How to suppress the warning info "entire grid undefined" in GrADS

[Mary Jo Nath]

Haibin,

I don't know if there is a way to suppress the undefined message, but you
can get just the background if you open a real data file,  then use "set clevs"
to set a contour value that is  out of range of that data, and then display the variable.
