Re: color bar for anomaly

Hallo NCL,

Thanks Marry for the suggestion, I have another problem, how can i pick my
specific contour line color outside of my current color table. Let say, I
want to have a contour line color in "green"
using gsn_define_colormap(wks,"ncl_default") thus:
res@cnLineColor = "green". However, It doesn't work since in order to
use a named color, that color should be a part of my current color table.
Any suggestion? Thanks NCL.
