## Property Documentation

### baseColor : QColor

This property holds the base color of the series.

Access functions:

QColor | baseColor() const
void | setBaseColor(const QColor &color)

Notifier signal:

void | baseColorChanged(const QColor &color)

See also colorStyle and Q3DTheme::baseColors.

### baseGradient : QLinearGradient

This property holds the base gradient of the series.

Access functions:

QLinearGradient | baseGradient() const
void | setBaseGradient(const QLinearGradient &gradient)

Notifier signal:

void | baseGradientChanged(const QLinearGradient &gradient)

See also colorStyle and Q3DTheme::baseGradients.

### colorStyle : QtDataVisualization::Q3DTheme::ColorStyle

This property holds the color style for the series.

Access functions:

Q3DTheme::ColorStyle | colorStyle() const
void | setColorStyle(Q3DTheme::ColorStyle style)

Notifier signal:

void | colorStyleChanged(Q3DTheme::ColorStyle style)

See also Q3DTheme::ColorStyle.

### itemLabel : const QString

This property holds the formatted item label.

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

This property was introduced in QtDataVisualization 1.1.

Access functions:

QString | itemLabel() const

Notifier signal:

void | itemLabelChanged(const QString &label)

See also itemLabelFormat.

### itemLabelFormat : QString

This property holds 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: QBar3DSeries, QScatter3DSeries, QSurface3DSeries.

Access functions:

QString | itemLabelFormat() const
void | setItemLabelFormat(const QString &format)

Notifier signal:

void | itemLabelFormatChanged(const QString &format)

### itemLabelVisible : bool

This property holds the visibility of item labels in the graph.

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`.

This property was introduced in QtDataVisualization 1.1.

Access functions:

bool | isItemLabelVisible() const
void | setItemLabelVisible(bool visible)

Notifier signal:

void | itemLabelVisibilityChanged(bool visible)

See also itemLabelFormat and itemLabel.

### mesh : Mesh

This property holds the mesh of the items in the series.

For QSurface3DSeries, this property holds the selection pointer.

If the mesh is MeshUserDefined, then the userDefinedMesh property must also be set for items to render properly. The default value depends on the graph type.

Access functions:

Mesh | mesh() const
void | setMesh(Mesh mesh)

Notifier signal:

void | meshChanged(QAbstract3DSeries::Mesh mesh)

### meshRotation : QQuaternion

This property holds the mesh rotation that is applied to all items of the series.

The rotation should be a normalized QQuaternion. For those series types that support item specific rotation, the rotations are multiplied together. QBar3DSeries ignores any rotation that is not around the y-axis. QSurface3DSeries applies the rotation only to the selection pointer. Defaults to no rotation.

Access functions:

QQuaternion | meshRotation() const
void | setMeshRotation(const QQuaternion &rotation)

Notifier signal:

void | meshRotationChanged(const QQuaternion &rotation)

### meshSmooth : bool

This property holds whether smooth versions of predefined meshes are used.

If `true`, smooth versions set via the mesh property are used. This property does not affect custom meshes used when the mesh is set to MeshUserDefined. Defaults to `false`.

Access functions:

bool | isMeshSmooth() const
void | setMeshSmooth(bool enable)

Notifier signal:

void | meshSmoothChanged(bool enabled)

### multiHighlightColor : QColor

This property holds the multiple item highlight color of the series.

Access functions:

QColor | multiHighlightColor() const
void | setMultiHighlightColor(const QColor &color)

Notifier signal:

void | multiHighlightColorChanged(const QColor &color)

See also colorStyle and Q3DTheme::multiHighlightColor.

### multiHighlightGradient : QLinearGradient

This property holds the multiple item highlight gradient of the series.

Access functions:

QLinearGradient | multiHighlightGradient() const
void | setMultiHighlightGradient(const QLinearGradient &gradient)

Notifier signal:

void | multiHighlightGradientChanged(const QLinearGradient &gradient)

See also colorStyle and Q3DTheme::multiHighlightGradient.

### name : QString

This property holds the series name.

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

Access functions:

QString | name() const
void | setName(const QString &name)

Notifier signal:

void | nameChanged(const QString &name)

See also itemLabelFormat.

### singleHighlightColor : QColor

This property holds the single item highlight color of the series.

Access functions:

QColor | singleHighlightColor() const
void | setSingleHighlightColor(const QColor &color)

Notifier signal:

void | singleHighlightColorChanged(const QColor &color)

See also colorStyle and Q3DTheme::singleHighlightColor.

### singleHighlightGradient : QLinearGradient

This property holds the single item highlight gradient of the series.

Access functions:

QLinearGradient | singleHighlightGradient() const
void | setSingleHighlightGradient(const QLinearGradient &gradient)

Notifier signal:

void | singleHighlightGradientChanged(const QLinearGradient &gradient)

See also colorStyle and Q3DTheme::singleHighlightGradient.

### type : const SeriesType

This property holds the type of the series.

Access functions:

SeriesType | type() const

### userDefinedMesh : QString

This property holds the filename for a user defined custom mesh for objects.

The custom mesh is used when mesh is MeshUserDefined.

Note: The file needs to be in the Wavefront OBJ format and include vertices, normals, and UVs. It also needs to be in triangles.

Access functions:

QString | userDefinedMesh() const
void | setUserDefinedMesh(const QString &fileName)

Notifier signal:

void | userDefinedMeshChanged(const QString &fileName)

### visible : bool

This property holds the visibility of the series.

If this property is `false`, the series is not rendered. Defaults to `true`.

Access functions:

bool | isVisible() const
void | setVisible(bool visible)

Notifier signal:

void | visibilityChanged(bool visible)

### void QAbstract3DSeries::setMeshAxisAndAngle(const QVector3D &axis, float angle)

A convenience function to construct a mesh rotation quaternion from axis and angle.

Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.
