Graphest

Graphest is a graphing calculator that can faithfully plot arbitrary mathematical relations.

Getting Started

Download the app (available for both macOS and Windows), and try plotting some of the example relations.

Plot arbitrary equations/inequalities
Never gives an incorrect result; if you find any relation plotted incorrectly, please report it here
Cartesian and polar coordinates
Parametric relations
Full interactivity
Extensive set of mathematical functions

Graphest aims to provide a modern, open-source and extensible alternative to GrafEq™ [Ped].

The following algorithms in [Tup01] are implemented: 1.1–3.2, 3.3 (partially), 3.4.1–3.4.3, 3.4.5 (partially).
