Basically, I have a list of data points in spherical coordinates which represent an antenna pattern. I'd like to plot them and have it look something like this:

My data is only taken every 15 degrees. So I can't do something like this person did:
http://ask.sagemath.org/question/512/plotting-in-3d-in-spherical-coordinates
The reason is that if I create a continuous interpolated function I'd be fabricating data (unless I can re-create a picture like the one above closely).
Ideally a spherical list plot would be ideal, but it seems like the current list plot is only cartesian.
After I successfully get my data plotted, the next steps for my antenna plot viewer would be
1) Make the color map scale set-able (so that multiple antenna plots have colors on the same scale, even if data ranges are different).
2) Make grid-lines visible, like on my picture above.
3) Apply a bicubic interpolation to my data mesh, so it would then look like this (for visual purposes): http://i.imgur.com/U4hPW.png
4) Make the xyz axes visible, like the pic.
All these seem pretty easy, except maybe #2, if anyone knows how that could be done it would be greatly appreciated.
Thanks so much everyone for working on this software. I look forward to this becoming a great tool for engineers and scientists. JasonMon, 07 Nov 2011 01:49:06 +0100https://ask.sagemath.org/question/8448/
