Jay,
I put together a sounding set for testing a time series cross section
using wcmp, hght as the vertical coordinate as you have. This
worked for me (see attatched figure where red lines are SNPARM=sped,
and yellow are SNPARM=wcmp$90).
This was an unmerged sounding file (as dcuair would create).
Perhaps it would be useful for you to send me your data file,
or you could check that you are indeed looking at a new gif file
and not an old one (recall, GF will increment a counter
and add the number as an extension to the name so as not to
overwrite a previous file). Try using a new file name....and
verify that you are running gpend....checking the timestamp
on the resultant file.

Hi Steve,
Thanks for your help thusfar. I'm still having some problems, though...

I'm referring to the contour values not changing with the $xxx angle. The
wind barbs are plotting fine. I just tried running it with 5.6h a few times, and
had the same problem with wcmp equivalent to uwnd regardless of what angle I
used. Could it have something to do with me generating a time-height section for
one station instead of a cross section? Here's the nuts and bolts of it:
sncross<<EOF
CXSTNS = sac
SNPARM = wcmp$70
SNFILE = $soundfile1
DATTIM = 000212/0000-000212/1200
VCOORD = hght
PTYPE = lin
YAXIS = 0/8000/1000
TAXIS = R
LINE = 1//2
BORDER = 1//3
CINT = 3
WIND = bk1/1.2
TITLE = 1/-1/ Cross Frontal Wind - SAC
PANEL = 0
DEVICE = gf|../figures/sac_test.gif|.7;.8
CLEAR = no
FILTER = 1.0
TEXT = 1.3/23//hw
CURVE = 2
CLRBAR =
CONTUR = 7
FINT = 3/0
FLINE =
CTYPE =
run
Are there any other tricks that we might have to play? Thanks for your help!
