How much work would it take to be able to record the cost of each energy type along with readings (defaulting to the last figure entered) and having the cost graphs calculated based on usage_since_last_reading*cost for each reading, rather than a single value which affects past and present data?
With the rapidly rising energy costs, even if this year's usage graph is much the same as last, the costs will likely be much higher, which might be a useful metric to see?
