[ncl-talk] add text problem in Draw Order

[Erika Folova]

Hallo,

I have a question,, why the text that I added on top of my polygons hid
behind them..
can you suggest me why?

[SNIP]

ymin = new(3,float)
  ymax = new(3,float)
  do i=0,2
    getvalues plot(i)
      "trYMinF": ymin(i)
      "trYMaxF": ymax(i)
    end getvalues
  end do


  xmin = (/1990,2060/)
  xmax = (/2030,2099/)

  xbars = (/ (/xmin(0), xmax(0), xmax(0), xmin(0), xmin(0)/), \
             (/xmin(1), xmax(1), xmax(1), xmin(1), xmin(1)/)/)

  ybars = (/ (/ymin(0),ymin(0),ymax(0),ymax(0),ymin(0)/), \
             (/ymin(1),ymin(1),ymax(1),ymax(1),ymin(1)/), \
             (/ymin(2),ymin(2),ymax(2),ymax(2),ymin(2)/)/)


;;;;;; Create the bars and attach to appropriate plot
  gres             = True
  gres at gsFillColor = "gray95"

  do i=0,1
    do j=0,2
      poly((i*4)+j) =
gsn_add_polygon(wks,plot(j),xbars(i,:),ybars(j,:),gres)
    end do
  end do

; add text =========

*  txres                       = True*
*  txres at txPerimOn             = False*

~C~|tval|="+sprintf("%5.2f",abs(rc1 at tval))+" ("+sprintf("%5.2f",rc2 at tval)
+")",0.235,0.915,txres)*


; plot all
;===================

  attachres1                     = True
  attachres1 at gsnAttachPlotsXAxis = True
  attachres1 at gsnAttachBorderOn   = False
  attachres2                     = True
  attachres2 at gsnAttachPlotsXAxis = True
  attachres2 at gsnAttachBorderOn   = False

  attachid1  = gsn_attach_plots(plot(0),plot(1:2),attachres1,attachres2)

  pres = False               ; No resources needed
  maximize_output(wks,pres)  ; Maximize plot on page
