OK, I mostly understand John's example and have adapted it in the attached Histogram class, for whoever might care. (The file is a working example.) Thanks!
Here are my remaining questions. 1. To get a new histogram, I just change the data in the vertices object and then ask my FigureCanvasTkAgg to ``show`` itself. How does this work? (I suppose that this FigureCanvas has my figure, the figure references my axes, my axes references my PathPatch, and my PathPatch references the rectverts, and each looks to the next when I call show?) 2. This is pretty fast. Would there be additional speed gains to blitting, and if so, how would it be done? (I'm just asking for clues, not a complete example.) I expected to be able to set the animated property on the patch when I called ax.add_patch, but that does not work; am I supposed to just set it directly? (I had supposed that the axes were being informed e.g. when setting animated=True for an ax.plot, but now I'm guessing that supposition is wrong the `plot` just provides this as a convenience.) If I have unveiled some radical misconceptions, sorry, I don't have experience with GUI stuff.
