Charting Weight Change With Google Visualizations

July 5, 2010

I started trying to lose weight a while back, since we both know I’m a bit heavy and sitting in front of a computer isn’t going to lose the weight for me.

Naturally, it’s important that I incorporate technology into my weight loss somehow, right? So I decided to give the Google Visualizations API a spin.

I worked up a quick data format and a method to pop the data out. Nothing fancy, just a fixed width flat file. This doesn’t deserve a database.

Easy to read, easy to edit, and easy to consume. Every morning I just hop on the server, add the day’s weight and log off.

Now I just needed to represent it. The API is very object oriented and easy to work with. I wish there was a less verbose way of presenting the data, but you can’t have everything.

Actually, there may be a better way, I just didn’t come across it while speed reading the docs.

And there you have it, fancy charting in no time.
