TL;DR
Add a button in the Production Window that copies filters from the Production/Consumption graphs to each other.What ?
I suggest adding an extra "Copy filter" button to the production and consumption graphs, next to the "reset filter" buttons (shown in red in the first screenshot).This "Copy filter" button will copy the filters used for the other graph. Meaning if you press the Consumption "Copy filter" button in the first screenshot, the filters from the production graph will be copied onto the consumption graph. (Like shown in the second screenshot) Bonus thoughts: The button could also be "grayed out" when the graphs have the same filters or if the other graph is unfiltered, showing that there is no filter to copy.
Bonus Bonus thought: Please make the colors of the items graphs match if the two graphs have the same filters.
