It's true, but at the expense of pretty much time, since the arcs must
be rendered properly. If your data is dense enough in r and phi, a
pcolor runs directly on polar plots just fine. No need to convert polar
to cartesian outside of matplotlib.

Hi,
After reading documentations and the matplotlib example I havent found a
way to graph the plot I want.
I am trying to display a radar video (one turn of the antenna at a time). As
such I need to plot a polar surface in 2D with a colormap indicating the
video intensity.
My data
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
