The animation code is currently not fully implemented in the MacOSX backend
because the way the general framework of animations is set up in Matplotlib (at
least last time I checked) is not compatible with drawing on Mac OS X. In
particular, the problem is that on Mac OS X all drawing should be done from
inside the event loop; the animations code also tries to draw outside of the
event loop. Somebody would have to go through the animations code in matplotlib
to sort this out. See e.g. this previous thread on the devel mailing list:

Subject: [Matplotlib-users] Animation example error on Mac after installation
To: matplotlib-users@lists.sourceforge.net

Greetings,
I just installed matplotlib on my Mac OS 10.6 Machine (64bit) with default
Python 2.7.1 (easy_install). While the initial 2D graph examples work great,
when testing any of the animations, such as:
http://matplotlib.sourceforge.net/examples/animation/simple_anim.html
I always get the same error:
File
"/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/matplotlib/animation.py",
line 248, in _blit_clear
a.figure.canvas.restore_region(bg_cache[a])
AttributeError: 'FigureCanvasMac' object has no attribute 'restore_region'
Since "restore_region" is only in backend_agg.py and not in backend_macosx.py,
After reading more on this, I thought this might be corrected by re-installing
from source and setting the setup.cfg to macosx = True and backend = MacOSX
prior to building, but this did not correct the issue. Also, changing backend:
Agg to backend: MacOSX in:
/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/matplotlib/mpl-data/matplotlibrc
didn't work either. Does anyone have experience with this or further insight?
Thanks,
Nathan
