        y: 2, 
        x: 1

        name: 'Point 4', 
        x: 2, 
        y: 8 
       }, { 
        name: 'Point 5', 
        x: 3, 
        y: 10

Answer 1

添加以下代碼，然後看highcharts documentation

plotOptions: { 
    line: { 
     findNearestPointBy: 'x', //or "xy" to both axis 
     marker: { 
     enabled: true 
     } 
    } 
    }
