Interface ZoneTime

One zone's time + share.

Carries pond's canonical bin edges (start / end) so the array feeds @pond-ts/charts (<BarChart bins> / stacksFromBins) with no mapping step — the same { start, end, …aggregates } shape core's byColumn returns, and the same guarantee core enforces: finite, with end > start. (An infinite edge blows up a chart's axis domain; a zero-width bin is what byColumn itself rejects as unrepresentable.)

end

end: number

Upper edge — always finite, always > start. On a closed band this is the real edge. The open-ended band has none, so end is a drawable stand-in, never Infinity: wide enough to cover the highest value observed, and at least as wide as the band below. Treat it as a drawing bound, not as data — it can exceed anything actually recorded (and a device's out-of-range sentinel sample will stretch it).

fraction

fraction: number

Share of total in-zone time, [0, 1].

label

label: string

openEnded

openEnded: boolean

true on the open-ended top band, whose real upper edge is unbounded — end is a drawable stand-in. Label it "{start}+" rather than as a range.

seconds

seconds: number

start

start: number

Lower edge, in the value axis (watts / bpm / m·s⁻¹). Bands are inclusive-upper ((start, end]), so this edge belongs to the band below — except on Z1, whose floor is inclusive.

zone

zone: number

1-based zone number (Z1 = the lowest band).
