Hi Mike,
Have you tried blitting? That prevents the draw from redrawing
everything on the plot, allowing it to only redraw the single line
that's moving, which should help any issues with speed. See some of
the examples <http://matplotlib.org/examples/animation/index.html>
with FuncAnimation and also a Q&A using the draw method here
<https://stackoverflow.com/questions/8955869/why-is-plotting-with-matplotlib-so-slow/8956211#8956211>,
which might work more smoothly with QTimer.

Thanks, I'll check it out. Note that I did get FuncAnimation to work
perfectly well except I have little control over the timing so I had a
hard time synchronizing it with the sound. The FuncAnimation example I
looked at wasn't very helpful if the question is how to blit or other
details, because that's all going on behind the scenes. I will study the
Stack Overflow Q&A and see if there is something I can directly use.
Mike
