The marker is today's value; the faint tick is the one-year median. Every point in this range is the number as it was published on its own date, never a restated figure, so the percentile is what a reader on that day could actually have computed. Ratios at or below zero are excluded rather than treated as cheap. Tickers with fewer than 60 observed dates get no range at all.
