I have no experience with matplotlib other than having played with a few 
of the examples.  I have the current versions from MacPorts installed 
(1.1.1 with MacPorts numpy 1.6.2 and MacPorts python 2.7.3, no wxPython, 
all on 10.8.1) and, FWIW, I see the same behavior running your example 
as you report.
