詳細描述

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.

autoAdjustRange : bool

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

訪問函數：

bool	isAutoAdjustRange () const
void	setAutoAdjustRange (bool autoAdjust )

通知程序信號：

void	autoAdjustRangeChanged (bool autoAdjust )

另請參閱 setRange (), setMin ()，和 setMax ().

labelAutoAngle : 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.

訪問函數：

float	labelAutoAngle () const
void	setLabelAutoAngle (float degree )

通知程序信號：

void	labelAutoAngleChanged (float angle )

[since 6.9] labelSize : qreal

Size of the label

The size of the label. The default for this value is 1.0 .

該特性在 Qt 6.9 引入。

訪問函數：

qreal	labelSize () const
void	setLabelSize (qreal size )

通知程序信號：

void	labelSizeChanged (qreal size )

另請參閱 scaleLabelsByCount .

labels : QStringList

此特性保持軸的標簽。

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

訪問函數：

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

通知程序信號：

void	labelsChanged ()

labelsVisible : bool

This property holds whether the axis labels are visible in the primary graph view.

默認值為 true .

訪問函數：

bool	labelsVisible () const
void	setLabelsVisible (bool visible )

通知程序信號：

void	labelVisibleChanged (bool visible )

max : float

此特性保持軸的最大值。

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

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

訪問函數：

float	max () const
void	setMax (float max )

通知程序信號：

void	maxChanged (float value )

min : float

此特性保持軸的最小值。

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

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

訪問函數：

float	min () const
void	setMin (float min )

通知程序信號：

void	minChanged (float value )

[read-only] orientation : const QAbstract3DAxis::AxisOrientation

此特性保持軸的取嚮。

The value is one of AxisOrientation 值。

訪問函數：

QAbstract3DAxis::AxisOrientation

orientation () const

通知程序信號：

void	orientationChanged (QAbstract3DAxis::AxisOrientation orientation )

[since 6.9] scaleLabelsByCount : bool

This property holds whether the labels will automatically adjust their size based on the total amount of labels

該特性在 Qt 6.9 引入。

訪問函數：

bool	isScaleLabelsByCount () const
void	setScaleLabelsByCount (bool adjust )

通知程序信號：

void	scaleLabelsByCountChanged (bool adjust )

另請參閱 labelSize ().

title : QString

此特性保持軸的標題。

訪問函數：

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

通知程序信號：

void	titleChanged (const QString & newTitle )

另請參閱 titleVisible and titleFixed .

titleFixed : bool

此特性保持軸標題的鏇轉。

若 false , axis titles in the primary graph view will be rotated towards the camera similarly to the axis labels. If true , 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 labelAutoAngle 特性值為 0。默認值為 true .

訪問函數：

bool	isTitleFixed () const
void	setTitleFixed (bool fixed )

通知程序信號：

void	titleFixedChanged (bool fixed )

另請參閱 labelAutoAngle , title ，和 titleVisible .

titleOffset : float

The position of the axis title on the axis. The value must be between -1.0f and 1.0f

訪問函數：

float	titleOffset () const
void	setTitleOffset (float offset )

通知程序信號：

void	titleOffsetChanged (float offset )

另請參閱 title and titleFixed .

titleVisible : bool

此特性保持軸標題在首要圖形視圖中是否可見。

默認值為 false .

訪問函數：

bool	isTitleVisible () const
void	setTitleVisible (bool visible )

通知程序信號：

void	titleVisibleChanged (bool visible )

另請參閱 title and titleFixed .

[read-only] type : const QAbstract3DAxis::AxisType

此特性保持軸的類型。

The value is one of AxisType 值。

訪問函數：

QAbstract3DAxis::AxisType

type () const

成員函數文檔編製

[override virtual noexcept] QAbstract3DAxis:: ~QAbstract3DAxis ()

銷毀 QAbstract3DAxis .

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

Emits the minimum and maximum values of the range, min and max ，當範圍改變時。

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.

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