 /* Library settings */ 
 define("CLASS_PATH", "../../../class"); 
 define("FONT_PATH", "../../../fonts"); 

 /* pChart library inclusions */ 

 /* Create and populate the pData object */ 
 $MyData = new pData();   
 $MyData->addPoints(array(150,220,300,250,420,200,300,200,100),"Server A"); 
 $MyData->addPoints(array(140,VOID,340,300,320,300,200,100,50),"Server B"); 

 /* Create the pChart object */ 
 $myPicture = new pImage(700,230,$MyData); 

 /* Retrieve the image map */ 
 if (isset($_GET["ImageMap"]) || isset($_POST["ImageMap"])) 
 /* Set the image map name */ 
 /* Turn of Antialiasing */ 
 $myPicture->Antialias = FALSE;

 $Settings = array("R"=>170, "G"=>183, "B"=>87, "Dash"=>1, "DashR"=>190, "DashG"=>203, "DashB"=>107);

 /* Overlay with a gradient */ 
 $Settings = array("StartR"=>219, "StartG"=>231, "StartB"=>139, "EndR"=>1, "EndG"=>138, "EndB"=>68, "Alpha"=>50);

 /* Add a border to the picture */
