[edit] Summary

Description

Graph of logarithmic functions in SVG-format.

Red is log(x) base 2. Green is ln(x) (log(x) base e). Blue is log(x) base 10. Cyan is log(x) base 0.5.


I made this graph in gnuplot (post-processed using Inkscape), with these instructions:

set terminal svg
set output "logarithm.svg"
set title "Graph of logarithmic functions"
set xrange [0:10]
set yrange [-5:5]
set xtics 1,1,10
set ytics -5,1,5
set grid linewidth 3
set xzeroaxis linewidth 5
plot log10(x)/log10(2) notitle with lines linewidth 3, log(x) notitle with lines linewidth 3,
 log10(x) notitle with lines linewidth 3, log10(x)/log10(0.5) notitle with lines linewidth 3
show output
