All-time figures cover only what we have observed since we began tracking this channel on . They are not the channel’s lifetime totals on Twitch.
Daily figures for the last 30 days. A day we never observed is drawn as a gap, never as a zero.
岸大河, last 30 days.
Total followers recorded each day over the last 30 days.
The axis starts at zero, so a week of growth on a large channel looks small — which is the honest reading.
The same numbers the charts draw, as a table.

Median for similar channels: 8.9
Median across measured channels: 1.97
Variation in the viewer count between readings, relative to what an audience of independent people would produce. Higher means more variation.
Chat figures come from sampling the public chat of 岸大河 for short windows; they count accounts that sent a message, not people watching silently, and most of any audience watches silently. What these numbers do and do not mean.

Times are UTC. Average and peak viewers come from periodic sampling of the live broadcast, so they are close estimates rather than exact platform figures. A stream marked “partial data” had gaps in our sampling; the unobserved time is excluded from its averages rather than filled in.
Rows marked “Archive” come from Twitch’s public VOD record. Date and duration are exact; viewership was not tracked at the time.
