I'm not sure this sounds like something gnuplot would have built in as a 
capability. It sounds like you want an extrapolation of data beyond the 
range you are plotting. I would say you should compute some extra points 
beyond the ends of the line you're plotting using linear extrapolation. 
Then plots the set of 4 points and scale the axes so the two end points 
are off the edges of the graph.
