  • Html5绘制饼图统计图

    这里要介绍的是一个jQuery插件:jquery.easysector.js

    Html5提供了强大的绘图API,让我们能够使用javascript轻松绘制各种图形。本文将主要讲解使用HTML5绘制饼图(统计图)的方法。先看一下饼图效果:

    http://hovertree.com/texiao/easysector/

    jquery.easysector.js

    这个图是动态生成的,根据传入的比例参数(数组),来动态绘制饼图。饼图的大小也是根据<canvas>高度来动态调整的。

    使用easysector插件的办法:

    引用jquery库与jquery.easysector.js,在页面中防止一个div(例如:<div id="easysector"></div>)

    然后使用js数组构造各项数据,然后执行easysector()方法,参数就是构造的数组与名称大小等项。

    全部代码如下:

    <!DOCTYPE html>
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
        <title>EasySector - HoverTree</title><base target="_blank" />
        <meta charset="utf-8" />
