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.

class PySide6.QtCharts.QHBoxPlotModelMapper([parent=None])#
Parameters:

parent – PySide6.QtCore.QObject

Constructs a mapper object that is a child of parent.

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property PᅟySide6.QtCharts.QHBoxPlotModelMapper.columnCount: int#

This property holds The number of columns of the model that are mapped as the data for the box plot series..

The minimum and default value is -1 (number limited to the number of columns in the model).

Access functions:
property PᅟySide6.QtCharts.QHBoxPlotModelMapper.firstBoxSetRow: int#

This property holds The row of the model that is used as the data source for the first box-and-whiskers item..

The default value is -1 (invalid mapping).

Access functions:
property PᅟySide6.QtCharts.QHBoxPlotModelMapper.firstColumn: int#

This property holds The column of the model that contains the first values of the box-and-whiskers items in the box plot series..

The minimum and default value is 0.

Access functions:
property PᅟySide6.QtCharts.QHBoxPlotModelMapper.lastBoxSetRow: int#

This property holds The row of the model that is used as the data source for the last box-and-whiskers item..

The default value is -1 (invalid mapping).

Access functions:
property PᅟySide6.QtCharts.QHBoxPlotModelMapper.model: PySide6.QtCore.QAbstractItemModel#

This property holds The model that is used by the mapper..

Access functions:
property PᅟySide6.QtCharts.QHBoxPlotModelMapper.series: PySide6.QtCharts.QBoxPlotSeries#

This property holds The box plot series that is used by the mapper..

All the data in the series is discarded when it is set to the mapper. When a new series is specified, the old series is disconnected (but it preserves its data).
