Detailed Description

This class specifies the enumerations, properties, and functions shared by graph axes. It should not be used directly, but one of its subclasses should be used instead.

Property Documentation

autoAdjustRange : bool

This property holds whether the axis will automatically adjust the range so that all data fits in it.

Access functions:

bool isAutoAdjustRange() const
void setAutoAdjustRange(bool autoAdjust)

Notifier signal:

void autoAdjustRangeChanged(bool autoAdjust)

See also setRange(), setMin(), and setMax().

labelAutoRotation : float

This property holds the maximum angle the labels can autorotate when the camera angle changes.

The angle can be between 0 and 90, inclusive. The default value is 0. If the value is 0, axis labels do not automatically rotate. If the value is greater than zero, labels attempt to orient themselves toward the camera, up to the specified angle.

Access functions:

float labelAutoRotation() const
void setLabelAutoRotation(float angle)

Notifier signal:

void labelAutoRotationChanged(float angle)

labels : QStringList

This property holds the labels for the axis.

Note: Setting this property for QValue3DAxis does nothing, as it generates labels automatically.

Access functions:

QStringList labels() const
void setLabels(const QStringList &labels)

Notifier signal:

void labelsChanged()

max : float

This property holds the maximum value on the axis.

When setting this property, the minimum value is adjusted if necessary, to ensure that the range remains valid.

Note: For QCategory3DAxis, specifies the index of the last row or column to show.

Access functions:

float max() const
void setMax(float max)

Notifier signal:

void maxChanged(float value)

min : float

This property holds the minimum value on the axis.

When setting this property, the maximum value is adjusted if necessary, to ensure that the range remains valid.

Note: For QCategory3DAxis, specifies the index of the first row or column to show.

Access functions:

float min() const
void setMin(float min)

Notifier signal:

void minChanged(float value)

[read-only] orientation : const AxisOrientation

This property holds the orientation of the axis.

The value is one of AxisOrientation values.

Access functions:

QAbstract3DAxis::AxisOrientation orientation() const

Notifier signal:

void orientationChanged(QAbstract3DAxis::AxisOrientation orientation)

title : QString

This property holds the title for the axis.

Access functions:

QString title() const
void setTitle(const QString &title)

Notifier signal:

void titleChanged(const QString &newTitle)

See also titleVisible and titleFixed.

titleFixed : bool

This property holds the rotation of the axis titles.

If true, axis titles in the primary graph view will be rotated towards the camera similarly to the axis labels. If false, axis titles are only rotated around their axis but are not otherwise oriented towards the camera. This property does not have any effect if the labelAutoRotation property value is zero. Default value is true.

Access functions:

bool isTitleFixed() const
void setTitleFixed(bool fixed)

Notifier signal:

void titleFixedChanged(bool fixed)

See also labelAutoRotation, title, and titleVisible.

titleVisible : bool

This property holds whether the axis title is visible in the primary graph view.

The default value is false.

Access functions:

bool isTitleVisible() const
void setTitleVisible(bool visible)

Notifier signal:

void titleVisibilityChanged(bool visible)

See also title and titleFixed.

[read-only] type : const AxisType

This property holds the type of the axis.

The value is one of AxisType values.

Access functions:

QAbstract3DAxis::AxisType type() const

Member Function Documentation

[virtual] QAbstract3DAxis::~QAbstract3DAxis()

Destroys QAbstract3DAxis.

[signal] void QAbstract3DAxis::rangeChanged(float min, float max)

Emits the minimum and maximum values of the range, min and max, when the range changes.

void QAbstract3DAxis::setRange(float min, float max)

Sets the value range of the axis from min to max. When setting the range, the maximum value is adjusted if necessary, to ensure that the range remains valid.

Note: For QCategory3DAxis, specifies the index range of rows or columns to show.
