set mpt

command to control map background behavior. type is the map type; it can be a number from 0 to 255, or it can be an asterick(*) to indicate this command applies to all the type values. The color can be set to -1, which indicates to GrADS to use the set map settings for this map type, rather than the settings specified by the set mpt command.

Usage Notes

Examples

1. Lets say you want to use the hires data set and plot political boundaries, but not state boundaries:
   set mpt * off
set mpt 0 -1
set mpt 1 -1

2. Lets say you want to use the hires data set, and have coastlines be thicker, and a different color, than political boundaries:
   set mpt * off
set mpt 0 1 1 6
set mpt 1 15 1 1

3. The set mpdraw and draw map commands work as before; you can do some interesting line types by overlaying:
   set mpt 51 7 1 12
draw map
set mpt 51 0 1 1
draw map

   This would produce two yellow lines parallel and close together for map type 51.
