| 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 | ||||

| VBoxPlotModelMapper { | ||||
| model: myCustomModel // QAbstractItemModel derived implementation | ||||
| firstBoxSetColumn: 1 | ||||
| lastBoxSetColumn: 3 | ||||
| firstRow: 1 | ||||
| } | ||||
