QScatterDataItem::
position
() const
Returns the position of this data item.
另请参阅 setPosition ().
Returns the rotation of this data item.
另请参阅 setRotation ().

QScatterDataItem::
setPosition
(const
QVector3D
&
pos
)
Sets the position pos for this data item.
另请参阅 position ().

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.
