Nice find! Did you try other back-ends with MPL on Ubuntu (maybe Qtagg)?
GTK was recommended for Windows, but adding plt.pause(0.1) helped event handlers get process time (see #5).

@breznak Maybe we should add this to the README or just enable the wiki?

@rhyolight ...what suits you better, just it should be mentioned somewhere.
@rcrowder I tried other backends, Qt,GTK,.. had some trouble still.

@breznak matplotlib needs to be used in a certain why when interactively updating it with data. Adding the millisecond pause is a hack to help background processing. It's still useful at a graphing tool. But then we now have nupic.visualizations and Marcus/Felix work too :)

Yes, I want to move away from matplotlib and towards some web-base charting as soon as live charts are ready in nupic.visualization.
