Detailed Description

This type manages the series specific visual elements, as well as the series data (via a data proxy).

Surface3DSeries supports the following format tags for itemLabelFormat:

@xTitleTitle from x-axis
@yTitleTitle from y-axis
@zTitleTitle from z-axis
@xLabelItem value formatted using the format of the x-axis. For more information, see labelFormat.
@yLabelItem value formatted using the format of the y-axis. For more information, see labelFormat.
@zLabelItem value formatted using the format of the z-axis. For more information, see labelFormat.
@seriesNameName of the series

For a more complete description, see QSurface3DSeries.

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.


dataArray : SurfaceDataArray

Holds the reference of the data array.

dataArrayChanged signal is emitted when data array is set, unless newDataArray is identical to the previous one.

Note: Before doing anything regarding the dataArray, a series must be created for the relevant proxy.


dataProxy : SurfaceDataProxy

The active data proxy. The series assumes ownership of any proxy set to it and deletes any previously set proxy when a new one is added. The proxy cannot be null or set to another series.


drawMode : DrawFlag

Sets the drawing mode to one of Surface3DSeries.DrawFlag. Clearing all flags is not allowed.


flatShadingSupported : bool [read-only]

Indicates whether flat shading for surfaces is supported by the current system. It requires at least GLSL version 1.2 with GL_EXT_gpu_shader4 extension.

Note: This read-only property is set to its correct value after the first render pass. Until then it is always true.


invalidSelectionPosition : point [read-only]

A constant property providing an invalid selection position. This position is assigned to the selectedPoint property to clear the selection from this series.

See also GraphsItem3D::clearSelection().


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.


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.


selectedPoint : point

Sets the surface grid point in the position specified by a row and a column in the data array of the series as selected. Only one point can be selected at a time.

To clear the selection from this series, assign invalidSelectionPosition as the position. If this series is added to a graph, the graph can adjust the selection according to user interaction or if it becomes invalid.

Removing rows from or inserting rows into the series before the row of the selected point will adjust the selection so that the same point will stay selected.

See also GraphsItem3D::clearSelection().


shading : Shading

Sets surface flat shading to visible. It is preset to Surface3DSeries.Shading.Flat by default. When disabled, the normals on the surface are interpolated making the edges look round. When visible, the normals are kept the same on a triangle making the color of the triangle solid. This makes the data more readable from the model.

Note: Flat shaded surfaces require at least GLSL version 1.2 with GL_EXT_gpu_shader4 extension. The value of the flatShadingSupported property indicates whether flat shading is supported at runtime.


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.


textureFile : string

The texture file name for the surface texture. To clear the texture, an empty file name is set.


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.


wireframeColor : color

The color used to draw the gridlines of the surface wireframe.
