Dose marker colours

Detected doses are added here automatically. New dose values get an automatic colour based on their numeric value, then you can override the colour if needed.

The Chunkr Choon

Turns the current data into a short tune. Lower weight plays a higher note. Every day on the x axis is one beat of time. Gaps between readings last for the same number of beats. Jabs still play chords even when no weight is entered.
