    \class QHBoxPlotModelMapper
    \inmodule QtCharts
    \brief The QHBoxPlotModelMapper class is a horizontal model mapper for box
    plot series.

    Model mappers enable using a data model derived from the QAbstractItemModel
    class as a data source for a chart. A horizontal model mapper is used to
    create a connection between a data model and QBoxPlotSeries object, so that
    each row in the data model defines a box-and-whiskers item and each column
    maps to the range and three median values of the box-and-whiskers item.

    Both model and series properties can be used to manipulate the
    data. The model mapper keeps the series and the data model in sync.

    The model mapper ensures that all the box-and-whiskers items in the box plot
    series have equal sizes. Therefore, adding or removing a value from a
    box-and-whiskers item causes the same change to be made in all the
    box-and-whiskers items in the box plot series.

    \brief Horizontal model mapper for box plot series.

    The HBoxPlotModelMapper type enables using a data model derived from the
    QAbstractItemModel class as a data source for a chart. A horizontal model
    mapper is used to create a connection between a data model and a
    BoxPlotSeries type, so that each row in the data model defines a
    box-and-whiskers item and each column maps to the range and three median
    values of the box-and-whiskers item.

    Both model and series properties can be used to manipulate the data. The
    model mapper keeps the series and the data model in sync.

    The model mapper ensures that all the box-and-whiskers items in the box plot
    series have equal sizes. Therefore, adding or removing a value from a
    box-and-whiskers item causes the same change to be made in all the
    box-and-whiskers items in the box plot series.

    The following QML code snippet creates a box plot series with three
    box-and-whiskers items (assuming the model has at least four rows). Each
    box-and-whiskers item contains data starting from column 1. The name of an
    item is defined by the row header.
    \code
        BoxPlotSeries {
            HBoxPlotModelMapper {
                model: myCustomModel // QAbstractItemModel derived implementation
                firstBoxSetRow: 1
                lastBoxSetRow: 3
                firstColumn: 1
            }
        }
    \endcode
