Maureen,

I imported your data into a file, and plotted it in
sfgram with the following values:

SFFILE  = maureen.gem                                                           
  
DATTIM  = 21/09-22/09-0100                                                      
  
STATION = ME2K2                                                                 
  
TRACE1  = DWPF;TMPF/4;2                                                         
  
TRACE2  = PMSL/4                                                                
  
TRACE3  = ;BRBK/5                                                               
  
TRACE4  = RELH/7/0;100                                                          
  
TRACE5  = P01I/22/0;2                                                           
  
NTRACE  = 5                                                                     
  
TAXIS   = first-last-1;3;3;1

MARKER  = 0                                                                     
  
TITLE   = 4/1/ME2K2 PAST 24 HOUR METEOGRAM - 21/0900-22/0900 EST                
  
CLEAR   = YES                                                                   
  
DEVICE  = xw                                                                    
  
PANEL   = 0                                                                     
  
TEXT    = .90/21//sw                                                            
  

The dattim string above does filter the data at the top of the hour
in my plot (I'll attatch the gif).

I also ran with:
DATTIM  = 21/09-22/09
Without specifying a time step interval, I get all values.

At this point, I've tested the plot under Solaris and Irix and
don't seen to be able to duplicate your problem. I'll attatch the
gempak file I used above, and you can try with the above
sfgram values to see if things still don't work.

The only 2 things I see asstrange are your TIMSTN value
in the sfcfil invokation, and you had spaces between the
"-" characters in the dattim string in the email you
sent earlier. I created the surface file with TIMSTN = 200/2000
(you specified 300 times...200 is the max), but I can't see how
that would cause your problem.

Anyhow, try using the file I create with the values I have above
for sfgram. If you still see a problem, then we may need to see if your
sfgram program is somehow different. Otherwise, we probably need to
focus on the file creation.
