## What it is
PlotJuggler is a fast, open-source desktop application for visualizing time series data with a drag-and-drop interface and OpenGL rendering. It loads files like CSV, ULog, and MCAP, subscribes to live streams (ROS, MQTT, WebSocket, ZeroMQ), and is extensible via plugins.

## Use cases
- plot time series from csv files
- visualize rosbag data
- debug robot sensor data in real time
- inspect px4 ulog flight logs
- stream and plot mqtt data live
- analyze imu and joint data at high frequency

## When to choose
- you need fast plotting of millions of data points
- you work with ROS or PX4 robotics logs and live topics
- you want reusable plot layouts and data transforms like derivatives and filters

## When to avoid
- you need statistical or scientific plotting with publication-quality figures
- you want a headless or purely programmatic plotting library
- you need business intelligence dashboards rather than time series debugging

## Facets
- artifact type: application
- maturity: active
- function: data-visualization, charts, parser, plugin-system, gui
- domain: data-visualization, robotics, analytics, developer-tools
- platform: windows, cpp, cross-platform
- tags: time-series, ros, rosbag, ulog, px4, mqtt, opengl, qt5, streaming-data, csv, linux, macos
