Re: names of countries on map?

Erik,

I'm not sure if there's an automatic way to do this, which would be
cool, but when I've have to label certain cities in California I just
did it using "gsn_add_text", as in:

           plot = gsn_csm_contour_map_ce(wks,finarr,res)
           text = gsn_add_text(wks, plot, "SF", -122.43, 37.77, txres )
           text = gsn_add_text(wks, plot, "LA", -118.25, 34.05, txres )
           text = gsn_add_text(wks, plot, "SD", -117.15, 32.78, txres )
           draw(plot)
           frame(wks)

So, as long as you know the lat/lon of the area you want your text,
this should work for you, but certainly if there's an automatic way
that'd be more convenient for you.

ps, my "txres" just consisted of:

           txres = True
           txres_at_txFont = 22
           txres_at_txFontHeightF = 0.010
