Hello,
for a interactive gui program i want to change the shown data without changing
the rest of the figure. For normal plots, there is a set_xdata/set_ydata
methods. For QuadMesh, there is a set_array method, which i don't get to work.

Thanks,
Till

You have to use ravel(). Illustrated with ipython -pylab:

xx = pcolormesh(rand(3,3))
xx.set_array(rand(3,3).ravel())
draw()
xx.set_array(rand(3,3).ravel())
draw()
