Property Documentation

barSeriesMargin : QSizeF

Margin between series columns in X and Z dimensions. Sensible values are on the range [0,1).

Preset to (0.0, 0.0) by default. This property enables showing bars from different series side by side, but with space between columns.

Access functions:

Notifier signal:

See also barSpacing.

barSpacing : QSizeF

Bar spacing in the X and Z dimensions.

Preset to (1.0, 1.0) by default. Spacing is affected by the barSpacingRelative property.

Access functions:

Notifier signal:

See also barSpacingRelative, multiSeriesUniform, and barSeriesMargin.

barSpacingRelative : bool

This property holds whether spacing is absolute or relative to bar thickness.

If it is true, the value of 0.0 means that the bars are placed side-to-side, 1.0 means that a space as wide as the thickness of one bar is left between the bars, and so on. Preset to true.

Access functions:

Notifier signal:

barThickness : float

This property holds the bar thickness ratio between the X and Z dimensions.

The value 1.0 means that the bars are as wide as they are deep, whereas 0.5 makes them twice as deep as they are wide. Preset to 1.0 by default.

Access functions:

Notifier signal:

columnAxis : QCategory3DAxis*

This property holds the axis attached to the active column.

Sets the axis of the active column to axis. Implicitly calls addAxis() to transfer the ownership of the axis to this graph.

If axis is null, a temporary default axis with no labels is created. This temporary axis is destroyed if another axis is set explicitly to the same orientation.

Access functions:

Notifier signal:

See also addAxis() and releaseAxis().

floorLevel : float

This property holds the floor level for the bar graph in Y-axis data coordinates.

The actual floor level will be restricted by the Y-axis minimum and maximum values. Defaults to zero.

Access functions:

Notifier signal:

multiSeriesUniform : bool

This property holds whether bars are to be scaled with proportions set to a single series bar even if there are multiple series displayed.

If set to true, bar spacing will be correctly applied only to the X-axis. Preset to false by default.

Access functions:

Notifier signal:

primarySeries : QBar3DSeries*

This property holds the primary series of the graph.

Sets series as the primary series of the graph. The primary series determines the row and column axis labels when the labels are not explicitly set to the axes.

If the specified series is not yet added to the graph, setting it as the primary series will also implicitly add it to the graph.

If the primary series itself is removed from the graph, this property resets to default.

If series is null, this property resets to default. Defaults to the first added series or zero if no series are added to the graph.

Access functions:

Notifier signal:

rowAxis : QCategory3DAxis*

This property holds the axis attached to the active row.

Sets the axis of the active row to axis. Implicitly calls addAxis() to transfer the ownership of the axis to this graph.

If axis is null, a temporary default axis with no labels is created. This temporary axis is destroyed if another axis is set explicitly to the same orientation.

Access functions:

Notifier signal:

See also addAxis() and releaseAxis().

[read-only] selectedSeries : QBar3DSeries* const

This property holds the selected series or a null value.

If selectionMode has the SelectionMultiSeries flag set, this property holds the series that owns the selected bar.

Access functions:

Notifier signal:

valueAxis : QValue3DAxis*

Sets the active value axis (the Y-axis) to axis. Implicitly calls addAxis() to transfer the ownership of axis to this graph.

If axis is null, a temporary default axis with no labels and an automatically adjusting range is created. This temporary axis is destroyed if another axis is set explicitly to the same orientation.

Access functions:

Notifier signal:

See also addAxis() and releaseAxis().
