How to create a jpeg bar chart with php

Please let me know the easiest method to create a JPEG/GIF bar chart
from PHP.
I have found solutions that allow creation of swf/flash charts but I
need a jpeg/jpg/gif bar chart.

I need to know how to create stacked bar charts.

GlobFX's Swiff Chart Generator is quite expensive but produces pretty much
anything you might want, including jpg:

Another popular graphing library for PHP is JpGraph, found at
http://www.aditus.nu/jpgraph/. It might be perfect for you so I suggest you
try it out.

As you'd have access to the height of an image even through HTMLs IMG
property, you could make each bar one colour JPEG/GIF image block and
access that using data from a database to change the height of the block.

I'd imagine the actual value would have to be the top-most location
value minus the height if you want the bottom to stay along a horizontal
line, the values growing upward.

I read that in the post I replied to but sometimes it's good to 'get
down and dirty' and learn what is going on unless the poster 'can't be
arsed!' ;-)
