You can still do it the previous way I mentioned, by reversing
your color map.
Or, you can download the latest gsn_code.ncl/gsn_csm.ncl (after
Tuesday July 24) and then swap the indices for gsnSpreadColorsStart
and gsnSpreadColorsEnd.
For example, if you want your filled contours to span from the last
color in the color table to the 5th color in the color map, you would
do the following:
gsnSpreadColors = True
gsnSpreadColorsStart = -1
gsnSpreadColorsEnd = 5
gsn_code.ncl and gsn_csm.ncl are available from:
http://www.cgd.ucar.edu/csm/support/CSM_Graphics/Scripts/gsn_code.ncl
http://www.cgd.ucar.edu/csm/support/CSM_Graphics/Scripts/gsn_csm.ncl
They will be updated on Wednesday, July 25th, or you can email me
privately and I will mail you the new scripts directly.
Cheers,
