Being a bit anal about such things, I sought out a spreadsheet so as to keep tabs on my electricity and gas consumption, plus spending many months ago. I then adapted it to provide weekly readings. I stopped bothering with it when I moved to a Smart Meter, where our provider put up various graphs on their website.
After moving to a new provider in November, where the SM once again became dumb, I resurrected the idea of manually logging the data with the intention of resurrecting the spreadsheet, which I have just done.
Now I would like to improve the spreadsheet, so as to provide some neat weekly consumption graphs. I know it can be done, but how please?
