公共函数

QBarSeries (QObject * parent = nullptr)
virtual ~QBarSeries ()
QAbstractAxis * axisX ()
QAbstractAxis * axisY ()
void setAxisX (QAbstractAxis * axis )
void setAxisY (QAbstractAxis * axis )

重实现公共函数

virtual QAbstractSeries::SeriesType type () const override

信号

void axisXChanged (QAbstractAxis * axis )
void axisYChanged (QAbstractAxis * axis )

详细描述

此类将数据绘制为按类别分组的一系列垂直条形,采用把各类别来自每条形集的每一条形添加到系列。

特性文档编制

axisX : QAbstractAxis *

X-axis of the series.

The x-axis used for the series. This should be QBarCategoryAxis .

访问函数:

QAbstractAxis * axisX ()
void setAxisX (QAbstractAxis * axis )

通知程序信号:

void axisXChanged (QAbstractAxis * axis )

axisY : QAbstractAxis *

Y-axis of the series.

The y-axis used for the series. This should be QValueAxis .

访问函数:

QAbstractAxis * axisY ()
void setAxisY (QAbstractAxis * axis )

通知程序信号:

void axisYChanged (QAbstractAxis * axis )

[explicit] QBarSeries:: QBarSeries ( QObject * parent = nullptr)

构造的空条形系列是 QObject 和子级对于 parent .

[virtual noexcept] QBarSeries:: ~QBarSeries ()

Removes the bar series from the graph.

[override virtual] QAbstractSeries::SeriesType QBarSeries:: type () const

重实现访问函数为特性: QAbstractSeries::type .

返回条形系列。
