\qmlclass PieSlice QPieSlice
PieSlice defines the properties of a single slice in a PieSeries. The element should be used
as a child for a PieSeries. For example:
\snippet ../examples/qmlpiechart/qml/qmlpiechart/main.qml 2
An alternative (dynamic) method for adding slices to a PieSeries is using PieSeries.append
method.
\snippet ../examples/qmlpiechart/qml/qmlpiechart/main.qml 4
In that case you may want to use PieSeries.at or PieSeries.find to access the properties of
an individual PieSlice instance.
