[gradsusr] Plotting a gray-filled map and then overlaying variables

[Tracey]

Hi Bill,

Thanks so much for your reply.  I tried taking out 'c' but it still doesn't
display the gray map at the end of the script - the map still
disappears for some reason.  I should mention that I am running GrADS Version
2.0.2.

Thanks,
Tracey
