我在多个系列跌倒上看到了一些示例，但是我看不到关于如何在第二次钻探序列中的第二个项目上进行第三级钻探的示例。
例如。
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:
MSIE之后，我还没有看到一个示例，该示例是该系列中的第二个项目（MSIE 6.0）设置为第三级。我只看到了第一个项目（MSIE 8.0）的示例。有没有办法设置第二个或第三个项目进入第三级？
