我想做类似的事情：
drillUp: function(){
//get point details by using something like this or this.point

}

You need to catch the event. See the chart.events.drillupAPI doc.
To get the series and points in the series you would do something like:
你需要抓住event. 请参阅chart.events.drillupAPI 文档。要获得系列和系列中的积分，您可以执行以下操作：
events: {
drillup: function (e) {
console.log(this);
console.log(this.options.series[0].name);
console.log(this.options.series[0].data[0].name);
}
}
Since you did not state which series or points you wanted this is the most general method.
由于您没有说明您想要哪个系列或点，这是最通用的方法。

chart: {
type: 'column',
events: {
drillup: function (e) {
alert(e.seriesOptions.name);
}
}
}
From the below line,
从下面的行，
e.seriesOptions.name
e.seriesOptions.name
You will get the series name, which you are loading, by clicking that back button(drill up button).
单击后退按钮（向上钻取按钮），您将获得正在加载的系列名称。
