再介绍一下我自己，呵呵
我是个新手，当时学php纯粹是为了应付领导哦，让我们做统计图，我本来是学asp的，突然改行很不适应，不过php功能的确很强大呀，呵呵，我都离不了他了，这不，饼图，柱型图都搞定了，可是还有很多问题我不会，还希望大家多指教呀，说了好多废话了，我还以为是在写信那
我的联系方式是：

老板催了，没办法，饼图函数出炉了，大家快抢呀

函数说明
$chartdata:数据，是数组元素
$chartfont:字号
$chartdiameter:决定饼的大小（要看你饿不饿了，呵呵）
$chartlabel:标题，也是数组元素
$colorslice:颜色数组，例如$
tmp
=
array
255,255,255);$colorslic=array($tmp);
$colorborder:边框颜色，数组
$colortext:文本颜色,数组
$colorbody:背景颜色，数组
$file:输出图片文件名*/
