[gradsusr] Background options failing

Wed Nov 9 16:14:43 EST 2011

Mason,
Okay, I put your script to work on a different computer system and got the
results you're looking for (I think, see attached image).  Here's the code
that got those results:

'open narr-a_221_19981218_0000_000.ctl'
hgt = 850
'set lev 'hgt
'set lat 34 46'
'set lon -114 -97'
'set mpdset hires'
'set display color white'
'clear'
tt = 1
while (tt <= 8)
 'set t 'tt
 'set cint 10'
 'set ccolor 0'
 'd HGTprs'
 'set clab %.0f`3.`1C'
 'set cint 2'
 'set cstyle 2'
 'set ccolor 2'
 'd (TMPprs - 273)'
 'set gxout barb'
 'd skip(UGRDprs,3,3);VGRDprs;mag(UGRDprs,VGRDprs)'
 'printim example_'tt'_'hgt'.png x800 y600'
 'clear'
 tt = tt + 1
endwhile

You'll notice the only things I changed (other than the path to the files)
is where I put some of the setup commands, and that I removed the "set
background" command.  You don't need to use both "set background" and "set
display" to get what you want.  In fact, I think those two commands sort of
canceled each other out.  I would suggest always going with the "set
display color white" ; "clear" sequence.  Changing either the background or
display color messes with the color that represents the "foreground" and
"background".  When you did "set background 1", you told Grads to set the
color index 1 to black and 0 to white instead of the other way around,
which is the default behavior.  I don't know if it matters to get much
deeper than that, but just use the suggestion I provided and you'll be fine.
