想通过echarts得到一份这样的地图(此处为新疆地图),首先需要一份新疆地区的json数据,还有就是echarts地图代码。
1、json数据
可以通过阿里云数据化可视平台得到:阿里云数据可视化平台
2、echarts代码如下
<template> <div class="map_content"> <div id="map-box"></div> </div> </template> <script> export default { props: { // 地图区域数据 gisData: Array, }, data() { return {
// 城市经纬度坐标 geoCoordMap : { 阿勒泰地区: [88.13963, 47.848393], 塔城地区: [82.985732, 46.746301], 克拉玛依市: [84.873946, 45.595886], 博尔塔拉蒙古: [81.984105, 44.569962], 伊犁哈萨克自治州: [80.226151, 42.713006], 阿克苏地区: [80.265068, 41.170712], 克孜勒苏柯尔克孜自治州: [74.172825, 39.713431], 喀什地区: [75.989138, 37.467664], 和田地区: [79.92533, 37.110687], 巴音郭楞蒙古自治州: [84.150969, 38.768552], 哈密市: [93.51316, 42.833248], 乌鲁木齐市: [87.497106, 42.740062], 吐鲁番市: [87.871523, 43.513961], 昌吉回族自治州: [89.315669, 44.790604] } }; }, mounted() { // dom加载完毕之后执行js let This = this; setTimeout(function() { This.drawChart(); // 展示地图 }, 500); }, methods: { // 处理地区展示数据 convertData(data) { let res = []; // 拿到key值 let geoCoordMapKeys = Object.keys(this.geoCoordMap); geoCoordMapKeys.forEach(item => { // 与传入的值相匹配 data.forEach(sItem => { if(sItem.name == item) { res.push({ name: sItem.name, dccId: sItem.dccId, value: this.geoCoordMap[item], capacityValue: sItem.value }); } }); }); return res; }, // 地图配置 geoCoordMap地区图层 data地区展示数据 drawChart() { let This = this; let data = This.convertData(This.gisData); let option = {}; let myChart = This.$echarts.init(document.querySelector("#map-box")); This.$echarts.registerMap("mapBox", require("./xinjiang.json")); myChart.clear(); myChart.off("click"); // 解绑事件处理函数。为了解决地图下钻会重复触发点击事件的问题 option = { geo: { map: "mapBox", aspectScale: 0.75, zoom: 1.2, roam: false, itemStyle: { normal: { areaColor: { type: "radial", x: 0.5, y: 0.5, r: 0.8, colorStops: [ { offset: 0, color: "#bcf9dc" }, { offset: 1, color: "#7ae0b1" } ], globalCoord: true }, shadowColor: "#7ae0b1", shadowOffsetX: 10, shadowOffsetY: 11 }, emphasis: { areaColor: "#bcf9dc", borderWidth: 0, color: "green", label: { show: false } } } }, series: [ // 默认 { map: "mapBox", type: "map", roam: false, zoom: 1.2, label: { normal: { show: false }, emphasis: { show: false } }, itemStyle: { normal: { borderColor: "#5cd59c", borderWidth: 1, areaColor: { type: "radial", x: 0.5, y: 0.5, r: 0.8, colorStops: [ { offset: 0, color: "#bcf9dc" // 0% 处的颜色 }, { offset: 1, color: "#bcf9dc" // 100% 处的颜色 } ], globalCoord: true // 缺省为 false } }, emphasis: { borderColor: "#1aa563", areaColor: "#30c47e", borderWidth: 2 } } }, // 城市 { name: "城市", coordinateSystem: "geo", type: "effectScatter", symbolSize: 0.1, // showEffectOn: "render", // rippleEffect: { // brushType: "stroke" // }, label: { normal: { formatter: function (params) { return data.find(item => item.name == params.name) == undefined ?

其中gisData的数据格式如下:
gisData: [ { name: '乌鲁木齐市', value: 123456 }, { name: '克拉玛依市', value: 223456 }, ],
