================================================================= 2008-12-09 Released 0.98.4 at svn r6536
2008-12-08 Added mdehoon's native macosx backend from sf patch 2179017 - JDH
2008-12-08 Removed the prints in the set_*style commands. Return the
list of pprinted strings instead - 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
by the sampling frequency. This gives better MatLab
compatibility. -RM
2008-12-08 Fixed alignment of ticks in colorbars. -MGD
2008-12-07 drop the deprecated "new" keyword of np.histogram() for
numpy 1.2 or later. -JJL
2008-12-06 Fixed a bug in svg backend that new_figure_manager()
ignores keywords arguments such as figsize, etc. -JJL
2008-12-05 Fixed a bug that the handlelength of the new legend class
set too short when numpoints=1 -JJL
2008-12-04 Added support for data with units (e.g. dates) to
Axes.fill_between. -RM
2008-12-04 Added fancybox keyword to legend. Also applied some changes
for better look, including baseline adjustment of the
multiline texts so that it is center aligned. -JJL
2008-12-02 The transmuter classes in the patches.py are reorganized as
subclasses of the Style classes. A few more box and arrow
styles are added. -JJL
2008-12-02 Fixed a bug in the new legend class that didn't allowed
a tuple of coordinate vlaues as loc. -JJL
2008-12-02 Improve checks for external dependencies, using subprocess
(instead of deprecated popen*) and distutils (for version
checking) - DSD
2008-11-30 Reimplementaion of the legend which supports baseline alignement,
multi-column, and expand mode. - JJL
2008-12-01 Fixed histogram autoscaling bug when bins or range are given
explicitly (fixes Debian bug 503148) - MM
2008-11-25 Added rcParam axes.unicode_minus which allows plain hypen
for minus when False - JDH
2008-11-25 Added scatterpoints support in Legend. patch by Erik
Tollerud - JJL
2008-11-24 Fix crash in log ticking. - MGD
2008-11-20 Added static helper method BrokenHBarCollection.span_where
and Axes/pyplot method fill_between. See
examples/pylab/fill_between.py - JDH
2008-11-12 Add x_isdata and y_isdata attributes to Artist instances,
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
2008-11-09 Fix a possible EINTR problem in dviread, which might help
when saving pdf files from the qt backend. - JKS
2008-11-05 Fix bug with zoom to rectangle and twin axes - MGD
2008-10-24 Added Jae Joon's fancy arrow, box and annotation
enhancements -- see
examples/pylab_examples/annotation_demo2.py
2008-10-23 Autoscaling is now supported with shared axes - EF
2008-10-23 Fixed exception in dviread that happened with Minion - JKS
2008-10-21 set_xlim, ylim now return a copy of the viewlim array to
avoid modify inplace surprises
2008-10-20 Added image thumbnail generating function
matplotlib.image.thumbnail. See
examples/misc/image_thumbnail.py - JDH
2008-10-20 Applied scatleg patch based on ideas and work by Erik
Tollerud and Jae-Joon Lee. - MM
2008-10-11 Fixed bug in pdf backend: if you pass a file object for
output instead of a filename, e.g. in a wep app, we now
flush the object at the end. - JKS
2008-10-08 Add path simplification support to paths with gaps. - EF
2008-10-05 Fix problem with AFM files that don't specify the font's
full name or family name. - JKS
2008-10-04 Added 'scilimits' kwarg to Axes.ticklabel_format() method,
for easy access to the set_powerlimits method of the
major ScalarFormatter. - EF
2008-10-04 Experimental new kwarg borderpad to replace pad in legend,
based on suggestion by Jae-Joon Lee. - EF
2008-09-27 Allow spy to ignore zero values in sparse arrays, based
on patch by Tony Yu. Also fixed plot to handle empty
data arrays, and fixed handling of markers in figlegend. - EF
2008-09-24 Introduce drawstyles for lines. Transparently split linestyles
like 'steps--' into drawstyle 'steps' and linestyle '--'.
Legends always use drawstyle 'default'. - MM
2008-09-18 Fixed quiver and quiverkey bugs (failure to scale properly
when resizing) and added additional methods for determining
the arrow angles - EF
2008-09-18 Fix polar interpolation to handle negative values of theta - MGD
2008-09-14 Reorganized cbook and mlab methods related to numerical
calculations that have little to do with the goals of those two
modules into a separate module numerical_methods.py
Also, added ability to select points and stop point selection
with keyboard in ginput and manual contour labeling code.
Finally, fixed contour labeling bug. - DMK
2008-09-11 Fix backtick in Postscript output. - MGD
2008-09-10 [ 2089958 ] Path simplification for vector output backends
Leverage the simplification code exposed through
path_to_polygons to simplify certain well-behaved paths in
the vector backends (PDF, PS and SVG). "path.simplify"
must be set to True in matplotlibrc for this to work. -
MGD
2008-09-10 Add "filled" kwarg to Path.intersects_path and
Path.intersects_bbox. - MGD
2008-09-07 Changed full arrows slightly to avoid an xpdf rendering
problem reported by Friedrich Hagedorn. - JKS
2008-09-07 Fix conversion of quadratic to cubic Bezier curves in PDF
and PS backends. Patch by Jae-Joon Lee. - JKS
2008-09-06 Added 5-point star marker to plot command - EF

'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.

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

2007-10-29 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.
