Attachment: [screenshot] one alert on a cloud of dots

I was trying to investigate a regression from 5 weeks ago and I could not see beyond that there was an alert.

Joel showed me that he can easily see alerts on a 14 day view:

https://treeherder.mozilla.org/perf.html#/graphs?series=mozilla-inbound,1644839,1,1

However, on my 90 day view I could not see that there was one alert:

https://treeherder.mozilla.org/perf.html#/graphs?timerange=5184000&series=mozilla-inbound,1643923,1,1&series=mozilla-central,1652331,0,1

Any ideas on how to improve this?

Hmm, it seems fairly clear to me that there's an alert on that image you sent -- the point is highlighted and there's a line through it. We could consider adding some widget/view to the graphs that let you list the visible alerts, I suppose.

To begin with, I was not even aware that alerts showed on PH graphs.

I did not notice that there's a dot that is different (until Joel mentioned it) or even that there's a vertical line (until you just mentioned it).

Closing as INCOMPLETE, as this is older than 18 months.
