Yeah, I would say the y-axis range on charts should be set at "3-sigma likelihood of observation" thresholds. Not everything that's charted can be framed as sampling from a distribution, but the principle of manually setting chart ranges would nonetheless still apply.
For instance, if we're charting someone's body temperature, we would likely fix our y-axis to 80-110.
