I'm not sure why using ax.bbox does not work, and it SHOULD work. Note that animation_blit_gtk.py DOES use ax.bbox. > Perhaps we should correct the examples. > I can send you the good working example if you want. If using ax.bbox does not work, than it is a bug (either mpl or the example). Unfortunately, this seems to happen only on windows. So, please file a bug report (again).
