PlotJuggler 3.14

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 reuse 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.
• 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…

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, 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 ;)
