[Matplotlib-users] how to create a facecolors map?

[vwf <vw...@vu...>]

Hello,

I would like to create a surface with a color provided by an independent
variable. The shape is defined by a matrix  with the z-values. The
color is a matrix of identical shape with floats. Can this be done?
My experiment code is incomplete: I could not write anything useful. Can
onyone help me making it work?

Thank you

cdict = {'red':   ((0.0,  0.0, 0.0),
                   (15.0,  1.0, 1.0)),

         'green': ((0.0,  0.0, 0.0),
                   (15.0,  0.0, 0.0)),

         'blue':  ((0.0,  1.0, 1.0),
                   (15.0,  0.0, 0.0))}

ax = fig.gca(projection = '3d')
x = np.linspace(-5,5,no)
y = np.linspace(-5,5,no)
x,y = np.meshgrid(x,y)
R = np.sqrt(x**2 + y**2)
z = np.sin(R)
D = np.sqrt((x-5)**2 + (y-5)**2)
#and now I need to map distance D 
#making (-5,-5) blue and (5,5) red
