Detailed Description

This class manages the series specific visual elements, as well as the series data (via a data proxy).

If no data proxy is set explicitly for the series, the series creates a default proxy. Setting another proxy will destroy the existing proxy and all data added to it.

QBar3DSeries supports the following format tags for setItemLabelFormat() :

@rowTitle	Title from row axis
@colTitle	Title from column axis
@valueTitle	Title from value axis
@rowIdx	Visible row index. Localized using the graph locale.
@colIdx	Visible column index. Localized using the graph locale.
@rowLabel	Label from row axis
@colLabel	Label from column axis
@valueLabel	Item value formatted using the format of the value axis attached to the graph. For more information, see labelFormat .
@seriesName	Name of the series
%<format spec>	Item value in the specified format. Formatted using the same rules as labelFormat .

For example:

proxy.setItemLabelFormat(QStringLiteral("@valueTitle for (@rowLabel, @colLabel): %.1f"))

class PySide6.QtDataVisualization.QBar3DSeries(dataProxy[, parent=None])

PySide6.QtDataVisualization.QBar3DSeries([parent=None])

Parameters

• dataProxy – PySide6.QtDataVisualization.QBarDataProxy

• parent – PySide6.QtCore.QObject

Constructs a bar 3D series with the data proxy dataProxy and the parent parent.

Constructsa bar 3D series with the parent parent.

PySide6.QtDataVisualization.QBar3DSeries.dataProxy()

Return type

PySide6.QtDataVisualization.QBarDataProxy

This property holds The active data proxy..

The series assumes ownership of any proxy set to it and deletes any previously set proxy when a new one is added. The proxy cannot be null or set to another series.

PySide6.QtDataVisualization.QBar3DSeries.dataProxyChanged(proxy)

Parameters

proxy – PySide6.QtDataVisualization.QBarDataProxy

static PySide6.QtDataVisualization.QBar3DSeries.invalidSelectionPosition()

Return type

PySide6.QtCore.QPoint

Returns an invalid position for selection. This position is set to the selectedBar property to clear the selection from this series.

clearSelection()

PySide6.QtDataVisualization.QBar3DSeries.meshAngle()

Return type

float

This property holds The series rotation angle in degrees..

Setting this property is equivalent to the following call:

setMeshRotation(QQuaternion::fromAxisAndAngle(0.0f, 1.0f, 0.0f, angle))

Note

When reading this property, it is calculated from the meshRotation value using floating point precision and always returns a value from zero to 360 degrees.

PySide6.QtDataVisualization.QBar3DSeries.meshAngleChanged(angle)

Parameters

angle – float

PySide6.QtDataVisualization.QBar3DSeries.selectedBar()

Return type

PySide6.QtCore.QPoint

This property holds The bar in the series that is selected..

PySide6.QtDataVisualization.QBar3DSeries.selectedBarChanged(position)

Parameters

position – PySide6.QtCore.QPoint

PySide6.QtDataVisualization.QBar3DSeries.setDataProxy(proxy)

Parameters

proxy – PySide6.QtDataVisualization.QBarDataProxy

This property holds The active data proxy..

The series assumes ownership of any proxy set to it and deletes any previously set proxy when a new one is added. The proxy cannot be null or set to another series.

PySide6.QtDataVisualization.QBar3DSeries.setMeshAngle(angle)

Parameters

angle – float

This property holds The series rotation angle in degrees..

Setting this property is equivalent to the following call:

setMeshRotation(QQuaternion::fromAxisAndAngle(0.0f, 1.0f, 0.0f, angle))

Note

When reading this property, it is calculated from the meshRotation value using floating point precision and always returns a value from zero to 360 degrees.

PySide6.QtDataVisualization.QBar3DSeries.setSelectedBar(position)

Parameters

position – PySide6.QtCore.QPoint

This property holds The bar in the series that is selected..
