\brief Horizontal model mapper for QXYSeries.
\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 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.

HXYModelMapper allows you to use your own QAbstractItemModel derived model with data in rows as
