r1397 | Model mappers allow you to use QAbstractItemModel derived models as a data source for a chart series. | ||
|
Marek Rosa
|
r1378 | Horizontal model mapper is used to create a connection between QBarSeries and QAbstractItemModel derived model object. | ||
| Curently it is NOT possible to use both QAbstractItemModel and QBarSeries model API. | ||||
| When the series is set to the mapper the QBarSeries and QBarSet API that affect the data (append, setValue, remove) should not be used. | ||||
| The model and the QBarSeries won't be kept in sync. Model API should be used to insert,remove,modify BarSets. | ||||
| NOTE: used model has to support adding/removing rows/columns and modifying the data of the cells. | ||||
