Scaling of Sleep Graphs

Hi! An option to scale the sleep graphs in order to accurately visually compare cycles between consecutive nights would be really awesome :slight_smile:!

For example, in the screenshot below, I have an 11.5 hour :eyes: vs an 5.5 hour :expressionless: vs an 8 hour :smile: sleep (see Iā€™m on this app for a reason). Iā€™d really like to see how REM cycles compare, but the visual is skewed on account of lack of scaling.
