PlotJuggler 4 is an extensible, performant and open-source multi-modal visualization platform.
Explore recorded or live data, compare test runs, and analyze and transform your data, in a single application.
- Drag and drop your data. Drag signals into time-series and XY plots, zoom into events, and inspect individual samples.
- Validate changes across runs. Load several recordings, align their timelines, and overlay signals to compare behavior.
- Analyze the signal. Filter noise, measure rates of change, integrate values, or inspect frequency content with Fast Fourier Transforms.
- Add your own functions. Create derived series with custom transforms in Lua and Python, alongside the built-in filters.
- Reuse your analysis. Arrange plots in tabs and dockable panels, then save your layout and transforms for the next investigation.
Efficient data storage, GPU-accelerated rendering and on-demand media decoding help keep large recordings responsive as you explore.

Need a custom integration? Build a loader, streamer, parser or toolbox with the plugin SDK, or start from the official plugins.
Every build is attached to the latest release. Pick the one that fits your system.
Download PlotJuggler-<version>-Windows-x64.exe from the
latest release
and run it. It installs for the current user, so no administrator rights are
needed.
Recommended on Ubuntu 22.04+ and Debian 12+: add the apt repository once, and
future releases arrive with sudo apt upgrade.
curl -fsSL https://apt.plotjuggler.io/pj4_install.sh | sudo shPrefer to run the steps yourself?
The script (packaging/deb/pj4_install.sh) does exactly this:
sudo install -d -m 0755 /etc/apt/keyrings
sudo curl -fsSL https://apt.plotjuggler.io/plotjuggler-archive-keyring.asc \
-o /etc/apt/keyrings/plotjuggler.asc
echo "deb [arch=amd64 signed-by=/etc/apt/keyrings/plotjuggler.asc] https://apt.plotjuggler.io stable main" \
| sudo tee /etc/apt/sources.list.d/plotjuggler.list
sudo apt update && sudo apt install plotjuggler4To install a single release without adding the repository, download
plotjuggler4_<version>_amd64.deb from the
latest release
and run sudo apt install ./plotjuggler4_<version>_amd64.deb. A package
installed this way is not updated by apt upgrade.
Download PlotJuggler-<version>-x86_64.AppImage from the
latest release,
then make it executable and run it:
chmod +x PlotJuggler-*-x86_64.AppImage
./PlotJuggler-*-x86_64.AppImageIt needs glibc 2.35 or newer (Ubuntu 22.04 and later, or equivalent).
