//1、下载并引入Echarts.js文件，图表依赖该js库
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<style>
.box{
height:600px;
width:1200px;
background-color: lightpink;
}
</style>
</head>
<body>
//2、准备一个具备大小的DOM容器（容器有宽度与高度），要将图表放到该容器当中
<div class = "box"></div>
<script src="js/echarts.min.js"></script>
<script>
//3、初始化Echarts实例对象，实例化图表 echarts.init(DOM容器);
var mychart = echarts.init(document.querySelector(".box"));
//4、指定配置项和数据（option），根据具体需求修改配置选项
option = {
title: {
text: '堆叠区域图'
},
tooltip: {
trigger: 'axis',
axisPointer: {
type: 'cross',
label: {
backgroundColor: '#6a7885'
}
}
},
legend: {
data: ['邮件营销', '联盟广告', '视频广告', '直接访问', '搜索引擎']
},
toolbox: {
feature: {
saveAsImage: {}
}
},
grid: {
left: '3%',
right: '4%',
bottom: '3%',
containLabel: true
},
xAxis: [
{
type: 'category',
boundaryGap: false,
data: ['周一', '周二', '周三', '周四', '周五', '周六', '周日']
}
],
yAxis: [
{
type: 'value'
}
],
series: [
{
name: '邮件营销',
type: 'line',
stack: '总量',
areaStyle: {},
data: [120, 132, 101, 134, 90, 230, 210]
},
{
name: '联盟广告',
type: 'line',
stack: '总量',
areaStyle: {},
data: [220, 182, 191, 234, 290, 330, 310]
},
{
name: '视频广告',
type: 'line',
stack: '总量',
areaStyle: {},
data: [150, 232, 201, 154, 190, 330, 410]
},
{

type: 'line',
stack: '总量',
areaStyle: {},
data: [320, 332, 301, 334, 390, 330, 320]
},
{
name: '搜索引擎',
type: 'line',
stack: '总量',
label: {
normal: {
show: true,
position: 'top'
}
},
areaStyle: {},
data: [820, 932, 901, 934, 1290, 1330, 1320]
}
]
};
//5.把配置项option给实例对象mychart
mychart.setOption(option);
