Humm. This seems right. You don't have some kind of
axis autoscaling going on, do you? You have set your
axes to exact scaling? And you have set the X and Y
scales for your data plot? And you have positioned your
map and plot into the same place in the window with the
POSITION keyword, right? If you have done all that, I think
it should work.

I've never used POLAR_CONTOUR. If it were me, I would have
probably converted my polar radar data into map coordinates
and just laid it on the map directly. I think that is what
I've done in the past when I was displaying NexRad radar data.
I'd have to check.

Cheers,

David
