lua-gnuplot is a small library for using gnuplot in a Lua program. It works by generating a [gnuplot][1] script from a Lua plot definition and calling the gnuplot program for you.
lua-gnuplot is licensed under the MIT license and can be freely used for academic and commercial purposes.
lua-gnuplot depends on gnuplot binaries.
lua-gnuplot is a pure Lua library. To install it, copy gnuplot.lua to into your Lua shared folder (eg, /usr/share/lua/5.2). You can also use the published Lua rock.
There is no documentation. Read the (rather compact) source code or see example.lua.
