problem submitting a job that creates figures

[cod3licious]

when submitting a job to execute a python script that uses matplotlib to create figures, I get the error "Unable to access the X Display, is $DISPLAY set properly?".
I use NX and submitted the job with qsub -V.
$DISPLAY was first 50002.0 but setting "export DISPLAY=ba3.mit.edu:50002.0" did not solve anything.

according to this:

http://matplotlib.sourceforge.net/faq/howto_faq.html#generate-images-without-having-a-window-popup

you want to use a different backend to generate the images so that a X window isn't required.

this is not a python specific issue. might be more of an NX specific issue. try launching xeyes from a qsub -VI interactive session.

it works if I do this: matplotlib.use('Agg') whenever I log onto mh21 with qsub -I -l host=mh21. Haven't tried actually submitting jobs though.
