Ja klopt, alleen ik krijg ze niet uitgelezen.

Update 24-09-2013:
Door redenen heb ik dit "project" redelijk lang laten liggen.. Heb er zelfs nooit meer aan verder gewerkt. Ik heb de class in de spoiler onder deze tekst geplaatst indien er nog iemand geïnteresseerd is om hem verder uit te breiden. De class zelf is goed gevuld met commentaar.. en de uitlijning is zeker niet slecht..

Deze class werkt met child classes en interfaces om charts te doen. Reden? Niet elke grafiek wordt gelijk behandeld. Daarvoor moet er voor iedere grafiek een child-class worden aangemaakt van de Chart-class.

Success ermee wink
Einde update;

Ooh en even vergeten.. setTransparency($lvl = 0) is voor de doorzichtigheid van een bepaalde kleur..

Wat ik me laatst herinner is dat google met RGB-kleuren werkt.. (255, 255, 255) enzodoor...
Maar ze werken met Hexadecimale getallen.. dus is 255 bv FF

Wat je moet doen is:
$lvl = ($lvl/100)*255;
$lvl = $this->_numberToHex($lvl);
0
