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.
