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.

Analyze signals interactively

• 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.

Multimodal data, synchronized in time

Efficient data storage, GPU-accelerated rendering and on-demand media decoding help keep large recordings responsive as you explore.

Work with the data you already have

Open supported formats directly and connect to your existing sensor and messaging systems. Install ready-to-use loaders, streamers and tools through File → Marketplace:

Need a custom integration? Build a loader, streamer, parser or toolbox with the plugin SDK, or start from the official plugins.

How to get started

Every build is attached to the latest release. Pick the one that fits your system.

Windows

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.

Debian and Ubuntu (apt repository)

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 sh

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 plotjuggler4

To 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.

Any Linux distribution (AppImage)

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.AppImage

It needs glibc 2.35 or newer (Ubuntu 22.04 and later, or equivalent).
