详细描述

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.

特性文档编制

autoAdjustRange : bool

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

访问函数：

bool isAutoAdjustRange () const
void setAutoAdjustRange (bool autoAdjust )

通知程序信号：

void autoAdjustRangeChanged (bool autoAdjust )

另请参阅 setRange (), setMin ()，和 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.

访问函数：

float labelAutoRotation () const
void setLabelAutoRotation (float angle )

通知程序信号：

void labelAutoRotationChanged (float angle )

labels : QStringList

此特性保持轴的标签。

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

访问函数：

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

通知程序信号：

void labelsChanged ()

max : float

此特性保持轴的最大值。

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.

访问函数：

float max () const
void setMax (float max )

通知程序信号：

void maxChanged (float value )

min : float

此特性保持轴的最小值。

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.

访问函数：

float min () const
void setMin (float min )

通知程序信号：

void minChanged (float value )

orientation : const AxisOrientation

此特性保持轴的取向。

The value is one of AxisOrientation 值。

访问函数：

QAbstract3DAxis::AxisOrientation orientation () const

通知程序信号：

void orientationChanged (QAbstract3DAxis::AxisOrientation orientation )

title : QString

此特性保持轴的标题。

访问函数：

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

通知程序信号：

void titleChanged (const QString & newTitle )

另请参阅 titleVisible and titleFixed .

titleFixed : bool

此特性保持轴标题的旋转。

若 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 特性值为 0。默认值为 true .

访问函数：

bool isTitleFixed () const
void setTitleFixed (bool fixed )

通知程序信号：

void titleFixedChanged (bool fixed )

另请参阅 labelAutoRotation , title ，和 titleVisible .

titleVisible : bool

此特性保持轴标题在首要图形视图中是否可见。

默认值为 false .

访问函数：

bool isTitleVisible () const
void setTitleVisible (bool visible )

通知程序信号：

void titleVisibilityChanged (bool visible )

另请参阅 title and titleFixed .

type : const AxisType

此特性保持轴的类型。

The value is one of AxisType 值。

访问函数：

QAbstract3DAxis::AxisType type () const

成员函数文档编制

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

Emits the minimum and maximum values of the range, min and max ，当范围改变时。

[虚拟] QAbstract3DAxis:: ~QAbstract3DAxis ()

销毁 QAbstract3DAxis .

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.
