[SciPy-User] density map?

[Sebastian Bassi]

Hello,

I have a 2-D Numpy array with intensity data.
I'd like to plot it like this
http://crocdoc.ifas.ufl.edu/images/posters/ecologyofgatorholes/9_figure6.gif
For each value in a position, it will be colored with a color, if the
value is higher the color will be more intense (maybe from blue to
red).
All examples I found on http://www.scipy.org/Cookbook/Matplotlib/ were
using functions instead of data from a matrix/array.
Any idea?
Best,
SB.
