PieRenderer must be placed inside a PolarPlot component. It draws each data item as a circular sector whose angle is proportional to the data value. If the GetLabel method of Series object returns InnerLabel or OuterLabel strings, they are drawn respectively inside or outside of their corresponding sector.

If series' IsEmphasized method returns true for a data item, its respective slice is drawn detached from the pie. If using PieSeries to specify data, you can assign indices of detached slices through the DetachedSlices property.
