Currently, if you change the vertical scale in a profile view, it always reverts back to a vertical scale of 10 if you switch the view to display the profile of a different Line. It would be much better if the scale in the view would stay at whatever you set it as rather than reverting back to 10 every time. It would also be much better if the default vertical scale was 1. We find It is very difficult to work in the profile view with a vertical scale of 10 therefore we have to switch it to 1 or 2 every time a profile view is opened.
