I used the weight tracking graphs from this site a few years ago:

In the early stages of a diet it's hard to know if it is working - you get on the scales one day and you are 3 pounds heavier than the day before - this averages it so you can see the trends, shows if you are heading for your goals, etc.
Give it a go, it probably helps keep focused on losing weight as well.
