I end up setting the axis properties too.
If you revert axis settings (right click on y axis) then it should go back to auto scaling.
I feel like an add-in that sets axis min and max based on some range* of the spec limits might be useful - anyone have that handy?
*something like axis max/min = LSL +/- 10% of spec range.
