[gradsusr] Trying to plot values (grid? ascii?) of weasdsfc onto map.

[Stephen McMillan]

Yes, Chris, what you said makes sense.  If all you want to do is thin out
the number displays from a grid, then use "skip" (and maskout too if you
want to not plot the values over some area such as over water).  For
example:

'd skip(maskout(t2m,landsfc-0.5),2)'

displays every other grid value in both x- and y-direction over land areas
only, where "t2m" was my temperature variable.
