[ncl-talk] Can NCL plot polygons?

[Rick Brownrigg]

Hi Barry,

Is this what you are looking for?

     http://ncl.ucar.edu/Document/Graphics/Interfaces/gsn_add_polygon.shtml

 It follows the standard

   res at gsnFrame = False
   res at gsnDraw = False
   ....

   draw(plot)
   frame(wks)

paradigm that you've perhaps seen before. Each invocation of
gsn_add_polygon() requires that you assign the return value to a unique
variable/array-element.

HTH...
Rick
