@xiaobaiha 这个是为了保证 smooth 后的曲线不会超过一些极值，比如分数最高分是 100，但是如果不做这个约束的话，smooth 后有可能部分曲线就会超出 100
之前有一些类似的 issue 可以参考，https://github.com/apache/incubator-echarts/issues/222
这个也会碰到一些 bad case，比如像 https://github.com/apache/incubator-echarts/issues/4556 ，应该需要有更好的算法来处理

> [#7158 (comment)](https://github.com/apache/incubator-echarts/issues/7158#issuecomment-364828528) 的算法有点问题，已经被 revert 掉了。你这边具体是觉得什么时候有问题？可否提供一个例子？
感谢回复，我是在学习echarts平滑算法时看到这里 https://github.com/apache/incubator-echarts/blob/450ee942587f51616a55feffc470eea20642831d/src/chart/line/poly.js#L239 做了对最大最小值的处理，想问下为什么要做一个这样的限制，是出于哪方面的考量？
