Some useful answers

Which files fit I open?

CSV files from sleep apps, wearables, spreadsheets, sleep diaries or focus timers go work if dem get date and number values. Choose comma, semicolon or tab separators. Use YYYY-MM-DD dates, ISO timestamps, or choose the order clearly for slash dates. Time length text like 7h 30m need turn to number first.

Wetin happen to missing or repeated days?

The viewer show all calendar dates between the first and last date wey you map. Missing values leave gaps. If one date get plenty values, dem go average each measure by itself. Weekly patterns use the daily averages wey dey available and show how many values dem use.

Chart mean say person get sickness?

No. Na observations wey dey describe wetin show. Dem no fit prove cause and effect or diagnose any condition. If sleep or health dey worry you, talk to qualified health professional.
