Comment (by karsten):

 Okay, I now understand better what this ticket is about. Ignore my remark
 above, #29330 is unrelated.

 So, there are two things to consider here:

  1. The graph on Tor Metrics has a data granularity of 24 hours whereas
 yours has 3 hours. The clear cut in your graph is much less clear when
 looking at 24 hour averages. Unfortunately, there's not much we can do
 about this with our current graphing engine. Using daily averages is an
 easy way to reduce the overall amount of data, and for most use cases it's
 sufficient. There will always be edge cases when more detail is better,
 but I'm afraid that we can't address those cases with our current
 resources.

  2. It's certainly possible to provide a different view on the data by
 plotting four lines rather than four stacked areas. I'm aware that stacked
 area plots are not perfect. But they have advantages, too, including
 showing the overall bandwidth and how each class of relays contributes to
 that. What we could do, however, is make this configurable by offering
 stacked area vs. line plot. That could be part of #29340. Still, I don't
 know if the drop you refer to would be more visible in a plot with four
 lines and a data granularity of 24 hours.

 Does this make sense? Sorry, I'm afraid there's not much we can do here.
