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);
This enum value describes the shape used when rendering marker items.
常量 | 值 | 描述 |
---|---|---|
QScatterSeries::MarkerShapeCircle
|
0
|
The marker is a circle. This is the default value. |
QScatterSeries::MarkerShapeRectangle
|
1
|
The marker is a rectangle. |
This property holds the color used to draw the marker borders.
This is a convenience property for modifying the color of the pen.

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。
访问函数:
QBrush | brush () const |
virtual void | setBrush (const QBrush & brush ) override |
This property holds the color used to fill the series markers.
This is a convenience property for modifying the color of the brush.

This property holds the shape of the marker used to render the points in the series.
The default shape is MarkerShapeCircle .

This property holds the size of the marker used to render the points in the series.
The default size is 15.0.
