DrawOrder

Hallo NCL,

Sorry fow a simple question. I just wonder why the draworder did not solve
my problem to put the polygon behind the bar chart. Here is my resources
settings:

 wks = gsn_open_wks ("pdf", "bar" )
  res = True
 res@gsnScale = True
 plot = new(2,graphic)

 res@gsnDraw = False ; don't draw
 res@gsnFrame = False

 res@vpXF = 0.14 ; In page coordinates, where to start
 res@vpYF = 0.75 ; the plot
 res@vpHeightF = 0.43 ; Changes the aspect ratio
 res@vpWidthF = 0.85

 res@trYMinF = -3.0 ; min value on y-axis
 res@trYMaxF = 3.0 ; max value on y-axis

 res@tiYAxisString = "Time" ; y-axis label
 res@tiMainString = " " ; title
 res@gsnLeftString = "DJF"

 res@gsnYRefLine = 0. ; reference line
 res@gsnXYBarChart = False ; create bar chart
 res@gsnAboveYRefLineColor = "red" ; above ref line fill red
 res@gsnBelowYRefLineColor = "blue" ; below ref line fill blue

;===============================================================================

 nk = 32
 time = ispan(1980,2011,1)

  xp = new( (/2*nk/), float )
  yp = new( (/2*nk/), float )

  do i=0,nk-1
   yp(i) = 3*climJFM(0)
   xp(i) = time(i)
   xp(2*nk-1-i) = time(i)
   yp(2*nk-1-i) = -3*climJFM(0)
 end do

nk1 = 32
 time1 = ispan(1980,2011,1)

  xp1 = new( (/2*nk1/), float )
  yp1 = new( (/2*nk1/), float )

  do i=0,nk1-1
   yp1(i) = 1*climJFM(1)
   xp1(i) = time(i)
   xp1(2*nk1-1-i) = time(i)
   yp1(2*nk1-1-i) = -1*climJFM(1)
 end do

;===============================================================================

 plot(0) = gsn_csm_xy (wks,ispan(1980,2011,1),JFM(0,:),res)

 res@gsnLeftString = "MAM"
 delete(res@tiMainString)

 gsres = True ; poly res
 gsres@tfPolyDrawOrder = "Draw" ; draw this first
 gsres@gsFillColor = "SlateGray"
 dummy = gsn_add_polygon (wks,plot(0),xp,yp,gsres)

 plot(1) = gsn_csm_xy (wks,ispan(1980,2011,1),JFM(1,:),res)

 gsres1 = True ; poly res
 gsres1@tfPolyDrawOrder = "Draw" ; draw this first
 gsres1@gsFillColor = "SlateGray"
 dummy1 = gsn_add_polygon (wks,plot(1),xp1,yp1,gsres1)

 gsn_panel(wks,plot,(/2,1/),False)
  end

thank you,
