ChartLet will periodically check the places you want on the Web, extract and store numerical values.On demand, you can display the history of those values in nice charts.

Not only you can capture a value directly displayed on a page, like a temperature or a stock quote, but you can also extract the rank of an item in a list, or the number of occurrences of an expression in one or several pages.

Of course, you have a total control of what is retrieved by your browser and how often extractions happen.

Each extraction configuration is controlled by a chartlet. You can install and run as many chartlets as you want.

Requirements:

· Firefox: 1.5 – 2.0.0
