[gradsusr] Filling entire plot area issue..

[Stephen McMillan]

William,
See if this gets you close enough:

'set lat 10 70'
'set lon -170 -50'
'set mpvals -120 -76 20 58'
'set mproj nps'

I know it's stereo polar, but I think it looks less distorted than if you
stick with the original projection you showed.  I assume you were using the
projection used by the NAM.  Good luck--

Stephen
