Creating Square Plots with Gnuplot

#############################

Description

Here I sum up how I usually use gnuplot.

Details

First, I write an "include" file where I collect the common parts:

common.inc.gp:

set terminal postscript enhanced "Helvetica" 20
#
set style line 1 lt 1 pt 6 lw 3
set style line 2 lt 2 pt 2
#set style line 3 lt 1 pt 8
#set style line 4 lt 1 lw 3
set key left top
set key spacing 1.5
#
set xlabel "minimum support (%)"
set ylabel "total time (sec.)"
set output "plot.eps"
#
set size square

Then comes the specialization:

script.gp:

load "common.inc.gp"
#
set title "Title"
set logscale y
set ytics ("0.1" 0.1, "1" 1, "10" 10, "100" 100, "1000" 1000)
plot [80:50][:1000] \
   "data.dat" using 1:2 title "Algorithm 1" with linespoints linestyle 1, \
   "data.dat" using 1:3 title "Algorithm 1" with linespoints linestyle 2

At the end, you can compile it with the command gnuplot script.gp .
