\brief part of QtCommercial chart API.

\mainclass
|
|
|
|
|
|
Model mappers allow you to use QAbstractItemModel derived models as a data source for a chart series.
|
|
|
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.
