详细描述

A line chart is used to show information as a series of data points connected by straight lines.

The following QML example shows how to create a simple line chart:


  ChartView {
      title: "Line"
      anchors.fill: parent
      antialiasing: true

      LineSeries {
          name: "LineSeries"
          XYPoint { x: 0; y: 0 }
          XYPoint { x: 1.1; y: 2.1 }
          XYPoint { x: 1.9; y: 3.3 }
          XYPoint { x: 2.1; y: 2.1 }
          XYPoint { x: 2.9; y: 4.9 }
          XYPoint { x: 3.4; y: 3.0 }
          XYPoint { x: 4.1; y: 3.3 }
      }
  }
