linux/php graph or chart tool

Anon

I have just inherited a functioning www site and been asked to make some changes to existing php/jscript/linux/apache based world. I come from primarily a sysadmin background and have development experience on several platforms-none of it web related of course. I need information on what open source tools might be performing these php related graph functions on this machine. for example a user selected a range of informatoin between dates and it is then graphed and displayed etc. These graphs are substandard in appearance and just look generally unprofessional. Any idea what tool this is, where I look to find out and what tool I can use to improve this appearance?

I'm currently using PDFlib to generate
pie charts in PDF format for reporting
purposes, and I think it would be pretty
simple to do bar charts as well, though
I haven't done this yet. It might even be
possible to do XY charts.

It's probably a bit more code intensive,
but you may have more flexibility.
I've never used phplot so I don't know
anything about it.
