\brief Vertical model mapper for bar series

\mainclass
|
|
|
|
|
|
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 QBoxPlotSeries and QAbstractItemModel derived model object.
|
|
|
Model mapper maintains equal size of all the BarSets.
|
|
|
Note: used model has to support adding/removing rows/columns and modifying the data of the cells.

\mainclass
|
|
|
|
|
|
VBoxPlotModelMapper allows you to use your own QAbstractItemModel derived model with data in columns as a data source
|
|
|
for any box-and-whiskers series. It is possible to use both QAbstractItemModel and box-and-whiskers series data API to
|
|
|
manipulate data.
|
|
|
VBoxPlotModelMapper keeps the series and the model in sync.
|
|
|
|
|
|
The following QML example would create a box-and-whiskers series with three box sets (assuming the
|
|
|
model has at least four columns). Each box set would contain data starting from row 1. The name of a set would be
|
|
|
defined by the horizontal header (of the column).

|
|
\code
|
|
|
BarSeries {
|
|
|
VBarModelMapper {
|
|
|
model: myCustomModel // QAbstractItemModel derived implementation
|
|
|
firstBarSetColumn: 1
|
|
|
lastBarSetColumn: 3
|
|
|
firstRow: 1
|
|
|
}
|
|
