php GD库生成的图形类，可以用来制作报表之用，参数都比较简单。

<?php //图类

var $G;//...G. 
var $B;//...B. 
var $TRANSPARENT;//是否透明1或0 
var $IMAGE;//图片对像 
//------------------- 
var $ARRAYSPLIT;//指定用于分隔数值的符号 
var $ITEMARRAY;//数值 
var $REPORTTYPE;//图表类型,1为竖柱形2为横柱形3为折线形 
var $BORDER;//距离 
//------------------- 
var $FONTSIZE;//字体大小 
var $FONTCOLOR;//字体颜色

var $numX = 1;//X轴起始刻度值 
var $stepX = 1;//X轴每一个刻度间隔值
