Detailed Description

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

This type manages the spline specific visual elements.

Property Documentation

baseColor : color

Sets the base color of the series.

See also colorStyle and GraphsTheme.seriesColors.


baseGradient : Gradient

Sets the base gradient of the series.

See also colorStyle and GraphsTheme.seriesGradients.


colorStyle : GraphsTheme.ColorStyle

Sets the color style for the series.

See also GraphsTheme.ColorStyle.


itemLabel : string [read-only]

The formatted item label. If there is no selected item or the selected item is not visible, returns an empty string.

See also itemLabelFormat.


itemLabelFormat : string

The label format for data items in this series. This format is used for single item labels, for example, when an item is selected. How the format is interpreted depends on series type: Bar3DSeries, Scatter3DSeries, Surface3DSeries.


itemLabelVisible : bool

If true, item labels are drawn as floating labels in the graph. Otherwise, item labels are not drawn. To show the item label in an external control, this property is set to false. Defaults to true.

See also itemLabelFormat and itemLabel.


mesh : Abstract3DSeries.Mesh

Sets the mesh of the items in the series, or the selection pointer in case of Surface3DSeries. If the mesh is Abstract3DSeries.Mesh.UserDefined, then the userDefinedMesh property must also be set for items to render properly. The default value depends on the graph type.

See also QAbstract3DSeries::Mesh.


meshRotation : quaternion

Sets the mesh rotation that is applied to all items of the series. The rotation should be a normalized quaternion. For those series types that support item specific rotation, the rotations are multiplied together. Bar3DSeries ignores any rotation that is not around the y-axis. Surface3DSeries applies the rotation only to the selection pointer. Defaults to no rotation.


meshSmooth : bool

If true, smooth versions of predefined meshes set via the mesh property are used. This property does not affect custom meshes used when the mesh is set to Abstract3DSeries.Mesh.UserDefined. Defaults to false.


multiHighlightColor : color

Sets the multiple item highlight color of the series.

See also colorStyle and GraphsTheme.multiHighlightColor.


multiHighlightGradient : Gradient

Sets the multiple item highlight gradient of the series.

See also colorStyle and GraphsTheme.multiHighlightGradient.


name : string

The series name. It can be used in item label format with the tag @seriesName.

See also itemLabelFormat.


singleHighlightColor : color

Sets the single item highlight color of the series.

See also colorStyle and GraphsTheme.singleHighlightColor.


singleHighlightGradient : Gradient

Sets the single item highlight gradient of the series.

See also colorStyle and GraphsTheme.singleHighlightGradient.


splineColor : color

The color of the spline.


splineKnotting : float

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.


splineLooping : float

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


splineTension : float

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


splineVisible : bool

Visibility of the spline. The default value is true.


type : Abstract3DSeries.SeriesType [read-only]

The type of the series. One of the QAbstract3DSeries::SeriesType values.


userDefinedMesh : string

Sets the filename for a user defined custom mesh for objects that is used when mesh is Abstract3DSeries.Mesh.UserDefined.

Note: The file needs to be in the QtQuick3D mesh format. Use the balsam conversion tool to create a mesh from other 3D model formats.


visible : bool

Sets the visibility of the series. If false, the series is not rendered.
