Re: scatter plot

You could turn your 3D array (ngroups x ny x nx) into a 2D array that is dimensioned ngroups x (nx*ny) by using ndtooned/onedtond, or "reshape" (if you have V6.1.0-beta):

   
  dims3d = dimsizes(my3darray)
  dims2d = (/dims3d(0),dims3d(1)*dims3d(2))

  my2darray = onedtond(ndtooned(my3darray),dims2d)

or, in V6.1.0-beta:

  my2darray = reshape(my3darray,dims2d)
