详细描述

An area graph is used to draw an area composed by points. The points are defined by two series: upperSeries and lowerSeries . The area between the series is drawn as a graph. If only the upperSeries is defined, the area is then between the bottom of the graph and the upper series.

borderColor : QColor

This property holds the border color of the area. The default value is Qt::transparent , meaning the border color is defined by the theme.

访问函数：

QColor	borderColor () const
void	setBorderColor (QColor newBorderColor )

通知程序信号：

void	borderColorChanged (QColor newBorderColor )

borderWidth : qreal

This property holds the width of the line that encloses the area. The default value is -1 , meaning the border width is defined by the theme.

访问函数：

qreal	borderWidth () const
void	setBorderWidth (qreal newBorderWidth )

通知程序信号：

void	borderWidthChanged ()

color : QColor

This property holds the fill color of the area. The default value is Qt::transparent , meaning the color is defined by the theme.

访问函数：

QColor	color () const
void	setColor (QColor newColor )

通知程序信号：

void	colorChanged (QColor newColor )

lowerSeries : QXYSeries *

Sets the lower boundary of the area. If this is null, the graph bottom is considered the lower bound.

访问函数：

QXYSeries *	lowerSeries () const
void	setLowerSeries (QXYSeries * newLowerSeries )

通知程序信号：

void	lowerSeriesChanged ()

selected : bool

Sets this area as selected. The default value is false .

访问函数：

bool	isSelected () const
void	setSelected (bool newSelected )

通知程序信号：

void	selectedChanged ()

selectedBorderColor : QColor

This property holds the border color of the area when selected. The default value is Qt::transparent , meaning the selected border color is defined by the theme.

访问函数：

QColor	selectedBorderColor () const
void	setSelectedBorderColor (QColor newSelectedBorderColor )

通知程序信号：

void	selectedBorderColorChanged (QColor newSelectedBorderColor )

selectedColor : QColor

This property holds the fill color of the area when selected. The default value is Qt::transparent , meaning the selected color is defined by the theme.

访问函数：

QColor	selectedColor () const
void	setSelectedColor (QColor newColor )

通知程序信号：

void	selectedColorChanged (QColor newSelectedColor )

upperSeries : QXYSeries *

Sets the upper boundary of the area. No area is drawn if this is null.

访问函数：

QXYSeries *	upperSeries () const
void	setUpperSeries (QXYSeries * newUpperSeries )

通知程序信号：

void	upperSeriesChanged ()
