Hi!
I have been trying to draw an arrow on a map without success. I have set
mpFillDrawOrder = "PreDraw", but the map still seems to cover my arrow.
Could it have something to do with the projection perhaps?
Below is my ncl script. Help will be greatly appreciated.
Thanks
Andrea
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl"
begin
wks = gsn_open_wks("x11","arrow") ; open a workstation
res = True
res@gsnDraw = False
res@gsnFrame = False
res@mpProjection = "Stereographic"
res@mpCenterLonF = 23.
res@mpCenterLatF = 90.
res@mpLimitMode = "Corners"
res@mpLeftCornerLatF = 37.7823
res@mpLeftCornerLonF = 23.4808
res@mpRightCornerLatF = 38.2082
res@mpRightCornerLonF = 24.1032
res@mpFillOn = False
res@mpFillDrawOrder = "PreDraw"
plot = gsn_csm_map_ce(wks,res) ; draw map
wmsetp("ARD",90.)
wmsetp("ARS",0.1)
x = 38.0 ; lon
y = 23.8 ; lat
wmlabs(wks, x, y, "ARROW")
draw(plot)
frame(wks)
end
