## Detailed Description

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 Chart"
         anchors.fill: parent
         antialiasing: true

         LineSeries {
             name: "Line"
             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 }
         }
     }
