A script for producing boxplots by parsing data generated by the apm_quality_assessment.py tool. The script groups data by the values of one or several audioproc_f parameters. For every such subgroup it draws a boxplot. All boxplots are shown next to each other with the parameter value as the x axis. It is similar to this matplotlib example: https://matplotlib.org/mpl_examples/pylab_examples/boxplot_demo_06.png The script 1. reads config file names from the pandas dataframe generated by quality_assurance.collect_data 2. parses the (JSON) config files to read the parameter values 3. groups data with matching param values together 4. draws a boxplot for each group using matplotlib TBR=alessiob@webrtc.org # reviewed already in old gerrit https://chromium-review.googlesource.com/c/external/webrtc/+/660559 BUG: webrtc:7218 Change-Id: I380a1363d26721feb975fad1506835c622e9d926 Reviewed-on: https://webrtc-review.googlesource.com/6340 Reviewed-by: Alex Loiko <aleloi@webrtc.org> Commit-Queue: Alex Loiko <aleloi@webrtc.org> Cr-Commit-Position: refs/heads/master@{#20139}
