Re: Vector

I just want to put country boundaries on a vector plot, but the
resource mpOutlineBoundarySets = "National" or "allBoundaries" didn' t
show any line.
And with gsn_csm_vector_scalar_map_ce, all the continenta are colored
gray, without any line. How can I plot the data over the continent?

That is my code:

load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/shea_util.ncl"
;************************************************
begin
;************************************************
; read in netCDF file
;************************************************
  a = addfile("DT53P008-FMA.nc","r")
;************************************************
; read in zonal [u] and meridional [v] winds (July)
;************************************************
  u = a->U(0,:, :,:)
  v = a->V(0,:, :,:)
;************************************************
; create plot
;************************************************
  wks = gsn_open_wks("pdf","vector-FMA") ; open a ps file
  plot = new(18,graphic)

  vcres = True ; plot mods desired
  vcres@gsnDraw = False ; Do not draw plot
  vcres@gsnFrame = False ; Do not advance frome

  vcres@vcRefAnnoOrthogonalPosF = -1.0 ; move ref vector up
  vcres@vcRefMagnitudeF = 10.0 ; define vector ref mag
  vcres@vcRefLengthF = 0.045 ; define length of vec ref
  vcres@vcGlyphStyle = "CurlyVector" ; turn on curly vectors
  vcres@vcMinDistanceF = 0.017

  vcres@mpOutlineBoundarySets = "allBoundaries"

  vcres@pmTickMarkDisplayMode = "Always" ; turn on tickmarks

  vcres@mpMaxLatF = 9
  vcres@mpMinLatF = -23
  vcres@mpMaxLonF = -30
  vcres@mpMinLonF = -85

do n=0, 17

  plot(n) = gsn_csm_vector_map_ce(wks,u(n, :,:),v(n, :,:), vcres)

end do

 gsn_panel(wks,plot,(/6,3/),False)

end

Thanks,
