separate figures might be better, if you only can see one or two at a 
time anyway.

still, quick enough when a change is made is different than quick enough 
to scroll.

I think wxAgg might be faster. Drawing in wx has taken a hit with 2.8 on 
the Mac. You can use wxAgg if you disable the accelerator by removing:

/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/matplotlib/backends/_wxagg.so

Then wxAgg should work, with the pure python version. Give it a try and 
see what you think.

There's a better version for 2.8 in SVN, but it hasn't made it into a 
release yet.
