详细描述

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 scatter graphs.

[constexpr noexcept] QScatterDataItem:: QScatterDataItem ()

Default constructor for scatter data item.

[explicit noexcept] QScatterDataItem:: QScatterDataItem (const QVector3D & position )

Constructs scatter data item with position position .

[explicit noexcept] QScatterDataItem:: QScatterDataItem ( float x , float y , float z )

Constructs a scatter data item at the position specified by x , y ，和 z .

[explicit noexcept] QScatterDataItem:: QScatterDataItem (const QVector3D & position , const QQuaternion & rotation )

Constructs scatter data item with position position and rotation rotation .

[noexcept] QVector3D QScatterDataItem:: position () const

Returns the position of this data item.

另请参阅 setPosition ().

QQuaternion QScatterDataItem:: rotation () const

Returns the rotation of this data item.

另请参阅 setRotation ().

[noexcept] void QScatterDataItem:: setPosition (const QVector3D & pos )

Sets the position pos for this data item.

另请参阅 position ().

[noexcept] 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.

另请参阅 rotation ().

[noexcept] void QScatterDataItem:: setX ( float value )

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

另请参阅 x ().

[noexcept] void QScatterDataItem:: setY ( float value )

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

另请参阅 y ().

[noexcept] void QScatterDataItem:: setZ ( float value )

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

另请参阅 z ().

[noexcept] float QScatterDataItem:: x () const

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

另请参阅 setX ().

[noexcept] float QScatterDataItem:: y () const

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

另请参阅 setY ().

[noexcept] float QScatterDataItem:: z () const

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

另请参阅 setZ ().
