Engine vitals chart — coolant, oil, and intake-air temps on the
same axis. Three series resolve their key + unit through the PID
catalog so every line swaps to °C when the units preference is
metric.
Drops any series whose PID wasn't logged via Recharts'
undefined-value handling. If none of the three were logged, the
chart falls through to its empty placeholder.
