Problem med JpGraph

Hej

Nogen der kan hjælpe med dette?

Jeg har installeret GD lib, og lagt jpgraph pakken/biblioteket under c:/PHP/ext (win2k server)

Jeg har så kopieret de 3 includede filer i nedenstående til samme dir som mit projekt, men jeg får ikke tegnet nogen graf - siden er bare blank?


<?php
include ("jpgraph.php");
include ("jpgraph_pie.php");
include ("jpgraph_pie3d.php");

// Some data
$data = array(20,27,45,75,90);

// Create the Pie Graph.
$graph = new PieGraph(350,200,"auto");
$graph->SetShadow();

// Set A title for the plot
$graph->title->Set("Example 1 3D Pie plot");
$graph->title->SetFont(FF_VERDANA,FS_BOLD,18);
$graph->title->SetColor("darkblue");
$graph->legend->Pos(0.1,0.2);

// Create pie plot
$p1 = new PiePlot3d($data);
$p1->SetTheme("sand");
$p1->SetCenter(0.4);
$p1->SetAngle(30);
$p1->value->SetFont(FF_ARIAL,FS_NORMAL,12);
$p1->SetLegends(array("Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct"));

$graph->Add($p1);
$graph->Stroke();
