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.

• Load CSV files.
• Load ULog (PX4).
• Subscribe to many different streaming sources: MQTT, WebSockets, ZeroMQ, UDP, etc.
• Understand 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...

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, which 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 ;)

To learn how to use PlotJuggler, check the tutorials here:

Tutorial 1	Tutorial 2	Tutorial 3

Some plugins can be found in a different repository. The individual README files should include all the information needed to compile and use the plugin.

Please submit specific issues, Pull Requests and questions on the related Github repository:

• MQTT DataStreamer.
• Lab Streaming Layer DataStreamer.
• ROS plugins.
• CAN .dbg DataLoader.

If you want a simple example to learn how to write your own plugins, have a look at PlotJuggler/plotjuggler-sample-plugins

The snap contains a version of PlotJuggler that can work with either ROS1 or ROS2.

To install it in Ubuntu 22.04, with ROS2 support, run:

sudo snap install plotjuggler

If you are still using ROS1 (Ubuntu 20.04), install instead:

sudo snap install plotjuggler-ros

This installer does not include ROS plugins.

Windows Installer: PlotJuggler-Windows-3.9.0-installer

Install the ROS packages with:

sudo apt install ros-$ROS_DISTRO-plotjuggler-ros

To launch PlotJuggler on ROS, use the command:

rosrun plotjuggler plotjuggler

or, if are using ROS2:

ros2 run plotjuggler plotjuggler

ROS plugins are available in a separate repository: https://github.com/PlotJuggler/plotjuggler-ros-plugins

Please take a look at the instructions in that repository if you want to compile PJ and its ROS plugins from source.

You can find the detailed instructions here: COMPILE.md.

PlotJuggler required a lot of work to develop and maintain; my goal is to build the most intuitive and powerful tool to visualize data and timeseries.

If you need to extend any of the functionalities of PlotJuggler to cover a specific need or to parse your custom data formats, you can receive commercial support from the main author, Davide Faconti.
