react使用echcharts地图

首先安装echarts,echarts-for-react

如下:

map.js:


import React, { Component } from 'react';
import EchartsReact from "echarts-for-react"
import "echarts/map/js/china"
class ChinaMap extends Component{
    // eslint-disable-next-line no-useless-constructor
    constructor(props,content){
        super(props,content)
    }
    render(){
        var option = {
            title : {
                text: '今日地区交易统计',
                subtext: '数据来自途比',
                textStyle:{
                    color:"#fff"
                },
                x:'center'
            },
            tooltip : {
            },
            legend: {
                orient: 'vertical',
                x:'left',
                data:['交易量']
            },
            dataRange: {
                x: 'left',
                y: 'center',
                splitList: [

                    ],
                    textStyle: {
                    color: '#3899FF' // 值域文字颜色
                    }
