Re: warning:NhlDraw: cannot draw Plot Member, ID 68, independently

Hi Sabeerali,

This is a good error for us to add to our FAQ.

This error can happen if you try to draw a plot after it has been
overlaid on another one.

For example, if you have something like this:

   contour_line = gsn_csm_contour(wks,z1,res)
   ...
   res_at_cnFillOn = True
   contour_fill = gsn_csm_contour(wks,z2,res)

   overlay(contour_fill,contour_line)

   draw(contour_line)
   frame(wks)

you will get an error because once you overlay "contour_line"
on "contour_fill", you can't draw it individually.

The above two lines must be:

   draw(contour_fill)
   frame(wks)
