I must say as a graphic designer I'm really intrigued by this coding to generate graphics. I played around with the script you originally wrote up investigating that very thing (the background). I was able to come accross a line that eliminated the background all together... imagecolortransparent($im, $black); which gave me the opportunity to use css to place a background image behind it. For some reason thought I could not place anything over the chart even using z-index or with the background transparent. Just gonna play around with it some more, well thanks again for all your help.

Cool thanks. I'll take a look at it with the attached image. Thanks for the speedy response!

Hey guys I'm also interested in this topic as well and was wondering if there is a value to show all the gray bars in a 'null' state. I see the -50 value shows one green bar, but what if you wanted to show no green just the gray bars themself, is there a special value for that?
