[Matplotlib-users] Generating and saving figures without actually displaying them

2007-05-18 Thread kaushik.ghose 
Hello,

I want to run a python program on a remote machine via ssh. It generates 
figures and saves them to files. I don't need/want to see the figures as 
they are being generated and saved.

When I do this on the remote machine (which is running linux) I get a 
display error

_tkinter.TclError: no display name and no $DISPLAY environment variable

Is there a way to disable drawing on the device and just have 'virtual' 
drawing to a file?

thanks!

 Try using the agg backend

Which you can do by either:

  * changing the default backend in .matplotlibrc

or

  * Putting:
import matplotlib
matplotlib.use(Agg)

at the top of your script, BEFORE any mpl calls, including import 
pylab, if indeed you import pylab at all.
