Re: symbol covered

Yongzuo,

The "+" should appear on top if you are calling it after gsn_csm_vector_scalar_map. You didn't include your full code or a sample image, so I'm not sure how you are calling things.

Also, instead of gsn_text, you can try gsn_add_text. This attaches the text string to the plot, and then you need to draw the plot in order to see the text string:

   . . .
   res@gsnDraw = False
   res@gsnFrame = False
   . . .
   plot = gsn_csm_vector_scalar_map_ce(wks,u,v,uv,res)
   txres = True
   txres@txFontHeightF = 0.04
   txres@txFontColor = "blue"
   txid = gsn_add_text(wks,plot,"+",-76.45,34.65,txres)

   draw(plot)
   frame(wks)
