Shameless plug.

I've started a project to track any data that I want and stop relying on all of these free sites because of this loss of data issue.

The source code is here: https://github.com/mcormier/tallyman

and you can see it in action here: http://stats.preenandprune.com

I haven't tackled generated graphs from the SQL data yet but plan to eventually. The one graph on the page was generated with Apple's Numbers. Since it's annual data I don't plan on updating it more than once a year.
