bar chart, pie chart

hello,

i've succeed get the percentage for my application.
How could I convert the result (percentage) into bar chart or pie chart..
tq very much..

its probally easiest to do it as a bar chart, but if you want it as a image, you would have to use either GD or some other extension, or a java applet. But this would mean heaps of work!

You could take a single bar gif and average your data to a percentage by dividing by the total and multiplying by 100 then use that bargif to convert the percentage into a width for the bar gif
$avg = $score / $total;
$avg = $avg * 100;
$width = $avg / 2; //Calculate width. 50 pixels = 100% so I divide score by two.
Such as <img src="images/blahblah.gif" width="<?php print $width; ?>" />
