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
.
- 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).
See also
- PySide6.QtCharts.QCandlestickModelMapper.model()¶
- Return type
This property Defines the model that is used by the mapper..
- PySide6.QtCharts.QCandlestickModelMapper.modelReplaced()¶
- 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
- 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 ( Horizontal
) or from columns ( Vertical
).
- PySide6.QtCharts.QCandlestickModelMapper.series()¶
- Return type
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.seriesReplaced()¶
- PySide6.QtCharts.QCandlestickModelMapper.setClose(close)¶
- 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.
See also
- 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).
See also
- PySide6.QtCharts.QCandlestickModelMapper.setLastSetSection(lastSetSection)¶
- 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.
See also
- 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).
See also
- PySide6.QtCharts.QCandlestickModelMapper.setModel(model)¶
- Parameters
This property Defines the model that is used by the mapper..
- PySide6.QtCharts.QCandlestickModelMapper.setOpen(open)¶
- Parameters
open – int
Sets the row/column of the model that contains the open
values of the sets in the series. Default value is -1 (invalid mapping).

- PySide6.QtCharts.QCandlestickModelMapper.setSeries(series)¶
- Parameters
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.setTimestamp(timestamp)¶
- Parameters
timestamp – int
Sets the row/column of the model that contains the timestamp
values of the sets in the series. Default value is -1 (invalid mapping).
