|
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 QPieSeries and QAbstractItemModel derived model object that keeps the consecutive pie slices data in rows.
|
|
|
It is possible to use both QAbstractItemModel and QPieSeries model API. QHPieModelMapper makes sure that Pie and the model are kept in sync.
|
|
|
NOTE: used model has to support adding/removing rows/columns and modifying the data of the cells.
