Detailed Description

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 data model and QBoxPlotSeries object, so that each row in the data model defines a box-and-whiskers item and each column maps to the range and three median values of the box-and-whiskers item.

Both model and series properties can be used to manipulate the data. The model mapper keeps the series and the data model in sync.

The model mapper ensures that all the box-and-whiskers items in the box plot series have equal sizes. Therefore, adding or removing a value from a box-and-whiskers item causes the same change to be made in all the box-and-whiskers items in the box plot series.

Member Function Documentation

QHBoxPlotModelMapper::QHBoxPlotModelMapper(QObject *parent = nullptr)

Constructs a mapper object that is a child of parent.

[signal] void QHBoxPlotModelMapper::columnCountChanged()

This signal is emitted when the number of columns changes.

Note: Notifier signal for property columnCount.

[signal] void QHBoxPlotModelMapper::firstBoxSetRowChanged()

This signal is emitted when the first box-and-whiskers item row changes.

Note: Notifier signal for property firstBoxSetRow.

[signal] void QHBoxPlotModelMapper::firstColumnChanged()

This signal is emitted when the first column changes.

Note: Notifier signal for property firstColumn.

[signal] void QHBoxPlotModelMapper::lastBoxSetRowChanged()

This signal is emitted when the last box-and-whiskers item row changes.

Note: Notifier signal for property lastBoxSetRow.

[signal] void QHBoxPlotModelMapper::modelReplaced()

This signal is emitted when the model that the mapper is connected to changes.

Note: Notifier signal for property model.

[signal] void QHBoxPlotModelMapper::seriesReplaced()

This signal is emitted when the series that the mapper is connected to changes.

Note: Notifier signal for property series.
