ncl Overview

The NCAR Command Language (NCL), a product of the Computational & Information Systems Laboratory at the National Center for Atmospheric Research (NCAR), is a free interpreted language designed specifically for scientific data processing and visualization. As of version 5.0.0, NCL and NCAR Graphics are released as one package in source code or binary format.
Support

Usage

Load the module to gain access to the NCL binaries and NCAR Graphics libraries. 
module load ncl
An example NCL file would look like this: 
load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"  
begin
  x = new(9,float)  
  y = new(9,float)
  x = (/10.,20.,30.,40.,50.,60.,70.,80.,90./)
  y = (/0.,0.71,1.,0.7,0.002,-0.71,-1.,-0.71,-0.003/)
  wks = gsn_open_wks("x11","gsun01n")  
  plot = gsn_xy(wks,x,y,False)         
end
Save this to a file and run: 
$ ncl gsun01n.ncl
This will open a graphical window with a plot of the x and y data in it. Make sure your SSH session has X forwarding enabled! 
$ ssh -Y titan.ccs.ornl.gov
