Source code

Created with gnuplot using the following input file:

set terminal svg font "Bitstream Vera Sans,18" size 600,400
set output "Logistic-curve.svg"

set xrange [-6:6]
set xzeroaxis linetype -1
set yzeroaxis linetype -1
set xtics axis nomirror
set ytics axis nomirror 0,0.5,1
set key off
set grid
set border 1

set samples 400

plot exp(x)/(1 + exp(x)) with line linetype rgbcolor "orange" linewidth 2

SVG output filtered with the following command to replace the hyphens with proper minus signs:

sed -i 's/<text>-/<text>\xE2\x88\x92/g' Logistic-curve.svg
