-"""Generate graphs for data generated by full_stack_quality_sampler.cc.
+"""Generate graphs for data generated by loopback tests.
 
 Usage examples:
   Show end to end time for a single full stack test.
   ./full_stack_plot.py -df end_to_end -o 600 --frames 1000 vp9_data.txt
 
   Show simultaneously PSNR and encoded frame size for two different runs of
   full stack test. Averaged over a cycle of 200 frames. Used e.g. for
   screenshare slide test.
   ./full_stack_plot.py -c 200 -df psnr -drf encoded_frame_size \\
