	// PHP GRAPH GENERATION SCRIPT
	// By mr_flea (mrflea at gmail dot com)
	// don't forget to remove the .txt part of the extention before trying to use it.
	// Usage:
	// $graph[bar number][(rowdata|r|g|b) - insert a bar. start at number 1. rowdata is a value between 0 and 100. r = red, g = green, b = blue, ALL 4 VALUES MUST BE SET FOR EACH BAR.
	// $graph['title1'] - title first line
	// $graph['title2'] - title 2nd line
	// $graph['y1'] - y axis title, first line
	// $graph['y2'] - y axis title, 2nd line
	// $graph['x'] - x axis title
	// $graph['numbars'] - number of bars
	// end of notes
	// sorry about the lack of features and having to give it stuff like number of bars, the next version will be better if I ever finish it.
