详细描述

Spline graphs are used to show information as a series of data points connected by a curved or straight Catmull-Rom spline.

This class manages the spline specific visual elements.

Spline3DSeries extends the Scatter3DSeries API.

splineColor : QColor

This property holds the color of the spline.

访问函数：

QColor	splineColor () const
void	setSplineColor (QColor color )

通知程序信号：

void	splineColorChanged (QColor color )

splineKnotting : qreal

This property holds the knot parametrization of the spline.

This parameter can change the profile of the curve. The spline is classified as a uniform Catmull-Rom spline at a value of 0.0 , a centripetal Catmull-Rom spline at a value of 0.5 , and a chordal Catmull-Rom spline at a value of 1.0 .

值必须介于 0.0 and 1.0 。默认值为 0.5 .

访问函数：

qreal	splineKnotting () const
void	setSplineKnotting (qreal knotting )

通知程序信号：

void	splineKnottingChanged (qreal knotting )

splineLooping : bool

Determines whether the spline loops.

This adds a spline segment between the first and last points of the series connecting the spline into a loop.

默认值为 false

访问函数：

bool	isSplineLooping () const
void	setSplineLooping (bool looping )

通知程序信号：

void	splineLoopingChanged (bool looping )

splineResolution : int

This property holds the resolution of the segments spline.

The number of vertices per spline segment, which is defined as the part between two points.

Must be a value above 2 。默认值为 10 .

访问函数：

int	splineResolution () const
void	setSplineResolution (int resolution )

通知程序信号：

void	splineResolutionChanged (int resolution )

splineTension : qreal

This property holds the tension of the spline.

The spline uses maximum curvature for segments at a value of 0.0 Segments are completely straight at a value of 1.0 必须介于 0.0 and 1.0 默认值为 0.0

访问函数：

qreal	splineTension () const
void	setSplineTension (qreal tension )

通知程序信号：

void	splineTensionChanged (qreal tension )

splineVisible : bool

Visibility of the spline.

Visibility of the spline. The default value is true .

访问函数：

bool	isSplineVisible () const
void	setSplineVisible (bool draw )

通知程序信号：

void	splineVisibilityChanged (bool visible )
