There was a problem hiding this comment.
I wonder if you want to wrap this in a small method with an explanation like your explanation below as the doc string:
def _not_orig_canvas():
"""

""""
return self.canvas is not self.ax.figure.canvas
Perhaps thats too much cruft, but otherwise this is a bit of a mysterious clause.
