Oh, probably. But FSC_SURFACE is trying to do something
clever (oh, I don't know why!) and may be having some
problems with "weird" data. Before I ruin the rest of
my day by asking for your data, try this:

fsc_surface, griddedData, xvector, yvector, $
position=[0,1,0,1,0,1]

Does anything show up now?

I hope not. But sometimes this method of gridding can
be a bit of a disappointment. Have you tried GridData
as an alternative?

Cheers,
