主要包括三个文件：

1、view.php是调用程序。

2、chart.php是用来生成图表的程序。

3、gbtoutf8.php是用来中文解码的（注：已解决中英文混合不能正常显示的问题）

1、view.php

include("gbtoutf8.php");

$aHard = gb2utf8("地板,窗户,玻璃,桌子,灯管,植被");

$title1 = gb2utf8('2002年IT维护report');

$title2 = gb2utf8('2002年软件维护report');

$title3 = gb2utf8('2002年固定资产report');

?>

2、chart.php
