一、定义容器变量并获取页面div元素

1 var

二、初始化容器

1 var

三、通过option变量编辑图表

1 var

四、完整的echarts柱状图饼状图js代码

1 var chartDom = document.getElementById('chart3');
2 var myChart = echarts.init(chartDom);
3 var option;
4 var successdata;
5 var dataMap = {};
6 //给中间的图添加数据
7 $.ajax({
8 url:"/get_x",
9 success: function(data) {
10 successdata=data.data
11 console.log(successdata[1])
12 console.log("9-1 name : "+successdata[0][0][0])
13 console.log("9-1 cnt : "+successdata[0][0][1])
14 console.log("9-1 round : "+successdata[0][0][2])
15 //数量
