Gnuplot source code
set terminal svg fname "Helvetica" fsize 25
set output "LinearRegression.svg"
set key left
set xtics axis 1,1
set ytics nomirror 1
set border 2
f(x) = a*x + b
fit f(x) 'randpts' using 1:2 via a,b
set yrange [-0.9:4]
plot 'randpts' with points pointtype 7 pointsize 0.3 title 'Datapoints', \
f(x) with lines linetype 3 linewidth 3 title 'Regression', \
0 with lines linetype -1 notitle
The datafile 'randpts' was made in GNU Octave using the commands
f = fopen('randpts', 'w')
for i=1:200;
x=rand(1);
y=0.7*rand(1) + 3*x;
fprintf(f, '%g %g\n', x, y);
end
fclose(f)
(identical code also works in Matlab.)
