Metadata Plot (IMAGE) BMC (BioMed Central) Caption This is a plot demonstrating how much data was collected on the subjects, laying out how one subject spent every minute of their day over four months. The plot is laid out like a 24 hour clock, where the radial distances of each colored shape reflect the probability the subject was performing an action at a given time. For example, at 3 PM, the subject had roughly a 50 percent chance of actively working (light green), a 10 percent chance of eating a snack (orange), a 10 percent chance of pursuing a leisure activity (dark blue), and a 5 percent chance of writing an email (dark green).
