TITLE

Legend event monitoring problem

BODY

What problem does this feature solve?

There is a mousemover event in the legend, but .on has no function that can listen to the event, only a legendselectchanged is listening to click, I hope to give legend a function to listen to mousemover, thank you. The pie chart I use has this problem, and everything else should have this problem as well.

What does the proposed API look like?

。。。

命名上应该叫 legendmouseover ，建议自己支持一下，参考 #17849

并不可以呀this.chart.on("legendmouseover",params=>{
console.log(params);
})
不生效

现在没有支持，我的意思是说如果你要新增的话，命名应该叫这个

嗯嗯，好的好的，没事了，你是说我自己改源码提交是吧，哈哈，我现在用dispatchAction 里的highlight和downplay然后自己定义div 添加 @click@mouseOver @mouseleave 完成效果的，

哈哈其实mouseover应该对应mouseout
