Re: [Gnuplot-info] plot with table

[Patrick D. <pd...@gm...>]

Sorry, for the replot, I do not need the replot.

I want to do for example:

set table "out.asc"
plot  [44500:45600] (ampl*d_Lor_D (x-x0, W)+offset)
without getting the third column with "i"

or
plot $DATA u (x=$1):(ampl*d_Lor_D (x-x0, W)+offset)
for x taken from x_min to x_max with "samples" values

in other words.
I want in a file what I can plot with
replot ampl*d_Lor_D (x-x0, W)+offset
after a fit.

Thank.
