QtiPlot is a cross-platform computer program for interactive scientific graphing and data analysis. It is similar to the proprietary programs Origin or SigmaPlot.

QtiPlot can be used to present 2D and 3D data and has various data analysis functions like curve fitting. Plotting of 3D data can be rendered using OpenGL using the Qwt3D libraries.

The program is also extensible to a considerable degree via muParser and Python scripting language, which allows adding the arbitrary user-defined functions with access to graphs, matrices and data tables.

Older QtiPlot versions up to were released under the terms of the GNU General Public License (GPL) and are available also as binaries for Linux distribution repositories[1] as well as for Windows.[2]

Starting with version 0.9.9 the source code is not available from the author anymore. Compiled binaries are available for Microsoft Windows, several Linux distributions and Mac OS X; downloading binaries from the author's website requires purchase of an annual maintenance contract. Files saved by version 0.9.9 cannot be loaded by version 0.9.8.
