echarts实现伪3D地图、省会坐标涟漪、自动轮播、数据联动

本文主要是介绍echarts实现伪3D地图、省会坐标涟漪、自动轮播、数据联动，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

效果图：

实现的效果：

1. 伪3D效果地图
2. 省会坐标展示标点，并带有涟漪效果
3. 鼠标覆盖的区域，区域以及涟漪高亮
4. 地图上的所有区域按照时间间隔轮播
5. 点击、轮播时的区域，会带着所有其他表格的数据进行联动刷新，展示不同地区的统计数据

完整的JS代码：

let regions = [];
let orgRegions = [];// 初始状态颜色
var selectedAreaName = "";// 当前被选中/轮播地市
var mapName = 'NX';
var geoJson = mapData;// 普通涟漪效果的标点
function convertNormalLianyiData(mapData) {var res = [];for (var i = 0; i < mapData.features.length; i++) {var prop = mapData.features[i].properties;//var geoCoord =  prop.center;// 标点位于地区省会var geoCoord = prop.centroid;// 标点位于地区正中心if (geoCoord && prop.name != selectedAreaName) {res.push({name: prop.name,// 横纵坐标后，拼接高度坐标，默认为10value: geoCoord.concat(100),adcode: prop.adcode,});}}return res;
}
// 选中区域涟漪效果的标点
function convertSelectedLianyiData(mapData) {var res = [];for (var i = 0; i < mapData.features.length; i++) {var prop = mapData.features[i].properties;//var geoCoord =  prop.center;// 标点位于地区省会var geoCoord = prop.centroid;// 标点位于地区正中心if (geoCoord && prop.name == selectedAreaName) {res.push({name: prop.name,// 横纵坐标后，拼接高度坐标，默认为10value: geoCoord.concat(100),adcode: prop.adcode,});}}return res;
}for (i = 0; i < geoJson.features.length; i++) {let cityInfo = {name: geoJson.features[i].properties.name,adcode: geoJson.features[i].properties.adcode,}city.push(cityInfo);
}
for (i = 0; i < city.length; i++) {regions.push({name: city[i].name,adcode: city[i].adcode,itemStyle: {color: color[i % 10]},});orgRegions.push({name: city[i].name,adcode: city[i].adcode,itemStyle: {color: color[i % 10]},});
