[Matplotlib-announce] ANN: matplotlib 0.83.2

[John H. <jdh...@ac...>]

This is the second bug fix release of the 0.83 series, but a couple of
new features have crept in....  The notes below include all new
features in 0.83; I've just been a little slow getting them typed up
:-)

You can read these with links at

What's new in matplotlib 0.83

axis('scale')

  Added Mark Athen's 'scale' patch, so that on a scaled axis a circle
  looks like circle. See help(axis).

New cursor and span selector widgets

  Added new Cursor and HorizontalSpanSelector to
  matplotlib.widgets. See examples/widgets/cursor.py and
  examples/widgets/span_selector.py. Set useblit = True on gtkagg for
  significantly enhanced performance.

draw events

  You can use use matplotlib event handling to register a callback
  after figure draw using 'draw_event' which calls the callback with a
  DrawEvent instance

  def callback(event):
     #event.renderer is the backend Renderer instance
     pass
  connect('draw_event')


Full screen mode in GTK*

  Use 'f' to toggle full screen mode in the GTK backends.  

GTK and SVG fixes

  Steve Chaplin has made numerous updates to the GTK and SVG
  backends. See the CHANGELOG for details.

Reorganized config files

  Made HOME/.matplotlib the new config dir where the matplotlibrc
  file, the ttf.cache, and the tex.cache live. The new default
  filenames in .matplotlib have no leading dot and are not hidden. Eg,
  the new names are matplotlibrc, tex.cache, and ttffont.cache. This
  is how ipython does it so it must be right. If old files are found,
  a warning is issued and they are moved to the new location. Also
  fixed texmanager to put all files, including temp files in
  ~/.matplotlib/tex.cache, which allows you to usetex in non-writable
  dirs.

Using matplotlib.agg to draw paths

  Updated agg_test.py to demonstrate curved paths and fills.

CocoaAgg

  New CocoaAgg backend for native GUI on OSX, 10.3 and 10.4 compliant.

Qt enhancements

  Applied Ted Drain's QtAgg patch: 1) Changed the toolbar to be a
  horizontal bar of push buttons instead of a QToolbar and updated the
  layout algorithms in the main window accordingly. This eliminates
  the ability to drag and drop the toolbar and detach it from the
  window. 2) Updated the resize algorithm in the main window to show
  the correct size for the plot widget as requested. This works almost
  correctly right now. It looks to me like the final size of the
  widget is off by the border of the main window but I haven't figured
  out a way to get that information yet. We could just add a small
  margin to the new size but that seems a little hacky. 3) Changed the
  x/y location label to be in the toolbar like the Tk backend instead
  of as a status line at the bottom of the widget. 4) Changed the
  toolbar pixmaps to use the ppm files instead of the png files. I
  noticed that the Tk backend buttons looked much nicer and it uses
  the ppm files so I switched them.

mathtext optimizations

  Upgraded pyparsing and applied Paul McGuire's suggestions for
  speeding things up. This more than doubles the speed of mathtext in
  my simple tests.

Bugs fixed / small features 

  Applied SF patches 1242648, 1244732. Fixes SF bugs 1238412, 1231611,
  1209354, subplot (2,1,1) bug,
