\class QVXYModelMapper
\inmodule Qt Charts
\brief Vertical model mapper for QXYSeries.
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 QXYSeries and QAbstractItemModel derived model object.
It is possible to use both QAbstractItemModel and QXYSeries model API. QXYModelMapper makes sure that QXYSeries and the model are kept in sync.
Note: used model has to support adding/removing rows/columns and modifying the data of the cells.
