Thanks.  That almost works.  I get the plots I want, with the graph lines in
different colors, but the sample lines in the keys are all solid black, so the
keys don't help a lot.  Is there something else I should do?

On related topic, it would also be nice if there were some way to read in the
number of data sets from the input file, so I could write something like

plot for [i=0:n]

Is there any way to do that?  It appears I can just write

plot for [i=0:20]

where 20 is assumed larger than the number of data sets I'll ever have.  That
gets me some warnings, but otherwise seems to work.

Thanks for the response and for your time.
