'''openPlaG''' is a [[PHP]] based function graph plotter for use on websites. It was first released in April 2006. In June 2007 its source code was published under the [[GNU GPL]] license. PlaG is an abbreviation for Plot a Graph.
The current version 3.2 of openPlaG allows the display of up to three [[Graph of a function|function graphs]], their [[derivative]] and their [[integral]]. It can compute several different functions, with a focus on a large function variety and on [[Probability distribution|probability functions]]. Settings for a graph can be saved and loaded. A substitution for a user-defined formula can be used. It has an instruction page, which explains the use of the plotter and the function syntax.
About 180 functions are predefined. These belong to the categories basic functions, [[Trigonometric function|trigonometric]] and [[hyperbolic function]]s, non-differentiable functions, probability functions, special functions, programmable functions, [[iteration]]s and [[fractal]]s, differential and integral equations.
