plot.js

plot.js is a small language for plotting and displaying math-type stuff in node.js

Example Usage

Plotting is easy! Just do:

var Plot = require("plot.js");

var p = new Plot();
var graph = p.render(input);

Where input is a set of mathematical statements in the plot.js language. For instance, to plot a quadratic function, input can be:

f(x) = x ^ 2
plot_x(f, -5, 5)

Full documentation for the graphing language has not been finished yet, however that document has begun to take shape here: Plot-language
