[ncl-talk] gsn_contour_shade

Adam and Rick:

I had tried Adam's suggestion earlier

ores at cnMonoLineThickness = True

ores at cnLineThicknessF    = 3.0

but that did not work. Rick's suggestion did not work either:

ores at gsnContourLineThicknessesScale = 2.0


May be we just can't do this with gsn_csm_shade after all. I also tried to
include them in the opt option used in the call to gsn_csm_shade, but that
did not work either.


Many thanks,
Laura
