[yt-users] X11 issues with yt

[j s oishi]

Yup. I just wanted to add that the caps do indeed matter, and make
sure the matplotlib.use('Agg') comes *before* the import pylab
statement.

You can also select the backend on the command line:

python myscript.py -dAgg

should have the same effect. This makes matplotlib use the non-X11 Agg backend.
