   AFAIK we don't support auto scale for other graphs. That sounds like an improvement, but I'm not a FE engineer and we even don't seem to rely on graph library (which may provide rich functionalities) and implement our own, hence harder to make an improvement.
   
   The value can goes up very high if you set the additional delay of watermark to a couple of hours or even more (2 hours = 172,800 seconds). While scaling unit would make us confused, adjusting min/max of y axis might be helpful. I'm just hesitate to make change as I see all existing graphs have 0 as min value of y axis, though.
