[Gnuplot-info] plotting points using a line of best fit function

[Ben E. <bj...@ai...>]

Hi.

I have a line of best fit calculated using the "fit" command.  I'm
trying to work out how to map new x axis values onto this function and
plot these additional points.  If I do something like:

  plot f(3) with points

then I get a straight line at y=f(3).  Is there a way to plot (3,
f(3)) instead?

Thanks, Ben
