Hi Ken,
You're getting that error because you probably don't have Qt4 installed
on your Mac (I do). I'm not sure what backends come with matplotlib and
will work for you (maybe someone here knows). You can use any of the
following:
GTK GTKAgg GTKCairo CocoaAgg FltkAgg
MacOSX QtAgg Qt4Agg TkAgg WX WXAgg Agg Cairo GDK PS PDF SVG Template
Like Qt4, some of those may need to be installed. I also have Gtk
installed (never used it before) and "GTKAgg" works for me, but not
"GTK". It's also important to know that not all of those backends are
interactive (they don't all show a window) and the figure must be saved
to a file.
Also make sure that the 2 lines I provided need to be BEFORE any other
matplotlib/pyplot imports. Hope you find something that works for you,
at least until the macosx bug is fixed. I'm not an expert, sorry.

Hi, Dave,
I tried the two lines of code you posted, but when I ran the example I
mentioned above I got such error:
ImportError: No module named sip
Seems I can't import any other libs from matplotlib after
"matplotlib.use("Qt4Agg")"
I'm kind of a newbie, sorry.

I experienced the same problem on the macosx backend, switched to
Qt4Agg
and no problems.
import matplotlib
matplotlib.use("Qt4Agg")
