Request to Set Default Y-Axis for Charts Above Zero

I would LOVE to be able to set a default for generations to not include zero in the axis for charts - the current default starts charts at zero, and of course we can change that in editing, but it would be very helpful to just make it the default by choice. my use case will send automated monthly updates to homeowners so we are measuring small changes in price - the charts look much more dynamic with smaller increments in the y axis than starting at zero
