38 \brief Horizontal model mapper for box plot series.
39
40 Model mappers allow you to use QAbstractItemModel derived models as a data source for a chart series.
41 Horizontal model mapper is used to create a connection between QBoxPlotSeries and QAbstractItemModel derived model object.
42 Model mapper maintains equal size of all the QBoxSets.
43 \note used model has to support adding/removing rows/columns and modifying the data of the cells.

50 \brief Horizontal model mapper for box plot series.
51
52 HBoxPlotModelMapper allows you to use your own QAbstractItemModel derived model with data in
53 rows as a data source for any box-and-whiskers series. It is possible to use both
54 QAbstractItemModel and box-and-whiskers series data API to manipulate data. HBoxPlotModelMapper
55 keeps the series and the model in sync.
56
57 The following QML example would create a box-and-whiskers series with three box sets (assuming
58 the model has at least four rows). Each box set would contain data starting from column 1. The
59 name of a set would be defined by the vertical header (of the row).
60 \code
61 BoxPlotSeries {
62 HBoxPlotModelMapper {
63 model: myCustomModel // QAbstractItemModel derived implementation
64 firstBoxSetRow: 1
65 lastBoxSetRow: 3
66 firstColumn: 1
67 }
