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.

The object mesh set via the QAbstract3DSeries::mesh property defines the selection pointer shape in a surface series.

QSurface3DSeries supports the following format tags for QAbstract3DSeries::setItemLabelFormat():

@xTitle	Title from x-axis
@yTitle	Title from y-axis
@zTitle	Title from z-axis
@xLabel	Item value formatted using the format of the x-axis. For more information, see QValue3DAxis::setLabelFormat().
@yLabel	Item value formatted using the format of the y-axis. For more information, see QValue3DAxis::setLabelFormat().
@zLabel	Item value formatted using the format of the z-axis. For more information, see QValue3DAxis::setLabelFormat().
@seriesName	Name of the series

For example:

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

Member Type Documentation

enum QSurface3DSeries::DrawFlagflags QSurface3DSeries::DrawFlags

The drawing mode of the surface. Values of this enumeration can be combined with the OR operator.

Constant	Value	Description
QSurface3DSeries::DrawWireframe	1	Only the grid is drawn.
QSurface3DSeries::DrawSurface	2	Only the surface is drawn.
QSurface3DSeries::DrawSurfaceAndWireframe	DrawWireframe | DrawSurface	Both the surface and grid are drawn.

The DrawFlags type is a typedef for QFlags<DrawFlag>. It stores an OR combination of DrawFlag values.

Member Function Documentation

QSurface3DSeries::QSurface3DSeries(QSurfaceDataProxy *dataProxy, QObject *parent = nullptr)

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

QSurface3DSeries::QSurface3DSeries(QObject *parent = nullptr)

Constructs a surface 3D series with the parent parent.

[virtual] QSurface3DSeries::~QSurface3DSeries()

Deletes the surface 3D series.

[static] QPoint QSurface3DSeries::invalidSelectionPosition()

Returns the QPoint signifying an invalid selection position. This is set to the selectedPoint property to clear the selection from this series.

See also QAbstract3DGraph::clearSelection().

void QSurface3DSeries::setSelectedPoint(const QPoint &position)

Selects a surface grid point at the position position in the data array of the series specified by a row and a column.

Only one point can be selected at a time.

To clear selection from this series, invalidSelectionPosition() is set as position. If this series is added to a graph, the graph can adjust the selection according to user interaction or if it becomes invalid.

Removing rows from or inserting rows to the series before the row of the selected point will adjust the selection so that the same point will stay selected.

Note: Setter function for property selectedPoint.
