Re: plotting points

Really, most of the following was constructed by looking
at assorted examples on the Application page.

load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl"
begin
;************************************************
; open file and read in data
;************************************************
   data = asciiread("loc",-1,"float")
   lat = data(...)
   lon = data(...)
;************************************************
; create plot
;************************************************
   wks = gsn_open_wks("ps" ,"jwsmith") ; open a ps file

   res = True ; plot mods desired
   res_at_gsnDraw = False ; do not advance the frame
   res_at_mpMinLatF = -20 ; range to zoom in on
   res_at_mpMaxLatF = 20.
   res_at_mpMinLonF = -20.
   res_at_mpMaxLonF = 20.
   plot = gsn_csm_map_ce(wks,res) ; draw global map

   polyres = True
   polyres_at_gsMarkerIndex = 16 ; polymarker
   polyres_at_gsMarkerSizeF = 5. ; polymarker size

   gsn_polymarker(wks,plot,lon,lat,polyres)
   frame(wks)
end
