Re: Single color panel plots output

Hi Mary,

I am trying to do panel plot with 3 separate maps in the same window. You are right i am getting the same plot three times (no error message) but i have three different files to display (f2 correlation at 0 with three different f1 files). Still unable to figure out the problem. I appreciate your help. Thanks.
The script i am using is as below:

load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/shea_util.ncl"
        do i =5,7
         filename = "6104_pksec_"+sprinti("%0.2i",i)+".nc"
         print(filename)
         f1 = addfile(filename,"r")
        end do
        f1 = addfile("6104_pksec_05.nc","r")
        f2 = addfile("6104_pk_june_avg.nc","r")
        x1 = f1->a(lat|:,lon|:,time|:)
        print(min(x1))
        print(max(x1))
        x2 = f2->a
        print(min(x2))
        print(max(x2))
        x1!0="lat"
        x1!1="lon"
        x1&lat@units="degrees_north"
        x1&lon@units="degrees_east"
        c = escorc(x2,x1)
        copy_VarCoords(x1,c)
        print(min(c))
        print(max(c))
        printVarSummary(c)
  wks = gsn_open_wks ("x11","pksec_pk_06_panel") ; open ps file
  plot = new(3,graphic)
  gsn_define_colormap(wks,"Radar")
  res = True
  resP = True
  res@gsnDraw = False ; Don't draw plots
  res@gsnFrame = False ; Don't advance frames
  res@cnFillOn = True
  res@cnLinesOn = False
  res@mpOutlineBoundarySets = "AllBoundaries"
  res@mpDataBaseVersion = "MediumRes"
  res@mpDataSetName = "Earth..3"
  res@mpOutlineOn = True
  res@mpFillOn = False
  res@mpMaxLatF = 37
  res@mpMinLatF = 7
  res@mpMaxLonF = 125
  res@mpMinLonF = 60
  res@cnLevelSelectionMode = "ManualLevels" ; manually set cn levels
  res@cnMinLevelValF = -1. ; min level
  res@cnMaxLevelValF = 1. ; max level
  res@cnLevelSpacingF = .25 ; contour level spacing
  res@tiMainFontHeightF = 0.03
  res@gsnAddCyclic = False

  do i=0,2
  plot(i) = gsn_csm_contour_map_ce(wks,c,res)
  end do
  pres = True ; Set panel resources
  pres@gsmMaximize = True ; Maximize plots in panel
  pres@gsnPanelLabelBar = True ; Turn on panel labelbal
  pres@pmLabelBarWidthF = 0.8 ; Change labelbar width

  gsn_panel(wks,plot,(/3,1/),pres)

Subject: Re: Single color panel plots output

If you are getting an error message, please include the full error message in your email.

Are you asking about what to do with this code?

  do i=0,2
>>> plot(i) = gsn_csm_contour_map_ce(wks,c,res)
>>> end do

According to your print statements below "c" is two-dimensional, so
it doesn't make sense to loop three times and create the same plot
over and over.

Please give us more information about what you are trying to do.

Thanks,

--Mary

The only problem i have is to loop files at f1. Can you please look into it and suggest what is wrong. Thanks.
