Answer 1

将附加数据插入工具提示的方法：

声明格式化程序

formatter: function (params) { //params can get the data needed like series name
//params is to get the corresponding data that belong to the pointer
// var index_ds = params[0].dataIndex (Can use this code to get the index of dataset which is the index where the data come from)
//Declare a variable to display the data
let additional = "Additional Data"
//If want add a new line just like 
additional += "xxxxx"
}

输出如下：
================

其他数据
xxxxx
=========
