What is the "comparitive" graph for a power widget ?

[Thorgal789]

Hello, I have a power widget, used only for power, it mesure 700W during 3 hours by days.
It working fine, no problem with him, but if I go to logs, the last one if the "comparative" by years, but what is the value compared, it's something like 7 000, 00 W

It's the power * hour * days ? but the value is not the good one.

I realy have no clue where this value is from ....

Like other sensor data like lux, or data of a custom sensor think this is an average value.
