[gradsusr] display one area with one word on map

[Chinh ta huu]

Dear all users

I 'd like to display one area in where includes some special values

For example:
I have geopotential height 500 mb (hgt500). There are a few points with
589mb and I'd like to display this area with *"H word"* on map.
If anyone know about that, could you comment me please

Thank you very much
Chinh
