// Dataset definition
$DataSet = new pData;
$DataSet->AddPoint(array(100,320,200,10,43),"Serie1");

 // Initialise the graph
 $Test = new pChart(500,200);
 $Test->setFontProperties("Fonts/tahoma.ttf",8);
 $Test->drawFilledRoundedRectangle(7,7,293,193,5,240,240,240);
 $Test->drawRoundedRectangle(5,5,295,195,5,230,230,230);
 // Draw the pie chart
 $Test->AntialiasQuality = 0;
 $Test->setShadowProperties(2,2,200,200,200);
 $Test->drawFlatPieGraphWithShadow($DataSet->GetData(),$DataSet->GetDataDescription(),120,100,60,PIE_PERCENTAGE,8);
 $Test->clearShadow();
 $Test->drawPieLegend(230,15,$DataSet->GetData(),$DataSet->GetDataDescription(),250,250,250);
 $imageFile = 'example12.png';
 $Test->Render($imageFile);
echo '';
