详细描述
The QScatterDataItem class provides a container for resolved data to be added to scatter graphs.
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.
参见 QScatterDataProxy and Qt Data Visualization C++ Classes.
成员函数
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.
参见 setPosition().
QQuaternion QScatterDataItem::rotation() const
Returns the rotation of this data item.
参见 setRotation().
void QScatterDataItem::setPosition(const QVector3D &pos)
Sets the position pos for this data item.
参见 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.
参见 rotation().
void QScatterDataItem::setX(float value)
Sets the x-coordinate of the item position to the value value.
参见 x().
void QScatterDataItem::setY(float value)
Sets the y-coordinate of the item position to the value value.
参见 y().
void QScatterDataItem::setZ(float value)
Sets the z-coordinate of the item position to the value value.
参见 z().
float QScatterDataItem::x() const
Returns the x-coordinate of the position of this data item.
参见 setX().
float QScatterDataItem::y() const
Returns the y-coordinate of the position of this data item.
参见 setY().
float QScatterDataItem::z() const
Returns the z-coordinate of the position of this data item.
参见 setZ().
QScatterDataItem &QScatterDataItem::operator=(const QScatterDataItem &other)
Assigns a copy of other to this object.
