Re: [Gnuplot-info] Plot all files in one only graph.

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

use one 'plot' command and add the individual plots without
line feed and leading comma:

#!/bin/bash

scriptfile="my_plot.gps"

# we want a fresh script file
rm -f $scriptfile

echo 'set terminal jpeg' >> $scriptfile
echo 'set output "all_plots.jpg"' >> $scriptfile

# one plot command only
echo -n 'plot' >> $scriptfile

# the first plot is undefined. thus we start the real
# plots with the second plot and can use a leading ","
# all the time.
echo -n ' 0/0' >> $scriptfile

# iterate over *.dat files
for i in *.dat
do
   echo -n ",'$i' u 1:2 w l title 'data from $i'" >> $scriptfile
done

#call gnuplot
gnuplot $scriptfile

# delete temporary file
rm $scriptfile
