我的应用程序中有两个图表，一个是柱形图，另一个是饼图。在第一列图表中，我显示了多年来的汽车销量，并在一年中向下钻取，它显示了销量 y 季度。然后有一个单独的饼图，按地区显示汽车销量。在向下钻取一个区域后，它会显示所选区域中子区域的汽车销量。 我想要的是同步这两个图表。例如，最初的柱形图显示多年来的销售额，饼图显示地区的销售额。当我点击一年时，它应该向下钻取以按季度显示销售额，饼图也应该更新以按地区显示销售额，但仅限于柱形图中选定的年份。我尝试了几种方法，但无法找到解决方案。有解决办法吗？
以下是我使用的示例代码。 https://jsfiddle.net/yasirunilan/erqm86k7/15/

最佳答案
您需要实现一个函数，该函数将迭代您拥有的所有图表，并在其内部根据您单击的点对具有相同索引的点调用 doDrilldown() 函数前。调用已创建函数的最佳位置是 chart.events.drilldown 和 chart.events.drillup 处理程序。
这是示例函数和用法:
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)
}
}
},
