Bars above the line are months when money came in; bars below it are months when investors took money out.
On the net assets line. Net assets are reported quarterly, so the same figure repeats across the three months of a quarter. It is drawn as a step rather than a curve so that repetition reads as what it is — one reading held for three months — and not as a flat trend.
