天地圖結合echarts效果糟糕,體驗極差，建議直接放棄。

import * as echarts from 'echarts'; require('echarts-extension-tmap') import './syless.css'; var option = { tmap: { // 天地圖中心經緯度 center: this.center, // 天地圖縮放 zoom: this.zoom, // 拖拽 roam: false, // 天地圖自定義樣式 只有 默認、black、indigo三種樣式 mapStyle: 'indigo' }, series: [ { name: '投資指數', type: 'scatter', coordinateSystem: 'tmap', } ] }; // 初始化ECharts var chart = echarts.init(document.getElementById('echarts-amap')); chart.setOption(option);

主要文件代碼，key用自己的.
webpack剛開始學，寫的垃圾還望海含，下面是遇到的錯誤和借鑒的文檔。有條件的自己搭一份吧。
echarts-extension-tmap
這個插件可以在npm中找到，但是因為里面使用require()引入，所以在cdn中找到的靜態資源我一直報沒有require這個方法或者未定義。
考慮到報錯原因我決定采用webpack來解決require的導入問題。
然后又遇到 can't resolve T from 'T'
T是外部window下有的方法，他內部確實沒有，全局定義存在。
然后配置一下package.json
module.exports = { //... externals: { T: 'T', }, };
https://webpack.docschina.org/configuration/externals/這個是webpack對於外部擴展的解釋
https://blog.csdn.net/seanxwq/article/details/79240937這個是博主的解釋
然后這里借鑒這位博客的高德地圖使用案列
https://www.cnblogs.com/plainheart/p/how-to-use-echarts-to-display-data-visualization-on-amap.html
echarts-extension-amap里也有超詳細案例和解釋。
