Re: pattern line color

Thanks Adam.

This is how i did it, may be helpful to other NCLers

;*******************************
  res2 = True
  res2@gsnDraw = False ; don't draw yet
  res2@gsnFrame = False ; don't advance fra
  res2@gsnMaximize = True

   res2@cnInfoLabelOn = False ; turn off info label
   res2@cnLinesOn = False ; do not draw contour lines
   res2@cnFillOn = True
   res2@cnLineLabelsOn = False ; do not draw contour labels
   res2@gsnAddCyclic = True

   res2@lbLabelBarOn = False
   res2@cnMonoFillColor = False ; default color is fground
[black]
   res2@cnMonoFillPattern = False ; want multiple patterns
   res2@cnMonoFillScale = False ; want patterns w/ diff
densities

   res2@cnLevelSelectionMode = "ManualLevels"
   res2@cnMinLevelValF = 0.0
   res2@cnMaxLevelValF = 3.0
   res2@cnLevelSpacingF = 0.5

  ;***Here i want to put pattern for all values greater than 2.0 hence i am
using -1 for all values less than 2.0

   res2@cnFillPatterns = (/ -1, -1, -1, -1, -1, 6, 6, 6/) ;
-1=trasparent

;(/less than 0, less than 0.5, less than 1., less than 1.5, less than 2.0,
less than 2.5, less than 3.0, gretaer than 3.0/)
   res2@cnFillScales = (/1., 1., 1., 1., 1., 0.5, 0.5, 0.5/) ; add
extra density
   res2@cnFillColors = (/"white", "white", "white", "white", "white",
"azure2", "azure2", "azure2"/)

plots3 = gsn_csm_contour(wks, var1_ct, res2)

overlay(plots, plots3)
