ScatterSeries QML Type▲
-
Import Statement: import QtCharts 2.4
-
Inherits:: XYSeries
-
Instantiates:: QScatterSeries
Detailed Description▲
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 QML code shows how to create a chart with two simple scatter series:
ChartView {
title: "Scatters"
anchors.fill: parent
antialiasing: true
ScatterSeries {
id: scatter1
name: "Scatter1"
XYPoint { x: 1.5; y: 1.5 }
XYPoint { x: 1.5; y: 1.6 }
XYPoint { x: 1.57; y: 1.55 }
XYPoint { x: 1.8; y: 1.8 }
XYPoint { x: 1.9; y: 1.6 }
XYPoint { x: 2.1; y: 1.3 }
XYPoint { x: 2.5; y: 2.1 }
}
ScatterSeries {
name: "Scatter2"
XYPoint { x: 2.0; y: 2.0 }
XYPoint { x: 2.0; y: 2.1 }
XYPoint { x: 2.07; y: 2.05 }
XYPoint { x: 2.2; y: 2.9 }
XYPoint { x: 2.4; y: 2.7 }
XYPoint { x: 2.67; y: 2.65 }
}
