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

clipping to clip the lines a nd grids to the polar axes.

Added support for set_rmax to easily change the maximum

radial grid. Added support for polar legend - JDH

2007-04-16 Added Figure.autofmt_xdate to handle adjusting the bottom

and rotating the tick labels for date plots when the ticks

often overlap - JDH

2007-04-09 Beginnings of usetex support for pdf backend. -JKS

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

(sf bug #1690559) -JKS

2007-04-04 More matshow tweaks; documentation updates; new method

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

a tracking colorbar; norm.autoscale now scales

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

2007-03-20 Refactored units support and added new examples - JDH

2007-03-19 Added Mike's units patch - JDH

2007-03-18 Matshow as an Axes method; test version matshow1() in

2007-03-14 Add masked-array support to hist. - EF

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

data based on view limits -- it also changes the marker

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

JDH

===============================================================

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

===============================================================

2006-07-11 Released 0.87.4 at revision 2558

2006-07-07 Fixed a usetex bug with older versions of latex - DSD

2006-07-07 Add compatibility for NumPy 1.0 - TEO

2006-06-29 Added a Qt4Agg backend. Thank you James Amundson - DSD

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

2006-06-22 Added support for numerix 2-D arrays as alternatives to

a sequence of (x,y) tuples for specifying paths in

collections, quiver, contour, pcolor, transforms.

Fixed contour bug involving setting limits for

color mapping. Added numpy-style all() to numerix. - EF

2006-06-20 Added custom FigureClass hook to pylab interface - see

examples/custom_figure_class.py

2006-06-16 Added colormaps from gist (gist_earth, gist_stern,

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, eg in gtk

fig.canvas.manager.window.set_title, though a GUI neutral

method would be preferable JDH

2006-06-16 Fixed colorbar.py 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

2006-06-13 Fix so numpy updates are backward compatible - TEO

2006-06-12 Updated numerix to handle numpy restructuring of

oldnumeric - TEO

2006-06-12 Updated numerix.fft to handle numpy restructuring

Added ImportError to numerix.linear_algebra for numpy -TEO

2006-06-11 Added quiverkey command to pylab and Axes, using

QuiverKey class in quiver.py. Changed pylab and Axes

to use quiver2 if possible, but drop back to the

newly-renamed quiver_classic if necessary. Modified

examples/quiver_demo.py to illustrate the new quiver

and quiverkey. Changed LineCollection implementation

slightly to improve compatibility with PolyCollection. - EF

2006-06-11 Fixed a usetex bug for windows, running latex on files

with spaces in their names or paths was failing - DSD

2006-06-09 Made additions to numerix, changes to quiver to make it

work with all numeric flavors. - EF

2006-06-09 Added quiver2 function to pylab and method to axes,

with implementation via a Quiver class in quiver.py.

quiver2 will replace quiver before the next release;

it is placed alongside it initially to facilitate

testing and transition. See also

examples/quiver2_demo.py. - EF

2006-06-08 Minor bug fix to make ticker.py draw proper minus signs

with usetex - DSD

===============================================================

can take any mpl color arg or sequence of args; deprecated

float as grayscale, replaced by string representation of

float. - EF

2006-05-19 Added custom symbol option to scatter - JDH

2006-05-18 New example, multi_image.py; colorbar fixed to show

offset text when the ScalarFormatter is used; FixedFormatter

augmented to accept and display offset text. - EF

2006-05-14 New colorbar; old one is renamed to colorbar_classic.

New colorbar code is in colorbar.py, with wrappers in

figure.py and pylab.py.

Fixed aspect-handling bug reported by Michael Mossey.

Made backend_bases.draw_quad_mesh() run.- EF

2006-05-08 Changed handling of end ranges in contourf: replaced

"clip-ends" kwarg with "extend". See docstring for

details. -EF

2006-05-08 Added axisbelow to rc - JDH

2006-05-08 If using PyGTK require version 2.2+ - SC

directory, rather than in the user's current working

directory - DSD

2006-04-05 Apllied Ken's wx deprecation warning patch closing sf patch

#1465371 - JDH

2006-04-05 Added support for the new API in the postscript backend.

Allows values to be masked using nan's, and faster file

creation - DSD

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

2006-04-03 Fixed the bug in which widgets would not respond to

events. This regressed the twinx functionality, so I

also updated subplots_adjust to update axes that share

an x or y with a subplot instance. - CM

2006-04-02 Moved PBox class to transforms and deleted pbox.py;

made pylab axis command a thin wrapper for Axes.axis;

more tweaks to aspect-ratio handling; fixed Axes.specgram
