Detailed Description#
Model mappers allow the use of a QAbstractItemModel-derived model as a data source for a chart series, creating a connection between a QCandlestickSeries
and the model object. A model mapper maintains an equal size across all QCandlestickSets
.
Note
The model used must support adding and removing rows/columns and modifying the data of the cells.
- class PySide6.QtCharts.QCandlestickModelMapper([parent=None])#
- Parameters:
parent –
PySide6.QtCore.QObject
Constructs a model mapper object as 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.QCandlestickModelMapper.model: PySide6.QtCore.QAbstractItemModel#
This property Defines the model that is used by the mapper..
- Access functions:

()
- property PᅟySide6.QtCharts.QCandlestickModelMapper.series: PySide6.QtCharts.QCandlestickSeries#
This property Defines the QCandlestickSeries
object that is used by the mapper..
Note
All data in the series is discarded when it is set to the mapper. When a new series is specified, the old series is disconnected (preserving its data).

- PySide6.QtCharts.QCandlestickModelMapper.close()#
- Return type:
int
Returns the row/column of the model that contains the close values of the sets in the series. Default value is -1 (invalid mapping).

- PySide6.QtCharts.QCandlestickModelMapper.firstSetSection()#
- Return type:
int
Returns the section of the model that is used as the data source for the first candlestick set. Default value is -1 (invalid mapping).
See also
- PySide6.QtCharts.QCandlestickModelMapper.high()#
- Return type:
int
Returns the row/column of the model that contains the high values of the sets in the series. Default value is -1 (invalid mapping).
See also
- PySide6.QtCharts.QCandlestickModelMapper.lastSetSection()#
- Return type:
int
Returns the section of the model that is used as the data source for the last candlestick set. Default value is -1 (invalid mapping).
See also
- PySide6.QtCharts.QCandlestickModelMapper.low()#
- Return type:
int
Returns the row/column of the model that contains the low values of the sets in the series. Default value is -1 (invalid mapping).

Getter of property model
.
- PySide6.QtCharts.QCandlestickModelMapper.modelReplaced()#
Emitted when the model, to which the mapper is connected, has changed.

Notification signal of property model
.
- PySide6.QtCharts.QCandlestickModelMapper.open()#
- Return type:
int
Returns the row/column of the model that contains the open values of the sets in the series. Default value is -1 (invalid mapping).
See also
- abstract PySide6.QtCharts.QCandlestickModelMapper.orientation()#
- Return type:
Returns the orientation that is used when QCandlestickModelMapper
accesses the model. This determines whether the consecutive values of the set are read from rows (Qt::Horizontal) or from columns (Qt::Vertical).
- PySide6.QtCharts.QCandlestickModelMapper.series()#
- Return type:
See also
Getter of property series
.
- PySide6.QtCharts.QCandlestickModelMapper.seriesReplaced()#
Emitted when the series to which mapper is connected to has changed.

- Parameters:
close – int
Sets the row/column of the model that contains the close
values of the sets in the series. Default value is -1 (invalid mapping).
See also
- PySide6.QtCharts.QCandlestickModelMapper.setFirstSetSection(firstSetSection)#
- Parameters:
firstSetSection – int
Sets the section of the model that is used as the data source for the first candlestick set. Parameter firstSetSection
specifies the section of the model. Default value is -1.

- PySide6.QtCharts.QCandlestickModelMapper.setHigh(high)#
- Parameters:
high – int
Sets the row/column of the model that contains the high
values of the sets in the series. Default value is -1 (invalid mapping).

- Parameters:
lastSetSection – int
Sets the section of the model that is used as the data source for the last candlestick set. Parameter lastSetSection
specifies the section of the model. Default value is -1.

- PySide6.QtCharts.QCandlestickModelMapper.setLow(low)#
- Parameters:
low – int
Sets the row/column of the model that contains the low
values of the sets in the series. Default value is -1 (invalid mapping).
