Hello, I have a really dummy question.
I would like to plot an x, y, z table so that each region of the plot
area defined by the coordinates (x, y) corresponds a color given by the
value of z. I suppose this is a kind of basic functionality, but I'm
unable to find the right function into matplotlib API.
Thank you. Cheers,

You probably want imshow, pcolor, pcolormash or matshow
http://matplotlib.sourceforge.net/api/pyplot_api.html#matplotlib.pyplot.imshow
http://matplotlib.sourceforge.net/api/pyplot_api.html#matplotlib.pyplot.pcolor
http://matplotlib.sourceforge.net/api/pyplot_api.html#matplotlib.pyplot.pcolormesh
http://matplotlib.sourceforge.net/api/pyplot_api.html#matplotlib.pyplot.matshow
There's a basic example of using imshow here:

Cheers,

I meant pcolormesh...

Hi, for 2d you can use basic contourf of maptplotlib, or 3d with
contourf3D(X,Y,Z) by using the mplot3d tookit.
see tutorial :
2d :

3d :
