The current scale option is that whenever starting to run a scenario in controller.
All graphs always start with scale size 1.
So, need to change a scale size then save of the scale of online graphs from 1 (default) to 10 (customer - whichever the scale to be) in controller.
But now even If team want to change to a different scale, team has to manually set it up at the beginning of every test which means that the changed scale is not saved at all.
so that the team has do this extra step every time.
