Matplotlib in PyQt GUI - Need more FPS

Dear Matplotlib-users,

I have now been struggling with getting matplotlib integrated into a
PyQt based GUI environment. The example

which comes with the source distribution, has been my starting

The problem is that in my own applications, matplotlib has to serve
the purpose of showing animated data; and for some reason, I cannot
squeeze more than 10-15 FPS out of the example. The QTimer in the
example is set to 10 ms, so this is not the problem.

If I implement a simple, and of course, much more simplistic 2D window
in 'raw' PyQt, this easily gives 95 FPS with 1000 datapoints.

Any suggestions and feedbacks on how to approach this problem are more
than welcome.

Best regards,

Mads Ipsen
