Good luck with the book. Just in case you’re interested, I have a graphing web service called Bellygraph (www.bellygraph.com), that I wrote to track a variety of things (weight loss, miles run, etc). I also included my progress on my last novel. It essentially creates an image that you can host on your website as a burnup chart (or burndown), but you don’t have to maintain the image – just enter new data and the graph automatically updates).

It’s a free service – I just set it up so I could practice with RubyOnRails and have some fun. Check it out, if you like.
