先上图，要不感觉没有说服力：
飞线图应该是大屏中很常见的一种了，通常你可以很轻易的用datav做一个飞线图，而且datav做的大屏逼格真的很高，本身也是开源免费的项目，开箱即用，上手简单……行了回归正题，我们使用echarts自己配置一个飞线图。当然echarts配置起来也不复杂，只要查看下面对应几个属性的配置就ok了
三个配置，geo画地图，effectScatter在地图上画散点图，lines画线集，熟悉echarts配置项的看到这里基本就不用看了，自己看下配置文档马上就能撸一个出来，接下来我们按部就班把上面那个例子撸出来。
1、基础环境准备
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>飞线图</title>
<script src="https://cdn.bootcss.com/echarts/4.4.0-rc.1/echarts-en.js"></script>
<style>
html{
height: 100%;
}
body{
height: 100%;
margin: 0;
padding: 0;
background-color:#2F4056;
}
</style>
</head>
<body>
<div id="chart-box" style="width:100%; height:100%;"></div>
<script type="text/javascript">
const chart = echarts.init(document.getElementById(‘chart-box‘));
const xhr = new XMLHttpRequest();
xhr.open(‘get‘,‘https://geo.datav.aliyun.com/areas/bound/530000_full.json‘,true)
xhr.send(null)
xhr.onreadystatechange = () => {
if ((xhr.status >= 200 && xhr.status < 300) || xhr.status == 304){
const data = JSON.parse(xhr.responseText);
} else {
alert(xhr.status);
}
}
</script>
</body>
这里为了简便处理，直接引用cdn上的echarts和datav官方的地图json文件，当然地图json文件也可以从http://geojson.io/#map=12/30.2275/120.1777获得；
好了，上面代码已经初始化了chart容器，然后请求获取了云南省地图json数据
2、画地图
echarts.registerMap(‘yns‘, data); const option ={ title: { text: ‘云南省‘, }, geo: { map: ‘yns‘, zlevel: 10, show:true, layoutCenter: [‘50%‘, ‘50%‘], roam: false, layoutSize: "90%", zoom: 1, label: { normal: { show: true, textStyle:{ fontSize:12, color: ‘#43D0D6‘ } } }, itemStyle: { normal: { color: ‘#062031‘, borderWidth: 1.1, borderColor: ‘#43D0D6‘ } }, emphasis: { areaColor: ‘#FFB800‘, label:{ show:false } } } } chart.setOption(option);
好了，这个geo配置已经能画出一个完整的云南地图了，这里因为要在地图上画线集和散点，所画地图要用geo而不是serise的map
3、配置散点和线集，具体的配置项的含义请参考echarts官网，下面附上完整代码，此代码直接复制粘在html，在有网络的环境下打开就能运行
