This is code i wrote in the controller:
App::import('Vendor', 'PdataClass', array('file' => 'pchart/class' . DS . 'pData.class.php'));
App::import('Vendor', 'PdrawClass', array('file' => 'pchart/class' . DS . 'pDraw.class.php'));
App::import('Vendor', 'PimageClass', array('file' => 'pchart/class' . DS . 'pImage.class.php'));
App::import('Vendor', 'PbubbleClass', array('file' => 'pchart/class' . DS . 'pBubble.class.php'));
$this->autoRender = false;
/* Create and populate the pData object */
$MyData = new pData();
$MyData->addPoints(array(34,55,15,62,38,42),"Probe1");
$MyData->addPoints(array(5,30,20,9,15,10),"Probe1Weight");
$MyData->addPoints(array(5,10,-5,-1,0,-10),"Probe2");
$MyData->addPoints(array(6,10,14,10,14,6),"Probe2Weight");
$MyData->setSerieDescription("Probe1","This year");
$MyData->setSerieDescription("Probe2","Last year");
$MyData->setAxisName(0,"Current stock");
$MyData->addPoints(array("Apple","Banana","Orange","Lemon","Peach","Strawberry"),"Product");
$MyData->setAbscissa("Product");
$MyData->setAbscissaName("Selected Products");
/* Create the pChart object */
$myPicture = new pImage(700,230,$MyData);
/* Turn of AAliasing */
$myPicture->Antialias = FALSE;
/* Draw the border */
$myPicture->drawRectangle(0,0,699,229,array("R"=>0,"G"=>0,"B"=>0));
$font_name = $fontFolder = APP.'Vendor'.DS.'pchart'.DS.'fonts';
$myPicture->setFontProperties(array("FontName"=>$font_name.DS.'pf_arma_five.ttf',"FontSize"=>6));
/* Define the chart area */
$myPicture->setGraphArea(60,30,650,190);
/* Draw the scale */
$scaleSettings = array("GridR"=>200,"GridG"=>200,"GridB"=>200,"DrawSubTicks"=>TRUE,"CycleBackground"=>TRUE);
$myPicture->drawScale($scaleSettings);
/* Create the Bubble chart object and scale up */
$myPicture->Antialias = TRUE;
$myBubbleChart = new pBubble($myPicture,$MyData);
/* Scale up for the bubble chart */
$bubbleDataSeries = array("Probe1","Probe2");
$bubbleWeightSeries = array("Probe1Weight","Probe2Weight");
$myBubbleChart->bubbleScale($bubbleDataSeries,$bubbleWeightSeries);
/* Draw the bubble chart */
$myBubbleChart->drawBubbleChart($bubbleDataSeries,$bubbleWeightSeries,array("BorderWidth"=>4,"BorderAlpha"=>50,"Surrounding"=>20));
/* Write the chart legend */
$myPicture->drawLegend(570,13,array("Style"=>LEGEND_NOBORDER,"Mode"=>LEGEND_HORIZONTAL));
$myPicture->autoOutput(APP.'Vendor'.DS.'pchart'.DS.'pictures'.DS.'example.jpeg');
