If they are scattered values, you might use one of the
"gridding scattered data" functions, scat2gridgauss_xy
or scat2gridlaplace_xy.

There is a way to do this, which wasn't available in 1996.
Starting with Ferret version 4.9 or so, we are able to plot
fields using "curvilinear coordinates". One can do, for example,yes? SHADE clm[L=2], lat, lon
See the descriptions of this in the Users Guide, under "curvilinear
coordinates". There are curvilinear versions of the SHADE,
CONTOUR, FILL, and VECTOR commands.Ansley Manke

1:1How can I shade/contour/fill this in ferret like grid data?
Any suggestions would be appreciated.
Many thanks
