On the "ma-set-point-value" it is possible to change the step of incrementation but is there a possibility to do the same thing on "ma-point-value" when one displays enable popup
Change Step in ma-point-value
Currently its not possible. I just made it possible in 3.6 though, it should be released in the next couple of weeks.
Ideally these sort of settings should be stored with the data point.
