\class QVPieModelMapper
\brief part of QtCommercial chart API.
\mainclass
Model mappers allow you to use QAbstractItemModel derived models as a data source for a chart series.
Vertical model mapper is used to create a connection between QPieSeries and QAbstractItemModel derived model object that keeps the consecutive pie slices data in columns.
It is possible to use both QAbstractItemModel and QPieSeries model API. QVPieModelMapper 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.
