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.

Member Type Documentation
enum QAbstract3DAxis::AxisOrientation

QAbstract3DAxis::AxisOrientationZ | 4 |
enum QAbstract3DAxis::AxisType

QAbstract3DAxis::AxisTypeCategory | 1 |
QAbstract3DAxis::AxisTypeValue | 2 |
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 noexcept] 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.
