I made a google sheet to track some daily goals of mine, such as doing Duolingo or having good posture. The first column is the task, the following are daily grades with some notes, so it looks sort of like:
|A did yoga
I was thinking it'd be nice to color code it based on if I give myself an F too many times in a row. So on this third day here, it'd look at itself and the previous 2 entries and see they all start with F, and be red. Then the following day, I do Duolingo and mark an A, that entry will not be red.
I'm not sure where to start with this, any help is much appreciated.
