1、打开ECharts网站

输入网址：https://echarts.apache.org/examples/zh/editor.html?c=map-china&theme=light

2、将左则的内容调整成

function randomData() {   return Math.round(Math.random()*500);  } 

option = {
    tooltip: {
        trigger: 'item',
        formatter: '{b}'
    },
    title: {
            text: '中国地图人口密度 （2011）',
            subtext: '人口密度数据来自Wikipedia',
            sublink: '来自：dadicn'
        },
        tooltip: {
            trigger: 'item',
            formatter: '{b}<br/>{c} (p / km2)'
        },
        toolbox: {
            show: true,
            orient: 'vertical',
            left: 'right',
            top: 'center',
            feature: {
                dataView: {readOnly: false},
                restore: {},
                saveAsImage: {}
            }
        },
        visualMap: {
            min: 0,
            max: 500,
            text: ['High', 'Low'],
            realtime: false,
            calculable: true,
            inRange: {
                color: ['lightskyblue', 'yellow', 'orangered']
            }
        },
    series: [
        {
            name: '中国',
            type: 'map',
            mapType: 'china',
            selectedMode: 'multiple',
            label: {
                show: true
            },
            data: [
                {name: '北京',value: '100' },{name: '天津',value: randomData() },  
                {name: '上海',value: randomData() },{name: '重庆',value: randomData() },  
                {name: '河北',value: randomData() },{name: '河南',value: randomData() },  
                {name: '云南',value: randomData() },{name: '辽宁',value: randomData() },  
                {name: '黑龙江',value: randomData() },{name: '湖南',value: randomData() },  
                {name: '安徽',value: randomData() },{name: '山东',value: randomData() },

                {name: '甘肃',value: randomData() },{name: '山西',value: randomData() },  
                {name: '内蒙古',value: randomData() },{name: '陕西',value: randomData() },  
                {name: '吉林',value: randomData() },{name: '福建',value: randomData() },  
                {name: '贵州',value: randomData() },{name: '广东',value: randomData() },  
                {name: '青海',value: randomData() },{name: '西藏',value: randomData() },  
                {name: '四川',value: randomData() },{name: '宁夏',value: randomData() },
