echarts 根本使用
echarts 基本使用
最近项目需要做一下数据展示，在网上搜索了一下发现了echarts，没有接触过，正好学习一下。想要使用它主要有几个步骤：
1. 首先去官网下载一个echarts.js文件，把它引入；
2.在绘制我们想要的图之前的需要一个有宽高的容器；
3.通过echarts.init方法初始化一个echarts实例并通过setoption方法生成一个简单的图；

// Step:3 conifg ECharts's path, link to echarts.js from current page.
// Step:3 为模块加载器配置echarts的路径，从当前页面链接到echarts.js，定义所需图表路径
require.config({

echarts: './js'

});
// Step:4 require echarts and use it in the callback.
// Step:4 动态加载echarts然后在回调函数中开始使用，注意保持按需加载结构定义图表路径

只是一个带炫光的散点地图展示，具体的配置去官网查看
数据展示用它很方便，值得一看。还有就是在引入json文件时，文件名字不能是中文不然解析不出来。
