一、概述

首先ECharts 是一個使用 JavaScript 實現(xiàn)的開源可視化庫。兼容當(dāng)前絕大部分瀏覽器，而且提供大量可交互、可高度個性化定制的圖表，滿足開發(fā)者各種需求。
今天主要展示echarts地圖功能。echarts內(nèi)置了世界地圖、中國及各個省市自治區(qū)地圖數(shù)據(jù)，可通過標準GeoJson擴展地圖類型。

二、Echart實現(xiàn)中國地圖

先看實現(xiàn)效果

實現(xiàn)步驟

1、首先要提供一個容器，并給定大小

<div class="wrapper"><div class="map-container" id="main"></div></div> .map-container{width: 500px;height: 500px;}

2、引入echart.js和china.js(中國地圖的js數(shù)據(jù))

echart.js可以在echarts官網(wǎng)中下載到，china.js官方已經(jīng)不提供了，需要自己去找。
這些js文件我發(fā)布在了csdn資源上傳目錄，下載需要5積分，找資源不易，需要的可以自行去取！

<script src="js/echarts.js"></script><script src="js/china.js"></script>

3、實例化echarts對象

// 基于準備好的dom，初始化echarts實例var myChart = echarts.init(document.getElementById('main'));

4、參數(shù)設(shè)置，因為項目需求需要添加陰影和單獨設(shè)置地圖邊框，所以實際上是2張地圖重疊，下面那張地圖做陰影和邊框處理。

// 指定圖表的配置項和數(shù)據(jù)var option = {tooltip: {show: false},geo: {map: "china",roam: false,// 一定要關(guān)閉拖拽zoom: 1.23,center: [105, 36], // 調(diào)整地圖位置label: {normal: {show: false, //關(guān)閉省份名展示fontSize: "10",color: "rgba(0,0,0,0.7)"},emphasis: {show: false}},itemStyle: {normal: {areaColor: "#0d0059",borderColor: "#389dff",borderWidth: 1, //設(shè)置外層邊框shadowBlur: 5,shadowOffsetY: 8,shadowOffsetX: 0,shadowColor: "#01012a"},emphasis: {areaColor: "#184cff",shadowOffsetX: 0,shadowOffsetY: 0,shadowBlur: 5,borderWidth: 0,shadowColor: "rgba(0, 0, 0, 0.5)"}}},series: [{type: "map",map: "china",roam: false,zoom: 1.23,center: [105, 36],// geoIndex: 1,// aspectScale: 0.75, //長寬比showLegendSymbol: false, // 存在legend時顯示label: {normal: {show: false},emphasis: {show: false,textStyle: {color: "#fff"}}},itemStyle: {normal: {areaColor: "#0d0059",borderColor: "#389dff",borderWidth: 0.5},emphasis: {areaColor: "#17008d",shadowOffsetX: 0,shadowOffsetY: 0,shadowBlur: 5,borderWidth: 0,shadowColor: "rgba(0, 0, 0, 0.5)"}}}]};// 使用剛指定的配置項和數(shù)據(jù)顯示圖表。myChart.setOption(option);

5、添加散點數(shù)據(jù)，這里注意要把上面設(shè)置過的地圖帶上，之前設(shè)置的series的數(shù)據(jù)會被覆蓋掉。

var dataValue = dealWithData();var data1 = dataValue.splice(0, 6);var option = {series: [{type: "map",map: "china",roam: false,zoom: 1.23,center: [105, 36],// geoIndex: 1,// aspectScale: 0.75, //長寬比showLegendSymbol: false, // 存在legend時顯示label: {normal: {show: false},emphasis: {show: false}},itemStyle: {normal: {areaColor: "#0d0059",borderColor: "#389dff",borderWidth: 0.5},emphasis: {areaColor: "#17008d",shadowOffsetX: 0,shadowOffsetY: 0,shadowBlur: 5,borderWidth: 0,shadowColor: "rgba(0, 0, 0, 0.5)"}}},{name: "",type: "scatter",coordinateSystem: "geo",data: dataValue,// symbolSize: function(val) {// return val[2] / 10;// },symbol: "circle",symbolSize: 8,hoverSymbolSize: 10,tooltip: {formatter(value) {return value.data.name + "<br/>" + "物流量：" + "22";},show: true},encode: {value: 2},label: {formatter: "{b}",position: "right",show: false},itemStyle: {color: "#0efacc"},emphasis: {label: {show: false}}},{name: "Top 5",type: "effectScatter",coordinateSystem: "geo",data: data1,symbolSize: 15,tooltip: {show: false},encode: {value: 2},showEffectOn: "render",rippleEffect: {brushType: "stroke",color: "#0efacc",period: 9,scale: 5},hoverAnimation: true,label: {formatter: "{b}",position: "right",show: true},itemStyle: {color: "#0efacc",shadowBlur: 2,shadowColor: "#333"},zlevel: 1}]};myChart.setOption(option);

6、測試數(shù)據(jù)的方法，需要的可以復(fù)制使用
