在Highcharts中，當使用多個軸線時，兩個或兩個以上相反軸的刻度將會自動添加到刻度線并且刻度線數最少。這個可以設置 alignTicks 為 false 來阻止。如果網格線顯得零亂，這里有個方法來隱藏它們，就是設置 gridLineWidth 為 0。默認設置為 true。

操作一： alignTicks 默認設置為true

$(function () {
    $('#container').highcharts({
        chart: {
            //alignTicks: false,
            type: 'line'
        },
        xAxis: {
            categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
        },
        yAxis: [{
            title: {
                text: 'Primary Axis'
            },
            gridLineWidth: 0
        }, {
            title: {
                text: 'Secondary Axis'
            },
            opposite: true
        }],
        legend: {
            layout: 'vertical',
            backgroundColor: '#FFFFFF',
            floating: true,
            align: 'left',
            x: 100,
            verticalAlign: 'top',
            y: 70
        },
        tooltip: {
            formatter: function() {
                return '<b>'+ this.series.name +'</b><br/>'+
                    this.x +': '+ this.y;
            }
        },
        plotOptions: {
        },
        series: [{
            data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4]
            
        }, {
            data: [129.9, 271.5, 306.4, 29.2, 544.0, 376.0, 435.6, 348.5, 216.4, 294.1, 35.6, 354.4],
            yAxis: 1
            
        }]
    });
});

操作二： alignTicks 設置為false

$(function () {
    $('#container').highcharts({
        chart: {
            alignTicks: false,
            type: 'line'
        },
        xAxis: {
            categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
        },
        yAxis: [{
            title: {
                text: 'Primary Axis'
            }
        }, {
            title: {
                text: 'Secondary Axis'
            },
            gridLineWidth: 0,
            opposite: true
        }],
        legend: {
            layout: 'vertical',
            backgroundColor: '#FFFFFF',
            floating: true,
            align: 'left',
            x: 100,
            verticalAlign: 'top',
            y: 70
        },
        tooltip: {
            formatter: function() {
                return '<b>'+ this.series.name +'</b><br/>
                '+
                    this.x +': '+ this.y;
            }
        },
        plotOptions: {
        },
        series: [{
            data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4]
            
        }, {
            data: [129.9, 271.5, 306.4, 29.2, 544.0, 376.0, 435.6, 348.5, 216.4, 294.1, 35.6, 354.4],
            yAxis: 1
            
        }]
    });
});
