| \class QHXYModelMapper |

| \brief The QHXYModelMapper class is a horizontal model mapper for line, |
| spline, and scatter series. |
| |
| Model mappers enable using a data model derived from the QAbstractItemModel |
| class as a data source for a chart. A horizontal model mapper is used to |
| create a connection between a line, spline, or scatter series and the data |
| model that holds the consecutive data point coordinates on rows. |
| |
| Both model and series properties can be used to manipulate the data. The |
| model mapper keeps the series and the data model in sync. |
