Intensity level distribution

This chart shows the distribution of the five levels of pain intensity, from the lowest (green) to the highest (red). You can see the intensity level name by hovering your mouse over it.

Binary distribution

This chart allows you to visualise the distribution of the presence of pain over time. You can visualise its absence in green and its presence in red. You can see the details by hovering your mouse over it.

Intensity level plot

This plot shows the trend of pain value over time on the five intensity levels, from 0 to 4.
