我的饼图有三重钻取。我正在尝试创建一个按钮，允许您将整个图表重置为原始的向下钻取状态。我看了一个没有深入分析的旧实现，无法使用我的解决方案（请参阅此处Resetting Highcharts to initial state）。
我当前的JSFiddle有我尝试使用该线程复制的内容。 你可以在这里看到：http://jsfiddle.net/vsFLK/

无论如何，我可以让一个按钮将整个图表重置为最初的向下钻取，无论你在哪个级别？

首先，为什么要创建两次图表？删除额外代码后，您可以使用下面的简单chart.setChart()功能评论：// restore - 这意味着完全按照您的需要恢复图表。
答案 1 :(得分：0)
当前，您可以重复使用drillUp方法：
document.getElementById('drillUp').addEventListener('click', function(){
chart.drillUp();
if(chart.series[0].name !== "someName"){
chart.drillUp();
}
});
