Bar3DSeries QML Type

The optional column labels for the array. Indexes in this array match column indexes in rows. If the list is shorter than the longest row, all columns will not get labels.

dataArray : BarDataArray

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 : BarDataProxy

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.

invalidSelectionPosition : point

A constant property providing an invalid position for selection. This position is set to the selectedBar 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: 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.

meshAngle : real

A convenience property for defining the series rotation angle in degrees.

Note: When reading this property, it is calculated from the Abstract3DSeries.meshRotation value using floating point precision and always returns a value from zero to 360 degrees.

See also Abstract3DSeries.meshRotation.

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.

rowColors : list<Color>

This property can be used to draw the rows of the series in different colors. The GraphsTheme.colorStyle must be set to Uniform to use this property.

Note: If the property is set and the theme is changed, the rowColors list is not cleared automatically.

rowLabels : list

The optional row labels for the array. Indexes in this array match the row indexes in the data array. If the list is shorter than the number of rows, all rows will not get labels.

selectedBar : point

The bar in the series that is selected.

The position of the selected bar is specified as a row and column in the data array of the series.

Only one bar can be selected at a time.

To clear the selection from this series, set 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. Selecting a bar on another added series will also clear the selection.

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

See also GraphsItem3D.clearSelection().

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.

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 Wavefront OBJ format and include vertices, normals, and UVs. It also needs to be in triangles.

visible : bool

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