Detailed Description
This abstract class serves as a base class for the following subtypes: Bar3DSeries, Scatter3DSeries, and Surface3DSeries.
For more information, see Qt Graphs Data Handling with 3D.
Property Documentation
baseColor : color
The base color of the series.
See also colorStyle and GraphsTheme.seriesColors.
baseGradient : Gradient
The base gradient of the series.
See also colorStyle.
colorStyle : enumeration
The color style for the series.
| Constant | Description |
|---|---|
GraphsTheme.ColorStyle.Uniform | Objects are rendered in a single color. The color used is specified in seriesColors, singleHighlightColor and multiHighlightColor properties. |
GraphsTheme.ColorStyle.ObjectGradient | Objects are colored using a full gradient for each object regardless of object height. The gradient used is specified in seriesGradients, singleHighlightGradient and multiHighlightGradient properties. |
GraphsTheme.ColorStyle.RangeGradient | Objects are colored using a portion of the full gradient determined by the object's height and its position on the Y-axis. The gradient used is specified in seriesGradients, singleHighlightGradient and multiHighlightGradient properties. |
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.
See also Bar3DSeries, Scatter3DSeries, and 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.
lightingMode : enumeration [since 6.10]
The lighting mode of the items in the series. The default value is QAbstract3DSeries::LightingMode::Shaded
| Constant | Description |
|---|---|
Abstract3DSeries.LightingMode.Shaded | Graphs respond to real time lighting |
Abstract3DSeries.LightingMode.Unshaded | Graphs do not respond to real time lighting |
This property was introduced in Qt 6.10.
See also QAbstract3DSeries::LightingMode.
mesh : enumeration
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.
| Constant | Description |
|---|---|
Abstract3DSeries.Mesh.UserDefined | User defined mesh, set via QAbstract3DSeries::userDefinedMesh property. |
Abstract3DSeries.Mesh.Bar | Basic rectangular bar. |
Abstract3DSeries.Mesh.Cube | Basic cube. |
Abstract3DSeries.Mesh.Pyramid | Four-sided pyramid. |
Abstract3DSeries.Mesh.Cone | Basic cone. |
Abstract3DSeries.Mesh.Cylinder | Basic cylinder. |
Abstract3DSeries.Mesh.BevelBar | Slightly beveled (rounded) rectangular bar. |
Abstract3DSeries.Mesh.BevelCube | Slightly beveled (rounded) cube. |
Abstract3DSeries.Mesh.Sphere | Sphere. |
Abstract3DSeries.Mesh.Minimal | The minimal 3D mesh: a triangular pyramid. Usable only with Q3DScatterWidgetItem. |
Abstract3DSeries.Mesh.Arrow | Arrow pointing upwards. |
Abstract3DSeries.Mesh.Point | 2D point. Usable only with Q3DScatterWidgetItem. Shadows do not affect this style. Color style QGraphsTheme::ColorStyle::ObjectGradient is not supported by this style. |
See also QAbstract3DSeries::Mesh.
meshRotation : quaternion
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
The multiple item highlight color of the series.
See also colorStyle and GraphsTheme.multiHighlightColor.
multiHighlightGradient : Gradient
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
The single item highlight color of the series.
See also colorStyle and GraphsTheme.singleHighlightColor.
singleHighlightGradient : Gradient
The single item highlight gradient of the series.
See also colorStyle and GraphsTheme.singleHighlightGradient.
type : enumeration [read-only]
The type of the series. One of the QAbstract3DSeries::SeriesType values.
| Constant | Description |
|---|---|
Abstract3DSeries.SeriesType.None | No series type. |
Abstract3DSeries.SeriesType.Bar | Series type for Q3DBarsWidgetItem. |
Abstract3DSeries.SeriesType.Scatter | Series type for Q3DScatterWidgetItem. |
Abstract3DSeries.SeriesType.Surface | Series type for Q3DSurfaceWidgetItem. |
userDefinedMesh : string
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
The visibility of the series. If false, the series is not rendered.
