特性文档编制

hoverable : bool

Controls if the series is hoverable.

Controls if the series can be hovered with mouse/touch. By default, hoverable 被设为 false .

注意： In 6.8, QPieSeries does not emit signals related to hovering.

访问函数：

bool	isHoverable () const
void	setHoverable (bool newHoverable )

通知程序信号：

void	hoverableChanged ()

[read-only] legendData : const QList < QLegendData >

Contains information needed to create a legend marker for a data set in a graph.

访问函数：

const QList<QLegendData>

legendData () const

通知程序信号：

void	legendDataChanged ()

另请参阅 QLegendData .

name : QString

This property holds the name of the series.

The name is displayed in the legend for the series and it supports HTML formatting.

访问函数：

QString	名称 () const
void	setName (const QString & name )

通知程序信号：

void	nameChanged ()

opacity : qreal

This property holds the opacity of the series.

By default, the opacity is 1.0. The valid values range from 0.0 (transparent) to 1.0 (opaque).

访问函数：

qreal	opacity () const
void	setOpacity (qreal opacity )

通知程序信号：

void	opacityChanged ()

selectable : bool

Controls if the series is selectable.

Controls if the series can be selected with mouse/touch. By default, selectable 被设为 false .

访问函数：

bool	isSelectable () const
void	setSelectable (bool selectable )

通知程序信号：

void	selectableChanged ()

[read-only] type : const SeriesType

This property holds the type of the series.

访问函数：

virtual QAbstractSeries::SeriesType

type () const = 0

valuesMultiplier : qreal

Controls the series values effective visible value.

This variable can be used for animating the series values so they scale from 0 to actual value size. By default, the valuesMultiplier is 1.0. The valid values range from 0.0 (height 0) to 1.0 (full value).

访问函数：

qreal	valuesMultiplier () const
void	setValuesMultiplier (qreal valuesMultiplier )

通知程序信号：

void	valuesMultiplierChanged ()

visible : bool

Visibility of the series.

The visibility used for this series. By default, visible 被设为 true .

访问函数：

bool	isVisible () const
void	setVisible (bool visible = true)

通知程序信号：

void	visibleChanged ()

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

Virtual destructor for the graph series.

void QAbstractSeries:: hide ()

Sets the visibility of the series to false .

另请参阅 setVisible () 和 isVisible ().

[signal] void QAbstractSeries:: hover (const QString & seriesName , QPointF position , QPointF value )

This signal is emitted when the series hovering changes. The name of the series is in seriesName , the mouse/touch position in position , and the series value in value .

注意： 此信号才被发射当 hoverable 被设为 true。

[signal] void QAbstractSeries:: hoverEnter (const QString & seriesName , QPointF position , QPointF value )

This signal is emitted when the series hovering starts. The name of the series is in seriesName , the mouse/touch position in position , and the series value in value .

注意： 此信号才被发射当 hoverable 被设为 true。

[signal] void QAbstractSeries:: hoverExit (const QString & seriesName , QPointF position )

This signal is emitted when the series hovering ends. The name of the series is in seriesName , and the mouse/touch position in position .

注意： 此信号才被发射当 hoverable 被设为 true。

void QAbstractSeries:: show ()

Sets the visibility of the series to true .

另请参阅 setVisible () 和 isVisible ().
