\brief Horizontal model mapper for QXYSeries. | ||||
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. | ||||
