                 \brief The Axis element is used for manipulating chart's axes
                 There is only one x Axis, however there can be multiple y axes on a ChartView.
                 Each chart series can be bound to exactly one Y axis and the shared common X axis.
                 Axis can be setup to show axis line with tick marks, grid lines and shades.
                 To access Axes you can use ChartView API. For example:
                 \code
                     ChartView {
                         axisX.min: 0
                         axisX.max: 3

                         axisY.min: 0
                         axisY.max: 4
                         // Add a few series...

                 \class QPieSlice
                 \brief Defines a slice in pie series.
                 This object defines the properties of a single slice in a QPieSeries.
                 In addition to the obvious value and label properties the user can also control
                 the visual appearance of a slice. By modifying the visual appearance also means that
                 the user is overriding the default appearance set by the theme.
                 Note that if the user has customized slices and theme is changed all customizations will be lost.
                 To enable user interaction with the pie some basic signals are provided about clicking and hovering.

                 \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.
