Hello, Mary
Thank you very much for your thorough response. I have given up on using
gsn_contour_shade and decided to just specify the exact colors using
cnFillColors.
On a labelbar that looks like the attached one (InteriorEdges), which does
the white color represent?
0 > white >= -0.2
or
0 >= white > -0.2 ?
Thank you again
Paula
