I use MySQL also.  Pretty easy to setup. 

I also use the full XAMPP software, and that allows me to produce graphs using the jpgraph on the local pc. (not that you couldn't set this up on your own, but it's a no brainer to setup a server using xampp/lampp)

Here's an example of the results:


The images and table data are uploaded automatically every 10 minutes.

It's very easy to figure out. Lots of examples out there. If you're trying

to make some nicer looking graphs than what rrd does. I haven't had time to
get too far into it, so I have no idea what it takes to get it working.
