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 QXYSeries and QAbstractItemModel derived model object.
|
|
|
It is possible to use both QAbstractItemModel and QXYSeries model API. QXYModelMapper makes sure that QXYSeries and the model are kept in sync.
|
|
|
Note: used model has to support adding/removing rows/columns and modifying the data of the cells.

HXYModelMapper keeps the series and the model in sync.
