Fityk is curve fitting and data analysis application, predominantly used to fit analytical,bell-shaped functions to experimental data. It is positioned to fill the gap between general plotting software and programs specific for one field, e.g. crystallography or XPS.[1]
Originally, Fityk was developed to analyse powder diffraction data. It is also used in other fields that require peak analysis and peak-fitting, like chromatography or various kinds of spectroscopy.[2]
Fityk is free and open source, distributed under the terms of GNU General Public License, with binaries/installers available free of charge on the project's website. It runs on Linux, macOS, Microsoft Windows, FreeBSD and other platforms. It operates either as a command line program or with a graphical user interface.
It is written in C++, using wxWidgets, and providing bindings for Python and other scripting languages.
The programs LabPlot, MagicPlot and peak-o-mat have similar scope.
More generic data analysis programs with spread-sheet capabilities include the proprietary Origin and its clones QtiPlot (paid, closed source) and SciDAVis (non-paid, open source).
