You can either send them the link to this discussion, or just the little snippet concerning gcf() above; just taking care of that would be an improvement.
That did the trick. I tried going through the source code but it just got too messy. How do I let the networkx developers know about this?

I am currently trying to have two panels each with their own figure instance so they can have separate plots.
I can successfully update a plot if there is only one panel. As soon as I add a second panel, I get the following error when I try to update (replot) a plot (Showing last message only):
File "/Library/Frameworks/Python.framework/Versions/7.3/lib/python2.7/site-packages/matplotlib/axes.py", line 1374, in _sci

I looked online first and one site suggested it was because I was using matplotlib.Figure instead of pylab.Figure. I switched and the problem still occurs. I was curious to see if this problem had to do with how I set up my program, not with matplotlib, so I wrote a little test program. The exact same problem occurs. I have attached the test program. To see that it does work with just one panel comment out lines 39, 41, and 49. When put back in, I get the above error message.
Any suggestions as to how to fix this?
Can you please post the entire traceback? My suspicion for what is happening is that both figures are sharing the same canvas, but I am not exactly sure. Anyway, when you perform a plot on one panel, you are calling "clear()" for that figure, which may be having side-effects for the other figure since it is attached to the same Wx object.
Actually, looking over your code again, I see a few things that may or may not be part of the problem, but should be addressed, nevertheless. First, you are calling FigureCanvas and assigning it to self.canvas. This canvas is different from the canvas that the figure will actually use, so I am not sure if this is being done correctly. Second, your call to "plt.close()" assumes that the figure you want to close is the currently active figure. What you want to call is "plt.close(self.figure)" in order to make sure it closes the figure you intend to close.
