Hi Bala, you may want to have a look at the gallery including many example pictures on http://matplotlib.sourceforge.net/gallery.html especially the follwing two examples might be of interest for you http://matplotlib.sourceforge.net/examples/pylab_examples/contourf_demo.html http://matplotlib.sourceforge.net/examples/api/colorbar_only.html
I used these two to set up the attached example, which is very close to what you want. Question for developers: Could it be useful to add two kwargs 'over_color' and 'under_color' to contourf in order to allow specification of a ListedColormap by kwarg 'colors' and these two colors? best regards Matthias On Thursday 09 April 2009 10:34:27 Bala subramanian wrote: > Dear Matthias, > > Thanks a ton.
