Dusty,
I'm assuming from your past questions that you are using sounding data.
The program SNCROSS can plot a time series at a single station,
of a spatial cross section at a single time.
For X axis representing time, and Y axis representing height,
you would set CXSTNS to the station id or WMO number
(eg CXSTNS=72365 or CXSTNS=ABQ). The Upper air file should
contain all the times for the station. If your data is in
separate daily files, then you would use SNMOD to copy
data to a single file.
The DATTIM parameter allows you to specify the time range to be plotted,
while the TAXIS parameter lets you configure the time axis.
For example, I have the ABQ soundings from July 11 to July 14 in the file
abq.gem ( I copied them from the daily files using SNMOD).
CXSTNS = abq
SNPARM = SKNT !<-- optional parameter to contour
SNFILE = abq.gem
DATTIM = 11/0000-14/1200
VCOORD = pres
PTYPE = log
YAXIS =
TAXIS = 11/0000-14/1200-12
LINE = 2
BORDER = 3;6;0/1/2;1
CINT = 5
WIND = bk5 !<-- plot wind spped in knots using
directional barbs
TITLE = 6
PANEL = 0
DEVICE = xw
CLEAR = y
FILTER = no
TEXT = 1/1/1/hw
CURVE =
CLRBAR =
CONTUR = 21
FINT = .01;2
FLINE =
CTYPE = c
