matplotlib-users Mailing List for matplotlib

The problem was the OpenSuSE 10.1 pre-built RPM.
Rebuilt a release from the latest 0.90 source and it works.

Hello,
I want to use matplotlib to visualize of 2 dimensional mesh (more particulary
adataptive mesh, it looks like this :
http://www.cita.utoronto.ca/~ljdursi/research/curve-region-oct.png).
It consists of a square or a rectangle splitted in square of the same area, each
square can be divided in four over squares and one or more of these four over
squares can be divided in four over squares ... (and this process is achieved
recursively depends of your refinement level).
I have a list which contains the coordinates of the center of each squares and I
want to use these points do draw the mesh. I tried to use matplotlib with
meshgrid
to display the mesh like in the link given before but I didn't succeeded.
My questions are :
Is matplotlib the right library to do this ? and for a positive answer how I can
 do it ?
Thanks
Alex

With a backend configured to be TkAgg, I get the following error on 
startup, i.e. on doing ...
$ python

Can anybody tell me what have I forgotten?
I have the following RPMs installed 
agg-2.4-15.3
quagga-0.98.5-17.5
python-matplotlib-0.87.7-0.pm.1
python-qt-3.5.1-19
python-opengl-2.0.1.09-20
python-doc-pdf-2.4.2-16
python-numeric-24.2-14
python-tk-2.4.2-18
python-openssl-0.6-17
libxml2-python-2.6.23-15
python-logilab-common-0.13.0-14
python-cairo-1.0.2-14
pythoncad-DS1_R27-15
python-numpy-1.0.1-0.pm.1
python-2.4.2-18
python-elementtree-1.2.6-18
python-imaging-1.1.5-17
python-idle-2.4.2-18
python-urlgrabber-2.9.7-15
python-gdbm-2.4.2-18
python-pyx-0.8.1-14
python-gtk-2.8.2-21
kdebindings3-python-3.5.1-19
rpm-python-4.4.2-40
subversion-python-1.3.0-20
By the way, I can reset the backend to 'Agg' and do 
	from pylab import *
	t = arange(10)
	plot(t, t * t)
	savefig('example.png')
and this works.
