使用ArcGIS API for JavaScript, 以ArcGIS Server提供的服务为底图，实现eCharts的迁徙图。

效果如下：

首先下载ArcGIS地图扩展，网址：https://github.com/wandergis/arcgis-echarts3

下载完成后，可以查看作者提供的example，里面有两个示例，但并未提供使用教程，而且实例可能并不能成功打开，这与我们的环境配置有关。

下面是实现迁徙图的具体步骤：

1.配置Echarts3Layer.js

将src文件夹拷贝至ArcGIS API for JavaScript配置路径下，为了便于引用，拷贝到与init.js处于同一级目录。笔者的路径为：D:\program\Web\webapps\arcgis_js_api\library\3.23\3.23，

 

2.创建一个项目

创建一个项目，将ArcGIS扩展中的dist文件夹拷贝到项目文件夹中，在项目文件夹新建一个html文件。

3.引入js和css文件

要求引入的文件有三个。引入文件一定要按照一定的顺序，否则会出错。main.js一定要在引入init.js之前引入

<link  rel="stylesheet"  type="text/css" href="http://localhost:8080/arcgis_js_api/library/3.23/3.23/esri/css/esri.css" />
<script src="dist/main.js"></script>
<script src="http://localhost:8080/arcgis_js_api/library/3.23/3.23/init.js"></script>

4.加载ArcGIS服务地图

与ArcGIS API for JavaScript中加载的方法一样，没有改变，此处我们使用官方提供的底图 basemap:"osm"

var map;
require(["esri/map","eCharts/Echarts3Layer"],function (Map,Echarts3Layer) {map=new Map("mapDiv",{basemap:"osm",logo:false,zoom:5,center:[100,30]})

5.加载eChart

在加载ArcGIS服务代码下添加以下代码，将eCharts添加到图层

map.on('load',function () {//eChart添加到图层var overlay = new Echarts3Layer(map, echarts);var chartsContainer = overlay.getEchartsContainer();var myChart = overlay.initECharts(chartsContainer);option = {//设置配置选项}myChart.setOption(option);
}

6.加载数据

7.设置渲染参数和配置项

渲染参数是指线条和点的样式，动画的样式等。配置项（option）是决定数据的展示方式及展示内容。

var color = ['#a6c84c', '#ffa022', '#46bee9'];var series = [];[['北京', BJData], ['上海', SHData], ['广州', GZData]].forEach(function (item, i) {series.push({name: item[0] + ' Top10',type: 'lines',zlevel: 1,effect: {show: true,period: 6,trailLength: 0.7,color: '#fff',symbolSize: 3},lineStyle: {normal: {color: color[i],width: 0,curveness: 0.2}},data: convertData(item[1])},{name: item[0] + ' Top10',type: 'lines',zlevel: 2,effect: {show: true,period: 6,trailLength: 0,symbol: planePath,symbolSize: 15},lineStyle: {normal: {color: color[i],width: 1,opacity: 0.4,curveness: 0.2}},data: convertData(item[1])},{name: item[0] + ' Top10',type: 'effectScatter',coordinateSystem: 'geo',zlevel: 2,rippleEffect: {brushType: 'stroke'},label: {normal: {show: true,position: 'right',formatter: '{b}'}},symbolSize: function (val) {return val[2] / 8;},itemStyle: {normal: {color: color[i]}},data: item[1].map(function (dataItem) {return {name: dataItem[1].name,value: geoCoordMap[dataItem[1].name].concat([dataItem[1].value])};})});});option = {
//        backgroundColor: '#404a59',title: {text: 'ArcGIS JS API扩展Echarts3之模拟迁徙',subtext: 'Develop By WanderGIS',left: 'center',textStyle: {color: '#fff'}},tooltip: {trigger: 'item'},legend: {orient: 'vertical',top: 'bottom',left: 'right',data: ['北京 Top10', '上海 Top10', '广州 Top10'],textStyle: {color: '#fff'},selectedMode: 'single'},geo: {map: '',label: {emphasis: {show: false}},roam: true,itemStyle: {normal: {areaColor: '#323c48',borderColor: '#404a59'},emphasis: {areaColor: '#2a333d'}}},series: series};
