What LabPlot is

LabPlot is free, open-source desktop software for visualizing and analyzing data. It creates interactive 2D plots, including scatter, line, histogram, box, bar, KDE, and control charts, and offers tools for statistics, linear and nonlinear regression, curve fitting, smoothing, interpolation, Fourier transforms, and signal processing. Interactive computational notebooks support Python, R, Julia, Maxima, Octave, and Lua.

LabPlot imports many formats and sources, including CSV, Origin, SAS, Stata, SPSS, MATLAB, SQL, JSON, Excel, HDF5, MQTT, FITS, netCDF, and ROOT. It can read live data from Unix, UDP, and TCP sockets, as well as serial ports. Its plot digitizer extracts data from images through manual point selection or semi-automated curve extraction. The software is available for Linux, macOS, and Windows, with packages also listed for FreeBSD and Haiku distributions. The project says LabPlot runs locally and does not collect, transmit, or store user data. It sits under the KDE umbrella and is supported by KDE e.V., a registered nonprofit in Germany. The project describes its audience as including engineers, students, and research scientists across scientific fields.
