[gradsusr] Is there a way to restore the color to a constant field when plotting using gxout grfill?

Wed Jun 4 13:24:55 EDT 2014

Jennifer,

     Sorry for dropping the ball on this; the attached tar file contains 
the script, the input file, and the control file I'm using.

     I'm using GrADS v2.0.1.

     Please let me know if you need any additional info.  Thanks!

Cheers,
Bob
