there is a typo in the word High.

You spelled it Hight when it should be High

class.cchart.php:512: elseif($trigger['priority'] == 4) $color = 'Priority Hight';
class.cgraphdraw.php:99: 'Priority Hight' => array(255,100,100),
class.cpie.php:124: protected function calc3dhight($height){
class.cpie.php:529: $this->calc3dhight($this->sizeY);
