Also, is it possible to change the stride color/opacity?  Not for this plot
in particular, but for surface plots, I'd rather not have dense black
strides on my surface.  Can't find the right keyword call through the 3d
API.  Sorry if I'm overlooking something obvious in the docs

I would like to place a mathematical symbol on a plot by using the appropriate 
code bracketed by dollar signs, e.g., $\alpha$. This is the technique used in 
the program  pyplot_mathtext.py described at 
http://matplotlib.org/users/mathtext.html#mathtext-tutorial. When I run this 
probram I get the error messages shown below. What do I need to do to fix this 
problem? I'm using matplotlib 1.3.1 and Python 2.6.

>python pyplot_mathtext.py
