Invisible to everyone

Kemarin habis bikin Class buat nge-generate Grafik dalam bentuk gambar dengan PHP, Grafik ini hanya melapporkan dua item (Rata-Rata dan Total), item ini bisa diubah sesuai kebutuhan, cuma ganti caption-nya doang ,

        }
     
   
   
    } 

?>

cara pake nya bisa seperti ini

<?

$sampelData = array(
      ‘1′ => array(
        ‘nama’  => ‘TO Pertama’,
        ‘total’ => 60,
        ‘rata’ => 56
      ),
      ‘2′ => array(
        ‘nama’  => ‘TO Kedua’,
        ‘total’ => 50,
        ‘rata’ => 40
      ),
      ‘3′ => array(
        ‘nama’  => ‘TO Ketiga’,
        ‘total’ => 43,
        ‘rata’ => 60
      ),
      ‘4′ => array(
        ‘nama’  => ‘TO Keempat’,
        ‘total’ => 12,
        ‘rata’ => 40,
      ),
      ‘5′ => array(
        ‘nama’  => ‘TO Kelima’,
        ‘total’ => 59,
        ‘rata’ => 40
      ),
      ‘6′ => array(
        ‘nama’  => ‘TO Keenam’,
        ‘total’ => 7,
        ‘rata’ => 10
      )
      ,
      ‘7′ => array(
        ‘total’ => 13,
        ‘rata’ => 34
      ),
      ‘8′ => array(
        ‘total’ => 4,
        ‘rata’ => 21
      ) ,
      ‘9′ => array(
        ‘total’ => 0,
        ‘rata’ => 40
      ),
      ‘10′ => array(
        ‘total’ => 30,
        ‘rata’ => 40
      )                                                           
    );
   
   
    $graph = new Grafik_Kacung;
    $graph -> setFont(’bookos.ttf’);
    $graph -> setData($sampelData);
    $graph -> setCanvas(350,550);

?>

 Kurang lebih hasilnya seperti ini:
