There's a huge problem with that idea.  There's no particular reason 
every dataset should have the same number of samples, much less the same 
x positions.  Please keep in mind that functions in gnuplot are, 
effectively, just internal datafile generators.

As soon as gnuplot actually gets for loops around commands: sure.  So 
far that hasn't been done, though.  What you get know are loop 
constructions _inside_ the plot command, which are an entirely different 
thing.

In the end, you're making the opposite of a very common mistake.  Many 
people out there abuse spreadsheets as plotting programs.  You appear to 
be trying to abuse gnuplot as a spreadsheet.
