Echarts+Bmap做一个简单的地图的具体流程

使用Echarts+Bmap来做的一个简单的地图展示如下（可点击，可放大）：

 一、引入Echarts的js文件和自己的百度地图ak（ak没有可申请）

<script src="assets/js/echars/echarts.js"></script>
<script src="assets/js/echars/extension/bmap.js"></script>
<script type="text/javascript" src="http://api.map.baidu.com/getscript?v=3.0&ak=个人百度地图ak"></script>
<script type="text/javascript" src="http://api.map.baidu.com/getscript?v=3.0&type=webgl&ak=个人百度地图ak"></script>

bmap是echarts中的集成地图，如果没有引入bmap文件，代码将出现不报错，不显示地图问题！ 

申请百度地图ak可参考一下连接：

二、准备地图容器，设置宽高

<div id="mapCenter" style="width: 100%; height: 330px"></div>

三、再编写js部分，初始化echarts对象，配置option

  //地图 var myChart1 = echarts.init(document.getElementById("mapCenter"));//此为模拟数据const data = [{ name: "南昌", value: 234 },{ name: "杭州", value: 206 },{ name: "苏州", value: 266 },{ name: "上海", value: 322 },{ name: "南京", value: 982 },{ name: "郑州", value: 278 },{ name: "湖南", value: 2725 },{ name: "天津", value: 2928 },{ name: "黑龙江", value: 2275 },];const geoCoordMap = {海门: [121.15, 31.89],鄂尔多斯: [109.781327, 39.608266],招远: [120.38, 37.35],舟山: [122.207216, 29.985295],齐齐哈尔: [123.97, 47.33],盐城: [120.13, 33.38],赤峰: [118.87, 42.28],青岛: [120.33, 36.07],乳山: [121.52, 36.89],金昌: [102.188043, 38.520089],泉州: [118.58, 24.93],莱西: [120.53, 36.86],日照: [119.46, 35.42],胶南: [119.97, 35.88],南通: [121.05, 32.08],拉萨: [91.11, 29.97],云浮: [112.02, 22.93],梅州: [116.1, 24.55],文登: [122.05, 37.2],上海: [121.48, 31.22],攀枝花: [101.718637, 26.582347],威海: [122.1, 37.5],承德: [117.93, 40.97],厦门: [118.1, 24.46],汕尾: [115.375279, 22.786211],潮州: [116.63, 23.68],丹东: [124.37, 40.13],太仓: [121.1, 31.45],曲靖: [103.79, 25.51],烟台: [121.39, 37.52],福州: [119.3, 26.08],瓦房店: [121.979603, 39.627114],即墨: [120.45, 36.38],抚顺: [123.97, 41.97],玉溪: [102.52, 24.35],张家口: [114.87, 40.82],阳泉: [113.57, 37.85],莱州: [119.942327, 37.177017],湖州: [120.1, 30.86],汕头: [116.69, 23.39],昆山: [120.95, 31.39],宁波: [121.56, 29.86],湛江: [110.359377, 21.270708],揭阳: [116.35, 23.55],荣成: [122.41, 37.16],连云港: [119.16, 34.59],葫芦岛: [120.836932, 40.711052],常熟: [120.74, 31.64],东莞: [113.75, 23.04],河源: [114.68, 23.73],淮安: [119.15, 33.5],泰州: [119.9, 32.49],南宁: [108.33, 22.84],营口: [122.18, 40.65],惠州: [114.4, 23.09],江阴: [120.26, 31.91],蓬莱: [120.75, 37.8],韶关: [113.62, 24.84],嘉峪关: [98.289152, 39.77313],广州: [113.23, 23.16],延安: [109.47, 36.6],太原: [112.53, 37.87],清远: [113.01, 23.7],中山: [113.38, 22.52],昆明: [102.73, 25.04],寿光: [118.73, 36.86],盘锦: [122.070714, 41.119997],长治: [113.08, 36.18],深圳: [114.07, 22.62],珠海: [113.52, 22.3],宿迁: [118.3, 33.96],咸阳: [108.72, 34.36],铜川: [109.11, 35.09],平度: [119.97, 36.77],佛山: [113.11, 23.05],海口: [110.35, 20.02],江门: [113.06, 22.61],章丘: [117.53, 36.72],肇庆: [112.44, 23.05],大连: [121.62, 38.92],临汾: [111.5, 36.08],吴江: [120.63, 31.16],石嘴山: [106.39, 39.04],沈阳: [123.38, 41.8],苏州: [120.62, 31.32],茂名: [110.88, 21.68],嘉兴: [120.76, 30.77],长春: [125.35, 43.88],胶州: [120.03336, 36.264622],银川: [106.27, 38.47],张家港: [120.555821, 31.875428],三门峡: [111.19, 34.76],锦州: [121.15, 41.13],南昌: [115.89, 28.68],柳州: [109.4, 24.33],三亚: [109.511909, 18.252847],自贡: [104.778442, 29.33903],吉林: [126.57, 43.87],阳江: [111.95, 21.85],泸州: [105.39, 28.91],西宁: [101.74, 36.56],宜宾: [104.56, 29.77],呼和浩特: [111.65, 40.82],成都: [104.06, 30.67],大同: [113.3, 40.12],镇江: [119.44, 32.2],桂林: [110.28, 25.29],张家界: [110.479191, 29.117096],宜兴: [119.82, 31.36],北海: [109.12, 21.49],西安: [108.95, 34.27],金坛: [119.56, 31.74],东营: [118.49, 37.46],牡丹江: [129.58, 44.6],遵义: [106.9, 27.7],绍兴: [120.58, 30.01],扬州: [119.42, 32.39],常州: [119.95, 31.79],潍坊: [119.1, 36.62],重庆: [106.54, 29.59],台州: [121.420757, 28.656386],南京: [118.78, 32.04],滨州: [118.03, 37.36],贵阳: [106.71, 26.57],无锡: [120.29, 31.59],本溪: [123.73, 41.3],克拉玛依: [84.77, 45.59],渭南: [109.5, 34.52],马鞍山: [118.48, 31.56],宝鸡: [107.15, 34.38],焦作: [113.21, 35.24],句容: [119.16, 31.95],北京: [116.46, 39.92],徐州: [117.2, 34.26],衡水: [115.72, 37.72],包头: [110, 40.58],绵阳: [104.73, 31.48],乌鲁木齐: [87.68, 43.77],枣庄: [117.57, 34.86],杭州: [120.19, 30.26],淄博: [118.05, 36.78],鞍山: [122.85, 41.12],溧阳: [119.48, 31.43],库尔勒: [86.06, 41.68],安阳: [114.35, 36.1],开封: [114.35, 34.79],济南: [117, 36.65],德阳: [104.37, 31.13],温州: [120.65, 28.01],九江: [115.97, 29.71],邯郸: [114.47, 36.6],临安: [119.72, 30.23],兰州: [103.73, 36.03],沧州: [116.83, 38.33],临沂: [118.35, 35.05],南充: [106.110698, 30.837793],天津: [117.2, 39.13],富阳: [119.95, 30.07],泰安: [117.13, 36.18],诸暨: [120.23, 29.71],郑州: [113.65, 34.76],哈尔滨: [126.63, 45.75],聊城: [115.97, 36.45],芜湖: [118.38, 31.33],唐山: [118.02, 39.63],平顶山: [113.29, 33.75],邢台: [114.48, 37.05],德州: [116.29, 37.45],济宁: [116.59, 35.38],荆州: [112.239741, 30.335165],宜昌: [111.3, 30.7],义乌: [120.06, 29.32],丽水: [119.92, 28.45],洛阳: [112.44, 34.7],秦皇岛: [119.57, 39.95],株洲: [113.16, 27.83],石家庄: [114.48, 38.03],莱芜: [117.67, 36.19],常德: [111.69, 29.05],保定: [115.48, 38.85],湘潭: [112.91, 27.87],金华: [119.64, 29.12],岳阳: [113.09, 29.37],长沙: [113, 28.21],衢州: [118.88, 28.97],廊坊: [116.7, 39.53],菏泽: [115.480656, 35.23375],合肥: [117.27, 31.86],武汉: [114.31, 30.52],大庆: [125.03, 46.58],};const convertData = function (data) {var res = [];for (var i = 0;

这样你就可以得到一个地图啦

注：如果你想要去掉这样渲染出来的地图下方的百度地图logo，你可以直接在css中添加如下样式：

.anchorBL {display: none;}

做完上面所有你就可以得到一个地图啦，echarts官方也有示例说明：
