[tor-commits] [metrics-web/release] Remove Torperf/OnionPerf plots with all sources.

9 Nov 2019

commit c39472548511175a6eaa0d67de62d3b5fa59dbe3
Author: Karsten Loesing karsten.loesing@gmx.net
Date:   Wed Dec 5 11:56:19 2018 +0100
Remove Torperf/OnionPerf plots with all sources.
OnionPerf results look to be comparable over time, but between vantage
    points there are systematic deltas between the results. The "all"
    plots show rises and falls where they actually don't exist, it's just
    that a particular vantage point was offline so the average of the two
    remaining moves noticeably.
In this commit we remove the source parameter from these graphs and
    always include all sources separately in the graph, but not a
    combination of all measurements together.
Implements #28603.
