1,新建静态页面demo.html,引入百度echarts库,在这里我引入的是网络库

<!-- V型知识库 www.vxzsk.com 原创-->
 <script type="text/javascript" src="http://echarts.baidu.com/gallery/vendors/echarts/echarts-all-3.js"></script>

2,热力图容器html代码,只需一行html代码,在<body></body>之间

<div id="container" style="height: 500px"></div>

在这里呢,我设置的div高度为500px,宽带自适应,读者可根据自身业务调整

3,javascript实现代码

<script type="text/javascript">
var dom = document.getElementById("container");
var myChart = echarts.init(dom);
var app = {};
app.title = '笛卡尔坐标系上的热力图';

        '6p', '7p', '8p', '9p', '10p', '11p'];
var days = ['Saturday', 'Friday', 'Thursday',
        'Wednesday', 'Tuesday', 'Monday', 'Sunday'];

var data = [[0,0,5],[0,1,1],[0,2,0],[0,3,0],[0,4,0],[0,5,0],[0,6,0],[0,7,0],[0,8,0],[0,9,0],[0,10,0],[0,11,2],[0,12,4],[0,13,1],[0,14,1],[0,15,3],[0,16,4],[0,17,6],[0,18,4],[0,19,4],[0,20,3],[0,21,3],[0,22,2],[0,23,5],[1,0,7],[1,1,0],[1,2,0],[1,3,0],[1,4,0],[1,5,0],[1,6,0],[1,7,0],[1,8,0],[1,9,0],[1,10,5],[1,11,2],[1,12,2],[1,13,6],[1,14,9],[1,15,11],[1,16,6],[1,17,7],[1,18,8],[1,19,12],[1,20,5],[1,21,5],[1,22,7],[1,23,2],[2,0,1],[2,1,1],[2,2,0],[2,3,0],[2,4,0],[2,5,0],[2,6,0],[2,7,0],[2,8,0],[2,9,0],[2,10,3],[2,11,2],[2,12,1],[2,13,9],[2,14,8],[2,15,10],[2,16,6],[2,17,5],[2,18,5],[2,19,5],[2,20,7],[2,21,4],[2,22,2],[2,23,4],[3,0,7],[3,1,3],[3,2,0],[3,3,0],[3,4,0],[3,5,0],[3,6,0],[3,7,0],[3,8,1],[3,9,0],[3,10,5],[3,11,4],[3,12,7],[3,13,14],[3,14,13],[3,15,12],[3,16,9],[3,17,5],[3,18,5],[3,19,10],[3,20,6],[3,21,4],[3,22,4],[3,23,1],[4,0,1],[4,1,3],[4,2,0],[4,3,0],[4,4,0],[4,5,1],[4,6,0],[4,7,0],[4,8,0],[4,9,2],[4,10,4],[4,11,4],[4,12,2],[4,13,4],[4,14,4],[4,15,14],[4,16,12],[4,17,1],[4,18,8],[4,19,5],[4,20,3],[4,21,7],[4,22,3],[4,23,0],[5,0,2],[5,1,1],[5,2,0],[5,3,3],[5,4,0],[5,5,0],[5,6,0],[5,7,0],[5,8,2],[5,9,0],[5,10,4],[5,11,1],[5,12,5],[5,13,10],[5,14,5],[5,15,7],[5,16,11],[5,17,6],[5,18,0],[5,19,5],[5,20,3],[5,21,4],[5,22,2],[5,23,0],[6,0,1],[6,1,0],[6,2,0],[6,3,0],[6,4,0],[6,5,0],[6,6,0],[6,7,0],[6,8,0],[6,9,0],[6,10,1],[6,11,0],[6,12,2],[6,13,1],[6,14,3],[6,15,4],[6,16,0],[6,17,0],[6,18,0],[6,19,0],[6,20,1],[6,21,2],[6,22,2],[6,23,6]];

4,用浏览器打开demo.html,效果如下

如上图所示,热力图已经显示出来了,关于热力图各个参数属性,请前往百度echarts官方文档查阅,在这里不在详述。

5,热力图demo.html完整代码
