While I know the issue of the current history.db size isn't resolved yet 
, I'd like to add a feature request in the mix.
Currently, while the montly cost summary contains 12 months worth of historical information - which I know is the problem with the db size... I'd actually like to see my usuage 13 months ago or for a period of even more (user selectable). That is, I'd like to know the amount of electricity I used last November (given we are in November now).
Again, given where we are with respect to time (now) and as the information from Sept or older aren't graphed, I don't understand why this information can't be calculated and inserted in a separate table in a single row for each month. Even given no maintenance to this historical data from a database prospective, the would amount to no space used and could be laid out as:
Monthly_History_table
Month YYYY Usage Cost
------ ----- ------- -----
Aug 2011 900 kwh $100
Sep 2011 800 kwh $ 85
As October is currently used in the graphing of last months vs current month,
keep it there until the current month becomes current month +1, then add the calculated summary to the aforementioned table, then purge all the data from whatever table is used to graph.
Again, I'd like to know what I used this time last year and think this would also solve the database size issue...
