  
+  By default, a normal fill towards the zero-value-line will be drawn. To set up a channel fill
+  between this graph and another one, call \ref setChannelFillGraph with the other graph as
+  parameter.

+  of points (e.g. above 10,000), without notably changing the appearance of the graph.
+  
+  By default, adaptive sampling is enabled. Even if enabled, QCustomPlot decides whether adaptive

+  \image html adaptive-sampling-line.png "A line plot of 500,000 points without and with adaptive sampling"

+  As can be seen, line plots experience no visual degradation from adaptive sampling. Outliers are

+  dramatically though. This allows QCustomPlot to display large amounts of data in realtime.
+  
+  \image html adaptive-sampling-scatter.png "A scatter plot of 100,000 points without and with adaptive sampling"
+  
+  Care must be taken when using high-density scatter plots in combination with adaptive sampling.
+  The adaptive sampling algorithm treats scatter plots more carefully than line plots which still
+  gives a significant reduction of replot times, but not quite as much as for line plots. This is
+  because scatter plots inherently need more data points to be preserved in order to still resemble
+  the original, non-adaptive-sampling plot. As shown above, the results still aren't quite
+  identical, as banding occurs for the outer data points. This is in fact intentional, such that
+  the boundaries of the data cloud stay visible to the viewer. How strong the banding appears,
+  depends on the point density, i.e. the number of points in the plot.
+  
+  For some situations with scatter plots it might thus be desirable to manually turn adaptive
+  sampling off. For example, when saving the plot to disk. This can be achieved by setting \a
+  enabled to false before issuing a command like \ref QCustomPlot::savePng, and setting \a enabled

+  \brief A plottable representing a parametric curve in a plot.
+  
+  \image html QCPCurve.png
+  
+  Unlike QCPGraph, plottables of this type may have multiple points with the same key coordinate,
+  so their visual representation can have \a loops. This is realized by introducing a third
+  coordinate \a t, which defines the order of the points described by the other two coordinates \a
+  x and \a y.
+
+  To plot data, assign it with the \ref setData or \ref addData functions. Alternatively, you can
+  also access and modify the curve's data via the \ref data method, which returns a pointer to the
+  internal \ref QCPCurveDataContainer.
+  
+  Gaps in the curve can be created by adding data points with NaN as key and value
+  (<tt>qQNaN()</tt> or <tt>std::numeric_limits<double>::quiet_NaN()</tt>) in between the two data points that shall be
+  separated.
+  
+  \section qcpcurve-appearance Changing the appearance
+  
+  The appearance of the curve is determined by the pen and the brush (\ref setPen, \ref setBrush).
+  
+  \section qcpcurve-usage Usage
+  
+  Like all data representing objects in QCustomPlot, the QCPCurve is a plottable
+  (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
+  (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
+  
+  Usually, you first create an instance:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcurve-creation-1
+  which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot instance takes
+  ownership of the plottable, so do not delete it manually but use QCustomPlot::removePlottable() instead.
+  The newly created plottable can be modified, e.g.:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcurve-creation-2

+  printed to the debug output (qDebug), the construction is not aborted, though.

+  The created QCPCurve is automatically registered with the QCustomPlot instance inferred from \a

+  \brief Groups multiple QCPBars together so they appear side by side
+  
+  \image html QCPBarsGroup.png
+  
+  When showing multiple QCPBars in one plot which have bars at identical keys, it may be desirable
+  to have them appearing next to each other at each key. This is what adding the respective QCPBars
+  plottables to a QCPBarsGroup achieves. (An alternative approach is to stack them on top of each
+  other, see \ref QCPBars::moveAbove.)
+  
+  \section qcpbarsgroup-usage Usage
+  
+  To add a QCPBars plottable to the group, create a new group and then add the respective bars
+  intances:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpbarsgroup-creation
+  Alternatively to appending to the group like shown above, you can also set the group on the
+  QCPBars plottable via \ref QCPBars::setBarsGroup.
+  
+  The spacing between the bars can be configured via \ref setSpacingType and \ref setSpacing. The
+  bars in this group appear in the plot in the order they were appended. To insert a bars plottable
+  at a certain index position, or to reposition a bars plottable which is already in the group, use
+  \ref insert.
+  
+  To remove specific bars from the group, use either \ref remove or call \ref
+  QCPBars::setBarsGroup "QCPBars::setBarsGroup(0)" on the respective bars plottable.
+  
+  To clear the entire group, call \ref clear, or simply delete the group.

+/*! \class QCPStatisticalBox
+  \brief A plottable representing a single statistical box in a plot.
+
+  \image html QCPStatisticalBox.png
+  
+  To plot data, assign it with the \ref setData or \ref addData functions. Alternatively, you can
+  also access and modify the data via the \ref data method, which returns a pointer to the internal
+  \ref QCPStatisticalBoxDataContainer.
+  
+  Additionally each data point can itself have a list of outliers, drawn as scatter points at the
+  key coordinate of the respective statistical box data point. They can either be set by using the
+  respective \ref addData(double,double,double,double,double,double,const QVector<double>&)
+  "addData" method or accessing the individual data points through \ref data, and setting the
+  <tt>QVector<double> outliers</tt> of the data points directly.
+  
+  \section qcpstatisticalbox-appearance Changing the appearance
+  
+  The appearance of each data point box, ranging from the lower to the upper quartile, is
+  controlled via \ref setPen and \ref setBrush. You may change the width of the boxes with \ref
+  setWidth in plot coordinates.
+
+  Each data point's visual representation also consists of two whiskers. Whiskers are the lines
+  which reach from the upper quartile to the maximum, and from the lower quartile to the minimum.
+  The appearance of the whiskers can be modified with: \ref setWhiskerPen, \ref setWhiskerBarPen,
+  \ref setWhiskerWidth. The whisker width is the width of the bar perpendicular to the whisker at
+  the top (for maximum) and bottom (for minimum). If the whisker pen is changed, make sure to set
+  the \c capStyle to \c Qt::FlatCap. Otherwise the backbone line might exceed the whisker bars by a
+  few pixels due to the pen cap being not perfectly flat.
+  
+  The median indicator line inside the box has its own pen, \ref setMedianPen.
+  
+  The outlier data points are drawn as normal scatter points. Their look can be controlled with
+  \ref setOutlierStyle
+  
+  \section qcpstatisticalbox-usage Usage
+  
+  Like all data representing objects in QCustomPlot, the QCPStatisticalBox is a plottable
+  (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
+  (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
+  
+  Usually, you first create an instance:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpstatisticalbox-creation-1
+  which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot instance takes
+  ownership of the plottable, so do not delete it manually but use QCustomPlot::removePlottable() instead.
+  The newly created plottable can be modified, e.g.:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpstatisticalbox-creation-2

+/*! \class QCPColorMapData
+  \brief Holds the two-dimensional data of a QCPColorMap plottable.
+  
+  This class is a data storage for \ref QCPColorMap. It holds a two-dimensional array, which \ref
+  QCPColorMap then displays as a 2D image in the plot, where the array values are represented by a
+  color, depending on the value.
+  
+  The size of the array can be controlled via \ref setSize (or \ref setKeySize, \ref setValueSize).
+  Which plot coordinates these cells correspond to can be configured with \ref setRange (or \ref
+  setKeyRange, \ref setValueRange).
+  
+  The data cells can be accessed in two ways: They can be directly addressed by an integer index
+  with \ref setCell. This is the fastest method. Alternatively, they can be addressed by their plot
+  coordinate with \ref setData. plot coordinate to cell index transformations and vice versa are
+  provided by the functions \ref coordToCell and \ref cellToCoord.
+  
+  A \ref QCPColorMapData also holds an on-demand two-dimensional array of alpha values which (if
+  allocated) has the same size as the data map. It can be accessed via \ref setAlpha, \ref
+  fillAlpha and \ref clearAlpha. The memory for the alpha map is only allocated if needed, i.e. on
+  the first call of \ref setAlpha. \ref clearAlpha restores full opacity and frees the alpha map.
+  
+  This class also buffers the minimum and maximum values that are in the data set, to provide
+  QCPColorMap::rescaleDataRange with the necessary information quickly. Setting a cell to a value
+  that is greater than the current maximum increases this maximum to the new value. However,
+  setting the cell that currently holds the maximum value to a smaller value doesn't decrease the
+  maximum again, because finding the true new maximum would require going through the entire data
+  array, which might be time consuming. The same holds for the data minimum. This functionality is
+  given by \ref recalculateDataBounds, such that you can decide when it is sensible to find the
+  true current minimum and maximum. The method QCPColorMap::rescaleDataRange offers a convenience
+  parameter \a recalculateDataBounds which may be set to true to automatically call \ref
+  recalculateDataBounds internally.

+/*! \class QCPColorMap
+  \brief A plottable representing a two-dimensional color map in a plot.
+
+  \image html QCPColorMap.png
+  
+  The data is stored in the class \ref QCPColorMapData, which can be accessed via the data()
+  method.
+  
+  A color map has three dimensions to represent a data point: The \a key dimension, the \a value
+  dimension and the \a data dimension. As with other plottables such as graphs, \a key and \a value
+  correspond to two orthogonal axes on the QCustomPlot surface that you specify in the QCPColorMap
+  constructor. The \a data dimension however is encoded as the color of the point at (\a key, \a
+  value).
+
+  Set the number of points (or \a cells) in the key/value dimension via \ref
+  QCPColorMapData::setSize. The plot coordinate range over which these points will be displayed is
+  specified via \ref QCPColorMapData::setRange. The first cell will be centered on the lower range
+  boundary and the last cell will be centered on the upper range boundary. The data can be set by
+  either accessing the cells directly with QCPColorMapData::setCell or by addressing the cells via
+  their plot coordinates with \ref QCPColorMapData::setData. If possible, you should prefer
+  setCell, since it doesn't need to do any coordinate transformation and thus performs a bit
+  better.
+  
+  The cell with index (0, 0) is at the bottom left, if the color map uses normal (i.e. not reversed)
+  key and value axes.
+  
+  To show the user which colors correspond to which \a data values, a \ref QCPColorScale is
+  typically placed to the right of the axis rect. See the documentation there for details on how to
+  add and use a color scale.
+  
+  \section qcpcolormap-appearance Changing the appearance
+  
+  The central part of the appearance is the color gradient, which can be specified via \ref
+  setGradient. See the documentation of \ref QCPColorGradient for details on configuring a color
+  gradient.
+  
+  The \a data range that is mapped to the colors of the gradient can be specified with \ref
+  setDataRange. To make the data range encompass the whole data set minimum to maximum, call \ref
+  rescaleDataRange.
+  
+  \section qcpcolormap-transparency Transparency
+  
+  Transparency in color maps can be achieved by two mechanisms. On one hand, you can specify alpha
+  values for color stops of the \ref QCPColorGradient, via the regular QColor interface. This will
+  cause the color map data which gets mapped to colors around those color stops to appear with the
+  accordingly interpolated transparency.
+  
+  On the other hand you can also directly apply an alpha value to each cell independent of its
+  data, by using the alpha map feature of \ref QCPColorMapData. The relevant methods are \ref
+  QCPColorMapData::setAlpha, QCPColorMapData::fillAlpha and \ref QCPColorMapData::clearAlpha().
+  
+  The two transparencies will be joined together in the plot and otherwise not interfere with each
+  other. They are mixed in a multiplicative matter, so an alpha of e.g. 50% (128/255) in both modes
+  simultaneously, will result in a total transparency of 25% (64/255).
+  
+  \section qcpcolormap-usage Usage
+  
+  Like all data representing objects in QCustomPlot, the QCPColorMap is a plottable
+  (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
+  (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
+  
+  Usually, you first create an instance:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolormap-creation-1
+  which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot instance takes
+  ownership of the plottable, so do not delete it manually but use QCustomPlot::removePlottable() instead.
+  The newly created plottable can be modified, e.g.:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolormap-creation-2
+  
+  \note The QCPColorMap always displays the data at equal key/value intervals, even if the key or
+  value axis is set to a logarithmic scaling. If you want to use QCPColorMap with logarithmic axes,
+  you shouldn't use the \ref QCPColorMapData::setData method as it uses a linear transformation to
+  determine the cell index. Rather directly access the cell index with \ref
+  QCPColorMapData::setCell.

+/*! \class QCPFinancial
+  \brief A plottable representing a financial stock chart
+
+  \image html QCPFinancial.png
+
+  This plottable represents time series data binned to certain intervals, mainly used for stock
+  charts. The two common representations OHLC (Open-High-Low-Close) bars and Candlesticks can be
+  set via \ref setChartStyle.
+
+  The data is passed via \ref setData as a set of open/high/low/close values at certain keys
+  (typically times). This means the data must be already binned appropriately. If data is only
+  available as a series of values (e.g. \a price against \a time), you can use the static
+  convenience function \ref timeSeriesToOhlc to generate binned OHLC-data which can then be passed
+  to \ref setData.
+
+  The width of the OHLC bars/candlesticks can be controlled with \ref setWidth and \ref
+  setWidthType. A typical choice is to set the width type to \ref wtPlotCoords (the default) and
+  the width to (or slightly less than) one time bin interval width.
+
+  \section qcpfinancial-appearance Changing the appearance
+
+  Charts can be either single- or two-colored (\ref setTwoColored). If set to be single-colored,
+  lines are drawn with the plottable's pen (\ref setPen) and fills with the brush (\ref setBrush).
+
+  If set to two-colored, positive changes of the value during an interval (\a close >= \a open) are
+  represented with a different pen and brush than negative changes (\a close < \a open). These can
+  be configured with \ref setPenPositive, \ref setPenNegative, \ref setBrushPositive, and \ref
+  setBrushNegative. In two-colored mode, the normal plottable pen/brush is ignored. Upon selection
+  however, the normal selected pen/brush (provided by the \ref selectionDecorator) is used,
+  irrespective of whether the chart is single- or two-colored.
+
+  \section qcpfinancial-usage Usage
+
+  Like all data representing objects in QCustomPlot, the QCPFinancial is a plottable
+  (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
+  (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
+
+  Usually, you first create an instance:
+
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpfinancial-creation-1
+  which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot
+  instance takes ownership of the plottable, so do not delete it manually but use
+  QCustomPlot::removePlottable() instead. The newly created plottable can be modified, e.g.:
+
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpfinancial-creation-2
+  Here we have used the static helper method \ref timeSeriesToOhlc, to turn a time-price data
+  series into a 24-hour binned open-high-low-close data series as QCPFinancial uses.

+  printed to the debug output (qDebug), the construction is not aborted, though.

+
+  \image html QCPErrorBars.png
+
+  The \ref QCPErrorBars plottable can be attached to other one-dimensional plottables (e.g. \ref
+  QCPGraph, \ref QCPCurve, \ref QCPBars, etc.) and equips them with error bars.
+
+  Use \ref setDataPlottable to define for which plottable the \ref QCPErrorBars shall display the
+  error bars. The orientation of the error bars can be controlled with \ref setErrorType.
+
+  By using \ref setData, you can supply the actual error data, either as symmetric error or
+  plus/minus asymmetric errors. \ref QCPErrorBars only stores the error data. The absolute
+  key/value position of each error bar will be adopted from the configured data plottable. The
+  error data of the \ref QCPErrorBars are associated one-to-one via their index to the data points
+  of the data plottable. You can directly access and manipulate the error bar data via \ref data.
+
+  Set either of the plus/minus errors to NaN (<tt>qQNaN()</tt> or
+  <tt>std::numeric_limits<double>::quiet_NaN()</tt>) to not show the respective error bar on the data point at
+  that index.
+
+  \section qcperrorbars-appearance Changing the appearance
+
+  The appearance of the error bars is defined by the pen (\ref setPen), and the width of the
+  whiskers (\ref setWhiskerWidth). Further, the error bar backbones may leave a gap around the data
+  point center to prevent that error bars are drawn too close to or even through scatter points.
+  This gap size can be controlled via \ref setSymbolGap.

+/*! \class QCPItemTracer
+  \brief Item that sticks to QCPGraph data points
+
+  \image html QCPItemTracer.png "Tracer example. Blue dotted circles are anchors, solid blue discs are positions."
+
+  The tracer can be connected with a QCPGraph via \ref setGraph. Then it will automatically adopt
+  the coordinate axes of the graph and update its \a position to be on the graph's data. This means
+  the key stays controllable via \ref setGraphKey, but the value will follow the graph data. If a
+  QCPGraph is connected, note that setting the coordinates of the tracer item directly via \a
+  position will have no effect because they will be overriden in the next redraw (this is when the
+  coordinate update happens).
+  
+  If the specified key in \ref setGraphKey is outside the key bounds of the graph, the tracer will
+  stay at the corresponding end of the graph.
+  
+  With \ref setInterpolating you may specify whether the tracer may only stay exactly on data
+  points or whether it interpolates data points linearly, if given a key that lies between two data
+  points of the graph.
+  
+  The tracer has different visual styles, see \ref setStyle. It is also possible to make the tracer
+  have no own visual appearance (set the style to \ref tsNone), and just connect other item
+  positions to the tracer \a position (used as an anchor) via \ref
+  QCPItemPosition::setParentAnchor.
+  
+  \note The tracer position is only automatically updated upon redraws. So when the data of the
+  graph changes and immediately afterwards (without a redraw) the position coordinates of the
+  tracer are retrieved, they will not reflect the updated data of the graph. In this case \ref
+  updatePosition must be called manually, prior to reading the tracer coordinates.

-  \brief The abstract base class for paint buffers, which define the rendering backend
-
-  This abstract base class defines the basic interface that a paint buffer needs to provide in
-  order to be usable by QCustomPlot.
-
-  A paint buffer manages both a surface to draw onto, and the matching paint device. The size of
-  the surface can be changed via \ref setSize. External classes (\ref QCustomPlot and \ref
-  QCPLayer) request a painter via \ref startPainting and then perform the draw calls. Once the
-  painting is complete, \ref donePainting is called, so the paint buffer implementation can do
-  clean up if necessary. Before rendering a frame, each paint buffer is usually filled with a color
-  using \ref clear (usually the color is \c Qt::transparent), to remove the contents of the
-  previous frame.
-
-  The simplest paint buffer implementation is \ref QCPPaintBufferPixmap which allows regular
-  software rendering via the raster engine. Hardware accelerated rendering via pixel buffers and
-  frame buffer objects is provided by \ref QCPPaintBufferGlPbuffer and \ref QCPPaintBufferGlFbo.
-  They are used automatically if \ref QCustomPlot::setOpenGl is enabled.

-/*! \class QCPLayer
-  \brief A layer that may contain objects, to control the rendering order
-
-  The Layering system of QCustomPlot is the mechanism to control the rendering order of the
-  elements inside the plot.
-
-  It is based on the two classes QCPLayer and QCPLayerable. QCustomPlot holds an ordered list of
-  one or more instances of QCPLayer (see QCustomPlot::addLayer, QCustomPlot::layer,
-  QCustomPlot::moveLayer, etc.). When replotting, QCustomPlot goes through the list of layers
-  bottom to top and successively draws the layerables of the layers into the paint buffer(s).
-
-  A QCPLayer contains an ordered list of QCPLayerable instances. QCPLayerable is an abstract base
-  class from which almost all visible objects derive, like axes, grids, graphs, items, etc.
-
-  \section qcplayer-defaultlayers Default layers
-
-  Initially, QCustomPlot has six layers: "background", "grid", "main", "axes", "legend" and
-  "overlay" (in that order). On top is the "overlay" layer, which only contains the QCustomPlot's
-  selection rect (\ref QCustomPlot::selectionRect). The next two layers "axes" and "legend" contain
-  the default axes and legend, so they will be drawn above plottables. In the middle, there is the
-  "main" layer. It is initially empty and set as the current layer (see
-  QCustomPlot::setCurrentLayer). This means, all new plottables, items etc. are created on this
-  layer by default. Then comes the "grid" layer which contains the QCPGrid instances (which belong
-  tightly to QCPAxis, see \ref QCPAxis::grid). The Axis rect background shall be drawn behind
-  everything else, thus the default QCPAxisRect instance is placed on the "background" layer. Of
-  course, the layer affiliation of the individual objects can be changed as required (\ref
-  QCPLayerable::setLayer).
-
-  \section qcplayer-ordering Controlling the rendering order via layers
-
-  Controlling the ordering of layerables in the plot is easy: Create a new layer in the position
-  you want the layerable to be in, e.g. above "main", with \ref QCustomPlot::addLayer. Then set the
-  current layer with \ref QCustomPlot::setCurrentLayer to that new layer and finally create the
-  objects normally. They will be placed on the new layer automatically, due to the current layer
-  setting. Alternatively you could have also ignored the current layer setting and just moved the
-  objects with \ref QCPLayerable::setLayer to the desired layer after creating them.
-
-  It is also possible to move whole layers. For example, If you want the grid to be shown in front
-  of all plottables/items on the "main" layer, just move it above "main" with
-  QCustomPlot::moveLayer.
-
-  The rendering order within one layer is simply by order of creation or insertion. The item
-  created last (or added last to the layer), is drawn on top of all other objects on that layer.
-
-  When a layer is deleted, the objects on it are not deleted with it, but fall on the layer below
-  the deleted layer, see QCustomPlot::removeLayer.
-
-  \section qcplayer-buffering Replotting only a specific layer
-
-  If the layer mode (\ref setMode) is set to \ref lmBuffered, you can replot only this specific
-  layer by calling \ref replot. In certain situations this can provide better replot performance,
-  compared with a full replot of all layers. Upon creation of a new layer, the layer mode is
-  initialized to \ref lmLogical. The only layer that is set to \ref lmBuffered in a new \ref
-  QCustomPlot instance is the "overlay" layer, containing the selection rect.

-  
-  This function applies the default antialiasing setting to the specified \a painter, using the
-  function \ref applyAntialiasingHint. It is the antialiasing state the painter is put in, when
-  \ref draw is called on the layerable. If the layerable has multiple entities whose antialiasing
-  setting may be specified individually, this function should set the antialiasing state of the
-  most prominent entity. In this case however, the \ref draw function usually calls the specialized
-  versions of this function before drawing each entity, effectively overriding the setting of the
-  default antialiasing hint.
-  
-  <b>First example:</b> QCPGraph has multiple entities that have an antialiasing setting: The graph
-  line, fills and scatters. Those can be configured via QCPGraph::setAntialiased,
-  QCPGraph::setAntialiasedFill and QCPGraph::setAntialiasedScatters. Consequently, there isn't only
-  the QCPGraph::applyDefaultAntialiasingHint function (which corresponds to the graph line's
-  antialiasing), but specialized ones like QCPGraph::applyFillAntialiasingHint and
-  QCPGraph::applyScattersAntialiasingHint. So before drawing one of those entities, QCPGraph::draw
-  calls the respective specialized applyAntialiasingHint function.
-  
-  <b>Second example:</b> QCPItemLine consists only of a line so there is only one antialiasing
-  setting which can be controlled with QCPItemLine::setAntialiased. (This function is inherited by
-  all layerables. The specialized functions, as seen on QCPGraph, must be added explicitly to the
-  respective layerable subclass.) Consequently it only has the normal
-  QCPItemLine::applyDefaultAntialiasingHint. The \ref QCPItemLine::draw function doesn't need to
-  care about setting any antialiasing states, because the default antialiasing hint is already set
-  on the painter when the \ref draw function is called, and that's the state it wants to draw the

-  \a event is the mouse event that caused the selection. \a additive indicates, whether the user

-  \a selectionStateChanged is an output parameter. If the pointer is non-null, this function must

-  was actually changed. For layerables that only are selectable as a whole and not in parts, this
-  is simple: if \a additive is true, \a selectionStateChanged must also be set to true, because the

-  \brief Describes a data range given by begin and end index
-  
-  QCPDataRange holds two integers describing the begin (\ref setBegin) and end (\ref setEnd) index
-  of a contiguous set of data points. The end index points to the data point above the last data point that's part of
-  the data range, similarly to the nomenclature used in standard iterators.
-  
-  Data Ranges are not bound to a certain plottable, thus they can be freely exchanged, created and
-  modified. If a non-contiguous data set shall be described, the class \ref QCPDataSelection is
-  used, which holds and manages multiple instances of \ref QCPDataRange. In most situations, \ref
-  QCPDataSelection is thus used.
-  
-  Both \ref QCPDataRange and \ref QCPDataSelection offer convenience methods to work with them,
-  e.g. \ref bounded, \ref expanded, \ref intersects, \ref intersection, \ref adjusted, \ref
-  contains. Further, addition and subtraction operators (defined in \ref QCPDataSelection) can be
-  used to join/subtract data ranges and data selections (or mixtures), to retrieve a corresponding
-  \ref QCPDataSelection.
-  
-  %QCustomPlot's \ref dataselection "data selection mechanism" is based on \ref QCPDataSelection and
-  QCPDataRange.
-  
-  \note Do not confuse \ref QCPDataRange with \ref QCPRange. A \ref QCPRange describes an interval
-  in floating point plot coordinates, e.g. the current axis range.

-/*! \class QCPDataSelection
-  \brief Describes a data set by holding multiple QCPDataRange instances
-  
-  QCPDataSelection manages multiple instances of QCPDataRange in order to represent any (possibly
-  disjoint) set of data selection.
-  
-  The data selection can be modified with addition and subtraction operators which take
-  QCPDataSelection and QCPDataRange instances, as well as methods such as \ref addDataRange and
-  \ref clear. Read access is provided by \ref dataRange, \ref dataRanges, \ref dataRangeCount, etc.
-  
-  The method \ref simplify is used to join directly adjacent or even overlapping QCPDataRange
-  instances. QCPDataSelection automatically simplifies when using the addition/subtraction
-  operators. The only case when \ref simplify is left to the user, is when calling \ref
-  addDataRange, with the parameter \a simplify explicitly set to false. This is useful if many data
-  ranges will be added to the selection successively and the overhead for simplifying after each
-  iteration shall be avoided. In this case, you should make sure to call \ref simplify after
-  completing the operation.
-  
-  Use \ref enforceType to bring the data selection into a state complying with the constraints for
-  selections defined in \ref QCP::SelectionType.
-  
-  %QCustomPlot's \ref dataselection "data selection mechanism" is based on QCPDataSelection and
-  QCPDataRange.

-  
-  QCPSelectionRect is used by QCustomPlot when the \ref QCustomPlot::setSelectionRectMode is not

-  emits the corresponding signals \ref started, \ref changed, \ref canceled, and \ref accepted.
-  
-  The QCustomPlot instance connects own slots to the current selection rect instance, in order to
-  react to an accepted selection rect interaction accordingly.
-  
-  \ref isActive can be used to check whether the selection rect is currently active. An ongoing
-  selection interaction can be cancelled programmatically via calling \ref cancel at any time.
-  
-  The appearance of the selection rect can be controlled via \ref setPen and \ref setBrush.
-
-  If you wish to provide custom behaviour, e.g. a different visual representation of the selection
-  rect (\ref QCPSelectionRect::draw), you can subclass QCPSelectionRect and pass an instance of

-/*! \class QCPMarginGroup
-  \brief A margin group allows synchronization of margin sides if working with multiple layout elements.
-  
-  QCPMarginGroup allows you to tie a margin side of two or more layout elements together, such that
-  they will all have the same size, based on the largest required margin in the group.
-  
-  \n
-  \image html QCPMarginGroup.png "Demonstration of QCPMarginGroup"
-  \n
-  
-  In certain situations it is desirable that margins at specific sides are synchronized across
-  layout elements. For example, if one QCPAxisRect is below another one in a grid layout, it will
-  provide a cleaner look to the user if the left and right margins of the two axis rects are of the
-  same size. The left axis of the top axis rect will then be at the same horizontal position as the
-  left axis of the lower axis rect, making them appear aligned. The same applies for the right
-  axes. This is what QCPMarginGroup makes possible.
-  
-  To add/remove a specific side of a layout element to/from a margin group, use the \ref
-  QCPLayoutElement::setMarginGroup method. To completely break apart the margin group, either call
-  \ref clear, or just delete the margin group.
-  
-  \section QCPMarginGroup-example Example
-  
-  First create a margin group:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpmargingroup-creation-1
-  Then set this group on the layout element sides:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpmargingroup-creation-2
-  Here, we've used the first two axis rects of the plot and synchronized their left margins with
-  each other and their right margins with each other.

-/*! \class QCPLayoutElement
-  \brief The abstract base class for all objects that form \ref thelayoutsystem "the layout system".
-  
-  This is an abstract base class. As such, it can't be instantiated directly, rather use one of its subclasses.
-  
-  A Layout element is a rectangular object which can be placed in layouts. It has an outer rect
-  (QCPLayoutElement::outerRect) and an inner rect (\ref QCPLayoutElement::rect). The difference
-  between outer and inner rect is called its margin. The margin can either be set to automatic or
-  manual (\ref setAutoMargins) on a per-side basis. If a side is set to manual, that margin can be
-  set explicitly with \ref setMargins and will stay fixed at that value. If it's set to automatic,
-  the layout element subclass will control the value itself (via \ref calculateAutoMargin).
-  
-  Layout elements can be placed in layouts (base class QCPLayout) like QCPLayoutGrid. The top level
-  layout is reachable via \ref QCustomPlot::plotLayout, and is a \ref QCPLayoutGrid. Since \ref
-  QCPLayout itself derives from \ref QCPLayoutElement, layouts can be nested.
-  
-  Thus in QCustomPlot one can divide layout elements into two categories: The ones that are
-  invisible by themselves, because they don't draw anything. Their only purpose is to manage the
-  position and size of other layout elements. This category of layout elements usually use
-  QCPLayout as base class. Then there is the category of layout elements which actually draw
-  something. For example, QCPAxisRect, QCPLegend and QCPTextElement are of this category. This does
-  not necessarily mean that the latter category can't have child layout elements. QCPLegend for
-  instance, actually derives from QCPLayoutGrid and the individual legend items are child layout
-  elements in the grid layout.

-  area is used to display peripheral graphics while the main content is in the inner rect. This is

-/*! \class QCPLayout
-  \brief The abstract base class for layouts
-  
-  This is an abstract base class for layout elements whose main purpose is to define the position
-  and size of other child layout elements. In most cases, layouts don't draw anything themselves
-  (but there are exceptions to this, e.g. QCPLegend).
-  
-  QCPLayout derives from QCPLayoutElement, and thus can itself be nested in other layouts.
-  
-  QCPLayout introduces a common interface for accessing and manipulating the child elements. Those
-  functions are most notably \ref elementCount, \ref elementAt, \ref takeAt, \ref take, \ref
-  simplify, \ref removeAt, \ref remove and \ref clear. Individual subclasses may add more functions
-  to this interface which are more specialized to the form of the layout. For example, \ref
-  QCPLayoutGrid adds functions that take row and column indices to access cells of the layout grid
-  more conveniently.
-  
-  Since this is an abstract base class, you can't instantiate it directly. Rather use one of its
-  subclasses like QCPLayoutGrid or QCPLayoutInset.
-  
-  For a general introduction to the layout system, see the dedicated documentation page \ref
-  thelayoutsystem "The Layout System".

-  
-  For every ending a line-like item has, an instance of this class exists. For example, QCPItemLine
-  has two endings which can be set with QCPItemLine::setHead and QCPItemLine::setTail.
- 
-  The styles themselves are defined via the enum QCPLineEnding::EndingStyle. Most decorations can
-  be modified regarding width and length, see \ref setWidth and \ref setLength. The direction of
-  the ending decoration (e.g. direction an arrow is pointing) is controlled by the line-like item.
-  For example, when both endings of a QCPItemLine are set to be arrows, they will point to opposite
-  directions, e.g. "outward". This can be changed by \ref setInverted, which would make the
-  respective arrow point inward.
-  
-  Note that due to the overloaded QCPLineEnding constructor, you may directly specify a
-  QCPLineEnding::EndingStyle where actually a QCPLineEnding is expected, e.g.

-/*! \class QCPAxisTicker
-  \brief The base class tick generator used by QCPAxis to create tick positions and tick labels
-  
-  Each QCPAxis has an internal QCPAxisTicker (or a subclass) in order to generate tick positions
-  and tick labels for the current axis range. The ticker of an axis can be set via \ref
-  QCPAxis::setTicker. Since that method takes a <tt>QSharedPointer<QCPAxisTicker></tt>, multiple
-  axes can share the same ticker instance.
-  
-  This base class generates normal tick coordinates and numeric labels for linear axes. It picks a
-  reasonable tick step (the separation between ticks) which results in readable tick labels. The
-  number of ticks that should be approximately generated can be set via \ref setTickCount.
-  Depending on the current tick step strategy (\ref setTickStepStrategy), the algorithm either
-  sacrifices readability to better match the specified tick count (\ref
-  QCPAxisTicker::tssMeetTickCount) or relaxes the tick count in favor of better tick steps (\ref
-  QCPAxisTicker::tssReadability), which is the default.
-  
-  The following more specialized axis ticker subclasses are available, see details in the
-  respective class documentation:

-  \section axisticker-subclassing Creating own axis tickers
-  
-  Creating own axis tickers can be achieved very easily by sublassing QCPAxisTicker and
-  reimplementing some or all of the available virtual methods.
-
-  In the simplest case you might wish to just generate different tick steps than the other tickers,
-  so you only reimplement the method \ref getTickStep. If you additionally want control over the
-  string that will be shown as tick label, reimplement \ref getTickLabel.
-  
-  If you wish to have complete control, you can generate the tick vectors and tick label vectors
-  yourself by reimplementing \ref createTickVector and \ref createLabelVector. The default
-  implementations use the previously mentioned virtual methods \ref getTickStep and \ref
-  getTickLabel, but your reimplementations don't necessarily need to do so. For example in the case
-  of unequal tick steps, the method \ref getTickStep loses its usefulness and can be ignored.
-  
-  The sub tick count between major ticks can be controlled with \ref getSubTickCount. Full sub tick
-  placement control is obtained by reimplementing \ref createSubTickVector.
-  
-  See the documentation of all these virtual methods in QCPAxisTicker for detailed information
-  about the parameters and expected return values.

-/*! \class QCPAxisTickerDateTime
-  \brief Specialized axis ticker for calendar dates and times as axis ticks
-  
-  \image html axisticker-datetime.png
-  
-  This QCPAxisTicker subclass generates ticks that correspond to real calendar dates and times. The
-  plot axis coordinate is interpreted as Unix Time, so seconds since Epoch (January 1, 1970, 00:00
-  UTC). This is also used for example by QDateTime in the <tt>toTime_t()/setTime_t()</tt> methods
-  with a precision of one second. Since Qt 4.7, millisecond accuracy can be obtained from QDateTime
-  by using <tt>QDateTime::fromMSecsSinceEpoch()/1000.0</tt>. The static methods \ref dateTimeToKey
-  and \ref keyToDateTime conveniently perform this conversion achieving a precision of one
-  millisecond on all Qt versions.
-  
-  The format of the date/time display in the tick labels is controlled with \ref setDateTimeFormat.
-  If a different time spec (time zone) shall be used, see \ref setDateTimeSpec.
-  
-  This ticker produces unequal tick spacing in order to provide intuitive date and time-of-day
-  ticks. For example, if the axis range spans a few years such that there is one tick per year,
-  ticks will be positioned on 1. January of every year. This is intuitive but, due to leap years,
-  will result in slightly unequal tick intervals (visually unnoticeable). The same can be seen in
-  the image above: even though the number of days varies month by month, this ticker generates
-  ticks on the same day of each month.
-

-/*! \class QCPAxisTickerTime
-  \brief Specialized axis ticker for time spans in units of milliseconds to days
-  
-  \image html axisticker-time.png
-  
-  This QCPAxisTicker subclass generates ticks that corresponds to time intervals.
-  
-  The format of the time display in the tick labels is controlled with \ref setTimeFormat and \ref
-  setFieldWidth. The time coordinate is in the unit of seconds with respect to the time coordinate
-  zero. Unlike with QCPAxisTickerDateTime, the ticks don't correspond to a specific calendar date
-  and time.
-  
-  The time can be displayed in milliseconds, seconds, minutes, hours and days. Depending on the
-  largest available unit in the format specified with \ref setTimeFormat, any time spans above will
-  be carried in that largest unit. So for example if the format string is "%m:%s" and a tick at
-  coordinate value 7815 (being 2 hours, 10 minutes and 15 seconds) is created, the resulting tick
-  label will show "130:15" (130 minutes, 15 seconds). If the format string is "%h:%m:%s", the hour
-  unit will be used and the label will thus be "02:10:15". Negative times with respect to the axis
-  zero will carry a leading minus sign.
-  
-  The ticker can be created and assigned to an axis like this:
-  \snippet documentation/doc-image-generator/mainwindow.cpp axistickertime-creation
-  
-  Here is an example of a time axis providing time information in days, hours and minutes. Due to
-  the axis range spanning a few days and the wanted tick count (\ref setTickCount), the ticker
-  decided to use tick steps of 12 hours:
-  
-  \image html axisticker-time2.png
-  
-  The format string for this example is
-  \snippet documentation/doc-image-generator/mainwindow.cpp axistickertime-creation-2
-  
-  \note If you rather wish to display calendar dates and times, have a look at QCPAxisTickerDateTime
-  instead.

-  
-  This QCPAxisTicker subclass generates ticks with a fixed tick step set with \ref setTickStep. It
-  is also possible to allow integer multiples and integer powers of the specified tick step with

-  
-  A typical application of this ticker is to make an axis only display integers, by setting the
-  tick step of the ticker to 1.0 and the scale strategy to \ref ssMultiples.
-  
-  Another case is when a certain number has a special meaning and axis ticks should only appear at
-  multiples of that value. In this case you might also want to consider \ref QCPAxisTickerPi
-  because despite the name it is not limited to only pi symbols/values.

-/*! \class QCPGrid
-  \brief Responsible for drawing the grid of a QCPAxis.
-  
-  This class is tightly bound to QCPAxis. Every axis owns a grid instance and uses it to draw the
-  grid lines, sub grid lines and zero-line. You can interact with the grid of an axis via \ref
-  QCPAxis::grid. Normally, you don't need to create an instance of QCPGrid yourself.
-  
-  The axis and grid drawing was split into two classes to allow them to be placed on different
-  layers (both QCPAxis and QCPGrid inherit from QCPLayerable). Thus it is possible to have the grid
-  in the background and the axes in the foreground, and any plottables/items in between. This
-  described situation is the default setup, see the QCPLayer documentation.

-  
-  \a formatCode is a string of one, two or three characters. The first character is identical to
-  the normal format code used by Qt. In short, this means: 'e'/'E' scientific format, 'f' fixed
-  format, 'g'/'G' scientific or fixed, whichever is shorter.
-  
-  The second and third characters are optional and specific to QCustomPlot:\n
-  If the first char was 'e' or 'g', numbers are/might be displayed in the scientific format, e.g.
-  "5.5e9", which is ugly in a plot. So when the second char of \a formatCode is set to 'b' (for
-  "beautiful"), those exponential numbers are formatted in a more natural way, i.e. "5.5
-  [multiplication sign] 10 [superscript] 9". By default, the multiplication sign is a centered dot.
-  If instead a cross should be shown (as is usual in the USA), the third char of \a formatCode can
-  be set to 'c'. The inserted multiplication signs are the UTF-8 characters 215 (0xD7) for the
-  cross and 183 (0xB7) for the dot.
-  
-  Examples for \a formatCode:
-  \li \c g normal format code behaviour. If number is small, fixed format is used, if number is large,
-  normal scientific format is used
-  \li \c gb If number is small, fixed format is used, if number is large, scientific format is used with
-  beautifully typeset decimal powers and a dot as multiplication sign
-  \li \c ebc All numbers are in scientific format with beautifully typeset decimal power and a cross as
-  multiplication sign
-  \li \c fb illegal format code, since fixed format doesn't support (or need) beautifully typeset decimal
-  powers. Format code will be reduced to 'f'.
-  \li \c hello illegal format code, since first char is not 'e', 'E', 'f', 'g' or 'G'. Current format
-  code will not be changed.

-/*! \class QCPScatterStyle
-  \brief Represents the visual appearance of scatter points
-  
-  This class holds information about shape, color and size of scatter points. In plottables like
-  QCPGraph it is used to store how scatter points shall be drawn. For example, \ref
-  QCPGraph::setScatterStyle takes a QCPScatterStyle instance.
-  
-  A scatter style consists of a shape (\ref setShape), a line color (\ref setPen) and possibly a
-  fill (\ref setBrush), if the shape provides a fillable area. Further, the size of the shape can
-  be controlled with \ref setSize.
-
-  \section QCPScatterStyle-defining Specifying a scatter style
-  
-  You can set all these configurations either by calling the respective functions on an instance:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpscatterstyle-creation-1
-  
-  Or you can use one of the various constructors that take different parameter combinations, making
-  it easy to specify a scatter style in a single call, like so:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpscatterstyle-creation-2
-  
-  \section QCPScatterStyle-undefinedpen Leaving the color/pen up to the plottable
-  
-  There are two constructors which leave the pen undefined: \ref QCPScatterStyle() and \ref
-  QCPScatterStyle(ScatterShape shape, double size). If those constructors are used, a call to \ref
-  isPenDefined will return false. It leads to scatter points that inherit the pen from the
-  plottable that uses the scatter style. Thus, if such a scatter style is passed to QCPGraph, the line
-  color of the graph (\ref QCPGraph::setPen) will be used by the scatter points. This makes
-  it very convenient to set up typical scatter settings:
-  
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpscatterstyle-shortcreation
-
-  Notice that it wasn't even necessary to explicitly call a QCPScatterStyle constructor. This works
-  because QCPScatterStyle provides a constructor that can transform a \ref ScatterShape directly
-  into a QCPScatterStyle instance (that's the \ref QCPScatterStyle(ScatterShape shape, double size)
-  constructor with a default for \a size). In those cases, C++ allows directly supplying a \ref
-  ScatterShape, where actually a QCPScatterStyle is expected.
-  
-  \section QCPScatterStyle-custompath-and-pixmap Custom shapes and pixmaps
-  
-  QCPScatterStyle supports drawing custom shapes and arbitrary pixmaps as scatter points.
-
-  For custom shapes, you can provide a QPainterPath with the desired shape to the \ref
-  setCustomPath function or call the constructor that takes a painter path. The scatter shape will
-  automatically be set to \ref ssCustom.
-  
-  For pixmaps, you call \ref setPixmap with the desired QPixmap. Alternatively you can use the
-  constructor that takes a QPixmap. The scatter shape will automatically be set to \ref ssPixmap.
-  Note that \ref setSize does not influence the appearance of the pixmap.

-  are \ref QCPScatterStyle() and \ref QCPScatterStyle(ScatterShape shape, double size). If the pen
-  is undefined, the pen of the respective plottable will be used for drawing scatters.

-/*! \class QCPSelectionDecorator
-  \brief Controls how a plottable's data selection is drawn
-  
-  Each \ref QCPAbstractPlottable instance has one \ref QCPSelectionDecorator (accessible via \ref
-  QCPAbstractPlottable::selectionDecorator) and uses it when drawing selected segments of its data.
-  
-  The selection decorator controls both pen (\ref setPen) and brush (\ref setBrush), as well as the
-  scatter style (\ref setScatterStyle) if the plottable draws scatters. Since a \ref
-  QCPScatterStyle is itself composed of different properties such as color shape and size, the
-  decorator allows specifying exactly which of those properties shall be used for the selected data
-  point, via \ref setUsedScatterProperties.
-  
-  A \ref QCPSelectionDecorator subclass instance can be passed to a plottable via \ref
-  QCPAbstractPlottable::setSelectionDecorator, allowing greater customizability of the appearance
-  of selected segments.
-  
-  Use \ref copyFrom to easily transfer the settings of one decorator to another one. This is
-  especially useful since plottables take ownership of the passed selection decorator, and thus the
-  same decorator instance can not be passed to multiple plottables.
-  
-  Selection decorators can also themselves perform drawing operations by reimplementing \ref
-  drawDecoration, which is called by the plottable's draw method. The base class \ref
-  QCPSelectionDecorator does not make use of this however. For example, \ref
-  QCPSelectionDecoratorBracket draws brackets around selected data segments.

-/*! \class QCPAbstractPlottable
-  \brief The abstract base class for all data representing objects in a plot.
-
-  It defines a very basic interface like name, pen, brush, visibility etc. Since this class is
-  abstract, it can't be instantiated. Use one of the subclasses or create a subclass yourself to
-  create new ways of displaying data (see "Creating own plottables" below). Plottables that display
-  one-dimensional data (i.e. data points have a single key dimension and one or multiple values at
-  each key) are based off of the template subclass \ref QCPAbstractPlottable1D, see details
-  there.
-  
-  All further specifics are in the subclasses, for example:
-  \li A normal graph with possibly a line and/or scatter points \ref QCPGraph
-  (typically created with \ref QCustomPlot::addGraph)
-  \li A parametric curve: \ref QCPCurve
-  \li A bar chart: \ref QCPBars
-  \li A statistical box plot: \ref QCPStatisticalBox
-  \li A color encoded two-dimensional map: \ref QCPColorMap
-  \li An OHLC/Candlestick chart: \ref QCPFinancial
-  
-  \section plottables-subclassing Creating own plottables
-  
-  Subclassing directly from QCPAbstractPlottable is only recommended if you wish to display
-  two-dimensional data like \ref QCPColorMap, i.e. two logical key dimensions and one (or more)
-  data dimensions. If you want to display data with only one logical key dimension, you should
-  rather derive from \ref QCPAbstractPlottable1D.
-  
-  If subclassing QCPAbstractPlottable directly, these are the pure virtual functions you must
-  implement:
-  \li \ref selectTest
-  \li \ref draw
-  \li \ref drawLegendIcon
-  \li \ref getKeyRange
-  \li \ref getValueRange
-  
-  See the documentation of those functions for what they need to do.
-  
-  For drawing your plot, you can use the \ref coordsToPixels functions to translate a point in plot
-  coordinates to pixel coordinates. This function is quite convenient, because it takes the
-  orientation of the key and value axes into account for you (x and y are swapped when the key axis
-  is vertical and the value axis horizontal). If you are worried about performance (i.e. you need
-  to translate many points in a loop like QCPGraph), you can directly use \ref
-  QCPAxis::coordToPixel. However, you must then take care about the orientation of the axis
-  yourself.
-  
-  Here are some important members you inherit from QCPAbstractPlottable:
-  <table>
-  <tr>
-    <td>QCustomPlot *\b mParentPlot</td>
-    <td>A pointer to the parent QCustomPlot instance. The parent plot is inferred from the axes that are passed in the constructor.</td>
-  </tr><tr>
-    <td>QString \b mName</td>
-    <td>The name of the plottable.</td>
-  </tr><tr>
-    <td>QPen \b mPen</td>
-    <td>The generic pen of the plottable. You should use this pen for the most prominent data representing lines in the plottable
-        (e.g QCPGraph uses this pen for its graph lines and scatters)</td>
-  </tr><tr>
-    <td>QBrush \b mBrush</td>
-    <td>The generic brush of the plottable. You should use this brush for the most prominent fillable structures in the plottable
-        (e.g. QCPGraph uses this brush to control filling under the graph)</td>
-  </tr><tr>
-    <td>QPointer<\ref QCPAxis> \b mKeyAxis, \b mValueAxis</td>
-    <td>The key and value axes this plottable is attached to. Call their QCPAxis::coordToPixel functions to translate coordinates
-        to pixels in either the key or value dimension. Make sure to check whether the pointer is null before using it. If one of
-        the axes is null, don't draw the plottable.</td>
-  </tr><tr>
-    <td>\ref QCPSelectionDecorator \b mSelectionDecorator</td>
-    <td>The currently set selection decorator which specifies how selected data of the plottable shall be drawn and decorated.
-        When drawing your data, you must consult this decorator for the appropriate pen/brush before drawing unselected/selected data segments.
-        Finally, you should call its \ref QCPSelectionDecorator::drawDecoration method at the end of your \ref draw implementation.</td>
-  </tr><tr>
-    <td>\ref QCP::SelectionType \b mSelectable</td>
-    <td>In which composition, if at all, this plottable's data may be selected. Enforcing this setting on the data selection is done
-        by QCPAbstractPlottable automatically.</td>
-  </tr><tr>
-    <td>\ref QCPDataSelection \b mSelection</td>
-    <td>Holds the current selection state of the plottable's data, i.e. the selected data ranges (\ref QCPDataRange).</td>

-  For example, a QCPItemRect is defined by its positions \a topLeft and \a bottomRight.
-  Additionally it has various anchors like \a top, \a topRight or \a bottomLeft etc. So you can
-  attach the \a start (which is a QCPItemPosition) of a QCPItemLine to one of the anchors by
-  calling QCPItemPosition::setParentAnchor on \a start, passing the wanted anchor of the
-  QCPItemRect. This way the start of the line will now always follow the respective anchor location
-  on the rect item.
-  
-  Note that QCPItemPosition derives from QCPItemAnchor, so every position can also serve as an
-  anchor to other positions.
-  
-  To learn how to provide anchors in your own item subclasses, see the subclassing section of the
-  QCPAbstractItem documentation.

-/*! \class QCPItemPosition
-  \brief Manages the position of an item.
-  
-  Every item has at least one public QCPItemPosition member pointer which provides ways to position the
-  item on the QCustomPlot surface. Some items have multiple positions, for example QCPItemRect has two:
-  \a topLeft and \a bottomRight.
-
-  QCPItemPosition has a type (\ref PositionType) that can be set with \ref setType. This type
-  defines how coordinates passed to \ref setCoords are to be interpreted, e.g. as absolute pixel
-  coordinates, as plot coordinates of certain axes, etc. For more advanced plots it is also
-  possible to assign different types per X/Y coordinate of the position (see \ref setTypeX, \ref
-  setTypeY). This way an item could be positioned at a fixed pixel distance from the top in the Y
-  direction, while following a plot coordinate in the X direction.
-
-  A QCPItemPosition may have a parent QCPItemAnchor, see \ref setParentAnchor. This way you can tie
-  multiple items together. If the QCPItemPosition has a parent, its coordinates (\ref setCoords)
-  are considered to be absolute pixels in the reference frame of the parent anchor, where (0, 0)
-  means directly ontop of the parent anchor. For example, You could attach the \a start position of
-  a QCPItemLine to the \a bottom anchor of a QCPItemText to make the starting point of the line
-  always be centered under the text label, no matter where the text is moved to. For more advanced
-  plots, it is possible to assign different parent anchors per X/Y coordinate of the position, see
-  \ref setParentAnchorX, \ref setParentAnchorY. This way an item could follow another item in the X
-  direction but stay at a fixed position in the Y direction. Or even follow item A in X, and item B
-  in Y.
-
-  Note that every QCPItemPosition inherits from QCPItemAnchor and thus can itself be used as parent
-  anchor for other positions.
-
-  To set the apparent pixel position on the QCustomPlot surface directly, use \ref setPixelPosition. This
-  works no matter what type this QCPItemPosition is or what parent-child situation it is in, as \ref
-  setPixelPosition transforms the coordinates appropriately, to make the position appear at the specified
-  pixel values.

-  Sets the type of the position. The type defines how the coordinates passed to \ref setCoords

-
-  \li The position is regarded as a point in plot coordinates. This corresponds to \ref ptPlotCoords
-  and requires two axes that define the plot coordinate system. They can be specified with \ref setAxes.
-  By default, the QCustomPlot's x- and yAxis are used.

-  documentation of \ref PositionType for details. For \ref ptAxisRectRatio, note that you can specify
-  the axis rect with \ref setAxisRect. By default this is set to the main axis rect.
-  
-  Note that the position type \ref ptPlotCoords is only available (and sensible) when the position
-  has no parent anchor (\ref setParentAnchor).

-/*! \class QCPAbstractItem
-  \brief The abstract base class for all items in a plot.
-  
-  In QCustomPlot, items are supplemental graphical elements that are neither plottables
-  (QCPAbstractPlottable) nor axes (QCPAxis). While plottables are always tied to two axes and thus
-  plot coordinates, items can also be placed in absolute coordinates independent of any axes. Each
-  specific item has at least one QCPItemPosition member which controls the positioning. Some items
-  are defined by more than one coordinate and thus have two or more QCPItemPosition members (For
-  example, QCPItemRect has \a topLeft and \a bottomRight).
-  
-  This abstract base class defines a very basic interface like visibility and clipping. Since this
-  class is abstract, it can't be instantiated. Use one of the subclasses or create a subclass
-  yourself to create new items.
-  
-  The built-in items are:
-  <table>
-  <tr><td>QCPItemLine</td><td>A line defined by a start and an end point. May have different ending styles on each side (e.g. arrows).</td></tr>
-  <tr><td>QCPItemStraightLine</td><td>A straight line defined by a start and a direction point. Unlike QCPItemLine, the straight line is infinitely long and has no endings.</td></tr>
-  <tr><td>QCPItemCurve</td><td>A curve defined by start, end and two intermediate control points. May have different ending styles on each side (e.g. arrows).</td></tr>
-  <tr><td>QCPItemRect</td><td>A rectangle</td></tr>
-  <tr><td>QCPItemEllipse</td><td>An ellipse</td></tr>
-  <tr><td>QCPItemPixmap</td><td>An arbitrary pixmap</td></tr>
-  <tr><td>QCPItemText</td><td>A text label</td></tr>
-  <tr><td>QCPItemBracket</td><td>A bracket which may be used to reference/highlight certain parts in the plot.</td></tr>
-  <tr><td>QCPItemTracer</td><td>An item that can be attached to a QCPGraph and sticks to its data points, given a key coordinate.</td></tr>
-  </table>
-  
-  \section items-clipping Clipping
-
-  Items are by default clipped to the main axis rect (they are only visible inside the axis rect).
-  To make an item visible outside that axis rect, disable clipping via \ref setClipToAxisRect
-  "setClipToAxisRect(false)".
-
-  On the other hand if you want the item to be clipped to a different axis rect, specify it via
-  \ref setClipAxisRect. This clipAxisRect property of an item is only used for clipping behaviour, and
-  in principle is independent of the coordinate axes the item might be tied to via its position
-  members (\ref QCPItemPosition::setAxes). However, it is common that the axis rect for clipping
-  also contains the axes used for the item positions.
-  
-  \section items-using Using items
-  
-  First you instantiate the item you want to use and add it to the plot:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-1
-  by default, the positions of the item are bound to the x- and y-Axis of the plot. So we can just
-  set the plot coordinates where the line should start/end:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-2
-  If we don't want the line to be positioned in plot coordinates but a different coordinate system,
-  e.g. absolute pixel positions on the QCustomPlot surface, we need to change the position type like this:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-3
-  Then we can set the coordinates, this time in pixels:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-4
-  and make the line visible on the entire QCustomPlot, by disabling clipping to the axis rect:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-5
-  
-  For more advanced plots, it is even possible to set different types and parent anchors per X/Y
-  coordinate of an item position, using for example \ref QCPItemPosition::setTypeX or \ref
-  QCPItemPosition::setParentAnchorX. For details, see the documentation of \ref QCPItemPosition.
-  
-  \section items-subclassing Creating own items
-  
-  To create an own item, you implement a subclass of QCPAbstractItem. These are the pure
-  virtual functions, you must implement:
-  \li \ref selectTest
-  \li \ref draw
-  
-  See the documentation of those functions for what they need to do.
-  
-  \subsection items-positioning Allowing the item to be positioned
-  
-  As mentioned, item positions are represented by QCPItemPosition members. Let's assume the new item shall
-  have only one point as its position (as opposed to two like a rect or multiple like a polygon). You then add
-  a public member of type QCPItemPosition like so:
-  
-  \code QCPItemPosition * const myPosition;\endcode
-  
-  the const makes sure the pointer itself can't be modified from the user of your new item (the QCPItemPosition
-  instance it points to, can be modified, of course).
-  The initialization of this pointer is made easy with the \ref createPosition function. Just assign
-  the return value of this function to each QCPItemPosition in the constructor of your item. \ref createPosition
-  takes a string which is the name of the position, typically this is identical to the variable name.
-  For example, the constructor of QCPItemExample could look like this:
-  
-  \code
-  QCPItemExample::QCPItemExample(QCustomPlot *parentPlot) :
-    QCPAbstractItem(parentPlot),
-    myPosition(createPosition("myPosition"))
-  {
-    // other constructor code
-  }
-  \endcode
-  
-  \subsection items-drawing The draw function
-  
-  To give your item a visual representation, reimplement the \ref draw function and use the passed
-  QCPPainter to draw the item. You can retrieve the item position in pixel coordinates from the
-  position member(s) via \ref QCPItemPosition::pixelPosition.
-
-  To optimize performance you should calculate a bounding rect first (don't forget to take the pen
-  width into account), check whether it intersects the \ref clipRect, and only draw the item at all
-  if this is the case.
-  
-  \subsection items-selection The selectTest function
-  
-  Your implementation of the \ref selectTest function may use the helpers \ref
-  QCPVector2D::distanceSquaredToLine and \ref rectDistance. With these, the implementation of the
-  selection test becomes significantly simpler for most items. See the documentation of \ref
-  selectTest for what the function parameters mean and what the function should return.
-  
-  \subsection anchors Providing anchors
-  
-  Providing anchors (QCPItemAnchor) starts off like adding a position. First you create a public
-  member, e.g.
-  
-  \code QCPItemAnchor * const bottom;\endcode
-
-  and create it in the constructor with the \ref createAnchor function, assigning it a name and an
-  anchor id (an integer enumerating all anchors on the item, you may create an own enum for this).
-  Since anchors can be placed anywhere, relative to the item's position(s), your item needs to
-  provide the position of every anchor with the reimplementation of the \ref anchorPixelPosition(int
-  anchorId) function.
-  
-  In essence the QCPItemAnchor is merely an intermediary that itself asks your item for the pixel
-  position when anything attached to the anchor needs to know the coordinates.

-  QCP::iSelectPlottables is set, the user may select plottables (graphs, curves, bars,...) and
-  their data by clicking on them or in their vicinity (\ref setSelectionTolerance). Whether the
-  user can actually select a plottable and its data can further be restricted with the \ref
-  QCPAbstractPlottable::setSelectable method on the specific plottable. For details, see the
-  special page about the \ref dataselection "data selection mechanism". To retrieve a list of all
-  currently selected plottables, call \ref selectedPlottables. If you're only interested in
-  QCPGraphs, you may use the convenience function \ref selectedGraphs.
-  
-  <b>Item selection</b> is controlled by \ref QCP::iSelectItems. If \ref QCP::iSelectItems is set, the user
-  may select items (QCPItemLine, QCPItemText,...) by clicking on them or in their vicinity. To find
-  out whether a specific item is selected, call QCPAbstractItem::selected(). To retrieve a list of
-  all currently selected items, call \ref selectedItems.
-  
-  <b>Axis selection</b> is controlled with \ref QCP::iSelectAxes. If \ref QCP::iSelectAxes is set, the user

-  \warning This is still an experimental feature and its performance depends on the system that it

-  might cause context conflicts on some systems.
-  
-  This method allows to enable OpenGL plot rendering, for increased plotting performance of
-  graphically demanding plots (thick lines, translucent fills, etc.).
-
-  If \a enabled is set to true, QCustomPlot will try to initialize OpenGL and, if successful,
-  continue plotting with hardware acceleration. The parameter \a multisampling controls how many
-  samples will be used per pixel, it essentially controls the antialiasing quality. If \a
-  multisampling is set too high for the current graphics hardware, the maximum allowed value will
-  be used.
-
-  You can test whether switching to OpenGL rendering was successful by checking whether the
-  according getter \a QCustomPlot::openGl() returns true. If the OpenGL initialization fails,
-  rendering continues with the regular software rasterizer, and an according qDebug output is
-  generated.
-
-  If switching to OpenGL was successful, this method disables label caching (\ref setPlottingHint
-  "setPlottingHint(QCP::phCacheLabels, false)") and turns on QCustomPlot's antialiasing override
-  for all elements (\ref setAntialiasedElements "setAntialiasedElements(QCP::aeAll)"), leading to a
-  higher quality output. The antialiasing override allows for pixel-grid aligned drawing in the
-  OpenGL paint device. As stated before, in OpenGL rendering the actual antialiasing of the plot is
-  controlled with \a multisampling. If \a enabled is set to false, the antialiasing/label caching
-  settings are restored to what they were before OpenGL was enabled, if they weren't altered in the
-  meantime.
-
-  \note OpenGL support is only enabled if QCustomPlot is compiled with the macro \c QCUSTOMPLOT_USE_OPENGL
-  defined. This define must be set before including the QCustomPlot header both during compilation
-  of the QCustomPlot library as well as when compiling your application. It is best to just include
-  the line <tt>DEFINES += QCUSTOMPLOT_USE_OPENGL</tt> in the respective qmake project files.
-  \note If you are using a Qt version before 5.0, you must also add the module "opengl" to your \c
-  QT variable in the qmake project files. For Qt versions 5.0 and higher, QCustomPlot switches to a
-  newer OpenGL interface which is already in the "gui" module.

-
-  The parameter \a refreshPriority can be used to fine-tune the timing of the replot. For example
-  if your application calls \ref replot very quickly in succession (e.g. multiple independent
-  functions change some aspects of the plot and each wants to make sure the change gets replotted),
-  it is advisable to set \a refreshPriority to \ref QCustomPlot::rpQueuedReplot. This way, the

-  replot with this priority will only cause a single replot, avoiding redundant replots and
-  improving performance.
-
-  Under a few circumstances, QCustomPlot causes a replot by itself. Those are resize events of the
-  QCustomPlot widget and user interactions (object selection and range dragging/zooming).
-
-  Before the replot happens, the signal \ref beforeReplot is emitted. After the replot, \ref
-  afterReplot is emitted. It is safe to mutually connect the replot slot with any of those two
-  signals on two QCustomPlots to make them replot synchronously, it won't cause an infinite
-  recursion.
-
-  If a layer is in mode \ref QCPLayer::lmBuffered (\ref QCPLayer::setMode), it is also possible to

-  Saves a PDF with the vectorized plot to the file \a fileName. The axis ratio as well as the scale
-  of texts and lines will be derived from the specified \a width and \a height. This means, the
-  output will look like the normal on-screen output of a QCustomPlot widget with the corresponding
-  pixel width and height. If either \a width or \a height is zero, the exported image will have the
-  same dimensions as the QCustomPlot widget currently has.
-
-  Setting \a exportPen to \ref QCP::epNoCosmetic allows to disable the use of cosmetic pens when
-  drawing to the PDF file. Cosmetic pens are pens with numerical width 0, which are always drawn as
-  a one pixel wide line, no matter what zoom factor is set in the PDF-Viewer. For more information
-  about cosmetic pens, see the QPainter and QPen documentation.
-
-  The objects of the plot will appear in the current selection state. If you don't want any
-  selected objects to be painted in their selected look, deselect everything with \ref deselectAll
-  before calling this function.
-
-  Returns true on success.
-
-  \warning
-  \li If you plan on editing the exported PDF file with a vector graphics editor like Inkscape, it
-  is advised to set \a exportPen to \ref QCP::epNoCosmetic to avoid losing those cosmetic lines
-  (which might be quite many, because cosmetic pens are the default for e.g. axes and tick marks).
-  \li If calling this function inside the constructor of the parent of the QCustomPlot widget
-  (i.e. the MainWindow constructor, if QCustomPlot is inside the MainWindow), always provide
-  explicit non-zero widths and heights. If you leave \a width or \a height as 0 (default), this
-  function uses the current width and height of the QCustomPlot widget. However, in Qt, these
-  aren't defined yet inside the constructor, so you would get an image that has strange
-  widths/heights.
-
-  \a pdfCreator and \a pdfTitle may be used to set the according metadata fields in the resulting
-  PDF file.
-
-  \note On Android systems, this method does nothing and issues an according qDebug warning
-  message. This is also the case if for other reasons the define flag \c QT_NO_PRINTER is set.

-
-  If you use a high scaling factor, it is recommended to enable antialiasing for all elements by

-/*! \class QCPColorGradient
-  \brief Defines a color gradient for use with e.g. \ref QCPColorMap
-  
-  This class describes a color gradient which can be used to encode data with color. For example,
-  QCPColorMap and QCPColorScale have \ref QCPColorMap::setGradient "setGradient" methods which
-  take an instance of this class. Colors are set with \ref setColorStopAt(double position, const QColor &color)
-  with a \a position from 0 to 1. In between these defined color positions, the
-  color will be interpolated linearly either in RGB or HSV space, see \ref setColorInterpolation.
-
-  Alternatively, load one of the preset color gradients shown in the image below, with \ref
-  loadPreset, or by directly specifying the preset in the constructor.
-  
-  Apart from red, green and blue components, the gradient also interpolates the alpha values of the
-  configured color stops. This allows to display some portions of the data range as transparent in
-  the plot.
-  
-  \image html QCPColorGradient.png
-  
-  The \ref QCPColorGradient(GradientPreset preset) constructor allows directly converting a \ref
-  GradientPreset to a QCPColorGradient. This means that you can directly pass \ref GradientPreset
-  to all the \a setGradient methods, e.g.:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorgradient-setgradient
-  
-  The total number of levels used in the gradient can be set with \ref setLevelCount. Whether the
-  color gradient shall be applied periodically (wrapping around) to data values that lie outside
-  the data range specified on the plottable instance can be controlled with \ref setPeriodic.

-/*! \class QCPAxisRect
-  \brief Holds multiple axes and arranges them in a rectangular shape.
-  
-  This class represents an axis rect, a rectangular area that is bounded on all sides with an
-  arbitrary number of axes.
-  
-  Initially QCustomPlot has one axis rect, accessible via QCustomPlot::axisRect(). However, the
-  layout system allows to have multiple axis rects, e.g. arranged in a grid layout
-  (QCustomPlot::plotLayout).
-  
-  By default, QCPAxisRect comes with four axes, at bottom, top, left and right. They can be
-  accessed via \ref axis by providing the respective axis type (\ref QCPAxis::AxisType) and index.
-  If you need all axes in the axis rect, use \ref axes. The top and right axes are set to be
-  invisible initially (QCPAxis::setVisible). To add more axes to a side, use \ref addAxis or \ref
-  addAxes. To remove an axis, use \ref removeAxis.
-  
-  The axis rect layerable itself only draws a background pixmap or color, if specified (\ref
-  setBackground). It is placed on the "background" layer initially (see \ref QCPLayer for an
-  explanation of the QCustomPlot layer system). The axes that are held by the axis rect can be
-  placed on other layers, independently of the axis rect.
-  
-  Every axis rect has a child layout of type \ref QCPLayoutInset. It is accessible via \ref
-  insetLayout and can be used to have other layout elements (or even other layouts with multiple
-  elements) hovering inside the axis rect.
-  
-  If an axis rect is clicked and dragged, it processes this by moving certain axis ranges. The
-  behaviour can be controlled with \ref setRangeDrag and \ref setRangeDragAxes. If the mouse wheel
-  is scrolled while the cursor is on the axis rect, certain axes are scaled. This is controllable
-  via \ref setRangeZoom, \ref setRangeZoomAxes and \ref setRangeZoomFactor. These interactions are
-  only enabled if \ref QCustomPlot::setInteractions contains \ref QCP::iRangeDrag and \ref
-  QCP::iRangeZoom.

-  \brief A legend item representing a plottable with an icon and the plottable name.
-  
-  This is the standard legend item for plottables. It displays an icon of the plottable next to the

-  QCPAbstractPlottable::drawLegendIcon), and tries to give an intuitive symbol for the plottable.
-  For example, the QCPGraph draws a centered horizontal line and/or a single scatter point in the
-  middle.
-  
-  Legend items of this type are always associated with one plottable (retrievable via the
-  plottable() function and settable with the constructor). You may change the font of the plottable
-  name with \ref setFont. Icon padding and border pen is taken from the parent QCPLegend, see \ref
-  QCPLegend::setIconBorderPen and \ref QCPLegend::setIconTextPadding.
-
-  The function \ref QCPAbstractPlottable::addToLegend/\ref QCPAbstractPlottable::removeFromLegend

-  Since QCPLegend is based on QCPLayoutGrid, a legend item itself is just a subclass of

-/*! \class QCPLegend
-  \brief Manages a legend inside a QCustomPlot.
-
-  A legend is a small box somewhere in the plot which lists plottables with their name and icon.
-
-  A legend is populated with legend items by calling \ref QCPAbstractPlottable::addToLegend on the
-  plottable, for which a legend item shall be created. In the case of the main legend (\ref
-  QCustomPlot::legend), simply adding plottables to the plot while \ref
-  QCustomPlot::setAutoAddPlottableToLegend is set to true (the default) creates corresponding
-  legend items. The legend item associated with a certain plottable can be removed with \ref
-  QCPAbstractPlottable::removeFromLegend. However, QCPLegend also offers an interface to add and
-  manipulate legend items directly: \ref item, \ref itemWithPlottable, \ref itemCount, \ref
-  addItem, \ref removeItem, etc.
-
-  Since \ref QCPLegend derives from \ref QCPLayoutGrid, it can be placed in any position a \ref
-  QCPLayoutElement may be positioned. The legend items are themselves \ref QCPLayoutElement
-  "QCPLayoutElements" which are placed in the grid layout of the legend. \ref QCPLegend only adds
-  an interface specialized for handling child elements of type \ref QCPAbstractLegendItem, as
-  mentioned above. In principle, any other layout elements may also be added to a legend via the
-  normal \ref QCPLayoutGrid interface. See the special page about \link thelayoutsystem The Layout
-  System\endlink for examples on how to add other elements to the legend and move it outside the axis
-  rect.
-
-  Use the methods \ref setFillOrder and \ref setWrap inherited from \ref QCPLayoutGrid to control
-  in which order (column first or row first) the legend is filled up when calling \ref addItem, and
-  at which column or row wrapping occurs.
-
-  By default, every QCustomPlot has one legend (\ref QCustomPlot::legend) which is placed in the
-  inset layout of the main axis rect (\ref QCPAxisRect::insetLayout). To move the legend to another
-  position inside the axis rect, use the methods of the \ref QCPLayoutInset. To move the legend
-  outside of the axis rect, place it anywhere else with the \ref QCPLayout/\ref QCPLayoutElement
-  interface.

-  is usually used in combination with one or multiple \ref QCPColorMap "QCPColorMaps".
-
-  \image html QCPColorScale.png
-  
-  The color scale can be either horizontal or vertical, as shown in the image above. The
-  orientation and the side where the numbers appear is controlled with \ref setType.
-  
-  Use \ref QCPColorMap::setColorScale to connect a color map with a color scale. Once they are
-  connected, they share their gradient, data range and data scale type (\ref setGradient, \ref
-  setDataRange, \ref setDataScaleType). Multiple color maps may be associated with a single color
-  scale, to make them all synchronize these properties.
-  
-  To have finer control over the number display and axis behaviour, you can directly access the
-  \ref axis. See the documentation of QCPAxis for details about configuring axes. For example, if
-  you want to change the number of automatically generated ticks, call
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorscale-tickcount
-  
-  Placing a color scale next to the main axis rect works like with any other layout element:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorscale-creation
-  In this case we have placed it to the right of the default axis rect, so it wasn't necessary to
-  call \ref setType, since \ref QCPAxis::atRight is already the default. The text next to the color
-  scale can be set with \ref setLabel.
-  
-  For optimum appearance (like in the image above), it may be desirable to line up the axis rect and
-  the borders of the color scale. Use a \ref QCPMarginGroup to achieve this:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorscale-margingroup
-  
-  Color scales are initialized with a non-zero minimum top and bottom margin (\ref
-  setMinimumMargins), because vertical color scales are most common and the minimum top/bottom
-  margin makes sure it keeps some distance to the top/bottom widget border. So if you change to a
-  horizontal color scale by setting \ref setType to \ref QCPAxis::atBottom or \ref QCPAxis::atTop, you
-  might want to also change the minimum margins accordingly, e.g. <tt>setMinimumMargins(QMargins(6, 0, 6, 0))</tt>.

-/*! \fn QCPAxis *QCPColorScale::axis() const

-  Returns the internal \ref QCPAxis instance of this color scale. You can access it to alter the
-  appearance and behaviour of the axis. \ref QCPColorScale duplicates some properties in its
-  interface for convenience. Those are \ref setDataRange (\ref QCPAxis::setRange), \ref
-  setDataScaleType (\ref QCPAxis::setScaleType), and the method \ref setLabel (\ref

-  the QCPColorScale or on its QCPAxis.
-  
-  If the type of the color scale is changed with \ref setType, the axis returned by this method
-  will change, too, to either the left, right, bottom or top axis, depending on which type was set.

-/*! \class QCPGraph
-  \brief A plottable representing a graph in a plot.
-
-  \image html QCPGraph.png
-  
-  Usually you create new graphs by calling QCustomPlot::addGraph. The resulting instance can be
-  accessed via QCustomPlot::graph.
-
-  To plot data, assign it with the \ref setData or \ref addData functions. Alternatively, you can
-  also access and modify the data via the \ref data method, which returns a pointer to the internal
-  \ref QCPGraphDataContainer.
-  
-  Graphs are used to display single-valued data. Single-valued means that there should only be one
-  data point per unique key coordinate. In other words, the graph can't have \a loops. If you do
-  want to plot non-single-valued curves, rather use the QCPCurve plottable.
-  
-  Gaps in the graph line can be created by adding data points with NaN as value
-  (<tt>qQNaN()</tt> or <tt>std::numeric_limits<double>::quiet_NaN()</tt>) in between the two data points that shall be
-  separated.
-  
-  \section qcpgraph-appearance Changing the appearance
-  
-  The appearance of the graph is mainly determined by the line style, scatter style, brush and pen
-  of the graph (\ref setLineStyle, \ref setScatterStyle, \ref setBrush, \ref setPen).
-  
-  \subsection filling Filling under or between graphs
-  
-  QCPGraph knows two types of fills: Normal graph fills towards the zero-value-line parallel to
-  the key axis of the graph, and fills between two graphs, called channel fills. To enable a fill,
-  just set a brush with \ref setBrush which is neither Qt::NoBrush nor fully transparent.
-  
-  By default, a normal fill towards the zero-value-line will be drawn. To set up a channel fill
-  between this graph and another one, call \ref setChannelFillGraph with the other graph as
-  parameter.

-  sampling technique can drastically improve the replot performance for graphs with a larger number
-  of points (e.g. above 10,000), without notably changing the appearance of the graph.
-  
-  By default, adaptive sampling is enabled. Even if enabled, QCustomPlot decides whether adaptive
-  sampling shall actually be used on a per-graph basis. So leaving adaptive sampling enabled has no
-  disadvantage in almost all cases.
-  
-  \image html adaptive-sampling-line.png "A line plot of 500,000 points without and with adaptive sampling"
-  
-  As can be seen, line plots experience no visual degradation from adaptive sampling. Outliers are
-  reproduced reliably, as well as the overall shape of the data set. The replot time reduces
-  dramatically though. This allows QCustomPlot to display large amounts of data in realtime.
-  
-  \image html adaptive-sampling-scatter.png "A scatter plot of 100,000 points without and with adaptive sampling"
-  
-  Care must be taken when using high-density scatter plots in combination with adaptive sampling.
-  The adaptive sampling algorithm treats scatter plots more carefully than line plots which still
-  gives a significant reduction of replot times, but not quite as much as for line plots. This is
-  because scatter plots inherently need more data points to be preserved in order to still resemble
-  the original, non-adaptive-sampling plot. As shown above, the results still aren't quite
-  identical, as banding occurs for the outer data points. This is in fact intentional, such that
-  the boundaries of the data cloud stay visible to the viewer. How strong the banding appears,
-  depends on the point density, i.e. the number of points in the plot.
-  
-  For some situations with scatter plots it might thus be desirable to manually turn adaptive
-  sampling off. For example, when saving the plot to disk. This can be achieved by setting \a
-  enabled to false before issuing a command like \ref QCustomPlot::savePng, and setting \a enabled
-  back to true afterwards.

-/*! \class QCPCurve
-  \brief A plottable representing a parametric curve in a plot.
-  
-  \image html QCPCurve.png
-  
-  Unlike QCPGraph, plottables of this type may have multiple points with the same key coordinate,
-  so their visual representation can have \a loops. This is realized by introducing a third
-  coordinate \a t, which defines the order of the points described by the other two coordinates \a
-  x and \a y.
-
-  To plot data, assign it with the \ref setData or \ref addData functions. Alternatively, you can
-  also access and modify the curve's data via the \ref data method, which returns a pointer to the
-  internal \ref QCPCurveDataContainer.
-  
-  Gaps in the curve can be created by adding data points with NaN as key and value
-  (<tt>qQNaN()</tt> or <tt>std::numeric_limits<double>::quiet_NaN()</tt>) in between the two data points that shall be
-  separated.
-  
-  \section qcpcurve-appearance Changing the appearance
-  
-  The appearance of the curve is determined by the pen and the brush (\ref setPen, \ref setBrush).
-  
-  \section qcpcurve-usage Usage
-  
-  Like all data representing objects in QCustomPlot, the QCPCurve is a plottable
-  (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
-  (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
-  
-  Usually, you first create an instance:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcurve-creation-1
-  which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot instance takes
-  ownership of the plottable, so do not delete it manually but use QCustomPlot::removePlottable() instead.
-  The newly created plottable can be modified, e.g.:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcurve-creation-2

-  regular \ref setData or \ref addData methods.

-  Constructs a curve which uses \a keyAxis as its key axis ("x") and \a valueAxis as its value

-  printed to the debug output (qDebug), the construction is not aborted, though.
-  
-  The created QCPCurve is automatically registered with the QCustomPlot instance inferred from \a
-  keyAxis. This QCustomPlot instance takes ownership of the QCPCurve, so do not delete it manually

-  This function is part of the curve optimization algorithm of \ref getCurveLines.
-  
-  In situations where a single segment skips over multiple regions it might become necessary to add
-  extra points at the corners of region 5 (see \ref getRegion) such that the optimized segment
-  doesn't unintentionally cut through the visible area of the axis rect and create plot artifacts.
-  This method provides these points that must be added, assuming the original segment doesn't
-  start, end, or traverse region 5. (Corner points where region 5 is traversed are calculated by
-  \ref getTraverseCornerPoints.)
-  
-  For example, consider a segment which directly goes from region 4 to 2 but originally is far out
-  to the top left such that it doesn't cross region 5. Naively optimizing these points by
-  projecting them on the top and left borders of region 5 will create a segment that surely crosses
-  5, creating a visual artifact in the plot. This method prevents this by providing extra points at
-  the top left corner, making the optimized curve correctly pass from region 4 to 1 to 2 without
-  traversing 5.

-  As an example, consider a segment going from region 1 to region 6, traversing the lower left

-  the top left corner, before adding the optimized traverse points. So in this case, the output
-  parameter \a beforeTraverse will contain the top left corner point, and \a afterTraverse will be
-  empty.
-  
-  In some cases, such as when going from region 1 to 9, it may even be necessary to add additional
-  corner points before and after the traverse. Then both \a beforeTraverse and \a afterTraverse
-  return the respective corner points.

-/*! \class QCPBarsGroup
-  \brief Groups multiple QCPBars together so they appear side by side
-  
-  \image html QCPBarsGroup.png
-  
-  When showing multiple QCPBars in one plot which have bars at identical keys, it may be desirable
-  to have them appearing next to each other at each key. This is what adding the respective QCPBars
-  plottables to a QCPBarsGroup achieves. (An alternative approach is to stack them on top of each
-  other, see \ref QCPBars::moveAbove.)
-  
-  \section qcpbarsgroup-usage Usage
-  
-  To add a QCPBars plottable to the group, create a new group and then add the respective bars
-  intances:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpbarsgroup-creation
-  Alternatively to appending to the group like shown above, you can also set the group on the
-  QCPBars plottable via \ref QCPBars::setBarsGroup.
-  
-  The spacing between the bars can be configured via \ref setSpacingType and \ref setSpacing. The
-  bars in this group appear in the plot in the order they were appended. To insert a bars plottable
-  at a certain index position, or to reposition a bars plottable which is already in the group, use
-  \ref insert.
-  
-  To remove specific bars from the group, use either \ref remove or call \ref
-  QCPBars::setBarsGroup "QCPBars::setBarsGroup(0)" on the respective bars plottable.
-  
-  To clear the entire group, call \ref clear, or simply delete the group.

-  
-  \section qcpbars-appearance Changing the appearance

-  The width of the individual bars can be controlled with \ref setWidthType and \ref setWidth.
-  
-  Bar charts are stackable. This means, two QCPBars plottables can be placed on top of each other

-/*! \class QCPStatisticalBox
-  \brief A plottable representing a single statistical box in a plot.
-
-  \image html QCPStatisticalBox.png
-  
-  To plot data, assign it with the \ref setData or \ref addData functions. Alternatively, you can
-  also access and modify the data via the \ref data method, which returns a pointer to the internal
-  \ref QCPStatisticalBoxDataContainer.
-  
-  Additionally each data point can itself have a list of outliers, drawn as scatter points at the
-  key coordinate of the respective statistical box data point. They can either be set by using the
-  respective \ref addData(double,double,double,double,double,double,const QVector<double>&)
-  "addData" method or accessing the individual data points through \ref data, and setting the
-  <tt>QVector<double> outliers</tt> of the data points directly.
-  
-  \section qcpstatisticalbox-appearance Changing the appearance
-  
-  The appearance of each data point box, ranging from the lower to the upper quartile, is
-  controlled via \ref setPen and \ref setBrush. You may change the width of the boxes with \ref
-  setWidth in plot coordinates.
-
-  Each data point's visual representation also consists of two whiskers. Whiskers are the lines
-  which reach from the upper quartile to the maximum, and from the lower quartile to the minimum.
-  The appearance of the whiskers can be modified with: \ref setWhiskerPen, \ref setWhiskerBarPen,
-  \ref setWhiskerWidth. The whisker width is the width of the bar perpendicular to the whisker at
-  the top (for maximum) and bottom (for minimum). If the whisker pen is changed, make sure to set
-  the \c capStyle to \c Qt::FlatCap. Otherwise the backbone line might exceed the whisker bars by a
-  few pixels due to the pen cap being not perfectly flat.
-  
-  The median indicator line inside the box has its own pen, \ref setMedianPen.
-  
-  The outlier data points are drawn as normal scatter points. Their look can be controlled with
-  \ref setOutlierStyle
-  
-  \section qcpstatisticalbox-usage Usage
-  
-  Like all data representing objects in QCustomPlot, the QCPStatisticalBox is a plottable
-  (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
-  (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
-  
-  Usually, you first create an instance:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpstatisticalbox-creation-1
-  which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot instance takes
-  ownership of the plottable, so do not delete it manually but use QCustomPlot::removePlottable() instead.
-  The newly created plottable can be modified, e.g.:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpstatisticalbox-creation-2

-/*! \fn QSharedPointer<QCPStatisticalBoxDataContainer> QCPStatisticalBox::data() const
-  
-  Returns a shared pointer to the internal data storage of type \ref
-  QCPStatisticalBoxDataContainer. You may use it to directly manipulate the data, which may be more
-  convenient and faster than using the regular \ref setData or \ref addData methods.

-  message is printed to the debug output (qDebug), the construction is not aborted, though.

-/*! \class QCPColorMapData
-  \brief Holds the two-dimensional data of a QCPColorMap plottable.
-  
-  This class is a data storage for \ref QCPColorMap. It holds a two-dimensional array, which \ref
-  QCPColorMap then displays as a 2D image in the plot, where the array values are represented by a
-  color, depending on the value.
-  
-  The size of the array can be controlled via \ref setSize (or \ref setKeySize, \ref setValueSize).
-  Which plot coordinates these cells correspond to can be configured with \ref setRange (or \ref
-  setKeyRange, \ref setValueRange).
-  
-  The data cells can be accessed in two ways: They can be directly addressed by an integer index
-  with \ref setCell. This is the fastest method. Alternatively, they can be addressed by their plot
-  coordinate with \ref setData. plot coordinate to cell index transformations and vice versa are
-  provided by the functions \ref coordToCell and \ref cellToCoord.
-  
-  A \ref QCPColorMapData also holds an on-demand two-dimensional array of alpha values which (if
-  allocated) has the same size as the data map. It can be accessed via \ref setAlpha, \ref
-  fillAlpha and \ref clearAlpha. The memory for the alpha map is only allocated if needed, i.e. on
-  the first call of \ref setAlpha. \ref clearAlpha restores full opacity and frees the alpha map.
-  
-  This class also buffers the minimum and maximum values that are in the data set, to provide
-  QCPColorMap::rescaleDataRange with the necessary information quickly. Setting a cell to a value
-  that is greater than the current maximum increases this maximum to the new value. However,
-  setting the cell that currently holds the maximum value to a smaller value doesn't decrease the
-  maximum again, because finding the true new maximum would require going through the entire data
-  array, which might be time consuming. The same holds for the data minimum. This functionality is
-  given by \ref recalculateDataBounds, such that you can decide when it is sensible to find the
-  true current minimum and maximum. The method QCPColorMap::rescaleDataRange offers a convenience
-  parameter \a recalculateDataBounds which may be set to true to automatically call \ref
-  recalculateDataBounds internally.

-/*! \class QCPColorMap
-  \brief A plottable representing a two-dimensional color map in a plot.
-
-  \image html QCPColorMap.png
-  
-  The data is stored in the class \ref QCPColorMapData, which can be accessed via the data()
-  method.
-  
-  A color map has three dimensions to represent a data point: The \a key dimension, the \a value
-  dimension and the \a data dimension. As with other plottables such as graphs, \a key and \a value
-  correspond to two orthogonal axes on the QCustomPlot surface that you specify in the QCPColorMap
-  constructor. The \a data dimension however is encoded as the color of the point at (\a key, \a
-  value).
-
-  Set the number of points (or \a cells) in the key/value dimension via \ref
-  QCPColorMapData::setSize. The plot coordinate range over which these points will be displayed is
-  specified via \ref QCPColorMapData::setRange. The first cell will be centered on the lower range
-  boundary and the last cell will be centered on the upper range boundary. The data can be set by
-  either accessing the cells directly with QCPColorMapData::setCell or by addressing the cells via
-  their plot coordinates with \ref QCPColorMapData::setData. If possible, you should prefer
-  setCell, since it doesn't need to do any coordinate transformation and thus performs a bit
-  better.
-  
-  The cell with index (0, 0) is at the bottom left, if the color map uses normal (i.e. not reversed)
-  key and value axes.
-  
-  To show the user which colors correspond to which \a data values, a \ref QCPColorScale is
-  typically placed to the right of the axis rect. See the documentation there for details on how to
-  add and use a color scale.
-  
-  \section qcpcolormap-appearance Changing the appearance
-  
-  The central part of the appearance is the color gradient, which can be specified via \ref
-  setGradient. See the documentation of \ref QCPColorGradient for details on configuring a color
-  gradient.
-  
-  The \a data range that is mapped to the colors of the gradient can be specified with \ref
-  setDataRange. To make the data range encompass the whole data set minimum to maximum, call \ref
-  rescaleDataRange.
-  
-  \section qcpcolormap-transparency Transparency
-  
-  Transparency in color maps can be achieved by two mechanisms. On one hand, you can specify alpha
-  values for color stops of the \ref QCPColorGradient, via the regular QColor interface. This will
-  cause the color map data which gets mapped to colors around those color stops to appear with the
-  accordingly interpolated transparency.
-  
-  On the other hand you can also directly apply an alpha value to each cell independent of its
-  data, by using the alpha map feature of \ref QCPColorMapData. The relevant methods are \ref
-  QCPColorMapData::setAlpha, QCPColorMapData::fillAlpha and \ref QCPColorMapData::clearAlpha().
-  
-  The two transparencies will be joined together in the plot and otherwise not interfere with each
-  other. They are mixed in a multiplicative matter, so an alpha of e.g. 50% (128/255) in both modes
-  simultaneously, will result in a total transparency of 25% (64/255).
-  
-  \section qcpcolormap-usage Usage
-  
-  Like all data representing objects in QCustomPlot, the QCPColorMap is a plottable
-  (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
-  (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
-  
-  Usually, you first create an instance:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolormap-creation-1
-  which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot instance takes
-  ownership of the plottable, so do not delete it manually but use QCustomPlot::removePlottable() instead.
-  The newly created plottable can be modified, e.g.:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolormap-creation-2
-  
-  \note The QCPColorMap always displays the data at equal key/value intervals, even if the key or
-  value axis is set to a logarithmic scaling. If you want to use QCPColorMap with logarithmic axes,
-  you shouldn't use the \ref QCPColorMapData::setData method as it uses a linear transformation to
-  determine the cell index. Rather directly access the cell index with \ref
-  QCPColorMapData::setCell.

-/*! \class QCPFinancial
-  \brief A plottable representing a financial stock chart
-
-  \image html QCPFinancial.png
-
-  This plottable represents time series data binned to certain intervals, mainly used for stock
-  charts. The two common representations OHLC (Open-High-Low-Close) bars and Candlesticks can be
-  set via \ref setChartStyle.
-
-  The data is passed via \ref setData as a set of open/high/low/close values at certain keys
-  (typically times). This means the data must be already binned appropriately. If data is only
-  available as a series of values (e.g. \a price against \a time), you can use the static
-  convenience function \ref timeSeriesToOhlc to generate binned OHLC-data which can then be passed
-  to \ref setData.
-
-  The width of the OHLC bars/candlesticks can be controlled with \ref setWidth and \ref
-  setWidthType. A typical choice is to set the width type to \ref wtPlotCoords (the default) and
-  the width to (or slightly less than) one time bin interval width.
-
-  \section qcpfinancial-appearance Changing the appearance
-
-  Charts can be either single- or two-colored (\ref setTwoColored). If set to be single-colored,
-  lines are drawn with the plottable's pen (\ref setPen) and fills with the brush (\ref setBrush).
-
-  If set to two-colored, positive changes of the value during an interval (\a close >= \a open) are
-  represented with a different pen and brush than negative changes (\a close < \a open). These can
-  be configured with \ref setPenPositive, \ref setPenNegative, \ref setBrushPositive, and \ref
-  setBrushNegative. In two-colored mode, the normal plottable pen/brush is ignored. Upon selection
-  however, the normal selected pen/brush (provided by the \ref selectionDecorator) is used,
-  irrespective of whether the chart is single- or two-colored.
-
-  \section qcpfinancial-usage Usage
-
-  Like all data representing objects in QCustomPlot, the QCPFinancial is a plottable
-  (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
-  (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
-
-  Usually, you first create an instance:
-
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpfinancial-creation-1
-  which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot
-  instance takes ownership of the plottable, so do not delete it manually but use
-  QCustomPlot::removePlottable() instead. The newly created plottable can be modified, e.g.:
-
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpfinancial-creation-2
-  Here we have used the static helper method \ref timeSeriesToOhlc, to turn a time-price data
-  series into a 24-hour binned open-high-low-close data series as QCPFinancial uses.

-  Returns a pointer to the internal data storage of type \ref QCPFinancialDataContainer. You may

-  regular \ref setData or \ref addData methods, in certain situations.

-  printed to the debug output (qDebug), the construction is not aborted, though.

-  \brief A plottable that adds a set of error bars to other plottables.
-
-  \image html QCPErrorBars.png
-
-  The \ref QCPErrorBars plottable can be attached to other one-dimensional plottables (e.g. \ref
-  QCPGraph, \ref QCPCurve, \ref QCPBars, etc.) and equips them with error bars.
-
-  Use \ref setDataPlottable to define for which plottable the \ref QCPErrorBars shall display the
-  error bars. The orientation of the error bars can be controlled with \ref setErrorType.
-
-  By using \ref setData, you can supply the actual error data, either as symmetric error or
-  plus/minus asymmetric errors. \ref QCPErrorBars only stores the error data. The absolute
-  key/value position of each error bar will be adopted from the configured data plottable. The
-  error data of the \ref QCPErrorBars are associated one-to-one via their index to the data points
-  of the data plottable. You can directly access and manipulate the error bar data via \ref data.
-
-  Set either of the plus/minus errors to NaN (<tt>qQNaN()</tt> or
-  <tt>std::numeric_limits<double>::quiet_NaN()</tt>) to not show the respective error bar on the data point at
-  that index.
-
-  \section qcperrorbars-appearance Changing the appearance
-
-  The appearance of the error bars is defined by the pen (\ref setPen), and the width of the
-  whiskers (\ref setWhiskerWidth). Further, the error bar backbones may leave a gap around the data
-  point center to prevent that error bars are drawn too close to or even through scatter points.
-  This gap size can be controlled via \ref setSymbolGap.

-/*! \class QCPItemTracer
-  \brief Item that sticks to QCPGraph data points
-
-  \image html QCPItemTracer.png "Tracer example. Blue dotted circles are anchors, solid blue discs are positions."
-
-  The tracer can be connected with a QCPGraph via \ref setGraph. Then it will automatically adopt
-  the coordinate axes of the graph and update its \a position to be on the graph's data. This means
-  the key stays controllable via \ref setGraphKey, but the value will follow the graph data. If a
-  QCPGraph is connected, note that setting the coordinates of the tracer item directly via \a
-  position will have no effect because they will be overriden in the next redraw (this is when the
-  coordinate update happens).
-  
-  If the specified key in \ref setGraphKey is outside the key bounds of the graph, the tracer will
-  stay at the corresponding end of the graph.
-  
-  With \ref setInterpolating you may specify whether the tracer may only stay exactly on data
-  points or whether it interpolates data points linearly, if given a key that lies between two data
-  points of the graph.
-  
-  The tracer has different visual styles, see \ref setStyle. It is also possible to make the tracer
-  have no own visual appearance (set the style to \ref tsNone), and just connect other item
-  positions to the tracer \a position (used as an anchor) via \ref
-  QCPItemPosition::setParentAnchor.
-  
-  \note The tracer position is only automatically updated upon redraws. So when the data of the
-  graph changes and immediately afterwards (without a redraw) the position coordinates of the
-  tracer are retrieved, they will not reflect the updated data of the graph. In this case \ref
-  updatePosition must be called manually, prior to reading the tracer coordinates.

-/*! \class QCPDataContainer
-  \brief The generic data container for one-dimensional plottables
-
-  This class template provides a fast container for data storage of one-dimensional data. The data
-  type is specified as template parameter (called \a DataType in the following) and must provide
-  some methods as described in the \ref qcpdatacontainer-datatype "next section".
-
-  The data is stored in a sorted fashion, which allows very quick lookups by the sorted key as well
-  as retrieval of ranges (see \ref findBegin, \ref findEnd, \ref keyRange) using binary search. The
-  container uses a preallocation and a postallocation scheme, such that appending and prepending
-  data (with respect to the sort key) is very fast and minimizes reallocations. If data is added
-  which needs to be inserted between existing keys, the merge usually can be done quickly too,
-  using the fact that existing data is always sorted. The user can further improve performance by
-  specifying that added data is already itself sorted by key, if he can guarantee that this is the
-  case (see for example \ref add(const QVector<DataType> &data, bool alreadySorted)).
-
-  The data can be accessed with the provided const iterators (\ref constBegin, \ref constEnd). If
-  it is necessary to alter existing data in-place, the non-const iterators can be used (\ref begin,
-  \ref end). Changing data members that are not the sort key (for most data types called \a key) is
-  safe from the container's perspective.
-
-  Great care must be taken however if the sort key is modified through the non-const iterators. For
-  performance reasons, the iterators don't automatically cause a re-sorting upon their
-  manipulation. It is thus the responsibility of the user to leave the container in a sorted state
-  when finished with the data manipulation, before calling any other methods on the container. A
-  complete re-sort (e.g. after finishing all sort key manipulation) can be done by calling \ref
-  sort. Failing to do so can not be detected by the container efficiently and will cause both
-  rendering artifacts and potential data loss.
-
-  Implementing one-dimensional plottables that make use of a \ref QCPDataContainer<T> is usually
-  done by subclassing from \ref QCPAbstractPlottable1D "QCPAbstractPlottable1D<T>", which
-  introduces an according \a mDataContainer member and some convenience methods.
-
-  \section qcpdatacontainer-datatype Requirements for the DataType template parameter
-
-  The template parameter <tt>DataType</tt> is the type of the stored data points. It must be
-  trivially copyable and have the following public methods, preferably inline:
-
-  \li <tt>double sortKey() const</tt>\n Returns the member variable of this data point that is the
-  sort key, defining the ordering in the container. Often this variable is simply called \a key.
-
-  \li <tt>static DataType fromSortKey(double sortKey)</tt>\n Returns a new instance of the data
-  type initialized with its sort key set to \a sortKey.
-
-  \li <tt>static bool sortKeyIsMainKey()</tt>\n Returns true if the sort key is equal to the main
-  key (see method \c mainKey below). For most plottables this is the case. It is not the case for
-  example for \ref QCPCurve, which uses \a t as sort key and \a key as main key. This is the reason
-  why QCPCurve unlike QCPGraph can display parametric curves with loops.
-
-  \li <tt>double mainKey() const</tt>\n Returns the variable of this data point considered the main
-  key. This is commonly the variable that is used as the coordinate of this data point on the key
-  axis of the plottable. This method is used for example when determining the automatic axis
-  rescaling of key axes (\ref QCPAxis::rescale).
-
-  \li <tt>double mainValue() const</tt>\n Returns the variable of this data point considered the
-  main value. This is commonly the variable that is used as the coordinate of this data point on
-  the value axis of the plottable.
-
-  \li <tt>QCPRange valueRange() const</tt>\n Returns the range this data point spans in the value
-  axis coordinate. If the data is single-valued (e.g. QCPGraphData), this is simply a range with
-  both lower and upper set to the main data point value. However if the data points can represent
-  multiple values at once (e.g QCPFinancialData with its \a high, \a low, \a open and \a close
-  values at each \a key) this method should return the range those values span. This method is used
-  for example when determining the automatic axis rescaling of value axes (\ref
-  QCPAxis::rescale).

-/*! \class QCPPlottableInterface1D
-  \brief Defines an abstract interface for one-dimensional plottables
-
-  This class contains only pure virtual methods which define a common interface to the data
-  of one-dimensional plottables.
-
-  For example, it is implemented by the template class \ref QCPAbstractPlottable1D (the preferred
-  base class for one-dimensional plottables). So if you use that template class as base class of
-  your one-dimensional plottable, you won't have to care about implementing the 1d interface
-  yourself.
-
-  If your plottable doesn't derive from \ref QCPAbstractPlottable1D but still wants to provide a 1d
-  interface (e.g. like \ref QCPErrorBars does), you should inherit from both \ref
-  QCPAbstractPlottable and \ref QCPPlottableInterface1D and accordingly reimplement the pure
-  virtual methods of the 1d interface, matching your data container. Also, reimplement \ref
-  QCPAbstractPlottable::interface1D to return the \c this pointer.
-
-  If you have a \ref QCPAbstractPlottable pointer, you can check whether it implements this
-  interface by calling \ref QCPAbstractPlottable::interface1D and testing it for a non-zero return
-  value. If it indeed implements this interface, you may use it to access the plottable's data
-  without needing to know the exact type of the plottable or its data point type.

-  
-  If \a onlySelectable is true, an empty QCPDataSelection is returned if this plottable is not
-  selectable (i.e. if \ref QCPAbstractPlottable::setSelectable is \ref QCP::stNone).
-  
-  \note \a rect must be a normalized rect (positive or zero width and height). This is especially

-/*! \class QCPAbstractPlottable1D
-  \brief A template base class for plottables with one-dimensional data
-
-  This template class derives from \ref QCPAbstractPlottable and from the abstract interface \ref
-  QCPPlottableInterface1D. It serves as a base class for all one-dimensional data (i.e. data with
-  one key dimension), such as \ref QCPGraph and QCPCurve.
-
-  The template parameter \a DataType is the type of the data points of this plottable (e.g. \ref
-  QCPGraphData or \ref QCPCurveData). The main purpose of this base class is to provide the member
-  \a mDataContainer (a shared pointer to a \ref QCPDataContainer "QCPDataContainer<DataType>") and
-  implement the according virtual methods of the \ref QCPPlottableInterface1D, such that most
-  subclassed plottables don't need to worry about this anymore.
-
-  Further, it provides a convenience method for retrieving selected/unselected data segments via
-  \ref getDataSegments. This is useful when subclasses implement their \ref draw method and need to
-  draw selected segments with a different pen/brush than unselected segments (also see \ref
-  QCPSelectionDecorator).
-
-  This class implements basic functionality of \ref QCPAbstractPlottable::selectTest and \ref
-  QCPPlottableInterface1D::selectTestRect, assuming point-like data points, based on the 1D data
-  interface. In spite of that, most plottable subclasses will want to reimplement those methods
-  again, to provide a more accurate hit test based on their specific data visualization geometry.

+

+
+  A paint buffer manages both a surface to draw onto, and the matching paint device. The size of
+  the surface can be changed via \ref setSize. External classes (\ref QCustomPlot and \ref
+  QCPLayer) request a painter via \ref startPainting and then perform the draw calls. Once the
+  painting is complete, \ref donePainting is called, so the paint buffer implementation can do
+  clean up if necessary. Before rendering a frame, each paint buffer is usually filled with a color
+  using \ref clear (usually the color is \c Qt::transparent), to remove the contents of the
+  previous frame.
+
+  The simplest paint buffer implementation is \ref QCPPaintBufferPixmap which allows regular
+  software rendering via the raster engine. Hardware accelerated rendering via pixel buffers and
+  frame buffer objects is provided by \ref QCPPaintBufferGlPbuffer and \ref QCPPaintBufferGlFbo.

+/*! \class QCPLayer
+  \brief A layer that may contain objects, to control the rendering order
+
+  The Layering system of QCustomPlot is the mechanism to control the rendering order of the
+  elements inside the plot.
+
+  It is based on the two classes QCPLayer and QCPLayerable. QCustomPlot holds an ordered list of
+  one or more instances of QCPLayer (see QCustomPlot::addLayer, QCustomPlot::layer,
+  QCustomPlot::moveLayer, etc.). When replotting, QCustomPlot goes through the list of layers
+  bottom to top and successively draws the layerables of the layers into the paint buffer(s).
+
+  A QCPLayer contains an ordered list of QCPLayerable instances. QCPLayerable is an abstract base
+  class from which almost all visible objects derive, like axes, grids, graphs, items, etc.
+
+  \section qcplayer-defaultlayers Default layers
+
+  Initially, QCustomPlot has six layers: "background", "grid", "main", "axes", "legend" and
+  "overlay" (in that order). On top is the "overlay" layer, which only contains the QCustomPlot's
+  selection rect (\ref QCustomPlot::selectionRect). The next two layers "axes" and "legend" contain
+  the default axes and legend, so they will be drawn above plottables. In the middle, there is the
+  "main" layer. It is initially empty and set as the current layer (see
+  QCustomPlot::setCurrentLayer). This means, all new plottables, items etc. are created on this
+  layer by default. Then comes the "grid" layer which contains the QCPGrid instances (which belong
+  tightly to QCPAxis, see \ref QCPAxis::grid). The Axis rect background shall be drawn behind
+  everything else, thus the default QCPAxisRect instance is placed on the "background" layer. Of
+  course, the layer affiliation of the individual objects can be changed as required (\ref
+  QCPLayerable::setLayer).
+
+  \section qcplayer-ordering Controlling the rendering order via layers
+
+  Controlling the ordering of layerables in the plot is easy: Create a new layer in the position
+  you want the layerable to be in, e.g. above "main", with \ref QCustomPlot::addLayer. Then set the
+  current layer with \ref QCustomPlot::setCurrentLayer to that new layer and finally create the
+  objects normally. They will be placed on the new layer automatically, due to the current layer
+  setting. Alternatively you could have also ignored the current layer setting and just moved the
+  objects with \ref QCPLayerable::setLayer to the desired layer after creating them.
+
+  It is also possible to move whole layers. For example, If you want the grid to be shown in front
+  of all plottables/items on the "main" layer, just move it above "main" with
+  QCustomPlot::moveLayer.
+
+  The rendering order within one layer is simply by order of creation or insertion. The item
+  created last (or added last to the layer), is drawn on top of all other objects on that layer.
+
+  When a layer is deleted, the objects on it are not deleted with it, but fall on the layer below
+  the deleted layer, see QCustomPlot::removeLayer.
+
+  \section qcplayer-buffering Replotting only a specific layer
+
+  If the layer mode (\ref setMode) is set to \ref lmBuffered, you can replot only this specific
+  layer by calling \ref replot. In certain situations this can provide better replot performance,
+  compared with a full replot of all layers. Upon creation of a new layer, the layer mode is
+  initialized to \ref lmLogical. The only layer that is set to \ref lmBuffered in a new \ref
+  QCustomPlot instance is the "overlay" layer, containing the selection rect.

+  This function applies the default antialiasing setting to the specified \a painter, using the

+  
+  <b>First example:</b> QCPGraph has multiple entities that have an antialiasing setting: The graph

+  setting which can be controlled with QCPItemLine::setAntialiased. (This function is inherited by

+  This function is used to decide whether a click hits a layerable object or not.
+
+  \a pos is a point in pixel coordinates on the QCustomPlot surface. This function returns the
+  shortest pixel distance of this point to the object. If the object is either invisible or the
+  distance couldn't be determined, -1.0 is returned. Further, if \a onlySelectable is true and the
+  object is not selectable, -1.0 is returned, too.
+
+  If the object is represented not by single lines but by an area like a \ref QCPItemText or the
+  bars of a \ref QCPBars plottable, a click inside the area should also be considered a hit. In
+  these cases this function thus returns a constant value greater zero but still below the parent
+  plot's selection tolerance. (typically the selectionTolerance multiplied by 0.99).
+  
+  Providing a constant value for area objects allows selecting line objects even when they are
+  obscured by such area objects, by clicking close to the lines (i.e. closer than
+  0.99*selectionTolerance).
+  
+  The actual setting of the selection state is not done by this function. This is handled by the
+  parent QCustomPlot when the mouseReleaseEvent occurs, and the finally selected object is notified
+  via the \ref selectEvent/\ref deselectEvent methods.
+  
+  \a details is an optional output parameter. Every layerable subclass may place any information
+  in \a details. This information will be passed to \ref selectEvent when the parent QCustomPlot
+  decides on the basis of this selectTest call, that the object was successfully selected. The
+  subsequent call to \ref selectEvent will carry the \a details. This is useful for multi-part
+  objects (like QCPAxis). This way, a possibly complex calculation to decide which part was clicked
+  is only done once in \ref selectTest. The result (i.e. the actually clicked part) can then be
+  placed in \a details. So in the subsequent \ref selectEvent, the decision which part was
+  selected doesn't have to be done a second time for a single selection operation.
+  
+  You may pass 0 as \a details to indicate that you are not interested in those selection details.

+/*! \class QCPDataRange
+  \brief Describes a data range given by begin and end index
+  
+  QCPDataRange holds two integers describing the begin (\ref setBegin) and end (\ref setEnd) index
+  of a contiguous set of data points. The end index points to the data point above the last data point that's part of
+  the data range, similarly to the nomenclature used in standard iterators.
+  
+  Data Ranges are not bound to a certain plottable, thus they can be freely exchanged, created and
+  modified. If a non-contiguous data set shall be described, the class \ref QCPDataSelection is
+  used, which holds and manages multiple instances of \ref QCPDataRange. In most situations, \ref
+  QCPDataSelection is thus used.
+  
+  Both \ref QCPDataRange and \ref QCPDataSelection offer convenience methods to work with them,
+  e.g. \ref bounded, \ref expanded, \ref intersects, \ref intersection, \ref adjusted, \ref
+  contains. Further, addition and subtraction operators (defined in \ref QCPDataSelection) can be
+  used to join/subtract data ranges and data selections (or mixtures), to retrieve a corresponding
+  \ref QCPDataSelection.
+  
+  %QCustomPlot's \ref dataselection "data selection mechanism" is based on \ref QCPDataSelection and
+  QCPDataRange.
+  
+  \note Do not confuse \ref QCPDataRange with \ref QCPRange. A \ref QCPRange describes an interval
+  in floating point plot coordinates, e.g. the current axis range.

+/*! \class QCPDataSelection
+  \brief Describes a data set by holding multiple QCPDataRange instances
+  
+  QCPDataSelection manages multiple instances of QCPDataRange in order to represent any (possibly
+  disjoint) set of data selection.
+  
+  The data selection can be modified with addition and subtraction operators which take
+  QCPDataSelection and QCPDataRange instances, as well as methods such as \ref addDataRange and
+  \ref clear. Read access is provided by \ref dataRange, \ref dataRanges, \ref dataRangeCount, etc.
+  
+  The method \ref simplify is used to join directly adjacent or even overlapping QCPDataRange
+  instances. QCPDataSelection automatically simplifies when using the addition/subtraction
+  operators. The only case when \ref simplify is left to the user, is when calling \ref
+  addDataRange, with the parameter \a simplify explicitly set to false. This is useful if many data
+  ranges will be added to the selection successively and the overhead for simplifying after each
+  iteration shall be avoided. In this case, you should make sure to call \ref simplify after
+  completing the operation.
+  
+  Use \ref enforceType to bring the data selection into a state complying with the constraints for
+  selections defined in \ref QCP::SelectionType.

+/*! \class QCPSelectionRect
+  \brief Provides rect/rubber-band data selection and range zoom interaction
+  
+  QCPSelectionRect is used by QCustomPlot when the \ref QCustomPlot::setSelectionRectMode is not
+  \ref QCP::srmNone. When the user drags the mouse across the plot, the current selection rect
+  instance (\ref QCustomPlot::setSelectionRect) is forwarded these events and makes sure an
+  according rect shape is drawn. At the begin, during, and after completion of the interaction, it
+  emits the corresponding signals \ref started, \ref changed, \ref canceled, and \ref accepted.
+  
+  The QCustomPlot instance connects own slots to the current selection rect instance, in order to
+  react to an accepted selection rect interaction accordingly.
+  
+  \ref isActive can be used to check whether the selection rect is currently active. An ongoing
+  selection interaction can be cancelled programmatically via calling \ref cancel at any time.
+  
+  The appearance of the selection rect can be controlled via \ref setPen and \ref setBrush.
+
+  If you wish to provide custom behaviour, e.g. a different visual representation of the selection
+  rect (\ref QCPSelectionRect::draw), you can subclass QCPSelectionRect and pass an instance of
+  your subclass to \ref QCustomPlot::setSelectionRect.

+/*! \class QCPMarginGroup
+  \brief A margin group allows synchronization of margin sides if working with multiple layout elements.
+  
+  QCPMarginGroup allows you to tie a margin side of two or more layout elements together, such that
+  they will all have the same size, based on the largest required margin in the group.
+  
+  \n
+  \image html QCPMarginGroup.png "Demonstration of QCPMarginGroup"
+  \n
+  
+  In certain situations it is desirable that margins at specific sides are synchronized across
+  layout elements. For example, if one QCPAxisRect is below another one in a grid layout, it will
+  provide a cleaner look to the user if the left and right margins of the two axis rects are of the
+  same size. The left axis of the top axis rect will then be at the same horizontal position as the
+  left axis of the lower axis rect, making them appear aligned. The same applies for the right
+  axes. This is what QCPMarginGroup makes possible.
+  
+  To add/remove a specific side of a layout element to/from a margin group, use the \ref
+  QCPLayoutElement::setMarginGroup method. To completely break apart the margin group, either call
+  \ref clear, or just delete the margin group.
+  
+  \section QCPMarginGroup-example Example
+  
+  First create a margin group:

+  \brief The abstract base class for all objects that form \ref thelayoutsystem "the layout system".
+  
+  This is an abstract base class. As such, it can't be instantiated directly, rather use one of its subclasses.
+  
+  A Layout element is a rectangular object which can be placed in layouts. It has an outer rect
+  (QCPLayoutElement::outerRect) and an inner rect (\ref QCPLayoutElement::rect). The difference
+  between outer and inner rect is called its margin. The margin can either be set to automatic or
+  manual (\ref setAutoMargins) on a per-side basis. If a side is set to manual, that margin can be
+  set explicitly with \ref setMargins and will stay fixed at that value. If it's set to automatic,
+  the layout element subclass will control the value itself (via \ref calculateAutoMargin).
+  
+  Layout elements can be placed in layouts (base class QCPLayout) like QCPLayoutGrid. The top level
+  layout is reachable via \ref QCustomPlot::plotLayout, and is a \ref QCPLayoutGrid. Since \ref
+  QCPLayout itself derives from \ref QCPLayoutElement, layouts can be nested.
+  
+  Thus in QCustomPlot one can divide layout elements into two categories: The ones that are
+  invisible by themselves, because they don't draw anything. Their only purpose is to manage the
+  position and size of other layout elements. This category of layout elements usually use
+  QCPLayout as base class. Then there is the category of layout elements which actually draw
+  something. For example, QCPAxisRect, QCPLegend and QCPTextElement are of this category. This does
+  not necessarily mean that the latter category can't have child layout elements. QCPLegend for
+  instance, actually derives from QCPLayoutGrid and the individual legend items are child layout
+  elements in the grid layout.

+/*! \class QCPLayout
+  \brief The abstract base class for layouts
+  
+  This is an abstract base class for layout elements whose main purpose is to define the position
+  and size of other child layout elements. In most cases, layouts don't draw anything themselves
+  (but there are exceptions to this, e.g. QCPLegend).
+  
+  QCPLayout derives from QCPLayoutElement, and thus can itself be nested in other layouts.
+  
+  QCPLayout introduces a common interface for accessing and manipulating the child elements. Those
+  functions are most notably \ref elementCount, \ref elementAt, \ref takeAt, \ref take, \ref
+  simplify, \ref removeAt, \ref remove and \ref clear. Individual subclasses may add more functions
+  to this interface which are more specialized to the form of the layout. For example, \ref
+  QCPLayoutGrid adds functions that take row and column indices to access cells of the layout grid
+  more conveniently.
+  
+  Since this is an abstract base class, you can't instantiate it directly. Rather use one of its
+  subclasses like QCPLayoutGrid or QCPLayoutInset.
+  
+  For a general introduction to the layout system, see the dedicated documentation page \ref
+  thelayoutsystem "The Layout System".

+/*! \class QCPLayoutGrid
+  \brief A layout that arranges child elements in a grid
+
+  Elements are laid out in a grid with configurable stretch factors (\ref setColumnStretchFactor,
+  \ref setRowStretchFactor) and spacing (\ref setColumnSpacing, \ref setRowSpacing).
+
+  Elements can be added to cells via \ref addElement. The grid is expanded if the specified row or
+  column doesn't exist yet. Whether a cell contains a valid layout element can be checked with \ref
+  hasElement, that element can be retrieved with \ref element. If rows and columns that only have
+  empty cells shall be removed, call \ref simplify. Removal of elements is either done by just
+  adding the element to a different layout or by using the QCPLayout interface \ref take or \ref
+  remove.
+
+  If you use \ref addElement(QCPLayoutElement*) without explicit parameters for \a row and \a
+  column, the grid layout will choose the position according to the current \ref setFillOrder and
+  the wrapping (\ref setWrap).
+
+  Row and column insertion can be performed with \ref insertRow and \ref insertColumn.

+/*! \class QCPAxisTicker
+  \brief The base class tick generator used by QCPAxis to create tick positions and tick labels
+  
+  Each QCPAxis has an internal QCPAxisTicker (or a subclass) in order to generate tick positions
+  and tick labels for the current axis range. The ticker of an axis can be set via \ref
+  QCPAxis::setTicker. Since that method takes a <tt>QSharedPointer<QCPAxisTicker></tt>, multiple
+  axes can share the same ticker instance.
+  
+  This base class generates normal tick coordinates and numeric labels for linear axes. It picks a
+  reasonable tick step (the separation between ticks) which results in readable tick labels. The
+  number of ticks that should be approximately generated can be set via \ref setTickCount.
+  Depending on the current tick step strategy (\ref setTickStepStrategy), the algorithm either
+  sacrifices readability to better match the specified tick count (\ref
+  QCPAxisTicker::tssMeetTickCount) or relaxes the tick count in favor of better tick steps (\ref
+  QCPAxisTicker::tssReadability), which is the default.
+  
+  The following more specialized axis ticker subclasses are available, see details in the
+  respective class documentation:

+  \section axisticker-subclassing Creating own axis tickers
+  
+  Creating own axis tickers can be achieved very easily by sublassing QCPAxisTicker and
+  reimplementing some or all of the available virtual methods.
+
+  In the simplest case you might wish to just generate different tick steps than the other tickers,
+  so you only reimplement the method \ref getTickStep. If you additionally want control over the
+  string that will be shown as tick label, reimplement \ref getTickLabel.
+  
+  If you wish to have complete control, you can generate the tick vectors and tick label vectors
+  yourself by reimplementing \ref createTickVector and \ref createLabelVector. The default
+  implementations use the previously mentioned virtual methods \ref getTickStep and \ref
+  getTickLabel, but your reimplementations don't necessarily need to do so. For example in the case
+  of unequal tick steps, the method \ref getTickStep loses its usefulness and can be ignored.
+  
+  The sub tick count between major ticks can be controlled with \ref getSubTickCount. Full sub tick
+  placement control is obtained by reimplementing \ref createSubTickVector.
+  
+  See the documentation of all these virtual methods in QCPAxisTicker for detailed information
+  about the parameters and expected return values.

+/*! \class QCPAxisTickerDateTime
+  \brief Specialized axis ticker for calendar dates and times as axis ticks
+  
+  \image html axisticker-datetime.png
+  
+  This QCPAxisTicker subclass generates ticks that correspond to real calendar dates and times. The
+  plot axis coordinate is interpreted as Unix Time, so seconds since Epoch (January 1, 1970, 00:00
+  UTC). This is also used for example by QDateTime in the <tt>toTime_t()/setTime_t()</tt> methods
+  with a precision of one second. Since Qt 4.7, millisecond accuracy can be obtained from QDateTime
+  by using <tt>QDateTime::fromMSecsSinceEpoch()/1000.0</tt>. The static methods \ref dateTimeToKey
+  and \ref keyToDateTime conveniently perform this conversion achieving a precision of one
+  millisecond on all Qt versions.
+  
+  The format of the date/time display in the tick labels is controlled with \ref setDateTimeFormat.
+  If a different time spec (time zone) shall be used, see \ref setDateTimeSpec.
+  
+  This ticker produces unequal tick spacing in order to provide intuitive date and time-of-day
+  ticks. For example, if the axis range spans a few years such that there is one tick per year,
+  ticks will be positioned on 1. January of every year. This is intuitive but, due to leap years,
+  will result in slightly unequal tick intervals (visually unnoticeable). The same can be seen in
+  the image above: even though the number of days varies month by month, this ticker generates
+  ticks on the same day of each month.
+  
+  If you would like to change the date/time that is used as a (mathematical) starting date for the
+  ticks, use the \ref setTickOrigin(const QDateTime &origin) method overload, which takes a
+  QDateTime. If you pass 15. July, 9:45 to this method, the yearly ticks will end up on 15. July at
+  9:45 of every year.
+  
+  The ticker can be created and assigned to an axis like this:
+  \snippet documentation/doc-image-generator/mainwindow.cpp axistickerdatetime-creation
+  
+  \note If you rather wish to display relative times in terms of days, hours, minutes, seconds and
+  milliseconds, and are not interested in the intricacies of real calendar dates with months and
+  (leap) years, have a look at QCPAxisTickerTime instead.

+  
+  \image html axisticker-time.png
+  
+  This QCPAxisTicker subclass generates ticks that corresponds to time intervals.
+  
+  The format of the time display in the tick labels is controlled with \ref setTimeFormat and \ref
+  setFieldWidth. The time coordinate is in the unit of seconds with respect to the time coordinate
+  zero. Unlike with QCPAxisTickerDateTime, the ticks don't correspond to a specific calendar date
+  and time.
+  
+  The time can be displayed in milliseconds, seconds, minutes, hours and days. Depending on the
+  largest available unit in the format specified with \ref setTimeFormat, any time spans above will
+  be carried in that largest unit. So for example if the format string is "%m:%s" and a tick at
+  coordinate value 7815 (being 2 hours, 10 minutes and 15 seconds) is created, the resulting tick
+  label will show "130:15" (130 minutes, 15 seconds). If the format string is "%h:%m:%s", the hour
+  unit will be used and the label will thus be "02:10:15". Negative times with respect to the axis
+  zero will carry a leading minus sign.
+  
+  The ticker can be created and assigned to an axis like this:
+  \snippet documentation/doc-image-generator/mainwindow.cpp axistickertime-creation
+  
+  Here is an example of a time axis providing time information in days, hours and minutes. Due to

+  
+  Especially in the case of a log base equal to 10 (the default), it might be desirable to have
+  tick labels in the form of powers of ten without mantissa display. To achieve this, set the
+  number precision (\ref QCPAxis::setNumberPrecision) to zero and the number format (\ref
+  QCPAxis::setNumberFormat) to scientific (exponential) display with beautifully typeset decimal
+  powers, so a format string of <tt>"eb"</tt>. This will result in the following axis tick labels:

+  
+  \a formatCode is a string of one, two or three characters. The first character is identical to

+  format, 'g'/'G' scientific or fixed, whichever is shorter.
+  
+  The second and third characters are optional and specific to QCustomPlot:\n
+  If the first char was 'e' or 'g', numbers are/might be displayed in the scientific format, e.g.
+  "5.5e9", which is ugly in a plot. So when the second char of \a formatCode is set to 'b' (for
+  "beautiful"), those exponential numbers are formatted in a more natural way, i.e. "5.5
+  [multiplication sign] 10 [superscript] 9". By default, the multiplication sign is a centered dot.
+  If instead a cross should be shown (as is usual in the USA), the third char of \a formatCode can
+  be set to 'c'. The inserted multiplication signs are the UTF-8 characters 215 (0xD7) for the
+  cross and 183 (0xB7) for the dot.
+  
+  Examples for \a formatCode:
+  \li \c g normal format code behaviour. If number is small, fixed format is used, if number is large,
+  normal scientific format is used
+  \li \c gb If number is small, fixed format is used, if number is large, scientific format is used with
+  beautifully typeset decimal powers and a dot as multiplication sign
+  \li \c ebc All numbers are in scientific format with beautifully typeset decimal power and a cross as
+  multiplication sign
+  \li \c fb illegal format code, since fixed format doesn't support (or need) beautifully typeset decimal
+  powers. Format code will be reduced to 'f'.
+  \li \c hello illegal format code, since first char is not 'e', 'E', 'f', 'g' or 'G'. Current format

+  at which the label should be drawn.
+  
+  In order to later draw the axis label in a place that doesn't overlap with the tick labels, the
+  largest tick label size is needed. This is acquired by passing a \a tickLabelsSize to the \ref
+  drawTickLabel calls during the process of drawing all tick labels of one axis. In every call, \a
+  tickLabelsSize is expanded, if the drawn label exceeds the value \a tickLabelsSize currently
+  holds.
+  
+  The label is drawn with the font and pen that are currently set on the \a painter. To draw
+  superscripted powers, the font is temporarily made smaller by a fixed factor (see \ref
+  getTickLabelData).

+/*! \class QCPScatterStyle
+  \brief Represents the visual appearance of scatter points
+  
+  This class holds information about shape, color and size of scatter points. In plottables like
+  QCPGraph it is used to store how scatter points shall be drawn. For example, \ref
+  QCPGraph::setScatterStyle takes a QCPScatterStyle instance.
+  
+  A scatter style consists of a shape (\ref setShape), a line color (\ref setPen) and possibly a
+  fill (\ref setBrush), if the shape provides a fillable area. Further, the size of the shape can
+  be controlled with \ref setSize.
+
+  \section QCPScatterStyle-defining Specifying a scatter style
+  
+  You can set all these configurations either by calling the respective functions on an instance:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpscatterstyle-creation-1
+  
+  Or you can use one of the various constructors that take different parameter combinations, making
+  it easy to specify a scatter style in a single call, like so:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpscatterstyle-creation-2
+  
+  \section QCPScatterStyle-undefinedpen Leaving the color/pen up to the plottable
+  
+  There are two constructors which leave the pen undefined: \ref QCPScatterStyle() and \ref
+  QCPScatterStyle(ScatterShape shape, double size). If those constructors are used, a call to \ref
+  isPenDefined will return false. It leads to scatter points that inherit the pen from the
+  plottable that uses the scatter style. Thus, if such a scatter style is passed to QCPGraph, the line
+  color of the graph (\ref QCPGraph::setPen) will be used by the scatter points. This makes
+  it very convenient to set up typical scatter settings:
+  
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpscatterstyle-shortcreation
+
+  Notice that it wasn't even necessary to explicitly call a QCPScatterStyle constructor. This works
+  because QCPScatterStyle provides a constructor that can transform a \ref ScatterShape directly
+  into a QCPScatterStyle instance (that's the \ref QCPScatterStyle(ScatterShape shape, double size)
+  constructor with a default for \a size). In those cases, C++ allows directly supplying a \ref
+  ScatterShape, where actually a QCPScatterStyle is expected.
+  
+  \section QCPScatterStyle-custompath-and-pixmap Custom shapes and pixmaps
+  
+  QCPScatterStyle supports drawing custom shapes and arbitrary pixmaps as scatter points.
+
+  For custom shapes, you can provide a QPainterPath with the desired shape to the \ref
+  setCustomPath function or call the constructor that takes a painter path. The scatter shape will
+  automatically be set to \ref ssCustom.
+  
+  For pixmaps, you call \ref setPixmap with the desired QPixmap. Alternatively you can use the
+  constructor that takes a QPixmap. The scatter shape will automatically be set to \ref ssPixmap.
+  Note that \ref setSize does not influence the appearance of the pixmap.

+  is undefined, the pen of the respective plottable will be used for drawing scatters.

+  
+  Each \ref QCPAbstractPlottable instance has one \ref QCPSelectionDecorator (accessible via \ref
+  QCPAbstractPlottable::selectionDecorator) and uses it when drawing selected segments of its data.
+  
+  The selection decorator controls both pen (\ref setPen) and brush (\ref setBrush), as well as the
+  scatter style (\ref setScatterStyle) if the plottable draws scatters. Since a \ref
+  QCPScatterStyle is itself composed of different properties such as color shape and size, the
+  decorator allows specifying exactly which of those properties shall be used for the selected data
+  point, via \ref setUsedScatterProperties.
+  
+  A \ref QCPSelectionDecorator subclass instance can be passed to a plottable via \ref
+  QCPAbstractPlottable::setSelectionDecorator, allowing greater customizability of the appearance
+  of selected segments.
+  
+  Use \ref copyFrom to easily transfer the settings of one decorator to another one. This is
+  especially useful since plottables take ownership of the passed selection decorator, and thus the
+  same decorator instance can not be passed to multiple plottables.
+  
+  Selection decorators can also themselves perform drawing operations by reimplementing \ref
+  drawDecoration, which is called by the plottable's draw method. The base class \ref
+  QCPSelectionDecorator does not make use of this however. For example, \ref

+/*! \class QCPAbstractPlottable
+  \brief The abstract base class for all data representing objects in a plot.
+
+  It defines a very basic interface like name, pen, brush, visibility etc. Since this class is
+  abstract, it can't be instantiated. Use one of the subclasses or create a subclass yourself to
+  create new ways of displaying data (see "Creating own plottables" below). Plottables that display
+  one-dimensional data (i.e. data points have a single key dimension and one or multiple values at
+  each key) are based off of the template subclass \ref QCPAbstractPlottable1D, see details
+  there.
+  
+  All further specifics are in the subclasses, for example:
+  \li A normal graph with possibly a line and/or scatter points \ref QCPGraph
+  (typically created with \ref QCustomPlot::addGraph)
+  \li A parametric curve: \ref QCPCurve
+  \li A bar chart: \ref QCPBars
+  \li A statistical box plot: \ref QCPStatisticalBox
+  \li A color encoded two-dimensional map: \ref QCPColorMap
+  \li An OHLC/Candlestick chart: \ref QCPFinancial
+  
+  \section plottables-subclassing Creating own plottables
+  
+  Subclassing directly from QCPAbstractPlottable is only recommended if you wish to display
+  two-dimensional data like \ref QCPColorMap, i.e. two logical key dimensions and one (or more)
+  data dimensions. If you want to display data with only one logical key dimension, you should
+  rather derive from \ref QCPAbstractPlottable1D.
+  
+  If subclassing QCPAbstractPlottable directly, these are the pure virtual functions you must
+  implement:
+  \li \ref selectTest
+  \li \ref draw
+  \li \ref drawLegendIcon
+  \li \ref getKeyRange
+  \li \ref getValueRange
+  
+  See the documentation of those functions for what they need to do.
+  
+  For drawing your plot, you can use the \ref coordsToPixels functions to translate a point in plot
+  coordinates to pixel coordinates. This function is quite convenient, because it takes the
+  orientation of the key and value axes into account for you (x and y are swapped when the key axis
+  is vertical and the value axis horizontal). If you are worried about performance (i.e. you need
+  to translate many points in a loop like QCPGraph), you can directly use \ref
+  QCPAxis::coordToPixel. However, you must then take care about the orientation of the axis
+  yourself.
+  
+  Here are some important members you inherit from QCPAbstractPlottable:
+  <table>
+  <tr>
+    <td>QCustomPlot *\b mParentPlot</td>
+    <td>A pointer to the parent QCustomPlot instance. The parent plot is inferred from the axes that are passed in the constructor.</td>
+  </tr><tr>
+    <td>QString \b mName</td>
+    <td>The name of the plottable.</td>
+  </tr><tr>
+    <td>QPen \b mPen</td>
+    <td>The generic pen of the plottable. You should use this pen for the most prominent data representing lines in the plottable
+        (e.g QCPGraph uses this pen for its graph lines and scatters)</td>
+  </tr><tr>
+    <td>QBrush \b mBrush</td>
+    <td>The generic brush of the plottable. You should use this brush for the most prominent fillable structures in the plottable
+        (e.g. QCPGraph uses this brush to control filling under the graph)</td>
+  </tr><tr>
+    <td>QPointer<\ref QCPAxis> \b mKeyAxis, \b mValueAxis</td>
+    <td>The key and value axes this plottable is attached to. Call their QCPAxis::coordToPixel functions to translate coordinates
+        to pixels in either the key or value dimension. Make sure to check whether the pointer is null before using it. If one of
+        the axes is null, don't draw the plottable.</td>

+/*! \class QCPItemAnchor
+  \brief An anchor of an item to which positions can be attached to.
+  
+  An item (QCPAbstractItem) may have one or more anchors. Unlike QCPItemPosition, an anchor doesn't
+  control anything on its item, but provides a way to tie other items via their positions to the
+  anchor.
+
+  For example, a QCPItemRect is defined by its positions \a topLeft and \a bottomRight.
+  Additionally it has various anchors like \a top, \a topRight or \a bottomLeft etc. So you can
+  attach the \a start (which is a QCPItemPosition) of a QCPItemLine to one of the anchors by
+  calling QCPItemPosition::setParentAnchor on \a start, passing the wanted anchor of the
+  QCPItemRect. This way the start of the line will now always follow the respective anchor location
+  on the rect item.
+  
+  Note that QCPItemPosition derives from QCPItemAnchor, so every position can also serve as an
+  anchor to other positions.
+  
+  To learn how to provide anchors in your own item subclasses, see the subclassing section of the
+  QCPAbstractItem documentation.

+/*! \class QCPItemPosition
+  \brief Manages the position of an item.
+  
+  Every item has at least one public QCPItemPosition member pointer which provides ways to position the
+  item on the QCustomPlot surface. Some items have multiple positions, for example QCPItemRect has two:
+  \a topLeft and \a bottomRight.
+
+  QCPItemPosition has a type (\ref PositionType) that can be set with \ref setType. This type
+  defines how coordinates passed to \ref setCoords are to be interpreted, e.g. as absolute pixel
+  coordinates, as plot coordinates of certain axes, etc. For more advanced plots it is also
+  possible to assign different types per X/Y coordinate of the position (see \ref setTypeX, \ref
+  setTypeY). This way an item could be positioned at a fixed pixel distance from the top in the Y
+  direction, while following a plot coordinate in the X direction.
+
+  A QCPItemPosition may have a parent QCPItemAnchor, see \ref setParentAnchor. This way you can tie
+  multiple items together. If the QCPItemPosition has a parent, its coordinates (\ref setCoords)
+  are considered to be absolute pixels in the reference frame of the parent anchor, where (0, 0)
+  means directly ontop of the parent anchor. For example, You could attach the \a start position of
+  a QCPItemLine to the \a bottom anchor of a QCPItemText to make the starting point of the line
+  always be centered under the text label, no matter where the text is moved to. For more advanced
+  plots, it is possible to assign different parent anchors per X/Y coordinate of the position, see
+  \ref setParentAnchorX, \ref setParentAnchorY. This way an item could follow another item in the X
+  direction but stay at a fixed position in the Y direction. Or even follow item A in X, and item B
+  in Y.
+
+  Note that every QCPItemPosition inherits from QCPItemAnchor and thus can itself be used as parent
+  anchor for other positions.
+
+  To set the apparent pixel position on the QCustomPlot surface directly, use \ref setPixelPosition. This
+  works no matter what type this QCPItemPosition is or what parent-child situation it is in, as \ref
+  setPixelPosition transforms the coordinates appropriately, to make the position appear at the specified
+  pixel values.

+/*! \class QCPAbstractItem
+  \brief The abstract base class for all items in a plot.
+  
+  In QCustomPlot, items are supplemental graphical elements that are neither plottables
+  (QCPAbstractPlottable) nor axes (QCPAxis). While plottables are always tied to two axes and thus
+  plot coordinates, items can also be placed in absolute coordinates independent of any axes. Each
+  specific item has at least one QCPItemPosition member which controls the positioning. Some items
+  are defined by more than one coordinate and thus have two or more QCPItemPosition members (For
+  example, QCPItemRect has \a topLeft and \a bottomRight).
+  
+  This abstract base class defines a very basic interface like visibility and clipping. Since this
+  class is abstract, it can't be instantiated. Use one of the subclasses or create a subclass
+  yourself to create new items.
+  
+  The built-in items are:
+  <table>
+  <tr><td>QCPItemLine</td><td>A line defined by a start and an end point. May have different ending styles on each side (e.g. arrows).</td></tr>
+  <tr><td>QCPItemStraightLine</td><td>A straight line defined by a start and a direction point. Unlike QCPItemLine, the straight line is infinitely long and has no endings.</td></tr>
+  <tr><td>QCPItemCurve</td><td>A curve defined by start, end and two intermediate control points. May have different ending styles on each side (e.g. arrows).</td></tr>
+  <tr><td>QCPItemRect</td><td>A rectangle</td></tr>
+  <tr><td>QCPItemEllipse</td><td>An ellipse</td></tr>
+  <tr><td>QCPItemPixmap</td><td>An arbitrary pixmap</td></tr>
+  <tr><td>QCPItemText</td><td>A text label</td></tr>
+  <tr><td>QCPItemBracket</td><td>A bracket which may be used to reference/highlight certain parts in the plot.</td></tr>
+  <tr><td>QCPItemTracer</td><td>An item that can be attached to a QCPGraph and sticks to its data points, given a key coordinate.</td></tr>
+  </table>
+  
+  \section items-clipping Clipping
+
+  Items are by default clipped to the main axis rect (they are only visible inside the axis rect).
+  To make an item visible outside that axis rect, disable clipping via \ref setClipToAxisRect
+  "setClipToAxisRect(false)".
+
+  On the other hand if you want the item to be clipped to a different axis rect, specify it via
+  \ref setClipAxisRect. This clipAxisRect property of an item is only used for clipping behaviour, and
+  in principle is independent of the coordinate axes the item might be tied to via its position
+  members (\ref QCPItemPosition::setAxes). However, it is common that the axis rect for clipping
+  also contains the axes used for the item positions.
+  
+  \section items-using Using items
+  
+  First you instantiate the item you want to use and add it to the plot:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-1
+  by default, the positions of the item are bound to the x- and y-Axis of the plot. So we can just
+  set the plot coordinates where the line should start/end:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-2
+  If we don't want the line to be positioned in plot coordinates but a different coordinate system,
+  e.g. absolute pixel positions on the QCustomPlot surface, we need to change the position type like this:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-3
+  Then we can set the coordinates, this time in pixels:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-4
+  and make the line visible on the entire QCustomPlot, by disabling clipping to the axis rect:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-5
+  
+  For more advanced plots, it is even possible to set different types and parent anchors per X/Y
+  coordinate of an item position, using for example \ref QCPItemPosition::setTypeX or \ref
+  QCPItemPosition::setParentAnchorX. For details, see the documentation of \ref QCPItemPosition.
+  
+  \section items-subclassing Creating own items
+  
+  To create an own item, you implement a subclass of QCPAbstractItem. These are the pure
+  virtual functions, you must implement:
+  \li \ref selectTest
+  \li \ref draw
+  
+  See the documentation of those functions for what they need to do.
+  
+  \subsection items-positioning Allowing the item to be positioned
+  
+  As mentioned, item positions are represented by QCPItemPosition members. Let's assume the new item shall
+  have only one point as its position (as opposed to two like a rect or multiple like a polygon). You then add
+  a public member of type QCPItemPosition like so:
+  
+  \code QCPItemPosition * const myPosition;\endcode
+  
+  the const makes sure the pointer itself can't be modified from the user of your new item (the QCPItemPosition
+  instance it points to, can be modified, of course).
+  The initialization of this pointer is made easy with the \ref createPosition function. Just assign
+  the return value of this function to each QCPItemPosition in the constructor of your item. \ref createPosition
+  takes a string which is the name of the position, typically this is identical to the variable name.
+  For example, the constructor of QCPItemExample could look like this:
+  
+  \code
+  QCPItemExample::QCPItemExample(QCustomPlot *parentPlot) :
+    QCPAbstractItem(parentPlot),
+    myPosition(createPosition("myPosition"))
+  {
+    // other constructor code
+  }
+  \endcode
+  
+  \subsection items-drawing The draw function
+  
+  To give your item a visual representation, reimplement the \ref draw function and use the passed
+  QCPPainter to draw the item. You can retrieve the item position in pixel coordinates from the
+  position member(s) via \ref QCPItemPosition::pixelPosition.
+
+  To optimize performance you should calculate a bounding rect first (don't forget to take the pen
+  width into account), check whether it intersects the \ref clipRect, and only draw the item at all
+  if this is the case.
+  
+  \subsection items-selection The selectTest function
+  
+  Your implementation of the \ref selectTest function may use the helpers \ref
+  QCPVector2D::distanceSquaredToLine and \ref rectDistance. With these, the implementation of the
+  selection test becomes significantly simpler for most items. See the documentation of \ref
+  selectTest for what the function parameters mean and what the function should return.
+  
+  \subsection anchors Providing anchors
+  
+  Providing anchors (QCPItemAnchor) starts off like adding a position. First you create a public
+  member, e.g.
+  
+  \code QCPItemAnchor * const bottom;\endcode
+
+  and create it in the constructor with the \ref createAnchor function, assigning it a name and an
+  anchor id (an integer enumerating all anchors on the item, you may create an own enum for this).
+  Since anchors can be placed anywhere, relative to the item's position(s), your item needs to
+  provide the position of every anchor with the reimplementation of the \ref anchorPixelPosition(int
+  anchorId) function.
+  
+  In essence the QCPItemAnchor is merely an intermediary that itself asks your item for the pixel
+  position when anything attached to the anchor needs to know the coordinates.

+  QCPAxisRect::setRangeDrag, \ref QCPAxisRect::setRangeZoom, \ref QCPAxisRect::setRangeDragAxes,
+  \ref QCPAxisRect::setRangeZoomAxes.
+  
+  <b>Plottable data selection</b> is controlled by \ref QCP::iSelectPlottables. If \ref
+  QCP::iSelectPlottables is set, the user may select plottables (graphs, curves, bars,...) and
+  their data by clicking on them or in their vicinity (\ref setSelectionTolerance). Whether the
+  user can actually select a plottable and its data can further be restricted with the \ref
+  QCPAbstractPlottable::setSelectable method on the specific plottable. For details, see the
+  special page about the \ref dataselection "data selection mechanism". To retrieve a list of all
+  currently selected plottables, call \ref selectedPlottables. If you're only interested in
+  QCPGraphs, you may use the convenience function \ref selectedGraphs.
+  
+  <b>Item selection</b> is controlled by \ref QCP::iSelectItems. If \ref QCP::iSelectItems is set, the user
+  may select items (QCPItemLine, QCPItemText,...) by clicking on them or in their vicinity. To find
+  out whether a specific item is selected, call QCPAbstractItem::selected(). To retrieve a list of
+  all currently selected items, call \ref selectedItems.
+  
+  <b>Axis selection</b> is controlled with \ref QCP::iSelectAxes. If \ref QCP::iSelectAxes is set, the user
+  may select parts of the axes by clicking on them. What parts exactly (e.g. Axis base line, tick
+  labels, axis label) are selectable can be controlled via \ref QCPAxis::setSelectableParts for
+  each axis. To retrieve a list of all axes that currently contain selected parts, call \ref
+  selectedAxes. Which parts of an axis are selected, can be retrieved with QCPAxis::selectedParts().
+  
+  <b>Legend selection</b> is controlled with \ref QCP::iSelectLegend. If this is set, the user may
+  select the legend itself or individual items by clicking on them. What parts exactly are
+  selectable can be controlled via \ref QCPLegend::setSelectableParts. To find out whether the
+  legend or any of its child items are selected, check the value of QCPLegend::selectedParts. To
+  find out which child items are selected, call \ref QCPLegend::selectedItems.

+  QCPTextElement, or your own layerable subclasses) is controlled with \ref QCP::iSelectOther. If set, the
+  user may select those objects by clicking on them. To find out which are currently selected, you
+  need to check their selected state explicitly.
+

+  \warning This is still an experimental feature and its performance depends on the system that it

+  might cause context conflicts on some systems.
+  
+  This method allows to enable OpenGL plot rendering, for increased plotting performance of
+  graphically demanding plots (thick lines, translucent fills, etc.).
+
+  If \a enabled is set to true, QCustomPlot will try to initialize OpenGL and, if successful,
+  continue plotting with hardware acceleration. The parameter \a multisampling controls how many
+  samples will be used per pixel, it essentially controls the antialiasing quality. If \a
+  multisampling is set too high for the current graphics hardware, the maximum allowed value will
+  be used.
+
+  You can test whether switching to OpenGL rendering was successful by checking whether the
+  according getter \a QCustomPlot::openGl() returns true. If the OpenGL initialization fails,
+  rendering continues with the regular software rasterizer, and an according qDebug output is
+  generated.
+
+  If switching to OpenGL was successful, this method disables label caching (\ref setPlottingHint
+  "setPlottingHint(QCP::phCacheLabels, false)") and turns on QCustomPlot's antialiasing override
+  for all elements (\ref setAntialiasedElements "setAntialiasedElements(QCP::aeAll)"), leading to a

+  settings are restored to what they were before OpenGL was enabled, if they weren't altered in the
+  meantime.
+
+  \note OpenGL support is only enabled if QCustomPlot is compiled with the macro \c QCUSTOMPLOT_USE_OPENGL
+  defined. This define must be set before including the QCustomPlot header both during compilation
+  of the QCustomPlot library as well as when compiling your application. It is best to just include
+  the line <tt>DEFINES += QCUSTOMPLOT_USE_OPENGL</tt> in the respective qmake project files.
+  \note If you are using a Qt version before 5.0, you must also add the module "opengl" to your \c

+
+  The parameter \a refreshPriority can be used to fine-tune the timing of the replot. For example
+  if your application calls \ref replot very quickly in succession (e.g. multiple independent

+  replot with this priority will only cause a single replot, avoiding redundant replots and
+  improving performance.
+
+  Under a few circumstances, QCustomPlot causes a replot by itself. Those are resize events of the
+  QCustomPlot widget and user interactions (object selection and range dragging/zooming).
+
+  Before the replot happens, the signal \ref beforeReplot is emitted. After the replot, \ref
+  afterReplot is emitted. It is safe to mutually connect the replot slot with any of those two
+  signals on two QCustomPlots to make them replot synchronously, it won't cause an infinite
+  recursion.
+
+  If a layer is in mode \ref QCPLayer::lmBuffered (\ref QCPLayer::setMode), it is also possible to

+/*! \class QCPColorGradient
+  \brief Defines a color gradient for use with e.g. \ref QCPColorMap
+  
+  This class describes a color gradient which can be used to encode data with color. For example,
+  QCPColorMap and QCPColorScale have \ref QCPColorMap::setGradient "setGradient" methods which
+  take an instance of this class. Colors are set with \ref setColorStopAt(double position, const QColor &color)
+  with a \a position from 0 to 1. In between these defined color positions, the
+  color will be interpolated linearly either in RGB or HSV space, see \ref setColorInterpolation.
+
+  Alternatively, load one of the preset color gradients shown in the image below, with \ref
+  loadPreset, or by directly specifying the preset in the constructor.
+  
+  Apart from red, green and blue components, the gradient also interpolates the alpha values of the
+  configured color stops. This allows to display some portions of the data range as transparent in
+  the plot.
+  
+  \image html QCPColorGradient.png
+  
+  The \ref QCPColorGradient(GradientPreset preset) constructor allows directly converting a \ref
+  GradientPreset to a QCPColorGradient. This means that you can directly pass \ref GradientPreset
+  to all the \a setGradient methods, e.g.:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorgradient-setgradient
+  
+  The total number of levels used in the gradient can be set with \ref setLevelCount. Whether the
+  color gradient shall be applied periodically (wrapping around) to data values that lie outside
+  the data range specified on the plottable instance can be controlled with \ref setPeriodic.

+/*! \class QCPAxisRect
+  \brief Holds multiple axes and arranges them in a rectangular shape.
+  
+  This class represents an axis rect, a rectangular area that is bounded on all sides with an
+  arbitrary number of axes.
+  
+  Initially QCustomPlot has one axis rect, accessible via QCustomPlot::axisRect(). However, the
+  layout system allows to have multiple axis rects, e.g. arranged in a grid layout
+  (QCustomPlot::plotLayout).
+  
+  By default, QCPAxisRect comes with four axes, at bottom, top, left and right. They can be
+  accessed via \ref axis by providing the respective axis type (\ref QCPAxis::AxisType) and index.
+  If you need all axes in the axis rect, use \ref axes. The top and right axes are set to be
+  invisible initially (QCPAxis::setVisible). To add more axes to a side, use \ref addAxis or \ref
+  addAxes. To remove an axis, use \ref removeAxis.
+  
+  The axis rect layerable itself only draws a background pixmap or color, if specified (\ref
+  setBackground). It is placed on the "background" layer initially (see \ref QCPLayer for an
+  explanation of the QCustomPlot layer system). The axes that are held by the axis rect can be
+  placed on other layers, independently of the axis rect.
+  
+  Every axis rect has a child layout of type \ref QCPLayoutInset. It is accessible via \ref
+  insetLayout and can be used to have other layout elements (or even other layouts with multiple
+  elements) hovering inside the axis rect.
+  
+  If an axis rect is clicked and dragged, it processes this by moving certain axis ranges. The
+  behaviour can be controlled with \ref setRangeDrag and \ref setRangeDragAxes. If the mouse wheel
+  is scrolled while the cursor is on the axis rect, certain axes are scaled. This is controllable
+  via \ref setRangeZoom, \ref setRangeZoomAxes and \ref setRangeZoomFactor. These interactions are
+  only enabled if \ref QCustomPlot::setInteractions contains \ref QCP::iRangeDrag and \ref
+  QCP::iRangeZoom.

+/*! \class QCPLegend
+  \brief Manages a legend inside a QCustomPlot.
+
+  A legend is a small box somewhere in the plot which lists plottables with their name and icon.
+
+  A legend is populated with legend items by calling \ref QCPAbstractPlottable::addToLegend on the
+  plottable, for which a legend item shall be created. In the case of the main legend (\ref
+  QCustomPlot::legend), simply adding plottables to the plot while \ref
+  QCustomPlot::setAutoAddPlottableToLegend is set to true (the default) creates corresponding
+  legend items. The legend item associated with a certain plottable can be removed with \ref
+  QCPAbstractPlottable::removeFromLegend. However, QCPLegend also offers an interface to add and
+  manipulate legend items directly: \ref item, \ref itemWithPlottable, \ref itemCount, \ref
+  addItem, \ref removeItem, etc.
+
+  Since \ref QCPLegend derives from \ref QCPLayoutGrid, it can be placed in any position a \ref
+  QCPLayoutElement may be positioned. The legend items are themselves \ref QCPLayoutElement
+  "QCPLayoutElements" which are placed in the grid layout of the legend. \ref QCPLegend only adds
+  an interface specialized for handling child elements of type \ref QCPAbstractLegendItem, as
+  mentioned above. In principle, any other layout elements may also be added to a legend via the
+  normal \ref QCPLayoutGrid interface. See the special page about \link thelayoutsystem The Layout
+  System\endlink for examples on how to add other elements to the legend and move it outside the axis
+  rect.
+
+  Use the methods \ref setFillOrder and \ref setWrap inherited from \ref QCPLayoutGrid to control
+  in which order (column first or row first) the legend is filled up when calling \ref addItem, and
+  at which column or row wrapping occurs.
+
+  By default, every QCustomPlot has one legend (\ref QCustomPlot::legend) which is placed in the
+  inset layout of the main axis rect (\ref QCPAxisRect::insetLayout). To move the legend to another
+  position inside the axis rect, use the methods of the \ref QCPLayoutInset. To move the legend
+  outside of the axis rect, place it anywhere else with the \ref QCPLayout/\ref QCPLayoutElement

+/*! \class QCPColorScale
+  \brief A color scale for use with color coding data such as QCPColorMap
+  
+  This layout element can be placed on the plot to correlate a color gradient with data values. It
+  is usually used in combination with one or multiple \ref QCPColorMap "QCPColorMaps".
+
+  \image html QCPColorScale.png
+  
+  The color scale can be either horizontal or vertical, as shown in the image above. The
+  orientation and the side where the numbers appear is controlled with \ref setType.
+  
+  Use \ref QCPColorMap::setColorScale to connect a color map with a color scale. Once they are
+  connected, they share their gradient, data range and data scale type (\ref setGradient, \ref
+  setDataRange, \ref setDataScaleType). Multiple color maps may be associated with a single color
+  scale, to make them all synchronize these properties.
+  
+  To have finer control over the number display and axis behaviour, you can directly access the
+  \ref axis. See the documentation of QCPAxis for details about configuring axes. For example, if
+  you want to change the number of automatically generated ticks, call
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorscale-tickcount
+  
+  Placing a color scale next to the main axis rect works like with any other layout element:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorscale-creation
+  In this case we have placed it to the right of the default axis rect, so it wasn't necessary to
+  call \ref setType, since \ref QCPAxis::atRight is already the default. The text next to the color
+  scale can be set with \ref setLabel.
+  
+  For optimum appearance (like in the image above), it may be desirable to line up the axis rect and
+  the borders of the color scale. Use a \ref QCPMarginGroup to achieve this:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorscale-margingroup
+  
+  Color scales are initialized with a non-zero minimum top and bottom margin (\ref
+  setMinimumMargins), because vertical color scales are most common and the minimum top/bottom
+  margin makes sure it keeps some distance to the top/bottom widget border. So if you change to a
+  horizontal color scale by setting \ref setType to \ref QCPAxis::atBottom or \ref QCPAxis::atTop, you
+  might want to also change the minimum margins accordingly, e.g. <tt>setMinimumMargins(QMargins(6, 0, 6, 0))</tt>.

+
+/*! \fn QCPAxis *QCPColorScale::axis() const
+  
+  Returns the internal \ref QCPAxis instance of this color scale. You can access it to alter the
+  appearance and behaviour of the axis. \ref QCPColorScale duplicates some properties in its
+  interface for convenience. Those are \ref setDataRange (\ref QCPAxis::setRange), \ref
+  setDataScaleType (\ref QCPAxis::setScaleType), and the method \ref setLabel (\ref
+  QCPAxis::setLabel). As they each are connected, it does not matter whether you use the method on
+  the QCPColorScale or on its QCPAxis.
+  
+  If the type of the color scale is changed with \ref setType, the axis returned by this method
+  will change, too, to either the left, right, bottom or top axis, depending on which type was set.

+  \brief A plottable representing a graph in a plot.
+
+  \image html QCPGraph.png
+  
+  Usually you create new graphs by calling QCustomPlot::addGraph. The resulting instance can be
+  accessed via QCustomPlot::graph.
+
+  To plot data, assign it with the \ref setData or \ref addData functions. Alternatively, you can
+  also access and modify the data via the \ref data method, which returns a pointer to the internal
+  \ref QCPGraphDataContainer.
+  
+  Graphs are used to display single-valued data. Single-valued means that there should only be one
+  data point per unique key coordinate. In other words, the graph can't have \a loops. If you do
+  want to plot non-single-valued curves, rather use the QCPCurve plottable.
+  
+  Gaps in the graph line can be created by adding data points with NaN as value
+  (<tt>qQNaN()</tt> or <tt>std::numeric_limits<double>::quiet_NaN()</tt>) in between the two data points that shall be
+  separated.
+  
+  \section qcpgraph-appearance Changing the appearance
+  
+  The appearance of the graph is mainly determined by the line style, scatter style, brush and pen
+  of the graph (\ref setLineStyle, \ref setScatterStyle, \ref setBrush, \ref setPen).
+  
+  \subsection filling Filling under or between graphs
+  
+  QCPGraph knows two types of fills: Normal graph fills towards the zero-value-line parallel to
+  the key axis of the graph, and fills between two graphs, called channel fills. To enable a fill,
+  just set a brush with \ref setBrush which is neither Qt::NoBrush nor fully transparent.
+  
+  By default, a normal fill towards the zero-value-line will be drawn. To set up a channel fill
+  between this graph and another one, call \ref setChannelFillGraph with the other graph as
+  parameter.

+  
+  \image html adaptive-sampling-scatter.png "A scatter plot of 100,000 points without and with adaptive sampling"

+  Care must be taken when using high-density scatter plots in combination with adaptive sampling.
+  The adaptive sampling algorithm treats scatter plots more carefully than line plots which still
+  gives a significant reduction of replot times, but not quite as much as for line plots. This is
+  because scatter plots inherently need more data points to be preserved in order to still resemble
+  the original, non-adaptive-sampling plot. As shown above, the results still aren't quite
+  identical, as banding occurs for the outer data points. This is in fact intentional, such that
+  the boundaries of the data cloud stay visible to the viewer. How strong the banding appears,
+  depends on the point density, i.e. the number of points in the plot.
+  
+  For some situations with scatter plots it might thus be desirable to manually turn adaptive
+  sampling off. For example, when saving the plot to disk. This can be achieved by setting \a
+  enabled to false before issuing a command like \ref QCustomPlot::savePng, and setting \a enabled

+  \brief A plottable representing a parametric curve in a plot.
+  
+  \image html QCPCurve.png
+  
+  Unlike QCPGraph, plottables of this type may have multiple points with the same key coordinate,
+  so their visual representation can have \a loops. This is realized by introducing a third
+  coordinate \a t, which defines the order of the points described by the other two coordinates \a
+  x and \a y.
+
+  To plot data, assign it with the \ref setData or \ref addData functions. Alternatively, you can
+  also access and modify the curve's data via the \ref data method, which returns a pointer to the
+  internal \ref QCPCurveDataContainer.
+  
+  Gaps in the curve can be created by adding data points with NaN as key and value
+  (<tt>qQNaN()</tt> or <tt>std::numeric_limits<double>::quiet_NaN()</tt>) in between the two data points that shall be
+  separated.
+  
+  \section qcpcurve-appearance Changing the appearance
+  
+  The appearance of the curve is determined by the pen and the brush (\ref setPen, \ref setBrush).
+  
+  \section qcpcurve-usage Usage
+  
+  Like all data representing objects in QCustomPlot, the QCPCurve is a plottable
+  (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
+  (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
+  
+  Usually, you first create an instance:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcurve-creation-1
+  which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot instance takes
+  ownership of the plottable, so do not delete it manually but use QCustomPlot::removePlottable() instead.
+  The newly created plottable can be modified, e.g.:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcurve-creation-2

+  extra points at the corners of region 5 (see \ref getRegion) such that the optimized segment
+  doesn't unintentionally cut through the visible area of the axis rect and create plot artifacts.
+  This method provides these points that must be added, assuming the original segment doesn't
+  start, end, or traverse region 5. (Corner points where region 5 is traversed are calculated by
+  \ref getTraverseCornerPoints.)
+  
+  For example, consider a segment which directly goes from region 4 to 2 but originally is far out
+  to the top left such that it doesn't cross region 5. Naively optimizing these points by
+  projecting them on the top and left borders of region 5 will create a segment that surely crosses
+  5, creating a visual artifact in the plot. This method prevents this by providing extra points at
+  the top left corner, making the optimized curve correctly pass from region 4 to 1 to 2 without
+  traversing 5.

+

+  necessary to add an optimized corner point there (very similar to the job \ref

+  
+  As an example, consider a segment going from region 1 to region 6, traversing the lower left
+  corner of region 5. In this configuration, the segment additionally crosses the border between
+  region 1 and 2 before entering region 5. This makes it necessary to add an additional point in
+  the top left corner, before adding the optimized traverse points. So in this case, the output
+  parameter \a beforeTraverse will contain the top left corner point, and \a afterTraverse will be
+  empty.
+  
+  In some cases, such as when going from region 1 to 9, it may even be necessary to add additional
+  corner points before and after the traverse. Then both \a beforeTraverse and \a afterTraverse
+  return the respective corner points.

+  \brief Groups multiple QCPBars together so they appear side by side
+  
+  \image html QCPBarsGroup.png
+  
+  When showing multiple QCPBars in one plot which have bars at identical keys, it may be desirable
+  to have them appearing next to each other at each key. This is what adding the respective QCPBars
+  plottables to a QCPBarsGroup achieves. (An alternative approach is to stack them on top of each
+  other, see \ref QCPBars::moveAbove.)
+  
+  \section qcpbarsgroup-usage Usage
+  
+  To add a QCPBars plottable to the group, create a new group and then add the respective bars
+  intances:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpbarsgroup-creation
+  Alternatively to appending to the group like shown above, you can also set the group on the
+  QCPBars plottable via \ref QCPBars::setBarsGroup.
+  
+  The spacing between the bars can be configured via \ref setSpacingType and \ref setSpacing. The
+  bars in this group appear in the plot in the order they were appended. To insert a bars plottable
+  at a certain index position, or to reposition a bars plottable which is already in the group, use
+  \ref insert.
+  
+  To remove specific bars from the group, use either \ref remove or call \ref
+  QCPBars::setBarsGroup "QCPBars::setBarsGroup(0)" on the respective bars plottable.
+  
+  To clear the entire group, call \ref clear, or simply delete the group.

+  \brief A plottable representing a bar chart in a plot.
+
+  \image html QCPBars.png
+  
+  To plot data, assign it with the \ref setData or \ref addData functions.
+  
+  \section qcpbars-appearance Changing the appearance
+  
+  The appearance of the bars is determined by the pen and the brush (\ref setPen, \ref setBrush).
+  The width of the individual bars can be controlled with \ref setWidthType and \ref setWidth.
+  
+  Bar charts are stackable. This means, two QCPBars plottables can be placed on top of each other
+  (see \ref QCPBars::moveAbove). So when two bars are at the same key position, they will appear
+  stacked.
+  
+  If you would like to group multiple QCPBars plottables together so they appear side by side as
+  shown below, use QCPBarsGroup.
+  
+  \image html QCPBarsGroup.png
+  
+  \section qcpbars-usage Usage
+  
+  Like all data representing objects in QCustomPlot, the QCPBars is a plottable
+  (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
+  (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
+  
+  Usually, you first create an instance:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpbars-creation-1
+  which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot instance takes
+  ownership of the plottable, so do not delete it manually but use QCustomPlot::removePlottable() instead.
+  The newly created plottable can be modified, e.g.:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpbars-creation-2

+/*! \class QCPStatisticalBox
+  \brief A plottable representing a single statistical box in a plot.
+
+  \image html QCPStatisticalBox.png
+  
+  To plot data, assign it with the \ref setData or \ref addData functions. Alternatively, you can
+  also access and modify the data via the \ref data method, which returns a pointer to the internal
+  \ref QCPStatisticalBoxDataContainer.
+  
+  Additionally each data point can itself have a list of outliers, drawn as scatter points at the
+  key coordinate of the respective statistical box data point. They can either be set by using the
+  respective \ref addData(double,double,double,double,double,double,const QVector<double>&)
+  "addData" method or accessing the individual data points through \ref data, and setting the
+  <tt>QVector<double> outliers</tt> of the data points directly.
+  
+  \section qcpstatisticalbox-appearance Changing the appearance
+  
+  The appearance of each data point box, ranging from the lower to the upper quartile, is
+  controlled via \ref setPen and \ref setBrush. You may change the width of the boxes with \ref
+  setWidth in plot coordinates.
+
+  Each data point's visual representation also consists of two whiskers. Whiskers are the lines
+  which reach from the upper quartile to the maximum, and from the lower quartile to the minimum.
+  The appearance of the whiskers can be modified with: \ref setWhiskerPen, \ref setWhiskerBarPen,
+  \ref setWhiskerWidth. The whisker width is the width of the bar perpendicular to the whisker at
+  the top (for maximum) and bottom (for minimum). If the whisker pen is changed, make sure to set
+  the \c capStyle to \c Qt::FlatCap. Otherwise the backbone line might exceed the whisker bars by a
+  few pixels due to the pen cap being not perfectly flat.
+  
+  The median indicator line inside the box has its own pen, \ref setMedianPen.
+  
+  The outlier data points are drawn as normal scatter points. Their look can be controlled with
+  \ref setOutlierStyle
+  
+  \section qcpstatisticalbox-usage Usage
+  
+  Like all data representing objects in QCustomPlot, the QCPStatisticalBox is a plottable
+  (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
+  (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
+  
+  Usually, you first create an instance:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpstatisticalbox-creation-1
+  which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot instance takes
+  ownership of the plottable, so do not delete it manually but use QCustomPlot::removePlottable() instead.
+  The newly created plottable can be modified, e.g.:

+/*! \class QCPColorMapData
+  \brief Holds the two-dimensional data of a QCPColorMap plottable.
+  
+  This class is a data storage for \ref QCPColorMap. It holds a two-dimensional array, which \ref
+  QCPColorMap then displays as a 2D image in the plot, where the array values are represented by a
+  color, depending on the value.
+  
+  The size of the array can be controlled via \ref setSize (or \ref setKeySize, \ref setValueSize).
+  Which plot coordinates these cells correspond to can be configured with \ref setRange (or \ref
+  setKeyRange, \ref setValueRange).
+  
+  The data cells can be accessed in two ways: They can be directly addressed by an integer index
+  with \ref setCell. This is the fastest method. Alternatively, they can be addressed by their plot
+  coordinate with \ref setData. plot coordinate to cell index transformations and vice versa are
+  provided by the functions \ref coordToCell and \ref cellToCoord.
+  
+  A \ref QCPColorMapData also holds an on-demand two-dimensional array of alpha values which (if
+  allocated) has the same size as the data map. It can be accessed via \ref setAlpha, \ref
+  fillAlpha and \ref clearAlpha. The memory for the alpha map is only allocated if needed, i.e. on
+  the first call of \ref setAlpha. \ref clearAlpha restores full opacity and frees the alpha map.
+  
+  This class also buffers the minimum and maximum values that are in the data set, to provide
+  QCPColorMap::rescaleDataRange with the necessary information quickly. Setting a cell to a value
+  that is greater than the current maximum increases this maximum to the new value. However,
+  setting the cell that currently holds the maximum value to a smaller value doesn't decrease the
+  maximum again, because finding the true new maximum would require going through the entire data
+  array, which might be time consuming. The same holds for the data minimum. This functionality is
+  given by \ref recalculateDataBounds, such that you can decide when it is sensible to find the
+  true current minimum and maximum. The method QCPColorMap::rescaleDataRange offers a convenience
+  parameter \a recalculateDataBounds which may be set to true to automatically call \ref
+  recalculateDataBounds internally.

+/*! \class QCPColorMap
+  \brief A plottable representing a two-dimensional color map in a plot.
+
+  \image html QCPColorMap.png
+  
+  The data is stored in the class \ref QCPColorMapData, which can be accessed via the data()
+  method.
+  
+  A color map has three dimensions to represent a data point: The \a key dimension, the \a value
+  dimension and the \a data dimension. As with other plottables such as graphs, \a key and \a value
+  correspond to two orthogonal axes on the QCustomPlot surface that you specify in the QCPColorMap
+  constructor. The \a data dimension however is encoded as the color of the point at (\a key, \a
+  value).
+
+  Set the number of points (or \a cells) in the key/value dimension via \ref
+  QCPColorMapData::setSize. The plot coordinate range over which these points will be displayed is
+  specified via \ref QCPColorMapData::setRange. The first cell will be centered on the lower range
+  boundary and the last cell will be centered on the upper range boundary. The data can be set by
+  either accessing the cells directly with QCPColorMapData::setCell or by addressing the cells via
+  their plot coordinates with \ref QCPColorMapData::setData. If possible, you should prefer
+  setCell, since it doesn't need to do any coordinate transformation and thus performs a bit
+  better.
+  
+  The cell with index (0, 0) is at the bottom left, if the color map uses normal (i.e. not reversed)
+  key and value axes.
+  
+  To show the user which colors correspond to which \a data values, a \ref QCPColorScale is
+  typically placed to the right of the axis rect. See the documentation there for details on how to
+  add and use a color scale.
+  
+  \section qcpcolormap-appearance Changing the appearance
+  
+  The central part of the appearance is the color gradient, which can be specified via \ref
+  setGradient. See the documentation of \ref QCPColorGradient for details on configuring a color
+  gradient.
+  
+  The \a data range that is mapped to the colors of the gradient can be specified with \ref
+  setDataRange. To make the data range encompass the whole data set minimum to maximum, call \ref
+  rescaleDataRange.
+  
+  \section qcpcolormap-transparency Transparency
+  
+  Transparency in color maps can be achieved by two mechanisms. On one hand, you can specify alpha
+  values for color stops of the \ref QCPColorGradient, via the regular QColor interface. This will
+  cause the color map data which gets mapped to colors around those color stops to appear with the
+  accordingly interpolated transparency.
+  
+  On the other hand you can also directly apply an alpha value to each cell independent of its
+  data, by using the alpha map feature of \ref QCPColorMapData. The relevant methods are \ref
+  QCPColorMapData::setAlpha, QCPColorMapData::fillAlpha and \ref QCPColorMapData::clearAlpha().
+  
+  The two transparencies will be joined together in the plot and otherwise not interfere with each
+  other. They are mixed in a multiplicative matter, so an alpha of e.g. 50% (128/255) in both modes
+  simultaneously, will result in a total transparency of 25% (64/255).
+  
+  \section qcpcolormap-usage Usage
+  
+  Like all data representing objects in QCustomPlot, the QCPColorMap is a plottable
+  (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
+  (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
+  
+  Usually, you first create an instance:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolormap-creation-1
+  which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot instance takes
+  ownership of the plottable, so do not delete it manually but use QCustomPlot::removePlottable() instead.
+  The newly created plottable can be modified, e.g.:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolormap-creation-2
+  
+  \note The QCPColorMap always displays the data at equal key/value intervals, even if the key or
+  value axis is set to a logarithmic scaling. If you want to use QCPColorMap with logarithmic axes,
+  you shouldn't use the \ref QCPColorMapData::setData method as it uses a linear transformation to
+  determine the cell index. Rather directly access the cell index with \ref
+  QCPColorMapData::setCell.

+/*! \class QCPFinancial
+  \brief A plottable representing a financial stock chart
+
+  \image html QCPFinancial.png
+
+  This plottable represents time series data binned to certain intervals, mainly used for stock
+  charts. The two common representations OHLC (Open-High-Low-Close) bars and Candlesticks can be
+  set via \ref setChartStyle.
+
+  The data is passed via \ref setData as a set of open/high/low/close values at certain keys
+  (typically times). This means the data must be already binned appropriately. If data is only
+  available as a series of values (e.g. \a price against \a time), you can use the static
+  convenience function \ref timeSeriesToOhlc to generate binned OHLC-data which can then be passed
+  to \ref setData.
+
+  The width of the OHLC bars/candlesticks can be controlled with \ref setWidth and \ref
+  setWidthType. A typical choice is to set the width type to \ref wtPlotCoords (the default) and
+  the width to (or slightly less than) one time bin interval width.
+
+  \section qcpfinancial-appearance Changing the appearance
+
+  Charts can be either single- or two-colored (\ref setTwoColored). If set to be single-colored,
+  lines are drawn with the plottable's pen (\ref setPen) and fills with the brush (\ref setBrush).
+
+  If set to two-colored, positive changes of the value during an interval (\a close >= \a open) are
+  represented with a different pen and brush than negative changes (\a close < \a open). These can
+  be configured with \ref setPenPositive, \ref setPenNegative, \ref setBrushPositive, and \ref
+  setBrushNegative. In two-colored mode, the normal plottable pen/brush is ignored. Upon selection
+  however, the normal selected pen/brush (provided by the \ref selectionDecorator) is used,
+  irrespective of whether the chart is single- or two-colored.
+
+  \section qcpfinancial-usage Usage
+
+  Like all data representing objects in QCustomPlot, the QCPFinancial is a plottable
+  (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
+  (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
+
+  Usually, you first create an instance:
+
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpfinancial-creation-1
+  which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot
+  instance takes ownership of the plottable, so do not delete it manually but use
+  QCustomPlot::removePlottable() instead. The newly created plottable can be modified, e.g.:
+
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpfinancial-creation-2
+  Here we have used the static helper method \ref timeSeriesToOhlc, to turn a time-price data
+  series into a 24-hour binned open-high-low-close data series as QCPFinancial uses.

+
+  The \ref QCPErrorBars plottable can be attached to other one-dimensional plottables (e.g. \ref
+  QCPGraph, \ref QCPCurve, \ref QCPBars, etc.) and equips them with error bars.
+
+  Use \ref setDataPlottable to define for which plottable the \ref QCPErrorBars shall display the
+  error bars. The orientation of the error bars can be controlled with \ref setErrorType.
+
+  By using \ref setData, you can supply the actual error data, either as symmetric error or
+  plus/minus asymmetric errors. \ref QCPErrorBars only stores the error data. The absolute
+  key/value position of each error bar will be adopted from the configured data plottable. The
+  error data of the \ref QCPErrorBars are associated one-to-one via their index to the data points
+  of the data plottable. You can directly access and manipulate the error bar data via \ref data.
+
+  Set either of the plus/minus errors to NaN (<tt>qQNaN()</tt> or
+  <tt>std::numeric_limits<double>::quiet_NaN()</tt>) to not show the respective error bar on the data point at
+  that index.
+
+  \section qcperrorbars-appearance Changing the appearance
+
+  The appearance of the error bars is defined by the pen (\ref setPen), and the width of the
+  whiskers (\ref setWhiskerWidth). Further, the error bar backbones may leave a gap around the data
+  point center to prevent that error bars are drawn too close to or even through scatter points.

+/*! \class QCPItemTracer
+  \brief Item that sticks to QCPGraph data points
+
+  \image html QCPItemTracer.png "Tracer example. Blue dotted circles are anchors, solid blue discs are positions."
+
+  The tracer can be connected with a QCPGraph via \ref setGraph. Then it will automatically adopt
+  the coordinate axes of the graph and update its \a position to be on the graph's data. This means
+  the key stays controllable via \ref setGraphKey, but the value will follow the graph data. If a
+  QCPGraph is connected, note that setting the coordinates of the tracer item directly via \a
+  position will have no effect because they will be overriden in the next redraw (this is when the
+  coordinate update happens).
+  
+  If the specified key in \ref setGraphKey is outside the key bounds of the graph, the tracer will
+  stay at the corresponding end of the graph.
+  
+  With \ref setInterpolating you may specify whether the tracer may only stay exactly on data
+  points or whether it interpolates data points linearly, if given a key that lies between two data
+  points of the graph.
+  
+  The tracer has different visual styles, see \ref setStyle. It is also possible to make the tracer
+  have no own visual appearance (set the style to \ref tsNone), and just connect other item
+  positions to the tracer \a position (used as an anchor) via \ref
+  QCPItemPosition::setParentAnchor.
+  
+  \note The tracer position is only automatically updated upon redraws. So when the data of the
+  graph changes and immediately afterwards (without a redraw) the position coordinates of the
+  tracer are retrieved, they will not reflect the updated data of the graph. In this case \ref
+  updatePosition must be called manually, prior to reading the tracer coordinates.

+  \brief A bracket for referencing/highlighting certain parts in the plot.
+
+  \image html QCPItemBracket.png "Bracket example. Blue dotted circles are anchors, solid blue discs are positions."
+
+  It has two positions, \a left and \a right, which define the span of the bracket. If \a left is
+  actually farther to the left than \a right, the bracket is opened to the bottom, as shown in the
+  example image.
+  
+  The bracket supports multiple styles via \ref setStyle. The length, i.e. how far the bracket
+  stretches away from the embraced span, can be controlled with \ref setLength.
+  
+  \image html QCPItemBracket-length.png
+  <center>Demonstrating the effect of different values for \ref setLength, for styles \ref
+  bsCalligraphic and \ref bsSquare. Anchors and positions are displayed for reference.</center>
+  
+  It provides an anchor \a center, to allow connection of other items, e.g. an arrow (QCPItemLine
+  or QCPItemCurve) or a text label (QCPItemText), to the bracket.

+/*! \class QCPDataContainer
+  \brief The generic data container for one-dimensional plottables
+
+  This class template provides a fast container for data storage of one-dimensional data. The data
+  type is specified as template parameter (called \a DataType in the following) and must provide
+  some methods as described in the \ref qcpdatacontainer-datatype "next section".
+
+  The data is stored in a sorted fashion, which allows very quick lookups by the sorted key as well
+  as retrieval of ranges (see \ref findBegin, \ref findEnd, \ref keyRange) using binary search. The
+  container uses a preallocation and a postallocation scheme, such that appending and prepending
+  data (with respect to the sort key) is very fast and minimizes reallocations. If data is added
+  which needs to be inserted between existing keys, the merge usually can be done quickly too,
+  using the fact that existing data is always sorted. The user can further improve performance by
+  specifying that added data is already itself sorted by key, if he can guarantee that this is the
+  case (see for example \ref add(const QVector<DataType> &data, bool alreadySorted)).
+
+  The data can be accessed with the provided const iterators (\ref constBegin, \ref constEnd). If
+  it is necessary to alter existing data in-place, the non-const iterators can be used (\ref begin,
+  \ref end). Changing data members that are not the sort key (for most data types called \a key) is
+  safe from the container's perspective.
+
+  Great care must be taken however if the sort key is modified through the non-const iterators. For
+  performance reasons, the iterators don't automatically cause a re-sorting upon their
+  manipulation. It is thus the responsibility of the user to leave the container in a sorted state
+  when finished with the data manipulation, before calling any other methods on the container. A
+  complete re-sort (e.g. after finishing all sort key manipulation) can be done by calling \ref
+  sort. Failing to do so can not be detected by the container efficiently and will cause both
+  rendering artifacts and potential data loss.
+
+  Implementing one-dimensional plottables that make use of a \ref QCPDataContainer<T> is usually
+  done by subclassing from \ref QCPAbstractPlottable1D "QCPAbstractPlottable1D<T>", which
+  introduces an according \a mDataContainer member and some convenience methods.
+
+  \section qcpdatacontainer-datatype Requirements for the DataType template parameter
+
+  The template parameter <tt>DataType</tt> is the type of the stored data points. It must be
+  trivially copyable and have the following public methods, preferably inline:
+
+  \li <tt>double sortKey() const</tt>\n Returns the member variable of this data point that is the
+  sort key, defining the ordering in the container. Often this variable is simply called \a key.
+
+  \li <tt>static DataType fromSortKey(double sortKey)</tt>\n Returns a new instance of the data
+  type initialized with its sort key set to \a sortKey.
+
+  \li <tt>static bool sortKeyIsMainKey()</tt>\n Returns true if the sort key is equal to the main
+  key (see method \c mainKey below). For most plottables this is the case. It is not the case for
+  example for \ref QCPCurve, which uses \a t as sort key and \a key as main key. This is the reason
+  why QCPCurve unlike QCPGraph can display parametric curves with loops.
+
+  \li <tt>double mainKey() const</tt>\n Returns the variable of this data point considered the main
+  key. This is commonly the variable that is used as the coordinate of this data point on the key
+  axis of the plottable. This method is used for example when determining the automatic axis
+  rescaling of key axes (\ref QCPAxis::rescale).
+
+  \li <tt>double mainValue() const</tt>\n Returns the variable of this data point considered the
+  main value. This is commonly the variable that is used as the coordinate of this data point on
+  the value axis of the plottable.
+
+  \li <tt>QCPRange valueRange() const</tt>\n Returns the range this data point spans in the value
+  axis coordinate. If the data is single-valued (e.g. QCPGraphData), this is simply a range with
+  both lower and upper set to the main data point value. However if the data points can represent
+  multiple values at once (e.g QCPFinancialData with its \a high, \a low, \a open and \a close
+  values at each \a key) this method should return the range those values span. This method is used
+  for example when determining the automatic axis rescaling of value axes (\ref
+  QCPAxis::rescale).

+/*! \class QCPPlottableInterface1D
+  \brief Defines an abstract interface for one-dimensional plottables
+
+  This class contains only pure virtual methods which define a common interface to the data
+  of one-dimensional plottables.
+
+  For example, it is implemented by the template class \ref QCPAbstractPlottable1D (the preferred
+  base class for one-dimensional plottables). So if you use that template class as base class of
+  your one-dimensional plottable, you won't have to care about implementing the 1d interface
+  yourself.
+
+  If your plottable doesn't derive from \ref QCPAbstractPlottable1D but still wants to provide a 1d
+  interface (e.g. like \ref QCPErrorBars does), you should inherit from both \ref
+  QCPAbstractPlottable and \ref QCPPlottableInterface1D and accordingly reimplement the pure
+  virtual methods of the 1d interface, matching your data container. Also, reimplement \ref
+  QCPAbstractPlottable::interface1D to return the \c this pointer.
+
+  If you have a \ref QCPAbstractPlottable pointer, you can check whether it implements this
+  interface by calling \ref QCPAbstractPlottable::interface1D and testing it for a non-zero return
+  value. If it indeed implements this interface, you may use it to access the plottable's data
+  without needing to know the exact type of the plottable or its data point type.

+
+/*! \fn virtual QCPDataSelection QCPPlottableInterface1D::selectTestRect(const QRectF &rect, bool onlySelectable) const = 0;
+  
+  Returns a data selection containing all the data points of this plottable which are contained (or
+  hit by) \a rect. This is used mainly in the selection rect interaction for data selection (\ref
+  dataselection "data selection mechanism").
+  
+  If \a onlySelectable is true, an empty QCPDataSelection is returned if this plottable is not
+  selectable (i.e. if \ref QCPAbstractPlottable::setSelectable is \ref QCP::stNone).
+  
+  \note \a rect must be a normalized rect (positive or zero width and height). This is especially
+  important when using the rect of \ref QCPSelectionRect::accepted, which is not necessarily
+  normalized. Use <tt>QRect::normalized()</tt> when passing a rect which might not be normalized.

+/*! \fn virtual QPointF QCPPlottableInterface1D::dataPixelPosition(int index) const = 0
+
+  Returns the pixel position on the widget surface at which the data point at the given \a index

+
+  Usually this corresponds to the point of \ref dataMainKey/\ref dataMainValue, in pixel
+  coordinates. However, depending on the plottable, this might be a different apparent position
+  than just a coord-to-pixel transform of those values. For example, \ref QCPBars apparent data

+/*! \class QCPAbstractPlottable1D
+  \brief A template base class for plottables with one-dimensional data
+
+  This template class derives from \ref QCPAbstractPlottable and from the abstract interface \ref
+  QCPPlottableInterface1D. It serves as a base class for all one-dimensional data (i.e. data with
+  one key dimension), such as \ref QCPGraph and QCPCurve.
+
+  The template parameter \a DataType is the type of the data points of this plottable (e.g. \ref
+  QCPGraphData or \ref QCPCurveData). The main purpose of this base class is to provide the member
+  \a mDataContainer (a shared pointer to a \ref QCPDataContainer "QCPDataContainer<DataType>") and
+  implement the according virtual methods of the \ref QCPPlottableInterface1D, such that most
+  subclassed plottables don't need to worry about this anymore.
+
+  Further, it provides a convenience method for retrieving selected/unselected data segments via
+  \ref getDataSegments. This is useful when subclasses implement their \ref draw method and need to
+  draw selected segments with a different pen/brush than unselected segments (also see \ref
+  QCPSelectionDecorator).
+
+  This class implements basic functionality of \ref QCPAbstractPlottable::selectTest and \ref
+  QCPPlottableInterface1D::selectTestRect, assuming point-like data points, based on the 1D data
+  interface. In spite of that, most plottable subclasses will want to reimplement those methods
+  again, to provide a more accurate hit test based on their specific data visualization geometry.

-  \brief The abstract base class for paint buffers, which define the rendering backend
-
-  This abstract base class defines the basic interface that a paint buffer needs to provide in
-  order to be usable by QCustomPlot.
-
-  A paint buffer manages both a surface to draw onto, and the matching paint device. The size of
-  the surface can be changed via \ref setSize. External classes (\ref QCustomPlot and \ref
-  QCPLayer) request a painter via \ref startPainting and then perform the draw calls. Once the
-  painting is complete, \ref donePainting is called, so the paint buffer implementation can do
-  clean up if necessary. Before rendering a frame, each paint buffer is usually filled with a color
-  using \ref clear (usually the color is \c Qt::transparent), to remove the contents of the
-  previous frame.
-
-  The simplest paint buffer implementation is \ref QCPPaintBufferPixmap which allows regular
-  software rendering via the raster engine. Hardware accelerated rendering via pixel buffers and
-  frame buffer objects is provided by \ref QCPPaintBufferGlPbuffer and \ref QCPPaintBufferGlFbo.
-  They are used automatically if \ref QCustomPlot::setOpenGl is enabled.

-/*! \class QCPLayer
-  \brief A layer that may contain objects, to control the rendering order
-
-  The Layering system of QCustomPlot is the mechanism to control the rendering order of the
-  elements inside the plot.
-
-  It is based on the two classes QCPLayer and QCPLayerable. QCustomPlot holds an ordered list of
-  one or more instances of QCPLayer (see QCustomPlot::addLayer, QCustomPlot::layer,
-  QCustomPlot::moveLayer, etc.). When replotting, QCustomPlot goes through the list of layers
-  bottom to top and successively draws the layerables of the layers into the paint buffer(s).
-
-  A QCPLayer contains an ordered list of QCPLayerable instances. QCPLayerable is an abstract base
-  class from which almost all visible objects derive, like axes, grids, graphs, items, etc.
-
-  \section qcplayer-defaultlayers Default layers
-
-  Initially, QCustomPlot has six layers: "background", "grid", "main", "axes", "legend" and
-  "overlay" (in that order). On top is the "overlay" layer, which only contains the QCustomPlot's
-  selection rect (\ref QCustomPlot::selectionRect). The next two layers "axes" and "legend" contain
-  the default axes and legend, so they will be drawn above plottables. In the middle, there is the
-  "main" layer. It is initially empty and set as the current layer (see
-  QCustomPlot::setCurrentLayer). This means, all new plottables, items etc. are created on this
-  layer by default. Then comes the "grid" layer which contains the QCPGrid instances (which belong
-  tightly to QCPAxis, see \ref QCPAxis::grid). The Axis rect background shall be drawn behind
-  everything else, thus the default QCPAxisRect instance is placed on the "background" layer. Of
-  course, the layer affiliation of the individual objects can be changed as required (\ref
-  QCPLayerable::setLayer).
-
-  \section qcplayer-ordering Controlling the rendering order via layers
-
-  Controlling the ordering of layerables in the plot is easy: Create a new layer in the position
-  you want the layerable to be in, e.g. above "main", with \ref QCustomPlot::addLayer. Then set the
-  current layer with \ref QCustomPlot::setCurrentLayer to that new layer and finally create the
-  objects normally. They will be placed on the new layer automatically, due to the current layer
-  setting. Alternatively you could have also ignored the current layer setting and just moved the
-  objects with \ref QCPLayerable::setLayer to the desired layer after creating them.
-
-  It is also possible to move whole layers. For example, If you want the grid to be shown in front
-  of all plottables/items on the "main" layer, just move it above "main" with
-  QCustomPlot::moveLayer.
-
-  The rendering order within one layer is simply by order of creation or insertion. The item
-  created last (or added last to the layer), is drawn on top of all other objects on that layer.
-
-  When a layer is deleted, the objects on it are not deleted with it, but fall on the layer below
-  the deleted layer, see QCustomPlot::removeLayer.
-
-  \section qcplayer-buffering Replotting only a specific layer
-
-  If the layer mode (\ref setMode) is set to \ref lmBuffered, you can replot only this specific
-  layer by calling \ref replot. In certain situations this can provide better replot performance,
-  compared with a full replot of all layers. Upon creation of a new layer, the layer mode is
-  initialized to \ref lmLogical. The only layer that is set to \ref lmBuffered in a new \ref
-  QCustomPlot instance is the "overlay" layer, containing the selection rect.

-  
-  This function applies the default antialiasing setting to the specified \a painter, using the
-  function \ref applyAntialiasingHint. It is the antialiasing state the painter is put in, when
-  \ref draw is called on the layerable. If the layerable has multiple entities whose antialiasing
-  setting may be specified individually, this function should set the antialiasing state of the
-  most prominent entity. In this case however, the \ref draw function usually calls the specialized
-  versions of this function before drawing each entity, effectively overriding the setting of the
-  default antialiasing hint.
-  
-  <b>First example:</b> QCPGraph has multiple entities that have an antialiasing setting: The graph
-  line, fills and scatters. Those can be configured via QCPGraph::setAntialiased,
-  QCPGraph::setAntialiasedFill and QCPGraph::setAntialiasedScatters. Consequently, there isn't only
-  the QCPGraph::applyDefaultAntialiasingHint function (which corresponds to the graph line's
-  antialiasing), but specialized ones like QCPGraph::applyFillAntialiasingHint and
-  QCPGraph::applyScattersAntialiasingHint. So before drawing one of those entities, QCPGraph::draw
-  calls the respective specialized applyAntialiasingHint function.
-  
-  <b>Second example:</b> QCPItemLine consists only of a line so there is only one antialiasing
-  setting which can be controlled with QCPItemLine::setAntialiased. (This function is inherited by
-  all layerables. The specialized functions, as seen on QCPGraph, must be added explicitly to the
-  respective layerable subclass.) Consequently it only has the normal
-  QCPItemLine::applyDefaultAntialiasingHint. The \ref QCPItemLine::draw function doesn't need to
-  care about setting any antialiasing states, because the default antialiasing hint is already set

-  This function is used to decide whether a click hits a layerable object or not.
-
-  \a pos is a point in pixel coordinates on the QCustomPlot surface. This function returns the
-  shortest pixel distance of this point to the object. If the object is either invisible or the
-  distance couldn't be determined, -1.0 is returned. Further, if \a onlySelectable is true and the
-  object is not selectable, -1.0 is returned, too.
-
-  If the object is represented not by single lines but by an area like a \ref QCPItemText or the
-  bars of a \ref QCPBars plottable, a click inside the area should also be considered a hit. In
-  these cases this function thus returns a constant value greater zero but still below the parent
-  plot's selection tolerance. (typically the selectionTolerance multiplied by 0.99).
-  
-  Providing a constant value for area objects allows selecting line objects even when they are
-  obscured by such area objects, by clicking close to the lines (i.e. closer than
-  0.99*selectionTolerance).
-  
-  The actual setting of the selection state is not done by this function. This is handled by the
-  parent QCustomPlot when the mouseReleaseEvent occurs, and the finally selected object is notified
-  via the \ref selectEvent/\ref deselectEvent methods.
-  
-  \a details is an optional output parameter. Every layerable subclass may place any information
-  in \a details. This information will be passed to \ref selectEvent when the parent QCustomPlot
-  decides on the basis of this selectTest call, that the object was successfully selected. The
-  subsequent call to \ref selectEvent will carry the \a details. This is useful for multi-part
-  objects (like QCPAxis). This way, a possibly complex calculation to decide which part was clicked
-  is only done once in \ref selectTest. The result (i.e. the actually clicked part) can then be
-  placed in \a details. So in the subsequent \ref selectEvent, the decision which part was
-  selected doesn't have to be done a second time for a single selection operation.
-  
-  You may pass 0 as \a details to indicate that you are not interested in those selection details.

-  \a event is the mouse event that caused the selection. \a additive indicates, whether the user
-  was holding the multi-select-modifier while performing the selection (see \ref
-  QCustomPlot::setMultiSelectModifier). if \a additive is true, the selection state must be toggled
-  (i.e. become selected when unselected and unselected when selected).
-

-/*! \class QCPDataRange
-  \brief Describes a data range given by begin and end index
-  
-  QCPDataRange holds two integers describing the begin (\ref setBegin) and end (\ref setEnd) index
-  of a contiguous set of data points. The end index points to the data point above the last data point that's part of
-  the data range, similarly to the nomenclature used in standard iterators.
-  
-  Data Ranges are not bound to a certain plottable, thus they can be freely exchanged, created and
-  modified. If a non-contiguous data set shall be described, the class \ref QCPDataSelection is
-  used, which holds and manages multiple instances of \ref QCPDataRange. In most situations, \ref
-  QCPDataSelection is thus used.
-  
-  Both \ref QCPDataRange and \ref QCPDataSelection offer convenience methods to work with them,
-  e.g. \ref bounded, \ref expanded, \ref intersects, \ref intersection, \ref adjusted, \ref
-  contains. Further, addition and subtraction operators (defined in \ref QCPDataSelection) can be
-  used to join/subtract data ranges and data selections (or mixtures), to retrieve a corresponding
-  \ref QCPDataSelection.
-  
-  %QCustomPlot's \ref dataselection "data selection mechanism" is based on \ref QCPDataSelection and
-  QCPDataRange.
-  
-  \note Do not confuse \ref QCPDataRange with \ref QCPRange. A \ref QCPRange describes an interval
-  in floating point plot coordinates, e.g. the current axis range.

-/*! \class QCPDataSelection
-  \brief Describes a data set by holding multiple QCPDataRange instances
-  
-  QCPDataSelection manages multiple instances of QCPDataRange in order to represent any (possibly
-  disjoint) set of data selection.
-  
-  The data selection can be modified with addition and subtraction operators which take
-  QCPDataSelection and QCPDataRange instances, as well as methods such as \ref addDataRange and
-  \ref clear. Read access is provided by \ref dataRange, \ref dataRanges, \ref dataRangeCount, etc.
-  
-  The method \ref simplify is used to join directly adjacent or even overlapping QCPDataRange
-  instances. QCPDataSelection automatically simplifies when using the addition/subtraction
-  operators. The only case when \ref simplify is left to the user, is when calling \ref
-  addDataRange, with the parameter \a simplify explicitly set to false. This is useful if many data
-  ranges will be added to the selection successively and the overhead for simplifying after each
-  iteration shall be avoided. In this case, you should make sure to call \ref simplify after
-  completing the operation.
-  
-  Use \ref enforceType to bring the data selection into a state complying with the constraints for
-  selections defined in \ref QCP::SelectionType.
-  
-  %QCustomPlot's \ref dataselection "data selection mechanism" is based on QCPDataSelection and

-/*! \class QCPMarginGroup
-  \brief A margin group allows synchronization of margin sides if working with multiple layout elements.
-  
-  QCPMarginGroup allows you to tie a margin side of two or more layout elements together, such that
-  they will all have the same size, based on the largest required margin in the group.
-  
-  \n
-  \image html QCPMarginGroup.png "Demonstration of QCPMarginGroup"
-  \n
-  
-  In certain situations it is desirable that margins at specific sides are synchronized across
-  layout elements. For example, if one QCPAxisRect is below another one in a grid layout, it will
-  provide a cleaner look to the user if the left and right margins of the two axis rects are of the
-  same size. The left axis of the top axis rect will then be at the same horizontal position as the
-  left axis of the lower axis rect, making them appear aligned. The same applies for the right
-  axes. This is what QCPMarginGroup makes possible.
-  
-  To add/remove a specific side of a layout element to/from a margin group, use the \ref
-  QCPLayoutElement::setMarginGroup method. To completely break apart the margin group, either call
-  \ref clear, or just delete the margin group.
-  
-  \section QCPMarginGroup-example Example
-  
-  First create a margin group:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpmargingroup-creation-1
-  Then set this group on the layout element sides:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpmargingroup-creation-2
-  Here, we've used the first two axis rects of the plot and synchronized their left margins with
-  each other and their right margins with each other.

-/*! \class QCPLayoutElement
-  \brief The abstract base class for all objects that form \ref thelayoutsystem "the layout system".
-  
-  This is an abstract base class. As such, it can't be instantiated directly, rather use one of its subclasses.
-  
-  A Layout element is a rectangular object which can be placed in layouts. It has an outer rect
-  (QCPLayoutElement::outerRect) and an inner rect (\ref QCPLayoutElement::rect). The difference
-  between outer and inner rect is called its margin. The margin can either be set to automatic or
-  manual (\ref setAutoMargins) on a per-side basis. If a side is set to manual, that margin can be
-  set explicitly with \ref setMargins and will stay fixed at that value. If it's set to automatic,
-  the layout element subclass will control the value itself (via \ref calculateAutoMargin).
-  
-  Layout elements can be placed in layouts (base class QCPLayout) like QCPLayoutGrid. The top level
-  layout is reachable via \ref QCustomPlot::plotLayout, and is a \ref QCPLayoutGrid. Since \ref
-  QCPLayout itself derives from \ref QCPLayoutElement, layouts can be nested.
-  
-  Thus in QCustomPlot one can divide layout elements into two categories: The ones that are
-  invisible by themselves, because they don't draw anything. Their only purpose is to manage the
-  position and size of other layout elements. This category of layout elements usually use
-  QCPLayout as base class. Then there is the category of layout elements which actually draw
-  something. For example, QCPAxisRect, QCPLegend and QCPTextElement are of this category. This does
-  not necessarily mean that the latter category can't have child layout elements. QCPLegend for
-  instance, actually derives from QCPLayoutGrid and the individual legend items are child layout
-  elements in the grid layout.

-  area is used to display peripheral graphics while the main content is in the inner rect. This is

-/*! \class QCPLayout
-  \brief The abstract base class for layouts
-  
-  This is an abstract base class for layout elements whose main purpose is to define the position
-  and size of other child layout elements. In most cases, layouts don't draw anything themselves
-  (but there are exceptions to this, e.g. QCPLegend).
-  
-  QCPLayout derives from QCPLayoutElement, and thus can itself be nested in other layouts.
-  
-  QCPLayout introduces a common interface for accessing and manipulating the child elements. Those
-  functions are most notably \ref elementCount, \ref elementAt, \ref takeAt, \ref take, \ref
-  simplify, \ref removeAt, \ref remove and \ref clear. Individual subclasses may add more functions
-  to this interface which are more specialized to the form of the layout. For example, \ref
-  QCPLayoutGrid adds functions that take row and column indices to access cells of the layout grid
-  more conveniently.
-  
-  Since this is an abstract base class, you can't instantiate it directly. Rather use one of its
-  subclasses like QCPLayoutGrid or QCPLayoutInset.
-  
-  For a general introduction to the layout system, see the dedicated documentation page \ref
-  thelayoutsystem "The Layout System".

-/*! \class QCPLayoutGrid
-  \brief A layout that arranges child elements in a grid
-
-  Elements are laid out in a grid with configurable stretch factors (\ref setColumnStretchFactor,
-  \ref setRowStretchFactor) and spacing (\ref setColumnSpacing, \ref setRowSpacing).
-
-  Elements can be added to cells via \ref addElement. The grid is expanded if the specified row or
-  column doesn't exist yet. Whether a cell contains a valid layout element can be checked with \ref
-  hasElement, that element can be retrieved with \ref element. If rows and columns that only have
-  empty cells shall be removed, call \ref simplify. Removal of elements is either done by just
-  adding the element to a different layout or by using the QCPLayout interface \ref take or \ref
-  remove.
-
-  If you use \ref addElement(QCPLayoutElement*) without explicit parameters for \a row and \a
-  column, the grid layout will choose the position according to the current \ref setFillOrder and
-  the wrapping (\ref setWrap).
-
-  Row and column insertion can be performed with \ref insertRow and \ref insertColumn.

-  
-  For every ending a line-like item has, an instance of this class exists. For example, QCPItemLine
-  has two endings which can be set with QCPItemLine::setHead and QCPItemLine::setTail.
- 
-  The styles themselves are defined via the enum QCPLineEnding::EndingStyle. Most decorations can
-  be modified regarding width and length, see \ref setWidth and \ref setLength. The direction of
-  the ending decoration (e.g. direction an arrow is pointing) is controlled by the line-like item.
-  For example, when both endings of a QCPItemLine are set to be arrows, they will point to opposite
-  directions, e.g. "outward". This can be changed by \ref setInverted, which would make the
-  respective arrow point inward.
-  
-  Note that due to the overloaded QCPLineEnding constructor, you may directly specify a
-  QCPLineEnding::EndingStyle where actually a QCPLineEnding is expected, e.g.

-/*! \class QCPAxisTicker
-  \brief The base class tick generator used by QCPAxis to create tick positions and tick labels
-  
-  Each QCPAxis has an internal QCPAxisTicker (or a subclass) in order to generate tick positions
-  and tick labels for the current axis range. The ticker of an axis can be set via \ref
-  QCPAxis::setTicker. Since that method takes a <tt>QSharedPointer<QCPAxisTicker></tt>, multiple
-  axes can share the same ticker instance.
-  
-  This base class generates normal tick coordinates and numeric labels for linear axes. It picks a
-  reasonable tick step (the separation between ticks) which results in readable tick labels. The
-  number of ticks that should be approximately generated can be set via \ref setTickCount.
-  Depending on the current tick step strategy (\ref setTickStepStrategy), the algorithm either
-  sacrifices readability to better match the specified tick count (\ref
-  QCPAxisTicker::tssMeetTickCount) or relaxes the tick count in favor of better tick steps (\ref
-  QCPAxisTicker::tssReadability), which is the default.
-  
-  The following more specialized axis ticker subclasses are available, see details in the
-  respective class documentation:

-  \section axisticker-subclassing Creating own axis tickers
-  
-  Creating own axis tickers can be achieved very easily by sublassing QCPAxisTicker and
-  reimplementing some or all of the available virtual methods.
-
-  In the simplest case you might wish to just generate different tick steps than the other tickers,
-  so you only reimplement the method \ref getTickStep. If you additionally want control over the
-  string that will be shown as tick label, reimplement \ref getTickLabel.
-  
-  If you wish to have complete control, you can generate the tick vectors and tick label vectors
-  yourself by reimplementing \ref createTickVector and \ref createLabelVector. The default
-  implementations use the previously mentioned virtual methods \ref getTickStep and \ref
-  getTickLabel, but your reimplementations don't necessarily need to do so. For example in the case
-  of unequal tick steps, the method \ref getTickStep loses its usefulness and can be ignored.
-  
-  The sub tick count between major ticks can be controlled with \ref getSubTickCount. Full sub tick
-  placement control is obtained by reimplementing \ref createSubTickVector.
-  
-  See the documentation of all these virtual methods in QCPAxisTicker for detailed information
-  about the parameters and expected return values.

-/*! \class QCPAxisTickerDateTime
-  \brief Specialized axis ticker for calendar dates and times as axis ticks
-  
-  \image html axisticker-datetime.png
-  
-  This QCPAxisTicker subclass generates ticks that correspond to real calendar dates and times. The
-  plot axis coordinate is interpreted as Unix Time, so seconds since Epoch (January 1, 1970, 00:00
-  UTC). This is also used for example by QDateTime in the <tt>toTime_t()/setTime_t()</tt> methods
-  with a precision of one second. Since Qt 4.7, millisecond accuracy can be obtained from QDateTime
-  by using <tt>QDateTime::fromMSecsSinceEpoch()/1000.0</tt>. The static methods \ref dateTimeToKey
-  and \ref keyToDateTime conveniently perform this conversion achieving a precision of one
-  millisecond on all Qt versions.
-  
-  The format of the date/time display in the tick labels is controlled with \ref setDateTimeFormat.
-  If a different time spec (time zone) shall be used, see \ref setDateTimeSpec.
-  
-  This ticker produces unequal tick spacing in order to provide intuitive date and time-of-day
-  ticks. For example, if the axis range spans a few years such that there is one tick per year,
-  ticks will be positioned on 1. January of every year. This is intuitive but, due to leap years,
-  will result in slightly unequal tick intervals (visually unnoticeable). The same can be seen in
-  the image above: even though the number of days varies month by month, this ticker generates
-  ticks on the same day of each month.
-  
-  If you would like to change the date/time that is used as a (mathematical) starting date for the
-  ticks, use the \ref setTickOrigin(const QDateTime &origin) method overload, which takes a
-  QDateTime. If you pass 15. July, 9:45 to this method, the yearly ticks will end up on 15. July at
-  9:45 of every year.
-  
-  The ticker can be created and assigned to an axis like this:
-  \snippet documentation/doc-image-generator/mainwindow.cpp axistickerdatetime-creation
-  
-  \note If you rather wish to display relative times in terms of days, hours, minutes, seconds and
-  milliseconds, and are not interested in the intricacies of real calendar dates with months and
-  (leap) years, have a look at QCPAxisTickerTime instead.

-/*! \class QCPAxisTickerTime
-  \brief Specialized axis ticker for time spans in units of milliseconds to days
-  
-  \image html axisticker-time.png
-  
-  This QCPAxisTicker subclass generates ticks that corresponds to time intervals.
-  
-  The format of the time display in the tick labels is controlled with \ref setTimeFormat and \ref
-  setFieldWidth. The time coordinate is in the unit of seconds with respect to the time coordinate
-  zero. Unlike with QCPAxisTickerDateTime, the ticks don't correspond to a specific calendar date
-  and time.
-  
-  The time can be displayed in milliseconds, seconds, minutes, hours and days. Depending on the
-  largest available unit in the format specified with \ref setTimeFormat, any time spans above will
-  be carried in that largest unit. So for example if the format string is "%m:%s" and a tick at
-  coordinate value 7815 (being 2 hours, 10 minutes and 15 seconds) is created, the resulting tick
-  label will show "130:15" (130 minutes, 15 seconds). If the format string is "%h:%m:%s", the hour
-  unit will be used and the label will thus be "02:10:15". Negative times with respect to the axis
-  zero will carry a leading minus sign.
-  
-  The ticker can be created and assigned to an axis like this:
-  \snippet documentation/doc-image-generator/mainwindow.cpp axistickertime-creation
-  
-  Here is an example of a time axis providing time information in days, hours and minutes. Due to
-  the axis range spanning a few days and the wanted tick count (\ref setTickCount), the ticker
-  decided to use tick steps of 12 hours:
-  
-  \image html axisticker-time2.png
-  
-  The format string for this example is

-/*! \class QCPAxisTickerLog
-  \brief Specialized axis ticker suited for logarithmic axes
-  
-  \image html axisticker-log.png
-  
-  This QCPAxisTicker subclass generates ticks with unequal tick intervals suited for logarithmic
-  axis scales. The ticks are placed at powers of the specified log base (\ref setLogBase).
-  
-  Especially in the case of a log base equal to 10 (the default), it might be desirable to have
-  tick labels in the form of powers of ten without mantissa display. To achieve this, set the
-  number precision (\ref QCPAxis::setNumberPrecision) to zero and the number format (\ref
-  QCPAxis::setNumberFormat) to scientific (exponential) display with beautifully typeset decimal
-  powers, so a format string of <tt>"eb"</tt>. This will result in the following axis tick labels:
-

-  
-  \a formatCode is a string of one, two or three characters. The first character is identical to
-  the normal format code used by Qt. In short, this means: 'e'/'E' scientific format, 'f' fixed
-  format, 'g'/'G' scientific or fixed, whichever is shorter.
-  
-  The second and third characters are optional and specific to QCustomPlot:\n
-  If the first char was 'e' or 'g', numbers are/might be displayed in the scientific format, e.g.
-  "5.5e9", which is ugly in a plot. So when the second char of \a formatCode is set to 'b' (for
-  "beautiful"), those exponential numbers are formatted in a more natural way, i.e. "5.5
-  [multiplication sign] 10 [superscript] 9". By default, the multiplication sign is a centered dot.
-  If instead a cross should be shown (as is usual in the USA), the third char of \a formatCode can
-  be set to 'c'. The inserted multiplication signs are the UTF-8 characters 215 (0xD7) for the
-  cross and 183 (0xB7) for the dot.
-  
-  Examples for \a formatCode:
-  \li \c g normal format code behaviour. If number is small, fixed format is used, if number is large,
-  normal scientific format is used
-  \li \c gb If number is small, fixed format is used, if number is large, scientific format is used with
-  beautifully typeset decimal powers and a dot as multiplication sign
-  \li \c ebc All numbers are in scientific format with beautifully typeset decimal power and a cross as
-  multiplication sign
-  \li \c fb illegal format code, since fixed format doesn't support (or need) beautifully typeset decimal
-  powers. Format code will be reduced to 'f'.
-  \li \c hello illegal format code, since first char is not 'e', 'E', 'f', 'g' or 'G'. Current format
-  code will not be changed.

-/*! \class QCPScatterStyle
-  \brief Represents the visual appearance of scatter points
-  
-  This class holds information about shape, color and size of scatter points. In plottables like
-  QCPGraph it is used to store how scatter points shall be drawn. For example, \ref
-  QCPGraph::setScatterStyle takes a QCPScatterStyle instance.
-  
-  A scatter style consists of a shape (\ref setShape), a line color (\ref setPen) and possibly a
-  fill (\ref setBrush), if the shape provides a fillable area. Further, the size of the shape can
-  be controlled with \ref setSize.
-
-  \section QCPScatterStyle-defining Specifying a scatter style
-  
-  You can set all these configurations either by calling the respective functions on an instance:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpscatterstyle-creation-1
-  
-  Or you can use one of the various constructors that take different parameter combinations, making
-  it easy to specify a scatter style in a single call, like so:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpscatterstyle-creation-2
-  
-  \section QCPScatterStyle-undefinedpen Leaving the color/pen up to the plottable
-  
-  There are two constructors which leave the pen undefined: \ref QCPScatterStyle() and \ref
-  QCPScatterStyle(ScatterShape shape, double size). If those constructors are used, a call to \ref
-  isPenDefined will return false. It leads to scatter points that inherit the pen from the
-  plottable that uses the scatter style. Thus, if such a scatter style is passed to QCPGraph, the line
-  color of the graph (\ref QCPGraph::setPen) will be used by the scatter points. This makes
-  it very convenient to set up typical scatter settings:
-  
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpscatterstyle-shortcreation
-
-  Notice that it wasn't even necessary to explicitly call a QCPScatterStyle constructor. This works
-  because QCPScatterStyle provides a constructor that can transform a \ref ScatterShape directly
-  into a QCPScatterStyle instance (that's the \ref QCPScatterStyle(ScatterShape shape, double size)
-  constructor with a default for \a size). In those cases, C++ allows directly supplying a \ref
-  ScatterShape, where actually a QCPScatterStyle is expected.
-  
-  \section QCPScatterStyle-custompath-and-pixmap Custom shapes and pixmaps
-  
-  QCPScatterStyle supports drawing custom shapes and arbitrary pixmaps as scatter points.
-
-  For custom shapes, you can provide a QPainterPath with the desired shape to the \ref
-  setCustomPath function or call the constructor that takes a painter path. The scatter shape will
-  automatically be set to \ref ssCustom.
-  
-  For pixmaps, you call \ref setPixmap with the desired QPixmap. Alternatively you can use the
-  constructor that takes a QPixmap. The scatter shape will automatically be set to \ref ssPixmap.
-  Note that \ref setSize does not influence the appearance of the pixmap.

-  
-  The pen is undefined if a constructor is called that does not carry \a pen as parameter. Those
-  are \ref QCPScatterStyle() and \ref QCPScatterStyle(ScatterShape shape, double size). If the pen
-  is undefined, the pen of the respective plottable will be used for drawing scatters.

-/*! \class QCPSelectionDecorator
-  \brief Controls how a plottable's data selection is drawn
-  
-  Each \ref QCPAbstractPlottable instance has one \ref QCPSelectionDecorator (accessible via \ref
-  QCPAbstractPlottable::selectionDecorator) and uses it when drawing selected segments of its data.
-  
-  The selection decorator controls both pen (\ref setPen) and brush (\ref setBrush), as well as the
-  scatter style (\ref setScatterStyle) if the plottable draws scatters. Since a \ref
-  QCPScatterStyle is itself composed of different properties such as color shape and size, the
-  decorator allows specifying exactly which of those properties shall be used for the selected data
-  point, via \ref setUsedScatterProperties.
-  
-  A \ref QCPSelectionDecorator subclass instance can be passed to a plottable via \ref
-  QCPAbstractPlottable::setSelectionDecorator, allowing greater customizability of the appearance
-  of selected segments.
-  
-  Use \ref copyFrom to easily transfer the settings of one decorator to another one. This is
-  especially useful since plottables take ownership of the passed selection decorator, and thus the
-  same decorator instance can not be passed to multiple plottables.
-  
-  Selection decorators can also themselves perform drawing operations by reimplementing \ref
-  drawDecoration, which is called by the plottable's draw method. The base class \ref
-  QCPSelectionDecorator does not make use of this however. For example, \ref
-  QCPSelectionDecoratorBracket draws brackets around selected data segments.

-/*! \class QCPAbstractPlottable
-  \brief The abstract base class for all data representing objects in a plot.
-
-  It defines a very basic interface like name, pen, brush, visibility etc. Since this class is
-  abstract, it can't be instantiated. Use one of the subclasses or create a subclass yourself to
-  create new ways of displaying data (see "Creating own plottables" below). Plottables that display
-  one-dimensional data (i.e. data points have a single key dimension and one or multiple values at
-  each key) are based off of the template subclass \ref QCPAbstractPlottable1D, see details
-  there.
-  
-  All further specifics are in the subclasses, for example:
-  \li A normal graph with possibly a line and/or scatter points \ref QCPGraph
-  (typically created with \ref QCustomPlot::addGraph)
-  \li A parametric curve: \ref QCPCurve
-  \li A bar chart: \ref QCPBars
-  \li A statistical box plot: \ref QCPStatisticalBox
-  \li A color encoded two-dimensional map: \ref QCPColorMap
-  \li An OHLC/Candlestick chart: \ref QCPFinancial
-  
-  \section plottables-subclassing Creating own plottables
-  
-  Subclassing directly from QCPAbstractPlottable is only recommended if you wish to display
-  two-dimensional data like \ref QCPColorMap, i.e. two logical key dimensions and one (or more)
-  data dimensions. If you want to display data with only one logical key dimension, you should
-  rather derive from \ref QCPAbstractPlottable1D.
-  
-  If subclassing QCPAbstractPlottable directly, these are the pure virtual functions you must
-  implement:
-  \li \ref selectTest
-  \li \ref draw
-  \li \ref drawLegendIcon
-  \li \ref getKeyRange
-  \li \ref getValueRange
-  
-  See the documentation of those functions for what they need to do.
-  
-  For drawing your plot, you can use the \ref coordsToPixels functions to translate a point in plot
-  coordinates to pixel coordinates. This function is quite convenient, because it takes the
-  orientation of the key and value axes into account for you (x and y are swapped when the key axis
-  is vertical and the value axis horizontal). If you are worried about performance (i.e. you need
-  to translate many points in a loop like QCPGraph), you can directly use \ref
-  QCPAxis::coordToPixel. However, you must then take care about the orientation of the axis
-  yourself.
-  
-  Here are some important members you inherit from QCPAbstractPlottable:
-  <table>
-  <tr>
-    <td>QCustomPlot *\b mParentPlot</td>
-    <td>A pointer to the parent QCustomPlot instance. The parent plot is inferred from the axes that are passed in the constructor.</td>
-  </tr><tr>
-    <td>QString \b mName</td>
-    <td>The name of the plottable.</td>
-  </tr><tr>
-    <td>QPen \b mPen</td>
-    <td>The generic pen of the plottable. You should use this pen for the most prominent data representing lines in the plottable
-        (e.g QCPGraph uses this pen for its graph lines and scatters)</td>
-  </tr><tr>
-    <td>QBrush \b mBrush</td>
-    <td>The generic brush of the plottable. You should use this brush for the most prominent fillable structures in the plottable
-        (e.g. QCPGraph uses this brush to control filling under the graph)</td>
-  </tr><tr>
-    <td>QPointer<\ref QCPAxis> \b mKeyAxis, \b mValueAxis</td>
-    <td>The key and value axes this plottable is attached to. Call their QCPAxis::coordToPixel functions to translate coordinates
-        to pixels in either the key or value dimension. Make sure to check whether the pointer is null before using it. If one of
-        the axes is null, don't draw the plottable.</td>
-  </tr><tr>
-    <td>\ref QCPSelectionDecorator \b mSelectionDecorator</td>
-    <td>The currently set selection decorator which specifies how selected data of the plottable shall be drawn and decorated.
-        When drawing your data, you must consult this decorator for the appropriate pen/brush before drawing unselected/selected data segments.
-        Finally, you should call its \ref QCPSelectionDecorator::drawDecoration method at the end of your \ref draw implementation.</td>
-  </tr><tr>
-    <td>\ref QCP::SelectionType \b mSelectable</td>
-    <td>In which composition, if at all, this plottable's data may be selected. Enforcing this setting on the data selection is done
-        by QCPAbstractPlottable automatically.</td>
-  </tr><tr>
-    <td>\ref QCPDataSelection \b mSelection</td>

-/*! \class QCPItemAnchor
-  \brief An anchor of an item to which positions can be attached to.
-  
-  An item (QCPAbstractItem) may have one or more anchors. Unlike QCPItemPosition, an anchor doesn't
-  control anything on its item, but provides a way to tie other items via their positions to the
-  anchor.
-
-  For example, a QCPItemRect is defined by its positions \a topLeft and \a bottomRight.
-  Additionally it has various anchors like \a top, \a topRight or \a bottomLeft etc. So you can
-  attach the \a start (which is a QCPItemPosition) of a QCPItemLine to one of the anchors by
-  calling QCPItemPosition::setParentAnchor on \a start, passing the wanted anchor of the
-  QCPItemRect. This way the start of the line will now always follow the respective anchor location
-  on the rect item.
-  
-  Note that QCPItemPosition derives from QCPItemAnchor, so every position can also serve as an
-  anchor to other positions.
-  
-  To learn how to provide anchors in your own item subclasses, see the subclassing section of the
-  QCPAbstractItem documentation.

-/*! \class QCPItemPosition
-  \brief Manages the position of an item.
-  
-  Every item has at least one public QCPItemPosition member pointer which provides ways to position the
-  item on the QCustomPlot surface. Some items have multiple positions, for example QCPItemRect has two:
-  \a topLeft and \a bottomRight.
-
-  QCPItemPosition has a type (\ref PositionType) that can be set with \ref setType. This type
-  defines how coordinates passed to \ref setCoords are to be interpreted, e.g. as absolute pixel
-  coordinates, as plot coordinates of certain axes, etc. For more advanced plots it is also
-  possible to assign different types per X/Y coordinate of the position (see \ref setTypeX, \ref
-  setTypeY). This way an item could be positioned at a fixed pixel distance from the top in the Y
-  direction, while following a plot coordinate in the X direction.
-
-  A QCPItemPosition may have a parent QCPItemAnchor, see \ref setParentAnchor. This way you can tie
-  multiple items together. If the QCPItemPosition has a parent, its coordinates (\ref setCoords)
-  are considered to be absolute pixels in the reference frame of the parent anchor, where (0, 0)
-  means directly ontop of the parent anchor. For example, You could attach the \a start position of
-  a QCPItemLine to the \a bottom anchor of a QCPItemText to make the starting point of the line
-  always be centered under the text label, no matter where the text is moved to. For more advanced
-  plots, it is possible to assign different parent anchors per X/Y coordinate of the position, see
-  \ref setParentAnchorX, \ref setParentAnchorY. This way an item could follow another item in the X
-  direction but stay at a fixed position in the Y direction. Or even follow item A in X, and item B
-  in Y.
-
-  Note that every QCPItemPosition inherits from QCPItemAnchor and thus can itself be used as parent
-  anchor for other positions.
-
-  To set the apparent pixel position on the QCustomPlot surface directly, use \ref setPixelPosition. This
-  works no matter what type this QCPItemPosition is or what parent-child situation it is in, as \ref
-  setPixelPosition transforms the coordinates appropriately, to make the position appear at the specified
-  pixel values.

-/*! \class QCPAbstractItem
-  \brief The abstract base class for all items in a plot.
-  
-  In QCustomPlot, items are supplemental graphical elements that are neither plottables
-  (QCPAbstractPlottable) nor axes (QCPAxis). While plottables are always tied to two axes and thus
-  plot coordinates, items can also be placed in absolute coordinates independent of any axes. Each
-  specific item has at least one QCPItemPosition member which controls the positioning. Some items
-  are defined by more than one coordinate and thus have two or more QCPItemPosition members (For
-  example, QCPItemRect has \a topLeft and \a bottomRight).
-  
-  This abstract base class defines a very basic interface like visibility and clipping. Since this
-  class is abstract, it can't be instantiated. Use one of the subclasses or create a subclass
-  yourself to create new items.
-  
-  The built-in items are:
-  <table>
-  <tr><td>QCPItemLine</td><td>A line defined by a start and an end point. May have different ending styles on each side (e.g. arrows).</td></tr>
-  <tr><td>QCPItemStraightLine</td><td>A straight line defined by a start and a direction point. Unlike QCPItemLine, the straight line is infinitely long and has no endings.</td></tr>
-  <tr><td>QCPItemCurve</td><td>A curve defined by start, end and two intermediate control points. May have different ending styles on each side (e.g. arrows).</td></tr>
-  <tr><td>QCPItemRect</td><td>A rectangle</td></tr>
-  <tr><td>QCPItemEllipse</td><td>An ellipse</td></tr>
-  <tr><td>QCPItemPixmap</td><td>An arbitrary pixmap</td></tr>
-  <tr><td>QCPItemText</td><td>A text label</td></tr>
-  <tr><td>QCPItemBracket</td><td>A bracket which may be used to reference/highlight certain parts in the plot.</td></tr>
-  <tr><td>QCPItemTracer</td><td>An item that can be attached to a QCPGraph and sticks to its data points, given a key coordinate.</td></tr>
-  </table>
-  
-  \section items-clipping Clipping
-
-  Items are by default clipped to the main axis rect (they are only visible inside the axis rect).
-  To make an item visible outside that axis rect, disable clipping via \ref setClipToAxisRect
-  "setClipToAxisRect(false)".
-
-  On the other hand if you want the item to be clipped to a different axis rect, specify it via
-  \ref setClipAxisRect. This clipAxisRect property of an item is only used for clipping behaviour, and
-  in principle is independent of the coordinate axes the item might be tied to via its position
-  members (\ref QCPItemPosition::setAxes). However, it is common that the axis rect for clipping
-  also contains the axes used for the item positions.
-  
-  \section items-using Using items
-  
-  First you instantiate the item you want to use and add it to the plot:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-1
-  by default, the positions of the item are bound to the x- and y-Axis of the plot. So we can just
-  set the plot coordinates where the line should start/end:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-2
-  If we don't want the line to be positioned in plot coordinates but a different coordinate system,
-  e.g. absolute pixel positions on the QCustomPlot surface, we need to change the position type like this:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-3
-  Then we can set the coordinates, this time in pixels:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-4
-  and make the line visible on the entire QCustomPlot, by disabling clipping to the axis rect:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-5
-  
-  For more advanced plots, it is even possible to set different types and parent anchors per X/Y
-  coordinate of an item position, using for example \ref QCPItemPosition::setTypeX or \ref
-  QCPItemPosition::setParentAnchorX. For details, see the documentation of \ref QCPItemPosition.
-  
-  \section items-subclassing Creating own items
-  
-  To create an own item, you implement a subclass of QCPAbstractItem. These are the pure
-  virtual functions, you must implement:
-  \li \ref selectTest
-  \li \ref draw
-  
-  See the documentation of those functions for what they need to do.
-  
-  \subsection items-positioning Allowing the item to be positioned
-  
-  As mentioned, item positions are represented by QCPItemPosition members. Let's assume the new item shall
-  have only one point as its position (as opposed to two like a rect or multiple like a polygon). You then add
-  a public member of type QCPItemPosition like so:
-  
-  \code QCPItemPosition * const myPosition;\endcode
-  
-  the const makes sure the pointer itself can't be modified from the user of your new item (the QCPItemPosition
-  instance it points to, can be modified, of course).
-  The initialization of this pointer is made easy with the \ref createPosition function. Just assign
-  the return value of this function to each QCPItemPosition in the constructor of your item. \ref createPosition
-  takes a string which is the name of the position, typically this is identical to the variable name.
-  For example, the constructor of QCPItemExample could look like this:
-  
-  \code
-  QCPItemExample::QCPItemExample(QCustomPlot *parentPlot) :
-    QCPAbstractItem(parentPlot),
-    myPosition(createPosition("myPosition"))
-  {
-    // other constructor code
-  }
-  \endcode
-  
-  \subsection items-drawing The draw function
-  
-  To give your item a visual representation, reimplement the \ref draw function and use the passed
-  QCPPainter to draw the item. You can retrieve the item position in pixel coordinates from the
-  position member(s) via \ref QCPItemPosition::pixelPosition.
-
-  To optimize performance you should calculate a bounding rect first (don't forget to take the pen
-  width into account), check whether it intersects the \ref clipRect, and only draw the item at all
-  if this is the case.
-  
-  \subsection items-selection The selectTest function
-  
-  Your implementation of the \ref selectTest function may use the helpers \ref
-  QCPVector2D::distanceSquaredToLine and \ref rectDistance. With these, the implementation of the
-  selection test becomes significantly simpler for most items. See the documentation of \ref
-  selectTest for what the function parameters mean and what the function should return.
-  
-  \subsection anchors Providing anchors
-  
-  Providing anchors (QCPItemAnchor) starts off like adding a position. First you create a public
-  member, e.g.
-  
-  \code QCPItemAnchor * const bottom;\endcode
-
-  and create it in the constructor with the \ref createAnchor function, assigning it a name and an
-  anchor id (an integer enumerating all anchors on the item, you may create an own enum for this).
-  Since anchors can be placed anywhere, relative to the item's position(s), your item needs to
-  provide the position of every anchor with the reimplementation of the \ref anchorPixelPosition(int
-  anchorId) function.
-  
-  In essence the QCPItemAnchor is merely an intermediary that itself asks your item for the pixel
-  position when anything attached to the anchor needs to know the coordinates.

-  respective interaction is enabled, the user may drag axes ranges and zoom with the mouse wheel.
-  For details how to control which axes the user may drag/zoom and in what orientations, see \ref
-  QCPAxisRect::setRangeDrag, \ref QCPAxisRect::setRangeZoom, \ref QCPAxisRect::setRangeDragAxes,
-  \ref QCPAxisRect::setRangeZoomAxes.
-  
-  <b>Plottable data selection</b> is controlled by \ref QCP::iSelectPlottables. If \ref
-  QCP::iSelectPlottables is set, the user may select plottables (graphs, curves, bars,...) and
-  their data by clicking on them or in their vicinity (\ref setSelectionTolerance). Whether the
-  user can actually select a plottable and its data can further be restricted with the \ref
-  QCPAbstractPlottable::setSelectable method on the specific plottable. For details, see the
-  special page about the \ref dataselection "data selection mechanism". To retrieve a list of all
-  currently selected plottables, call \ref selectedPlottables. If you're only interested in
-  QCPGraphs, you may use the convenience function \ref selectedGraphs.
-  
-  <b>Item selection</b> is controlled by \ref QCP::iSelectItems. If \ref QCP::iSelectItems is set, the user
-  may select items (QCPItemLine, QCPItemText,...) by clicking on them or in their vicinity. To find
-  out whether a specific item is selected, call QCPAbstractItem::selected(). To retrieve a list of
-  all currently selected items, call \ref selectedItems.
-  
-  <b>Axis selection</b> is controlled with \ref QCP::iSelectAxes. If \ref QCP::iSelectAxes is set, the user
-  may select parts of the axes by clicking on them. What parts exactly (e.g. Axis base line, tick
-  labels, axis label) are selectable can be controlled via \ref QCPAxis::setSelectableParts for
-  each axis. To retrieve a list of all axes that currently contain selected parts, call \ref
-  selectedAxes. Which parts of an axis are selected, can be retrieved with QCPAxis::selectedParts().
-  
-  <b>Legend selection</b> is controlled with \ref QCP::iSelectLegend. If this is set, the user may
-  select the legend itself or individual items by clicking on them. What parts exactly are
-  selectable can be controlled via \ref QCPLegend::setSelectableParts. To find out whether the
-  legend or any of its child items are selected, check the value of QCPLegend::selectedParts. To
-  find out which child items are selected, call \ref QCPLegend::selectedItems.
-  
-  <b>All other selectable elements</b> The selection of all other selectable objects (e.g.
-  QCPTextElement, or your own layerable subclasses) is controlled with \ref QCP::iSelectOther. If set, the
-  user may select those objects by clicking on them. To find out which are currently selected, you
-  need to check their selected state explicitly.
-  
-  If the selection state has changed by user interaction, the \ref selectionChangedByUser signal is
-  emitted. Each selectable object additionally emits an individual selectionChanged signal whenever
-  their selection state has changed, i.e. not only by user interaction.
-

-  \warning This is still an experimental feature and its performance depends on the system that it

-  might cause context conflicts on some systems.
-  
-  This method allows to enable OpenGL plot rendering, for increased plotting performance of
-  graphically demanding plots (thick lines, translucent fills, etc.).
-
-  If \a enabled is set to true, QCustomPlot will try to initialize OpenGL and, if successful,
-  continue plotting with hardware acceleration. The parameter \a multisampling controls how many
-  samples will be used per pixel, it essentially controls the antialiasing quality. If \a
-  multisampling is set too high for the current graphics hardware, the maximum allowed value will
-  be used.
-
-  You can test whether switching to OpenGL rendering was successful by checking whether the
-  according getter \a QCustomPlot::openGl() returns true. If the OpenGL initialization fails,
-  rendering continues with the regular software rasterizer, and an according qDebug output is
-  generated.
-
-  If switching to OpenGL was successful, this method disables label caching (\ref setPlottingHint
-  "setPlottingHint(QCP::phCacheLabels, false)") and turns on QCustomPlot's antialiasing override
-  for all elements (\ref setAntialiasedElements "setAntialiasedElements(QCP::aeAll)"), leading to a
-  higher quality output. The antialiasing override allows for pixel-grid aligned drawing in the
-  OpenGL paint device. As stated before, in OpenGL rendering the actual antialiasing of the plot is
-  controlled with \a multisampling. If \a enabled is set to false, the antialiasing/label caching
-  settings are restored to what they were before OpenGL was enabled, if they weren't altered in the
-  meantime.
-
-  \note OpenGL support is only enabled if QCustomPlot is compiled with the macro \c QCUSTOMPLOT_USE_OPENGL
-  defined. This define must be set before including the QCustomPlot header both during compilation
-  of the QCustomPlot library as well as when compiling your application. It is best to just include
-  the line <tt>DEFINES += QCUSTOMPLOT_USE_OPENGL</tt> in the respective qmake project files.
-  \note If you are using a Qt version before 5.0, you must also add the module "opengl" to your \c
-  QT variable in the qmake project files. For Qt versions 5.0 and higher, QCustomPlot switches to a
-  newer OpenGL interface which is already in the "gui" module.

-
-  The parameter \a refreshPriority can be used to fine-tune the timing of the replot. For example

-  replot with this priority will only cause a single replot, avoiding redundant replots and
-  improving performance.

-/*! \class QCPColorGradient
-  \brief Defines a color gradient for use with e.g. \ref QCPColorMap
-  
-  This class describes a color gradient which can be used to encode data with color. For example,
-  QCPColorMap and QCPColorScale have \ref QCPColorMap::setGradient "setGradient" methods which
-  take an instance of this class. Colors are set with \ref setColorStopAt(double position, const QColor &color)
-  with a \a position from 0 to 1. In between these defined color positions, the
-  color will be interpolated linearly either in RGB or HSV space, see \ref setColorInterpolation.
-
-  Alternatively, load one of the preset color gradients shown in the image below, with \ref
-  loadPreset, or by directly specifying the preset in the constructor.
-  
-  Apart from red, green and blue components, the gradient also interpolates the alpha values of the
-  configured color stops. This allows to display some portions of the data range as transparent in
-  the plot.
-  
-  \image html QCPColorGradient.png
-  
-  The \ref QCPColorGradient(GradientPreset preset) constructor allows directly converting a \ref
-  GradientPreset to a QCPColorGradient. This means that you can directly pass \ref GradientPreset
-  to all the \a setGradient methods, e.g.:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorgradient-setgradient
-  
-  The total number of levels used in the gradient can be set with \ref setLevelCount. Whether the
-  color gradient shall be applied periodically (wrapping around) to data values that lie outside
-  the data range specified on the plottable instance can be controlled with \ref setPeriodic.

-/*! \class QCPAxisRect
-  \brief Holds multiple axes and arranges them in a rectangular shape.
-  
-  This class represents an axis rect, a rectangular area that is bounded on all sides with an
-  arbitrary number of axes.
-  
-  Initially QCustomPlot has one axis rect, accessible via QCustomPlot::axisRect(). However, the
-  layout system allows to have multiple axis rects, e.g. arranged in a grid layout
-  (QCustomPlot::plotLayout).
-  
-  By default, QCPAxisRect comes with four axes, at bottom, top, left and right. They can be
-  accessed via \ref axis by providing the respective axis type (\ref QCPAxis::AxisType) and index.
-  If you need all axes in the axis rect, use \ref axes. The top and right axes are set to be
-  invisible initially (QCPAxis::setVisible). To add more axes to a side, use \ref addAxis or \ref
-  addAxes. To remove an axis, use \ref removeAxis.
-  
-  The axis rect layerable itself only draws a background pixmap or color, if specified (\ref
-  setBackground). It is placed on the "background" layer initially (see \ref QCPLayer for an
-  explanation of the QCustomPlot layer system). The axes that are held by the axis rect can be
-  placed on other layers, independently of the axis rect.
-  
-  Every axis rect has a child layout of type \ref QCPLayoutInset. It is accessible via \ref
-  insetLayout and can be used to have other layout elements (or even other layouts with multiple
-  elements) hovering inside the axis rect.
-  
-  If an axis rect is clicked and dragged, it processes this by moving certain axis ranges. The
-  behaviour can be controlled with \ref setRangeDrag and \ref setRangeDragAxes. If the mouse wheel
-  is scrolled while the cursor is on the axis rect, certain axes are scaled. This is controllable
-  via \ref setRangeZoom, \ref setRangeZoomAxes and \ref setRangeZoomFactor. These interactions are
-  only enabled if \ref QCustomPlot::setInteractions contains \ref QCP::iRangeDrag and \ref
-  QCP::iRangeZoom.

-  \brief A legend item representing a plottable with an icon and the plottable name.
-  
-  This is the standard legend item for plottables. It displays an icon of the plottable next to the

-  QCPAbstractPlottable::drawLegendIcon), and tries to give an intuitive symbol for the plottable.
-  For example, the QCPGraph draws a centered horizontal line and/or a single scatter point in the
-  middle.
-  
-  Legend items of this type are always associated with one plottable (retrievable via the
-  plottable() function and settable with the constructor). You may change the font of the plottable
-  name with \ref setFont. Icon padding and border pen is taken from the parent QCPLegend, see \ref
-  QCPLegend::setIconBorderPen and \ref QCPLegend::setIconTextPadding.
-
-  The function \ref QCPAbstractPlottable::addToLegend/\ref QCPAbstractPlottable::removeFromLegend

-/*! \class QCPLegend
-  \brief Manages a legend inside a QCustomPlot.
-
-  A legend is a small box somewhere in the plot which lists plottables with their name and icon.
-
-  A legend is populated with legend items by calling \ref QCPAbstractPlottable::addToLegend on the
-  plottable, for which a legend item shall be created. In the case of the main legend (\ref
-  QCustomPlot::legend), simply adding plottables to the plot while \ref
-  QCustomPlot::setAutoAddPlottableToLegend is set to true (the default) creates corresponding
-  legend items. The legend item associated with a certain plottable can be removed with \ref
-  QCPAbstractPlottable::removeFromLegend. However, QCPLegend also offers an interface to add and
-  manipulate legend items directly: \ref item, \ref itemWithPlottable, \ref itemCount, \ref
-  addItem, \ref removeItem, etc.
-
-  Since \ref QCPLegend derives from \ref QCPLayoutGrid, it can be placed in any position a \ref
-  QCPLayoutElement may be positioned. The legend items are themselves \ref QCPLayoutElement
-  "QCPLayoutElements" which are placed in the grid layout of the legend. \ref QCPLegend only adds
-  an interface specialized for handling child elements of type \ref QCPAbstractLegendItem, as
-  mentioned above. In principle, any other layout elements may also be added to a legend via the
-  normal \ref QCPLayoutGrid interface. See the special page about \link thelayoutsystem The Layout
-  System\endlink for examples on how to add other elements to the legend and move it outside the axis
-  rect.
-
-  Use the methods \ref setFillOrder and \ref setWrap inherited from \ref QCPLayoutGrid to control
-  in which order (column first or row first) the legend is filled up when calling \ref addItem, and
-  at which column or row wrapping occurs.
-
-  By default, every QCustomPlot has one legend (\ref QCustomPlot::legend) which is placed in the
-  inset layout of the main axis rect (\ref QCPAxisRect::insetLayout). To move the legend to another
-  position inside the axis rect, use the methods of the \ref QCPLayoutInset. To move the legend
-  outside of the axis rect, place it anywhere else with the \ref QCPLayout/\ref QCPLayoutElement
-  interface.

-/*! \class QCPColorScale
-  \brief A color scale for use with color coding data such as QCPColorMap
-  
-  This layout element can be placed on the plot to correlate a color gradient with data values. It
-  is usually used in combination with one or multiple \ref QCPColorMap "QCPColorMaps".
-
-  \image html QCPColorScale.png
-  
-  The color scale can be either horizontal or vertical, as shown in the image above. The
-  orientation and the side where the numbers appear is controlled with \ref setType.
-  
-  Use \ref QCPColorMap::setColorScale to connect a color map with a color scale. Once they are
-  connected, they share their gradient, data range and data scale type (\ref setGradient, \ref
-  setDataRange, \ref setDataScaleType). Multiple color maps may be associated with a single color
-  scale, to make them all synchronize these properties.
-  
-  To have finer control over the number display and axis behaviour, you can directly access the
-  \ref axis. See the documentation of QCPAxis for details about configuring axes. For example, if
-  you want to change the number of automatically generated ticks, call
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorscale-tickcount
-  
-  Placing a color scale next to the main axis rect works like with any other layout element:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorscale-creation
-  In this case we have placed it to the right of the default axis rect, so it wasn't necessary to
-  call \ref setType, since \ref QCPAxis::atRight is already the default. The text next to the color
-  scale can be set with \ref setLabel.
-  
-  For optimum appearance (like in the image above), it may be desirable to line up the axis rect and
-  the borders of the color scale. Use a \ref QCPMarginGroup to achieve this:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorscale-margingroup
-  
-  Color scales are initialized with a non-zero minimum top and bottom margin (\ref
-  setMinimumMargins), because vertical color scales are most common and the minimum top/bottom
-  margin makes sure it keeps some distance to the top/bottom widget border. So if you change to a
-  horizontal color scale by setting \ref setType to \ref QCPAxis::atBottom or \ref QCPAxis::atTop, you
-  might want to also change the minimum margins accordingly, e.g. <tt>setMinimumMargins(QMargins(6, 0, 6, 0))</tt>.

-
-/*! \fn QCPAxis *QCPColorScale::axis() const
-  
-  Returns the internal \ref QCPAxis instance of this color scale. You can access it to alter the
-  appearance and behaviour of the axis. \ref QCPColorScale duplicates some properties in its
-  interface for convenience. Those are \ref setDataRange (\ref QCPAxis::setRange), \ref
-  setDataScaleType (\ref QCPAxis::setScaleType), and the method \ref setLabel (\ref
-  QCPAxis::setLabel). As they each are connected, it does not matter whether you use the method on
-  the QCPColorScale or on its QCPAxis.
-  
-  If the type of the color scale is changed with \ref setType, the axis returned by this method
-  will change, too, to either the left, right, bottom or top axis, depending on which type was set.

-/*! \class QCPGraph
-  \brief A plottable representing a graph in a plot.
-
-  \image html QCPGraph.png
-  
-  Usually you create new graphs by calling QCustomPlot::addGraph. The resulting instance can be
-  accessed via QCustomPlot::graph.
-
-  To plot data, assign it with the \ref setData or \ref addData functions. Alternatively, you can
-  also access and modify the data via the \ref data method, which returns a pointer to the internal
-  \ref QCPGraphDataContainer.
-  
-  Graphs are used to display single-valued data. Single-valued means that there should only be one
-  data point per unique key coordinate. In other words, the graph can't have \a loops. If you do
-  want to plot non-single-valued curves, rather use the QCPCurve plottable.
-  
-  Gaps in the graph line can be created by adding data points with NaN as value
-  (<tt>qQNaN()</tt> or <tt>std::numeric_limits<double>::quiet_NaN()</tt>) in between the two data points that shall be
-  separated.
-  
-  \section qcpgraph-appearance Changing the appearance
-  
-  The appearance of the graph is mainly determined by the line style, scatter style, brush and pen
-  of the graph (\ref setLineStyle, \ref setScatterStyle, \ref setBrush, \ref setPen).
-  
-  \subsection filling Filling under or between graphs
-  
-  QCPGraph knows two types of fills: Normal graph fills towards the zero-value-line parallel to
-  the key axis of the graph, and fills between two graphs, called channel fills. To enable a fill,
-  just set a brush with \ref setBrush which is neither Qt::NoBrush nor fully transparent.
-  
-  By default, a normal fill towards the zero-value-line will be drawn. To set up a channel fill
-  between this graph and another one, call \ref setChannelFillGraph with the other graph as
-  parameter.

-  sampling technique can drastically improve the replot performance for graphs with a larger number
-  of points (e.g. above 10,000), without notably changing the appearance of the graph.
-  
-  By default, adaptive sampling is enabled. Even if enabled, QCustomPlot decides whether adaptive
-  sampling shall actually be used on a per-graph basis. So leaving adaptive sampling enabled has no
-  disadvantage in almost all cases.
-  
-  \image html adaptive-sampling-line.png "A line plot of 500,000 points without and with adaptive sampling"
-  
-  As can be seen, line plots experience no visual degradation from adaptive sampling. Outliers are
-  reproduced reliably, as well as the overall shape of the data set. The replot time reduces
-  dramatically though. This allows QCustomPlot to display large amounts of data in realtime.
-  
-  \image html adaptive-sampling-scatter.png "A scatter plot of 100,000 points without and with adaptive sampling"
-  
-  Care must be taken when using high-density scatter plots in combination with adaptive sampling.
-  The adaptive sampling algorithm treats scatter plots more carefully than line plots which still
-  gives a significant reduction of replot times, but not quite as much as for line plots. This is
-  because scatter plots inherently need more data points to be preserved in order to still resemble
-  the original, non-adaptive-sampling plot. As shown above, the results still aren't quite
-  identical, as banding occurs for the outer data points. This is in fact intentional, such that
-  the boundaries of the data cloud stay visible to the viewer. How strong the banding appears,
-  depends on the point density, i.e. the number of points in the plot.
-  
-  For some situations with scatter plots it might thus be desirable to manually turn adaptive
-  sampling off. For example, when saving the plot to disk. This can be achieved by setting \a
-  enabled to false before issuing a command like \ref QCustomPlot::savePng, and setting \a enabled
-  back to true afterwards.

-/*! \class QCPCurve
-  \brief A plottable representing a parametric curve in a plot.
-  
-  \image html QCPCurve.png
-  
-  Unlike QCPGraph, plottables of this type may have multiple points with the same key coordinate,
-  so their visual representation can have \a loops. This is realized by introducing a third
-  coordinate \a t, which defines the order of the points described by the other two coordinates \a
-  x and \a y.
-
-  To plot data, assign it with the \ref setData or \ref addData functions. Alternatively, you can
-  also access and modify the curve's data via the \ref data method, which returns a pointer to the
-  internal \ref QCPCurveDataContainer.
-  
-  Gaps in the curve can be created by adding data points with NaN as key and value
-  (<tt>qQNaN()</tt> or <tt>std::numeric_limits<double>::quiet_NaN()</tt>) in between the two data points that shall be
-  separated.
-  
-  \section qcpcurve-appearance Changing the appearance
-  
-  The appearance of the curve is determined by the pen and the brush (\ref setPen, \ref setBrush).
-  
-  \section qcpcurve-usage Usage
-  
-  Like all data representing objects in QCustomPlot, the QCPCurve is a plottable
-  (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
-  (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
-  
-  Usually, you first create an instance:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcurve-creation-1
-  which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot instance takes
-  ownership of the plottable, so do not delete it manually but use QCustomPlot::removePlottable() instead.
-  The newly created plottable can be modified, e.g.:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcurve-creation-2

-  regular \ref setData or \ref addData methods.

-  printed to the debug output (qDebug), the construction is not aborted, though.
-  
-  The created QCPCurve is automatically registered with the QCustomPlot instance inferred from \a
-  keyAxis. This QCustomPlot instance takes ownership of the QCPCurve, so do not delete it manually

-  This function is part of the curve optimization algorithm of \ref getCurveLines.
-  
-  In situations where a single segment skips over multiple regions it might become necessary to add
-  extra points at the corners of region 5 (see \ref getRegion) such that the optimized segment
-  doesn't unintentionally cut through the visible area of the axis rect and create plot artifacts.
-  This method provides these points that must be added, assuming the original segment doesn't
-  start, end, or traverse region 5. (Corner points where region 5 is traversed are calculated by
-  \ref getTraverseCornerPoints.)
-  
-  For example, consider a segment which directly goes from region 4 to 2 but originally is far out
-  to the top left such that it doesn't cross region 5. Naively optimizing these points by
-  projecting them on the top and left borders of region 5 will create a segment that surely crosses
-  5, creating a visual artifact in the plot. This method prevents this by providing extra points at
-  the top left corner, making the optimized curve correctly pass from region 4 to 1 to 2 without
-  traversing 5.

-  This function is part of the curve optimization algorithm of \ref getCurveLines.

-  This method assumes that the \ref getTraverse test has returned true, so the segment definitely
-  traverses the visible region 5 when going from \a prevRegion to \a currentRegion.
-  
-  In certain situations it is not sufficient to merely generate the entry and exit points of the
-  segment into/out of region 5, as \ref getTraverse provides. It may happen that a single segment, in
-  addition to traversing region 5, skips another region outside of region 5, which makes it
-  necessary to add an optimized corner point there (very similar to the job \ref
-  getOptimizedCornerPoints does for segments that are completely in outside regions and don't
-  traverse 5).
-  
-  As an example, consider a segment going from region 1 to region 6, traversing the lower left
-  corner of region 5. In this configuration, the segment additionally crosses the border between
-  region 1 and 2 before entering region 5. This makes it necessary to add an additional point in
-  the top left corner, before adding the optimized traverse points. So in this case, the output
-  parameter \a beforeTraverse will contain the top left corner point, and \a afterTraverse will be
-  empty.
-  
-  In some cases, such as when going from region 1 to 9, it may even be necessary to add additional
-  corner points before and after the traverse. Then both \a beforeTraverse and \a afterTraverse
-  return the respective corner points.

-  \brief Groups multiple QCPBars together so they appear side by side
-  
-  \image html QCPBarsGroup.png
-  
-  When showing multiple QCPBars in one plot which have bars at identical keys, it may be desirable
-  to have them appearing next to each other at each key. This is what adding the respective QCPBars
-  plottables to a QCPBarsGroup achieves. (An alternative approach is to stack them on top of each
-  other, see \ref QCPBars::moveAbove.)
-  
-  \section qcpbarsgroup-usage Usage
-  
-  To add a QCPBars plottable to the group, create a new group and then add the respective bars
-  intances:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpbarsgroup-creation
-  Alternatively to appending to the group like shown above, you can also set the group on the
-  QCPBars plottable via \ref QCPBars::setBarsGroup.
-  
-  The spacing between the bars can be configured via \ref setSpacingType and \ref setSpacing. The
-  bars in this group appear in the plot in the order they were appended. To insert a bars plottable
-  at a certain index position, or to reposition a bars plottable which is already in the group, use
-  \ref insert.
-  
-  To remove specific bars from the group, use either \ref remove or call \ref
-  QCPBars::setBarsGroup "QCPBars::setBarsGroup(0)" on the respective bars plottable.
-  
-  To clear the entire group, call \ref clear, or simply delete the group.

-  
-  \section qcpbars-appearance Changing the appearance

-  The appearance of the bars is determined by the pen and the brush (\ref setPen, \ref setBrush).
-  The width of the individual bars can be controlled with \ref setWidthType and \ref setWidth.
-  
-  Bar charts are stackable. This means, two QCPBars plottables can be placed on top of each other
-  (see \ref QCPBars::moveAbove). So when two bars are at the same key position, they will appear
-  stacked.
-  
-  If you would like to group multiple QCPBars plottables together so they appear side by side as

-  
-  \section qcpbars-usage Usage
-  
-  Like all data representing objects in QCustomPlot, the QCPBars is a plottable
-  (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
-  (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
-  
-  Usually, you first create an instance:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpbars-creation-1
-  which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot instance takes
-  ownership of the plottable, so do not delete it manually but use QCustomPlot::removePlottable() instead.
-  The newly created plottable can be modified, e.g.:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpbars-creation-2

-/*! \class QCPStatisticalBox
-  \brief A plottable representing a single statistical box in a plot.
-
-  \image html QCPStatisticalBox.png
-  
-  To plot data, assign it with the \ref setData or \ref addData functions. Alternatively, you can
-  also access and modify the data via the \ref data method, which returns a pointer to the internal
-  \ref QCPStatisticalBoxDataContainer.
-  
-  Additionally each data point can itself have a list of outliers, drawn as scatter points at the
-  key coordinate of the respective statistical box data point. They can either be set by using the
-  respective \ref addData(double,double,double,double,double,double,const QVector<double>&)
-  "addData" method or accessing the individual data points through \ref data, and setting the
-  <tt>QVector<double> outliers</tt> of the data points directly.
-  
-  \section qcpstatisticalbox-appearance Changing the appearance
-  
-  The appearance of each data point box, ranging from the lower to the upper quartile, is
-  controlled via \ref setPen and \ref setBrush. You may change the width of the boxes with \ref
-  setWidth in plot coordinates.
-
-  Each data point's visual representation also consists of two whiskers. Whiskers are the lines
-  which reach from the upper quartile to the maximum, and from the lower quartile to the minimum.
-  The appearance of the whiskers can be modified with: \ref setWhiskerPen, \ref setWhiskerBarPen,
-  \ref setWhiskerWidth. The whisker width is the width of the bar perpendicular to the whisker at
-  the top (for maximum) and bottom (for minimum). If the whisker pen is changed, make sure to set
-  the \c capStyle to \c Qt::FlatCap. Otherwise the backbone line might exceed the whisker bars by a
-  few pixels due to the pen cap being not perfectly flat.
-  
-  The median indicator line inside the box has its own pen, \ref setMedianPen.
-  
-  The outlier data points are drawn as normal scatter points. Their look can be controlled with
-  \ref setOutlierStyle
-  
-  \section qcpstatisticalbox-usage Usage
-  
-  Like all data representing objects in QCustomPlot, the QCPStatisticalBox is a plottable
-  (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
-  (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
-  
-  Usually, you first create an instance:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpstatisticalbox-creation-1
-  which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot instance takes
-  ownership of the plottable, so do not delete it manually but use QCustomPlot::removePlottable() instead.
-  The newly created plottable can be modified, e.g.:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpstatisticalbox-creation-2

-  convenient and faster than using the regular \ref setData or \ref addData methods.

-  message is printed to the debug output (qDebug), the construction is not aborted, though.

-/*! \class QCPColorMapData
-  \brief Holds the two-dimensional data of a QCPColorMap plottable.
-  
-  This class is a data storage for \ref QCPColorMap. It holds a two-dimensional array, which \ref
-  QCPColorMap then displays as a 2D image in the plot, where the array values are represented by a
-  color, depending on the value.
-  
-  The size of the array can be controlled via \ref setSize (or \ref setKeySize, \ref setValueSize).
-  Which plot coordinates these cells correspond to can be configured with \ref setRange (or \ref
-  setKeyRange, \ref setValueRange).
-  
-  The data cells can be accessed in two ways: They can be directly addressed by an integer index
-  with \ref setCell. This is the fastest method. Alternatively, they can be addressed by their plot
-  coordinate with \ref setData. plot coordinate to cell index transformations and vice versa are
-  provided by the functions \ref coordToCell and \ref cellToCoord.
-  
-  A \ref QCPColorMapData also holds an on-demand two-dimensional array of alpha values which (if
-  allocated) has the same size as the data map. It can be accessed via \ref setAlpha, \ref
-  fillAlpha and \ref clearAlpha. The memory for the alpha map is only allocated if needed, i.e. on
-  the first call of \ref setAlpha. \ref clearAlpha restores full opacity and frees the alpha map.
-  
-  This class also buffers the minimum and maximum values that are in the data set, to provide
-  QCPColorMap::rescaleDataRange with the necessary information quickly. Setting a cell to a value
-  that is greater than the current maximum increases this maximum to the new value. However,
-  setting the cell that currently holds the maximum value to a smaller value doesn't decrease the
-  maximum again, because finding the true new maximum would require going through the entire data
-  array, which might be time consuming. The same holds for the data minimum. This functionality is
-  given by \ref recalculateDataBounds, such that you can decide when it is sensible to find the
-  true current minimum and maximum. The method QCPColorMap::rescaleDataRange offers a convenience
-  parameter \a recalculateDataBounds which may be set to true to automatically call \ref
-  recalculateDataBounds internally.

-/*! \class QCPColorMap
-  \brief A plottable representing a two-dimensional color map in a plot.
-
-  \image html QCPColorMap.png
-  
-  The data is stored in the class \ref QCPColorMapData, which can be accessed via the data()
-  method.
-  
-  A color map has three dimensions to represent a data point: The \a key dimension, the \a value
-  dimension and the \a data dimension. As with other plottables such as graphs, \a key and \a value
-  correspond to two orthogonal axes on the QCustomPlot surface that you specify in the QCPColorMap
-  constructor. The \a data dimension however is encoded as the color of the point at (\a key, \a
-  value).
-
-  Set the number of points (or \a cells) in the key/value dimension via \ref
-  QCPColorMapData::setSize. The plot coordinate range over which these points will be displayed is
-  specified via \ref QCPColorMapData::setRange. The first cell will be centered on the lower range
-  boundary and the last cell will be centered on the upper range boundary. The data can be set by
-  either accessing the cells directly with QCPColorMapData::setCell or by addressing the cells via
-  their plot coordinates with \ref QCPColorMapData::setData. If possible, you should prefer
-  setCell, since it doesn't need to do any coordinate transformation and thus performs a bit
-  better.
-  
-  The cell with index (0, 0) is at the bottom left, if the color map uses normal (i.e. not reversed)
-  key and value axes.
-  
-  To show the user which colors correspond to which \a data values, a \ref QCPColorScale is
-  typically placed to the right of the axis rect. See the documentation there for details on how to
-  add and use a color scale.
-  
-  \section qcpcolormap-appearance Changing the appearance
-  
-  The central part of the appearance is the color gradient, which can be specified via \ref
-  setGradient. See the documentation of \ref QCPColorGradient for details on configuring a color
-  gradient.
-  
-  The \a data range that is mapped to the colors of the gradient can be specified with \ref
-  setDataRange. To make the data range encompass the whole data set minimum to maximum, call \ref
-  rescaleDataRange.
-  
-  \section qcpcolormap-transparency Transparency
-  
-  Transparency in color maps can be achieved by two mechanisms. On one hand, you can specify alpha
-  values for color stops of the \ref QCPColorGradient, via the regular QColor interface. This will
-  cause the color map data which gets mapped to colors around those color stops to appear with the
-  accordingly interpolated transparency.
-  
-  On the other hand you can also directly apply an alpha value to each cell independent of its
-  data, by using the alpha map feature of \ref QCPColorMapData. The relevant methods are \ref
-  QCPColorMapData::setAlpha, QCPColorMapData::fillAlpha and \ref QCPColorMapData::clearAlpha().
-  
-  The two transparencies will be joined together in the plot and otherwise not interfere with each
-  other. They are mixed in a multiplicative matter, so an alpha of e.g. 50% (128/255) in both modes
-  simultaneously, will result in a total transparency of 25% (64/255).
-  
-  \section qcpcolormap-usage Usage
-  
-  Like all data representing objects in QCustomPlot, the QCPColorMap is a plottable
-  (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
-  (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
-  
-  Usually, you first create an instance:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolormap-creation-1
-  which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot instance takes
-  ownership of the plottable, so do not delete it manually but use QCustomPlot::removePlottable() instead.
-  The newly created plottable can be modified, e.g.:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolormap-creation-2
-  
-  \note The QCPColorMap always displays the data at equal key/value intervals, even if the key or
-  value axis is set to a logarithmic scaling. If you want to use QCPColorMap with logarithmic axes,
-  you shouldn't use the \ref QCPColorMapData::setData method as it uses a linear transformation to
-  determine the cell index. Rather directly access the cell index with \ref
-  QCPColorMapData::setCell.

-/*! \class QCPFinancial
-  \brief A plottable representing a financial stock chart
-
-  \image html QCPFinancial.png
-
-  This plottable represents time series data binned to certain intervals, mainly used for stock
-  charts. The two common representations OHLC (Open-High-Low-Close) bars and Candlesticks can be
-  set via \ref setChartStyle.
-
-  The data is passed via \ref setData as a set of open/high/low/close values at certain keys
-  (typically times). This means the data must be already binned appropriately. If data is only
-  available as a series of values (e.g. \a price against \a time), you can use the static
-  convenience function \ref timeSeriesToOhlc to generate binned OHLC-data which can then be passed
-  to \ref setData.
-
-  The width of the OHLC bars/candlesticks can be controlled with \ref setWidth and \ref
-  setWidthType. A typical choice is to set the width type to \ref wtPlotCoords (the default) and
-  the width to (or slightly less than) one time bin interval width.
-
-  \section qcpfinancial-appearance Changing the appearance
-
-  Charts can be either single- or two-colored (\ref setTwoColored). If set to be single-colored,
-  lines are drawn with the plottable's pen (\ref setPen) and fills with the brush (\ref setBrush).
-
-  If set to two-colored, positive changes of the value during an interval (\a close >= \a open) are
-  represented with a different pen and brush than negative changes (\a close < \a open). These can
-  be configured with \ref setPenPositive, \ref setPenNegative, \ref setBrushPositive, and \ref
-  setBrushNegative. In two-colored mode, the normal plottable pen/brush is ignored. Upon selection
-  however, the normal selected pen/brush (provided by the \ref selectionDecorator) is used,
-  irrespective of whether the chart is single- or two-colored.
-
-  \section qcpfinancial-usage Usage
-
-  Like all data representing objects in QCustomPlot, the QCPFinancial is a plottable
-  (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
-  (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
-
-  Usually, you first create an instance:
-
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpfinancial-creation-1
-  which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot
-  instance takes ownership of the plottable, so do not delete it manually but use
-  QCustomPlot::removePlottable() instead. The newly created plottable can be modified, e.g.:
-
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpfinancial-creation-2
-  Here we have used the static helper method \ref timeSeriesToOhlc, to turn a time-price data
-  series into a 24-hour binned open-high-low-close data series as QCPFinancial uses.

-  Returns a pointer to the internal data storage of type \ref QCPFinancialDataContainer. You may

-  regular \ref setData or \ref addData methods, in certain situations.

-  printed to the debug output (qDebug), the construction is not aborted, though.

-  The created QCPFinancial is automatically registered with the QCustomPlot instance inferred from \a

-  \brief A plottable that adds a set of error bars to other plottables.
-
-  \image html QCPErrorBars.png
-
-  The \ref QCPErrorBars plottable can be attached to other one-dimensional plottables (e.g. \ref
-  QCPGraph, \ref QCPCurve, \ref QCPBars, etc.) and equips them with error bars.
-
-  Use \ref setDataPlottable to define for which plottable the \ref QCPErrorBars shall display the
-  error bars. The orientation of the error bars can be controlled with \ref setErrorType.
-
-  By using \ref setData, you can supply the actual error data, either as symmetric error or
-  plus/minus asymmetric errors. \ref QCPErrorBars only stores the error data. The absolute
-  key/value position of each error bar will be adopted from the configured data plottable. The
-  error data of the \ref QCPErrorBars are associated one-to-one via their index to the data points
-  of the data plottable. You can directly access and manipulate the error bar data via \ref data.
-
-  Set either of the plus/minus errors to NaN (<tt>qQNaN()</tt> or
-  <tt>std::numeric_limits<double>::quiet_NaN()</tt>) to not show the respective error bar on the data point at
-  that index.
-
-  \section qcperrorbars-appearance Changing the appearance
-
-  The appearance of the error bars is defined by the pen (\ref setPen), and the width of the
-  whiskers (\ref setWhiskerWidth). Further, the error bar backbones may leave a gap around the data
-  point center to prevent that error bars are drawn too close to or even through scatter points.
-  This gap size can be controlled via \ref setSymbolGap.

-/*! \class QCPItemTracer
-  \brief Item that sticks to QCPGraph data points
-
-  \image html QCPItemTracer.png "Tracer example. Blue dotted circles are anchors, solid blue discs are positions."
-
-  The tracer can be connected with a QCPGraph via \ref setGraph. Then it will automatically adopt
-  the coordinate axes of the graph and update its \a position to be on the graph's data. This means
-  the key stays controllable via \ref setGraphKey, but the value will follow the graph data. If a
-  QCPGraph is connected, note that setting the coordinates of the tracer item directly via \a
-  position will have no effect because they will be overriden in the next redraw (this is when the
-  coordinate update happens).
-  
-  If the specified key in \ref setGraphKey is outside the key bounds of the graph, the tracer will
-  stay at the corresponding end of the graph.
-  
-  With \ref setInterpolating you may specify whether the tracer may only stay exactly on data
-  points or whether it interpolates data points linearly, if given a key that lies between two data
-  points of the graph.
-  
-  The tracer has different visual styles, see \ref setStyle. It is also possible to make the tracer
-  have no own visual appearance (set the style to \ref tsNone), and just connect other item
-  positions to the tracer \a position (used as an anchor) via \ref
-  QCPItemPosition::setParentAnchor.
-  
-  \note The tracer position is only automatically updated upon redraws. So when the data of the
-  graph changes and immediately afterwards (without a redraw) the position coordinates of the
-  tracer are retrieved, they will not reflect the updated data of the graph. In this case \ref
-  updatePosition must be called manually, prior to reading the tracer coordinates.

+  \brief The abstract base class for paint buffers, which define the rendering backend
+
+  This abstract base class defines the basic interface that a paint buffer needs to provide in
+  order to be usable by QCustomPlot.
+
+  A paint buffer manages both a surface to draw onto, and the matching paint device. The size of
+  the surface can be changed via \ref setSize. External classes (\ref QCustomPlot and \ref
+  QCPLayer) request a painter via \ref startPainting and then perform the draw calls. Once the
+  painting is complete, \ref donePainting is called, so the paint buffer implementation can do
+  clean up if necessary. Before rendering a frame, each paint buffer is usually filled with a color
+  using \ref clear (usually the color is \c Qt::transparent), to remove the contents of the
+  previous frame.
+
+  The simplest paint buffer implementation is \ref QCPPaintBufferPixmap which allows regular
+  software rendering via the raster engine. Hardware accelerated rendering via pixel buffers and
+  frame buffer objects is provided by \ref QCPPaintBufferGlPbuffer and \ref QCPPaintBufferGlFbo.

+/*! \class QCPLayer
+  \brief A layer that may contain objects, to control the rendering order
+
+  The Layering system of QCustomPlot is the mechanism to control the rendering order of the
+  elements inside the plot.
+
+  It is based on the two classes QCPLayer and QCPLayerable. QCustomPlot holds an ordered list of
+  one or more instances of QCPLayer (see QCustomPlot::addLayer, QCustomPlot::layer,
+  QCustomPlot::moveLayer, etc.). When replotting, QCustomPlot goes through the list of layers
+  bottom to top and successively draws the layerables of the layers into the paint buffer(s).
+
+  A QCPLayer contains an ordered list of QCPLayerable instances. QCPLayerable is an abstract base
+  class from which almost all visible objects derive, like axes, grids, graphs, items, etc.
+
+  \section qcplayer-defaultlayers Default layers
+
+  Initially, QCustomPlot has six layers: "background", "grid", "main", "axes", "legend" and
+  "overlay" (in that order). On top is the "overlay" layer, which only contains the QCustomPlot's
+  selection rect (\ref QCustomPlot::selectionRect). The next two layers "axes" and "legend" contain
+  the default axes and legend, so they will be drawn above plottables. In the middle, there is the
+  "main" layer. It is initially empty and set as the current layer (see
+  QCustomPlot::setCurrentLayer). This means, all new plottables, items etc. are created on this
+  layer by default. Then comes the "grid" layer which contains the QCPGrid instances (which belong
+  tightly to QCPAxis, see \ref QCPAxis::grid). The Axis rect background shall be drawn behind
+  everything else, thus the default QCPAxisRect instance is placed on the "background" layer. Of
+  course, the layer affiliation of the individual objects can be changed as required (\ref
+  QCPLayerable::setLayer).
+
+  \section qcplayer-ordering Controlling the rendering order via layers
+
+  Controlling the ordering of layerables in the plot is easy: Create a new layer in the position
+  you want the layerable to be in, e.g. above "main", with \ref QCustomPlot::addLayer. Then set the
+  current layer with \ref QCustomPlot::setCurrentLayer to that new layer and finally create the
+  objects normally. They will be placed on the new layer automatically, due to the current layer
+  setting. Alternatively you could have also ignored the current layer setting and just moved the
+  objects with \ref QCPLayerable::setLayer to the desired layer after creating them.
+
+  It is also possible to move whole layers. For example, If you want the grid to be shown in front
+  of all plottables/items on the "main" layer, just move it above "main" with
+  QCustomPlot::moveLayer.
+
+  The rendering order within one layer is simply by order of creation or insertion. The item
+  created last (or added last to the layer), is drawn on top of all other objects on that layer.
+
+  When a layer is deleted, the objects on it are not deleted with it, but fall on the layer below
+  the deleted layer, see QCustomPlot::removeLayer.
+
+  \section qcplayer-buffering Replotting only a specific layer
+
+  If the layer mode (\ref setMode) is set to \ref lmBuffered, you can replot only this specific
+  layer by calling \ref replot. In certain situations this can provide better replot performance,
+  compared with a full replot of all layers. Upon creation of a new layer, the layer mode is
+  initialized to \ref lmLogical. The only layer that is set to \ref lmBuffered in a new \ref
+  QCustomPlot instance is the "overlay" layer, containing the selection rect.

+  
+  This function applies the default antialiasing setting to the specified \a painter, using the
+  function \ref applyAntialiasingHint. It is the antialiasing state the painter is put in, when
+  \ref draw is called on the layerable. If the layerable has multiple entities whose antialiasing
+  setting may be specified individually, this function should set the antialiasing state of the
+  most prominent entity. In this case however, the \ref draw function usually calls the specialized
+  versions of this function before drawing each entity, effectively overriding the setting of the
+  default antialiasing hint.
+  
+  <b>First example:</b> QCPGraph has multiple entities that have an antialiasing setting: The graph
+  line, fills and scatters. Those can be configured via QCPGraph::setAntialiased,
+  QCPGraph::setAntialiasedFill and QCPGraph::setAntialiasedScatters. Consequently, there isn't only
+  the QCPGraph::applyDefaultAntialiasingHint function (which corresponds to the graph line's
+  antialiasing), but specialized ones like QCPGraph::applyFillAntialiasingHint and
+  QCPGraph::applyScattersAntialiasingHint. So before drawing one of those entities, QCPGraph::draw
+  calls the respective specialized applyAntialiasingHint function.
+  
+  <b>Second example:</b> QCPItemLine consists only of a line so there is only one antialiasing
+  setting which can be controlled with QCPItemLine::setAntialiased. (This function is inherited by
+  all layerables. The specialized functions, as seen on QCPGraph, must be added explicitly to the
+  respective layerable subclass.) Consequently it only has the normal
+  QCPItemLine::applyDefaultAntialiasingHint. The \ref QCPItemLine::draw function doesn't need to
+  care about setting any antialiasing states, because the default antialiasing hint is already set
+  on the painter when the \ref draw function is called, and that's the state it wants to draw the

+  e.g. \ref bounded, \ref expanded, \ref intersects, \ref intersection, \ref adjusted, \ref
+  contains. Further, addition and subtraction operators (defined in \ref QCPDataSelection) can be
+  used to join/subtract data ranges and data selections (or mixtures), to retrieve a corresponding

+  \brief Describes a data set by holding multiple QCPDataRange instances
+  
+  QCPDataSelection manages multiple instances of QCPDataRange in order to represent any (possibly
+  disjoint) set of data selection.
+  
+  The data selection can be modified with addition and subtraction operators which take
+  QCPDataSelection and QCPDataRange instances, as well as methods such as \ref addDataRange and
+  \ref clear. Read access is provided by \ref dataRange, \ref dataRanges, \ref dataRangeCount, etc.
+  
+  The method \ref simplify is used to join directly adjacent or even overlapping QCPDataRange
+  instances. QCPDataSelection automatically simplifies when using the addition/subtraction
+  operators. The only case when \ref simplify is left to the user, is when calling \ref
+  addDataRange, with the parameter \a simplify explicitly set to false. This is useful if many data
+  ranges will be added to the selection successively and the overhead for simplifying after each
+  iteration shall be avoided. In this case, you should make sure to call \ref simplify after
+  completing the operation.
+  
+  Use \ref enforceType to bring the data selection into a state complying with the constraints for
+  selections defined in \ref QCP::SelectionType.

+/*! \class QCPMarginGroup
+  \brief A margin group allows synchronization of margin sides if working with multiple layout elements.
+  
+  QCPMarginGroup allows you to tie a margin side of two or more layout elements together, such that
+  they will all have the same size, based on the largest required margin in the group.
+  
+  \n
+  \image html QCPMarginGroup.png "Demonstration of QCPMarginGroup"
+  \n
+  
+  In certain situations it is desirable that margins at specific sides are synchronized across
+  layout elements. For example, if one QCPAxisRect is below another one in a grid layout, it will
+  provide a cleaner look to the user if the left and right margins of the two axis rects are of the
+  same size. The left axis of the top axis rect will then be at the same horizontal position as the
+  left axis of the lower axis rect, making them appear aligned. The same applies for the right
+  axes. This is what QCPMarginGroup makes possible.
+  
+  To add/remove a specific side of a layout element to/from a margin group, use the \ref
+  QCPLayoutElement::setMarginGroup method. To completely break apart the margin group, either call
+  \ref clear, or just delete the margin group.
+  
+  \section QCPMarginGroup-example Example
+  
+  First create a margin group:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpmargingroup-creation-1
+  Then set this group on the layout element sides:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpmargingroup-creation-2

+/*! \class QCPLayoutElement
+  \brief The abstract base class for all objects that form \ref thelayoutsystem "the layout system".
+  
+  This is an abstract base class. As such, it can't be instantiated directly, rather use one of its subclasses.
+  
+  A Layout element is a rectangular object which can be placed in layouts. It has an outer rect
+  (QCPLayoutElement::outerRect) and an inner rect (\ref QCPLayoutElement::rect). The difference
+  between outer and inner rect is called its margin. The margin can either be set to automatic or
+  manual (\ref setAutoMargins) on a per-side basis. If a side is set to manual, that margin can be
+  set explicitly with \ref setMargins and will stay fixed at that value. If it's set to automatic,
+  the layout element subclass will control the value itself (via \ref calculateAutoMargin).
+  
+  Layout elements can be placed in layouts (base class QCPLayout) like QCPLayoutGrid. The top level
+  layout is reachable via \ref QCustomPlot::plotLayout, and is a \ref QCPLayoutGrid. Since \ref
+  QCPLayout itself derives from \ref QCPLayoutElement, layouts can be nested.
+  
+  Thus in QCustomPlot one can divide layout elements into two categories: The ones that are
+  invisible by themselves, because they don't draw anything. Their only purpose is to manage the
+  position and size of other layout elements. This category of layout elements usually use
+  QCPLayout as base class. Then there is the category of layout elements which actually draw
+  something. For example, QCPAxisRect, QCPLegend and QCPTextElement are of this category. This does
+  not necessarily mean that the latter category can't have child layout elements. QCPLegend for
+  instance, actually derives from QCPLayoutGrid and the individual legend items are child layout
+  elements in the grid layout.

+/*! \class QCPLayoutGrid
+  \brief A layout that arranges child elements in a grid
+
+  Elements are laid out in a grid with configurable stretch factors (\ref setColumnStretchFactor,
+  \ref setRowStretchFactor) and spacing (\ref setColumnSpacing, \ref setRowSpacing).
+
+  Elements can be added to cells via \ref addElement. The grid is expanded if the specified row or
+  column doesn't exist yet. Whether a cell contains a valid layout element can be checked with \ref
+  hasElement, that element can be retrieved with \ref element. If rows and columns that only have
+  empty cells shall be removed, call \ref simplify. Removal of elements is either done by just
+  adding the element to a different layout or by using the QCPLayout interface \ref take or \ref
+  remove.
+
+  If you use \ref addElement(QCPLayoutElement*) without explicit parameters for \a row and \a
+  column, the grid layout will choose the position according to the current \ref setFillOrder and
+  the wrapping (\ref setWrap).
+
+  Row and column insertion can be performed with \ref insertRow and \ref insertColumn.

+/*! \class QCPAxisTicker
+  \brief The base class tick generator used by QCPAxis to create tick positions and tick labels
+  
+  Each QCPAxis has an internal QCPAxisTicker (or a subclass) in order to generate tick positions
+  and tick labels for the current axis range. The ticker of an axis can be set via \ref
+  QCPAxis::setTicker. Since that method takes a <tt>QSharedPointer<QCPAxisTicker></tt>, multiple
+  axes can share the same ticker instance.
+  
+  This base class generates normal tick coordinates and numeric labels for linear axes. It picks a
+  reasonable tick step (the separation between ticks) which results in readable tick labels. The
+  number of ticks that should be approximately generated can be set via \ref setTickCount.
+  Depending on the current tick step strategy (\ref setTickStepStrategy), the algorithm either
+  sacrifices readability to better match the specified tick count (\ref
+  QCPAxisTicker::tssMeetTickCount) or relaxes the tick count in favor of better tick steps (\ref
+  QCPAxisTicker::tssReadability), which is the default.
+  
+  The following more specialized axis ticker subclasses are available, see details in the
+  respective class documentation:

+  \section axisticker-subclassing Creating own axis tickers
+  
+  Creating own axis tickers can be achieved very easily by sublassing QCPAxisTicker and
+  reimplementing some or all of the available virtual methods.
+
+  In the simplest case you might wish to just generate different tick steps than the other tickers,
+  so you only reimplement the method \ref getTickStep. If you additionally want control over the
+  string that will be shown as tick label, reimplement \ref getTickLabel.
+  
+  If you wish to have complete control, you can generate the tick vectors and tick label vectors
+  yourself by reimplementing \ref createTickVector and \ref createLabelVector. The default
+  implementations use the previously mentioned virtual methods \ref getTickStep and \ref
+  getTickLabel, but your reimplementations don't necessarily need to do so. For example in the case
+  of unequal tick steps, the method \ref getTickStep loses its usefulness and can be ignored.
+  
+  The sub tick count between major ticks can be controlled with \ref getSubTickCount. Full sub tick
+  placement control is obtained by reimplementing \ref createSubTickVector.
+  
+  See the documentation of all these virtual methods in QCPAxisTicker for detailed information
+  about the parameters and expected return values.

+/*! \class QCPAxisTickerDateTime
+  \brief Specialized axis ticker for calendar dates and times as axis ticks
+  
+  \image html axisticker-datetime.png
+  
+  This QCPAxisTicker subclass generates ticks that correspond to real calendar dates and times. The
+  plot axis coordinate is interpreted as Unix Time, so seconds since Epoch (January 1, 1970, 00:00
+  UTC). This is also used for example by QDateTime in the <tt>toTime_t()/setTime_t()</tt> methods
+  with a precision of one second. Since Qt 4.7, millisecond accuracy can be obtained from QDateTime
+  by using <tt>QDateTime::fromMSecsSinceEpoch()/1000.0</tt>. The static methods \ref dateTimeToKey
+  and \ref keyToDateTime conveniently perform this conversion achieving a precision of one
+  millisecond on all Qt versions.
+  
+  The format of the date/time display in the tick labels is controlled with \ref setDateTimeFormat.
+  If a different time spec (time zone) shall be used, see \ref setDateTimeSpec.
+  
+  This ticker produces unequal tick spacing in order to provide intuitive date and time-of-day
+  ticks. For example, if the axis range spans a few years such that there is one tick per year,
+  ticks will be positioned on 1. January of every year. This is intuitive but, due to leap years,
+  will result in slightly unequal tick intervals (visually unnoticeable). The same can be seen in
+  the image above: even though the number of days varies month by month, this ticker generates
+  ticks on the same day of each month.
+  
+  If you would like to change the date/time that is used as a (mathematical) starting date for the
+  ticks, use the \ref setTickOrigin(const QDateTime &origin) method overload, which takes a
+  QDateTime. If you pass 15. July, 9:45 to this method, the yearly ticks will end up on 15. July at
+  9:45 of every year.
+  
+  The ticker can be created and assigned to an axis like this:
+  \snippet documentation/doc-image-generator/mainwindow.cpp axistickerdatetime-creation
+  
+  \note If you rather wish to display relative times in terms of days, hours, minutes, seconds and
+  milliseconds, and are not interested in the intricacies of real calendar dates with months and
+  (leap) years, have a look at QCPAxisTickerTime instead.

+/*! \class QCPAxisTickerTime
+  \brief Specialized axis ticker for time spans in units of milliseconds to days
+  
+  \image html axisticker-time.png
+  
+  This QCPAxisTicker subclass generates ticks that corresponds to time intervals.
+  
+  The format of the time display in the tick labels is controlled with \ref setTimeFormat and \ref
+  setFieldWidth. The time coordinate is in the unit of seconds with respect to the time coordinate
+  zero. Unlike with QCPAxisTickerDateTime, the ticks don't correspond to a specific calendar date
+  and time.
+  
+  The time can be displayed in milliseconds, seconds, minutes, hours and days. Depending on the
+  largest available unit in the format specified with \ref setTimeFormat, any time spans above will
+  be carried in that largest unit. So for example if the format string is "%m:%s" and a tick at
+  coordinate value 7815 (being 2 hours, 10 minutes and 15 seconds) is created, the resulting tick
+  label will show "130:15" (130 minutes, 15 seconds). If the format string is "%h:%m:%s", the hour
+  unit will be used and the label will thus be "02:10:15". Negative times with respect to the axis
+  zero will carry a leading minus sign.
+  
+  The ticker can be created and assigned to an axis like this:
+  \snippet documentation/doc-image-generator/mainwindow.cpp axistickertime-creation
+  
+  Here is an example of a time axis providing time information in days, hours and minutes. Due to
+  the axis range spanning a few days and the wanted tick count (\ref setTickCount), the ticker
+  decided to use tick steps of 12 hours:
+  
+  \image html axisticker-time2.png
+  
+  The format string for this example is
+  \snippet documentation/doc-image-generator/mainwindow.cpp axistickertime-creation-2
+  
+  \note If you rather wish to display calendar dates and times, have a look at QCPAxisTickerDateTime
+  instead.

+  
+  \a formatCode is a string of one, two or three characters. The first character is identical to
+  the normal format code used by Qt. In short, this means: 'e'/'E' scientific format, 'f' fixed
+  format, 'g'/'G' scientific or fixed, whichever is shorter.
+  
+  The second and third characters are optional and specific to QCustomPlot:\n
+  If the first char was 'e' or 'g', numbers are/might be displayed in the scientific format, e.g.
+  "5.5e9", which is ugly in a plot. So when the second char of \a formatCode is set to 'b' (for
+  "beautiful"), those exponential numbers are formatted in a more natural way, i.e. "5.5
+  [multiplication sign] 10 [superscript] 9". By default, the multiplication sign is a centered dot.
+  If instead a cross should be shown (as is usual in the USA), the third char of \a formatCode can
+  be set to 'c'. The inserted multiplication signs are the UTF-8 characters 215 (0xD7) for the
+  cross and 183 (0xB7) for the dot.
+  
+  Examples for \a formatCode:
+  \li \c g normal format code behaviour. If number is small, fixed format is used, if number is large,
+  normal scientific format is used
+  \li \c gb If number is small, fixed format is used, if number is large, scientific format is used with
+  beautifully typeset decimal powers and a dot as multiplication sign
+  \li \c ebc All numbers are in scientific format with beautifully typeset decimal power and a cross as
+  multiplication sign
+  \li \c fb illegal format code, since fixed format doesn't support (or need) beautifully typeset decimal
+  powers. Format code will be reduced to 'f'.
+  \li \c hello illegal format code, since first char is not 'e', 'E', 'f', 'g' or 'G'. Current format
+  code will not be changed.

+/*! \class QCPScatterStyle
+  \brief Represents the visual appearance of scatter points
+  
+  This class holds information about shape, color and size of scatter points. In plottables like
+  QCPGraph it is used to store how scatter points shall be drawn. For example, \ref
+  QCPGraph::setScatterStyle takes a QCPScatterStyle instance.
+  
+  A scatter style consists of a shape (\ref setShape), a line color (\ref setPen) and possibly a
+  fill (\ref setBrush), if the shape provides a fillable area. Further, the size of the shape can
+  be controlled with \ref setSize.
+
+  \section QCPScatterStyle-defining Specifying a scatter style
+  
+  You can set all these configurations either by calling the respective functions on an instance:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpscatterstyle-creation-1
+  
+  Or you can use one of the various constructors that take different parameter combinations, making
+  it easy to specify a scatter style in a single call, like so:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpscatterstyle-creation-2
+  
+  \section QCPScatterStyle-undefinedpen Leaving the color/pen up to the plottable
+  
+  There are two constructors which leave the pen undefined: \ref QCPScatterStyle() and \ref
+  QCPScatterStyle(ScatterShape shape, double size). If those constructors are used, a call to \ref
+  isPenDefined will return false. It leads to scatter points that inherit the pen from the
+  plottable that uses the scatter style. Thus, if such a scatter style is passed to QCPGraph, the line
+  color of the graph (\ref QCPGraph::setPen) will be used by the scatter points. This makes
+  it very convenient to set up typical scatter settings:
+  
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpscatterstyle-shortcreation
+
+  Notice that it wasn't even necessary to explicitly call a QCPScatterStyle constructor. This works
+  because QCPScatterStyle provides a constructor that can transform a \ref ScatterShape directly
+  into a QCPScatterStyle instance (that's the \ref QCPScatterStyle(ScatterShape shape, double size)
+  constructor with a default for \a size). In those cases, C++ allows directly supplying a \ref
+  ScatterShape, where actually a QCPScatterStyle is expected.
+  
+  \section QCPScatterStyle-custompath-and-pixmap Custom shapes and pixmaps
+  
+  QCPScatterStyle supports drawing custom shapes and arbitrary pixmaps as scatter points.
+
+  For custom shapes, you can provide a QPainterPath with the desired shape to the \ref
+  setCustomPath function or call the constructor that takes a painter path. The scatter shape will
+  automatically be set to \ref ssCustom.
+  
+  For pixmaps, you call \ref setPixmap with the desired QPixmap. Alternatively you can use the
+  constructor that takes a QPixmap. The scatter shape will automatically be set to \ref ssPixmap.
+  Note that \ref setSize does not influence the appearance of the pixmap.

+/*! \class QCPSelectionDecorator
+  \brief Controls how a plottable's data selection is drawn
+  
+  Each \ref QCPAbstractPlottable instance has one \ref QCPSelectionDecorator (accessible via \ref
+  QCPAbstractPlottable::selectionDecorator) and uses it when drawing selected segments of its data.
+  
+  The selection decorator controls both pen (\ref setPen) and brush (\ref setBrush), as well as the
+  scatter style (\ref setScatterStyle) if the plottable draws scatters. Since a \ref
+  QCPScatterStyle is itself composed of different properties such as color shape and size, the
+  decorator allows specifying exactly which of those properties shall be used for the selected data
+  point, via \ref setUsedScatterProperties.
+  
+  A \ref QCPSelectionDecorator subclass instance can be passed to a plottable via \ref
+  QCPAbstractPlottable::setSelectionDecorator, allowing greater customizability of the appearance
+  of selected segments.
+  
+  Use \ref copyFrom to easily transfer the settings of one decorator to another one. This is
+  especially useful since plottables take ownership of the passed selection decorator, and thus the
+  same decorator instance can not be passed to multiple plottables.
+  
+  Selection decorators can also themselves perform drawing operations by reimplementing \ref
+  drawDecoration, which is called by the plottable's draw method. The base class \ref
+  QCPSelectionDecorator does not make use of this however. For example, \ref
+  QCPSelectionDecoratorBracket draws brackets around selected data segments.

+
+/*! \class QCPAbstractPlottable
+  \brief The abstract base class for all data representing objects in a plot.
+
+  It defines a very basic interface like name, pen, brush, visibility etc. Since this class is
+  abstract, it can't be instantiated. Use one of the subclasses or create a subclass yourself to
+  create new ways of displaying data (see "Creating own plottables" below). Plottables that display
+  one-dimensional data (i.e. data points have a single key dimension and one or multiple values at
+  each key) are based off of the template subclass \ref QCPAbstractPlottable1D, see details
+  there.
+  
+  All further specifics are in the subclasses, for example:
+  \li A normal graph with possibly a line and/or scatter points \ref QCPGraph
+  (typically created with \ref QCustomPlot::addGraph)
+  \li A parametric curve: \ref QCPCurve
+  \li A bar chart: \ref QCPBars
+  \li A statistical box plot: \ref QCPStatisticalBox
+  \li A color encoded two-dimensional map: \ref QCPColorMap
+  \li An OHLC/Candlestick chart: \ref QCPFinancial
+  
+  \section plottables-subclassing Creating own plottables
+  
+  Subclassing directly from QCPAbstractPlottable is only recommended if you wish to display
+  two-dimensional data like \ref QCPColorMap, i.e. two logical key dimensions and one (or more)
+  data dimensions. If you want to display data with only one logical key dimension, you should
+  rather derive from \ref QCPAbstractPlottable1D.
+  
+  If subclassing QCPAbstractPlottable directly, these are the pure virtual functions you must
+  implement:
+  \li \ref selectTest
+  \li \ref draw
+  \li \ref drawLegendIcon
+  \li \ref getKeyRange
+  \li \ref getValueRange
+  
+  See the documentation of those functions for what they need to do.
+  
+  For drawing your plot, you can use the \ref coordsToPixels functions to translate a point in plot
+  coordinates to pixel coordinates. This function is quite convenient, because it takes the
+  orientation of the key and value axes into account for you (x and y are swapped when the key axis
+  is vertical and the value axis horizontal). If you are worried about performance (i.e. you need
+  to translate many points in a loop like QCPGraph), you can directly use \ref
+  QCPAxis::coordToPixel. However, you must then take care about the orientation of the axis
+  yourself.
+  
+  Here are some important members you inherit from QCPAbstractPlottable:
+  <table>
+  <tr>
+    <td>QCustomPlot *\b mParentPlot</td>
+    <td>A pointer to the parent QCustomPlot instance. The parent plot is inferred from the axes that are passed in the constructor.</td>
+  </tr><tr>
+    <td>QString \b mName</td>
+    <td>The name of the plottable.</td>
+  </tr><tr>
+    <td>QPen \b mPen</td>
+    <td>The generic pen of the plottable. You should use this pen for the most prominent data representing lines in the plottable
+        (e.g QCPGraph uses this pen for its graph lines and scatters)</td>
+  </tr><tr>
+    <td>QBrush \b mBrush</td>
+    <td>The generic brush of the plottable. You should use this brush for the most prominent fillable structures in the plottable
+        (e.g. QCPGraph uses this brush to control filling under the graph)</td>
+  </tr><tr>
+    <td>QPointer<\ref QCPAxis> \b mKeyAxis, \b mValueAxis</td>
+    <td>The key and value axes this plottable is attached to. Call their QCPAxis::coordToPixel functions to translate coordinates
+        to pixels in either the key or value dimension. Make sure to check whether the pointer is null before using it. If one of
+        the axes is null, don't draw the plottable.</td>
+  </tr><tr>
+    <td>\ref QCPSelectionDecorator \b mSelectionDecorator</td>
+    <td>The currently set selection decorator which specifies how selected data of the plottable shall be drawn and decorated.
+        When drawing your data, you must consult this decorator for the appropriate pen/brush before drawing unselected/selected data segments.
+        Finally, you should call its \ref QCPSelectionDecorator::drawDecoration method at the end of your \ref draw implementation.</td>
+  </tr><tr>
+    <td>\ref QCP::SelectionType \b mSelectable</td>
+    <td>In which composition, if at all, this plottable's data may be selected. Enforcing this setting on the data selection is done
+        by QCPAbstractPlottable automatically.</td>
+  </tr><tr>
+    <td>\ref QCPDataSelection \b mSelection</td>
+    <td>Holds the current selection state of the plottable's data, i.e. the selected data ranges (\ref QCPDataRange).</td>

+  anchor.
+
+  For example, a QCPItemRect is defined by its positions \a topLeft and \a bottomRight.

+  calling QCPItemPosition::setParentAnchor on \a start, passing the wanted anchor of the
+  QCPItemRect. This way the start of the line will now always follow the respective anchor location
+  on the rect item.
+  
+  Note that QCPItemPosition derives from QCPItemAnchor, so every position can also serve as an

+/*! \class QCPItemPosition
+  \brief Manages the position of an item.
+  
+  Every item has at least one public QCPItemPosition member pointer which provides ways to position the
+  item on the QCustomPlot surface. Some items have multiple positions, for example QCPItemRect has two:
+  \a topLeft and \a bottomRight.
+
+  QCPItemPosition has a type (\ref PositionType) that can be set with \ref setType. This type
+  defines how coordinates passed to \ref setCoords are to be interpreted, e.g. as absolute pixel
+  coordinates, as plot coordinates of certain axes, etc. For more advanced plots it is also
+  possible to assign different types per X/Y coordinate of the position (see \ref setTypeX, \ref
+  setTypeY). This way an item could be positioned at a fixed pixel distance from the top in the Y
+  direction, while following a plot coordinate in the X direction.
+
+  A QCPItemPosition may have a parent QCPItemAnchor, see \ref setParentAnchor. This way you can tie
+  multiple items together. If the QCPItemPosition has a parent, its coordinates (\ref setCoords)
+  are considered to be absolute pixels in the reference frame of the parent anchor, where (0, 0)
+  means directly ontop of the parent anchor. For example, You could attach the \a start position of
+  a QCPItemLine to the \a bottom anchor of a QCPItemText to make the starting point of the line

+  documentation of \ref PositionType for details. For \ref ptAxisRectRatio, note that you can specify

+  Note that the position type \ref ptPlotCoords is only available (and sensible) when the position

+  specific item has at least one QCPItemPosition member which controls the positioning. Some items
+  are defined by more than one coordinate and thus have two or more QCPItemPosition members (For
+  example, QCPItemRect has \a topLeft and \a bottomRight).
+  
+  This abstract base class defines a very basic interface like visibility and clipping. Since this
+  class is abstract, it can't be instantiated. Use one of the subclasses or create a subclass
+  yourself to create new items.
+  
+  The built-in items are:
+  <table>
+  <tr><td>QCPItemLine</td><td>A line defined by a start and an end point. May have different ending styles on each side (e.g. arrows).</td></tr>
+  <tr><td>QCPItemStraightLine</td><td>A straight line defined by a start and a direction point. Unlike QCPItemLine, the straight line is infinitely long and has no endings.</td></tr>
+  <tr><td>QCPItemCurve</td><td>A curve defined by start, end and two intermediate control points. May have different ending styles on each side (e.g. arrows).</td></tr>
+  <tr><td>QCPItemRect</td><td>A rectangle</td></tr>
+  <tr><td>QCPItemEllipse</td><td>An ellipse</td></tr>
+  <tr><td>QCPItemPixmap</td><td>An arbitrary pixmap</td></tr>
+  <tr><td>QCPItemText</td><td>A text label</td></tr>
+  <tr><td>QCPItemBracket</td><td>A bracket which may be used to reference/highlight certain parts in the plot.</td></tr>
+  <tr><td>QCPItemTracer</td><td>An item that can be attached to a QCPGraph and sticks to its data points, given a key coordinate.</td></tr>
+  </table>
+  
+  \section items-clipping Clipping
+
+  Items are by default clipped to the main axis rect (they are only visible inside the axis rect).
+  To make an item visible outside that axis rect, disable clipping via \ref setClipToAxisRect
+  "setClipToAxisRect(false)".
+
+  On the other hand if you want the item to be clipped to a different axis rect, specify it via
+  \ref setClipAxisRect. This clipAxisRect property of an item is only used for clipping behaviour, and
+  in principle is independent of the coordinate axes the item might be tied to via its position
+  members (\ref QCPItemPosition::setAxes). However, it is common that the axis rect for clipping
+  also contains the axes used for the item positions.
+  
+  \section items-using Using items
+  
+  First you instantiate the item you want to use and add it to the plot:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-1
+  by default, the positions of the item are bound to the x- and y-Axis of the plot. So we can just
+  set the plot coordinates where the line should start/end:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-2
+  If we don't want the line to be positioned in plot coordinates but a different coordinate system,
+  e.g. absolute pixel positions on the QCustomPlot surface, we need to change the position type like this:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-3
+  Then we can set the coordinates, this time in pixels:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-4
+  and make the line visible on the entire QCustomPlot, by disabling clipping to the axis rect:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-5
+  
+  For more advanced plots, it is even possible to set different types and parent anchors per X/Y
+  coordinate of an item position, using for example \ref QCPItemPosition::setTypeX or \ref
+  QCPItemPosition::setParentAnchorX. For details, see the documentation of \ref QCPItemPosition.
+  
+  \section items-subclassing Creating own items
+  
+  To create an own item, you implement a subclass of QCPAbstractItem. These are the pure
+  virtual functions, you must implement:
+  \li \ref selectTest
+  \li \ref draw
+  
+  See the documentation of those functions for what they need to do.
+  
+  \subsection items-positioning Allowing the item to be positioned
+  
+  As mentioned, item positions are represented by QCPItemPosition members. Let's assume the new item shall
+  have only one point as its position (as opposed to two like a rect or multiple like a polygon). You then add
+  a public member of type QCPItemPosition like so:
+  
+  \code QCPItemPosition * const myPosition;\endcode
+  
+  the const makes sure the pointer itself can't be modified from the user of your new item (the QCPItemPosition
+  instance it points to, can be modified, of course).
+  The initialization of this pointer is made easy with the \ref createPosition function. Just assign
+  the return value of this function to each QCPItemPosition in the constructor of your item. \ref createPosition
+  takes a string which is the name of the position, typically this is identical to the variable name.
+  For example, the constructor of QCPItemExample could look like this:
+  
+  \code
+  QCPItemExample::QCPItemExample(QCustomPlot *parentPlot) :
+    QCPAbstractItem(parentPlot),
+    myPosition(createPosition("myPosition"))
+  {
+    // other constructor code
+  }
+  \endcode
+  
+  \subsection items-drawing The draw function
+  
+  To give your item a visual representation, reimplement the \ref draw function and use the passed
+  QCPPainter to draw the item. You can retrieve the item position in pixel coordinates from the
+  position member(s) via \ref QCPItemPosition::pixelPosition.
+
+  To optimize performance you should calculate a bounding rect first (don't forget to take the pen
+  width into account), check whether it intersects the \ref clipRect, and only draw the item at all
+  if this is the case.
+  
+  \subsection items-selection The selectTest function
+  
+  Your implementation of the \ref selectTest function may use the helpers \ref
+  QCPVector2D::distanceSquaredToLine and \ref rectDistance. With these, the implementation of the
+  selection test becomes significantly simpler for most items. See the documentation of \ref
+  selectTest for what the function parameters mean and what the function should return.
+  
+  \subsection anchors Providing anchors
+  
+  Providing anchors (QCPItemAnchor) starts off like adding a position. First you create a public
+  member, e.g.
+  
+  \code QCPItemAnchor * const bottom;\endcode
+
+  and create it in the constructor with the \ref createAnchor function, assigning it a name and an
+  anchor id (an integer enumerating all anchors on the item, you may create an own enum for this).
+  Since anchors can be placed anywhere, relative to the item's position(s), your item needs to
+  provide the position of every anchor with the reimplementation of the \ref anchorPixelPosition(int
+  anchorId) function.
+  
+  In essence the QCPItemAnchor is merely an intermediary that itself asks your item for the pixel
+  position when anything attached to the anchor needs to know the coordinates.

+  For details how to control which axes the user may drag/zoom and in what orientations, see \ref

+  \ref QCPAxisRect::setRangeZoomAxes.
+  
+  <b>Plottable data selection</b> is controlled by \ref QCP::iSelectPlottables. If \ref
+  QCP::iSelectPlottables is set, the user may select plottables (graphs, curves, bars,...) and
+  their data by clicking on them or in their vicinity (\ref setSelectionTolerance). Whether the
+  user can actually select a plottable and its data can further be restricted with the \ref
+  QCPAbstractPlottable::setSelectable method on the specific plottable. For details, see the
+  special page about the \ref dataselection "data selection mechanism". To retrieve a list of all
+  currently selected plottables, call \ref selectedPlottables. If you're only interested in
+  QCPGraphs, you may use the convenience function \ref selectedGraphs.
+  
+  <b>Item selection</b> is controlled by \ref QCP::iSelectItems. If \ref QCP::iSelectItems is set, the user
+  may select items (QCPItemLine, QCPItemText,...) by clicking on them or in their vicinity. To find
+  out whether a specific item is selected, call QCPAbstractItem::selected(). To retrieve a list of
+  all currently selected items, call \ref selectedItems.
+  
+  <b>Axis selection</b> is controlled with \ref QCP::iSelectAxes. If \ref QCP::iSelectAxes is set, the user
+  may select parts of the axes by clicking on them. What parts exactly (e.g. Axis base line, tick
+  labels, axis label) are selectable can be controlled via \ref QCPAxis::setSelectableParts for
+  each axis. To retrieve a list of all axes that currently contain selected parts, call \ref
+  selectedAxes. Which parts of an axis are selected, can be retrieved with QCPAxis::selectedParts().
+  
+  <b>Legend selection</b> is controlled with \ref QCP::iSelectLegend. If this is set, the user may
+  select the legend itself or individual items by clicking on them. What parts exactly are
+  selectable can be controlled via \ref QCPLegend::setSelectableParts. To find out whether the
+  legend or any of its child items are selected, check the value of QCPLegend::selectedParts. To
+  find out which child items are selected, call \ref QCPLegend::selectedItems.
+  
+  <b>All other selectable elements</b> The selection of all other selectable objects (e.g.
+  QCPTextElement, or your own layerable subclasses) is controlled with \ref QCP::iSelectOther. If set, the
+  user may select those objects by clicking on them. To find out which are currently selected, you
+  need to check their selected state explicitly.
+  
+  If the selection state has changed by user interaction, the \ref selectionChangedByUser signal is

+  \warning This is still an experimental feature and its performance depends on the system that it
+  runs on. Having multiple QCustomPlot widgets in one application with enabled OpenGL rendering
+  might cause context conflicts on some systems.
+  
+  This method allows to enable OpenGL plot rendering, for increased plotting performance of
+  graphically demanding plots (thick lines, translucent fills, etc.).
+
+  If \a enabled is set to true, QCustomPlot will try to initialize OpenGL and, if successful,
+  continue plotting with hardware acceleration. The parameter \a multisampling controls how many
+  samples will be used per pixel, it essentially controls the antialiasing quality. If \a
+  multisampling is set too high for the current graphics hardware, the maximum allowed value will
+  be used.
+
+  You can test whether switching to OpenGL rendering was successful by checking whether the
+  according getter \a QCustomPlot::openGl() returns true. If the OpenGL initialization fails,
+  rendering continues with the regular software rasterizer, and an according qDebug output is
+  generated.
+
+  If switching to OpenGL was successful, this method disables label caching (\ref setPlottingHint
+  "setPlottingHint(QCP::phCacheLabels, false)") and turns on QCustomPlot's antialiasing override
+  for all elements (\ref setAntialiasedElements "setAntialiasedElements(QCP::aeAll)"), leading to a
+  higher quality output. The antialiasing override allows for pixel-grid aligned drawing in the
+  OpenGL paint device. As stated before, in OpenGL rendering the actual antialiasing of the plot is
+  controlled with \a multisampling. If \a enabled is set to false, the antialiasing/label caching
+  settings are restored to what they were before OpenGL was enabled, if they weren't altered in the
+  meantime.
+
+  \note OpenGL support is only enabled if QCustomPlot is compiled with the macro \c QCUSTOMPLOT_USE_OPENGL
+  defined. This define must be set before including the QCustomPlot header both during compilation
+  of the QCustomPlot library as well as when compiling your application. It is best to just include
+  the line <tt>DEFINES += QCUSTOMPLOT_USE_OPENGL</tt> in the respective qmake project files.
+  \note If you are using a Qt version before 5.0, you must also add the module "opengl" to your \c
+  QT variable in the qmake project files. For Qt versions 5.0 and higher, QCustomPlot switches to a
+  newer OpenGL interface which is already in the "gui" module.

+

+  afterReplot is emitted. It is safe to mutually connect the replot slot with any of those two

+  Saves a PNG image file to \a fileName on disc. The output plot will have the dimensions \a width
+  and \a height in pixels, multiplied by \a scale. If either \a width or \a height is zero, the
+  current width and height of the QCustomPlot widget is used instead. Line widths and texts etc.
+  are not scaled up when larger widths/heights are used. If you want that effect, use the \a scale
+  parameter.
+
+  For example, if you set both \a width and \a height to 100 and \a scale to 2, you will end up with an
+  image file of size 200*200 in which all graphical elements are scaled up by factor 2 (line widths,
+  texts, etc.). This scaling is not done by stretching a 100*100 image, the result will have full
+  200*200 pixel resolution.
+
+  If you use a high scaling factor, it is recommended to enable antialiasing for all elements by
+  temporarily setting \ref QCustomPlot::setAntialiasedElements to \ref QCP::aeAll as this allows
+  QCustomPlot to place objects with sub-pixel accuracy.
+
+  image compression can be controlled with the \a quality parameter which must be between 0 and 100
+  or -1 to use the default setting.
+
+  The \a resolution will be written to the image file header and has no direct consequence for the
+  quality or the pixel size. However, if opening the image with a tool which respects the metadata,
+  it will be able to scale the image to match either a given size in real units of length (inch,
+  centimeters, etc.), or the target display DPI. You can specify in which units \a resolution is
+  given, by setting \a resolutionUnit. The \a resolution is converted to the format's expected
+  resolution unit internally.
+
+  Returns true on success. If this function fails, most likely the PNG format isn't supported by
+  the system, see Qt docs about QImageWriter::supportedImageFormats().
+
+  The objects of the plot will appear in the current selection state. If you don't want any selected

+/*! \class QCPColorGradient
+  \brief Defines a color gradient for use with e.g. \ref QCPColorMap
+  
+  This class describes a color gradient which can be used to encode data with color. For example,
+  QCPColorMap and QCPColorScale have \ref QCPColorMap::setGradient "setGradient" methods which
+  take an instance of this class. Colors are set with \ref setColorStopAt(double position, const QColor &color)
+  with a \a position from 0 to 1. In between these defined color positions, the
+  color will be interpolated linearly either in RGB or HSV space, see \ref setColorInterpolation.
+
+  Alternatively, load one of the preset color gradients shown in the image below, with \ref
+  loadPreset, or by directly specifying the preset in the constructor.
+  
+  Apart from red, green and blue components, the gradient also interpolates the alpha values of the
+  configured color stops. This allows to display some portions of the data range as transparent in
+  the plot.
+  
+  \image html QCPColorGradient.png
+  
+  The \ref QCPColorGradient(GradientPreset preset) constructor allows directly converting a \ref
+  GradientPreset to a QCPColorGradient. This means that you can directly pass \ref GradientPreset
+  to all the \a setGradient methods, e.g.:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorgradient-setgradient
+  
+  The total number of levels used in the gradient can be set with \ref setLevelCount. Whether the
+  color gradient shall be applied periodically (wrapping around) to data values that lie outside
+  the data range specified on the plottable instance can be controlled with \ref setPeriodic.

+/*! \class QCPAxisRect
+  \brief Holds multiple axes and arranges them in a rectangular shape.
+  
+  This class represents an axis rect, a rectangular area that is bounded on all sides with an
+  arbitrary number of axes.
+  
+  Initially QCustomPlot has one axis rect, accessible via QCustomPlot::axisRect(). However, the
+  layout system allows to have multiple axis rects, e.g. arranged in a grid layout
+  (QCustomPlot::plotLayout).
+  
+  By default, QCPAxisRect comes with four axes, at bottom, top, left and right. They can be
+  accessed via \ref axis by providing the respective axis type (\ref QCPAxis::AxisType) and index.
+  If you need all axes in the axis rect, use \ref axes. The top and right axes are set to be
+  invisible initially (QCPAxis::setVisible). To add more axes to a side, use \ref addAxis or \ref
+  addAxes. To remove an axis, use \ref removeAxis.
+  
+  The axis rect layerable itself only draws a background pixmap or color, if specified (\ref
+  setBackground). It is placed on the "background" layer initially (see \ref QCPLayer for an
+  explanation of the QCustomPlot layer system). The axes that are held by the axis rect can be
+  placed on other layers, independently of the axis rect.
+  
+  Every axis rect has a child layout of type \ref QCPLayoutInset. It is accessible via \ref
+  insetLayout and can be used to have other layout elements (or even other layouts with multiple
+  elements) hovering inside the axis rect.
+  
+  If an axis rect is clicked and dragged, it processes this by moving certain axis ranges. The
+  behaviour can be controlled with \ref setRangeDrag and \ref setRangeDragAxes. If the mouse wheel
+  is scrolled while the cursor is on the axis rect, certain axes are scaled. This is controllable
+  via \ref setRangeZoom, \ref setRangeZoomAxes and \ref setRangeZoomFactor. These interactions are
+  only enabled if \ref QCustomPlot::setInteractions contains \ref QCP::iRangeDrag and \ref
+  QCP::iRangeZoom.

+/*! \class QCPPlottableLegendItem
+  \brief A legend item representing a plottable with an icon and the plottable name.
+  
+  This is the standard legend item for plottables. It displays an icon of the plottable next to the
+  plottable name. The icon is drawn by the respective plottable itself (\ref
+  QCPAbstractPlottable::drawLegendIcon), and tries to give an intuitive symbol for the plottable.
+  For example, the QCPGraph draws a centered horizontal line and/or a single scatter point in the
+  middle.
+  
+  Legend items of this type are always associated with one plottable (retrievable via the
+  plottable() function and settable with the constructor). You may change the font of the plottable
+  name with \ref setFont. Icon padding and border pen is taken from the parent QCPLegend, see \ref
+  QCPLegend::setIconBorderPen and \ref QCPLegend::setIconTextPadding.
+
+  The function \ref QCPAbstractPlottable::addToLegend/\ref QCPAbstractPlottable::removeFromLegend
+  creates/removes legend items of this type.
+  
+  Since QCPLegend is based on QCPLayoutGrid, a legend item itself is just a subclass of
+  QCPLayoutElement. While it could be added to a legend (or any other layout) via the normal layout
+  interface, QCPLegend has specialized functions for handling legend items conveniently, see the

+/*! \class QCPLegend
+  \brief Manages a legend inside a QCustomPlot.
+
+  A legend is a small box somewhere in the plot which lists plottables with their name and icon.
+
+  A legend is populated with legend items by calling \ref QCPAbstractPlottable::addToLegend on the
+  plottable, for which a legend item shall be created. In the case of the main legend (\ref
+  QCustomPlot::legend), simply adding plottables to the plot while \ref
+  QCustomPlot::setAutoAddPlottableToLegend is set to true (the default) creates corresponding
+  legend items. The legend item associated with a certain plottable can be removed with \ref
+  QCPAbstractPlottable::removeFromLegend. However, QCPLegend also offers an interface to add and
+  manipulate legend items directly: \ref item, \ref itemWithPlottable, \ref itemCount, \ref
+  addItem, \ref removeItem, etc.
+
+  Since \ref QCPLegend derives from \ref QCPLayoutGrid, it can be placed in any position a \ref
+  QCPLayoutElement may be positioned. The legend items are themselves \ref QCPLayoutElement
+  "QCPLayoutElements" which are placed in the grid layout of the legend. \ref QCPLegend only adds
+  an interface specialized for handling child elements of type \ref QCPAbstractLegendItem, as
+  mentioned above. In principle, any other layout elements may also be added to a legend via the
+  normal \ref QCPLayoutGrid interface. See the special page about \link thelayoutsystem The Layout
+  System\endlink for examples on how to add other elements to the legend and move it outside the axis
+  rect.
+
+  Use the methods \ref setFillOrder and \ref setWrap inherited from \ref QCPLayoutGrid to control
+  in which order (column first or row first) the legend is filled up when calling \ref addItem, and
+  at which column or row wrapping occurs.
+
+  By default, every QCustomPlot has one legend (\ref QCustomPlot::legend) which is placed in the
+  inset layout of the main axis rect (\ref QCPAxisRect::insetLayout). To move the legend to another
+  position inside the axis rect, use the methods of the \ref QCPLayoutInset. To move the legend
+  outside of the axis rect, place it anywhere else with the \ref QCPLayout/\ref QCPLayoutElement
+  interface.

+
+/*! \class QCPColorScale
+  \brief A color scale for use with color coding data such as QCPColorMap
+  
+  This layout element can be placed on the plot to correlate a color gradient with data values. It
+  is usually used in combination with one or multiple \ref QCPColorMap "QCPColorMaps".
+
+  \image html QCPColorScale.png
+  
+  The color scale can be either horizontal or vertical, as shown in the image above. The
+  orientation and the side where the numbers appear is controlled with \ref setType.
+  
+  Use \ref QCPColorMap::setColorScale to connect a color map with a color scale. Once they are
+  connected, they share their gradient, data range and data scale type (\ref setGradient, \ref
+  setDataRange, \ref setDataScaleType). Multiple color maps may be associated with a single color
+  scale, to make them all synchronize these properties.
+  
+  To have finer control over the number display and axis behaviour, you can directly access the
+  \ref axis. See the documentation of QCPAxis for details about configuring axes. For example, if
+  you want to change the number of automatically generated ticks, call
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorscale-tickcount
+  
+  Placing a color scale next to the main axis rect works like with any other layout element:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorscale-creation
+  In this case we have placed it to the right of the default axis rect, so it wasn't necessary to
+  call \ref setType, since \ref QCPAxis::atRight is already the default. The text next to the color
+  scale can be set with \ref setLabel.
+  
+  For optimum appearance (like in the image above), it may be desirable to line up the axis rect and
+  the borders of the color scale. Use a \ref QCPMarginGroup to achieve this:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorscale-margingroup
+  
+  Color scales are initialized with a non-zero minimum top and bottom margin (\ref
+  setMinimumMargins), because vertical color scales are most common and the minimum top/bottom
+  margin makes sure it keeps some distance to the top/bottom widget border. So if you change to a
+  horizontal color scale by setting \ref setType to \ref QCPAxis::atBottom or \ref QCPAxis::atTop, you
+  might want to also change the minimum margins accordingly, e.g. <tt>setMinimumMargins(QMargins(6, 0, 6, 0))</tt>.

+  setDataScaleType (\ref QCPAxis::setScaleType), and the method \ref setLabel (\ref
+  QCPAxis::setLabel). As they each are connected, it does not matter whether you use the method on

+/*! \class QCPGraph
+  \brief A plottable representing a graph in a plot.
+
+  \image html QCPGraph.png
+  
+  Usually you create new graphs by calling QCustomPlot::addGraph. The resulting instance can be
+  accessed via QCustomPlot::graph.
+
+  To plot data, assign it with the \ref setData or \ref addData functions. Alternatively, you can
+  also access and modify the data via the \ref data method, which returns a pointer to the internal
+  \ref QCPGraphDataContainer.
+  
+  Graphs are used to display single-valued data. Single-valued means that there should only be one
+  data point per unique key coordinate. In other words, the graph can't have \a loops. If you do
+  want to plot non-single-valued curves, rather use the QCPCurve plottable.
+  
+  Gaps in the graph line can be created by adding data points with NaN as value
+  (<tt>qQNaN()</tt> or <tt>std::numeric_limits<double>::quiet_NaN()</tt>) in between the two data points that shall be
+  separated.
+  
+  \section qcpgraph-appearance Changing the appearance
+  
+  The appearance of the graph is mainly determined by the line style, scatter style, brush and pen
+  of the graph (\ref setLineStyle, \ref setScatterStyle, \ref setBrush, \ref setPen).
+  
+  \subsection filling Filling under or between graphs
+  
+  QCPGraph knows two types of fills: Normal graph fills towards the zero-value-line parallel to
+  the key axis of the graph, and fills between two graphs, called channel fills. To enable a fill,
+  just set a brush with \ref setBrush which is neither Qt::NoBrush nor fully transparent.
+  
+  By default, a normal fill towards the zero-value-line will be drawn. To set up a channel fill
+  between this graph and another one, call \ref setChannelFillGraph with the other graph as
+  parameter.

+  sampling technique can drastically improve the replot performance for graphs with a larger number
+  of points (e.g. above 10,000), without notably changing the appearance of the graph.
+  
+  By default, adaptive sampling is enabled. Even if enabled, QCustomPlot decides whether adaptive
+  sampling shall actually be used on a per-graph basis. So leaving adaptive sampling enabled has no
+  disadvantage in almost all cases.
+  
+  \image html adaptive-sampling-line.png "A line plot of 500,000 points without and with adaptive sampling"
+  
+  As can be seen, line plots experience no visual degradation from adaptive sampling. Outliers are
+  reproduced reliably, as well as the overall shape of the data set. The replot time reduces
+  dramatically though. This allows QCustomPlot to display large amounts of data in realtime.
+  
+  \image html adaptive-sampling-scatter.png "A scatter plot of 100,000 points without and with adaptive sampling"
+  
+  Care must be taken when using high-density scatter plots in combination with adaptive sampling.
+  The adaptive sampling algorithm treats scatter plots more carefully than line plots which still
+  gives a significant reduction of replot times, but not quite as much as for line plots. This is
+  because scatter plots inherently need more data points to be preserved in order to still resemble
+  the original, non-adaptive-sampling plot. As shown above, the results still aren't quite
+  identical, as banding occurs for the outer data points. This is in fact intentional, such that
+  the boundaries of the data cloud stay visible to the viewer. How strong the banding appears,
+  depends on the point density, i.e. the number of points in the plot.
+  
+  For some situations with scatter plots it might thus be desirable to manually turn adaptive
+  sampling off. For example, when saving the plot to disk. This can be achieved by setting \a
+  enabled to false before issuing a command like \ref QCustomPlot::savePng, and setting \a enabled

+  \brief A plottable representing a parametric curve in a plot.
+  
+  \image html QCPCurve.png
+  
+  Unlike QCPGraph, plottables of this type may have multiple points with the same key coordinate,
+  so their visual representation can have \a loops. This is realized by introducing a third
+  coordinate \a t, which defines the order of the points described by the other two coordinates \a
+  x and \a y.
+
+  To plot data, assign it with the \ref setData or \ref addData functions. Alternatively, you can
+  also access and modify the curve's data via the \ref data method, which returns a pointer to the
+  internal \ref QCPCurveDataContainer.
+  
+  Gaps in the curve can be created by adding data points with NaN as key and value
+  (<tt>qQNaN()</tt> or <tt>std::numeric_limits<double>::quiet_NaN()</tt>) in between the two data points that shall be
+  separated.
+  
+  \section qcpcurve-appearance Changing the appearance
+  
+  The appearance of the curve is determined by the pen and the brush (\ref setPen, \ref setBrush).
+  
+  \section qcpcurve-usage Usage
+  
+  Like all data representing objects in QCustomPlot, the QCPCurve is a plottable
+  (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
+  (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
+  
+  Usually, you first create an instance:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcurve-creation-1
+  which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot instance takes
+  ownership of the plottable, so do not delete it manually but use QCustomPlot::removePlottable() instead.
+  The newly created plottable can be modified, e.g.:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcurve-creation-2

+  printed to the debug output (qDebug), the construction is not aborted, though.

+  The created QCPCurve is automatically registered with the QCustomPlot instance inferred from \a

+  \brief Groups multiple QCPBars together so they appear side by side
+  
+  \image html QCPBarsGroup.png
+  
+  When showing multiple QCPBars in one plot which have bars at identical keys, it may be desirable
+  to have them appearing next to each other at each key. This is what adding the respective QCPBars
+  plottables to a QCPBarsGroup achieves. (An alternative approach is to stack them on top of each
+  other, see \ref QCPBars::moveAbove.)
+  
+  \section qcpbarsgroup-usage Usage
+  
+  To add a QCPBars plottable to the group, create a new group and then add the respective bars
+  intances:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpbarsgroup-creation
+  Alternatively to appending to the group like shown above, you can also set the group on the
+  QCPBars plottable via \ref QCPBars::setBarsGroup.
+  
+  The spacing between the bars can be configured via \ref setSpacingType and \ref setSpacing. The
+  bars in this group appear in the plot in the order they were appended. To insert a bars plottable
+  at a certain index position, or to reposition a bars plottable which is already in the group, use
+  \ref insert.
+  
+  To remove specific bars from the group, use either \ref remove or call \ref
+  QCPBars::setBarsGroup "QCPBars::setBarsGroup(0)" on the respective bars plottable.
+  
+  To clear the entire group, call \ref clear, or simply delete the group.

+/*! \class QCPStatisticalBox
+  \brief A plottable representing a single statistical box in a plot.
+
+  \image html QCPStatisticalBox.png
+  
+  To plot data, assign it with the \ref setData or \ref addData functions. Alternatively, you can
+  also access and modify the data via the \ref data method, which returns a pointer to the internal
+  \ref QCPStatisticalBoxDataContainer.
+  
+  Additionally each data point can itself have a list of outliers, drawn as scatter points at the
+  key coordinate of the respective statistical box data point. They can either be set by using the
+  respective \ref addData(double,double,double,double,double,double,const QVector<double>&)
+  "addData" method or accessing the individual data points through \ref data, and setting the
+  <tt>QVector<double> outliers</tt> of the data points directly.
+  
+  \section qcpstatisticalbox-appearance Changing the appearance
+  
+  The appearance of each data point box, ranging from the lower to the upper quartile, is
+  controlled via \ref setPen and \ref setBrush. You may change the width of the boxes with \ref
+  setWidth in plot coordinates.
+
+  Each data point's visual representation also consists of two whiskers. Whiskers are the lines
+  which reach from the upper quartile to the maximum, and from the lower quartile to the minimum.
+  The appearance of the whiskers can be modified with: \ref setWhiskerPen, \ref setWhiskerBarPen,
+  \ref setWhiskerWidth. The whisker width is the width of the bar perpendicular to the whisker at
+  the top (for maximum) and bottom (for minimum). If the whisker pen is changed, make sure to set
+  the \c capStyle to \c Qt::FlatCap. Otherwise the backbone line might exceed the whisker bars by a
+  few pixels due to the pen cap being not perfectly flat.
+  
+  The median indicator line inside the box has its own pen, \ref setMedianPen.
+  
+  The outlier data points are drawn as normal scatter points. Their look can be controlled with
+  \ref setOutlierStyle
+  
+  \section qcpstatisticalbox-usage Usage
+  
+  Like all data representing objects in QCustomPlot, the QCPStatisticalBox is a plottable
+  (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
+  (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
+  
+  Usually, you first create an instance:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpstatisticalbox-creation-1
+  which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot instance takes
+  ownership of the plottable, so do not delete it manually but use QCustomPlot::removePlottable() instead.
+  The newly created plottable can be modified, e.g.:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpstatisticalbox-creation-2

+
+/* start documentation of inline functions */
+
+/*! \fn QSharedPointer<QCPStatisticalBoxDataContainer> QCPStatisticalBox::data() const
+  
+  Returns a shared pointer to the internal data storage of type \ref
+  QCPStatisticalBoxDataContainer. You may use it to directly manipulate the data, which may be more
+  convenient and faster than using the regular \ref setData or \ref addData methods.

+  not have the same orientation. If either of these restrictions is violated, a corresponding
+  message is printed to the debug output (qDebug), the construction is not aborted, though.

+  The created QCPStatisticalBox is automatically registered with the QCustomPlot instance inferred

+/*! \class QCPColorMapData
+  \brief Holds the two-dimensional data of a QCPColorMap plottable.
+  
+  This class is a data storage for \ref QCPColorMap. It holds a two-dimensional array, which \ref
+  QCPColorMap then displays as a 2D image in the plot, where the array values are represented by a
+  color, depending on the value.
+  
+  The size of the array can be controlled via \ref setSize (or \ref setKeySize, \ref setValueSize).
+  Which plot coordinates these cells correspond to can be configured with \ref setRange (or \ref
+  setKeyRange, \ref setValueRange).
+  
+  The data cells can be accessed in two ways: They can be directly addressed by an integer index
+  with \ref setCell. This is the fastest method. Alternatively, they can be addressed by their plot
+  coordinate with \ref setData. plot coordinate to cell index transformations and vice versa are
+  provided by the functions \ref coordToCell and \ref cellToCoord.
+  
+  A \ref QCPColorMapData also holds an on-demand two-dimensional array of alpha values which (if
+  allocated) has the same size as the data map. It can be accessed via \ref setAlpha, \ref
+  fillAlpha and \ref clearAlpha. The memory for the alpha map is only allocated if needed, i.e. on
+  the first call of \ref setAlpha. \ref clearAlpha restores full opacity and frees the alpha map.
+  
+  This class also buffers the minimum and maximum values that are in the data set, to provide
+  QCPColorMap::rescaleDataRange with the necessary information quickly. Setting a cell to a value
+  that is greater than the current maximum increases this maximum to the new value. However,
+  setting the cell that currently holds the maximum value to a smaller value doesn't decrease the
+  maximum again, because finding the true new maximum would require going through the entire data
+  array, which might be time consuming. The same holds for the data minimum. This functionality is
+  given by \ref recalculateDataBounds, such that you can decide when it is sensible to find the
+  true current minimum and maximum. The method QCPColorMap::rescaleDataRange offers a convenience
+  parameter \a recalculateDataBounds which may be set to true to automatically call \ref
+  recalculateDataBounds internally.

+
+  \image html QCPColorMap.png
+  
+  The data is stored in the class \ref QCPColorMapData, which can be accessed via the data()
+  method.
+  
+  A color map has three dimensions to represent a data point: The \a key dimension, the \a value
+  dimension and the \a data dimension. As with other plottables such as graphs, \a key and \a value
+  correspond to two orthogonal axes on the QCustomPlot surface that you specify in the QCPColorMap
+  constructor. The \a data dimension however is encoded as the color of the point at (\a key, \a
+  value).
+
+  Set the number of points (or \a cells) in the key/value dimension via \ref
+  QCPColorMapData::setSize. The plot coordinate range over which these points will be displayed is
+  specified via \ref QCPColorMapData::setRange. The first cell will be centered on the lower range
+  boundary and the last cell will be centered on the upper range boundary. The data can be set by
+  either accessing the cells directly with QCPColorMapData::setCell or by addressing the cells via
+  their plot coordinates with \ref QCPColorMapData::setData. If possible, you should prefer
+  setCell, since it doesn't need to do any coordinate transformation and thus performs a bit
+  better.
+  
+  The cell with index (0, 0) is at the bottom left, if the color map uses normal (i.e. not reversed)
+  key and value axes.
+  
+  To show the user which colors correspond to which \a data values, a \ref QCPColorScale is
+  typically placed to the right of the axis rect. See the documentation there for details on how to
+  add and use a color scale.

+  The central part of the appearance is the color gradient, which can be specified via \ref
+  setGradient. See the documentation of \ref QCPColorGradient for details on configuring a color
+  gradient.
+  
+  The \a data range that is mapped to the colors of the gradient can be specified with \ref
+  setDataRange. To make the data range encompass the whole data set minimum to maximum, call \ref
+  rescaleDataRange.
+  
+  \section qcpcolormap-transparency Transparency
+  
+  Transparency in color maps can be achieved by two mechanisms. On one hand, you can specify alpha
+  values for color stops of the \ref QCPColorGradient, via the regular QColor interface. This will
+  cause the color map data which gets mapped to colors around those color stops to appear with the
+  accordingly interpolated transparency.
+  
+  On the other hand you can also directly apply an alpha value to each cell independent of its
+  data, by using the alpha map feature of \ref QCPColorMapData. The relevant methods are \ref
+  QCPColorMapData::setAlpha, QCPColorMapData::fillAlpha and \ref QCPColorMapData::clearAlpha().
+  
+  The two transparencies will be joined together in the plot and otherwise not interfere with each
+  other. They are mixed in a multiplicative matter, so an alpha of e.g. 50% (128/255) in both modes
+  simultaneously, will result in a total transparency of 25% (64/255).
+  
+  \section qcpcolormap-usage Usage
+  
+  Like all data representing objects in QCustomPlot, the QCPColorMap is a plottable
+  (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
+  (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
+  
+  Usually, you first create an instance:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolormap-creation-1
+  which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot instance takes
+  ownership of the plottable, so do not delete it manually but use QCustomPlot::removePlottable() instead.
+  The newly created plottable can be modified, e.g.:
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolormap-creation-2
+  
+  \note The QCPColorMap always displays the data at equal key/value intervals, even if the key or
+  value axis is set to a logarithmic scaling. If you want to use QCPColorMap with logarithmic axes,
+  you shouldn't use the \ref QCPColorMapData::setData method as it uses a linear transformation to
+  determine the cell index. Rather directly access the cell index with \ref
+  QCPColorMapData::setCell.

+/*! \class QCPFinancial
+  \brief A plottable representing a financial stock chart
+
+  \image html QCPFinancial.png
+
+  This plottable represents time series data binned to certain intervals, mainly used for stock
+  charts. The two common representations OHLC (Open-High-Low-Close) bars and Candlesticks can be
+  set via \ref setChartStyle.
+
+  The data is passed via \ref setData as a set of open/high/low/close values at certain keys
+  (typically times). This means the data must be already binned appropriately. If data is only
+  available as a series of values (e.g. \a price against \a time), you can use the static
+  convenience function \ref timeSeriesToOhlc to generate binned OHLC-data which can then be passed
+  to \ref setData.
+
+  The width of the OHLC bars/candlesticks can be controlled with \ref setWidth and \ref
+  setWidthType. A typical choice is to set the width type to \ref wtPlotCoords (the default) and
+  the width to (or slightly less than) one time bin interval width.
+
+  \section qcpfinancial-appearance Changing the appearance
+
+  Charts can be either single- or two-colored (\ref setTwoColored). If set to be single-colored,
+  lines are drawn with the plottable's pen (\ref setPen) and fills with the brush (\ref setBrush).
+
+  If set to two-colored, positive changes of the value during an interval (\a close >= \a open) are
+  represented with a different pen and brush than negative changes (\a close < \a open). These can
+  be configured with \ref setPenPositive, \ref setPenNegative, \ref setBrushPositive, and \ref
+  setBrushNegative. In two-colored mode, the normal plottable pen/brush is ignored. Upon selection
+  however, the normal selected pen/brush (provided by the \ref selectionDecorator) is used,
+  irrespective of whether the chart is single- or two-colored.
+
+  \section qcpfinancial-usage Usage
+
+  Like all data representing objects in QCustomPlot, the QCPFinancial is a plottable
+  (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
+  (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
+
+  Usually, you first create an instance:
+
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpfinancial-creation-1
+  which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot
+  instance takes ownership of the plottable, so do not delete it manually but use
+  QCustomPlot::removePlottable() instead. The newly created plottable can be modified, e.g.:
+
+  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpfinancial-creation-2
+  Here we have used the static helper method \ref timeSeriesToOhlc, to turn a time-price data
+  series into a 24-hour binned open-high-low-close data series as QCPFinancial uses.

+  printed to the debug output (qDebug), the construction is not aborted, though.

+  \brief A plottable that adds a set of error bars to other plottables.
+
+  \image html QCPErrorBars.png
+
+  The \ref QCPErrorBars plottable can be attached to other one-dimensional plottables (e.g. \ref
+  QCPGraph, \ref QCPCurve, \ref QCPBars, etc.) and equips them with error bars.
+
+  Use \ref setDataPlottable to define for which plottable the \ref QCPErrorBars shall display the
+  error bars. The orientation of the error bars can be controlled with \ref setErrorType.
+
+  By using \ref setData, you can supply the actual error data, either as symmetric error or
+  plus/minus asymmetric errors. \ref QCPErrorBars only stores the error data. The absolute
+  key/value position of each error bar will be adopted from the configured data plottable. The
+  error data of the \ref QCPErrorBars are associated one-to-one via their index to the data points
+  of the data plottable. You can directly access and manipulate the error bar data via \ref data.
+
+  Set either of the plus/minus errors to NaN (<tt>qQNaN()</tt> or
+  <tt>std::numeric_limits<double>::quiet_NaN()</tt>) to not show the respective error bar on the data point at
+  that index.
+
+  \section qcperrorbars-appearance Changing the appearance
+
+  The appearance of the error bars is defined by the pen (\ref setPen), and the width of the
+  whiskers (\ref setWhiskerWidth). Further, the error bar backbones may leave a gap around the data
+  point center to prevent that error bars are drawn too close to or even through scatter points.
+  This gap size can be controlled via \ref setSymbolGap.

+  the coordinate axes of the graph and update its \a position to be on the graph's data. This means
+  the key stays controllable via \ref setGraphKey, but the value will follow the graph data. If a
+  QCPGraph is connected, note that setting the coordinates of the tracer item directly via \a
+  position will have no effect because they will be overriden in the next redraw (this is when the
+  coordinate update happens).
+  
+  If the specified key in \ref setGraphKey is outside the key bounds of the graph, the tracer will
+  stay at the corresponding end of the graph.
+  
+  With \ref setInterpolating you may specify whether the tracer may only stay exactly on data
+  points or whether it interpolates data points linearly, if given a key that lies between two data
+  points of the graph.
+  
+  The tracer has different visual styles, see \ref setStyle. It is also possible to make the tracer
+  have no own visual appearance (set the style to \ref tsNone), and just connect other item
+  positions to the tracer \a position (used as an anchor) via \ref
+  QCPItemPosition::setParentAnchor.
+  
+  \note The tracer position is only automatically updated upon redraws. So when the data of the
+  graph changes and immediately afterwards (without a redraw) the position coordinates of the
+  tracer are retrieved, they will not reflect the updated data of the graph. In this case \ref
+  updatePosition must be called manually, prior to reading the tracer coordinates.

+    \class QSqlTableModel
+    \brief The QSqlTableModel class provides an editable data model
+    for a single database table.
+
+    \ingroup database
+    \inmodule QtSql
+
+    QSqlTableModel is a high-level interface for reading and writing
+    database records from a single table. It is built on top of the
+    lower-level QSqlQuery and can be used to provide data to view
+    classes such as QTableView. For example:
+
+    \snippet sqldatabase/sqldatabase.cpp 24
+
+    We set the SQL table's name and the edit strategy, then we set up
+    the labels displayed in the view header. The edit strategy
+    dictates when the changes done by the user in the view are
+    actually applied to the database. The possible values are \l
+    OnFieldChange, \l OnRowChange, and \l OnManualSubmit.
+
+    QSqlTableModel can also be used to access a database
+    programmatically, without binding it to a view:
+
+    \snippet sqldatabase/sqldatabase.cpp 21
+
+    The code snippet above extracts the \c salary field from record 4 in
+    the result set of the query \c{SELECT * from employee}.
+
+    It is possible to set filters using setFilter(), or modify the
+    sort order using setSort(). At the end, you must call select() to
+    populate the model with data.
+
+    The \l{tablemodel} example illustrates how to use
+    QSqlTableModel as the data source for a QTableView.
+
+    QSqlTableModel provides no direct support for foreign keys. Use
+    the QSqlRelationalTableModel and QSqlRelationalDelegate if you
+    want to resolve foreign keys.

+    \class QSqlDatabase
+    \brief The QSqlDatabase class represents a connection to
+    a database.
+
+    \ingroup database
+
+    \inmodule QtSql
+
+    The QSqlDatabase class provides an interface for accessing a
+    database through a connection. An instance of QSqlDatabase
+    represents the connection. The connection provides access to the
+    database via one of the \l{SQL Database Drivers#Supported
+    Databases} {supported database drivers}, which are derived from
+    QSqlDriver.  Alternatively, you can subclass your own database
+    driver from QSqlDriver. See \l{How to Write Your Own Database
+    Driver} for more information.
+
+    Create a connection (i.e., an instance of QSqlDatabase) by calling
+    one of the static addDatabase() functions, where you specify
+    \l{SQL Database Drivers#Supported Databases} {the driver or type
+    of driver} to use (i.e., what kind of database will you access?)
+    and a connection name. A connection is known by its own name,
+    \e{not} by the name of the database it connects to. You can have
+    multiple connections to one database. QSqlDatabase also supports
+    the concept of a \e{default} connection, which is the unnamed
+    connection. To create the default connection, don't pass the
+    connection name argument when you call addDatabase().
+    Subsequently, when you call any static member function that takes
+    the connection name argument, if you don't pass the connection
+    name argument, the default connection is assumed. The following
+    snippet shows how to create and open a default connection to a
+    PostgreSQL database:
+
+    \snippet sqldatabase/sqldatabase.cpp 0
+
+    Once the QSqlDatabase object has been created, set the connection
+    parameters with setDatabaseName(), setUserName(), setPassword(),
+    setHostName(), setPort(), and setConnectOptions(). Then call
+    open() to activate the physical connection to the database. The
+    connection is not usable until you open it.
+
+    The connection defined above will be the \e{default} connection,
+    because we didn't give a connection name to \l{QSqlDatabase::}
+    {addDatabase()}. Subsequently, you can get the default connection
+    by calling database() without the connection name argument:
+
+    \snippet sqldatabase/sqldatabase.cpp 1
+
+    QSqlDatabase is a value class. Changes made to a database
+    connection via one instance of QSqlDatabase will affect other
+    instances of QSqlDatabase that represent the same connection. Use
+    cloneDatabase() to create an independent database connection based
+    on an existing one.
+
+    If you create multiple database connections, specify a unique
+    connection name for each one, when you call addDatabase(). Use
+    database() with a connection name to get that connection. Use
+    removeDatabase() with a connection name to remove a connection.
+    QSqlDatabase outputs a warning if you try to remove a connection
+    referenced by other QSqlDatabase objects. Use contains() to see if
+    a given connection name is in the list of connections.
+
+    Once a connection is established, you can call tables() to get the
+    list of tables in the database, call primaryIndex() to get a
+    table's primary index, and call record() to get meta-information
+    about a table's fields (e.g., field names).
+
+    \note QSqlDatabase::exec() is deprecated. Use QSqlQuery::exec()
+    instead.
+
+    If the driver supports transactions, use transaction() to start a
+    transaction, and commit() or rollback() to complete it. Use
+    \l{QSqlDriver::} {hasFeature()} to ask if the driver supports
+    transactions. \note When using transactions, you must start the
+    transaction before you create your query.
+
+    If an error occurs, lastError() will return information about it.
+
+    Get the names of the available SQL drivers with drivers().  Check
+    for the presence of a particular driver with isDriverAvailable().
+    If you have created your own custom driver, you must register it
+    with registerSqlDriver().

+
+    This overload is useful when you want to create a database
+    connection with a \l{QSqlDriver} {driver} you instantiated
+    yourself. It might be your own database driver, or you might just
+    need to instantiate one of the Qt drivers yourself. If you do
+    this, it is recommended that you include the driver code in your
+    application. For example, you can create a PostgreSQL connection
+    with your own QPSQL driver like this:
+
+    \snippet code/src_sql_kernel_qsqldatabase.cpp 5
+    \codeline
+    \snippet code/src_sql_kernel_qsqldatabase.cpp 6
+
+    The above code sets up a PostgreSQL connection and instantiates a
+    QPSQLDriver object. Next, addDatabase() is called to add the
+    connection to the known connections so that it can be used by the
+    Qt SQL classes. When a driver is instantiated with a connection
+    handle (or set of handles), Qt assumes that you have already
+    opened the database connection.
+
+    \note We assume that \c qtdir is the directory where Qt is
+    installed. This will pull in the code that is needed to use the
+    PostgreSQL client library and to instantiate a QPSQLDriver object,
+    assuming that you have the PostgreSQL headers somewhere in your
+    include search path.
+
+    Remember that you must link your application against the database
+    client library. Make sure the client library is in your linker's
+    search path, and add lines like these to your \c{.pro} file:
+
+    \snippet code/src_sql_kernel_qsqldatabase.cpp 7
+
+    The method described works for all the supplied drivers.  The only
+    difference will be in the driver constructor arguments.  Here is a
+    table of the drivers included with Qt, their source code files,
+    and their constructor arguments:
+
+    \table
+    \header \li Driver \li Class name \li Constructor arguments \li File to include
+    \row

+    \li QPSQLDriver
+    \li PGconn *connection
+    \li \c qsql_psql.cpp
+    \row
+    \li QMYSQL
+    \li QMYSQLDriver
+    \li MYSQL *connection

+    \li QOCIDriver
+    \li OCIEnv *environment, OCISvcCtx *serviceContext
+    \li \c qsql_oci.cpp
+    \row
+    \li QODBC
+    \li QODBCDriver
+    \li SQLHANDLE environment, SQLHANDLE connection
+    \li \c qsql_odbc.cpp
+    \row

+
+    The host name (or service name) is needed when constructing the

+/*!
+    \class QSqlQueryModel
+    \brief The QSqlQueryModel class provides a read-only data model for SQL
+    result sets.
+
+    \ingroup database
+    \inmodule QtSql
+
+    QSqlQueryModel is a high-level interface for executing SQL
+    statements and traversing the result set. It is built on top of
+    the lower-level QSqlQuery and can be used to provide data to
+    view classes such as QTableView. For example:
+
+    \snippet sqldatabase/sqldatabase.cpp 16
+
+    We set the model's query, then we set up the labels displayed in
+    the view header.
+
+    QSqlQueryModel can also be used to access a database
+    programmatically, without binding it to a view:
+
+    \snippet sqldatabase/sqldatabase.cpp 21
+
+    The code snippet above extracts the \c salary field from record 4 in
+    the result set of the query \c{SELECT * from employee}. Assuming
+    that \c salary is column 2, we can rewrite the last line as follows:
+
+    \snippet sqldatabase/sqldatabase.cpp 22
+
+    The model is read-only by default. To make it read-write, you
+    must subclass it and reimplement setData() and flags(). Another
+    option is to use QSqlTableModel, which provides a read-write
+    model based on a single database table.
+
+    The \l{querymodel} example illustrates how to use
+    QSqlQueryModel to display the result of a query. It also shows
+    how to subclass QSqlQueryModel to customize the contents of the
+    data before showing it to the user, and how to create a
+    read-write model based on QSqlQueryModel.
+
+    If the database doesn't return the number of selected rows in
+    a query, the model will fetch rows incrementally.
+    See fetchMore() for more information.

+    \class QSqlQuery
+    \brief The QSqlQuery class provides a means of executing and
+    manipulating SQL statements.
+
+    \ingroup database
+    \ingroup shared
+
+    \inmodule QtSql
+
+    QSqlQuery encapsulates the functionality involved in creating,
+    navigating and retrieving data from SQL queries which are
+    executed on a \l QSqlDatabase. It can be used to execute DML
+    (data manipulation language) statements, such as \c SELECT, \c
+    INSERT, \c UPDATE and \c DELETE, as well as DDL (data definition
+    language) statements, such as \c{CREATE} \c{TABLE}. It can also
+    be used to execute database-specific commands which are not
+    standard SQL (e.g. \c{SET DATESTYLE=ISO} for PostgreSQL).
+
+    Successfully executed SQL statements set the query's state to
+    active so that isActive() returns \c true. Otherwise the query's
+    state is set to inactive. In either case, when executing a new SQL
+    statement, the query is positioned on an invalid record. An active
+    query must be navigated to a valid record (so that isValid()
+    returns \c true) before values can be retrieved.
+
+    For some databases, if an active query that is a \c{SELECT}
+    statement exists when you call \l{QSqlDatabase::}{commit()} or
+    \l{QSqlDatabase::}{rollback()}, the commit or rollback will
+    fail. See isActive() for details.
+
+    \target QSqlQuery examples
+
+    Navigating records is performed with the following functions:
+
+    \list
+    \li next()
+    \li previous()
+    \li first()
+    \li last()
+    \li seek()
+    \endlist
+
+    These functions allow the programmer to move forward, backward
+    or arbitrarily through the records returned by the query. If you
+    only need to move forward through the results (e.g., by using
+    next()), you can use setForwardOnly(), which will save a
+    significant amount of memory overhead and improve performance on
+    some databases. Once an active query is positioned on a valid
+    record, data can be retrieved using value(). All data is
+    transferred from the SQL backend using QVariants.
+
+    For example:
+
+    \snippet sqldatabase/sqldatabase.cpp 7
+
+    To access the data returned by a query, use value(int). Each
+    field in the data returned by a \c SELECT statement is accessed
+    by passing the field's position in the statement, starting from
+    0. This makes using \c{SELECT *} queries inadvisable because the
+    order of the fields returned is indeterminate.
+
+    For the sake of efficiency, there are no functions to access a
+    field by name (unless you use prepared queries with names, as
+    explained below). To convert a field name into an index, use
+    record().\l{QSqlRecord::indexOf()}{indexOf()}, for example:
+
+    \snippet sqldatabase/sqldatabase.cpp 8
+
+    QSqlQuery supports prepared query execution and the binding of
+    parameter values to placeholders. Some databases don't support
+    these features, so for those, Qt emulates the required
+    functionality. For example, the Oracle and ODBC drivers have
+    proper prepared query support, and Qt makes use of it; but for
+    databases that don't have this support, Qt implements the feature
+    itself, e.g. by replacing placeholders with actual values when a
+    query is executed. Use numRowsAffected() to find out how many rows
+    were affected by a non-\c SELECT query, and size() to find how
+    many were retrieved by a \c SELECT.
+
+    Oracle databases identify placeholders by using a colon-name
+    syntax, e.g \c{:name}. ODBC simply uses \c ? characters. Qt
+    supports both syntaxes, with the restriction that you can't mix
+    them in the same query.
+
+    You can retrieve the values of all the fields in a single variable
+    (a map) using boundValues().
+
+    \section1 Approaches to Binding Values
+
+    Below we present the same example using each of the four
+    different binding approaches, as well as one example of binding
+    values to a stored procedure.
+
+    \b{Named binding using named placeholders:}
+
+    \snippet sqldatabase/sqldatabase.cpp 9
+
+    \b{Positional binding using named placeholders:}
+
+    \snippet sqldatabase/sqldatabase.cpp 10
+
+    \b{Binding values using positional placeholders (version 1):}
+
+    \snippet sqldatabase/sqldatabase.cpp 11
+
+    \b{Binding values using positional placeholders (version 2):}
+
+    \snippet sqldatabase/sqldatabase.cpp 12
+
+    \b{Binding values to a stored procedure:}
+
+    This code calls a stored procedure called \c AsciiToInt(), passing
+    it a character through its in parameter, and taking its result in
+    the out parameter.
+
+    \snippet sqldatabase/sqldatabase.cpp 13
+
+    Note that unbound parameters will retain their values.
+
+    Stored procedures that uses the return statement to return values,
+    or return multiple result sets, are not fully supported. For specific
+    details see \l{SQL Database Drivers}.
+
+    \warning You must load the SQL driver and open the connection before a
+    QSqlQuery is created. Also, the connection must remain open while the
+    query exists; otherwise, the behavior of QSqlQuery is undefined.

+  parameters have to be lists of variants. If the database doesn't
+  support batch executions, the driver will simulate it using

+  Returns \c true if the query is executed successfully; otherwise
+  returns \c false.
+
+  Example:
+
+  \snippet code/src_sql_kernel_qsqlquery.cpp 2
+
+  The example above inserts four new rows into \c myTable:
+
+  \snippet code/src_sql_kernel_qsqlquery.cpp 3
+
+  To bind NULL values, a null QVariant of the relevant type has to be
+  added to the bound QVariantList; for example, \c
+  {QVariant(QVariant::String)} should be used if you are using
+  strings.
+
+  \note Every bound QVariantList must contain the same amount of
+  variants.
+
+  \note The type of the QVariants in a list must not change. For
+  example, you cannot mix integer and string variants within a
+  QVariantList.
+
+  The \a mode parameter indicates how the bound QVariantList will be
+  interpreted.  If \a mode is \c ValuesAsRows, every variant within
+  the QVariantList will be interpreted as a value for a new row. \c
+  ValuesAsColumns is a special case for the Oracle driver. In this
+  mode, every entry within a QVariantList will be interpreted as
+  array-value for an IN or OUT value within a stored procedure.  Note
+  that this will only work if the IN or OUT value is a table-type
+  consisting of only one column of a basic type, for example \c{TYPE

-    \class QSqlDatabase
-    \brief The QSqlDatabase class represents a connection to
-    a database.
-
-    \ingroup database
-
-    \inmodule QtSql
-
-    The QSqlDatabase class provides an interface for accessing a
-    database through a connection. An instance of QSqlDatabase
-    represents the connection. The connection provides access to the
-    database via one of the \l{SQL Database Drivers#Supported
-    Databases} {supported database drivers}, which are derived from
-    QSqlDriver.  Alternatively, you can subclass your own database
-    driver from QSqlDriver. See \l{How to Write Your Own Database
-    Driver} for more information.
-
-    Create a connection (i.e., an instance of QSqlDatabase) by calling
-    one of the static addDatabase() functions, where you specify
-    \l{SQL Database Drivers#Supported Databases} {the driver or type
-    of driver} to use (i.e., what kind of database will you access?)
-    and a connection name. A connection is known by its own name,
-    \e{not} by the name of the database it connects to. You can have
-    multiple connections to one database. QSqlDatabase also supports
-    the concept of a \e{default} connection, which is the unnamed
-    connection. To create the default connection, don't pass the
-    connection name argument when you call addDatabase().
-    Subsequently, when you call any static member function that takes
-    the connection name argument, if you don't pass the connection
-    name argument, the default connection is assumed. The following
-    snippet shows how to create and open a default connection to a
-    PostgreSQL database:
-
-    \snippet sqldatabase/sqldatabase.cpp 0
-
-    Once the QSqlDatabase object has been created, set the connection
-    parameters with setDatabaseName(), setUserName(), setPassword(),
-    setHostName(), setPort(), and setConnectOptions(). Then call
-    open() to activate the physical connection to the database. The
-    connection is not usable until you open it.
-
-    The connection defined above will be the \e{default} connection,
-    because we didn't give a connection name to \l{QSqlDatabase::}
-    {addDatabase()}. Subsequently, you can get the default connection
-    by calling database() without the connection name argument:
-
-    \snippet sqldatabase/sqldatabase.cpp 1
-
-    QSqlDatabase is a value class. Changes made to a database
-    connection via one instance of QSqlDatabase will affect other
-    instances of QSqlDatabase that represent the same connection. Use
-    cloneDatabase() to create an independent database connection based
-    on an existing one.
-
-    If you create multiple database connections, specify a unique
-    connection name for each one, when you call addDatabase(). Use
-    database() with a connection name to get that connection. Use
-    removeDatabase() with a connection name to remove a connection.
-    QSqlDatabase outputs a warning if you try to remove a connection
-    referenced by other QSqlDatabase objects. Use contains() to see if
-    a given connection name is in the list of connections.
-
-    Once a connection is established, you can call tables() to get the
-    list of tables in the database, call primaryIndex() to get a
-    table's primary index, and call record() to get meta-information
-    about a table's fields (e.g., field names).
-
-    \note QSqlDatabase::exec() is deprecated. Use QSqlQuery::exec()
-    instead.
-
-    If the driver supports transactions, use transaction() to start a
-    transaction, and commit() or rollback() to complete it. Use
-    \l{QSqlDriver::} {hasFeature()} to ask if the driver supports
-    transactions. \note When using transactions, you must start the
-    transaction before you create your query.
-
-    If an error occurs, lastError() will return information about it.
-
-    Get the names of the available SQL drivers with drivers().  Check
-    for the presence of a particular driver with isDriverAvailable().
-    If you have created your own custom driver, you must register it
-    with registerSqlDriver().

-/*! \fn QSqlDatabase QSqlDatabase::addDatabase(QSqlDriver* driver, const QString& connectionName)
-
-    This overload is useful when you want to create a database
-    connection with a \l{QSqlDriver} {driver} you instantiated
-    yourself. It might be your own database driver, or you might just
-    need to instantiate one of the Qt drivers yourself. If you do
-    this, it is recommended that you include the driver code in your
-    application. For example, you can create a PostgreSQL connection
-    with your own QPSQL driver like this:
-
-    \snippet code/src_sql_kernel_qsqldatabase.cpp 5
-    \codeline
-    \snippet code/src_sql_kernel_qsqldatabase.cpp 6
-
-    The above code sets up a PostgreSQL connection and instantiates a
-    QPSQLDriver object. Next, addDatabase() is called to add the
-    connection to the known connections so that it can be used by the
-    Qt SQL classes. When a driver is instantiated with a connection
-    handle (or set of handles), Qt assumes that you have already
-    opened the database connection.
-
-    \note We assume that \c qtdir is the directory where Qt is
-    installed. This will pull in the code that is needed to use the
-    PostgreSQL client library and to instantiate a QPSQLDriver object,
-    assuming that you have the PostgreSQL headers somewhere in your
-    include search path.
-
-    Remember that you must link your application against the database
-    client library. Make sure the client library is in your linker's
-    search path, and add lines like these to your \c{.pro} file:
-
-    \snippet code/src_sql_kernel_qsqldatabase.cpp 7
-
-    The method described works for all the supplied drivers.  The only
-    difference will be in the driver constructor arguments.  Here is a
-    table of the drivers included with Qt, their source code files,
-    and their constructor arguments:
-
-    \table
-    \header \li Driver \li Class name \li Constructor arguments \li File to include
-    \row
-    \li QPSQL
-    \li QPSQLDriver
-    \li PGconn *connection
-    \li \c qsql_psql.cpp
-    \row
-    \li QMYSQL
-    \li QMYSQLDriver
-    \li MYSQL *connection
-    \li \c qsql_mysql.cpp
-    \row
-    \li QOCI
-    \li QOCIDriver
-    \li OCIEnv *environment, OCISvcCtx *serviceContext
-    \li \c qsql_oci.cpp
-    \row
-    \li QODBC
-    \li QODBCDriver
-    \li SQLHANDLE environment, SQLHANDLE connection
-    \li \c qsql_odbc.cpp
-    \row
-    \li QDB2
-    \li QDB2
-    \li SQLHANDLE environment, SQLHANDLE connection

-
-    The host name (or service name) is needed when constructing the
-    QTDSDriver for creating new connections for internal queries. This
-    is to prevent blocking when several QSqlQuery objects are used
-    simultaneously.
-
-    \warning Adding a database connection with the same connection
-    name as an existing connection, causes the existing connection to
-    be replaced by the new one.

-    \class QSqlQuery
-    \brief The QSqlQuery class provides a means of executing and
-    manipulating SQL statements.
-
-    \ingroup database
-    \ingroup shared
-
-    \inmodule QtSql
-
-    QSqlQuery encapsulates the functionality involved in creating,
-    navigating and retrieving data from SQL queries which are
-    executed on a \l QSqlDatabase. It can be used to execute DML
-    (data manipulation language) statements, such as \c SELECT, \c
-    INSERT, \c UPDATE and \c DELETE, as well as DDL (data definition
-    language) statements, such as \c{CREATE} \c{TABLE}. It can also
-    be used to execute database-specific commands which are not
-    standard SQL (e.g. \c{SET DATESTYLE=ISO} for PostgreSQL).
-
-    Successfully executed SQL statements set the query's state to
-    active so that isActive() returns \c true. Otherwise the query's
-    state is set to inactive. In either case, when executing a new SQL
-    statement, the query is positioned on an invalid record. An active
-    query must be navigated to a valid record (so that isValid()
-    returns \c true) before values can be retrieved.
-
-    For some databases, if an active query that is a \c{SELECT}
-    statement exists when you call \l{QSqlDatabase::}{commit()} or
-    \l{QSqlDatabase::}{rollback()}, the commit or rollback will
-    fail. See isActive() for details.
-
-    \target QSqlQuery examples
-
-    Navigating records is performed with the following functions:
-
-    \list
-    \li next()
-    \li previous()
-    \li first()
-    \li last()
-    \li seek()
-    \endlist
-
-    These functions allow the programmer to move forward, backward
-    or arbitrarily through the records returned by the query. If you
-    only need to move forward through the results (e.g., by using
-    next()), you can use setForwardOnly(), which will save a
-    significant amount of memory overhead and improve performance on
-    some databases. Once an active query is positioned on a valid
-    record, data can be retrieved using value(). All data is
-    transferred from the SQL backend using QVariants.
-
-    For example:
-
-    \snippet sqldatabase/sqldatabase.cpp 7
-
-    To access the data returned by a query, use value(int). Each
-    field in the data returned by a \c SELECT statement is accessed
-    by passing the field's position in the statement, starting from
-    0. This makes using \c{SELECT *} queries inadvisable because the
-    order of the fields returned is indeterminate.
-
-    For the sake of efficiency, there are no functions to access a
-    field by name (unless you use prepared queries with names, as
-    explained below). To convert a field name into an index, use
-    record().\l{QSqlRecord::indexOf()}{indexOf()}, for example:
-
-    \snippet sqldatabase/sqldatabase.cpp 8
-
-    QSqlQuery supports prepared query execution and the binding of
-    parameter values to placeholders. Some databases don't support
-    these features, so for those, Qt emulates the required
-    functionality. For example, the Oracle and ODBC drivers have
-    proper prepared query support, and Qt makes use of it; but for
-    databases that don't have this support, Qt implements the feature
-    itself, e.g. by replacing placeholders with actual values when a
-    query is executed. Use numRowsAffected() to find out how many rows
-    were affected by a non-\c SELECT query, and size() to find how
-    many were retrieved by a \c SELECT.
-
-    Oracle databases identify placeholders by using a colon-name
-    syntax, e.g \c{:name}. ODBC simply uses \c ? characters. Qt
-    supports both syntaxes, with the restriction that you can't mix
-    them in the same query.
-
-    You can retrieve the values of all the fields in a single variable
-    (a map) using boundValues().
-
-    \section1 Approaches to Binding Values
-
-    Below we present the same example using each of the four
-    different binding approaches, as well as one example of binding
-    values to a stored procedure.
-
-    \b{Named binding using named placeholders:}
-
-    \snippet sqldatabase/sqldatabase.cpp 9
-
-    \b{Positional binding using named placeholders:}
-
-    \snippet sqldatabase/sqldatabase.cpp 10
-
-    \b{Binding values using positional placeholders (version 1):}
-
-    \snippet sqldatabase/sqldatabase.cpp 11
-
-    \b{Binding values using positional placeholders (version 2):}
-
-    \snippet sqldatabase/sqldatabase.cpp 12
-
-    \b{Binding values to a stored procedure:}
-
-    This code calls a stored procedure called \c AsciiToInt(), passing
-    it a character through its in parameter, and taking its result in
-    the out parameter.
-
-    \snippet sqldatabase/sqldatabase.cpp 13
-
-    Note that unbound parameters will retain their values.
-
-    Stored procedures that uses the return statement to return values,
-    or return multiple result sets, are not fully supported. For specific
-    details see \l{SQL Database Drivers}.
-
-    \warning You must load the SQL driver and open the connection before a
-    QSqlQuery is created. Also, the connection must remain open while the
-    query exists; otherwise, the behavior of QSqlQuery is undefined.

-    \class QSqlQueryModel
-    \brief The QSqlQueryModel class provides a read-only data model for SQL
-    result sets.
-
-    \ingroup database
-    \inmodule QtSql
-
-    QSqlQueryModel is a high-level interface for executing SQL
-    statements and traversing the result set. It is built on top of
-    the lower-level QSqlQuery and can be used to provide data to
-    view classes such as QTableView. For example:
-
-    \snippet sqldatabase/sqldatabase.cpp 16
-
-    We set the model's query, then we set up the labels displayed in
-    the view header.
-
-    QSqlQueryModel can also be used to access a database
-    programmatically, without binding it to a view:
-
-    \snippet sqldatabase/sqldatabase.cpp 21
-
-    The code snippet above extracts the \c salary field from record 4 in
-    the result set of the query \c{SELECT * from employee}. Assuming
-    that \c salary is column 2, we can rewrite the last line as follows:
-
-    \snippet sqldatabase/sqldatabase.cpp 22
-
-    The model is read-only by default. To make it read-write, you
-    must subclass it and reimplement setData() and flags(). Another
-    option is to use QSqlTableModel, which provides a read-write
-    model based on a single database table.
-
-    The \l{querymodel} example illustrates how to use
-    QSqlQueryModel to display the result of a query. It also shows
-    how to subclass QSqlQueryModel to customize the contents of the
-    data before showing it to the user, and how to create a
-    read-write model based on QSqlQueryModel.
-
-    If the database doesn't return the number of selected rows in
-    a query, the model will fetch rows incrementally.
-    See fetchMore() for more information.

-    \class QSqlTableModel
-    \brief The QSqlTableModel class provides an editable data model
-    for a single database table.
-
-    \ingroup database
-    \inmodule QtSql
-
-    QSqlTableModel is a high-level interface for reading and writing
-    database records from a single table. It is built on top of the
-    lower-level QSqlQuery and can be used to provide data to view
-    classes such as QTableView. For example:
-
-    \snippet sqldatabase/sqldatabase.cpp 24
-
-    We set the SQL table's name and the edit strategy, then we set up
-    the labels displayed in the view header. The edit strategy
-    dictates when the changes done by the user in the view are
-    actually applied to the database. The possible values are \l
-    OnFieldChange, \l OnRowChange, and \l OnManualSubmit.
-
-    QSqlTableModel can also be used to access a database
-    programmatically, without binding it to a view:
-
-    \snippet sqldatabase/sqldatabase.cpp 21
-
-    The code snippet above extracts the \c salary field from record 4 in
-    the result set of the query \c{SELECT * from employee}.
-
-    It is possible to set filters using setFilter(), or modify the
-    sort order using setSort(). At the end, you must call select() to
-    populate the model with data.
-
-    The \l{tablemodel} example illustrates how to use
-    QSqlTableModel as the data source for a QTableView.
-
-    QSqlTableModel provides no direct support for foreign keys. Use
-    the QSqlRelationalTableModel and QSqlRelationalDelegate if you
-    want to resolve foreign keys.

-  \brief The abstract base class for paint buffers, which define the rendering backend
-
-  This abstract base class defines the basic interface that a paint buffer needs to provide in
-  order to be usable by QCustomPlot.
-
-  A paint buffer manages both a surface to draw onto, and the matching paint device. The size of
-  the surface can be changed via \ref setSize. External classes (\ref QCustomPlot and \ref
-  QCPLayer) request a painter via \ref startPainting and then perform the draw calls. Once the
-  painting is complete, \ref donePainting is called, so the paint buffer implementation can do
-  clean up if necessary. Before rendering a frame, each paint buffer is usually filled with a color
-  using \ref clear (usually the color is \c Qt::transparent), to remove the contents of the
-  previous frame.
-
-  The simplest paint buffer implementation is \ref QCPPaintBufferPixmap which allows regular
-  software rendering via the raster engine. Hardware accelerated rendering via pixel buffers and
-  frame buffer objects is provided by \ref QCPPaintBufferGlPbuffer and \ref QCPPaintBufferGlFbo.
-  They are used automatically if \ref QCustomPlot::setOpenGl is enabled.

-/*! \class QCPLayer
-  \brief A layer that may contain objects, to control the rendering order
-
-  The Layering system of QCustomPlot is the mechanism to control the rendering order of the
-  elements inside the plot.
-
-  It is based on the two classes QCPLayer and QCPLayerable. QCustomPlot holds an ordered list of
-  one or more instances of QCPLayer (see QCustomPlot::addLayer, QCustomPlot::layer,
-  QCustomPlot::moveLayer, etc.). When replotting, QCustomPlot goes through the list of layers
-  bottom to top and successively draws the layerables of the layers into the paint buffer(s).
-
-  A QCPLayer contains an ordered list of QCPLayerable instances. QCPLayerable is an abstract base
-  class from which almost all visible objects derive, like axes, grids, graphs, items, etc.
-
-  \section qcplayer-defaultlayers Default layers
-
-  Initially, QCustomPlot has six layers: "background", "grid", "main", "axes", "legend" and
-  "overlay" (in that order). On top is the "overlay" layer, which only contains the QCustomPlot's
-  selection rect (\ref QCustomPlot::selectionRect). The next two layers "axes" and "legend" contain
-  the default axes and legend, so they will be drawn above plottables. In the middle, there is the
-  "main" layer. It is initially empty and set as the current layer (see
-  QCustomPlot::setCurrentLayer). This means, all new plottables, items etc. are created on this
-  layer by default. Then comes the "grid" layer which contains the QCPGrid instances (which belong
-  tightly to QCPAxis, see \ref QCPAxis::grid). The Axis rect background shall be drawn behind
-  everything else, thus the default QCPAxisRect instance is placed on the "background" layer. Of
-  course, the layer affiliation of the individual objects can be changed as required (\ref
-  QCPLayerable::setLayer).
-
-  \section qcplayer-ordering Controlling the rendering order via layers
-
-  Controlling the ordering of layerables in the plot is easy: Create a new layer in the position
-  you want the layerable to be in, e.g. above "main", with \ref QCustomPlot::addLayer. Then set the
-  current layer with \ref QCustomPlot::setCurrentLayer to that new layer and finally create the
-  objects normally. They will be placed on the new layer automatically, due to the current layer
-  setting. Alternatively you could have also ignored the current layer setting and just moved the
-  objects with \ref QCPLayerable::setLayer to the desired layer after creating them.
-
-  It is also possible to move whole layers. For example, If you want the grid to be shown in front
-  of all plottables/items on the "main" layer, just move it above "main" with
-  QCustomPlot::moveLayer.
-
-  The rendering order within one layer is simply by order of creation or insertion. The item
-  created last (or added last to the layer), is drawn on top of all other objects on that layer.
-
-  When a layer is deleted, the objects on it are not deleted with it, but fall on the layer below
-  the deleted layer, see QCustomPlot::removeLayer.
-
-  \section qcplayer-buffering Replotting only a specific layer
-
-  If the layer mode (\ref setMode) is set to \ref lmBuffered, you can replot only this specific
-  layer by calling \ref replot. In certain situations this can provide better replot performance,
-  compared with a full replot of all layers. Upon creation of a new layer, the layer mode is
-  initialized to \ref lmLogical. The only layer that is set to \ref lmBuffered in a new \ref
-  QCustomPlot instance is the "overlay" layer, containing the selection rect.

-  
-  This function applies the default antialiasing setting to the specified \a painter, using the
-  function \ref applyAntialiasingHint. It is the antialiasing state the painter is put in, when
-  \ref draw is called on the layerable. If the layerable has multiple entities whose antialiasing
-  setting may be specified individually, this function should set the antialiasing state of the
-  most prominent entity. In this case however, the \ref draw function usually calls the specialized
-  versions of this function before drawing each entity, effectively overriding the setting of the
-  default antialiasing hint.
-  
-  <b>First example:</b> QCPGraph has multiple entities that have an antialiasing setting: The graph
-  line, fills and scatters. Those can be configured via QCPGraph::setAntialiased,
-  QCPGraph::setAntialiasedFill and QCPGraph::setAntialiasedScatters. Consequently, there isn't only
-  the QCPGraph::applyDefaultAntialiasingHint function (which corresponds to the graph line's
-  antialiasing), but specialized ones like QCPGraph::applyFillAntialiasingHint and
-  QCPGraph::applyScattersAntialiasingHint. So before drawing one of those entities, QCPGraph::draw
-  calls the respective specialized applyAntialiasingHint function.
-  
-  <b>Second example:</b> QCPItemLine consists only of a line so there is only one antialiasing
-  setting which can be controlled with QCPItemLine::setAntialiased. (This function is inherited by
-  all layerables. The specialized functions, as seen on QCPGraph, must be added explicitly to the
-  respective layerable subclass.) Consequently it only has the normal
-  QCPItemLine::applyDefaultAntialiasingHint. The \ref QCPItemLine::draw function doesn't need to
-  care about setting any antialiasing states, because the default antialiasing hint is already set
-  on the painter when the \ref draw function is called, and that's the state it wants to draw the

-  This function is used to decide whether a click hits a layerable object or not.
-
-  \a pos is a point in pixel coordinates on the QCustomPlot surface. This function returns the
-  shortest pixel distance of this point to the object. If the object is either invisible or the
-  distance couldn't be determined, -1.0 is returned. Further, if \a onlySelectable is true and the
-  object is not selectable, -1.0 is returned, too.
-
-  If the object is represented not by single lines but by an area like a \ref QCPItemText or the
-  bars of a \ref QCPBars plottable, a click inside the area should also be considered a hit. In
-  these cases this function thus returns a constant value greater zero but still below the parent
-  plot's selection tolerance. (typically the selectionTolerance multiplied by 0.99).
-  
-  Providing a constant value for area objects allows selecting line objects even when they are
-  obscured by such area objects, by clicking close to the lines (i.e. closer than
-  0.99*selectionTolerance).
-  
-  The actual setting of the selection state is not done by this function. This is handled by the
-  parent QCustomPlot when the mouseReleaseEvent occurs, and the finally selected object is notified
-  via the \ref selectEvent/\ref deselectEvent methods.
-  
-  \a details is an optional output parameter. Every layerable subclass may place any information
-  in \a details. This information will be passed to \ref selectEvent when the parent QCustomPlot
-  decides on the basis of this selectTest call, that the object was successfully selected. The
-  subsequent call to \ref selectEvent will carry the \a details. This is useful for multi-part
-  objects (like QCPAxis). This way, a possibly complex calculation to decide which part was clicked
-  is only done once in \ref selectTest. The result (i.e. the actually clicked part) can then be
-  placed in \a details. So in the subsequent \ref selectEvent, the decision which part was
-  selected doesn't have to be done a second time for a single selection operation.
-  
-  You may pass 0 as \a details to indicate that you are not interested in those selection details.

-/*! \class QCPDataRange
-  \brief Describes a data range given by begin and end index
-  
-  QCPDataRange holds two integers describing the begin (\ref setBegin) and end (\ref setEnd) index
-  of a contiguous set of data points. The end index points to the data point above the last data point that's part of
-  the data range, similarly to the nomenclature used in standard iterators.
-  
-  Data Ranges are not bound to a certain plottable, thus they can be freely exchanged, created and
-  modified. If a non-contiguous data set shall be described, the class \ref QCPDataSelection is
-  used, which holds and manages multiple instances of \ref QCPDataRange. In most situations, \ref
-  QCPDataSelection is thus used.
-  
-  Both \ref QCPDataRange and \ref QCPDataSelection offer convenience methods to work with them,
-  e.g. \ref bounded, \ref expanded, \ref intersects, \ref intersection, \ref adjusted, \ref
-  contains. Further, addition and subtraction operators (defined in \ref QCPDataSelection) can be
-  used to join/subtract data ranges and data selections (or mixtures), to retrieve a corresponding
-  \ref QCPDataSelection.
-  
-  %QCustomPlot's \ref dataselection "data selection mechanism" is based on \ref QCPDataSelection and
-  QCPDataRange.
-  
-  \note Do not confuse \ref QCPDataRange with \ref QCPRange. A \ref QCPRange describes an interval
-  in floating point plot coordinates, e.g. the current axis range.

-/*! \class QCPDataSelection
-  \brief Describes a data set by holding multiple QCPDataRange instances
-  
-  QCPDataSelection manages multiple instances of QCPDataRange in order to represent any (possibly
-  disjoint) set of data selection.
-  
-  The data selection can be modified with addition and subtraction operators which take
-  QCPDataSelection and QCPDataRange instances, as well as methods such as \ref addDataRange and
-  \ref clear. Read access is provided by \ref dataRange, \ref dataRanges, \ref dataRangeCount, etc.
-  
-  The method \ref simplify is used to join directly adjacent or even overlapping QCPDataRange
-  instances. QCPDataSelection automatically simplifies when using the addition/subtraction
-  operators. The only case when \ref simplify is left to the user, is when calling \ref
-  addDataRange, with the parameter \a simplify explicitly set to false. This is useful if many data
-  ranges will be added to the selection successively and the overhead for simplifying after each
-  iteration shall be avoided. In this case, you should make sure to call \ref simplify after
-  completing the operation.
-  
-  Use \ref enforceType to bring the data selection into a state complying with the constraints for
-  selections defined in \ref QCP::SelectionType.
-  
-  %QCustomPlot's \ref dataselection "data selection mechanism" is based on QCPDataSelection and
-  QCPDataRange.

-/*! \class QCPSelectionRect
-  \brief Provides rect/rubber-band data selection and range zoom interaction
-  
-  QCPSelectionRect is used by QCustomPlot when the \ref QCustomPlot::setSelectionRectMode is not
-  \ref QCP::srmNone. When the user drags the mouse across the plot, the current selection rect
-  instance (\ref QCustomPlot::setSelectionRect) is forwarded these events and makes sure an
-  according rect shape is drawn. At the begin, during, and after completion of the interaction, it
-  emits the corresponding signals \ref started, \ref changed, \ref canceled, and \ref accepted.
-  
-  The QCustomPlot instance connects own slots to the current selection rect instance, in order to
-  react to an accepted selection rect interaction accordingly.
-  
-  \ref isActive can be used to check whether the selection rect is currently active. An ongoing
-  selection interaction can be cancelled programmatically via calling \ref cancel at any time.
-  
-  The appearance of the selection rect can be controlled via \ref setPen and \ref setBrush.
-
-  If you wish to provide custom behaviour, e.g. a different visual representation of the selection
-  rect (\ref QCPSelectionRect::draw), you can subclass QCPSelectionRect and pass an instance of
-  your subclass to \ref QCustomPlot::setSelectionRect.

-/*! \class QCPMarginGroup
-  \brief A margin group allows synchronization of margin sides if working with multiple layout elements.
-  
-  QCPMarginGroup allows you to tie a margin side of two or more layout elements together, such that
-  they will all have the same size, based on the largest required margin in the group.
-  
-  \n
-  \image html QCPMarginGroup.png "Demonstration of QCPMarginGroup"
-  \n
-  
-  In certain situations it is desirable that margins at specific sides are synchronized across
-  layout elements. For example, if one QCPAxisRect is below another one in a grid layout, it will
-  provide a cleaner look to the user if the left and right margins of the two axis rects are of the
-  same size. The left axis of the top axis rect will then be at the same horizontal position as the
-  left axis of the lower axis rect, making them appear aligned. The same applies for the right
-  axes. This is what QCPMarginGroup makes possible.
-  
-  To add/remove a specific side of a layout element to/from a margin group, use the \ref
-  QCPLayoutElement::setMarginGroup method. To completely break apart the margin group, either call
-  \ref clear, or just delete the margin group.
-  
-  \section QCPMarginGroup-example Example
-  
-  First create a margin group:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpmargingroup-creation-1
-  Then set this group on the layout element sides:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpmargingroup-creation-2
-  Here, we've used the first two axis rects of the plot and synchronized their left margins with
-  each other and their right margins with each other.

-/*! \class QCPLayoutElement
-  \brief The abstract base class for all objects that form \ref thelayoutsystem "the layout system".
-  
-  This is an abstract base class. As such, it can't be instantiated directly, rather use one of its subclasses.
-  
-  A Layout element is a rectangular object which can be placed in layouts. It has an outer rect
-  (QCPLayoutElement::outerRect) and an inner rect (\ref QCPLayoutElement::rect). The difference
-  between outer and inner rect is called its margin. The margin can either be set to automatic or
-  manual (\ref setAutoMargins) on a per-side basis. If a side is set to manual, that margin can be
-  set explicitly with \ref setMargins and will stay fixed at that value. If it's set to automatic,
-  the layout element subclass will control the value itself (via \ref calculateAutoMargin).
-  
-  Layout elements can be placed in layouts (base class QCPLayout) like QCPLayoutGrid. The top level
-  layout is reachable via \ref QCustomPlot::plotLayout, and is a \ref QCPLayoutGrid. Since \ref
-  QCPLayout itself derives from \ref QCPLayoutElement, layouts can be nested.
-  
-  Thus in QCustomPlot one can divide layout elements into two categories: The ones that are
-  invisible by themselves, because they don't draw anything. Their only purpose is to manage the
-  position and size of other layout elements. This category of layout elements usually use
-  QCPLayout as base class. Then there is the category of layout elements which actually draw
-  something. For example, QCPAxisRect, QCPLegend and QCPTextElement are of this category. This does
-  not necessarily mean that the latter category can't have child layout elements. QCPLegend for
-  instance, actually derives from QCPLayoutGrid and the individual legend items are child layout
-  elements in the grid layout.

-/*! \class QCPLayout
-  \brief The abstract base class for layouts
-  
-  This is an abstract base class for layout elements whose main purpose is to define the position
-  and size of other child layout elements. In most cases, layouts don't draw anything themselves
-  (but there are exceptions to this, e.g. QCPLegend).
-  
-  QCPLayout derives from QCPLayoutElement, and thus can itself be nested in other layouts.
-  
-  QCPLayout introduces a common interface for accessing and manipulating the child elements. Those
-  functions are most notably \ref elementCount, \ref elementAt, \ref takeAt, \ref take, \ref
-  simplify, \ref removeAt, \ref remove and \ref clear. Individual subclasses may add more functions
-  to this interface which are more specialized to the form of the layout. For example, \ref
-  QCPLayoutGrid adds functions that take row and column indices to access cells of the layout grid
-  more conveniently.
-  
-  Since this is an abstract base class, you can't instantiate it directly. Rather use one of its
-  subclasses like QCPLayoutGrid or QCPLayoutInset.
-  
-  For a general introduction to the layout system, see the dedicated documentation page \ref
-  thelayoutsystem "The Layout System".

-/*! \class QCPLayoutGrid
-  \brief A layout that arranges child elements in a grid
-
-  Elements are laid out in a grid with configurable stretch factors (\ref setColumnStretchFactor,
-  \ref setRowStretchFactor) and spacing (\ref setColumnSpacing, \ref setRowSpacing).
-
-  Elements can be added to cells via \ref addElement. The grid is expanded if the specified row or
-  column doesn't exist yet. Whether a cell contains a valid layout element can be checked with \ref
-  hasElement, that element can be retrieved with \ref element. If rows and columns that only have
-  empty cells shall be removed, call \ref simplify. Removal of elements is either done by just
-  adding the element to a different layout or by using the QCPLayout interface \ref take or \ref
-  remove.
-
-  If you use \ref addElement(QCPLayoutElement*) without explicit parameters for \a row and \a
-  column, the grid layout will choose the position according to the current \ref setFillOrder and
-  the wrapping (\ref setWrap).
-
-  Row and column insertion can be performed with \ref insertRow and \ref insertColumn.

-  For every ending a line-like item has, an instance of this class exists. For example, QCPItemLine
-  has two endings which can be set with QCPItemLine::setHead and QCPItemLine::setTail.
- 
-  The styles themselves are defined via the enum QCPLineEnding::EndingStyle. Most decorations can

-  the ending decoration (e.g. direction an arrow is pointing) is controlled by the line-like item.
-  For example, when both endings of a QCPItemLine are set to be arrows, they will point to opposite
-  directions, e.g. "outward". This can be changed by \ref setInverted, which would make the
-  respective arrow point inward.
-  
-  Note that due to the overloaded QCPLineEnding constructor, you may directly specify a

-/*! \class QCPAxisTicker
-  \brief The base class tick generator used by QCPAxis to create tick positions and tick labels
-  
-  Each QCPAxis has an internal QCPAxisTicker (or a subclass) in order to generate tick positions
-  and tick labels for the current axis range. The ticker of an axis can be set via \ref
-  QCPAxis::setTicker. Since that method takes a <tt>QSharedPointer<QCPAxisTicker></tt>, multiple
-  axes can share the same ticker instance.
-  
-  This base class generates normal tick coordinates and numeric labels for linear axes. It picks a
-  reasonable tick step (the separation between ticks) which results in readable tick labels. The
-  number of ticks that should be approximately generated can be set via \ref setTickCount.
-  Depending on the current tick step strategy (\ref setTickStepStrategy), the algorithm either
-  sacrifices readability to better match the specified tick count (\ref
-  QCPAxisTicker::tssMeetTickCount) or relaxes the tick count in favor of better tick steps (\ref
-  QCPAxisTicker::tssReadability), which is the default.
-  
-  The following more specialized axis ticker subclasses are available, see details in the
-  respective class documentation:

-  \section axisticker-subclassing Creating own axis tickers
-  
-  Creating own axis tickers can be achieved very easily by sublassing QCPAxisTicker and
-  reimplementing some or all of the available virtual methods.
-
-  In the simplest case you might wish to just generate different tick steps than the other tickers,
-  so you only reimplement the method \ref getTickStep. If you additionally want control over the
-  string that will be shown as tick label, reimplement \ref getTickLabel.
-  
-  If you wish to have complete control, you can generate the tick vectors and tick label vectors
-  yourself by reimplementing \ref createTickVector and \ref createLabelVector. The default
-  implementations use the previously mentioned virtual methods \ref getTickStep and \ref
-  getTickLabel, but your reimplementations don't necessarily need to do so. For example in the case
-  of unequal tick steps, the method \ref getTickStep loses its usefulness and can be ignored.
-  
-  The sub tick count between major ticks can be controlled with \ref getSubTickCount. Full sub tick
-  placement control is obtained by reimplementing \ref createSubTickVector.
-  
-  See the documentation of all these virtual methods in QCPAxisTicker for detailed information
-  about the parameters and expected return values.

-/*! \class QCPAxisTickerDateTime
-  \brief Specialized axis ticker for calendar dates and times as axis ticks
-  
-  \image html axisticker-datetime.png
-  
-  This QCPAxisTicker subclass generates ticks that correspond to real calendar dates and times. The
-  plot axis coordinate is interpreted as Unix Time, so seconds since Epoch (January 1, 1970, 00:00
-  UTC). This is also used for example by QDateTime in the <tt>toTime_t()/setTime_t()</tt> methods
-  with a precision of one second. Since Qt 4.7, millisecond accuracy can be obtained from QDateTime
-  by using <tt>QDateTime::fromMSecsSinceEpoch()/1000.0</tt>. The static methods \ref dateTimeToKey
-  and \ref keyToDateTime conveniently perform this conversion achieving a precision of one
-  millisecond on all Qt versions.
-  
-  The format of the date/time display in the tick labels is controlled with \ref setDateTimeFormat.
-  If a different time spec (time zone) shall be used, see \ref setDateTimeSpec.
-  
-  This ticker produces unequal tick spacing in order to provide intuitive date and time-of-day
-  ticks. For example, if the axis range spans a few years such that there is one tick per year,
-  ticks will be positioned on 1. January of every year. This is intuitive but, due to leap years,
-  will result in slightly unequal tick intervals (visually unnoticeable). The same can be seen in
-  the image above: even though the number of days varies month by month, this ticker generates
-  ticks on the same day of each month.
-  
-  If you would like to change the date/time that is used as a (mathematical) starting date for the
-  ticks, use the \ref setTickOrigin(const QDateTime &origin) method overload, which takes a
-  QDateTime. If you pass 15. July, 9:45 to this method, the yearly ticks will end up on 15. July at
-  9:45 of every year.
-  
-  The ticker can be created and assigned to an axis like this:
-  \snippet documentation/doc-image-generator/mainwindow.cpp axistickerdatetime-creation
-  
-  \note If you rather wish to display relative times in terms of days, hours, minutes, seconds and
-  milliseconds, and are not interested in the intricacies of real calendar dates with months and
-  (leap) years, have a look at QCPAxisTickerTime instead.

-  \brief Specialized axis ticker for time spans in units of milliseconds to days
-  
-  \image html axisticker-time.png
-  
-  This QCPAxisTicker subclass generates ticks that corresponds to time intervals.
-  
-  The format of the time display in the tick labels is controlled with \ref setTimeFormat and \ref
-  setFieldWidth. The time coordinate is in the unit of seconds with respect to the time coordinate
-  zero. Unlike with QCPAxisTickerDateTime, the ticks don't correspond to a specific calendar date
-  and time.
-  
-  The time can be displayed in milliseconds, seconds, minutes, hours and days. Depending on the
-  largest available unit in the format specified with \ref setTimeFormat, any time spans above will
-  be carried in that largest unit. So for example if the format string is "%m:%s" and a tick at
-  coordinate value 7815 (being 2 hours, 10 minutes and 15 seconds) is created, the resulting tick
-  label will show "130:15" (130 minutes, 15 seconds). If the format string is "%h:%m:%s", the hour
-  unit will be used and the label will thus be "02:10:15". Negative times with respect to the axis
-  zero will carry a leading minus sign.
-  
-  The ticker can be created and assigned to an axis like this:
-  \snippet documentation/doc-image-generator/mainwindow.cpp axistickertime-creation
-  
-  Here is an example of a time axis providing time information in days, hours and minutes. Due to
-  the axis range spanning a few days and the wanted tick count (\ref setTickCount), the ticker
-  decided to use tick steps of 12 hours:
-  
-  \image html axisticker-time2.png

-  \image html axisticker-log.png
-  
-  This QCPAxisTicker subclass generates ticks with unequal tick intervals suited for logarithmic
-  axis scales. The ticks are placed at powers of the specified log base (\ref setLogBase).
-  
-  Especially in the case of a log base equal to 10 (the default), it might be desirable to have
-  tick labels in the form of powers of ten without mantissa display. To achieve this, set the
-  number precision (\ref QCPAxis::setNumberPrecision) to zero and the number format (\ref
-  QCPAxis::setNumberFormat) to scientific (exponential) display with beautifully typeset decimal
-  powers, so a format string of <tt>"eb"</tt>. This will result in the following axis tick labels:
-

-  
-  \a formatCode is a string of one, two or three characters. The first character is identical to
-  the normal format code used by Qt. In short, this means: 'e'/'E' scientific format, 'f' fixed
-  format, 'g'/'G' scientific or fixed, whichever is shorter.
-  
-  The second and third characters are optional and specific to QCustomPlot:\n
-  If the first char was 'e' or 'g', numbers are/might be displayed in the scientific format, e.g.
-  "5.5e9", which is ugly in a plot. So when the second char of \a formatCode is set to 'b' (for
-  "beautiful"), those exponential numbers are formatted in a more natural way, i.e. "5.5
-  [multiplication sign] 10 [superscript] 9". By default, the multiplication sign is a centered dot.
-  If instead a cross should be shown (as is usual in the USA), the third char of \a formatCode can
-  be set to 'c'. The inserted multiplication signs are the UTF-8 characters 215 (0xD7) for the
-  cross and 183 (0xB7) for the dot.
-  
-  Examples for \a formatCode:
-  \li \c g normal format code behaviour. If number is small, fixed format is used, if number is large,
-  normal scientific format is used
-  \li \c gb If number is small, fixed format is used, if number is large, scientific format is used with
-  beautifully typeset decimal powers and a dot as multiplication sign
-  \li \c ebc All numbers are in scientific format with beautifully typeset decimal power and a cross as
-  multiplication sign
-  \li \c fb illegal format code, since fixed format doesn't support (or need) beautifully typeset decimal
-  powers. Format code will be reduced to 'f'.
-  \li \c hello illegal format code, since first char is not 'e', 'E', 'f', 'g' or 'G'. Current format
-  code will not be changed.

-/*! \class QCPScatterStyle
-  \brief Represents the visual appearance of scatter points
-  
-  This class holds information about shape, color and size of scatter points. In plottables like
-  QCPGraph it is used to store how scatter points shall be drawn. For example, \ref
-  QCPGraph::setScatterStyle takes a QCPScatterStyle instance.
-  
-  A scatter style consists of a shape (\ref setShape), a line color (\ref setPen) and possibly a
-  fill (\ref setBrush), if the shape provides a fillable area. Further, the size of the shape can
-  be controlled with \ref setSize.
-
-  \section QCPScatterStyle-defining Specifying a scatter style
-  
-  You can set all these configurations either by calling the respective functions on an instance:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpscatterstyle-creation-1
-  
-  Or you can use one of the various constructors that take different parameter combinations, making
-  it easy to specify a scatter style in a single call, like so:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpscatterstyle-creation-2
-  
-  \section QCPScatterStyle-undefinedpen Leaving the color/pen up to the plottable
-  
-  There are two constructors which leave the pen undefined: \ref QCPScatterStyle() and \ref
-  QCPScatterStyle(ScatterShape shape, double size). If those constructors are used, a call to \ref
-  isPenDefined will return false. It leads to scatter points that inherit the pen from the
-  plottable that uses the scatter style. Thus, if such a scatter style is passed to QCPGraph, the line
-  color of the graph (\ref QCPGraph::setPen) will be used by the scatter points. This makes
-  it very convenient to set up typical scatter settings:
-  
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpscatterstyle-shortcreation
-
-  Notice that it wasn't even necessary to explicitly call a QCPScatterStyle constructor. This works
-  because QCPScatterStyle provides a constructor that can transform a \ref ScatterShape directly
-  into a QCPScatterStyle instance (that's the \ref QCPScatterStyle(ScatterShape shape, double size)
-  constructor with a default for \a size). In those cases, C++ allows directly supplying a \ref
-  ScatterShape, where actually a QCPScatterStyle is expected.
-  
-  \section QCPScatterStyle-custompath-and-pixmap Custom shapes and pixmaps
-  
-  QCPScatterStyle supports drawing custom shapes and arbitrary pixmaps as scatter points.
-
-  For custom shapes, you can provide a QPainterPath with the desired shape to the \ref
-  setCustomPath function or call the constructor that takes a painter path. The scatter shape will
-  automatically be set to \ref ssCustom.
-  
-  For pixmaps, you call \ref setPixmap with the desired QPixmap. Alternatively you can use the
-  constructor that takes a QPixmap. The scatter shape will automatically be set to \ref ssPixmap.
-  Note that \ref setSize does not influence the appearance of the pixmap.

-  Returns whether a pen has been defined for this scatter style.
-  
-  The pen is undefined if a constructor is called that does not carry \a pen as parameter. Those
-  are \ref QCPScatterStyle() and \ref QCPScatterStyle(ScatterShape shape, double size). If the pen
-  is undefined, the pen of the respective plottable will be used for drawing scatters.

-/*! \class QCPSelectionDecorator
-  \brief Controls how a plottable's data selection is drawn
-  
-  Each \ref QCPAbstractPlottable instance has one \ref QCPSelectionDecorator (accessible via \ref
-  QCPAbstractPlottable::selectionDecorator) and uses it when drawing selected segments of its data.
-  
-  The selection decorator controls both pen (\ref setPen) and brush (\ref setBrush), as well as the
-  scatter style (\ref setScatterStyle) if the plottable draws scatters. Since a \ref
-  QCPScatterStyle is itself composed of different properties such as color shape and size, the
-  decorator allows specifying exactly which of those properties shall be used for the selected data
-  point, via \ref setUsedScatterProperties.
-  
-  A \ref QCPSelectionDecorator subclass instance can be passed to a plottable via \ref
-  QCPAbstractPlottable::setSelectionDecorator, allowing greater customizability of the appearance
-  of selected segments.
-  
-  Use \ref copyFrom to easily transfer the settings of one decorator to another one. This is
-  especially useful since plottables take ownership of the passed selection decorator, and thus the
-  same decorator instance can not be passed to multiple plottables.
-  
-  Selection decorators can also themselves perform drawing operations by reimplementing \ref
-  drawDecoration, which is called by the plottable's draw method. The base class \ref
-  QCPSelectionDecorator does not make use of this however. For example, \ref
-  QCPSelectionDecoratorBracket draws brackets around selected data segments.

-/*! \class QCPAbstractPlottable
-  \brief The abstract base class for all data representing objects in a plot.
-
-  It defines a very basic interface like name, pen, brush, visibility etc. Since this class is
-  abstract, it can't be instantiated. Use one of the subclasses or create a subclass yourself to
-  create new ways of displaying data (see "Creating own plottables" below). Plottables that display
-  one-dimensional data (i.e. data points have a single key dimension and one or multiple values at
-  each key) are based off of the template subclass \ref QCPAbstractPlottable1D, see details
-  there.
-  
-  All further specifics are in the subclasses, for example:
-  \li A normal graph with possibly a line and/or scatter points \ref QCPGraph
-  (typically created with \ref QCustomPlot::addGraph)
-  \li A parametric curve: \ref QCPCurve
-  \li A bar chart: \ref QCPBars
-  \li A statistical box plot: \ref QCPStatisticalBox
-  \li A color encoded two-dimensional map: \ref QCPColorMap
-  \li An OHLC/Candlestick chart: \ref QCPFinancial
-  
-  \section plottables-subclassing Creating own plottables
-  
-  Subclassing directly from QCPAbstractPlottable is only recommended if you wish to display
-  two-dimensional data like \ref QCPColorMap, i.e. two logical key dimensions and one (or more)
-  data dimensions. If you want to display data with only one logical key dimension, you should
-  rather derive from \ref QCPAbstractPlottable1D.
-  
-  If subclassing QCPAbstractPlottable directly, these are the pure virtual functions you must
-  implement:
-  \li \ref selectTest
-  \li \ref draw
-  \li \ref drawLegendIcon
-  \li \ref getKeyRange
-  \li \ref getValueRange
-  
-  See the documentation of those functions for what they need to do.
-  
-  For drawing your plot, you can use the \ref coordsToPixels functions to translate a point in plot
-  coordinates to pixel coordinates. This function is quite convenient, because it takes the
-  orientation of the key and value axes into account for you (x and y are swapped when the key axis
-  is vertical and the value axis horizontal). If you are worried about performance (i.e. you need
-  to translate many points in a loop like QCPGraph), you can directly use \ref
-  QCPAxis::coordToPixel. However, you must then take care about the orientation of the axis
-  yourself.
-  
-  Here are some important members you inherit from QCPAbstractPlottable:
-  <table>
-  <tr>
-    <td>QCustomPlot *\b mParentPlot</td>
-    <td>A pointer to the parent QCustomPlot instance. The parent plot is inferred from the axes that are passed in the constructor.</td>
-  </tr><tr>
-    <td>QString \b mName</td>
-    <td>The name of the plottable.</td>
-  </tr><tr>
-    <td>QPen \b mPen</td>
-    <td>The generic pen of the plottable. You should use this pen for the most prominent data representing lines in the plottable
-        (e.g QCPGraph uses this pen for its graph lines and scatters)</td>
-  </tr><tr>
-    <td>QBrush \b mBrush</td>
-    <td>The generic brush of the plottable. You should use this brush for the most prominent fillable structures in the plottable
-        (e.g. QCPGraph uses this brush to control filling under the graph)</td>
-  </tr><tr>
-    <td>QPointer<\ref QCPAxis> \b mKeyAxis, \b mValueAxis</td>
-    <td>The key and value axes this plottable is attached to. Call their QCPAxis::coordToPixel functions to translate coordinates
-        to pixels in either the key or value dimension. Make sure to check whether the pointer is null before using it. If one of
-        the axes is null, don't draw the plottable.</td>
-  </tr><tr>
-    <td>\ref QCPSelectionDecorator \b mSelectionDecorator</td>
-    <td>The currently set selection decorator which specifies how selected data of the plottable shall be drawn and decorated.
-        When drawing your data, you must consult this decorator for the appropriate pen/brush before drawing unselected/selected data segments.
-        Finally, you should call its \ref QCPSelectionDecorator::drawDecoration method at the end of your \ref draw implementation.</td>
-  </tr><tr>
-    <td>\ref QCP::SelectionType \b mSelectable</td>
-    <td>In which composition, if at all, this plottable's data may be selected. Enforcing this setting on the data selection is done
-        by QCPAbstractPlottable automatically.</td>
-  </tr><tr>
-    <td>\ref QCPDataSelection \b mSelection</td>

-/*! \class QCPItemAnchor
-  \brief An anchor of an item to which positions can be attached to.
-  
-  An item (QCPAbstractItem) may have one or more anchors. Unlike QCPItemPosition, an anchor doesn't
-  control anything on its item, but provides a way to tie other items via their positions to the
-  anchor.
-
-  For example, a QCPItemRect is defined by its positions \a topLeft and \a bottomRight.
-  Additionally it has various anchors like \a top, \a topRight or \a bottomLeft etc. So you can
-  attach the \a start (which is a QCPItemPosition) of a QCPItemLine to one of the anchors by
-  calling QCPItemPosition::setParentAnchor on \a start, passing the wanted anchor of the
-  QCPItemRect. This way the start of the line will now always follow the respective anchor location
-  on the rect item.
-  
-  Note that QCPItemPosition derives from QCPItemAnchor, so every position can also serve as an
-  anchor to other positions.
-  
-  To learn how to provide anchors in your own item subclasses, see the subclassing section of the
-  QCPAbstractItem documentation.

-/*! \class QCPItemPosition
-  \brief Manages the position of an item.
-  
-  Every item has at least one public QCPItemPosition member pointer which provides ways to position the
-  item on the QCustomPlot surface. Some items have multiple positions, for example QCPItemRect has two:
-  \a topLeft and \a bottomRight.
-
-  QCPItemPosition has a type (\ref PositionType) that can be set with \ref setType. This type
-  defines how coordinates passed to \ref setCoords are to be interpreted, e.g. as absolute pixel
-  coordinates, as plot coordinates of certain axes, etc. For more advanced plots it is also
-  possible to assign different types per X/Y coordinate of the position (see \ref setTypeX, \ref
-  setTypeY). This way an item could be positioned at a fixed pixel distance from the top in the Y
-  direction, while following a plot coordinate in the X direction.
-
-  A QCPItemPosition may have a parent QCPItemAnchor, see \ref setParentAnchor. This way you can tie
-  multiple items together. If the QCPItemPosition has a parent, its coordinates (\ref setCoords)
-  are considered to be absolute pixels in the reference frame of the parent anchor, where (0, 0)
-  means directly ontop of the parent anchor. For example, You could attach the \a start position of
-  a QCPItemLine to the \a bottom anchor of a QCPItemText to make the starting point of the line
-  always be centered under the text label, no matter where the text is moved to. For more advanced
-  plots, it is possible to assign different parent anchors per X/Y coordinate of the position, see
-  \ref setParentAnchorX, \ref setParentAnchorY. This way an item could follow another item in the X
-  direction but stay at a fixed position in the Y direction. Or even follow item A in X, and item B
-  in Y.
-
-  Note that every QCPItemPosition inherits from QCPItemAnchor and thus can itself be used as parent
-  anchor for other positions.
-
-  To set the apparent pixel position on the QCustomPlot surface directly, use \ref setPixelPosition. This
-  works no matter what type this QCPItemPosition is or what parent-child situation it is in, as \ref
-  setPixelPosition transforms the coordinates appropriately, to make the position appear at the specified
-  pixel values.

-/*! \class QCPAbstractItem
-  \brief The abstract base class for all items in a plot.
-  
-  In QCustomPlot, items are supplemental graphical elements that are neither plottables
-  (QCPAbstractPlottable) nor axes (QCPAxis). While plottables are always tied to two axes and thus
-  plot coordinates, items can also be placed in absolute coordinates independent of any axes. Each
-  specific item has at least one QCPItemPosition member which controls the positioning. Some items
-  are defined by more than one coordinate and thus have two or more QCPItemPosition members (For
-  example, QCPItemRect has \a topLeft and \a bottomRight).
-  
-  This abstract base class defines a very basic interface like visibility and clipping. Since this
-  class is abstract, it can't be instantiated. Use one of the subclasses or create a subclass
-  yourself to create new items.
-  
-  The built-in items are:
-  <table>
-  <tr><td>QCPItemLine</td><td>A line defined by a start and an end point. May have different ending styles on each side (e.g. arrows).</td></tr>
-  <tr><td>QCPItemStraightLine</td><td>A straight line defined by a start and a direction point. Unlike QCPItemLine, the straight line is infinitely long and has no endings.</td></tr>
-  <tr><td>QCPItemCurve</td><td>A curve defined by start, end and two intermediate control points. May have different ending styles on each side (e.g. arrows).</td></tr>
-  <tr><td>QCPItemRect</td><td>A rectangle</td></tr>
-  <tr><td>QCPItemEllipse</td><td>An ellipse</td></tr>
-  <tr><td>QCPItemPixmap</td><td>An arbitrary pixmap</td></tr>
-  <tr><td>QCPItemText</td><td>A text label</td></tr>
-  <tr><td>QCPItemBracket</td><td>A bracket which may be used to reference/highlight certain parts in the plot.</td></tr>
-  <tr><td>QCPItemTracer</td><td>An item that can be attached to a QCPGraph and sticks to its data points, given a key coordinate.</td></tr>
-  </table>
-  
-  \section items-clipping Clipping
-
-  Items are by default clipped to the main axis rect (they are only visible inside the axis rect).
-  To make an item visible outside that axis rect, disable clipping via \ref setClipToAxisRect
-  "setClipToAxisRect(false)".
-
-  On the other hand if you want the item to be clipped to a different axis rect, specify it via
-  \ref setClipAxisRect. This clipAxisRect property of an item is only used for clipping behaviour, and
-  in principle is independent of the coordinate axes the item might be tied to via its position
-  members (\ref QCPItemPosition::setAxes). However, it is common that the axis rect for clipping
-  also contains the axes used for the item positions.
-  
-  \section items-using Using items
-  
-  First you instantiate the item you want to use and add it to the plot:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-1
-  by default, the positions of the item are bound to the x- and y-Axis of the plot. So we can just
-  set the plot coordinates where the line should start/end:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-2
-  If we don't want the line to be positioned in plot coordinates but a different coordinate system,
-  e.g. absolute pixel positions on the QCustomPlot surface, we need to change the position type like this:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-3
-  Then we can set the coordinates, this time in pixels:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-4
-  and make the line visible on the entire QCustomPlot, by disabling clipping to the axis rect:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpitemline-creation-5
-  
-  For more advanced plots, it is even possible to set different types and parent anchors per X/Y
-  coordinate of an item position, using for example \ref QCPItemPosition::setTypeX or \ref
-  QCPItemPosition::setParentAnchorX. For details, see the documentation of \ref QCPItemPosition.
-  
-  \section items-subclassing Creating own items
-  
-  To create an own item, you implement a subclass of QCPAbstractItem. These are the pure
-  virtual functions, you must implement:
-  \li \ref selectTest
-  \li \ref draw
-  
-  See the documentation of those functions for what they need to do.
-  
-  \subsection items-positioning Allowing the item to be positioned
-  
-  As mentioned, item positions are represented by QCPItemPosition members. Let's assume the new item shall
-  have only one point as its position (as opposed to two like a rect or multiple like a polygon). You then add
-  a public member of type QCPItemPosition like so:
-  
-  \code QCPItemPosition * const myPosition;\endcode
-  
-  the const makes sure the pointer itself can't be modified from the user of your new item (the QCPItemPosition
-  instance it points to, can be modified, of course).
-  The initialization of this pointer is made easy with the \ref createPosition function. Just assign
-  the return value of this function to each QCPItemPosition in the constructor of your item. \ref createPosition
-  takes a string which is the name of the position, typically this is identical to the variable name.
-  For example, the constructor of QCPItemExample could look like this:
-  
-  \code
-  QCPItemExample::QCPItemExample(QCustomPlot *parentPlot) :
-    QCPAbstractItem(parentPlot),
-    myPosition(createPosition("myPosition"))
-  {
-    // other constructor code
-  }
-  \endcode
-  
-  \subsection items-drawing The draw function
-  
-  To give your item a visual representation, reimplement the \ref draw function and use the passed
-  QCPPainter to draw the item. You can retrieve the item position in pixel coordinates from the
-  position member(s) via \ref QCPItemPosition::pixelPosition.
-
-  To optimize performance you should calculate a bounding rect first (don't forget to take the pen
-  width into account), check whether it intersects the \ref clipRect, and only draw the item at all
-  if this is the case.
-  
-  \subsection items-selection The selectTest function
-  
-  Your implementation of the \ref selectTest function may use the helpers \ref
-  QCPVector2D::distanceSquaredToLine and \ref rectDistance. With these, the implementation of the
-  selection test becomes significantly simpler for most items. See the documentation of \ref
-  selectTest for what the function parameters mean and what the function should return.
-  
-  \subsection anchors Providing anchors
-  
-  Providing anchors (QCPItemAnchor) starts off like adding a position. First you create a public
-  member, e.g.
-  
-  \code QCPItemAnchor * const bottom;\endcode
-
-  and create it in the constructor with the \ref createAnchor function, assigning it a name and an
-  anchor id (an integer enumerating all anchors on the item, you may create an own enum for this).
-  Since anchors can be placed anywhere, relative to the item's position(s), your item needs to
-  provide the position of every anchor with the reimplementation of the \ref anchorPixelPosition(int
-  anchorId) function.
-  
-  In essence the QCPItemAnchor is merely an intermediary that itself asks your item for the pixel
-  position when anything attached to the anchor needs to know the coordinates.

-  respective interaction is enabled, the user may drag axes ranges and zoom with the mouse wheel.
-  For details how to control which axes the user may drag/zoom and in what orientations, see \ref
-  QCPAxisRect::setRangeDrag, \ref QCPAxisRect::setRangeZoom, \ref QCPAxisRect::setRangeDragAxes,
-  \ref QCPAxisRect::setRangeZoomAxes.
-  
-  <b>Plottable data selection</b> is controlled by \ref QCP::iSelectPlottables. If \ref
-  QCP::iSelectPlottables is set, the user may select plottables (graphs, curves, bars,...) and
-  their data by clicking on them or in their vicinity (\ref setSelectionTolerance). Whether the
-  user can actually select a plottable and its data can further be restricted with the \ref
-  QCPAbstractPlottable::setSelectable method on the specific plottable. For details, see the
-  special page about the \ref dataselection "data selection mechanism". To retrieve a list of all
-  currently selected plottables, call \ref selectedPlottables. If you're only interested in
-  QCPGraphs, you may use the convenience function \ref selectedGraphs.
-  
-  <b>Item selection</b> is controlled by \ref QCP::iSelectItems. If \ref QCP::iSelectItems is set, the user
-  may select items (QCPItemLine, QCPItemText,...) by clicking on them or in their vicinity. To find
-  out whether a specific item is selected, call QCPAbstractItem::selected(). To retrieve a list of
-  all currently selected items, call \ref selectedItems.
-  
-  <b>Axis selection</b> is controlled with \ref QCP::iSelectAxes. If \ref QCP::iSelectAxes is set, the user
-  may select parts of the axes by clicking on them. What parts exactly (e.g. Axis base line, tick
-  labels, axis label) are selectable can be controlled via \ref QCPAxis::setSelectableParts for
-  each axis. To retrieve a list of all axes that currently contain selected parts, call \ref
-  selectedAxes. Which parts of an axis are selected, can be retrieved with QCPAxis::selectedParts().
-  
-  <b>Legend selection</b> is controlled with \ref QCP::iSelectLegend. If this is set, the user may
-  select the legend itself or individual items by clicking on them. What parts exactly are
-  selectable can be controlled via \ref QCPLegend::setSelectableParts. To find out whether the
-  legend or any of its child items are selected, check the value of QCPLegend::selectedParts. To
-  find out which child items are selected, call \ref QCPLegend::selectedItems.
-  
-  <b>All other selectable elements</b> The selection of all other selectable objects (e.g.
-  QCPTextElement, or your own layerable subclasses) is controlled with \ref QCP::iSelectOther. If set, the
-  user may select those objects by clicking on them. To find out which are currently selected, you
-  need to check their selected state explicitly.
-  
-  If the selection state has changed by user interaction, the \ref selectionChangedByUser signal is

-  their selection state has changed, i.e. not only by user interaction.

-  \warning This is still an experimental feature and its performance depends on the system that it

-  might cause context conflicts on some systems.
-  
-  This method allows to enable OpenGL plot rendering, for increased plotting performance of
-  graphically demanding plots (thick lines, translucent fills, etc.).
-
-  If \a enabled is set to true, QCustomPlot will try to initialize OpenGL and, if successful,
-  continue plotting with hardware acceleration. The parameter \a multisampling controls how many
-  samples will be used per pixel, it essentially controls the antialiasing quality. If \a
-  multisampling is set too high for the current graphics hardware, the maximum allowed value will
-  be used.
-
-  You can test whether switching to OpenGL rendering was successful by checking whether the
-  according getter \a QCustomPlot::openGl() returns true. If the OpenGL initialization fails,
-  rendering continues with the regular software rasterizer, and an according qDebug output is
-  generated.
-
-  If switching to OpenGL was successful, this method disables label caching (\ref setPlottingHint
-  "setPlottingHint(QCP::phCacheLabels, false)") and turns on QCustomPlot's antialiasing override
-  for all elements (\ref setAntialiasedElements "setAntialiasedElements(QCP::aeAll)"), leading to a
-  higher quality output. The antialiasing override allows for pixel-grid aligned drawing in the
-  OpenGL paint device. As stated before, in OpenGL rendering the actual antialiasing of the plot is
-  controlled with \a multisampling. If \a enabled is set to false, the antialiasing/label caching
-  settings are restored to what they were before OpenGL was enabled, if they weren't altered in the
-  meantime.
-
-  \note OpenGL support is only enabled if QCustomPlot is compiled with the macro \c QCUSTOMPLOT_USE_OPENGL
-  defined. This define must be set before including the QCustomPlot header both during compilation
-  of the QCustomPlot library as well as when compiling your application. It is best to just include
-  the line <tt>DEFINES += QCUSTOMPLOT_USE_OPENGL</tt> in the respective qmake project files.
-  \note If you are using a Qt version before 5.0, you must also add the module "opengl" to your \c
-  QT variable in the qmake project files. For Qt versions 5.0 and higher, QCustomPlot switches to a
-  newer OpenGL interface which is already in the "gui" module.

-  if your application calls \ref replot very quickly in succession (e.g. multiple independent
-  functions change some aspects of the plot and each wants to make sure the change gets replotted),
-  it is advisable to set \a refreshPriority to \ref QCustomPlot::rpQueuedReplot. This way, the
-  actual replotting is deferred to the next event loop iteration. Multiple successive calls of \ref
-  replot with this priority will only cause a single replot, avoiding redundant replots and
-  improving performance.
-
-  Under a few circumstances, QCustomPlot causes a replot by itself. Those are resize events of the
-  QCustomPlot widget and user interactions (object selection and range dragging/zooming).
-
-  Before the replot happens, the signal \ref beforeReplot is emitted. After the replot, \ref
-  afterReplot is emitted. It is safe to mutually connect the replot slot with any of those two
-  signals on two QCustomPlots to make them replot synchronously, it won't cause an infinite
-  recursion.
-
-  If a layer is in mode \ref QCPLayer::lmBuffered (\ref QCPLayer::setMode), it is also possible to
-  replot only that specific layer via \ref QCPLayer::replot. See the documentation there for
-  details.

-/*! \class QCPColorGradient
-  \brief Defines a color gradient for use with e.g. \ref QCPColorMap
-  
-  This class describes a color gradient which can be used to encode data with color. For example,
-  QCPColorMap and QCPColorScale have \ref QCPColorMap::setGradient "setGradient" methods which
-  take an instance of this class. Colors are set with \ref setColorStopAt(double position, const QColor &color)
-  with a \a position from 0 to 1. In between these defined color positions, the
-  color will be interpolated linearly either in RGB or HSV space, see \ref setColorInterpolation.
-
-  Alternatively, load one of the preset color gradients shown in the image below, with \ref
-  loadPreset, or by directly specifying the preset in the constructor.
-  
-  Apart from red, green and blue components, the gradient also interpolates the alpha values of the
-  configured color stops. This allows to display some portions of the data range as transparent in
-  the plot.
-  
-  \image html QCPColorGradient.png
-  
-  The \ref QCPColorGradient(GradientPreset preset) constructor allows directly converting a \ref
-  GradientPreset to a QCPColorGradient. This means that you can directly pass \ref GradientPreset
-  to all the \a setGradient methods, e.g.:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorgradient-setgradient
-  
-  The total number of levels used in the gradient can be set with \ref setLevelCount. Whether the
-  color gradient shall be applied periodically (wrapping around) to data values that lie outside
-  the data range specified on the plottable instance can be controlled with \ref setPeriodic.

-/*! \class QCPAxisRect
-  \brief Holds multiple axes and arranges them in a rectangular shape.
-  
-  This class represents an axis rect, a rectangular area that is bounded on all sides with an
-  arbitrary number of axes.
-  
-  Initially QCustomPlot has one axis rect, accessible via QCustomPlot::axisRect(). However, the
-  layout system allows to have multiple axis rects, e.g. arranged in a grid layout
-  (QCustomPlot::plotLayout).
-  
-  By default, QCPAxisRect comes with four axes, at bottom, top, left and right. They can be
-  accessed via \ref axis by providing the respective axis type (\ref QCPAxis::AxisType) and index.
-  If you need all axes in the axis rect, use \ref axes. The top and right axes are set to be
-  invisible initially (QCPAxis::setVisible). To add more axes to a side, use \ref addAxis or \ref
-  addAxes. To remove an axis, use \ref removeAxis.
-  
-  The axis rect layerable itself only draws a background pixmap or color, if specified (\ref
-  setBackground). It is placed on the "background" layer initially (see \ref QCPLayer for an
-  explanation of the QCustomPlot layer system). The axes that are held by the axis rect can be
-  placed on other layers, independently of the axis rect.
-  
-  Every axis rect has a child layout of type \ref QCPLayoutInset. It is accessible via \ref
-  insetLayout and can be used to have other layout elements (or even other layouts with multiple
-  elements) hovering inside the axis rect.
-  
-  If an axis rect is clicked and dragged, it processes this by moving certain axis ranges. The
-  behaviour can be controlled with \ref setRangeDrag and \ref setRangeDragAxes. If the mouse wheel
-  is scrolled while the cursor is on the axis rect, certain axes are scaled. This is controllable
-  via \ref setRangeZoom, \ref setRangeZoomAxes and \ref setRangeZoomFactor. These interactions are
-  only enabled if \ref QCustomPlot::setInteractions contains \ref QCP::iRangeDrag and \ref
-  QCP::iRangeZoom.

-  \brief A legend item representing a plottable with an icon and the plottable name.
-  
-  This is the standard legend item for plottables. It displays an icon of the plottable next to the

-  QCPAbstractPlottable::drawLegendIcon), and tries to give an intuitive symbol for the plottable.
-  For example, the QCPGraph draws a centered horizontal line and/or a single scatter point in the
-  middle.
-  
-  Legend items of this type are always associated with one plottable (retrievable via the
-  plottable() function and settable with the constructor). You may change the font of the plottable
-  name with \ref setFont. Icon padding and border pen is taken from the parent QCPLegend, see \ref
-  QCPLegend::setIconBorderPen and \ref QCPLegend::setIconTextPadding.
-
-  The function \ref QCPAbstractPlottable::addToLegend/\ref QCPAbstractPlottable::removeFromLegend

-  Since QCPLegend is based on QCPLayoutGrid, a legend item itself is just a subclass of

-/*! \class QCPLegend
-  \brief Manages a legend inside a QCustomPlot.
-
-  A legend is a small box somewhere in the plot which lists plottables with their name and icon.
-
-  A legend is populated with legend items by calling \ref QCPAbstractPlottable::addToLegend on the
-  plottable, for which a legend item shall be created. In the case of the main legend (\ref
-  QCustomPlot::legend), simply adding plottables to the plot while \ref
-  QCustomPlot::setAutoAddPlottableToLegend is set to true (the default) creates corresponding
-  legend items. The legend item associated with a certain plottable can be removed with \ref
-  QCPAbstractPlottable::removeFromLegend. However, QCPLegend also offers an interface to add and
-  manipulate legend items directly: \ref item, \ref itemWithPlottable, \ref itemCount, \ref
-  addItem, \ref removeItem, etc.
-
-  Since \ref QCPLegend derives from \ref QCPLayoutGrid, it can be placed in any position a \ref
-  QCPLayoutElement may be positioned. The legend items are themselves \ref QCPLayoutElement
-  "QCPLayoutElements" which are placed in the grid layout of the legend. \ref QCPLegend only adds
-  an interface specialized for handling child elements of type \ref QCPAbstractLegendItem, as
-  mentioned above. In principle, any other layout elements may also be added to a legend via the
-  normal \ref QCPLayoutGrid interface. See the special page about \link thelayoutsystem The Layout
-  System\endlink for examples on how to add other elements to the legend and move it outside the axis
-  rect.
-
-  Use the methods \ref setFillOrder and \ref setWrap inherited from \ref QCPLayoutGrid to control
-  in which order (column first or row first) the legend is filled up when calling \ref addItem, and
-  at which column or row wrapping occurs.
-
-  By default, every QCustomPlot has one legend (\ref QCustomPlot::legend) which is placed in the
-  inset layout of the main axis rect (\ref QCPAxisRect::insetLayout). To move the legend to another
-  position inside the axis rect, use the methods of the \ref QCPLayoutInset. To move the legend
-  outside of the axis rect, place it anywhere else with the \ref QCPLayout/\ref QCPLayoutElement
-  interface.

-/*! \class QCPColorScale
-  \brief A color scale for use with color coding data such as QCPColorMap
-  
-  This layout element can be placed on the plot to correlate a color gradient with data values. It
-  is usually used in combination with one or multiple \ref QCPColorMap "QCPColorMaps".
-
-  \image html QCPColorScale.png
-  
-  The color scale can be either horizontal or vertical, as shown in the image above. The
-  orientation and the side where the numbers appear is controlled with \ref setType.
-  
-  Use \ref QCPColorMap::setColorScale to connect a color map with a color scale. Once they are
-  connected, they share their gradient, data range and data scale type (\ref setGradient, \ref
-  setDataRange, \ref setDataScaleType). Multiple color maps may be associated with a single color
-  scale, to make them all synchronize these properties.
-  
-  To have finer control over the number display and axis behaviour, you can directly access the
-  \ref axis. See the documentation of QCPAxis for details about configuring axes. For example, if
-  you want to change the number of automatically generated ticks, call
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorscale-tickcount
-  
-  Placing a color scale next to the main axis rect works like with any other layout element:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorscale-creation
-  In this case we have placed it to the right of the default axis rect, so it wasn't necessary to
-  call \ref setType, since \ref QCPAxis::atRight is already the default. The text next to the color
-  scale can be set with \ref setLabel.
-  
-  For optimum appearance (like in the image above), it may be desirable to line up the axis rect and
-  the borders of the color scale. Use a \ref QCPMarginGroup to achieve this:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolorscale-margingroup
-  
-  Color scales are initialized with a non-zero minimum top and bottom margin (\ref
-  setMinimumMargins), because vertical color scales are most common and the minimum top/bottom
-  margin makes sure it keeps some distance to the top/bottom widget border. So if you change to a
-  horizontal color scale by setting \ref setType to \ref QCPAxis::atBottom or \ref QCPAxis::atTop, you
-  might want to also change the minimum margins accordingly, e.g. <tt>setMinimumMargins(QMargins(6, 0, 6, 0))</tt>.

-
-/*! \fn QCPAxis *QCPColorScale::axis() const
-  
-  Returns the internal \ref QCPAxis instance of this color scale. You can access it to alter the
-  appearance and behaviour of the axis. \ref QCPColorScale duplicates some properties in its
-  interface for convenience. Those are \ref setDataRange (\ref QCPAxis::setRange), \ref
-  setDataScaleType (\ref QCPAxis::setScaleType), and the method \ref setLabel (\ref
-  QCPAxis::setLabel). As they each are connected, it does not matter whether you use the method on
-  the QCPColorScale or on its QCPAxis.
-  
-  If the type of the color scale is changed with \ref setType, the axis returned by this method
-  will change, too, to either the left, right, bottom or top axis, depending on which type was set.

-/*! \class QCPGraph
-  \brief A plottable representing a graph in a plot.
-
-  \image html QCPGraph.png
-  
-  Usually you create new graphs by calling QCustomPlot::addGraph. The resulting instance can be
-  accessed via QCustomPlot::graph.
-
-  To plot data, assign it with the \ref setData or \ref addData functions. Alternatively, you can
-  also access and modify the data via the \ref data method, which returns a pointer to the internal
-  \ref QCPGraphDataContainer.
-  
-  Graphs are used to display single-valued data. Single-valued means that there should only be one
-  data point per unique key coordinate. In other words, the graph can't have \a loops. If you do
-  want to plot non-single-valued curves, rather use the QCPCurve plottable.
-  
-  Gaps in the graph line can be created by adding data points with NaN as value
-  (<tt>qQNaN()</tt> or <tt>std::numeric_limits<double>::quiet_NaN()</tt>) in between the two data points that shall be
-  separated.
-  
-  \section qcpgraph-appearance Changing the appearance
-  
-  The appearance of the graph is mainly determined by the line style, scatter style, brush and pen
-  of the graph (\ref setLineStyle, \ref setScatterStyle, \ref setBrush, \ref setPen).
-  
-  \subsection filling Filling under or between graphs
-  
-  QCPGraph knows two types of fills: Normal graph fills towards the zero-value-line parallel to
-  the key axis of the graph, and fills between two graphs, called channel fills. To enable a fill,
-  just set a brush with \ref setBrush which is neither Qt::NoBrush nor fully transparent.
-  
-  By default, a normal fill towards the zero-value-line will be drawn. To set up a channel fill
-  between this graph and another one, call \ref setChannelFillGraph with the other graph as
-  parameter.

-  sampling technique can drastically improve the replot performance for graphs with a larger number
-  of points (e.g. above 10,000), without notably changing the appearance of the graph.
-  
-  By default, adaptive sampling is enabled. Even if enabled, QCustomPlot decides whether adaptive
-  sampling shall actually be used on a per-graph basis. So leaving adaptive sampling enabled has no
-  disadvantage in almost all cases.
-  
-  \image html adaptive-sampling-line.png "A line plot of 500,000 points without and with adaptive sampling"
-  
-  As can be seen, line plots experience no visual degradation from adaptive sampling. Outliers are
-  reproduced reliably, as well as the overall shape of the data set. The replot time reduces
-  dramatically though. This allows QCustomPlot to display large amounts of data in realtime.
-  
-  \image html adaptive-sampling-scatter.png "A scatter plot of 100,000 points without and with adaptive sampling"
-  
-  Care must be taken when using high-density scatter plots in combination with adaptive sampling.
-  The adaptive sampling algorithm treats scatter plots more carefully than line plots which still
-  gives a significant reduction of replot times, but not quite as much as for line plots. This is
-  because scatter plots inherently need more data points to be preserved in order to still resemble
-  the original, non-adaptive-sampling plot. As shown above, the results still aren't quite
-  identical, as banding occurs for the outer data points. This is in fact intentional, such that
-  the boundaries of the data cloud stay visible to the viewer. How strong the banding appears,
-  depends on the point density, i.e. the number of points in the plot.
-  
-  For some situations with scatter plots it might thus be desirable to manually turn adaptive
-  sampling off. For example, when saving the plot to disk. This can be achieved by setting \a
-  enabled to false before issuing a command like \ref QCustomPlot::savePng, and setting \a enabled

-/*! \class QCPCurve
-  \brief A plottable representing a parametric curve in a plot.
-  
-  \image html QCPCurve.png
-  
-  Unlike QCPGraph, plottables of this type may have multiple points with the same key coordinate,
-  so their visual representation can have \a loops. This is realized by introducing a third
-  coordinate \a t, which defines the order of the points described by the other two coordinates \a
-  x and \a y.
-
-  To plot data, assign it with the \ref setData or \ref addData functions. Alternatively, you can
-  also access and modify the curve's data via the \ref data method, which returns a pointer to the
-  internal \ref QCPCurveDataContainer.
-  
-  Gaps in the curve can be created by adding data points with NaN as key and value
-  (<tt>qQNaN()</tt> or <tt>std::numeric_limits<double>::quiet_NaN()</tt>) in between the two data points that shall be
-  separated.
-  
-  \section qcpcurve-appearance Changing the appearance
-  
-  The appearance of the curve is determined by the pen and the brush (\ref setPen, \ref setBrush).
-  
-  \section qcpcurve-usage Usage
-  
-  Like all data representing objects in QCustomPlot, the QCPCurve is a plottable
-  (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
-  (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
-  
-  Usually, you first create an instance:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcurve-creation-1
-  which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot instance takes
-  ownership of the plottable, so do not delete it manually but use QCustomPlot::removePlottable() instead.
-  The newly created plottable can be modified, e.g.:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcurve-creation-2

-  regular \ref setData or \ref addData methods.

-  printed to the debug output (qDebug), the construction is not aborted, though.
-  
-  The created QCPCurve is automatically registered with the QCustomPlot instance inferred from \a

-  This function is part of the curve optimization algorithm of \ref getCurveLines.
-  
-  In situations where a single segment skips over multiple regions it might become necessary to add
-  extra points at the corners of region 5 (see \ref getRegion) such that the optimized segment
-  doesn't unintentionally cut through the visible area of the axis rect and create plot artifacts.
-  This method provides these points that must be added, assuming the original segment doesn't
-  start, end, or traverse region 5. (Corner points where region 5 is traversed are calculated by
-  \ref getTraverseCornerPoints.)
-  
-  For example, consider a segment which directly goes from region 4 to 2 but originally is far out
-  to the top left such that it doesn't cross region 5. Naively optimizing these points by
-  projecting them on the top and left borders of region 5 will create a segment that surely crosses
-  5, creating a visual artifact in the plot. This method prevents this by providing extra points at
-  the top left corner, making the optimized curve correctly pass from region 4 to 1 to 2 without
-  traversing 5.

-  This function is part of the curve optimization algorithm of \ref getCurveLines.
-  
-  This method assumes that the \ref getTraverse test has returned true, so the segment definitely
-  traverses the visible region 5 when going from \a prevRegion to \a currentRegion.
-  
-  In certain situations it is not sufficient to merely generate the entry and exit points of the
-  segment into/out of region 5, as \ref getTraverse provides. It may happen that a single segment, in
-  addition to traversing region 5, skips another region outside of region 5, which makes it
-  necessary to add an optimized corner point there (very similar to the job \ref
-  getOptimizedCornerPoints does for segments that are completely in outside regions and don't
-  traverse 5).
-  
-  As an example, consider a segment going from region 1 to region 6, traversing the lower left
-  corner of region 5. In this configuration, the segment additionally crosses the border between
-  region 1 and 2 before entering region 5. This makes it necessary to add an additional point in
-  the top left corner, before adding the optimized traverse points. So in this case, the output
-  parameter \a beforeTraverse will contain the top left corner point, and \a afterTraverse will be
-  empty.
-  
-  In some cases, such as when going from region 1 to 9, it may even be necessary to add additional
-  corner points before and after the traverse. Then both \a beforeTraverse and \a afterTraverse
-  return the respective corner points.

-  \brief Groups multiple QCPBars together so they appear side by side
-  
-  \image html QCPBarsGroup.png
-  
-  When showing multiple QCPBars in one plot which have bars at identical keys, it may be desirable
-  to have them appearing next to each other at each key. This is what adding the respective QCPBars
-  plottables to a QCPBarsGroup achieves. (An alternative approach is to stack them on top of each
-  other, see \ref QCPBars::moveAbove.)
-  
-  \section qcpbarsgroup-usage Usage
-  
-  To add a QCPBars plottable to the group, create a new group and then add the respective bars
-  intances:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpbarsgroup-creation
-  Alternatively to appending to the group like shown above, you can also set the group on the
-  QCPBars plottable via \ref QCPBars::setBarsGroup.
-  
-  The spacing between the bars can be configured via \ref setSpacingType and \ref setSpacing. The
-  bars in this group appear in the plot in the order they were appended. To insert a bars plottable
-  at a certain index position, or to reposition a bars plottable which is already in the group, use
-  \ref insert.
-  
-  To remove specific bars from the group, use either \ref remove or call \ref
-  QCPBars::setBarsGroup "QCPBars::setBarsGroup(0)" on the respective bars plottable.
-  
-  To clear the entire group, call \ref clear, or simply delete the group.

-  Bar charts are stackable. This means, two QCPBars plottables can be placed on top of each other
-  (see \ref QCPBars::moveAbove). So when two bars are at the same key position, they will appear
-  stacked.
-  
-  If you would like to group multiple QCPBars plottables together so they appear side by side as
-  shown below, use QCPBarsGroup.

-  \section qcpbars-usage Usage
-  
-  Like all data representing objects in QCustomPlot, the QCPBars is a plottable
-  (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
-  (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
-  
-  Usually, you first create an instance:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpbars-creation-1
-  which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot instance takes
-  ownership of the plottable, so do not delete it manually but use QCustomPlot::removePlottable() instead.
-  The newly created plottable can be modified, e.g.:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpbars-creation-2

-/*! \class QCPStatisticalBox
-  \brief A plottable representing a single statistical box in a plot.
-
-  \image html QCPStatisticalBox.png
-  
-  To plot data, assign it with the \ref setData or \ref addData functions. Alternatively, you can
-  also access and modify the data via the \ref data method, which returns a pointer to the internal
-  \ref QCPStatisticalBoxDataContainer.
-  
-  Additionally each data point can itself have a list of outliers, drawn as scatter points at the
-  key coordinate of the respective statistical box data point. They can either be set by using the
-  respective \ref addData(double,double,double,double,double,double,const QVector<double>&)
-  "addData" method or accessing the individual data points through \ref data, and setting the
-  <tt>QVector<double> outliers</tt> of the data points directly.
-  
-  \section qcpstatisticalbox-appearance Changing the appearance
-  
-  The appearance of each data point box, ranging from the lower to the upper quartile, is
-  controlled via \ref setPen and \ref setBrush. You may change the width of the boxes with \ref
-  setWidth in plot coordinates.
-
-  Each data point's visual representation also consists of two whiskers. Whiskers are the lines
-  which reach from the upper quartile to the maximum, and from the lower quartile to the minimum.
-  The appearance of the whiskers can be modified with: \ref setWhiskerPen, \ref setWhiskerBarPen,
-  \ref setWhiskerWidth. The whisker width is the width of the bar perpendicular to the whisker at
-  the top (for maximum) and bottom (for minimum). If the whisker pen is changed, make sure to set
-  the \c capStyle to \c Qt::FlatCap. Otherwise the backbone line might exceed the whisker bars by a
-  few pixels due to the pen cap being not perfectly flat.
-  
-  The median indicator line inside the box has its own pen, \ref setMedianPen.
-  
-  The outlier data points are drawn as normal scatter points. Their look can be controlled with
-  \ref setOutlierStyle
-  
-  \section qcpstatisticalbox-usage Usage
-  
-  Like all data representing objects in QCustomPlot, the QCPStatisticalBox is a plottable
-  (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
-  (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
-  
-  Usually, you first create an instance:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpstatisticalbox-creation-1
-  which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot instance takes
-  ownership of the plottable, so do not delete it manually but use QCustomPlot::removePlottable() instead.
-  The newly created plottable can be modified, e.g.:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpstatisticalbox-creation-2

-  convenient and faster than using the regular \ref setData or \ref addData methods.

-/*! \class QCPColorMapData
-  \brief Holds the two-dimensional data of a QCPColorMap plottable.
-  
-  This class is a data storage for \ref QCPColorMap. It holds a two-dimensional array, which \ref
-  QCPColorMap then displays as a 2D image in the plot, where the array values are represented by a
-  color, depending on the value.
-  
-  The size of the array can be controlled via \ref setSize (or \ref setKeySize, \ref setValueSize).
-  Which plot coordinates these cells correspond to can be configured with \ref setRange (or \ref
-  setKeyRange, \ref setValueRange).
-  
-  The data cells can be accessed in two ways: They can be directly addressed by an integer index
-  with \ref setCell. This is the fastest method. Alternatively, they can be addressed by their plot
-  coordinate with \ref setData. plot coordinate to cell index transformations and vice versa are
-  provided by the functions \ref coordToCell and \ref cellToCoord.
-  
-  A \ref QCPColorMapData also holds an on-demand two-dimensional array of alpha values which (if
-  allocated) has the same size as the data map. It can be accessed via \ref setAlpha, \ref
-  fillAlpha and \ref clearAlpha. The memory for the alpha map is only allocated if needed, i.e. on
-  the first call of \ref setAlpha. \ref clearAlpha restores full opacity and frees the alpha map.
-  
-  This class also buffers the minimum and maximum values that are in the data set, to provide
-  QCPColorMap::rescaleDataRange with the necessary information quickly. Setting a cell to a value
-  that is greater than the current maximum increases this maximum to the new value. However,
-  setting the cell that currently holds the maximum value to a smaller value doesn't decrease the
-  maximum again, because finding the true new maximum would require going through the entire data
-  array, which might be time consuming. The same holds for the data minimum. This functionality is
-  given by \ref recalculateDataBounds, such that you can decide when it is sensible to find the
-  true current minimum and maximum. The method QCPColorMap::rescaleDataRange offers a convenience
-  parameter \a recalculateDataBounds which may be set to true to automatically call \ref
-  recalculateDataBounds internally.

-/*! \class QCPColorMap
-  \brief A plottable representing a two-dimensional color map in a plot.
-
-  \image html QCPColorMap.png
-  
-  The data is stored in the class \ref QCPColorMapData, which can be accessed via the data()
-  method.
-  
-  A color map has three dimensions to represent a data point: The \a key dimension, the \a value
-  dimension and the \a data dimension. As with other plottables such as graphs, \a key and \a value
-  correspond to two orthogonal axes on the QCustomPlot surface that you specify in the QCPColorMap
-  constructor. The \a data dimension however is encoded as the color of the point at (\a key, \a
-  value).
-
-  Set the number of points (or \a cells) in the key/value dimension via \ref
-  QCPColorMapData::setSize. The plot coordinate range over which these points will be displayed is
-  specified via \ref QCPColorMapData::setRange. The first cell will be centered on the lower range
-  boundary and the last cell will be centered on the upper range boundary. The data can be set by
-  either accessing the cells directly with QCPColorMapData::setCell or by addressing the cells via
-  their plot coordinates with \ref QCPColorMapData::setData. If possible, you should prefer
-  setCell, since it doesn't need to do any coordinate transformation and thus performs a bit
-  better.
-  
-  The cell with index (0, 0) is at the bottom left, if the color map uses normal (i.e. not reversed)
-  key and value axes.
-  
-  To show the user which colors correspond to which \a data values, a \ref QCPColorScale is
-  typically placed to the right of the axis rect. See the documentation there for details on how to
-  add and use a color scale.
-  
-  \section qcpcolormap-appearance Changing the appearance
-  
-  The central part of the appearance is the color gradient, which can be specified via \ref
-  setGradient. See the documentation of \ref QCPColorGradient for details on configuring a color
-  gradient.
-  
-  The \a data range that is mapped to the colors of the gradient can be specified with \ref
-  setDataRange. To make the data range encompass the whole data set minimum to maximum, call \ref
-  rescaleDataRange.
-  
-  \section qcpcolormap-transparency Transparency
-  
-  Transparency in color maps can be achieved by two mechanisms. On one hand, you can specify alpha
-  values for color stops of the \ref QCPColorGradient, via the regular QColor interface. This will
-  cause the color map data which gets mapped to colors around those color stops to appear with the
-  accordingly interpolated transparency.
-  
-  On the other hand you can also directly apply an alpha value to each cell independent of its
-  data, by using the alpha map feature of \ref QCPColorMapData. The relevant methods are \ref
-  QCPColorMapData::setAlpha, QCPColorMapData::fillAlpha and \ref QCPColorMapData::clearAlpha().
-  
-  The two transparencies will be joined together in the plot and otherwise not interfere with each
-  other. They are mixed in a multiplicative matter, so an alpha of e.g. 50% (128/255) in both modes
-  simultaneously, will result in a total transparency of 25% (64/255).
-  
-  \section qcpcolormap-usage Usage
-  
-  Like all data representing objects in QCustomPlot, the QCPColorMap is a plottable
-  (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
-  (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
-  
-  Usually, you first create an instance:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolormap-creation-1
-  which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot instance takes
-  ownership of the plottable, so do not delete it manually but use QCustomPlot::removePlottable() instead.
-  The newly created plottable can be modified, e.g.:
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpcolormap-creation-2
-  
-  \note The QCPColorMap always displays the data at equal key/value intervals, even if the key or
-  value axis is set to a logarithmic scaling. If you want to use QCPColorMap with logarithmic axes,
-  you shouldn't use the \ref QCPColorMapData::setData method as it uses a linear transformation to
-  determine the cell index. Rather directly access the cell index with \ref
-  QCPColorMapData::setCell.

-/*! \class QCPFinancial
-  \brief A plottable representing a financial stock chart
-
-  \image html QCPFinancial.png
-
-  This plottable represents time series data binned to certain intervals, mainly used for stock
-  charts. The two common representations OHLC (Open-High-Low-Close) bars and Candlesticks can be
-  set via \ref setChartStyle.
-
-  The data is passed via \ref setData as a set of open/high/low/close values at certain keys
-  (typically times). This means the data must be already binned appropriately. If data is only
-  available as a series of values (e.g. \a price against \a time), you can use the static
-  convenience function \ref timeSeriesToOhlc to generate binned OHLC-data which can then be passed
-  to \ref setData.
-
-  The width of the OHLC bars/candlesticks can be controlled with \ref setWidth and \ref
-  setWidthType. A typical choice is to set the width type to \ref wtPlotCoords (the default) and
-  the width to (or slightly less than) one time bin interval width.
-
-  \section qcpfinancial-appearance Changing the appearance
-
-  Charts can be either single- or two-colored (\ref setTwoColored). If set to be single-colored,
-  lines are drawn with the plottable's pen (\ref setPen) and fills with the brush (\ref setBrush).
-
-  If set to two-colored, positive changes of the value during an interval (\a close >= \a open) are
-  represented with a different pen and brush than negative changes (\a close < \a open). These can
-  be configured with \ref setPenPositive, \ref setPenNegative, \ref setBrushPositive, and \ref
-  setBrushNegative. In two-colored mode, the normal plottable pen/brush is ignored. Upon selection
-  however, the normal selected pen/brush (provided by the \ref selectionDecorator) is used,
-  irrespective of whether the chart is single- or two-colored.
-
-  \section qcpfinancial-usage Usage
-
-  Like all data representing objects in QCustomPlot, the QCPFinancial is a plottable
-  (QCPAbstractPlottable). So the plottable-interface of QCustomPlot applies
-  (QCustomPlot::plottable, QCustomPlot::removePlottable, etc.)
-
-  Usually, you first create an instance:
-
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpfinancial-creation-1
-  which registers it with the QCustomPlot instance of the passed axes. Note that this QCustomPlot
-  instance takes ownership of the plottable, so do not delete it manually but use
-  QCustomPlot::removePlottable() instead. The newly created plottable can be modified, e.g.:
-
-  \snippet documentation/doc-code-snippets/mainwindow.cpp qcpfinancial-creation-2
-  Here we have used the static helper method \ref timeSeriesToOhlc, to turn a time-price data
-  series into a 24-hour binned open-high-low-close data series as QCPFinancial uses.

-  
-  Returns a pointer to the internal data storage of type \ref QCPFinancialDataContainer. You may

-  regular \ref setData or \ref addData methods, in certain situations.

-  printed to the debug output (qDebug), the construction is not aborted, though.

-  \brief A plottable that adds a set of error bars to other plottables.
-
-  \image html QCPErrorBars.png
-
-  The \ref QCPErrorBars plottable can be attached to other one-dimensional plottables (e.g. \ref
-  QCPGraph, \ref QCPCurve, \ref QCPBars, etc.) and equips them with error bars.
-
-  Use \ref setDataPlottable to define for which plottable the \ref QCPErrorBars shall display the
-  error bars. The orientation of the error bars can be controlled with \ref setErrorType.
-
-  By using \ref setData, you can supply the actual error data, either as symmetric error or
-  plus/minus asymmetric errors. \ref QCPErrorBars only stores the error data. The absolute
-  key/value position of each error bar will be adopted from the configured data plottable. The
-  error data of the \ref QCPErrorBars are associated one-to-one via their index to the data points
-  of the data plottable. You can directly access and manipulate the error bar data via \ref data.
-
-  Set either of the plus/minus errors to NaN (<tt>qQNaN()</tt> or
-  <tt>std::numeric_limits<double>::quiet_NaN()</tt>) to not show the respective error bar on the data point at
-  that index.
-
-  \section qcperrorbars-appearance Changing the appearance
-
-  The appearance of the error bars is defined by the pen (\ref setPen), and the width of the
-  whiskers (\ref setWhiskerWidth). Further, the error bar backbones may leave a gap around the data
-  point center to prevent that error bars are drawn too close to or even through scatter points.
-  This gap size can be controlled via \ref setSymbolGap.

-/*! \class QCPItemTracer
-  \brief Item that sticks to QCPGraph data points
-
-  \image html QCPItemTracer.png "Tracer example. Blue dotted circles are anchors, solid blue discs are positions."
-
-  The tracer can be connected with a QCPGraph via \ref setGraph. Then it will automatically adopt
-  the coordinate axes of the graph and update its \a position to be on the graph's data. This means
-  the key stays controllable via \ref setGraphKey, but the value will follow the graph data. If a
-  QCPGraph is connected, note that setting the coordinates of the tracer item directly via \a
-  position will have no effect because they will be overriden in the next redraw (this is when the
-  coordinate update happens).
-  
-  If the specified key in \ref setGraphKey is outside the key bounds of the graph, the tracer will
-  stay at the corresponding end of the graph.
-  
-  With \ref setInterpolating you may specify whether the tracer may only stay exactly on data
-  points or whether it interpolates data points linearly, if given a key that lies between two data
-  points of the graph.
-  
-  The tracer has different visual styles, see \ref setStyle. It is also possible to make the tracer
-  have no own visual appearance (set the style to \ref tsNone), and just connect other item
-  positions to the tracer \a position (used as an anchor) via \ref
-  QCPItemPosition::setParentAnchor.
-  
-  \note The tracer position is only automatically updated upon redraws. So when the data of the
-  graph changes and immediately afterwards (without a redraw) the position coordinates of the
-  tracer are retrieved, they will not reflect the updated data of the graph. In this case \ref
-  updatePosition must be called manually, prior to reading the tracer coordinates.

-/*! \class QCPDataContainer
-  \brief The generic data container for one-dimensional plottables
-
-  This class template provides a fast container for data storage of one-dimensional data. The data
-  type is specified as template parameter (called \a DataType in the following) and must provide
-  some methods as described in the \ref qcpdatacontainer-datatype "next section".
-
-  The data is stored in a sorted fashion, which allows very quick lookups by the sorted key as well
-  as retrieval of ranges (see \ref findBegin, \ref findEnd, \ref keyRange) using binary search. The
-  container uses a preallocation and a postallocation scheme, such that appending and prepending
-  data (with respect to the sort key) is very fast and minimizes reallocations. If data is added
-  which needs to be inserted between existing keys, the merge usually can be done quickly too,
-  using the fact that existing data is always sorted. The user can further improve performance by
-  specifying that added data is already itself sorted by key, if he can guarantee that this is the
-  case (see for example \ref add(const QVector<DataType> &data, bool alreadySorted)).
-
-  The data can be accessed with the provided const iterators (\ref constBegin, \ref constEnd). If
-  it is necessary to alter existing data in-place, the non-const iterators can be used (\ref begin,
-  \ref end). Changing data members that are not the sort key (for most data types called \a key) is
-  safe from the container's perspective.
-
-  Great care must be taken however if the sort key is modified through the non-const iterators. For
-  performance reasons, the iterators don't automatically cause a re-sorting upon their
-  manipulation. It is thus the responsibility of the user to leave the container in a sorted state
-  when finished with the data manipulation, before calling any other methods on the container. A
-  complete re-sort (e.g. after finishing all sort key manipulation) can be done by calling \ref
-  sort. Failing to do so can not be detected by the container efficiently and will cause both
-  rendering artifacts and potential data loss.
-
-  Implementing one-dimensional plottables that make use of a \ref QCPDataContainer<T> is usually
-  done by subclassing from \ref QCPAbstractPlottable1D "QCPAbstractPlottable1D<T>", which
-  introduces an according \a mDataContainer member and some convenience methods.
-
-  \section qcpdatacontainer-datatype Requirements for the DataType template parameter
-
-  The template parameter <tt>DataType</tt> is the type of the stored data points. It must be
-  trivially copyable and have the following public methods, preferably inline:
-
-  \li <tt>double sortKey() const</tt>\n Returns the member variable of this data point that is the
-  sort key, defining the ordering in the container. Often this variable is simply called \a key.
-
-  \li <tt>static DataType fromSortKey(double sortKey)</tt>\n Returns a new instance of the data
-  type initialized with its sort key set to \a sortKey.
-
-  \li <tt>static bool sortKeyIsMainKey()</tt>\n Returns true if the sort key is equal to the main
-  key (see method \c mainKey below). For most plottables this is the case. It is not the case for
-  example for \ref QCPCurve, which uses \a t as sort key and \a key as main key. This is the reason
-  why QCPCurve unlike QCPGraph can display parametric curves with loops.
-
-  \li <tt>double mainKey() const</tt>\n Returns the variable of this data point considered the main
-  key. This is commonly the variable that is used as the coordinate of this data point on the key
-  axis of the plottable. This method is used for example when determining the automatic axis
-  rescaling of key axes (\ref QCPAxis::rescale).
-
-  \li <tt>double mainValue() const</tt>\n Returns the variable of this data point considered the
-  main value. This is commonly the variable that is used as the coordinate of this data point on
-  the value axis of the plottable.
-
-  \li <tt>QCPRange valueRange() const</tt>\n Returns the range this data point spans in the value
-  axis coordinate. If the data is single-valued (e.g. QCPGraphData), this is simply a range with
-  both lower and upper set to the main data point value. However if the data points can represent
-  multiple values at once (e.g QCPFinancialData with its \a high, \a low, \a open and \a close
-  values at each \a key) this method should return the range those values span. This method is used
-  for example when determining the automatic axis rescaling of value axes (\ref
-  QCPAxis::rescale).

-/*! \class QCPPlottableInterface1D
-  \brief Defines an abstract interface for one-dimensional plottables
-
-  This class contains only pure virtual methods which define a common interface to the data
-  of one-dimensional plottables.
-
-  For example, it is implemented by the template class \ref QCPAbstractPlottable1D (the preferred
-  base class for one-dimensional plottables). So if you use that template class as base class of
-  your one-dimensional plottable, you won't have to care about implementing the 1d interface
-  yourself.
-
-  If your plottable doesn't derive from \ref QCPAbstractPlottable1D but still wants to provide a 1d
-  interface (e.g. like \ref QCPErrorBars does), you should inherit from both \ref
-  QCPAbstractPlottable and \ref QCPPlottableInterface1D and accordingly reimplement the pure
-  virtual methods of the 1d interface, matching your data container. Also, reimplement \ref
-  QCPAbstractPlottable::interface1D to return the \c this pointer.
-
-  If you have a \ref QCPAbstractPlottable pointer, you can check whether it implements this
-  interface by calling \ref QCPAbstractPlottable::interface1D and testing it for a non-zero return
-  value. If it indeed implements this interface, you may use it to access the plottable's data
-  without needing to know the exact type of the plottable or its data point type.

-  
-  If \a onlySelectable is true, an empty QCPDataSelection is returned if this plottable is not
-  selectable (i.e. if \ref QCPAbstractPlottable::setSelectable is \ref QCP::stNone).
-  
-  \note \a rect must be a normalized rect (positive or zero width and height). This is especially

-/*! \class QCPAbstractPlottable1D
-  \brief A template base class for plottables with one-dimensional data
-
-  This template class derives from \ref QCPAbstractPlottable and from the abstract interface \ref
-  QCPPlottableInterface1D. It serves as a base class for all one-dimensional data (i.e. data with
-  one key dimension), such as \ref QCPGraph and QCPCurve.
-
-  The template parameter \a DataType is the type of the data points of this plottable (e.g. \ref
-  QCPGraphData or \ref QCPCurveData). The main purpose of this base class is to provide the member
-  \a mDataContainer (a shared pointer to a \ref QCPDataContainer "QCPDataContainer<DataType>") and
-  implement the according virtual methods of the \ref QCPPlottableInterface1D, such that most
-  subclassed plottables don't need to worry about this anymore.
-
-  Further, it provides a convenience method for retrieving selected/unselected data segments via
-  \ref getDataSegments. This is useful when subclasses implement their \ref draw method and need to
-  draw selected segments with a different pen/brush than unselected segments (also see \ref
-  QCPSelectionDecorator).
-
-  This class implements basic functionality of \ref QCPAbstractPlottable::selectTest and \ref
-  QCPPlottableInterface1D::selectTestRect, assuming point-like data points, based on the 1D data
-  interface. In spite of that, most plottable subclasses will want to reimplement those methods
-  again, to provide a more accurate hit test based on their specific data visualization geometry.

+# Internal c++ interfaces
+
+The following interfaces are defined here:
+
+* [`Chain`](chain.h) — used by wallet to access blockchain and mempool state. Added in [#10973](https://github.com/bitcoin/bitcoin/pull/10973).
+
+* [`ChainClient`](chain.h) — used by node to start & stop `Chain` clients. Added in [#10973](https://github.com/bitcoin/bitcoin/pull/10973).
+
+* [`Node`](node.h) — used by GUI to start & stop bitcoin node. Added in [#10244](https://github.com/bitcoin/bitcoin/pull/10244).
+
+* [`Wallet`](wallet.h) — used by GUI to access wallets. Added in [#10244](https://github.com/bitcoin/bitcoin/pull/10244).
+
+* [`Handler`](handler.h) — returned by `handleEvent` methods on interfaces above and used to manage lifetimes of event handlers.
+
+* [`Init`](init.h) — used by multiprocess code to access interfaces above on startup. Added in [#10102](https://github.com/bitcoin/bitcoin/pull/10102).
+
+The interfaces above define boundaries between major components of bitcoin code (node, wallet, and gui), making it possible for them to run in different processes, and be tested, developed, and understood independently. These interfaces are not currently designed to be stable or to be used externally.

-# Internal c++ interfaces
-
-The following interfaces are defined here:
-
-* [`Chain`](chain.h) — used by wallet to access blockchain and mempool state. Added in [#10973](https://github.com/bitcoin/bitcoin/pull/10973).
-
-* [`ChainClient`](chain.h) — used by node to start & stop `Chain` clients. Added in [#10973](https://github.com/bitcoin/bitcoin/pull/10973).
-
-* [`Node`](node.h) — used by GUI to start & stop bitcoin node. Added in [#10244](https://github.com/bitcoin/bitcoin/pull/10244).
-
-* [`Wallet`](wallet.h) — used by GUI to access wallets. Added in [#10244](https://github.com/bitcoin/bitcoin/pull/10244).
-
-* [`Handler`](handler.h) — returned by `handleEvent` methods on interfaces above and used to manage lifetimes of event handlers.
-
-* [`Init`](init.h) — used by multiprocess code to access interfaces above on startup. Added in [#10102](https://github.com/bitcoin/bitcoin/pull/10102).
-
-The interfaces above define boundaries between major components of bitcoin code (node, wallet, and gui), making it possible for them to run in different processes, and be tested, developed, and understood independently. These interfaces are not currently designed to be stable or to be used externally.
