Thanks that worked ! I changed the backend to Agg.
Allthough a problem there is that with the backend Agg you only can
write the resulting image to a file or a file like object, it does not
accept the (apache) request handler to write the file to. And I do not
want to save the file to disk first before sending to the client.

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.
