r2517 | 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. | ||||
