我想用php创建图形。我测试了jpgraph的例子。但它显示错误 像

<?php
include('phpgraphlib.php');
$graph = new PHPGraphLib(500,350);
$data = array(12124, 5535, 43373, 22223, 90432, 23332, 15544, 24523,
32778, 38878, 28787, 33243, 34832, 32302);
$graph->addData($data);
$graph->setTitle('Widgets Produced');
$graph->setGradient('red', 'maroon');
$graph->createGraph();
?>

(你也应该配置php来启用图像创建) 在Windows中,您将包含GD2 DLL php_gd2.dll作为php.ini中的扩展。在PHP 4.3.2中删除了GD1 DLL php_gd.dll。另请注意,首选的真彩色图像函数,例如imagecreatetruecolor(),需要GD2。
