jpgraph help

[Gazz1982]

I have managed to create a graph plot but no bars are being displayed, im not sure what i have done wrong - is it to do with the jpgraph.php and jpgraph_bar.php location?

 

 

heres the code

<?php
include ("E:/web/jpgraph-1.21b/src/jpgraph.php");    
include ("E:/web/jpgraph-1.21b/src/jpgraph_bar.php"); 
// Connecting, selecting database
$db = mysql_connect('127.0.0.1', 'root', '') or die(mysql_error()); 
mysql_select_db("gary",$db) or die(mysql_error()); 

// Performing SQL query

$query = "SELECT count(*) FROM answer";

$result = mysql_query($query) or die('Query failed: ' . mysql_error());

while($row = mysql_fetch_array($result, MYSQL_ASSOC)) 
{ 
$data[] = $row[1]; 
$leg[] = $row[0]; 
} 

$graph = new Graph(550,550,"auto"); 
$graph->SetScale("textint"); 
$graph->img->SetMargin(50,30,50,50); 
//$graph->AdjBackgroundImage(0.4,0.7,-1); //setting BG type 
//$graph->SetBackgroundImage("linux_pez.png",BGIMG_FILLFRAME); //adding image 
//$graph->SetShadow(); 

$graph->xaxis->SetTickLabels($leg);

$bplot = new BarPlot($data); 
$bplot->SetFillColor("lightgreen"); // Fill color 
$bplot->value->Show(); 
$bplot->value->SetFont(FF_ARIAL,FS_BOLD); 
$bplot->value->SetAngle(45); 
$bplot->value->SetColor("black","navy"); 

$graph->Add($bplot); 
$graph->Stroke();


// Closing connection
mysql_close($link);
?>
