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).

setClose()

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

setFirstSetSection()

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

setHigh()

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

setLastSetSection()

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

setLow()

PySide6.QtCharts.QCandlestickModelMapper.model()

Return type

PySide6.QtCore.QAbstractItemModel

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

setOpen()

PySide6.QtCharts.QCandlestickModelMapper.orientation()

Return type

Orientation

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

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.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).

close()

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.

firstSetSection()

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).

high()

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.

lastSetSection()

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).

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).
