最终结果

截图如下：

这里的数据都是从Mysql数据库中直接读取到的，下面演示下过程，把后端的数据通过Thymeleaf，把数组传输给前端的JS。

 

过程

这里曲线的存储结构是这样的：

其中的getDataList()的结构是这样的

这里可以看到是一个存储了String的ArrayList，其中里面的数据其实是Mysql中的数据，数据如下：

前端处理的关键如下：

这里要注意：<script这里一定要加 in:inline="javascript"

并且使用var这个JavaScript的万金油去处理；

曲线显示的时候，这样处理就可以了：

相关源码如下：

<script th:inline="javascript">
    var dataList = [[${curveData1}]];
    console.log(dataList);
    var dom = document.getElementById("container");
    var myChart = echarts.init(dom);

    option = {
        xAxis: {
