同步两个高图以立即向下钻取

Question

我的应用程序中有两个高图,一个是柱形图,另一个是饼图.在第一个柱形图中,我显示了多年来的汽车销售情况,并且在一年内向下钻取时显示销售额为几个季度.然后是一个单独的饼图,显示按地区划分的汽车销售情况.在向下钻取一个区域时,它显示所选区域中子区域的汽车销售.我想要的是同步这两个图表.例如,最初的柱形图显示了多年的销售额,饼图显示了区域内的销售额.当我点击一年时,它应向下钻取以按季度显示销售额,饼图也应该更新以按区域显示销售额,但仅在列图表中显示该选定年份.我尝试了几种方法,但无法得到解决方案.有没有解决这个问题.

以下是我使用的示例代码. https://jsfiddle.net/yasirunilan/erqm86k7/15/

Answer 1

您需要实现一个函数,该函数将迭代您拥有的所有图表,并在其内部doDrilldown()根据您之前单击的点调用具有相同索引的点上的函数.调用创建函数的最佳位置是chart.events.drilldown和chart.events.drillup处理程序.

以下是示例函数和用法:

function syncCharts(e, chart) {
  return e.type === 'drilldown' ?
    Highcharts.charts.forEach(c => {
      if (c !== chart) {
        var series = c.series[0],
          point = series.points[e.point.index];

        point.doDrilldown()
      }
    }) :
    Highcharts.charts.forEach(c => {
      c.drillUp();
    })
}

用法:

  chart: {
    type: 'column',
    events: {
      drilldown(e) {
        syncCharts(e, this)
      },
      drillup(e) {
        syncCharts(e, this)
      }
    }
  },
