效果图如下：核心代码如下：chart: { type: 'line', events: { load: function () { let chart = this const points = [] Highcharts.each(chart.series, function (s) { if (s.visible) { points.push(s.points[s.points.le

核心代码如下：plotOptions: { series: { events: { show: function () { const chart = this.chart const series = chart.series let i = series.length let otherSeries while (i--) { otherSeries = series[i];
