Thread: [Matplotlib-users] Color Map.

Hello
folks,



I´m a new user of this forum. I'm trying to work in Python at the moment but
it´s quite difficult for me. My first question is if it is possible to do Color
Maps in Matplotlib in the same manner of the "mesh" function in
Matlab. Could you help me anybody?



Thanks in advance.



Regards.

Hi Oscar,

Matplotlib is a purely 2D plotting library, it doesn't provide similar
capability to the Matlab 'mesh' function. For 3D plotting you could
use Mayavi

You can probably still get great visualization of your results using
the Matplotlib functions pcolor, pcolormesh, contour, contourf or
imshow. See the documentation and examples at these links to get
started.

Also look at the pyplot tutorial and post to the list if you get stuck.

Since you're just starting out, I'd take a look at:

http://matplotlib.sourceforge.net/gallery.html

to get a feel for what's possible with matplotlib.  It sounds like what you're
interested would be pcolor/pcolormesh.
