How to have power flow show negative values, right now it only can show positive

[Darkyputz]

Describe the enhancement

I have a small PV setup that feeds my house but not the grid. I am watching all of it with esphomed emporia ct's and everything is working great. Besides that production is value wise shown as negative (which i want) but when clicking on the value to get the detailed view on how it did over the day i only get a flat line (see picture)
Clicking than on History on this same screen i get the date picker and so on and it shows above and below 0 development of the power.
How can i have the first detail screen show the over the day development right away as it is showing in the long term history.
Or can this be changed for the next release as a feature/repair

Use cases

It seems to be a missed item, since it works throughout the whole software besides this one particular screen.
It would save an extra drilling into the next screen and date pick.
And while it is already a day summary screen it should just work
