Hi Andreas, Someone else, please correct me if I'm wrong, but I think the only way to do this is to provide your own "facecolors" map. Pick your preferred color map and apply it to dataset B, then now use mplot3d plot_surface(X,Y,Z_A,facecolors=B_colors).
Assuming you are running inside pylab or have done similar imports, the following example should work ------------------------------------------- import mpl_toolkits.mplot3d.axes3d x=arange(10) y=arange(10) x,y=meshgrid(x,y) za=sin(np.deg2rad(x))+20*cos(np.deg2rad(y)) zb=x*25 colors=cm.jet(zb) ax = gca(projection='3d') surf = ax.plot_surface(x,y,za,rstride=1,cstride=1,facecolors=colors) draw() #I'm not sure why the draw command is necessary… anyone? ------------------------------------------- Note, plot_surface will apply shading by default, you can turn it off and just use your supplied colors using the shade=False keyword arg ethan On Oct 27, 2012, at 2:09 AM, Andreas Hilboll wrote: > Hi, maybe matplotlib is capable of doing this: > > I have two gridded datasets, A and B, for say Europe.
