symbol covered

Hi,

I want to use
 plot = gsn_csm_vector_scalar_map_ce(wks,u,v,uv,res)
  txres = True
  txres@txFontHeightF = 0.04
  txres@txFontColor = "blue"
  gsn_text(wks,plot,"+",-76.45,34.65,txres)

to make a "+", but it is covered by
gsn_csm_vector_scalar_map_ce(wks,u,v,uv,res)

How can I pull "+" out?
