`matplotlib.pyplot` is a state-based interface to matplotlib. It provides
a MATLAB-like way of plotting.
pyplot is mainly intended for interactive plots and simple cases of
programmatic plot generation::
import numpy as np
import matplotlib.pyplot as plt
x = np.arange(0, 5, 0.1)
y = np.sin(x)
plt.plot(x, y)
The object-oriented API is recommended for more complex plots.

Create a new figure.
Parameters
----------
num : integer or string, optional, default: None
If not provided, a new figure will be created, and the figure number
will be incremented. The figure objects holds this number in a `number`
attribute.
If num is provided, and a figure with this id already exists, make
it active, and returns a reference to it. If this figure does not
exists, create it and returns it.
If num is a string, the window title will be set to this figure's
`num`.
figsize : (float, float), optional, default: None
width, height in inches. If not provided, defaults to
:rc:`figure.figsize` = ``[6.4, 4.8]``.
dpi : integer, optional, default: None
resolution of the figure. If not provided, defaults to
:rc:`figure.dpi` = ``100``.
facecolor : color spec
the background color. If not provided, defaults to
:rc:`figure.facecolor` = ``'w'``.
edgecolor : color spec
the border color. If not provided, defaults to
:rc:`figure.edgecolor` = ``'w'``.
frameon : bool, optional, default: True
If False, suppress drawing the figure frame.
FigureClass : subclass of `~matplotlib.figure.Figure`
Optionally use a custom `.Figure` instance.
clear : bool, optional, default: False
If True and the figure already exists, then it is cleared.
Returns
-------
figure : `~matplotlib.figure.Figure`
The `.Figure` instance returned will also be passed to
new_figure_manager in the backends, which allows to hook custom
`.Figure` classes into the pyplot interface. Additional kwargs will be
passed to the `.Figure` init function.
Notes
-----

"""
Add an axes to the current figure and make it the current axes.
Call signatures::
plt.axes()
plt.axes(rect, projection=None, polar=False, **kwargs)
plt.axes(ax)
Parameters
----------
arg : { None, 4-tuple, Axes }
The exact behavior of this function depends on the type:
- *None*: A new full window axes is added using
``subplot(111, **kwargs)``
- 4-tuple of floats *rect* = ``[left, bottom, width, height]``.
A new axes is added with dimensions *rect* in normalized
(0, 1) units using `~.Figure.add_axes` on the current figure.
- `~.axes.Axes`: This is equivalent to `.pyplot.sca`.
It sets the current axes to *arg*. Note: This implicitly
changes the current figure to the parent of *arg*.
.. note:: The use of an `.axes.Axes` as an argument is deprecated
and will be removed in v3.0. Please use `.pyplot.sca`
instead.
projection : {None, 'aitoff', 'hammer', 'lambert', 'mollweide', \
'polar', 'rectilinear', str}, optional
The projection type of the `~.axes.Axes`. *str* is the name of
a costum projection, see `~matplotlib.projections`. The default
None results in a 'rectilinear' projection.
polar : boolean, optional
If True, equivalent to projection='polar'.
sharex, sharey : `~.axes.Axes`, optional
Share the x or y `~matplotlib.axis` with sharex and/or sharey.
The axis will have the same limits, ticks, and scale as the axis
of the shared axes.
label : str
A label for the returned axes.
Other Parameters
----------------
**kwargs
This method also takes the keyword arguments for
the returned axes class. The keyword arguments for the
rectilinear axes class `~.axes.Axes` can be found in
the following table but there might also be other keyword
arguments if another projection is used, see the actual axes
class.
%(Axes)s
Returns
-------
axes : `~.axes.Axes` (or a subclass of `~.axes.Axes`)
The returned axes class depends on the projection used. It is
`~.axes.Axes` if rectilinear projection are used and
`.projections.polar.PolarAxes` if polar projection
are used.
Notes
-----
If the figure already has a axes with key (*args*,
*kwargs*) then it will simply make that axes current and
return it. This behavior is deprecated. Meanwhile, if you do
not want this behavior (i.e., you want to force the creation of a
new axes), you must use a unique set of args and kwargs. The axes
*label* attribute has been exposed for this purpose: if you want
two axes that are otherwise identical to be added to the figure,
make sure you give them unique labels.

Call signatures::

Parameters
----------
*args
Either a 3-digit integer or three separate integers
describing the position of the subplot. If the three
integers are *nrows*, *ncols*, and *index* in order, the
subplot will take the *index* position on a grid with *nrows*
rows and *ncols* columns. *index* starts at 1 in the upper left
corner and increases to the right.
*pos* is a three digit integer, where the first digit is the
number of rows, the second the number of columns, and the third
the index of the subplot. i.e. fig.add_subplot(235) is the same as
fig.add_subplot(2, 3, 5). Note that all integers must be less than
10 for this form to work.
projection : {None, 'aitoff', 'hammer', 'lambert', 'mollweide', \
'polar', 'rectilinear', str}, optional
The projection type of the subplot (`~.axes.Axes`). *str* is the name
of a costum projection, see `~matplotlib.projections`. The default
None results in a 'rectilinear' projection.
polar : boolean, optional
If True, equivalent to projection='polar'.
sharex, sharey : `~.axes.Axes`, optional
Share the x or y `~matplotlib.axis` with sharex and/or sharey. The
axis will have the same limits, ticks, and scale as the axis of the
shared axes.
label : str
A label for the returned axes.
Other Parameters
----------------
**kwargs
This method also takes the keyword arguments for
the returned axes base class. The keyword arguments for the
rectilinear base class `~.axes.Axes` can be found in
the following table but there might also be other keyword
arguments if another projection is used.
%(Axes)s
Returns
-------
axes : an `.axes.SubplotBase` subclass of `~.axes.Axes` (or a subclass \
of `~.axes.Axes`)
The axes of the subplot. The returned axes base class depends on
the projection used. It is `~.axes.Axes` if rectilinear projection
are used and `.projections.polar.PolarAxes` if polar projection
are used. The returned axes is then a subplot subclass of the
base class.
Notes
-----
Creating a subplot will delete any pre-existing subplot that overlaps
with it beyond sharing a boundary::
import matplotlib.pyplot as plt
# plot a line, implicitly creating a subplot(111)
plt.plot([1,2,3])
# now create a subplot which represents the top plot of a grid
# with 2 rows and 1 column. Since this subplot will overlap the
# first, the plot (and its axes) previously created, will be removed
plt.subplot(211)
If you do not want this behavior, use the `.Figure.add_subplot` method
or the `.pyplot.axes` function instead.
If the figure already has a subplot with key (*args*,
*kwargs*) then it will simply make that subplot current and
return it. This behavior is deprecated. Meanwhile, if you do
not want this behavior (i.e., you want to force the creation of a
new subplot), you must use a unique set of args and kwargs. The axes
*label* attribute has been exposed for this purpose: if you want
two subplots that are otherwise identical to be added to the figure,
make sure you give them unique labels.
In rare circumstances, `.add_subplot` may be called with a single
argument, a subplot axes instance already created in the
present figure but not in the figure's list of axes.

subplot_kw=None, gridspec_kw=None, **fig_kw):
"""
Create a figure and a set of subplots.
This utility wrapper makes it convenient to create common layouts of
subplots, including the enclosing figure object, in a single call.
Parameters
----------
nrows, ncols : int, optional, default: 1
Number of rows/columns of the subplot grid.
sharex, sharey : bool or {'none', 'all', 'row', 'col'}, default: False
Controls sharing of properties among x (`sharex`) or y (`sharey`)
axes:
- True or 'all': x- or y-axis will be shared among all
subplots.
- False or 'none': each subplot x- or y-axis will be
independent.
- 'row': each subplot row will share an x- or y-axis.
- 'col': each subplot column will share an x- or y-axis.
When subplots have a shared x-axis along a column, only the x tick
labels of the bottom subplot are created. Similarly, when subplots
have a shared y-axis along a row, only the y tick labels of the first
column subplot are created. To later turn other subplots' ticklabels
on, use `~matplotlib.axes.Axes.tick_params`.
squeeze : bool, optional, default: True
- If True, extra dimensions are squeezed out from the returned
array of `~matplotlib.axes.Axes`:
- if only one subplot is constructed (nrows=ncols=1), the
resulting single Axes object is returned as a scalar.
- for Nx1 or 1xM subplots, the returned object is a 1D numpy
object array of Axes objects.
- for NxM, subplots with N>1 and M>1 are returned as a 2D array.
- If False, no squeezing at all is done: the returned Axes object is
always a 2D array containing Axes instances, even if it ends up
being 1x1.
num : integer or string, optional, default: None
A `.pyplot.figure` keyword that sets the figure number or label.
subplot_kw : dict, optional
Dict with keywords passed to the
`~matplotlib.figure.Figure.add_subplot` call used to create each
subplot.
gridspec_kw : dict, optional
Dict with keywords passed to the `~matplotlib.gridspec.GridSpec`
constructor used to create the grid the subplots are placed on.
**fig_kw
All additional keyword arguments are passed to the
`.pyplot.figure` call.
Returns
-------
fig : `~.figure.Figure`
ax : `.axes.Axes` object or array of Axes objects.
*ax* can be either a single `~matplotlib.axes.Axes` object or an
array of Axes objects if more than one subplot was created. The
dimensions of the resulting array can be controlled with the squeeze
keyword, see above.
Examples
--------
::
# First create some toy data:
x = np.linspace(0, 2*np.pi, 400)
y = np.sin(x**2)
# Creates just a figure and only one subplot

"""
Matplotlib provides a number of colormaps, and others can be added using
:func:`~matplotlib.cm.register_cmap`. This function documents the built-in
colormaps, and will also return a list of all registered colormaps if
called.
You can set the colormap for an image, pcolor, scatter, etc,
using a keyword argument::
imshow(X, cmap=cm.hot)
or using the :func:`set_cmap` function::
imshow(X)
pyplot.set_cmap('hot')
pyplot.set_cmap('jet')
In interactive mode, :func:`set_cmap` will update the colormap post-hoc,
allowing you to see which one works best for your data.
All built-in colormaps can be reversed by appending ``_r``: For instance,
``gray_r`` is the reverse of ``gray``.
There are several common color schemes used in visualization:
Sequential schemes
for unipolar data that progresses from low to high
Diverging schemes
for bipolar data that emphasizes positive or negative deviations from a
central value
Cyclic schemes
for plotting values that wrap around at the endpoints, such as phase
angle, wind direction, or time of day
Qualitative schemes
for nominal data that has no inherent ordering, where color is used
only to distinguish categories
Matplotlib ships with 4 perceptually uniform color maps which are
the recommended color maps for sequential data:
========= ===================================================
Colormap Description
========= ===================================================
inferno perceptually uniform shades of black-red-yellow
magma perceptually uniform shades of black-red-white
plasma perceptually uniform shades of blue-red-yellow

The following colormaps are based on the `ColorBrewer
<http://colorbrewer2.org>`_ color specifications and designs developed by
Cynthia Brewer:

decreases towards differently-colored endpoints):

afmhot sequential black-orange-yellow-white blackbody
spectrum, commonly used in atomic force microscopy
brg blue-red-green
bwr diverging blue-white-red
coolwarm diverging blue-gray-red, meant to avoid issues with 3D
shading, color blindness, and ordering of colors [#]_
CMRmap "Default colormaps on color images often reproduce to
confusing grayscale images. The proposed colormap
maintains an aesthetically pleasing color image that
automatically reproduces to a monotonic grayscale with
discrete, quantifiable saturation levels." [#]_
cubehelix Unlike most other color schemes cubehelix was designed
by D.A. Green to be monotonically increasing in terms
of perceived brightness. Also, when printed on a black
and white postscript printer, the scheme results in a
greyscale with monotonically increasing brightness.
This color scheme is named cubehelix because the r,g,b
values produced can be visualised as a squashed helix
around the diagonal in the r,g,b color cube.

Plot the data in a file.
*cols* is a sequence of column identifiers to plot. An identifier
is either an int or a string. If it is an int, it indicates the
column number. If it is a string, it indicates the column header.
matplotlib will make column headers lower case, replace spaces with
underscores, and remove all illegal characters; so ``'Adj Close*'``
will have name ``'adj_close'``.
- If len(*cols*) == 1, only that column will be plotted on the *y* axis.
- If len(*cols*) > 1, the first element will be an identifier for
data for the *x* axis and the remaining elements will be the
column indexes for multiple subplots if *subplots* is *True*
(the default), or for lines in a single subplot if *subplots*
is *False*.
*plotfuncs*, if not *None*, is a dictionary mapping identifier to
an :class:`~matplotlib.axes.Axes` plotting function as a string.
Default is 'plot', other choices are 'semilogy', 'fill', 'bar',
etc. You must use the same type of identifier in the *cols*
vector as you use in the *plotfuncs* dictionary, e.g., integer
column numbers in both or column names in both. If *subplots*
is *False*, then including any function such as 'semilogy'
that changes the axis scaling will set the scaling for all
columns.
- *comments*: the character used to indicate the start of a comment
in the file, or *None* to switch off the removal of comments
- *skiprows*: is the number of rows from the top to skip
- *checkrows*: is the number of rows to check to validate the column
data type. When set to zero all rows are validated.
- *delimiter*: is the character(s) separating row items
- *names*: if not None, is a list of header names. In this case, no
header will be read from the file
If *newfig* is *True*, the plot always will be made in a new figure;
if *False*, it will be made in the current figure if one exists,
else in a new figure.
kwargs are passed on to plotting functions.
Example usage::
# plot the 2nd and 4th column against the 1st in two subplots
plotfile(fname, (0,1,3))
# plot using column names; specify an alternate plot type for volume
plotfile(fname, ('date', 'volume', 'adj_close'),
