LabPlot

LabPlot provides a free, open‑source environment for creating high‑quality visualizations and performing data analysis. Users can generate interactive plots with a few clicks, apply statistical tools, regression models, and curve or peak fitting, and work with real‑time data streams. The software includes a plot digitizer for extracting data from existing images and supports import and export across multiple file formats.

The application is built for cross‑platform use, running on Windows, macOS, Linux, FreeBSD and Haiku, and offers customizable theming to fit user preferences. It integrates with interactive notebooks, allowing scripts written in Python, R, or Julia to be executed directly within the interface, which streamlines computational workflows.

LabPlot is aimed at researchers, engineers, and analysts who need reliable, reproducible visual and analytical capabilities without proprietary restrictions. Its stable, mature codebase is maintained by a community of contributors and has received funding to continue development of core features.
