Humm. Do you have some data?

I've been looking through examples of filled
polar contour plots for a few minutes. I'm not
sure which is the best way to approach this.
I have made some examples of this before (one
is on the back cover of my book!), but I made
that one with a map projection.

Anyway, if I had a good data set, I might
give it a try. :-)

Cheers,

David
