Model mappers enable using a data model derived from the QAbstractItemModel class as a data source for a chart. A vertical model mapper is used to create a connection between a data model and a QBoxPlotSeries object, so that each column in the data model defines a box-and-whiskers item and each row 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 bar 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. \sa QHBoxPlotModelMapper */ /*! \qmltype VBoxPlotModelMapper \instantiates QVBoxPlotModelMapper \inqmlmodule QtCharts \brief Vertical model mapper for box plot series. The VBoxPlotModelMapper type enables using a data model derived from the QAbstractItemModel class as a data source for a chart. A vertical model mapper is used to create a connection between a data model and a BoxPlotSeries type, so that each column in the data model defines a box-and-whiskers item and each row 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.

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 columns). Each box-and-whiskers item contains data starting from row 1. The name of an item is defined by the column header. \code BoxPlotSeries { VBoxPlotModelMapper { model: myCustomModel // QAbstractItemModel derived implementation firstBoxSetColumn: 1 lastBoxSetColumn: 3 firstRow: 1 } } \endcode \sa HBoxPlotModelMapper */ /*! \property QVBoxPlotModelMapper::series \brief The box plot series that is used by the mapper.
