Hi there -

My goal is to shade a contour plot with everything < 0 a light gray, but draw several more contours that are all in black. It seems I can't figure out how to do this. Any suggestions would be useful. I have:

plotres@cnFillOn = True
gsn_define_colormap(wks,(/"white","light gray"/))
plotres@gsnSpreadColors = True
plotres@gsnSpreadColorStart = 1
plotres@gsnSpreadColorEnd = 0
plotres@cnMonoLineColor = True
plotres@cnLineColor = "black"
plotres@cnLevelSelectionMode = "ManualLevels"
plotres@cnMinLevelValF = -10.
plotres@cnMaxLevelValF = 10.
plotres@cnLevelSpacingF = 0.1
plot(0)=gsn_contour(wks,profs_T,plotres)

I get the correct shading, but the contours and plot boundaries are also light gray.

Cheers,
Josh
