'stixsans':

The STIX fonts, using sans-serif glyphs by default

'custom':

A generic Unicode font, in which case the mathtext font

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

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.

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

2007-03-03 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
