详细说明
散点数据在图表上以一组点的形式显示。每个点都指定了两个值，用于确定其在横轴和纵轴上的位置。
您可以通过在GraphsView 中创建一个ScatterSeries来呈现散点数据。通过为ScatterSeries创建XYPoints子节点（这些子节点定义了每个点的x和y值），即可将数据添加到图表中。
GraphsView {
anchors.fill: parent
axisX: ValueAxis {
max: 3
}
axisY: ValueAxis {
max: 3
}
ScatterSeries {
color: "#00ff00"
XYPoint { x: 0.5; y: 0.5 }
XYPoint { x: 1; y: 1 }
XYPoint { x: 2; y: 2 }
XYPoint { x: 2.5; y: 1.5 }
}
}通过将多个`ScatterSeries`作为GraphsView 的子元素，可以创建多个散点图。在这种情况下，应仅由一个系列定义所使用的坐标轴，因为多个定义只会覆盖之前的定义。
GraphsView {
anchors.fill: parent
ScatterSeries {
color: "#00ff00"
axisX: ValueAxis {
max: 3
}
axisY: ValueAxis {
max: 3
}
XYPoint { x: 0.5; y: 0.5 }
XYPoint { x: 1; y: 1 }
XYPoint { x: 2; y: 2 }
XYPoint { x: 2.5; y: 1.5 }
}
ScatterSeries {
color: "#ff0000"
XYPoint { x: 0.5; y: 3 }
XYPoint { x: 1; y: 2 }
XYPoint { x: 2; y: 2.5 }
XYPoint { x: 2.5; y: 1 }
}
