Map Projections and Contour Plots. [message #15827]

I have data that corresponds to latitude and longitude.
example. data=40 , lat=20, lon=20

How would I...

...make the correct arrays expected by CONTOUR?
/IRREGULAR and TRIANGULATION work, but, I think they're causing
problems.

...smooth the contours?

The documentation says something about MIN_CURVE_SURF, but, it seems to
need the same format array as CONTOUR.

...plot the contours correctly over a map projection?

When I try to CONTOUR over a map projection, I get some lines across the

plot. The lines look like the contour tried to plot from, say, longitude

180 to -180.

So far, I'm only able to put a map ONTO a CONTOUR, not the other way
around. This doesn't help me when I want to use, say, /MOLLWEIDE.
