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 | ||||
} | ||||
} | ||||
