In my opinion it is very confusing that different diagrams take different filter fields into account. I understand that the fixed "axes" of the diagrams can't be their parameters, but this is exactly what makes them unnecessary.

If we want to keep filter pane on the left, then we should at least visually indicate which fields serve as parameters to the specific diagrams in the future. For example hovering a diagram could fade out and make transparent unused filter fields.

@bruntib Yes, you are right, but now at least the users will see how these numbers are calculated. You can create a separate issue for this problem and we will discuss this problem how we can solve it nicely there.
