Read the metric definition
The week chart shows time tracked per day across the last seven local dates. Each bar comes from completed main-history sessions whose end falls on that date.
Inspect the contributing records
Read the day labels and the displayed hours, then open individual records if a bar surprises you. Compare the underlying start and end before interpreting the visual size.
The seven-day chart adds completed main-history durations by local end date. An overnight session is assigned as a whole to its ending day, and multiple records ending that day are added together.
Check the relevant distinction
An overnight session contributes its whole duration to the day it ended. It is not divided between the starting day's bar and the ending day's bar.

|---|---|
| Bar value | Sum of completed durations |
| Day assignment | Local end date |
Interpret within the data limits
The chart describes this ledger. It does not show meals, continuous physiological changes, or whether a routine is suitable for you, so keep questions matched to what was actually recorded.
Bar heights are scaled against the largest daily value in the current view, with a minimum scale. Read numeric labels for comparisons across different screenshots; visual height alone is not a stable unit.
A worked walkthrough
Consider an illustrative week with one overnight record and two shorter records ending on the same later day. The overnight duration appears entirely on its end date, while the two later records are added together for their shared date. A date with no completed main-history record has no counted duration, even if a session is currently running through it. If you archive one of the short entries, its contribution disappears from the corresponding bar. If that removal changes the largest daily value, other bars can look taller because the relative scale changed. None of those visual changes requires another session to have happened. To investigate, open the contributing records and verify their starts, ends, and placement. The chart is a convenient index into those records, and its meaning stays clearest when you keep the grouping and scaling rules in view.
