The pie chart labeled "Distribution Of Parenting Time" is calculated by using values for NP Time and Actual Hours. The remaining time is assigned to the other parent.

The parent who's time is being tracked is Parent 1.

For the current year the pie-graph displays the percentage of time that you've had year-to-date, calculated against the time-to-date versus your parenting time.

For previous years the entire year is taken into account, calculating the percentage of time that you had that year relative to the total time for the year.
