篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了ECharts 3.0 初学感想及学习中遇到的瓶颈相关的知识，希望对你有一定的参考价值。
因为刚工作的原因，压力特别大，加上时间也不是很充足，所以最近也没怎么整理学习的东西，今天趁着手头工作完成总结一下吧，
说实话，其实ECharts 就是图表绚丽，展示数据渲染效果更加强烈，从2.0到3.0做得更加精致，不多比比，正题
首先你想使用必须要引入js/json文件 ，最主要的文件是 echarts.js 这个可以到官网下载完整版就好：http://echarts.baidu.com/download.html
之后直接在页面引用就可以，要注意存放路径，要用 UTF-8 编码
<script src="echartsmain.js"></script>
饼图/柱图这些就不说了，因为boss给的任务是地图，就直接说地图吧
接下来要引入地图文件，我用的是js格式，当然也可以引入json格式，
这里先说一下地图从哪里下载：http://echarts.baidu.com/download-map.html
js格式导入（这里我用的是山东省的，并不需要引入全国的）
<!-- <script src="china.js"></script> --> <script src="shandong1.js"></script>
json格式的引入
<script type="text/javascript"> //function(省份拼音+Json) $.get(\'map/json/china.json\', function(gansuJson) { //echarts.registerMap(\'省份汉语名称\', 省份拼音+Json); echarts.registerMap(\'甘肃\', gansuJson); var chart = echarts.init(document.getElementById(\'main\')); chart.setOption({ series : [ { type : \'map\', //map的值也是，省份汉语名称 map : \'甘肃\' } ] }); }); <script>
要想有地方把图表/地图展示出来，那肯定要有地方来呈现吧，定义一个dom
<div id="main" style="width: 40%;height:400px;float:left;"></div>
这里 id 是啥其实无所谓的，只是官网（http://echarts.baidu.com/index.html）用的这个 main ，看完教程（http://echarts.baidu.com/tutorial.html）后，
就觉得还是 main 更舒服一点
基于准备好的dom，初始化echarts实例
var myChart = echarts.init(document.getElementById(\'main\'));
还有一点要注意的地方
在option设置对应的map属性：中国地图用china/省市地图直接用汉语,如山东省用山东
其他的就没有什么要特别注意的地方了，下面是代码
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <%@ include file="/framework/include/pageset.jspa"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <title>跳转页面</title> <script src="echartsmain.js"></script> <!-- <script src="china.js"></script> --> <script src="shandong1.js"></script> </head> <body> <!-- 为ECharts准备一个具备大小（宽高）的Dom --> <div id="main" style="width: 40%;height:400px;float:left;"></div> <!-- IFRAME 窗体引入 --> <!-- <IFRAME NAME="content_frame" width=59%; height=400px; SRC="air/doc/example/air.html" ></IFRAME> <IFRAME NAME="content_frame" width=25%; height=360px; SRC="index4.html" ></IFRAME> <IFRAME NAME="content_frame" width=24%; height=360px; SRC="index4.html" ></IFRAME> <IFRAME NAME="content_frame" width=24%; height=360px; SRC="index4.html" ></IFRAME> <IFRAME NAME="content_frame" width=24%; height=360px; SRC="index4.html" ></IFRAME> --> <!-- 1.首先引入要用的js/json文件 2.在option设置对应的map属性：中国地图用china/省市地图直接用汉语,如山东省用山东 3.定义一个Map来容纳城市坐标 //还有很多目前没有搞明白 <- 存在问题 -> 1.城市名称不显示 2.背景单调不绚丽 <- 个性化 -> 1.如果地图上结合其他图表/地图效果 --> <script type="text/javascript"> // 基于准备好的dom，初始化echarts实例 var myChart = echarts.init(document.getElementById(\'main\'));
