RadPieChart draws its slices in the same order as the corresponding data items appear in the ItemsSource. If you bind a ListBox to the same data, it should be ordered the same way. You can influence that order by reverting the pie direction. This is done by setting the PieSeries.AngleRange.SweepDirection
property to Counterclockwise
. If you want to order pie slices in a specific way, you just need to arrange the data items in the ItemsSource the same way.
Given that you want to display male/female ratios for different neighborhoods, you may also consider using a different visualization, such as horizontal a Stacked100 Bar Chart. (See attached screenshot and sample project).
I hope this helps.
