wp_live_plot

Live plotting of data on WatchPlant project.

Work in progress. This repository is a template for future package.

How to use the template

1. Put testing data in data folder.
2. Put definitions of ROS messages in msg folder. Remember to make necessary adjustments in CMakeLists.txt.
3. Put various scripts (things that are run occasionally, like preprocessing and testing) in scripts folder.
4. If using Python, put the source files in src/wp_live_plot.
5. If using C++, put the header files in include and source files in src.

Scripts

• csv2bag.py - Publishes data stored in CSV files as ROS messages which can then be recorded into a ROS bag. It is also useful to show data transformation equations.
  • rosbag record -a
  • rosbag play <name_of_the_file> -r 0.001 (When there is a lot of data, publishing messages at their true rate would take to long, so the script publishes at a higher rate (1 kHz). If you want to read the data at its true rate, you need to change the playback speed of the bag.)
