Hello,
Maybe my googling skills are deficient, but I wasn't able to find any
information on how to define my own colormap.
Can someone give me a pointer, or a basic example how to create a simple
map that e.g. maps -1 to Red, 0 to White, and 1 to Blue?
Thanks,

That was a tad harsh, given that the first page of google results
didn't really answer the question. (If you're going to be snarky, at
least make sure you're right.)
Nick, this is a pretty good example:
http://matplotlib.sourceforge.net/examples/api/colorbar_only.html
Now, since it seems like you're learning right now, a good place to
look which is better than google is searching matplotlib's docs
directly:
http://matplotlib.sourceforge.net/search.html
I was able to find that example with: codex ListedColormap
(codex tells it to search examples) but that's because I knew the name
of the class I was looking for.
Good luck and don't get discouraged.
Ryan
I don't know what your Google search results page presented, but the the
_*second entry *_on the _*first*_ search results page, for me, was the
following:
Cookbook/Matplotlib -
Feb 12, 2010 ... Show colormaps - Small script to display all of the
Matplotlib colormaps, and _*an exampleshowing how to create a new one*_. ...
www.scipy.org/Cookbook/Matplotlib - Cached
