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:

QAbstract3DSeries::Mesh mesh() const
void setMesh(QAbstract3DSeries::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:

QAbstract3DSeries::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.
