Bruce,
Hopefully the email I sent yesterday answers your questions about non
geographical uses for gsn_csm_contour.
For 2D coordinates, you can use sfXArray, sfYArray:
res_at_sfXArray = x
res_at_sfYArray = y
Really, when you do "data_at_lat2d" and "data_at_lon2d", it's just creating
the above two lines for you, so
it's the same thing.
