This may help you ... or not

You may have to change your backend :

p13 of the matplotlib user guide: backends
p17 how to change the backend in the matplotlibrc

An example of matplotlibrc ( backend choice is at the beginning ):
http://matplotlib.sourceforge.net/matplotlibrc

You may choose PS or SVG or pdf, there might be other possibilities, I do not know
To save the file : savefig

I want to use pylab (matplotlib) on a machine without X11. I'm trying to generate onthefly graphics for an apache2 web service, so they do not have to be displayed on this machine !

When i do
pylab.figure()
I get the error
TclError: couldn't connect to display ":0.0"

I tried setting the DISPLAY environment variable to "", ":0.0" but I got the same error message.

Any help is very much appreciated.
