A stacked bar cannot be read on a phone. There is nothing to hover, so the
bar's title is unreachable, and the only way to get a day's figure was to
estimate it against the axis — which a split bar makes harder, not easier.
Tapping a bar now writes that day out beneath the chart: "Sun, Sep 20 — Dry
260 g · Fresh 100 g · 360 g in total", or just the total where no kinds are in
play. The same problem exists without kinds, so it is not gated on them; the
unsplit form says the number once rather than "No kind 340 g · 340 g in total".
It reads off the day already selected rather than keeping a selection of its
own. Tapping a bar selects that day on every chart in the app and this one
already highlights it, so a second piece of "which day" state would only be
something to keep in step and eventually fail to. It falls out of that choice
that the arrows and the date picker move the readout too, which is the
behaviour you would want anyway.
Three cases say something rather than reading as blank: a day with no food, a
day marked not counted, and a day outside the window — which has no bar, so no
readout.
The changelog entry for this sits on its own rather than inside the food-kinds
one. It started life gated on kinds and is not any more, and "once you are
using kinds" would have been the wrong condition to file it under.
