create-react-app 结合百度地图和Echarts3.0迁徙图
一、创建create-react-app脚手架
npm install -g create-react-app
create-react-app my-app /* 去目录中创建项目，my-app为项目名称 */
cd myapp /* 进入目录，然后启动 */
npm start
二、添加echarts模块
npm install echarts --save
三、项目 index.html中引入百度API的Key
React App
四、添加EchartsMinigrate组件并引入各个模块
import React, { Component } from 'react';
//引入echarts主模块
import echarts from 'echarts/lib/echarts';
import Bmap from 'echarts/extension/bmap/bmap';
import 'echarts/map/js/china';
//引入地图和柱状图
import 'echarts/lib/chart/map';
import 'echarts/lib/chart/bar';
// 引入提示框和标题组件
import 'echarts/lib/component/tooltip';
import 'echarts/lib/component/title';
class EchartsMinigrate extends Component{
componentDidMount() {
this.minigratecharts()
};
minigratecharts(){
var myChart = echarts.init(document.getElementById('main'));
