matplotlib-announce Mailing List for matplotlib

This is (hopefully) a final rollup of what is (should be) a fairly
stable tree.  Mainly I wanted to send a release notification out to
the larger python community (scipy/numpy/python-list) since I haven't
done that since 0.60 (July 2004).  

For the major releases, I tend to try and shy away from new features
preferring a stable src.  But for you hardened, grizzled matplotlib
veterans, there are a few enticements nonetheless

 - pie charts and new example/pie_demo.py.  See
   http://matplotlib.sf.net/screenshots.html#pie_demo

 - support for object picking - see examples/picker_demo.py.  As
   people test this out and we settle on an interface, this will
   probably become part of the core, as will other keypress
   functionality for navigation, grid toogle, zoom toggle etc.

 - Fixed coords notification in wx toolbar 

 - key press and release event supported across backends -- see
   examples/keypress_demo.py

 - added Shadow patch class to provide a shadow effect for polygons,
   legends, pie charts -
   http://matplotlib.sf.net/screenshots.html#legend_demo

 - new examples/text_rotation.py demonstrates how text rotations and
   alignment work in matplotlib.  

Bug fixes

  - Fixed PS mathtext bug where color was not set

  - Fixed an agg text rotation alignment bug, fixed some text kwarg
    processing bugs

  - Refactored event handling - multiple connects and disconnects now
    work across backends.  See examples/coords_demo.py, especially
    with test_disconnect

  - Fixed a tkagg interactive bug that caused segfaults in some
    conditions.

This is primarily a bug-fix release from 0.65, though a couple of
little features managed to sneak in

 - 4x image speedups for large images

 - figimage bug fixed

 - fixed some bugs which caused the colorbar not to update properly
   when changing colormap interactively

 - refactored axes management to support delaxes, which deletes, as
   opposed to clears, a specified axes.  Default to current axes

 - tkagg's classic and new-fangled toolbars are now embeddable.

 - extended the new set/get introspection features to more classes

 - fixed some tkagg flakiness on win32 regarding unusual uses of show.

 - new cross backend animation idiom in examples/anim.py - use
   interactive mode rather than timers/idle handlers.

 - deferred some initializations in dates and colors modules for
   faster load times.

 - matlab namespace renamed pylab - see
   http://matplotlib.sf.net/matplotlib_to_pylab.py for details on
   conversion.  ipython pylab users should grab version 0.6.6.  You
   can import the matlab interface (now known as pylab interface) with

   from pylab import blah              # OK
   from matplotlib.pylab import blah   # OK
   from matplotlib.matlab import blah  # Deprecated

 - contouring with the contour function!!  Thanks to Nadia Dencheva.
   See examples/contour_demo.py

 - matlab compatible set and get introspection to determine settable
   properties and their values.  See examples/set_and_get.py.  Sample
   usage

   >>> lines = plot([1,2,3])  
   >>> set(lines)
       alpha: float
       antialiased or aa: [True | False]
       ...snip lots more...
   >>> get(lines)
       alpha = 1.0
       antialiased or aa = True
       ...snip lots more...

 - Added many new matlab compatible colormaps - autumn bone cool
   copper flag gray hot hsv jet pink prism spring summer winter -
   Thanks Perry!

 - zorder to artists to control drawing order of lines, patches and
   text in axes.  See examples/zorder_demo.py 

 - mathtext in cairo backend.  Also, printing now works to file
   object.  Thanks Steve Chaplin.


 - printing in WX - Matthew Newville contributed a print button and
   preview for the wx backends.  He also, who graciously volunteered
   to be the new wx backend maintainer.

 - matlab interface functions connect and disconnect replace
   mpl_connect and mpl_disconnect for event handling

 - Pass hold=True|False to any plotting command to override the
   current hold setting.  The original hold setting will be restored
   at the end of the plot function

 - all text instances now have a bbox property which is a dict of
   Rectangle properties.  If set, the text instance will display in a
   rectanglular bounding box.  Example usage
    
    title('hi mom', bbox={'facecolor':'r', 'alpha':0.5})

 - legend properties now exposed as kwargs.  See help(legend)

 - ishold to inspect the hold state

 - new plotting functions spy, spy2 for matrix sparsity visualization

 - pylab interface functions rgrids and thetagrids for customizing
   the grid locations and labels for polar plots - see
   examples/polar_demo.py.

 - add ion, ioff and isinteractive to pylab interface for control of
   interactive mode.  See updated discussion at
   http://matplotlib.sf.net/interactive.html

Bugs fixed - 

  - Fixed colorbar bug with scatter - JDH

  - SVG clipping problem - Thanks Norm Peterson

  - numerous small legend bugs fixed

  - zoom to rect works with reversed axis limits - thanks Gregory

  - fontsizing problem fixes, ps plots correctly sized, landscape
    support for ps output

  - smaller, leaner, meaner PS output - Thanks Jochen

  - make the Gtk backends build without an X-server connection -
    Thanks Jochen

Dear John
The .exe file for windows insallation does not work
with python 2.4.
Will a new one be released within the next couple of
weeks, or is there another way out of this problem?
Kindest regards
Cosby
