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.
