Hi there,
I'm trying to render text with LaTeX using the example on page 53 of the
Matplotlib tutorial; see source code and output below.
It's not working. divipng, (latest)Ghostscript, and LaTeX are all
installed; their executables
in my PATH. Matplotlib is working flawlessly. Help is appreciated.
Thanks, Harry
