Energy: fixing solar production y-axis scale to maximum/fixed

It would be nice if within the energy dashboard the solar production would (or could) be shown with an fixed y-axis scale. Preferably to the theoratical maximum of the solar installation or any given amount. Now it’s less easy to compare days and I’m interessed how my panels performed during the day. Also the estimated values show better what kind of day it will be.
I think this will be most useful for day, week, month views
