[gradsusr] Plot data text in a grid instead of random

Tue Dec 7 22:44:22 EST 2021

Running basemap.gs before means I have grid plots over the entire ocean as
seen here:

I prefer the look running basemap.gs after, I'm just trying to fix the
cutoff plots by the oceans, for example near San Francisco and southern
Louisiana as seen here:

Basically, I am trying to prevent the text cutoff without showing the
entire grid over the ocean.  Maybe it's not possible in GrADS.

As for the other issue, I'll just use set gxout contour without labels.

Thanks again!  I was able to use your maskout example nicely with precip
accum, btw!
