詳細描述

The scatter data is displayed as a collection of points on the chart. For each point, two values are specified that determine its position on the horizontal axis and the vertical axis.

The following code snippet illustrates how to create a basic scatter chart:

QScatterSeries* series = new QScatterSeries();
series->append(0, 6);
series->append(2, 4);
...
chart->addSeries(series);

borderColor : QColor

This property holds the color used to draw the marker borders.

This is a convenience property for modifying the color of the pen.

訪問函數：

QColor	borderColor () const
void	setBorderColor (const QColor & color )

通知程序信號：

void	borderColorChanged (QColor color )

另請參閱 QScatterSeries::pen ().

brush : QBrush

This property holds the brush used to draw the scatter series markers.

The brush can be an image that can be created using QPainterPath ，例如。

訪問函數：

QBrush	brush () const
virtual void	setBrush (const QBrush & brush ) override

color : QColor

This property holds the color used to fill the series markers.

This is a convenience property for modifying the color of the brush.

訪問函數：

virtual QColor	color () const override
virtual void	setColor (const QColor & color ) override

通知程序信號：

void	colorChanged (QColor color )

另請參閱 QScatterSeries::brush ().

markerShape : MarkerShape

This property holds the shape of the marker used to render the points in the series.

The default shape is MarkerShapeCircle .

訪問函數：

void	setMarkerShape (QScatterSeries::MarkerShape shape )

通知程序信號：

void	markerShapeChanged (QScatterSeries::MarkerShape shape )

另請參閱 MarkerShape .

markerSize : qreal

This property holds the size of the marker used to render the points in the series.

The default size is 15.0.

QScatterSeries:: QScatterSeries ( QObject * parent = nullptr)

Constructs a series object that is a child of parent .

[signal] void QScatterSeries:: borderColorChanged ( QColor color )

This signal is emitted when the line (pen) color changes to color .

注意： 通知程序信號對於特性 borderColor .

[signal] void QScatterSeries:: colorChanged ( QColor color )

This signal is emitted when the fill (brush) color changes to color .

注意： 通知程序信號對於特性 color .

[signal] void QScatterSeries:: markerShapeChanged ( QScatterSeries::MarkerShape shape )

This signal is emitted when the marker shape changes to shape .

注意： 通知程序信號對於特性 markerShape .

[signal] void QScatterSeries:: markerSizeChanged ( qreal size )

This signal is emitted when the marker size changes to size .

注意： 通知程序信號對於特性 markerSize .

[虛擬] QScatterSeries:: ~QScatterSeries ()

Deletes the scatter series.

注意： Adding the series to QChart transfers the ownership to the chart.

[override virtual] void QScatterSeries:: setBrush (const QBrush & brush )

重實現： QXYSeries::setBrush (const QBrush &brush).

另請參閱 brush ().

[override virtual] void QScatterSeries:: setPen (const QPen & pen )

重實現： QXYSeries::setPen (const QPen &pen).

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

重實現訪問函數為特性： QAbstractSeries::type .
