r1397 | Model mappers allow you to use QAbstractItemModel derived models as a data source for a chart series. | ||
|
r1378 | 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. | ||
|
r1340 | It is possible to use both QAbstractItemModel and QPieSeries model API. QHPieModelMapper makes sure that Pie and the model are kept in sync. | ||

\qmlclass HPieModelMapper QHPieModelMapper | ||||
HPieModelMapper allows you to use your own QAbstractItemModel derived model with data in rows as a data source | ||||
for a pie series. It is possible to use both QAbstractItemModel and PieSeries data API to manipulate data. | ||||
HPieModelMapper 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 columns). Each slice would contain a label from row 1 and a value from row 2. | ||||
\code | ||||
HPieModelMapper { | ||||
series: pieSeries | ||||
model: customModel | ||||
labelsRow: 1 | ||||
valuesRow: 2 | ||||
firstColumn: 1 | ||||
columnCount: 4 | ||||
} | ||||
\endcode | ||||
