Re: Error in ploting correlation

Hi Rashed,

Just a further explanation on why you are seeing green land fill:
normally the land is supposed to be filled in with gray (a
gsn_csm_xxx_map default). You chose a color map that didn't have gray
in it, so NCL chose the next closest color in your color map, which
was light green in this case.

I'll add this to our FAQ, since it's a common problem that users run
into.
