A percentage has a real ceiling the way zero is a real floor, but the gap that
keeps series off the plot edges did not know that: a battery reading 20-100%
rounded out to an axis labelled up to 120%, and one sitting flat at 100% — a
device left on the charger — reached 160%.

Recognise the unit at the two line-chart call sites and hold the axis at 100,
mirroring the existing zero clamp. Only while the data stays under it, since
power factor is also reported in % and is signed.
