This may help ... or not ( 2nd part )

try not to do pylab.figure()

in your script:
pylab.plot, or pylab.imshow or whatever you want to use
then
savefig("myFigure.png") for example
do not use show()

in my case ( with the WXAgg backend ), it works, it generates the png file

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.
