Thanks for your amazing tutorial. It's really helped me to get to grasps with creating a dynamic graph image. What I would like to know though, is how do I change the size of the border? I would like to make the border thicker, and is it possible to use HEX colours?

I would personal have ended the code with a:
imagedestroy($per);
Make things faster :D

@Manny: i've resize the image not from the code, but from the <img> tag and works fine :)

Eg:
<img src="graph.php?per=68.5" height="15" alt="76.82% graph" />

Thank you. Code is small and easy to integrate with web cms

hey, I was wondering what needs to be edited in order to resize the graph? I resized the gradient file to 100 pixels wide, and also imagecreate(102,7); and imagerectangle($per, 0, 0, 101, 6, $border);

but my graph, although works without errors, is not displaying the correct percentage in terms of graphics, any help?

Matt,

If you save the image to your computer and open it up in a text editor you will most likely see an error message that will help you diagnose the problem.

If you don't see an error when you open the image in a text editor then you probably have display_errors set to 'Off' in your php.ini. If that's the case then set display_errors to 'On' and save the image again so you can see the error message.

I can not get the graph to work. I copied it exactly from the site

and when I try it I get...

The image �http://acri/it/tasks_list/graph.php?per=67.89� cannot be displayed, because it contains errors.

Why could this be? I have GD running and all.

Yeah could'nt get it to work at all without the semi-colon.

You shouldn't need a semi-colon after the 'per' parameter in the URL. Were you not able to get it to work without the semi-colon?

Your missing the ; after the varible in the image link it should be:

<img src="/media/examples/graph.php?per=76.82;" alt="76.82% graph" />
