PySide6.QtGraphs.QSpline3DSeries

class QSpline3DSeries

The QSpline3DSeries class represents a data series as a spline.

Details

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.

Added in version 6.9.

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property splineColorᅟ: QColor

This property holds The color of the spline..

Access functions:

• splineColor()

• setSplineColor()

• Signal splineColorChanged()

property splineKnottingᅟ: float

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.

The value must be between 0.0 and 1.0. The default value is 0.5.

Access functions:

• splineKnotting()

• setSplineKnotting()

• Signal splineKnottingChanged()

property splineLoopingᅟ: bool

This property 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.

The default value is false

Access functions:

• isSplineLooping()

• setSplineLooping()

• Signal splineLoopingChanged()

property splineResolutionᅟ: 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. The default value is 10.

Access functions:

• splineResolution()

• setSplineResolution()

• Signal splineResolutionChanged()

property splineTensionᅟ: float

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 Must be between 0.0 and 1.0 The default value is 0.0

Access functions:

• splineTension()

• setSplineTension()

• Signal splineTensionChanged()

property splineVisibleᅟ: bool

This property holds Visibility of the spline..

Visibility of the spline. The default value is true.

Access functions:

• isSplineVisible()

• setSplineVisible()

• Signal splineVisibilityChanged()

__init__([parent=None])

Parameters:
