Re: Controlling x and y ranges for gsn_contour

Hi Sean,

If I understand you correctly, I think you need to set:

   res_at_sfXArray = x
   res_at_sfYArray = y

This tells NCL what values define your X and Y axes. Otherwise, it
will just use index values that go from 0 to n-1, where n is the
number of points in the Z array in the X or Y direction.

Here's a small example using your same X,Y values.

load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl"

begin
   wks = gsn_open_wks("x11","test")

   x = (/2,4,6,2,4,6/)
   y = (/5,5,5,7,7,7/)
   z = (/1,2,3,2,1,3/)

   res = True
   res_at_sfXArray = x
   res_at_sfYArray = y

   plot = gsn_contour(wks,z,res)
end
