详细描述
The QScatterSeries class presents data in scatter charts.
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);
For more information, see ScatterChart Example and Scatter Interactions Example.
成员类型
enum QScatterSeries::MarkerShape
This enum value describes the shape used when rendering marker items.
| Constant | Value | Description |
|---|---|---|
QScatterSeries::MarkerShapeCircle | 0 | The marker is a circle. This is the default value. |
QScatterSeries::MarkerShapeRectangle | 1 | The marker is a rectangle. |
属性
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.
访问函数:
| QColor | borderColor() const |
| void | setBorderColor(const QColor &color) |
Notifier signal:
| void | borderColorChanged(QColor color) |
参见 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, for example.
访问函数:
| QBrush | brush() const |
| virtual void | setBrush(const QBrush &brush) |
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.
访问函数:
| virtual QColor | color() const |
| virtual void | setColor(const QColor &color) |
Notifier signal:
| void | colorChanged(QColor color) |
参见 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.
访问函数:
| MarkerShape | markerShape() const |
| void | setMarkerShape(MarkerShape shape) |
Notifier signal:
| void | markerShapeChanged(MarkerShape shape) |
参见 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.
访问函数:
| qreal | markerSize() const |
| void | setMarkerSize(qreal size) |
Notifier signal:
| void | markerSizeChanged(qreal size) |
成员函数
QScatterSeries::QScatterSeries(QObject *parent = Q_NULLPTR)
Constructs a series object that is a child of parent.
QScatterSeries::~QScatterSeries()
Deletes the scatter series.
Note: Adding the series to QChart transfers the ownership to the chart.
[signal] void QScatterSeries::borderColorChanged(QColor color)
This signal is emitted when the line (pen) color changes to color.
Note: Notifier signal for property borderColor.
[signal] void QScatterSeries::colorChanged(QColor color)
This signal is emitted when the fill (brush) color changes to color.
Note: Notifier signal for property color.
[signal] void QScatterSeries::markerShapeChanged(MarkerShape shape)
This signal is emitted when the marker shape changes to shape.
Note: Notifier signal for property markerShape.
[signal] void QScatterSeries::markerSizeChanged(qreal size)
This signal is emitted when the marker size changes to size.
Note: Notifier signal for property markerSize.
[virtual] void QScatterSeries::setBrush(const QBrush &brush)
Reimplemented from QXYSeries::setBrush().
Note: Setter function for property brush.
参见 brush().
[virtual] void QScatterSeries::setPen(const QPen &pen)
Reimplemented from QXYSeries::setPen().
[virtual] QAbstractSeries::SeriesType QScatterSeries::type() const
Reimplemented from QAbstractSeries::type().
