//建立畫布

//設置圖像邊界範圍
$graph->img->SetMargin(30,30,80,30);


//設置標題
$graph->title->Set("餅圖");


$graph->title->SetFont(FF_CHINESE); //--設置支持中文標題


//獲得餅圖對象
$piePlot = new PiePlot($data);


//設置圖例
$piePlot->SetLegends(array(1,2,3,4,5,6,7,8,9,10,11,12));

//設置圖例位置
$graph->legend->Pos(0.01,0.45,"left","top");


//添加到畫布中
$graph->Add($piePlot);


//輸出
$graph->Stroke();
