利用PHPExcel转Excel饼图

PHPExcel处理Excel档真是个强大的工具，我有张报表，带饼图，需要转成Excel, PHPExcel有一个相关的例子，参考并修改后实现了这个效果，

可以让用户在点击下载过程中生成和下载Excel档，并在Excel中档生成饼图。

对其例子主要做了两方面的修改：

1. 改成从MySQL数据库取资料

2. 加上了中文文件名在部份浏览器，如IE下，下载时名字乱码的解决方法.

PHP报表如下:

代码如下:

另要注意的地方是，Excel的饼图，通过指定其标签，值所对应的单元格范围，自动生成，所以主要是在代码中计算好。另在非Windows服务器，生成会失败。
