our_qt_plot

A plotting tool with GUI for rosbags converted into pandas dataframes

Pre-requisites

  • pyqt
  • pandas
  • matplotlib
  • numpy
  • psutil

Conda environment

conda create -n our_qt_plot_env python=2.7 pyqt pandas matplotlib numpy psutil
conda activate out_qt_plot_env

Note:

.pkl files created with different versions are not compatible. When using rosbag pkl files, they will typically be generated with a python 2.7 based pandas / pkl version and thus not be compatible with python 3 based pandas / pkl. The above conda environment should work with ros based files.

Using

Open the program using chosen config file. eg.

./our_qt_plot.py -c config/oqtplot_config_seabed.yaml

The click on load datafile and open the .pkl file.
