The Health Score page gives you more insight on how an account's health score is calculated and how much score it's getting from each component.
The top chart shows the average health score for this account trending monthly.
The health score breakdown section shows the different components included for calculating this account's health score and it's current contribution to the overall health score.
Particularly, the bar chart on the left shows the weighted score each component is contributing to the total health score vs. the missing weighted score each component could have contributed to the health score if that component is getting full 100 score.
And the pie chart on the right shows the current weight of each component within the health score.
The trend line shows the historical score (in absolute value from 0 - 100) of all the health components over a selected time frame.
