2013-07-12 Added support for datetime axes to 2d plots. Axis values are passed
through Axes.convert_xunits/Axes.convert_yunits before being used by
contour/contourf, pcolormesh and pcolor.
2013-07-12 Allowed matplotlib.dates.date2num, matplotlib.dates.num2date,
and matplotlib.dates.datestr2num to accept n-d inputs. Also
factored in support for n-d arrays to matplotlib.dates.DateConverter
and matplotlib.units.Registry.
2013-06-26 Refactored the axes module: the axes module is now a folder,
containing the following submodule:
-, containing all the subplots helper methods
-, containing several private methods and a new
_AxesBase class. This _AxesBase class contains all the methods
that are not directly linked to plots of the "old" Axes
- contains the Axes class. This class now inherits from
_AxesBase: it contains all "plotting" methods and labelling
This refactoring should not affect the API. Only private methods
are not importable from the axes module anymore.
2013-05-18 Added support for arbitrary rasterization resolutions to the
SVG backend. Previously the resolution was hard coded to 72
dpi. Now the backend class takes a image_dpi argument for
its constructor, adjusts the image bounding box accordingly
and forwards a magnification factor to the image renderer.
The code and results now resemble those of the PDF backend.
- MW
2013-05-08 Changed behavior of hist when given stacked=True and normed=True.
Histograms are now stacked first, then the sum is normalized.
Previously, each histogram was normalized, then they were stacked.
2013-04-25 Changed all instances of:
from matplotlib import MatplotlibDeprecationWarning as mplDeprecation
from cbook import mplDeprecation
and removed the import into the matplotlib namespace in
Thomas Caswell
2013-04-15 Added 'axes.xmargin' and 'axes.ymargin' to rpParams to set default
margins on auto-scaleing. - TAC
2013-04-16 Added patheffect support for Line2D objects. -JJL
2013-03-19 Added support for passing `linestyle` kwarg to `step` so all `plot`
kwargs are passed to the underlying `plot` call. -TAC
2013-02-25 Added classes CubicTriInterpolator, UniformTriRefiner, TriAnalyzer
to matplotlib.tri module. - GBy
2013-01-23 Add '' to rcParams to remember and fill in the last
directory saved to for figure save dialogs - Martin Spacek
2013-01-13 Add eventplot method to axes and pyplot and EventCollection class
to collections.
2013-01-08 Added two extra titles to axes which are flush with the left and
right edges of the plot respectively.
Andrew Dawson
2013-01-07 Add framealpha keyword argument to legend - PO
2013-01-16 Till Stensitzki added a baseline feature to stackplot
2012-12-22 Added classes for interpolation within triangular grids
(LinearTriInterpolator) and to find the triangles in which points
lie (TrapezoidMapTriFinder) to matplotlib.tri module. - IMT
2012-12-05 Added MatplotlibDeprecationWarning class for signaling deprecation.
Matplotlib developers can use this class as follows:
from matplotlib import MatplotlibDeprecationWarning as mplDeprecation
In light of the fact that Python builtin DeprecationWarnings are
ignored by default as of Python 2.7, this class was put in to allow
for the signaling of deprecation, but via UserWarnings which are
not ignored by default. - PI
2012-11-27 Added the *mtext* parameter for supplying matplotlib.text.Text
instances to RendererBase.draw_tex and RendererBase.draw_text.
This allows backends to utilize additional text attributes, like
the alignment of text elements. - pwuertz
2012-11-26 deprecate matplotlib/, which was used only in and is
now replaced by the more suitable `import matplotlib as mpl`. - PI
2012-11-25 Make rc_context available via pyplot interface - PI
2012-11-16 plt.set_cmap no longer throws errors if there is not already
an active colorable artist, such as an image, and just sets
up the colormap to use from that point forward. - PI
2012-11-16 Added the funcction _get_rbga_face, which is identical to
_get_rbg_face except it return a (r,g,b,a) tuble, to line2D.
Modified Line2D.draw to use _get_rbga_face to get the markerface
color so that any alpha set by markerfacecolor will respected.
- Thomas Caswell
2012-11-13 Add a symmetric log normalization class to
Also added some tests for the normalization class.
Till Stensitzki
2012-11-12 Make axes.stem take at least one argument.
Uses a default range(n) when the first arg not provided.
Damon McDougall
2012-11-09 Make plt.subplot() without arguments act as subplot(111) - PI
2012-11-08 Replaced plt.figure and plt.subplot calls by the newer, more
convenient single call to plt.subplots() in the documentation
examples - PI
2012-10-05 Add support for saving animations as animated GIFs. - JVDP
2012-08-11 Fix path-closing bug in patches.Polygon, so that regardless
of whether the path is the initial one or was subsequently
set by set_xy(), get_xy() will return a closed path if and
only if get_closed() is True. Thanks to Jacob Vanderplas. - EF
2012-08-05 When a norm is passed to contourf, either or both of the
vmin, vmax attributes of that norm are now respected.
Formerly they were respected only if both were
specified. In addition, vmin and/or vmax can now
be passed to contourf directly as kwargs. - EF
2012-07-24 Contourf handles the extend kwarg by mapping the extended
ranges outside the normed 0-1 range so that they are
handled by colormap colors determined by the set_under
and set_over methods. Previously the extended ranges
were mapped to 0 or 1 so that the "under" and "over"
colormap colors were ignored. This change also increases
slightly the color contrast for a given set of contour
levels. - EF
2012-06-24 Make use of mathtext in tick labels configurable - DSD
2012-06-05 Images loaded through PIL are now ordered correctly - CG
2012-06-02 Add new Axes method and pyplot function, hist2d. - PO
2012-05-31 Remove support for 'cairo.<format>' style of backend specification.
Deprecate 'cairo.format' and 'savefig.extension' rcParams and
replace with 'savefig.format'. - Martin Spacek
2012-05-29 pcolormesh now obeys the passed in "edgecolor" kwarg.
To support this, the "shading" argument to pcolormesh now only
takes "flat" or "gouraud". To achieve the old "faceted" behavior,
pass "edgecolors='k'". - MGD
2012-05-22 Added radius kwarg to pie charts. - HH
2012-05-22 Collections now have a setting "offset_position" to select whether
the offsets are given in "screen" coordinates (default,
following the old behavior) or "data" coordinates. This is currently
used internally to improve the performance of hexbin.
As a result, the "draw_path_collection" backend methods have grown
a new argument "offset_position". - MGD
2012-05-04 Add a new argument to pie charts - startingangle - that
allows one to specify the angle offset for the first wedge
of the chart. - EP
2012-05-03 symlog scale now obeys the logarithmic base. Previously, it was
completely ignored and always treated as base e. - MGD
2012-05-03 Allow linscalex/y keyword to symlog scale that allows the size of
the linear portion relative to the logarithmic portion to be
adjusted. - MGD
2012-04-14 Added new plot style: stackplot. This new feature supports stacked
area plots. - Damon McDougall
2012-04-06 When path clipping changes a LINETO to a MOVETO, it also
changes any CLOSEPOLY command to a LINETO to the initial
point. This fixes a problem with pdf and svg where the
CLOSEPOLY would then draw a line to the latest MOVETO
position instead of the intended initial position. - JKS
2012-03-27 Add support to ImageGrid for placing colorbars only at
one edge of each column/row. - RMM
2012-03-07 Refactor movie writing into useful classes that make use
of pipes to write image data to ffmpeg or mencoder. Also
improve settings for these and the ability to pass custom
options. - RMM
2012-02-29 errorevery keyword added to errorbar to enable errorbar
subsampling. fixes issue #600.
2012-02-28 Added plot_trisurf to the mplot3d toolkit. This supports plotting
three dimensional surfaces on an irregular grid. - Damon McDougall
2012-01-23 The radius labels in polar plots no longer use a fixed
padding, but use a different alignment depending on the
quadrant they are in. This fixes numerical problems when
(rmax - rmin) gets too small. - MGD
2012-01-08 Add axes.streamplot to plot streamlines of a velocity field.
Adapted from Tom Flannaghan streamplot implementation. -TSY
2011-12-29 ps and pdf markers are now stroked only if the line width
is nonzero for consistency with agg, fixes issue #621. - JKS
2011-12-27 Work around an EINTR bug in some versions of subprocess. - JKS
2011-10-25 added support for \operatorname to mathtext,
including the ability to insert spaces, such as
$\operatorname{arg\,max}$ - PI
2011-08-18 Change api of Axes.get_tightbbox and add an optional
keyword parameter *call_axes_locator*. - JJL
2011-07-29 A new rcParam "axes.formatter.use_locale" was added, that,
when True, will use the current locale to format tick
labels. This means that, for example, in the fr_FR locale,
',' will be used as a decimal separator. - MGD
2011-07-15 The set of markers available in the plot() and scatter()
commands has been unified. In general, this gives more
options to both than were previously available, however,
there is one backward-incompatible change to the markers in
"d" used to mean "diamond", it now means "narrow
diamond". "D" can be used for a "diamond".
2011-07-13 Fix numerical problems in symlog scale, particularly when
linthresh <= 1.0. Symlog plots may look different if one
was depending on the old broken behavior - MGD
2011-07-10 Fixed argument handling error in tripcolor/triplot/tricontour,
issue #203. - IMT
2011-07-08 Many functions added to mplot3d.axes3d to bring Axes3D
objects more feature-parity with regular Axes objects.
Significant revisions to the documentation as well.
2011-07-07 Added compatibility with IPython strategy for picking
a version of Qt4 support, and an rcParam for making
the choice explicitly: backend.qt4. - EF
2011-07-07 Modified AutoMinorLocator to improve automatic choice of
the number of minor intervals per major interval, and
to allow one to specify this number via a kwarg. - EF
2011-06-28 3D versions of scatter, plot, plot_wireframe, plot_surface,
bar3d, and some other functions now support empty inputs. - BVR
2011-06-22 Add set_theta_offset, set_theta_direction and
set_theta_zero_location to polar axes to control the
location of 0 and directionality of theta. - MGD
2011-06-22 Add axes.labelweight parameter to set font weight to axis
labels - MGD.
2011-06-20 Add pause function to pyplot. - EF
2011-06-16 Added *bottom* keyword parameter for the stem command.
Also, implemented a legend handler for the stem plot.

2011-05-31 Made backend_qt4 compatible with PySide . - Gerald Storer
2011-04-17 Disable keyboard auto-repeat in qt4 backend by ignoring
key events resulting from auto-repeat. This makes
constrained zoom/pan work. - EF
2011-04-14 interpolation="nearest" always interpolate images. A new
mode "none" is introduced for no interpolation - JJL
2011-04-03 Fixed broken pick interface to AsteriskCollection objects
used by scatter. - EF
2011-04-01 The plot directive Sphinx extension now supports all of the
features in the Numpy fork of that extension. These
include doctest formatting, an 'include-source' option, and
a number of new configuration options. - MGD
2011-03-29 Wrapped ViewVCCachedServer definition in a factory function.
This class now inherits from urllib2.HTTPSHandler in order
to fetch data from github, but HTTPSHandler is not defined
if python was built without SSL support. - DSD
2011-03-10 Update pytz version to 2011c, thanks to Simon Cross. - JKS
2011-03-06 Add standalone test runner script. - JKS
2011-03-06 Set edgecolor to 'face' for scatter asterisk-type
symbols; this fixes a bug in which these symbols were
not responding to the c kwarg. The symbols have no
face area, so only the edgecolor is visible. - EF
2011-02-27 Support libpng version 1.5.x; suggestion by Michael
Albert. Changed installation specification to a
minimum of libpng version 1.2. - EF
2011-02-20 clabel accepts a callable as an fmt kwarg; modified
patch by Daniel Hyams. - EF
2011-02-18 scatter([], []) is now valid. Also fixed issues
with empty collections - BVR
2011-02-07 Quick workaround for dviread bug #3175113 - JKS
2011-02-05 Add cbook memory monitoring for Windows, using
tasklist. - EF
2011-02-05 Speed up Normalize and LogNorm by using in-place
operations and by using float32 for float32 inputs
and for ints of 2 bytes or shorter; based on
patch by Christoph Gohlke. - EF
2011-02-04 Changed imshow to use rgba as uint8 from start to
finish, instead of going through an intermediate
step as double precision; thanks to Christoph Gohlke. - EF
2011-01-13 Added zdir and offset arguments to contourf3d to
bring contourf3d in feature parity with contour3d. - BVR
2011-01-04 Tag 1.0.1 for release at r8896
2011-01-03 Added display of ticker offset to 3d plots. - BVR

pyplots.subplots when sharex/sharey is True. - JDH
2010-12-29 Implement axes_divider.HBox and VBox. -JJL
2010-11-22 Fixed error with Hammer projection. - BVR
2010-11-12 Fixed the placement and angle of axis labels in 3D plots. - BVR

by PIL for JPEG files. - JKS
2010-09-15 Remove unused _wxagg extension and numerix.h. - EF
2010-08-25 Add new framework for doing animations with examples.- RM
2010-08-21 Remove unused and inappropriate methods from Tick classes:
set_view_interval, get_minpos, and get_data_interval are
properly found in the Axis class and don't need to be
duplicated in XTick and YTick. - EF
2010-08-21 Change Axis.set_view_interval() so that when updating an
existing interval, it respects the orientation of that
interval, and can enlarge but not reduce the interval.
This fixes a bug in which Axis.set_ticks would
change the view limits of an inverted axis. Whether
set_ticks should be affecting the viewLim at all remains
an open question. - EF
2010-08-16 Handle NaN's correctly in path analysis routines. Fixes a
bug where the best location for a legend was not calculated
correctly when the line contains NaNs. - MGD
2010-08-14 Fix bug in patch alpha handling, and in bar color kwarg - EF
2010-08-12 Removed all traces of numerix module after 17 months of
deprecation warnings. - EF
2010-08-05 Added keyword arguments 'thetaunits' and 'runits' for polar
plots. Fixed PolarAxes so that when it set default
Formatters, it marked them as such. Fixed semilogx and
semilogy to no longer blindly reset the ticker information
on the non-log axis. Axes.arrow can now accept unitized
data. - JRE
2010-08-03 Add support for MPLSETUPCFG variable for custom setup.cfg
filename. Used by sage buildbot to build an mpl w/ no gui
support - JDH
2010-08-01 Create directory specified by MPLCONFIGDIR if it does
not exist. - ADS
2010-07-20 Return Qt4's default cursor when leaving the canvas - DSD
2010-07-06 Tagging for mpl 1.0 at r8502
2010-07-05 Added Ben Root's patch to put 3D plots in arbitrary axes,
allowing you to mix 3d and 2d in different axes/subplots or
to have multiple 3D plots in one figure. See
examples/mplot3d/ - JDH
2010-07-05 Preferred kwarg names in set_xlim are now 'left' and
'right'; in set_ylim, 'bottom' and 'top'; original
kwargs are still accepted without complaint. - EF
2010-07-05 TkAgg and FltkAgg backends are now consistent with other
interactive backends: when used in scripts from the
command line (not from ipython -pylab), show blocks,
and can be called more than once. - EF
2010-07-02 Modified CXX/WrapPython.h to fix "swab bug" on solaris so
mpl can compile on Solaris with CXX6 in the trunk. Closes
tracker bug 3022815 - JDH
2010-06-30 Added autoscale convenience method and corresponding
pyplot function for simplified control of autoscaling;
and changed axis, set_xlim, and set_ylim so that by
default, they turn off the autoscaling on the relevent
axis or axes. Therefore one can call set_xlim before
plotting a line, for example, and the limits will be
retained. - EF
2010-06-20 Added Axes.tick_params and corresponding pyplot function
to control tick and tick label appearance after an Axes
has been created. - EF
2010-06-09 Allow Axes.grid to control minor gridlines; allow
Axes.grid and Axis.grid to control major and minor
gridlines in the same method call. - EF
2010-06-06 Change the way we do split/dividend adjustments in to handle dividends and fix the zero division bug reported
in sf bug 2949906 and 2123566. Note that volume is not adjusted
because the Yahoo CSV does not distinguish between share
split and dividend adjustments making it near impossible to
get volume adjustement right (unless we want to guess based
on the size of the adjustment or scrape the html tables,
which we don't) - JDH
2010-06-06 Updated dateutil to 1.5 and pytz to 2010h.
2010-06-02 Add error_kw kwarg to - EF
2010-06-01 Fix pcolormesh() and QuadMesh to pass on kwargs as
appropriate. - RM
2010-05-18 Merge mpl_toolkits.gridspec into the main tree. - JJL
2010-05-04 Improve backend_qt4 so it displays figures with the
correct size - DSD
2010-04-20 Added generic support for connecting to a timer for events. This
adds TimerBase, TimerGTK, TimerQT, TimerWx, and TimerTk to
the backends and a new_timer() method to each backend's
canvas to allow ease of creating a new timer. - RM
2010-04-20 Added margins() Axes method and pyplot function. - EF
2010-04-18 update the axes_grid documentation. -JJL
2010-04-18 Control MaxNLocator parameters after instantiation,
and via Axes.locator_params method, with corresponding
pyplot function. -EF
2010-04-18 Control ScalarFormatter offsets directly and via the
Axes.ticklabel_format() method, and add that to pyplot. -EF
2010-04-16 Add a close_event to the backends. -RM
2010-04-06 modify axes_grid examples to use axes_grid1 and axisartist. -JJL
2010-04-06 rebase axes_grid using axes_grid1 and axisartist modules. -JJL
2010-04-06 axes_grid toolkit is splitted into two separate modules,
axes_grid1 and axisartist. -JJL
2010-04-05 Speed up import: import pytz only if and when it is
needed. It is not needed if the rc timezone is UTC. - EF
2010-04-03 Added color kwarg to Axes.hist(), based on work by
Jeff Klukas. - EF
2010-03-24 refactor colorbar code so that no cla() is necessary when
mappable is changed. -JJL
2010-03-22 fix incorrect rubber band during the zoom mode when mouse
leaves the axes. -JJL
2010-03-21 x/y key during the zoom mode only changes the x/y limits. -JJL
2010-03-20 Added function suggested by JJL. - EF
2010-03-20 Added conditional support for new Tooltip API in gtk backend. - EF
2010-03-20 Changed plt.fig_subplot() to plt.subplots() after discussion on
list, and changed its API to return axes as a numpy object array
(with control of dimensions via squeeze keyword). FP.

2010-02-25 add that demonstrates new functionality. -JJL
2010-02-25 refactor Annotation to support arbitrary Transform as xycoords
or textcoords. Also, if a tuple of two coordinates is provided,
they are interpreted as coordinates for each x and y position.
2010-02-24 Added pyplot.fig_subplot(), to create a figure and a group of
subplots in a single call. This offers an easier pattern than
manually making figures and calling add_subplot() multiple times. FP
2010-02-17 Added Gokhan's and Mattias' customizable keybindings patch
for the toolbar. You can now set the keymap.* properties
in the matplotlibrc file. Newbindings were added for
toggling log scaling on the x-axis. JDH
2010-02-16 Committed TJ's filled marker patch for
left|right|bottom|top|full filled markers. See
examples/pylab_examples/ JDH
2010-02-11 Added 'bootstrap' option to boxplot. This allows bootstrap
estimates of median confidence intervals. Based on an
initial patch by Paul Hobson. - ADS
2010-02-06 Added setup.cfg "basedirlist" option to override setting
in "basedir" dictionary; added "gnu0"
platform requested by Benjamin Drung. - EF
2010-02-06 Added 'xy' scaling option to EllipseCollection. - EF
2010-02-03 Made plot_directive use a custom PlotWarning category, so that
warnings can be turned into fatal errors easily if desired. - FP

placement. Thanks Adam Fraser. JDH
2010-01-25 Fixed a bug reported by Olle Engdegard, when using
histograms with stepfilled and log=True - MM
2010-01-16 Upgraded CXX to 6.1.1 - JDH
2009-01-16 Don't create minor ticks on top of existing major

2009-01-16 Ensure three minor ticks always drawn (SF# 2924245). Patch
by Neil Crighton. -ADS
2010-01-16 Applied patch by Ian Thomas to fix two contouring
problems: now contourf handles interior masked regions,
and the boundaries of line and filled contours coincide. - EF
2009-01-11 The color of legend patch follows the rc parameters
axes.facecolor and axes.edgecolor. -JJL
2009-01-11 adjustable of Axes can be "box-forced" which allow
sharing axes. -JJL
2009-01-11 Add add_click and pop_click methods in
BlockingContourLabeler. -JJL
2010-01-03 Added rcParams['axes.color_cycle'] - EF
2010-01-03 Added Pierre's qt4 formlayout editor and toolbar button - JDH
2009-12-31 Add support for using math text as marker symbols (Thanks to tcb)
2009-12-31 Commit a workaround for a regression in PyQt4-4.6.{0,1} - DSD
2009-12-22 Fix cmap data for gist_earth_r, etc. -JJL
2009-12-20 spines: put spines in data coordinates, add set_bounds()
call. -ADS
2009-12-18 Don't limit notch size in boxplot to q1-q3 range, as this
is effectively making the data look better than it is. - ADS
2009-12-18 mlab.prctile handles even-length data, such that the median
is the mean of the two middle values. - ADS
2009-12-15 Add raw-image (unsampled) support for the ps backend. - JJL
2009-12-14 Add patch_artist kwarg to boxplot, but keep old default.
Convert to use the new patch_artist. - ADS
2009-12-06 axes_grid: reimplemented AxisArtist with FloatingAxes support.
Added new examples. - JJL
2009-12-01 Applied Laurent Dufrechou's patch to improve blitting with
the qt4 backend - DSD
2009-11-13 The pdf backend now allows changing the contents of
a pdf file's information dictionary via PdfPages.infodict. - JKS
2009-11-12 should no longer cause EINTR on Python 2.6
(but will on the 2.5 version of subprocess). Also the
fc-list command in that file was fixed so now it should
actually find the list of fontconfig fonts. - JKS
2009-11-10 Single images, and all images in renderers with
option_image_nocomposite (i.e. agg, macosx and the svg
backend when rcParams['svg.image_noscale'] is True), are
now drawn respecting the zorder relative to other
artists. (Note that there may now be inconsistencies across
backends when more than one image is drawn at varying
zorders, but this change introduces correct behavior for
the backends in which it's easy to do so.)
2009-10-21 Make AutoDateLocator more configurable by adding options
to control the maximum and minimum number of ticks. Also
add control of the intervals to be used for ticking. This

the property tables in the rest docs broke of made
difficult to use some of the interactive doc helpers, e.g.,
setp and getp. Having all the rest markup in the ipython
shell also confused the docstrings. I added a new rc param
docstring.harcopy, to format the docstrings differently for
hardcopy and other use. Ther ArtistInspector could use a
little refactoring now since there is duplication of effort
between the rest out put and the non-rest output - JDH

In fact, under the hood, these all call the same core
to do computations. - RM
2008-11-11 Add 'pad_to' and 'sides' parameters to mlab.psd() to
allow controlling of zero padding and returning of
negative frequency components, respecitively. These are

object in place of a file path. - MGD
2007-11-13 Improved the default backend selection at build time:
SVG -> Agg -> TkAgg -> WXAgg -> GTK -> GTKAgg. The last usable
backend in this progression will be chosen in the default

be the default backend - DSD
2007-11-13 Improved creation of default config files at build time for
traited config package - DSD
2007-11-12 Exposed all the build options in setup.cfg. These options are

2007-11-12 Options to disable building backend extension modules moved
from to setup.cfg - DSD
2007-11-09 Applied Martin Teichmann's patch 1828813: a QPainter is used in

matplotlib raises an exception before the call to end - and it
does if you feed it with bad data - this method end() is never
called and Qt4 will start spitting error messages
2007-11-09 Moved pyparsing back into matplotlib namespace. Don't use
system pyparsing, API is too variable from one release

automatic level generation now works. - EF
The primary goal of this refactoring was to make it easier
to extend matplotlib to support new kinds of projections.
This is primarily an internal improvement, and the possible
user-visible changes it allows are yet to come.
The transformation framework was completely rewritten in
Python (with Numpy). This will make it easier to add news
kinds of transformations without writing C/C++ code.
Transforms are composed into a 'transform tree', made of
transforms whose value depends on other transforms (their
children). When the contents of children change, their
parents are automatically updated to reflect those changes.
To do this an "invalidation" method is used: when children
change, all of their ancestors are marked as "invalid".
When the value of a transform is accessed at a later time,
its value is recomputed only if it is invalid, otherwise a
cached value may be used. This prevents unnecessary
recomputations of transforms, and contributes to better
interactive performance.
The framework can be used for both affine and non-affine
transformations. However, for speed, we want use the
backend renderers to perform affine transformations
whenever possible. Therefore, it is possible to perform
just the affine or non-affine part of a transformation on a
set of data. The affine is always assumed to occur after
the non-affine. For any transform:
full transform == non-affine + affine
Much of the drawing has been refactored in terms of
compound paths. Therefore, many methods have been removed
from the backend interface and replaced with a a handful to
draw compound paths. This will make updating the backends
easier, since there is less to update. It also should make
the backends more consistent in terms of functionality.
User visible changes:
- POLAR PLOTS: Polar plots are now interactively zoomable,
and the r-axis labels can be interactively rotated.
Straight line segments are now interpolated to follow the
curve of the r-axis.
- Non-rectangular clipping works in more backends and with
more types of objects.
- Sharing an axis across figures is now done in exactly
the same way as sharing an axis between two axes in the
same figure:
fig1 = figure()
fig2 = figure()
ax1 = fig1.add_subplot(111)
ax2 = fig2.add_subplot(111, sharex=ax1, sharey=ax1)
- linestyles now include steps-pre, steps-post and
steps-mid. The old step still works and is equivalent to
- Multiple line styles may be provided to a collection.
See API_CHANGES for more low-level information about this
2007-10-24 Added ax kwarg to Figure.colorbar and pyplot.colorbar - EF
2007-10-19 Removed a gsave/grestore pair surrounding _draw_ps, which
was causing a loss graphics state info (see "EPS output
problem - scatter & edgecolors" on mpl-dev, 2007-10-29)
2007-10-15 Fixed a bug in patches.Ellipse that was broken for
aspect='auto'. Scale free ellipses now work properly for
equal and auto on Agg and PS, and they fall back on a
polygonal approximation for nonlinear transformations until
we convince oursleves that the spline approximation holds
for nonlinear transformations. Added
unit/ to compare spline with vertex
approx for both aspects. JDH
2007-10-05 remove generator expressions from texmanager and mpltraits.
generator expressions are not supported by python-2.3 - DSD
2007-10-01 Made matplotlib.use() raise an exception if called after
backends has been imported. - EF

2007-09-10 Made skiprows=1 the default on csv2rec - JDH
2007-09-09 Split out the plotting part of pylab and put it in; removed numerix from the remaining,
which imports everything from The intention
is that apart from cleanups, the result of importing
from pylab is nearly unchanged, but there is the
new alternative of importing from pyplot to get
the state-engine graphics without all the numeric
Numpified examples; deleted two that were obsolete;
modified some to use pyplot. - EF

2007-09-06 .bmp file format is now longer an alias for .raw
2007-09-07 Added clip path support to pdf backend. - JKS
2007-09-06 Fixed a bug in the embedding of Type 1 fonts in PDF.
Now it doesn't crash - JKS
2007-09-06 Refactored image saving code so that all GUI backends can
save most image types. See FILETYPES for a matrix of
backends and their supported file types.
Backend canvases should no longer write their own print_figure()
method -- instead they should write a print_xxx method for
each filetype they can output and add an entry to their
class-scoped filetypes dictionary. - MGD
2007-09-05 Fixed Qt version reporting in - DSD
2007-09-04 Embedding Type 1 fonts in PDF, and thus usetex support
via dviread, sort of works. To test, enable it by

font_manager module-level function findfont wrapper for
the fontManager.findfont method - EF
2007-08-11 Numpification and cleanup of and some examples - EF
2007-08-06 Removed mathtext2
2007-07-31 Refactoring of distutils scripts.
- Will not fail on the entire build if an optional Python
package (e.g., Tkinter) is installed but its development
headers are not (e.g., tk-devel). Instead, it will
continue to build all other extensions.
- Provide an overview at the top of the output to display
what dependencies and their versions were found, and (by
extension) what will be built.
- Use pkg-config, when available, to find freetype2, since
this was broken on Mac OS-X when using MacPorts in a non-
standard location.
2007-07-30 Reorganized configuration code to work with traited config
objects. The new config system is located in the
matplotlib.config package, but it is disabled by default.
To enable it, set NEWCONFIG=True in
The new configuration system will still use the old
matplotlibrc files by default. To switch to the experimental,
traited configuration, set USE_TRAITED_CONFIG=True in
2007-07-29 Changed default pcolor shading to flat; added aliases
to make collection kwargs agree with setter names, so
updating works; related minor cleanups.
Removed quiver_classic, scatter_classic, pcolor_classic. - EF
2007-07-26 Major rewrite of, using the TeX box layout model.
There is one (known) backward incompatible change. The
font commands (\cal, \rm, \it, \tt) now behave as TeX does:
they are in effect until the next font change command or
the end of the grouping. Therefore uses of $\cal{R}$
should be changed to ${\cal R}$. Alternatively, you may
use the new LaTeX-style font commands (\mathcal, \mathrm,
\mathit, \mathtt) which do affect the following group,
e.g., $\mathcal{R}$.
Other new features include:
- Math may be interspersed with non-math text. Any text
with an even number of $'s (non-escaped) will be sent to
the mathtext parser for layout.
- Sub/superscripts are less likely to accidentally overlap.
- Support for sub/superscripts in either order, e.g., $x^i_j$
and $x_j^i$ are equivalent.
- Double sub/superscripts (e.g., $x_i_j$) are considered
ambiguous and raise an exception. Use braces to disambiguate.
- $\frac{x}{y}$ can be used for displaying fractions.
- $\sqrt[3]{x}$ can be used to display the radical symbol
with a root number and body.
- $\left(\frac{x}{y}\right)$ may be used to create
parentheses and other delimiters that automatically
resize to the height of their contents.
- Spacing around operators etc. is now generally more like
- Added support (and fonts) for boldface (\bf) and
sans-serif (\sf) symbols.
- Log-like function name shortcuts are supported. For
example, $\sin(x)$ may be used instead of ${\rm sin}(x)$
- Limited use of kerning for the easy case (same font)
Behind the scenes, the module used for doing
the math parsing was updated to the latest stable version
(1.4.6). A lot of duplicate code was refactored out of the
Font classes.

Figure.clf() in which _axobservers was not getting
cleared. Modernization and cleanups. - EF
2007-03-26 Refactored some of the units support -- units now live in
the respective x and y Axis instances. See also
API_CHANGES for some alterations to the conversion

2007-03-22 Some more niceties for xcorr -- a maxlags option, normed
now works for xcorr as well as axorr, usevlines is
supported, and a zero correlation hline is added. See
examples/ Thanks Sameer for the patch. -
2007-03-21 Axes.vlines and Axes.hlines now create and returns a
LineCollection, not a list of lines. This is much faster.
The kwarg signature has changed, so consult the docs.
Modified Axes.errorbar which uses vlines and hlines. See
API_CHANGES; the return signature for these three functions

Fixes sf bug #1669506.
2007-03-02 Add rc parameter pdf.inheritcolor, which disables all
color-setting operations in the pdf backend. The idea is
that you include the resulting file in another program and
set the colors (both stroke and fill color) there, so you
can use the same pdf file for e.g., a paper and a
presentation and have them in the surrounding color. You
will probably not want to draw figure and axis frames in
that case, since they would be filled in the same color. - JKS
2007-02-26 Prevent building with broken Mac OS X wxPython. - ADS
2007-02-23 Require setuptools for Python 2.3 - ADS
2007-02-22 WXAgg accelerator updates - KM
WXAgg's C++ accelerator has been fixed to use the correct wxBitmap
The backend has been updated to use new wxPython functionality to
provide fast blit() animation without the C++ accelerator. This
requires wxPython 2.8 or later. Previous versions of wxPython can
use the C++ acclerator or the old pure Python routines. no longer builds the C++ accelerator when wxPython >= 2.8
is present.
The blit() method is now faster regardless of which agg/wxPython
conversion routines are used.
2007-02-21 Applied the PDF backend patch by Nicolas Grilly.
This impacts several files and directories in matplotlib:
- Created the directory lib/matplotlib/mpl-data/fonts/pdfcorefonts,
holding AFM files for the 14 PDF core fonts. These fonts are
embedded in every PDF viewing application.
- Added the directory pdfcorefonts to package_data.
- lib/matplotlib/ Added the default parameter
'pdf.use14corefonts'. When True, the PDF backend uses
only the 14 PDF core fonts.
- lib/matplotlib/ Added some keywords found in
recent AFM files. Added a little workaround to handle
Euro symbol.
- lib/matplotlib/ Added support for the 14
PDF core fonts. These fonts have a dedicated cache (file
pdfcorefont.cache), not the same as for other AFM files
(file .afmfont.cache). Also cleaned comments to conform
- lib/matplotlib/backends/
Added support for 14 PDF core fonts.
Fixed some issues with incorrect character widths and
encodings (works only for the most common encoding,
WinAnsiEncoding, defined by the official PDF Reference).
Removed parameter 'dpi' because it causes alignment issues.

develop mode works. Re-organized the mpl-data layout so
that this source structure is maintained in the

sub-directories are maintained in site-packages.) Suggest
removing site-packages/matplotlib/mpl-data and
~/.matplotlib/ttffont.cache before installing - ADS

collections. Added support for user customizable pick hit
testing and attribute tagging of the PickEvent - Details

2007-01-16 Begun work on a new pick API using the mpl event handling
frameowrk. Artists will define their own pick method with
a configurable epsilon tolerance and return pick attrs.
All artists that meet the tolerance threshold will fire a
PickEvent with artist dependent attrs; e.g., a Line2D can set
the indices attribute that shows the indices into the line
that are within epsilon of the pick point. See
examples/ The implementation of pick
for the remaining Artists remains to be done, but the core
infrastructure at the level of event handling is in place
with a proof-of-concept implementation for Line2D - JDH

correlation of x vs y or the autocorrelation of x. pylab
wrappers also provided. See examples/ - JDH
2007-01-10 Added "Subplot.label_outer" method. It will set the
visibility of the ticklabels so that yticklabels are only
visible in the first column and xticklabels are only
visible in the last row - JDH
2007-01-02 Added additional kwarg documentation - JDH
2006-12-28 Improved error message for nonpositive input to log
transform; added log kwarg to bar, barh, and hist,
and modified bar method to behave sensibly by default
when the ordinate has a log scale. (This only works
if the log scale is set before or by the call to bar,
hence the utility of the log kwarg.) - EF

in ScalarFormatter - EF
2006-12-16 Enhanced boxplot to handle more flexible inputs - EF
2006-12-13 Replaced calls to where() in with much faster
clip() and putmask() calls; removed inappropriate

very rarely); all in response to profiling by
David Cournapeau. Also fixed bugs in my 2-D
array support from 12-09. - EF
2006-12-09 Replaced spy and spy2 with the new spy that combines
marker and image capabilities - EF

columns are plotted as in Matlab - EF
2006-12-09 Added linewidth kwarg to bar and barh; fixed arg
checking bugs - EF
2006-12-07 Made pcolormesh argument handling match pcolor;
fixed kwarg handling problem noted by Pierre GM - EF
2006-12-06 Made pcolor support vector X and/or Y instead of
requiring 2-D arrays - EF
2006-12-05 Made the default Artist._transform None (rather than
invoking identity_transform for each artist only to have it
overridden later). Use artist.get_transform() rather than
artist._transform, even in derived classes, so that the
default transform will be created lazily as needed - JDH
2006-12-03 Added LogNorm to as illustrated by
examples/, based on suggestion by
Jim McDonald. Colorbar modified to handle LogNorm.
Norms have additional "inverse" method. - EF
2006-12-02 Changed class names in to match convention:
normalize -> Normalize, no_norm -> NoNorm. Old names
are still available.
Changed rc defaults to match those in
matplotlibrc - EF
2006-11-22 Fixed bug in set_*lim that I had introduced on 11-15 - EF
2006-11-22 Added examples/, which shows how to clip line

examples/ JDH
2006-10-12 Committed Manuel Metz's StarPolygon code and
examples/ - JDH
2006-10-11 commented out all default values in matplotlibrc.template
Default values should generally be taken from defaultParam in - the file matplotlib should only contain those values
that the user wants to explicitly change from the default.
(see thread "marker color handling" on matplotlib-devel)
2006-10-10 Changed default comment character for load to '#' - JDH
2006-10-10 deactivated rcfile-configurability of markerfacecolor
and markeredgecolor. Both are now hardcoded to the special value
'auto' to follow the line color. Configurability at run-time
(using function arguments) remains functional. - NN
2006-10-07 introduced dummy argument magnification=1.0 to
FigImage.make_image to satisfy unit test
The argument is not yet handled correctly, which should only
show up when using non-standard DPI settings in PS backend,
introduced by patch #1562394. - NN
2006-10-06 add backend-agnostic example: - NN
2006-09-29 fix line-breaking for SVG-inline images (purely cosmetic) - NN
2006-09-29 reworked set_linestyle and set_marker
markeredgecolor and markerfacecolor now default to
a special value "auto" that keeps the color in sync with
the line color
further, the intelligence of axes.plot is cleaned up,
improved and simplified. Complete compatibility cannot be
guaranteed, but the new behavior should be much more predictable
(see patch #1104615 for details) - NN
2006-09-29 changed implementation of clip-path in SVG to work around a
limitation in inkscape - NN

2006-06-26 Fixed a usetex bug. On windows, usetex will prcess
postscript output in the current directory rather than
in a temp directory. This is due to the use of spaces
and tildes in windows paths, which cause problems with
latex. The subprocess module is no longer used. - DSD
2006-06-22 Various changes to bar(), barh(), and hist().
Added 'edgecolor' keyword arg to bar() and barh().
The x and y args in barh() have been renamed to width
and bottom respectively, and their order has been swapped
to maintain a (position, value) order ala matlab. left,
height, width and bottom args can now all be scalars or
sequences. barh() now defaults to edge alignment instead
of center alignment. Added a keyword arg 'align' to bar(),
barh() and hist() that controls between edge or center bar
alignment. Fixed ignoring the rcParams['patch.facecolor']
for bar color in bar() and barh(). Fixed ignoring the
rcParams['lines.color'] for error bar color in bar()
and barh(). Fixed a bug where patches would be cleared
when error bars were plotted if rcParams['axes.hold']
was False. - MAS

gist_rainbow, gist_gray, gist_yarg, gist_heat, gist_ncar) - JW
2006-06-16 Added a pointer to parent in figure canvas so you can
access the container with fig.canvas.manager. Useful if
you want to set the window title, e.g., in gtk
fig.canvas.manager.window.set_title, though a GUI neutral
method would be preferable JDH
2006-06-16 Fixed to handle indexed colors (i.e.,
norm = no_norm()) by centering each colored region
on its index. - EF
2006-06-15 Added scalex and scaley to Axes.autoscale_view to support
selective autoscaling just the x or y axis, and supported
these command in plot so you can say plot(something,
scaley=False) and just the x axis will be autoscaled.
Modified axvline and axhline to support this, so for
example axvline will no longer autoscale the y axis. JDH

2006-04-05 Use python's subprocess module for usetex calls to
external programs. subprocess catches when they exit
abnormally so an error can be raised. - DSD

many possibilities in matplotlib._get_data_path() - CM
2005-12-11 Support for setuptools/pkg_resources to build and use
matplotlib as an egg. Still allows matplotlib to exist
using a traditional distutils install. - ADS
2005-12-03 Modified setup to build matplotlibrc based on compile time
findings. It will set numerix in the order of scipy,
numarray, Numeric depending on which are founds, and
backend as in preference order GTKAgg, WXAgg, TkAgg, GTK,
Agg, PS
2005-12-03 Modified scipy patch to support Numeric, scipy and numarray
Some work remains to be done because some of the scipy

2005-11-27 Multiple changes in,,,,,; new, examples/
1) Separated the color table data from out into
a new file,, to make it easier to find the actual
code in and to add new colormaps. Also added
some line breaks to the color data dictionaries. Everything
from is imported by, so the split should be
2) Enabled automatic generation of a colormap from
a list of colors in contour; see modified
3) Support for imshow of a masked array, with the
ability to specify colors (or no color at all) for
masked regions, and for regions that are above or
below the normally mapped region. See
4) In support of the above, added two new classes,
ListedColormap, and no_norm, to, and modified
the Colormap class to include common functionality. Added
a clip kwarg to the normalize class. Reworked color
handling in, especially in the ContourLabeller

2005-07-07 Added Eric's MA set_xdata Line2D fix - JDH
2005-07-06 Made HOME/.matplotlib the new config dir where the
matplotlibrc file, the ttf.cache, and the tex.cache live.
The new default filenames in .matplotlib have no leading
dot and are not hidden. e.g., the new names are matplotlibrc
tex.cache ttffont.cache. This is how ipython does it so it
must be right. If old files are found, a warning is issued
and they are moved to the new location. Also fixed
texmanager to put all files, including temp files in
~/.matplotlib/tex.cache, which allows you to usetex in
non-writable dirs.
2005-07-05 Fixed bug #1231611 in subplots adjust layout. The problem
was that the text cacheing mechanism was not using the
transformation affine in the key. - JDH

2005-06-19 Added 10.4 support for CocoaAgg. - CM
2005-06-18 Move Figure.get_width_height() to FigureCanvasBase and return
int instead of float. - SC
2005-06-18 Applied Ted Drain's QtAgg patch: 1) Changed the toolbar to
be a horizontal bar of push buttons instead of a QToolbar
and updated the layout algorithms in the main window
accordingly. This eliminates the ability to drag and drop
the toolbar and detach it from the window. 2) Updated the
resize algorithm in the main window to show the correct
size for the plot widget as requested. This works almost
correctly right now. It looks to me like the final size of
the widget is off by the border of the main window but I
haven't figured out a way to get that information yet. We
could just add a small margin to the new size but that
seems a little hacky. 3) Changed the x/y location label to
be in the toolbar like the Tk backend instead of as a
status line at the bottom of the widget. 4) Changed the
toolbar pixmaps to use the ppm files instead of the png
files. I noticed that the Tk backend buttons looked much
nicer and it uses the ppm files so I switched them.
2005-06-17 Modified the gtk backend to not queue mouse motion events.
This allows for live updates when dragging a slider. - CM
2005-06-17 Added starter CocoaAgg backend. Only works on OS 10.3 for
now and requires PyObjC. (10.4 is high priority) - CM
2005-06-17 Upgraded pyparsing and applied Paul McGuire's suggestions
for speeding things up. This more than doubles the speed
of mathtext in my simple tests. JDH
2005-06-16 Applied David Cooke's subplot make_key patch
2005-06-15 0.82 released
2005-06-15 Added subplot config tool to GTK* backends -- note you must
now import the NavigationToolbar2 from your backend of
choice rather than from backend_gtk because it needs to
know about the backend specific canvas -- see
examples/ Ditto for wx backend -- see
2005-06-15 updated to use pycairo 0.5.0 - SC
2005-06-14 Wrote some GUI neutral widgets (Button, Slider,
RadioButtons, CheckButtons) in matplotlib.widgets. See
examples/widgets/*.py - JDH
2005-06-14 Exposed subplot parameters as rc vars and as the fig
SubplotParams instance subplotpars. See
figure.SubplotParams, figure.Figure.subplots_adjust and the
pylab method subplots_adjust and
examples/ . Also added a GUI neutral
widget for adjusting subplots, see
examples/ - JDH
2005-06-13 Exposed cap and join style for lines with new rc params and
line properties
lines.dash_joinstyle : miter # miter|round|bevel

2005-06-05 Fixed a TeX/LaTeX font discrepency in backend_ps. - DSD
2005-06-05 Added a ps.distill option in rc settings. If True, postscript
output will be distilled using ghostscript, which should trim
the file size and allow it to load more quickly. Hopefully this
will address the issue of large ps files due to font
definitions. Tested with gnu-ghostscript-8.16. - DSD
2005-06-03 Improved support for tex handling of text in backend_ps. - DSD
2005-06-03 Added rc options to render text with tex or latex, and to select

2005-05-31 Added vertical TeX support for agg - JDH
2005-05-31 Applied Eric's cntr patch - JDH
2005-05-27 Finally found the pesky agg bug (which Maxim was kind
enough to fix within hours) that was causing a segfault in
the win32 cached marker drawing. Now windows users can get
the enormouse performance benefits of caced markers w/o
those occasional pesy screenshots. - JDH
2005-05-27 Got win32 build system working again, using a more recent
version of gtk and pygtk in the win32 build, gtk 2.6 from (you
will also need libpng12.dll to use these). I haven't
tested whether this binary build of mpl for win32 will work
with older gtk runtimes, so you may need to upgrade.
2005-05-27 Fixed bug where 2nd wxapp could be started if using wxagg
backend. - ADS
2005-05-26 Added Daishi text with dash patch -- see examples/
2005-05-26 Moved backend_latex functionality into backend_ps. If
text.usetex=True, the PostScript backend will use LaTeX to
generate the .ps or .eps file. Ghostscript is required for
eps output. - DSD
2005-05-24 Fixed alignment and color issues in latex backend. - DSD
2005-05-21 Fixed raster problem for small rasters with dvipng -- looks
like it was a premultipled alpha problem - JDH

edgewidth and color. Also added autolegend patch to
inspect line segments.
2005-05-18 Added Orsay and JPL qt fixes - JDH
2005-05-17 Added a psfrag latex backend -- some alignment issues need
to be worked out. Run with -dLaTeX and a *.tex file and
*.eps file are generated. latex and dvips the generated
latex file to get ps output. Note xdvi *does* not work,
you must generate ps.- JDH
2005-05-13 Added Florent Rougon's Axis set_label1
2005-05-17 pcolor optimization, fixed bug in previous pcolor patch - JSWHIT
2005-05-16 Added support for masked arrays in pcolor - JSWHIT
2005-05-12 Started work on TeX text for antigrain using pngdvi -- see
examples/ and the new module
matplotlib.texmanager. Rotated text not supported and
rendering small glyps is not working right yet. BUt large
fontsizes and/or high dpi saved figs work great.
2005-05-10 New image resize options interpolation options. New values
for the interp kwarg are
'nearest', 'bilinear', 'bicubic', 'spline16', 'spline36',
'hanning', 'hamming', 'hermite', 'kaiser', 'quadric',
'catrom', 'gaussian', 'bessel', 'mitchell', 'sinc',
'lanczos', 'blackman'
See help(imshow) for details, particularly the
interpolation, filternorm and filterrad kwargs
2005-05-10 Applied Eric's contour mem leak fixes - JDH
2005-05-10 Extended python agg wrapper and started implementing
backend_agg2, an agg renderer based on the python wrapper.

released 2) turn on cursor changes 3) clean up a typo
and commented-out print statement. - JDH
2005-04-14 Applied Eric Firing's masked data lines patch and contour
patch. Support for masked arrays has been added to the
plot command and to the Line2D object. Only the valid
points are plotted. A "valid_only" kwarg was added to the
get_xdata() and get_ydata() methods of Line2D; by default
it is False, so that the original data arrays are
returned. Setting it to True returns the plottable points.
- see examples/ - JDH
2005-04-13 Applied Tim Leslie's arrow key event handling patch - JDH
0.80 released
2005-04-11 Applied a variant of rick's xlim/ylim/axis patch. These
functions now take kwargs to let you selectively alter only
the min or max if desired. e.g., xlim(xmin=2) or
axis(ymax=3). They always return the new lim. - JDH
2005-04-11 Incorporated Werner's wx patch -- wx backend should be
compatible with wxpython2.4 and recent versions of 2.5.
Some early versions of wxpython 2.5 will not work because
there was a temporary change in the dc API that was rolled
back to make it 2.4 compliant

2005-03-15 changed to use double buffering, this fixes
the problem reported Joachim Berdal Haga - "Parts of plot lagging
from previous frame in animation". Tested with and it makes
no noticable difference to performance (23.7 before, 23.6 after)
- SC
2005-03-14 add src/_backend_gdk.c extension to provide a substitute function
for pixbuf.get_pixels_array(). Currently pixbuf.get_pixels_array()
only works with Numeric, and then only works if pygtk has been
compiled with Numeric support. The change provides a function
pixbuf_get_pixels_array() which works with Numeric and numarray and
is always available. It means that backend_gtk should be able to
display images and mathtext in all circumstances. - SC
2005-03-11 Upgraded CXX to 5.3.1
2005-03-10 remove GraphicsContextPS.set_linestyle()
and GraphicsContextSVG.set_linestyle() since they do no more than

2005-03-09 only use enumerate() (the python version) if the builtin
version is not available.
Add new function 'izip' which is set to itertools.izip if available
and the python equivalent if not available. - SC
2005-03-07 remove PIXELS_PER_INCH from points_to_pixels(), but
still use it to adjust font sizes. This allows the GTK version of to more closely match GTKAgg, previously the markers
were being drawn too large. - SC
2005-03-01 Added Eric's contourf routines
2005-03-01 Added start of proper agg SWIG wrapper. I would like to
expose agg functionality directly a the user level and this
module will serve that purpose eventually, and will
hopefully take over most of the functionality of the
current _image and _backend_agg modules. - JDH

arrays - JDH
2005-02-25 Add experimental feature to to enable/disable
double buffering (DBL_BUFFER=True/False) - SC
2005-02-24 change ColorConverter.to_rgb() so it always returns rgb
(and not rgba), allow cnames keys to be cached, change the exception
raised from RuntimeError to ValueError (like hex2color())
hex2color() use a regular expression to check the color string is
valid - SC
2005-02-23 Added rc param ps.useafm so backend ps can use native afm
fonts or truetype. afme breaks mathtext but causes much
smaller font sizes and may result in images that display
better in some contexts (e.g., pdfs incorporated into latex
docs viewed in acrobat reader). I would like to extend
this approach to allow the user to use truetype only for
mathtext, which should be easy.
2005-02-23 Used sequence protocol rather than tuple in agg collection
drawing routines for greater flexibility - JDH
2005-02-22 0.72.1 released

Added colormaps as default for contour - JDH
2005-01-19 Restored builtin names which were overridden (min, max,
abs, round, and sum) in pylab. This is a potentially
significant change for those who were relying on an array
version of those functions that previously overrode builtin
function names. - ADS
2005-01-18 Added accents to mathtext: \hat, \breve, \grave, \bar,
\acute, \tilde, \vec, \dot, \ddot. All of them have the
same syntax, e.g., to make an overbar you do \bar{o} or to
make an o umlaut you do \ddot{o}. The shortcuts are also
provided, e.g., \"o \'e \`e \~n \.x \^y - JDH
2005-01-18 Plugged image resize memory leaks - JDH

2004-12-28 Fixed coords notification in wx toolbar - JDH
2004-12-28 Moved connection and disconnection event handling to the
FigureCanvasBase. Backends now only need to connect one
time for each of the button press, button release and key
press/release functions. The base class deals with
callbacks and multiple connections. This fixes flakiness
on some backends (tk, wx) in the presence of multiple
connections and/or disconnect - JDH

2004-12-21 Refactored axes and subplot management - removed
add_subplot and add_axes from the FigureManager. classic
toolbar updates are done via an observer pattern on the
figure using add_axobserver. Figure now maintains the axes
stack (for gca) and supports axes deletion. Ported changes
to GTK, Tk, Wx, and FLTK. Please test! Added delaxes - JDH
2004-12-21 Lots of image optimizations - 4x performance boost over
0.65 JDH
2004-12-20 Fixed a figimage bug where the axes is shown and modified
tkagg to move the destroy binding into the show method.

2004-12-13 rgb2hex(), hex2color() made simpler (and faster), also
rgb2hex() - added round() instead of integer truncation
hex2color() - changed 256.0 divisor to 255.0, so now
'#ffffff' becomes (1.0,1.0,1.0) not (0.996,0.996,0.996) - SC
2004-12-11 Added ion and ioff to pylab interface - JDH
2004-12-11 delete FigureCanvasTemplate.realize() - most
backends don't use it and its no longer needed, delete show() and
draw_if_interactive() - they are not needed for image backends write direct to file instead of StringIO
- SC
2004-12-10 Added zorder to artists to control drawing order of lines,
patches and text in axes. See examples/ - JDH
2004-12-10 Fixed colorbar bug with scatter - JDH
2004-12-10 Added Nadia Dencheva <> contour code - JDH

state. - JDH
2004-11-25 Added Printf to mplutils for printf style format string
formatting in C++ (should help write better exceptions)
