echarts 显示柱状图

1、引入

2、添加容器

3、读数据，显示图标

// 基于准备好的dom，初始化echarts图表
	        var myChart = echarts.init(document.getElementById('main'));

	        var option = {
	            title: {
	                text: '投资计划完成情况'
	            },
	            tooltip: {
	                show: true
	            },
	            toolbox: {
