Model mappers allow you to use QAbstractItemModel derived models as a data source for a chart series.
Vertical model mapper is used to create a connection between QBoxPlotSeries and QAbstractItemModel derived model object.
Model mapper maintains equal size of all the QBoxSets.

\brief Vertical model mapper for box plot series.
VBoxPlotModelMapper allows you to use your own QAbstractItemModel derived model with data in
columns as a data source for any box-and-whiskers series. It is possible to use both
QAbstractItemModel and box-and-whiskers series data API to manipulate data. VBoxPlotModelMapper
keeps the series and the model in sync.
The following QML example would create a box-and-whiskers series with three box sets (assuming
the model has at least four columns). Each box set would contain data starting from row 1. The
name of a set would be defined by the horizontal header (of the column).
\code
BoxPlotSeries {
VBoxPlotModelMapper {
model: myCustomModel // QAbstractItemModel derived implementation
firstBoxSetColumn: 1
lastBoxSetColumn: 3
firstRow: 1
}
}
\endcode
