[gradsusr] TEMPERATURE AND RH CONTOURS

sure you can have two shaded fields in one chart.  Obviously, unless one
is semi-transparent .. the 2nd will cover up the first.  That may be
fine if you only want to shaded some subset of the 2nd field.  For
example, I have one chart with "clouds" as greyshades, and precipitation
> 0.2mm overlaid (also shaded).  So if you only want RH > 50% shaded ..
then just mask out values < 50% and plot this second.

set your colour table
draw your first field
define your mask .. example ...   define mymask = (rh - 50%)
set your new colour table
draw your 2nd field .. example ... display maskout(rh, mymask)

easy peasy...

You can't display two shaded in one chart at the same time! one should
be shaded and the other one have to be in contour lines, respectively.

However,  'set gxout contour' will produce a contour line, and  'set
gxout shaded' will produce a shaded chart.

Good luck,
Mohsen
