Re: spread color plot in opt@pltColorMap

Hi,

I think the problem is with these lines:

 undef("l2_norm_a")
 function l2_norma( x[*][*][*][*]:numeric, wy[*], wz )

and:

 undef("l2_norm_b")
 function l2_normb( x[*][*][*][*]:numeric, wy[*], wz )

On the "undef" line, it should read:

 undef("l2_norma")

and

 undef("l2_normb")

I think you are getting these errors because you are including this script twice:

load "NCARG_ROOT/lib/ncarg/nclscripts/csm/diagnostics_cam.ncl"
load "./diagnostics_cam.ncl"

Make sure you only load the modified copy. Meanwhile, I'll fix the undef errors on our end.
