Re: Contours overlay problem

Soumik

You should be able to colour your contour lines by setting

sres@cnMonoLineColors = False

getvalues plot@contour ;retrieve contour plot colormap
  "cnFiLLColors" : cols
end getvalues

sres@cnLineColors = cols ;set line colors

The 'getvalues' statement is outlined in a previous post:
http://www.ncl.ucar.edu/Support/talk_archives/2012/0731.html

Obviously, you will have to have already plotted a filled contour base
plot(named 'plot' in my example) or there won't be a colormap to retrieve.
You can then draw the contour lines on a separate plot, and use overlay()
to add it to the base plot.
