of markers - JDH
2008-12-15 Removed mpl_data symlink in docs. On platforms that do not
support symlinks, these become copies, and the font files
are large, so the distro becomes unneccessarily bloaded.
Keeping the mpl_examples dir because relative links are
harder for the plot directive and the *.py files are not so
large. - JDH

2008-12-08 Some of the changes Michael made to improve the output of
the property tables in the rest docs broke of made
difficult to use some of the interactive doc helpers, eg
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
2008-12-08 Updated spectral methods (psd, csd, etc.) to scale one-sided
densities by a factor of 2 and, optionally, scale all densities

subclasses of the Style classes. A few more box and arrow
styles are added. -JJL

and use them to determine whether either or both
coordinates are used when updating dataLim. This is
used to fix autoscaling problems that had been triggered
by axhline, axhspan, axvline, axvspan. - EF
2008-11-11 Update the psd(), csd(), cohere(), and specgram() methods
of Axes and the csd() cohere(), and specgram() functions
in mlab to be in sync with the changes to psd().
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
added in a way that does not change the API. - RM
2008-11-10 Fix handling of c kwarg by scatter; generalize
is_string_like to accept numpy and numpy.ma string
array scalars. - RM and EF

just a regular file. savefig() can be passed a file-like
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

'stixsans':
The STIX fonts, using sans-serif glyphs by default
'custom':
A generic Unicode font, in which case the mathtext font
must be specified using mathtext.bf, mathtext.it,
mathtext.sf etc.
Added a new example, stix_fonts_demo.py to show how to access
different fonts and unusual symbols.

2007-11-09 Applied Martin Teichmann's patch 1828813: a QPainter is used in
paintEvent, which has to be destroyed using the method end(). If
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

2007-10-29 TRANSFORMS REFACTORING
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
step-pre.
- Multiple line styles may be provided to a collection.
See API_CHANGES for more low-level information about this
refactoring.
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)
- DSD
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/ellipse_compare.py 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
2007-09-30 Modified update* methods of Bbox and Interval so they
work with reversed axes. Prior to this, trying to
set the ticks on a reversed axis failed with an
uninformative error message. - EF
2007-09-30 Applied patches to axes3d to fix index error problem - EF
2007-09-24 Applied Eike Welk's patch reported on mpl-dev on 2007-09-22
Fixes a bug with multiple plot windows in the qt backend,
ported the changes to backend_qt4 as well - DSD
2007-09-21 Changed cbook.reversed to yield the same result as the
python reversed builtin - DSD
2007-09-13 The usetex support in the pdf backend is more usable now,
so I am enabling it. - JKS
2007-09-12 Fixed a Axes.bar unit bug - JDH
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
pyplot.py; removed numerix from the remaining pylab.py,
which imports everything from pyplot.py. 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
functions.
Numpified examples; deleted two that were obsolete;
modified some to use pyplot. - EF
2007-09-08 Eliminated gd and paint backends - 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 Preview.app. - 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 setupext.py - DSD
2007-09-04 Embedding Type 1 fonts in PDF, and thus usetex support
via dviread, sort of works. To test, enable it by
renaming _draw_tex to draw_tex. - JKS
2007-09-03 Added ability of errorbar show limits via caret or
arrowhead ends on the bars; patch by Manual Metz. - EF
2007-09-03 Created type1font.py, added features to AFM and FT2Font
(see API_CHANGES), started work on embedding Type 1 fonts
in pdf files. - JKS
2007-09-02 Continued work on dviread.py. - JKS
2007-08-16 Added a set_extent method to AxesImage, allow data extent
to be modified after initial call to imshow - DSD
2007-08-14 Fixed a bug in pyqt4 subplots-adjust. Thanks to
Xavier Gnata for the report and suggested fix - DSD
2007-08-13 Use pickle to cache entire fontManager; change to using
font_manager module-level function findfont wrapper for
the fontManager.findfont method - EF
2007-08-11 Numpification and cleanup of mlab.py 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 matplotlib.__init__.py.
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
config.__init__.py.
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 mathtext.py, 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,
eg. $\mathcal{R}$.
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, eg. $x^i_j$
and $x_j^i$ are equivalent.
- Double sub/superscripts (eg. $x_i_j$) 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
TeX.
- 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 pyparsing.py 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.
