We have invested a lot of time and effort in creating this project. Please consider citing or referencing LabPlot when using it in your work.

To cite LabPlot in publications use:

LabPlot Team (2023), LabPlot: A FREE, open source and cross-platform Data Visualization and Analysis software accessible to everyone, (Version 2.10.1) [Computer software]. https://labplot.kde.org.

What is the maximum limit of data set size?

LabPlot has no practical limits on data size other than the physical constraints of your computer.

Do you support the visualization of large data sets?

Yes, we put much effort to ensure that LabPlot is very fast at real-time viewing and plotting of large data sets.

Do you support live data?

Yes, LabPlot has been designed to read, visualize and analyze live data with the support for Unix/UDP/TCP sockets and a serial port.

Is it possible to use LabPlot in my own language, not English?

The interface is translated into multiple languages by KDE localization teams. If you want to help out, join the team for your language!

Is scripting possible?

Scripting, i.e. controlling LabPlot via APIs, is not possible at the moment but we plan to add this functionality in future. To automate workflows and computations in LabPlot, the notebook interface with the preferred underlying computer algebra system or programming languages has to be used.

Can I use multiple different Python installations with Computational Notebooks?

It is not possible to work with multiple different Python installations and switch between them at runtime yet. LabPlot's notebook interface to Python will only work with the version of Python that was used during the build step of LabPlot. We plan to get rid of this limitation in future.

Which verison of Python do I need to install to work with in in LabPlot?

See the previous question. On Linux distributions it usually means LabPlot only works with the system version of Python. For Windows, the installer provided by us was created with Python 3.10 and you'll need to install this version of Python on your computer and to add python's executable to PATH. For macOS the notebook interface is not available yet.

What is the license of the LabPlot website?
