QScatterDataItem Class▲

  • Header: QScatterDataItem

  • Since: QtDataVisualization 1.0

  • CMake:

    find_package(Qt6 REQUIRED COMPONENTS DataVisualization)

    target_link_libraries(mytarget PRIVATE Qt6::DataVisualization)

  • qmake: QT += datavisualization

Detailed Description▲

A scatter data item holds the data for a single rendered item in a scatter graph. Scatter data proxies parse data into QScatterDataItem instances for visualization.

Member Function Documentation▲

 

QScatterDataItem::QScatterDataItem()▲

Constructs a scatter data item.

QScatterDataItem::QScatterDataItem(const QVector3D &position)▲

Constructs a scatter data item at the position position.

QScatterDataItem::QScatterDataItem(const QVector3D &position, const QQuaternion &rotation)▲

Constructs a scatter data item at the position position with the rotation rotation.

QScatterDataItem::QScatterDataItem(const QScatterDataItem &other)▲

Constructs a copy of other.

QScatterDataItem::~QScatterDataItem()▲

Deletes a scatter data item.

QVector3D QScatterDataItem::position() const▲

Returns the position of this data item.

See Also▲

See also setPosition()

QQuaternion QScatterDataItem::rotation() const▲

Returns the rotation of this data item.

See Also▲

See also setRotation()

void QScatterDataItem::setPosition(const QVector3D &pos)▲

Sets the position pos for this data item.

See Also▲

See also position()

void QScatterDataItem::setRotation(const QQuaternion &rot)▲

Sets the rotation rot for this data item. The value of rot should be a normalized QQuaternion. If the series also has rotation, item rotation is multiplied by it. Defaults to no rotation.

void QScatterDataItem::setX(float value)▲

Sets the x-coordinate of the item position to the value value.

See Also▲

See also x()

void QScatterDataItem::setY(float value)▲

Sets the y-coordinate of the item position to the value value.

See Also▲

See also y()

void QScatterDataItem::setZ(float value)▲

Sets the z-coordinate of the item position to the value value.

See Also▲

See also z()

float QScatterDataItem::x() const▲

Returns the x-coordinate of the position of this data item.

See Also▲

See also setX()

float QScatterDataItem::y() const▲

Returns the y-coordinate of the position of this data item.

See Also▲

See also setY()

float QScatterDataItem::z() const▲

Returns the z-coordinate of the position of this data item.

See Also▲

See also setZ()

QScatterDataItem &QScatterDataItem::operator=(const QScatterDataItem &other)▲

Assigns a copy of other to this object.
