kxcc opened a new issue #10696: 【task】请提供鼠标hover图例时，显示markLine、markPoint等信息。
URL: https://github.com/apache/incubator-echarts/issues/10696
 
 
   ### What problem does this feature solve?
   当同一个图上有多个线条时，同时显示markLine会显得图表非常凌乱，可视性非常差，当用户去关注某个线条时，鼠标去hover图例（或者其他什么更好的方式），再去显示单独的线条，将更加友好
   
   ### What does the proposed API look like?
   鼠标hover图例，显示当前图例对应线条的markLine，移开时，隐藏。
   可通过事件实现，如果能够实现为配置项则更好
