There are a few ways to go about this:
1) Use little image blocks to dynamically build bar graphs. It's not too
hard with PHP. Make some little square (or round or whatever) gifs (with
transparent edges), and then position them on a background JPEG or gif using
DIV tags. Make an object in PHP and feed your query results into it?
2) Use the gd library and graphics commands added in PHP 4 (you're gonna
want to read up on this one...) to create images dynamically. This is much
more server-intensive than option #1. and takes more programming, but can be
really slick. Then you can draw all sorts of graphs - not just bar graphs or
3) Combining Java and PHP and MySQL to draw images is also totally possible.
I avoided this approach because it's all client-side. There is also an
example of this in the JDK from Sun, and it works pretty well, but is a
little buggy. Maybe it was my code, maybe it's Java, but it seemed
incomplatible across platforms. Make an object in PHP that creates the
4) Program some really slick ascii graphs. No joke, I did this a while ago.
Nice output. Really fast. You can do line graphs, too.
