\class QVPieModelMapper

Marek Rosa
Updated mapper classes descriptions
 r1397 Model mappers allow you to use QAbstractItemModel derived models as a data source for a chart series.
Marek Rosa
Model mappers docs updated
 r1378 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.
Marek Rosa
Added documentation for PieModelMapper classes
 r1340 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.

\qmlclass VPieModelMapper QVPieModelMapper
VPieModelMapper allows you to use your own QAbstractItemModel derived model with data in columns as a data source
for a pie series. It is possible to use both QAbstractItemModel and PieSeries data API to manipulate data.
VPieModelMapper keeps the Pie and the model in sync.
The following QML example would create a pie series with four slices (assuming the model has at least five rows).
Each slice would contain a label from column 1 and a value from column 2.
\code
VPieModelMapper {
series: pieSeries
model: customModel
labelsColumn: 1
valuesColumn: 2
firstRow: 1
rowCount: 4
}
\endcode
