I'd like the x-axis to show dates
I'd like each date/bar to total 100% with segments representing % of total sleep time spent in each sleep stage that night (deep, REM, light).
Currently, I'm using 3 number properties to enter the % of time spent in each stage into the database.
I've only had success using the "grouping" option in bar charts to display multiple groups in one bar/day when the properties being grouped are categorical, like select or multi-select, not numbers.
How can I do this?
