我运行自带的例子为什么不显示图表?而是显示的这些东西呢?
原代码如下:

require_once('../lib/OFC/OFC_Chart.php');
$title = new OFC_Elements_Title( date("D M d Y") );
$bar = new OFC_Charts_Bar_Glass();
$bar->set_values( array(9,8,7,6,5,4,3,2,1) );
$chart = new OFC_Chart();
$chart->set_title( $title );
$chart->add_element( $bar );
echo $chart->toString();
?>
显示结果:
{"title":{"text":"Tue Apr 17 2012"},"elements":[{"type":"bar_glass","values":[9,8,7,6,5,4,3,2,1]}]}
请问有大虾知道吗?急,在线等。谢谢!
------解决方案--------------------
echo gmdate('H:i:s', abs(strtotime('2012-04-17 17:43:09') - strtotime('2012-04-17 18:01:02')));

沉下心来,认真思考
