PlotJuggler 3.1

PlotJuggler is a tool to visualize time series that is fast, powerful and intuitive.

Noteworthy features:

  • Simple Drag & Drop user interface.
  • Load data from file.
  • Connect to live streaming of data.
  • Save the visualization layout and configurations to re-use them later.
  • Fast OpenGL visualization.
  • Can handle thousands of timeseries and millions of data points.
  • Transform your data using a simple editor: derivative, moving average, integral, etc…
  • PlotJuggler can be easily extended using plugins.


Data sources (file and streaming)

  • Load CSV files.
  • Load ULog (PX4).
  • Subscribe to many different streaming sources: MQTT, Websockets, ZeroMQ, UDP, etc.
  • Understands data formats such as JSON, CBOR, BSON, Message Pack, etc.
  • Well integrated with ROS: open rosbags and/or subscribe to ROS topics (both ROS1 and ROS2).
  • Supports the Lab Streaming Layer, that is used by many devices.
  • Easily add your custom data source and/or formats...

Transform and analyze your data

PlotJuggler makes it easy to visualize data but also to analyze it. You can manipulate your time series using a simple and extendable Transform Editor.

Alternatively, you may use the Custom Function Editor, that allows you to create Multi-input / Single-output functions using a scripting language based on Lua.

If you are not familiar with Lua, don't be afraid, you won't need more than 5 minutes to learn it ;)

Just "Download and Run"

On Linux, the simplest way to install PlotJuggler is through snaps:

Get it from the Snap Store

Windows Installer: PlotJuggler-3.1-WinInstaller.exe

How to build

Clone the repository as usual:

git clone --recurse-submodules

The only binary dependency that you need installed in your system is Qt5. On Ubuntu, the debians can be installed with the the command:

sudo apt -y install qtbase5-dev libqt5svg5-dev libqt5websockets5-dev libqt5opengl5-dev libqt5x11extras5-dev

On Fedora:

sudo dnf install qt5-qtbase-devel qt5-qtsvg-devel qt5-websockets-devel qt5-qtopendl-devel qt5-qtx11extras-devel

Then compile using cmake (qmake is NOT supported):

 mkdir build; cd build
 cmake ..
 sudo make install

Note: the plugins need to be installed in the same folder of the executable.

Note for ROS users

To install PlotJuggler, just type:

sudo apt install ros-${ROS_DISTRO}-plotjuggler-ros

I added a fix that will be available in the next release.

To launch PlotJuggler on ROS, use the command:

  rosrun plotjuggler plotjuggler

or, if are using ROS2:

   ros2 run plotjuggler plotjuggler

Since version 3.x, ROS plugins have been moved to a separate repository:

Refer to the instructions in the this repository if you want to compile PJ and its ROS plugins from source.

If you like PlotJuggler, support it.

PlotJuggler required a lot of work to be developed; my goal is to build the most intuitive and powerfull tool to visualize data and timeseries.

If you find PlotJuggler useful, consider making a donation on PayPal or become a Github Sponsor.

If you use PlotJuggler at work, your company can support the development of those specific features they need.
