Property Documentation

axisX : QValue3DAxis*

This property holds the active x-axis.

Sets axis as the active x-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 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().

axisY : QValue3DAxis*

This property holds the active y-axis.

Sets axis as the active y-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 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().

axisZ : QValue3DAxis*

This property holds the active z-axis.

Sets axis as the active z-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 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().

flipHorizontalGrid : bool

This property holds whether the horizontal axis grid is displayed on top of the graph rather than on the bottom.

In some use cases, the horizontal axis grid is mostly covered by the surface, so it can be more useful to display the horizontal axis grid on top of the graph rather than on the bottom. A typical use case for this is showing 2D spectrograms using orthographic projection with a top-down viewpoint.

If false, the horizontal axis grid and labels are drawn on the horizontal background of the graph. If true, the horizontal axis grid and labels are drawn on the opposite side of the graph from the horizontal background. Defaults to false.

Access functions:

Notifier signal:

[read-only] selectedSeries : QSurface3DSeries* const

This property holds the selected series or null.

If selectionMode has MultiSeries set, this property holds the series which owns the selected point.
