   Totoally agreed.
   But I do have data with a large amount of series need to render in single line chart.
   Most time, the chart tells the trend of data and helps targeting series that have outliers. In the long run, it should be automaticly identified by intelligent algorithms.
   
   
   [tooltip.triggerOn](https://echarts.apache.org/en/option.html#tooltip.triggerOn) set to 'click' could help to improve the performance, cause we don't need to trigger tooltip everytime the mouse cursor over the chart
   
   > Usually, even 30 line series are hard to read in a chart, but 300 (!?) - impressive tapestry...
