Display multiple chromestatus timeline data buckets (e.g. addTrack which is shown as an example by default) in the same graph and combine them if you want.

• Note the bucket ids for the data you want to have graphed and add them as comma-separated list of buckets to the urls ?bucket parameter, e.g. ?buckets=2254 for addTrack which is the default. You can specify ?buckets=1641+2254+2513 to get a sum of the usage, this can be combined with drawing multiple buckets.
• use the ?window= parameter to control the window length of the rolling average. A window of 1 effectively disableѕ the rolling average, multiples of seven days work well since the data typically has a distinct workday/weekend pattern.
• use ?export to increase font size and plot width. Recommended for screenshots.
• use ?start=yyyy-mm-dd or ?stop=yyyy-mm-dd to look at a date range as alternative to zooming in.

Note (from chromestatus.com): on 2017-10-26 the underlying metrics were switched over to a newer collection system which is more accurate. This is also the reason for the abrupt spike around 2017-10-26.
