菜鸟提问：jpgraph的路径问题.

 
  if(extension_loaded("gd")) {  
 echo "可以使用gd
";  
 foreach(gd_info() as $cate=>$value)  
     echo "$cate: $value
";;  
 }else  
 echo "‘没安装gd扩展’";  
 ?>  
  
    require_once ('jpgraph/jpgraph.php');  
 require_once ('jpgraph/jpgraph_bar.php');  
  
 $datay=array(62,105,85,50);  
  
  
 // Create the graph. These two calls are always required  
 $graph = new Graph(350,220,'auto');  
 $graph->SetScale("textlin");  
  
 //$theme_class="DefaultTheme";  
 //$graph->SetTheme(new $theme_class());  
  
 // set major and minor tick positions manually  
 $graph->yaxis->SetTickPositions(array(0,30,60,90,120,150), array(15,45,75,105,135));  
 $graph->SetBox(false);  
  
 //$graph->ygrid->SetColor('gray');  
 $graph->ygrid->SetFill(false);  
 $graph->xaxis->SetTickLabels(array('A','B','C','D'));  
 $graph->yaxis->HideLine(false);  
 $graph->yaxis->HideTicks(false,false);  
  
 // Create the bar plots  
 $b1plot = new BarPlot($datay);  
  
 // ...and add it to the graPH  
 $graph->Add($b1plot);  
  
  
 $b1plot->SetColor("white");  
 $b1plot->SetFillGradient("#4B0082","white",GRAD_LEFT_REFLECTION);  
 $b1plot->SetWidth(45);  
 $graph->title->Set("Bar Gradient(Left reflection)");  
  
 // Display the graph  
 $graph->Stroke();  
 ?>  
  结果如下：
 可以使用gd

 因为把jpgraph的文件夹解压缩到easyphp\php\php546里了，所以php.ini没有修改.可是出现了问题，不知道这么回事.如果需要修改php.ini，请问要如何写呢？谢谢各位大神的回答.

  把 jpgraph 文件夹的全路径附加到 include_path 后面
