Describe the feature / 功能描述

传入point[x,y]，返回对应的tooltipItems。
使用场景：通过"plot:click"点击返回坐标，调用chart.getTooltipItems()获得数据，完成后续业务逻辑。

4.0 的"tooltip:change" 事件也可以实现类似效果，考虑先实现其中一种

我想尝试一下，有 v4 的效果展示样例吗？我参照一下，实现后放到 v5 官网上。

貌似 tooltip:change 位置变化的回调函数可以通过监听 tooltip:show 等价实现。

现在更需要的是一个 tooltip 渲染数据（内部渲染内容）发生变化的监听，还是 tooltip 位置发生变化的监听呢？

getTooltipItems其实就是返回Point(x,y)距离最近的元素的tooltipItems。
依赖的业务场景：点击图上任何位置，获取最近的元素的信息，做相应的展示更新。
现在看来tooltip:show可以等价实现，那感觉getTooltipItems的优先级没有那么高了，看下有没有更依赖这个api的场景吧
