On the dashed segments. Forbes revalues privately held fortunes only occasionally — Koch Industries or Mars, for instance, can sit unchanged for months while a public-equity fortune moves every session. Where the source reports no change for more than three consecutive trading days, the line here is drawn straight between the two real readings rather than stepped, and rendered dashed. Those stretches are an assumption about the shape of the move, not a record of it. Solid means measured.

On the faint dotted stretches. Forbes lists nobody worth under $1 billion, so a fortune that dips below drops off the list entirely and no figure is published until it returns. Three quarters of the people here are absent at some point — usually days, occasionally years. Those spans are bridged faintly so the person stays visible at their low points rather than silently vanishing; the dotting means nothing was published, not that the fortune held steady. Select a single person to see each absence shaded with its length.
