Not exactly. The whole plot will be filled in because there's a diode
response for each elevation and azimuth pair. The diode response
doesn't change linearly so I can't use the vector idea. I want the
colors to match the data in highest to lowest value order (or vice
versa) but the data isn't written this way (it should end up looking
like a ring or ellipse pattern with greatest response/darkest color on
the outside and lowest response/lightest color on the inside). I have
a picture of something similar in Python but I can't attach it to a
post. Is there any way I can make a surface plot of the data, give it
elevation shading, and then just view it top down so I only see the x
and y axes and colored rings?
