先看下效果图:
就如上图所示,都是些常用的基本配置。 Legend分页,X轴设置,Y轴设置,底部缩放条设置, 数值显示样式设置,工具箱设置,自定义工具按钮, 绑定点击事件等等。这些配置代码中都做了简单的注释。下面看下代码,代码总共分为了3个js文件,分别如下:
1. option.js

option.js 是echarts的配置项,单独一个配置对象。 demo.js是一个类,里面定义了一些方法用来操作图表,改变图表的一些样式和 行为。 index.js是实际页面调用的js文件,它引入了option.js 和 demo.js。因为用了webpack 进行打包,打包后的文件名为bundle.js,所以index.html文件只引用了一个bundle.js文件。

以上就是所有的代码了,用的ES6的语法。echarts 工具箱 (toolbox) 中的数据视图按钮点击后出现的数据视图我嫌弃它太丑了,所以重新写了样式。默认情况下它是一个可编辑的多行文本框,在option.js中重新拼成了table。 效果如下图:
