Stephane,
First off, you probably do not want to use a surface plot. Rather, pcolor
might be more appropriate.
In addition, if you can take the azimuth-range coordinates and convert that
into x-y coordinates, you can then plot a pcolor using just that. The code
would look something like so (assuming some function polar2xy exists):
# azimuth, r, vals, x, and y are all the same shape
x, y = polar2xy(azimuth, r)
plt.pcolor(x, y, vals)
plt.show()
Once that is working sufficiently, then you will have to modify the code a
bit to specify the colormap.
I hope that gets you started.
