[gradsusr] problem: data Request is completely outside file limits

[Jeff Duda]

The valid time ranges of each file do not agree.  The first one is valid at
2007:2:14:13, which I presume is Feb 14 2007 at 1300 UTC (but I could be
wrong about that), while the second file is valid at 2007:2:14:19, which is
probably 6 hours later than the first file.  To plot them on the same set
of axes, you'll have to include a (time=  ) string to the second variable
in the display command.  By that, I mean,

'd spei.1 + spei.2(time=13Z14FEB2007)' (or whatever date it really is)

Hope this helps.
