1、打开ECharts网站
输入网址：/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 （）',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: '新疆',value: randomData() },{name: '江苏',value: randomData() }, {name: '浙江',value: randomData() },{name: '江西',value: randomData() }, {name: '湖北',value: randomData() },{name: '广西',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() }, {name: '海南',value: randomData() },{name: '台湾',value: randomData() }, {name: '香港',value: randomData() },{name: '澳门',value: randomData() } ]}]};
3、中国地图数据可视化效果
