[Gnuplot-info] Plotting into datafile

[Hynek H. <ha...@br...>]

Hello,

please, is it possible to use gnuplot to plot into a datafile? I'd like
the 'plot' command not to draw graphics but give me back coordinates
of the data points as it would draw them, respecting the range and
using definitions.

I have a set of scripts which produce very nice gnuplot graphs
from my complicated set of raw data. Recalculate them, determine
the correct ranges etc. The problem for me is how to get back the
calculated data, not just the pictures :)

I'm looking for something like
    set term csv
    set output "graph_data.csv"
    plot [] [] .... using (2.126*($2), $175)... , ...., ...,

Which would give me a datafile, one column per one plot line.

Your help would be highly appreciated!
