### What problem does this feature solve?
### 实时曲线
问题描述：Echarts官网您好，目前有个需求，也是非常具有挑战性的折线功能，可以帮助使用折线图的人，操作起来更加灵活，功能如下

数据是通过webSocket获取，有四条Y轴左右个两条，一条X轴时间线

鼠标悬停到当前Y轴刻度线上，鼠标滚轮操作可以放大缩小当前Y轴对应的这条折线，同时Y轴刻度也发生变化，鼠标拖动Y轴刻度线可以移动Y轴对应的这条折线的位置，每一个Y轴对应一条折线的操作，一一对应，单独的放大缩小折线，移动位置，目的是为了对比数据。

鼠标右键或者其它方式，可以设置拐点，一条首拐点，一条末拐点，把这一段时间，或者数据取出来，目的是记录异常数据，发送出去并记录，如下图所示

I'm sorry to close this issue for it lacks the necessary title. Please provide **a _descriptive_ and as _concise_ as possible title to describe your problems or requests** and then the maintainers or I will reopen this issue.
Every good bug report or feature request starts with a title. Your issue title is a critical element as it's the first thing maintainers see.
A good issue title makes it easier for maintainers to understand what the issue is, easily locate it, and know what steps they'll need to take to fix it.
Moreover, it's better to include keywords, as this makes it easier to find the issue self and similar issues in searches.
