LabPlot is a desktop application for visualising and analysing scientific and engineering data. With a few clicks you create interactive plots; it also offers statistics, regression, curve and peak fitting, extraction of data from plot images, and real-time data. Computational notebooks with Python, R, Julia and others are available as well. The program imports and exports many file formats and runs on Windows, macOS, Linux, FreeBSD and Haiku.
LabPlot is made by KDE, the community behind the Plasma desktop among other software, which is represented legally by KDE e.V., an association with its registered seat in Berlin. The software is open source under the GPL (version 2 or later). Because it runs locally on your own computer, your data and analyses stay with you and no account with the maker is needed. The project site mentions no hosted service. Development was co-funded through the EU's NGI Zero programme, run by NLnet.
