### What problem does this feature solve? 在使用 5.3之后 使用 valueFormatter 可以显示方便去格式化显示series的数据 但是在需要做一些折扩展显示: 如下图 需要在 tooltip 底部显示数据的汇总 .. 平均值 在tooltip 的顶部格式化显示日期就不得不放弃使用 valueFormatter 而需要使用原来的 formatter 方法 <img width="393" alt="image" src="https://user-images.githubusercontent.com/5426866/204747098-c42ec56d-ac47-406c-953f-f751723f4b39.png";> ### What does the proposed API look like? 希望可以增加一些方法来处理 头部跟底部的 显示 tooltip: { trigger: 'axis', headerFormatter: header => `${new Date(header).toDateString()}`, valueFormatter: value => `${value.toFixed(2)}`, footerFormatter: params => { //do process 计算汇总数据 } } -- This is an automated message from the Apache Git Service.
