Is this data from the same person?
If yes, probably some kind of error is going on, idk what though.
If no, the upper person has sleep apnea.
EDIT: Ok on second look these are two different graphs, presumably of the same night… with the upper one likely tracking heart rate and movement to guess at sleep stage, and the bottom just… location in bed vs some level of deep sleep?
Yeah I don’t know, either its configured wrong, its not sensing correctly, or you have sleep apnea.
Ok, if its the same person with sleep apnea and two different days, then what you’re looking at is two different data views or visualizations.
The top graph is more detailed, showing many different sleep states in detail, while the bottom is a more general, summarized view of just ‘in bed’ vs ‘good quality sleep’.
Probably the bottom graph is showing a more dull green for just being in bed vs the brighter green showing either just deep sleep, or core sleep plus deep sleep.
Somehow an option has been changed so that now you’re getting the simplified/summarized view.
