Re: [Gnuplot-info] How to plot and save many data files in GNUPLOT, inside a loop in a SHELL SCRIPT

[Thomas S. <t.s...@fz...>]

have a look at the 'reread' command. an example:

################################
i = 1
n = 1000
set terminal jpeg
load "loop.plt"
################################

"loop.plt" contains:

################################
filename = "output".i.".txt"
plotfile = "graph".i.".jpg"
print filename." ".plotfile

set output plotfile
plot filename using 1:2, "" using 1:3
set output

i=i+1

if (i <= n) reread
################################
