javascript - 单击具有多个系列的 highcharts 上的事件

Question

当我的图表上有多个具有交叉点的系列时，点击事件似乎根本不会触发。这是一个例子:

如果您查看所有 3 个系列相交的 April 并尝试单击该点，它不会发出警报，但如果您检查任何不相交的点，它们会正确发出警报。

<div id="container" style="min-width: 400px; height: 400px; margin: 0 auto"></div>

我试过添加 index/zIndex 来优先处理某些点，但似乎没有帮助。

为您想出了一个不错的解决方案。因为单独的线事件不可靠，所以我为图表上被单击的任何点创建了一个事件，然后使用事件信息提取系列的名称并运行检查以查看它是否是我想要的。

这是我添加的 Javascript:http://jsfiddle.net/agnHV/24/

plotOptions: {
    series: {
      point: {
        events: {
        click: function(e){
          var seriesName = e.point.series.name;
          if(seriesName == "Temperature") {
            console.log("Clicked Temperature Line");
          }
          else if(seriesName == "Sea-Level Pressure") {
            console.log("Clicked Sea-Level Line");
          }
          else if(seriesName == "Rainfall") {
            console.log("Clicked Rainfall Bar");
          }
        }
      }
    }
  }
}

$(function () {
        $('#container').highcharts({
            chart: {
                zoomType: 'xy'
            },
            title: {
                text: 'Average Monthly Weather Data for Tokyo'
            },
            subtitle: {
                text: 'Source: WorldClimate.com'
            },
            xAxis: [{
                categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
                    'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
            }],
            yAxis: [{ // Primary yAxis
                labels: {
