[ncl-talk] Help in Plotting

[Arun Kumar Dwivedi]

Hello Everyone,
I need to modify the interval on x and y axes according to my necessity but
I am not able to do that. I have attached the screenshot of my ncl window
and my is my code is as following:


load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"      ;Load the
required library files
load "$NCARG_ROOT/lib/ncarg/nclscripts/wrf/WRFUserARW.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_csm.ncl"
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl"

begin                                                         ;NCL script
always start with 'begin'

  a = addfile("wrfout_d01_2014-08-08_00.nc","r")              ;Loads the
required nc file

; Type of plot outputfile
;type = "x11"
; type = "pdf"
; type = "ps"
; type = "ncgm"
 type = "png"
;type at wkWidth = 600
;type at wkHeight = 800
  wks = gsn_open_wks(type,"final_gsn")                     ; Create op plot
file with name


;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
; First get the variables we will need
tk2 = wrf_user_getvar(a,"HGT",0)     ; T2 in Kelvin
tc2 = tk2-273.16                  ; T2 in C
lat = wrf_user_getvar(a,"XLAT",0)
lon = wrf_user_getvar(a,"XLONG",0)
;print(lat(:,0)) ;all lat values
;print(lon(0,:)) ;all lon values

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;Now everything will be drawn
draw(contour_tc)
frame(wks)

end


Kindly help me.
