2007-11-13 All backends now support writing to a file-like object, not
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
config file. If a backend is defined in setup.cfg, that will
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
read into a dict called "options" by setupext.py. Also, added
"-mpl" tags to the version strings for packages provided by
matplotlib. Versions provided by mpl will be identified and
updated on subsequent installs - DSD
2007-11-12 Added support for STIX fonts. A new rcParam,
mathtext.fontset, can be used to choose between:
'cm':
The TeX/LaTeX Computer Modern fonts
'stix':
The STIX fonts (see stixfonts.org)
'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.
- MGD
2007-11-12 Options to disable building backend extension modules moved
from setup.py to setup.cfg - DSD
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
system pyparsing, API is too variable from one release
to the next - DSD
2007-11-08 Made pylab use straight numpy instead of oldnumeric
by default - EF
2007-11-08 Added additional record array utilites to mlab (rec2excel,
rec2gtk, rec_join, rec_append_field, rec_drop_field) - JDH
2007-11-08 Updated pytz to version 2007g - DSD
2007-11-08 Updated pyparsing to version 1.4.8 - DSD
2007-11-08 Moved csv2rec to recutils and added other record array
utilities - JDH
2007-11-08 If available, use existing pyparsing installation - DSD
2007-11-07 Removed old enthought.traits from lib/matplotlib, added
Gael Varoquaux's enthought.traits-2.6b1, which is stripped
of setuptools. The package is installed to site-packages
if not already available - DSD
2007-11-05 Added easy access to minor tick properties; slight mod
of patch by Pierre G-M - EF
2007-11-02 Commited Phil Thompson's patch 1599876, fixes to Qt4Agg
backend and qt4 blitting demo - DSD
2007-11-02 Commited Phil Thompson's patch 1599876, fixes to Qt4Agg

2007-10-31 Made log color scale easier to use with contourf;
automatic level generation now works. - EF
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.

Also made unit/memleak_gui.py more flexible with
command-line options. - EF
2007-06-30 Split defaultParams into separate file rcdefaults (together with
validation code). Some heavy refactoring was necessary to do so,
but the overall behavior should be the same as before. - NN
2007-06-27 Added MPLCONFIGDIR for the default location for mpl data

HOME is not writable. Tried to clean up the logic in
_get_config_dir to support non-writable HOME where are
writable HOME/.matplotlib already exists - JDH

2007-04-07 Fixed legend/LineCollection bug. Added label support
to collections. - EF
2007-04-06 Removed deprecated support for a float value as a gray-scale;
now it must be a string, like '0.5'. Added alpha kwarg to
ColorConverter.to_rgba_list. - EF
2007-04-06 Fixed rotation of ellipses in pdf backend

set_bounds() for formatters and locators. - EF
2007-04-02 Fixed problem with imshow and matshow of integer arrays;
fixed problems with changes to color autoscaling. - EF
2007-04-01 Made image color autoscaling work correctly with

unconditionally, while norm.autoscale_None changes
only None-valued vmin, vmax. - EF
2007-03-31 Added a qt-based subplot-adjustment dialog - DSD
2007-03-30 Fixed a bug in backend_qt4, reported on mpl-dev - DSD
2007-03-26 Removed colorbar_classic from figure.py; fixed bug in
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
interface. JDH
2007-03-25 Fix masked array handling in quiver.py for numpy. (Numeric
and numarray support for masked arrays is broken in other
ways when using quiver. I didn't pursue that.) - ADS
2007-03-23 Made font_manager.py close opened files. - JKS
2007-03-22 Made imshow default extent match matshow - EF
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/xcorr_demo.py. Thanks Sameer for the patch. -
JDH
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
is now different

2007-03-03 Change barh to take a kwargs dict and pass it to bar.
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 _wxagg.so 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
constructor.
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.
setup.py 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.
- setup.py: Added the directory pdfcorefonts to package_data.
- lib/matplotlib/__init__.py: Added the default parameter
'pdf.use14corefonts'. When True, the PDF backend uses
only the 14 PDF core fonts.
- lib/matplotlib/afm.py: Added some keywords found in
recent AFM files. Added a little workaround to handle
Euro symbol.
- lib/matplotlib/fontmanager.py: 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
to CODING_GUIDE.
- lib/matplotlib/backends/backend_pdf.py:
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.
-JKS (patch by Nicolas Grilly)
2007-02-17 Changed ft2font.get_charmap, and updated all the files where
get_charmap is mentioned - ES
2007-02-13 Added barcode demo- JDH
2007-02-13 Added binary colormap to cm - JDH
2007-02-13 Added twiny to pylab - JDH
2007-02-12 Moved data files into lib/matplotlib so that setuptools'
develop mode works. Re-organized the mpl-data layout so
that this source structure is maintained in the
installation. (I.e. the 'fonts' and 'images'
sub-directories are maintained in site-packages.) Suggest
removing site-packages/matplotlib/mpl-data and
~/.matplotlib/ttffont.cache before installing - ADS
2007-02-07 Committed Rob Hetland's patch for qt4: remove
references to text()/latin1(), plus some improvements
to the toolbar layout - DSD
===============================================================
2007-02-06 Released 0.90.0 at revision 3003
2007-01-22 Extended the new picker API to text, patches and patch
collections. Added support for user customizable pick hit
testing and attribute tagging of the PickEvent - Details
and examples in examples/pick_event_demo.py - JDH
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; eg, a Line2D can set
the indices attribute that shows the indices into the line
that are within epsilon of the pick point. See
examples/pick_event_demo.py. 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
2007-01-16 src/_image.cpp: update to use Py_ssize_t (for 64-bit systems).
Use return value of fread() to prevent warning messages - SC.
2007-01-15 src/_image.cpp: combine buffer_argb32() and buffer_bgra32() into

examples/contour_demo.py looks correct - SC
2007-01-12 backend_cairo.py: fix draw_image() so that examples/image_demo.py
now looks correct - SC
2007-01-11 Added Axes.xcorr and Axes.acorr to plot the cross
correlation of x vs y or the autocorrelation of x. pylab
wrappers also provided. See examples/xcorr_demo.py - 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
2006-12-27 backend_cairo.py: update draw_image() and _draw_mathtext() to work
with numpy - SC
2006-12-20 Fixed xpdf dependency check, which was failing on windows.
Removed ps2eps dependency check. - DSD
2006-12-19 Added Tim Leslie's spectral patch - JDH
2006-12-17 Added rc param 'axes.formatter.limits' to control
the default threshold for switching to scientific
notation. Added convenience method
Axes.ticklabel_format() for turning scientific notation
on or off on either or both axes. - EF
2006-12-16 Added ability to turn control scientific notation
in ScalarFormatter - EF
2006-12-16 Enhanced boxplot to handle more flexible inputs - EF
2006-12-13 Replaced calls to where() in colors.py with much faster
clip() and putmask() calls; removed inappropriate
uses of getmaskorNone (which should be needed only
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
2006-12-09 Added support for plotting 2-D arrays with plot:
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 colors.py as illustrated by
examples/pcolor_log.py, based on suggestion by
Jim McDonald. Colorbar modified to handle LogNorm.
Norms have additional "inverse" method. - EF
2006-12-02 Changed class names in colors.py to match convention:
normalize -> Normalize, no_norm -> NoNorm. Old names
are still available.
Changed __init__.py 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/clippedline.py, which shows how to clip line

style when zoomed in - JDH
2006-11-21 Some spy bug-fixes and added precision arg per Robert C's
suggestion - JDH
2006-11-19 Added semi-automatic docstring generation detailing all the
kwargs that functions take using the artist introspection
tools; eg 'help text now details the scatter kwargs
that control the Text properties - JDH
2006-11-17 Removed obsolete scatter_classic, leaving a stub to
raise NotImplementedError; same for pcolor_classic - EF
2006-11-15 Removed obsolete pcolor_classic - EF
2006-11-15 Fixed 1588908 reported by Russel Owen; factored
nonsingular method out of ticker.py, put it into
transforms.py as a function, and used it in
set_xlim and set_ylim. - EF
2006-11-14 Applied patch 1591716 by Ulf Larssen to fix a bug in
apply_aspect. Modified and applied patch
1594894 by mdehoon to fix bugs and improve
formatting in lines.py. Applied patch 1573008
by Greg Willden to make psd etc. plot full frequency
range for complex inputs. - EF
2006-11-14 Improved the ability of the colorbar to track
changes in corresponding image, pcolor, or
contourf. - EF
2006-11-11 Fixed bug that broke Numeric compatibility;
added support for alpha to colorbar. The
alpha information is taken from the mappable
object, not specified as a kwarg. - EF
2006-11-05 Added broken_barh function for makring a sequence of
horizontal bars broken by gaps -- see examples/broken_barh.py
2006-11-05 Removed lineprops and markerprops from the Annotation code
and replaced them with an arrow configurable with kwarg
arrowprops. See examples/annotation_demo.py - JDH
2006-11-02 Fixed a pylab subplot bug that was causing axes to be
deleted with hspace or wspace equals zero in
subplots_adjust - JDH
2006-10-31 Applied axes3d patch 1587359

===============================================================
2006-10-26 Released 0.87.7 at revision 2835
2006-10-25 Made "tiny" kwarg in Locator.nonsingular much smaller - EF
2006-10-17 Closed sf bug 1562496 update line props dash/solid/cap/join
styles - JDH
2006-10-17 Complete overhaul of the annotations API and example code -
See matplotlib.text.Annotation and
examples/annotation_demo.py JDH
2006-10-12 Committed Manuel Metz's StarPolygon code and
examples/scatter_star_poly.py - JDH
2006-10-11 commented out all default values in matplotlibrc.template
Default values should generally be taken from defaultParam in
__init__.py - 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 figimage_demo.py
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: simple3d.py - 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
2006-09-29 added two options to matplotlibrc:
svg.image_inline
svg.image_noscale
see patch #1533010 for details - NN
2006-09-29 axes.py: cleaned up kwargs checking - NN
2006-09-29 setup.py: cleaned up setup logic - NN
2006-09-29 setup.py: check for required pygtk versions, fixes bug #1460783 - SC
===============================================================
2006-09-27 Released 0.87.6 at revision 2783
2006-09-24 Added line pointers to the Annotation code, and a pylab
interface. See matplotlib.text.Annotation,
examples/annotation_demo.py and
examples/annotation_demo_pylab.py - JDH
2006-09-18 mathtext2.py: The SVG backend now supports the same things that
the AGG backend does. Fixed some bugs with rendering, and out of
bounds errors in the AGG backend - ES. Changed the return values
of math_parse_s_ft2font_svg to support lines (fractions etc.)
2006-09-17 Added an Annotation class to facilitate annotating objects
and an examples file examples/annotation_demo.py. I want
to add dash support as in TextWithDash, but haven't decided
yet whether inheriting from TextWithDash is the right base
class or if another approach is needed - JDH
===============================================================
2006-09-05 Released 0.87.5 at revision 2761
2006-09-04 Added nxutils for some numeric add-on extension code --
specifically a better/more efficient inside polygon tester (see
unit/inside_poly_*.py) - JDH
2006-09-04 Made bitstream fonts the rc default - JDH
2006-08-31 Fixed alpha-handling bug in ColorConverter, affecting
collections in general and contour/contourf in
particular. - EF
2006-08-30 ft2font.cpp: Added draw_rect_filled method (now used by mathtext2
to draw the fraction bar) to FT2Font - ES
2006-08-29 setupext.py: wrap calls to tk.getvar() with str(). On some
systems, getvar returns a Tcl_Obj instead of a string - DSD
2006-08-28 mathtext2.py: Sub/superscripts can now be complex (i.e.
fractions etc.). The demo is also updated - ES
2006-08-28 font_manager.py: Added /usr/local/share/fonts to list of
X11 font directories - DSD
2006-08-28 mahtext2.py: Initial support for complex fractions. Also,
rendering is now completely separated from parsing. The
sub/superscripts now work better.
Updated the mathtext2_demo.py - ES
2006-08-27 qt backends: don't create a QApplication when backend is
imported, do it when the FigureCanvasQt is created. Simplifies
applications where mpl is embedded in qt. Updated
embedding_in_qt* examples - DSD
2006-08-27 mahtext2.py: Now the fonts are searched in the OS font dir and
in the mpl-data dir. Also env is not a dict anymore. - ES
2006-08-26 minor changes to __init__.py, mathtex2_demo.py. Added matplotlibrc
key "mathtext.mathtext2" (removed the key "mathtext2") - ES
2006-08-21 mathtext2.py: Initial support for fractions
Updated the mathtext2_demo.py
