[Matplotlib-users] Z channel

2010-09-15 Thread Daπid
Does MPL support in any way the Z channel? If not, is there any possibility to use it? For example, to create a parallel matrix of the same dimensions of the image with the values of Z in each pixel. Thank you very much. David.

I think you can make it with pyplot.contourf() and the argument V http://matplotlib.sourceforge.net/api/pyplot_api.html#matplotlib.pyplot.contour "contour(Z,V) contour(X,Y,Z,V) draw contour lines at the values specified in sequence V" On Wed, Sep 15, 2010 at 9:02 PM, Luke wrote: > I have a fun
