I've been following this thread with some interest. One problem that I
might have with the code above is that as it is, the plot is labeled
with 0-deg to the left, and numbered counter clockwise (standard
trigonometric format). Most field mapping data I have collected has been
either in quadrant form (rarely) or more commonly in azimuthal form
(0-360 degrees order clockwise from the top). Is that an issue?
