I normally develop with wxPython, which is fully event driven - I 
write a lot of interactive spectrograms etc.

3D plots in MPL are horribly slow for 1kx2k waterfalls or 
spectrograms. I switched to openGL / Mayavi (mine is from Enthought).

I have an above derived 3D spectrogram example online:

The initial render is slow with a full array of 2048x785 and hogs 
500MB ram, but once the vertexes etc are in the GPU manipulation is instant.
There is a bug with VTK you need to mod in the install

I'd love to see others' Mayavi 3D code...
