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 .

访问函数：

bool	hoverable () const
void	setHoverable (bool newHoverable )

通知程序信号：

void	hoverableChanged ()

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	name () 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	selectable () const
void	setSelectable (bool selectable )

通知程序信号：

void	selectableChanged ()

theme : QSeriesTheme *

This property holds the theme of the series.

The theme used for this series.

访问函数：

QSeriesTheme *	theme () const
void	setTheme (QSeriesTheme * newTheme )

通知程序信号：

void	themeChanged ()

`[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 ()

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

Virtual destructor for the graph series.

bool QAbstractSeries:: attachAxis ( QAbstractAxis * axis )

附加轴的指定是通过 axis 到系列。

返回 true 若轴附加成功， false 否则。

注意： If multiple axes of the same orientation are attached to the same series, they will have the same minimum and maximum values.

QList < QAbstractAxis *> QAbstractSeries:: attachedAxes ()

Returns the list of axes attached to the series. Usually, an x-axis and a y-axis are attached to a series, except for QPieSeries, which does not have any axes attached.

另请参阅 attachAxis () 和 detachAxis ().

bool QAbstractSeries:: detachAxis ( QAbstractAxis * axis )

Detaches the axis specified by axis from the series.

返回 true if the axis was detached successfully, false 否则。

QGraphsView *QAbstractSeries:: graph () const

Returns the graph that the series belongs to.

Set automatically when the series is added to the graph, and unset when the series is removed from the graph.

void QAbstractSeries:: hide ()

Sets the visibility of the series to false .

另请参阅 setVisible () 和 isVisible ().

`[signal]` void QAbstractSeries:: hover ( 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 is set to true.

`[signal]` void QAbstractSeries:: hoverEnter ( 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 is set to true.

`[signal]` void QAbstractSeries:: hoverExit ( 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 is set to true.

`[signal]` void QAbstractSeries:: hoverableChanged ()

This signal is emitted when the series hoverable changes.

注意： 通知程序信号对于特性 hoverable .

`[signal]` void QAbstractSeries:: nameChanged ()

This signal is emitted when the series name changes.

注意： 通知程序信号对于特性 name .

`[signal]` void QAbstractSeries:: opacityChanged ()

This signal is emitted when the opacity of the series changes.

注意： 通知程序信号对于特性 opacity .

`[signal]` void QAbstractSeries:: selectableChanged ()

This signal is emitted when the series selectable changes.

注意： 通知程序信号对于特性 selectable .

void QAbstractSeries:: show ()

Sets the visibility of the series to true .

另请参阅 setVisible () 和 isVisible ().

`[signal]` void QAbstractSeries:: themeChanged ()

This signal is emitted when the series theme changes.

注意： 通知程序信号对于特性 theme .

`[signal]` void QAbstractSeries:: valuesMultiplierChanged ()

此信号发射当 valuesMultiplier of the series changes.

注意： 通知程序信号对于特性 valuesMultiplier .

`[signal]` void QAbstractSeries:: visibleChanged ()

This signal is emitted when the series visibility changes.

注意： 通知程序信号对于特性 visible .
