Re: [Gnuplot-info] extrapolation beyond input range?

[Dan J. <ji...@ji...>]

Saw http://groups.google.com/groups?th=51915a0bd68a63ca .  OK, I guess
I wanted a way to get gnuplot to 'keep drawing those great lines,
don't chicken out when you come to the edge', but at the same time
"don't ask me to derive some function to fit my data, just use the
points I gave you".

So I suppose what I want (to see implemented and documented in
gnuplot, though I don't really need to use it today) is a way to make
gnuplot "keep on drawing those straight lines when you come to the
edge, if you were drawing straight lines", "keep on drawing curves if
you were drawing curves".  And "you were plotting nicely with that data
file I gave you, don't ask me to wrack my brains to write a function,
I won't blame you if it's just a guess where to extend those lines,
just keep on...(until the new edge I specify beyond the data points.)"

I mean can't gnuplot make some best fit parabola or something for the
given points? Well, "tell it not to chicken out but just keep going to
infinity".
