使用滚动条的Highcharts多级向下钻取仅绘制部分列

Question

我需要绘制一个包含多级下钻的图表。因为每个级别具有不同的列数，所以我将在钻取/钻取事件中更新x轴的最大值。然后我注意到，一些钻取图表搞砸了。酒吧只画顶部。例如，y = 3068。图表仅从1500到3068。底部被截断。

$(function () {

    // Create the chart
    Highcharts.chart('container', {
        chart: {
            type: 'column',
            events: {
                load: function (e) {
                     this.xAxis[0].update({ max: 5 }); 
                },
                drilldown: function (e) {
                    this.xAxis[0].update({ min: 0 });
                    this.yAxis[0].update({ min: 0 });
                    if (e.seriesOptions.data.length > 14)
                        this.xAxis[0].update({ max: 15 });
                    else {
                        this.xAxis[0].update({ max: e.seriesOptions.data.length - 1 });
                   }
                },
                drillup: function (e) {
                    this.xAxis[0].update({ min: 0 });
                    this.yAxis[0].update({ min: 0 });
                    if (e.seriesOptions.data.length > 14)
                        this.xAxis[0].update({ max: 15 });
                    else {
                        this.xAxis[0].update({ max: e.seriesOptions.data.length - 1 });
                    }
                }
             }
