Each circle represents a hospital and its size represents the number of overnight stays for the selected category. The bigger the circle, the greater the number of overnight stays for that hospital.
The average length of stay is shown by the relative position up and down the chart. The higher the circle, the higher the average length of stay.
Overlapping circles indicate more than one hospital with the same average length of stay.
Hovering the cursor over a circle highlights that hospital’s performance over time.
