State Plotter

Uses Python and PyQtGraph to perform real-time plotting of ROS topics.

Usage

To use this package, you must add it to your working catkin_ws. This packages primary purpose is to expose the state_plotter Python package with the Plotter module.

In your own package, you create your own Python node that uses the state_plotter Python package. For example, consider the following directory tree:

catkin_ws
└── src
    ├── my_package
    │   ├── CMakeLists.txt
    │   ├── nodes
    │   │   └── state_plotter
    │   └── package.xml
    └── state_plotter
        ├── CMakeLists.txt
        ├── package.xml
        ├── README.md
        ├── setup.py
        ├── src
        │   └── state_plotter
        │       ├── __init__.py
        │       ├── Plotter.py
        │       ├── state_data.py
        │       ├── state_plot.py
        │       └── state_plotbox.py
        └── test
            └── basic_test.py
            └── advanced_test.py

In my_package, we have created a Python node called state_plotter. This Python node uses the state_plotter package to plot states:

Example

For an example of how to use the state_plotter, see the test/basic_test.py script. There is also a ROS node example given in nodes/mavros_plotter.py.

Documentation

See the wiki for documentation on the plotter functions and on using the argument classes to create plotbox and plot objects.
