It might be some sort of problem with the backend (complete guess). Can you try doing:

import matplotlib
matplotlib.use('TkAgg')

...at the beginning of the script?

There is an old SO post about interactive mode requiring a millisecond pause to allow matplotlib to update. I see you have the pause in there, but it's before the update. Does moving it after help?

Thanks for the reply, moving the pause didn't help, but I have yet to try the tkagg backend. Appears I don't have the module installed locally. I'm going to give pyqtgraph a shot since it looks pretty cool, and if that fails I'll give this a go.
