\brief Horizontal model mapper for bar series.

|
\mainclass
|
|
|
|
|
|
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 QAbstractBarSeries and QAbstractItemModel derived model object.
|
|
|
Model mapper maintains equal size of all the BarSets.
|
|
|
Adding/removing value from the BarSet causes the the same change in the rest of the BarSets added to the same series.
|
|
|
\note Used model has to support adding/removing rows/columns and modifying the data of the cells.
