[gradsusr] unable to plot 2 files together

[Jeff Duda]

Your control files appear to contain data valid at different times.  You
need to adjust the time dimension.  Since you appear to want to display a
rain sum between two files valid at different times, you must use a time
string to change the valid time of one of the files.  In other words, you
will need to do something like

d rainnc.1+rainnc.2(time=03Z06JUN2011)

if you opened the files you listed above in chronological order.  The time
dimension in Grads is set by default to whatever the first time step in
control file #1 (the first control file you opened) is.  You can use 'set
dfile N', where N is the file number, to change this default behavior, but
you will still have to input a time string on all but one of the rainncs to
do a sum from files valid at different times.
