我看到了一些关于多个系列故事的例子，但是我没有看到关于如何在第二个向下钻取系列的第二个项目上进行第三级深入挖掘的示例。
代表example。
drilldown: {
name: 'MSIE versions',
categories: ['MSIE 8.0', 'MSIE 6.0', 'MSIE 7.0', 'MSIE 9.0'],
level: 1,
data: [{
y: 33.06,
drilldown: {
level: 2,
name: 'drilldown next level',
categories: ['a', 'b', 'c'],
data: [23,54,47],
color: colors[0]
}
}, 10.85, 7.35, 2.41],
color:
在MSIE之后，我还没有看到一个例子，系列中的第二项（MSIE 6.0）被设置为进入第3级。我只看过第一项（MSIE 8.0）的例子。有没有办法将第二个或第三个项目设置为第3级？
