1. 概述
接下来使用Echarts绘制柱状图、折线图、散点图、K线图、饼状图、雷达图。
整个工程的百度云链接：https://pan.baidu.com/s/1_gyBb6pT6_fizE3SSKkO8w 提取码：4zia 。
也可以去看官方教程，不过下载了上面的源码后，例子直接可以运行，省了一点时间，官方教程网址如下，本文参考（抄袭）官方教程：https://echarts.baidu.com/echarts2/doc/example.html
2. 实例
2.1 柱状图
第一个例子是一个柱状图，绘制一个柱状图的步骤如下：
第一步：你需要先导入echarts.js 或 echarts.min.js ，百度云下载后都有。
第二步：为ECharts准备一个具备大小（宽高）的Dom， <div id="main" style="width: 600px;height:400px;"></div>
第三步：基于准备好的dom，初始化echarts实例， var myChart = echarts.init(document.getElementById('main'));
第四步：指定图表的配置项和数据，var option = { };
第五步：使用刚指定的配置项和数据显示图表，myChart.setOption(option);
下面的其它的例子和这个相似，下面就不介绍了。
