PHP能实现这样的效果吗？？

Question

可以的，给你一个使用GDIMAGE函数的例子，绘制一个动态曲线。
<?php  
Header("Content-type:  image/gif");  
$im  =  imagecreate(400,30);  
$black  =  ImageColorAllocate($im,  0,0,0);  
$white  =  ImageColorAllocate($im,  255,255,255);  
imageline($im,  1,  1,  350,  25,  $black);  
imagearc($im,  200,  15,  20,  20,  35,  190,  $white);  
imagestring($im,  5,  4,  10,  "Graph  TEST!!",  $white);  
ImageGif($im);  
ImageDestroy($im);  
?>  

Answer 1

用gd做一个曲线图就可以了，我可以给你一个类，让你研究一下：图类，可显示多种图形
<?//图类
