Question

我正在使用highCharts明细。我的图表是在钻取之前正确绘制的图表。列和样条曲线在图形中根据X轴和Y轴正确获取绘图，但在向下钻取后，图形样条曲线不会根据Y轴绘制。我想在下钻之前绘制样条曲线。

这是我的HTML

<script src="http://code.highcharts.com/highcharts.js"></script>
<script src="http://code.highcharts.com/modules/drilldown.js"></script>
<div id="container" style="min-width: 310px; height: 400px; margin: 0 auto"></div>

这是我的js代码。

    $(function () {
    $('#container').highcharts({
        chart: {
            type: 'column',
            zoomType: 'xy',
            events: {
                drilldown: function (e){
                    if (!e.seriesOptions) {
                        var chart = this,
                        drilldowns = {
                            '2015':{

在钻取事件中，您正在创建新的样条线系列，并且您没有为它们指定y轴 - 默认情况下，它们将使用第一个y轴进行缩放。

为系列指定正确的yAxis（在您的示例中应为1），并且将按预期绘制样条线。

 drilldownsLines = {
                        '2015':{
                            type: 'spline',
                            name: '2015',
                            data: [
                                ['Q4-2015',11.45]
                            ],
                            yAxis: 1
                        },
                            '2016':{
                            type: 'spline',
                            name: '2016',
                            yAxis: 1,
                            data: [
                                ['Q2-2016',11.2],
                                ['Q3-2016',11.5]
                            ]
                        }
                    },
