由于数据问题，导致饼图中的一项值非常大，其它值都非常的小，为了避免label重叠和事件交换的不顺畅，所以我调整的minAngle的值，这个时候却发现lableLine的长度仍然是很长，不会随着角度值变化而自动适应。

上图中的尽管角度都已经不小了，labelLine长度仍然是超长，这个不太合理

我看了下源码，在占比小于4的时候，就可能扩大或缩小绘制label的长度。在这，还有个地方不合理，就是如果那个几个比较小的label都在0度或者180度附近，照样会照成label重叠。8ce208f0869aa9aa04c297db7bd843c6
希望你们能改价一下算法，比如label的碰撞检测，然后改变labelLine的绘制角度，不要老是水平或垂直（当然这样看起来比较美观），或者更直接点，在特殊情况下将labelLine用三条直线来绘制

水平线上的连续小角度是已知问题，核心升级还有很多，等排上计划就做
