1.下载echarts.js 文件，图表依赖这个库
下载地址
echarts CDN by jsDelivr - A CDN for npm and GitHub
选择 dist/echarts.js，点击并保存为 echarts.js 文件。
2.准备一个div 容器
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
<script src="echarts.js"></script>
<style>
div{
width: 400px;height: 400px;
background-color: pink;
}
</style>
</head>
<body>
<div></div>
</body>
</html>
3.通过 [echarts.init]方法初始化一个 echarts 实例
var myEcharts = echarts.init($("div"));
4.通过 option 方法配置
// 2.指定配置项
var option = {
title: {
text: 'Referer of a Website',
subtext: 'Fake Data',
left: 'center'
},
tooltip: {
trigger: 'item'
},
legend: {
orient: 'vertical',
left: 'left'
},
series: [
{
name: 'Access From',
type: 'pie',
radius: '50%',
data: [
{ value: 1048, name: 'Search Engine' },
{ value: 735, name: 'Direct' },
{ value: 580, name: 'Email' },
{ value: 484, name: 'Union Ads' },
{ value: 300, name: 'Video Ads' }
],
emphasis: {
itemStyle: {
shadowBlur: 10,
shadowOffsetX: 0,
shadowColor: 'rgba(0, 0, 0, 0.5)'
}
}
}
]
};
5。实例对象set 设置配置对象
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
<script src="jquery.js"></script>
<script src="echarts.js"></script>
<style>
div{
width: 400px;height: 400px;
background-color: pink;
}
</style>
</head>
<body>
<div></div>
<script>
$(function(){
// 1.实例化
var myEcharts = echarts.init(document.querySelector("div"));
// 2.指定配置项
var option = {
title: {
text: 'Referer of a Website',
subtext: 'Fake Data',
left: 'center'
},
tooltip: {
trigger: 'item'
},
legend: {
orient: 'vertical',
left: 'left'
},
series: [
{
name: 'Access From',
type: 'pie',
radius: '50%',
data: [
{ value: 1048, name: 'Search Engine' },
{ value: 735, name: 'Direct' },
{ value: 580, name: 'Email' },
{ value: 484, name: 'Union Ads' },
{ value: 300, name: 'Video Ads' }
],
emphasis: {
itemStyle: {
shadowBlur: 10,
shadowOffsetX: 0,
shadowColor: 'rgba(0, 0, 0, 0.5)'
}
}
}
]
};
// 把我们配置的optiong 给我们创建的实例
myEcharts.setOption( option) ;
})
</script>
</body>
</html>
