[Gnuplot-info] acsplines question

[D. R. E. <doc...@gm...>]

I use the acsplines option quite a lot, but I now need a way to use the
plotted data as input to an external routine.

The command I currently use is of the form: "plot '<xxx>' using
($1):($2):(0.001) smooth acsplines notitle"

How would I do one of the following:

1. Output the data that are plotted by the above acsplines command (so that
they can be read by another program)?

2. Find documentation for the precise algorithm that the acsplines option uses?

Or, I suppose, any other way people can think of to obtain the plotted
acsplines data in a way that can be used by another program.
