[ncl-talk] Plotting polygons on xy plot [SEC=UNCLASSIFIED]

[Griffith Young]

Another way to do this that doesn't involve creating a "dum2" variable is to use "unique_string" to create a unique name, and then use this unique name as an attribute to any variable that holds the return value from gsn_add_polygon. I usually use the "plot" variable:

 plot@$unique_string("polygon")$ = gsn_add_polygon(wks,plot_without_ygrid,xbar,ybar,bres)


Hopefully by fixing this, your other issues with colors will resolve themselves.

Hello Mary,
                Thank you for this very creative solution.  I can see where this could be used in so many other places.

                Very much appreciated!

Regards,
                Griff.
