The x- and y-axis in my plot have the same size (set xrange [0,10], set yrange [0,10]). but When I plot it, Gnuplot shows it in a rectangle box. the x-axis stretches, although it has the same range. (If you plot a function like f(x)=x in gnuplot, you will understand me.)
What should I do to have it in a square shape?
This is a sample of my code to make eps from gnuplot:
set terminal postscript eps color enhanced "Times Roman" 30
set output 'pic22.eps'
set encoding iso_8859_1
set size 1.0,1.0
set border 31 lt -1 lw 2.0
set pointsize 1.5
set ytics 0.5
set xtics 0.5
set mytics 2
set xrange [0:1]
set yrange [0:1]
set xlabel "~{/Symbol a}"
set ylabel "~{/Symbol b}"
set lmargin -1
set bmargin -1
set rmargin -1
set tmargin -1
set key box opaque
set label "HD" at 0.6,0.3 textcolor "black" font "Times Roman,30"
set label "LD" at 0.3,0.6 textcolor "black" font "Times Roman,30"
set label "MC" at 0.6,0.6 textcolor "black" font "Times Roman,30"
set arrow from 0.5,0.5 to 0.5,1.0 nohead lw 2
set key off
f(x)=x
g(x)=0.5
pl (x>-1 && x<0.507 ? f(x):1/0) w l lw 3 lc 7 lt 1, (x>0.5 && x<1.1 ? g(x):1/0) w l lw 3 lc 7 lt 1
