This seems like a mac problem, Larry reported the same problem with
0.3.6 (without matplotlib) but not with 0.4.0

Sorry but I don't have a mac, so it's hard for me to fix this.

that's because qwt is not found - so it uses matplotlib. If qwt is not
found, but matplotlib is, then it uses qwt and there is no choice.

I didn't really look into the performance of matplotlib vs. qwt

I'll look into that - probably related to the bug you experience.
