我们在前面几个章节已经介绍了AQI雷达图和自定义雷达图，本章节我们重点介绍多雷达图的实现。
echarts 多雷达图实例
1，新建静态页面demo.html,并引入echarts的js库，在这里我们引入的是网络地址
<!-- V型知识库 www.vxzsk.com 原创--> <script type="text/javascript" src="http://echarts.baidu.com/gallery/vendors/echarts/echarts-all-3.js"></script>
2，雷达图容器html代码，只需一行html代码
<div id="container" style="height: 500px"></div>
雷达图容器高度为500px,宽度默认，并且div的id号为container。
3，javascript实现代码
<script type="text/javascript">
var dom = document.getElementById("container");
var myChart = echarts.init(dom);
var app = {};
app.title = 'v型知识库原创-www.vxzsk.com';
var option = null;
option = {
title: {
text: '多雷达图'
},
tooltip: {
trigger: 'axis'
},
legend: {
x: 'center',
data:['某软件','某主食手机','某水果手机','降水量','蒸发量']
},
radar: [
{
indicator: [
{text: '品牌', max: 100},
{text: '内容', max: 100},
{text: '可用性', max: 100},
{text: '功能', max: 100}
],
center: ['25%','40%'],
radius: 80
},
{
indicator: [
{text: '外观', max: 100},
{text: '拍照', max: 100},
{text: '系统', max: 100},
{text: '性能', max: 100},
{text: '屏幕', max: 100}
],
radius: 80,
center: ['50%','60%'],
},
{
indicator: (function (){
var res = [];
for (var i = 1; i <= 12; i++) {
res.push({text:i+'月',max:100});
}
return res;
})(),
center: ['75%','40%'],
radius: 80
}
],
series: [
{
type: 'radar',
tooltip: {
trigger: 'item'
},
itemStyle: {normal: {areaStyle: {type: 'default'}}},
data: [
{
value: [60,73,85,40],
name: '某软件'
}
]
},
{
type: 'radar',
radarIndex: 1,
data: [
{
value: [85, 90, 90, 95, 95],
name: '某主食手机'
},
{
value: [95, 80, 95, 90, 93],
name: '某水果手机'
}
]
},
{
type: 'radar',
radarIndex: 2,
itemStyle: {normal: {areaStyle: {type: 'default'}}},
data: [
{
name: '降水量',
value: [2.6, 5.9, 9.0, 26.4, 28.7, 70.7, 75.6, 82.2, 48.7, 18.8, 6.0, 2.3],
},
{
name:'蒸发量',
value:[2.0, 4.9, 7.0, 23.2, 25.6, 76.7, 35.6, 62.2, 32.6, 20.0, 6.4, 3.3]
}
]
}
]
};4，用浏览器打开demo.html，效果如下
如上图所示，多个雷达图已经显示出来了。
5，多雷达图demo.html完整代码
<!DOCTYPE html>
<head>
<meta charset="utf-8">

<body >
<div id="container" style="height: 500px"></div>

value:[2.0, 4.9, 7.0, 23.2, 25.6, 76.7, 35.6, 62.2, 32.6, 20.0, 6.4, 3.3]
}
]
}
]
};
if (option && typeof option === "object") {
myChart.setOption(option, true);
}
</script>
</body>
</html>把上述代码复制到一个静态HTML页面中即可实现多雷达图效果。
