Option to show legend – especially unit – on the axes (similar as before)

Is your feature request related to a problem? Please describe. As an end-user who is used to work with data, I expect data graph to always have a clear legend – especially a UNIT! – right next to the axes (especially on y-axis) in order to make clear what the numbers actually mean. Currently there is no unit visible at all (even in the pills on top)

Describe the solution you'd like

Minimum: At least the units should be visible
better: enabling users to show a – configurable – legend right on the y-axis similar to the way it was before (see screenshot below)
ideally: also improve readability of the label (compared to the old DP graph) – could mean bigger size font/more contrast or maybe just using UPPERCASE?!.

Describe alternatives you've considered While some of the information is still there (as pills on top of the graph) and definitely easier to read as before, the unit is currently missing – and the connection to the graph is not that easy to understand anymore – especially for new and occasional users.
