WTH can't the bar chart in the statistics card plot differences between subsequent periods, as in the Energy dashboard

The bar chart in then statistics card plots the sum column from Long-Term Statistics. This is an always increasing set of bars that if anything is much better represented by a line.

It seems to me that there should be an option in the card to plot bars which are “change/consumption during period”, i.e. differences between the state at the beginning and end of the bar’s time period. This is what the energy dashboard shows, for example.

Seems the same as WTH why can't I use the graphs as used for energy/solar/gas for other data - #5 by tom_l to me

I’ve even voted for that one. We can close this and I’ll add a comment there.
