PlotJuggler: the log visualization tool loved by roboticists
UB2.147 | Day 1 | 18:30 - 18:55 | Speakers: Davide Faconti
Abstract
PlotJuggler is an open source QT/C++ application that allow developers to visuale and analyze timeseries from logs, that it is very popular in the robotics and drones community.
It supports both static files and real-time streaming.
Its plugin-based architecture makes it easy to extend; this allowed people to add more and more formats, in terms of streaming transport (Websocked, MQTT, ZeroMQ, UDP, ROS2, etc.), serialization protocols (DDS, Protobuf, JSON, Proprietary) and file formats (rosbags, PX4 logs, CSV, Arrow Parquet, etc).
Furthermore, it includes a Lua-based data editor that allows the user to manipulate and transform data, effectively replacing the need for those "short-lived" Python scripts that people in this community would create to quickly analyze their data.
Its Github repository (https://github.com/facontidavide/PlotJuggler) is approaching its 10th anniversary, with 5.5K stars, 2500+ commits and 120+ contributors.
