…otting (Codex P2 #1, #2)

The palette assigns colors by group, so regrouping into current and previous painted both bars of a slot alike for a caller that sets no stroke. A previous period with no counterpart had no front bar to stand behind and was drawn in the wrong slot.

With the keyboard tooltip open, hiding a series from the legend left
the selection in place, because the point count did not change. The
tooltip effect then re-showed the remaining series on top of the old
tooltip data, so the hidden series stayed listed.

Pass the visible labels as visibleSeriesKey, as BarChart does, so the
navigation hook clears the selection when the visible set changes.

* Charts: Keep hidden series out of the line chart keyboard tooltip

LineChart handed the keyboard tooltip every series, hidden ones
included. In group mode the tooltip shows a datum for each series it
gets, so arrowing through a chart with a legend-hidden line still
listed that line, while the pointer tooltip (which only sees rendered
lines) did not. The last series shown also became nearestDatum, which
consumers read for the tooltip heading.

Pass only the visible series. The two existing visible-series
filters now share the same memoized list.

* Changelog: Add entries for the line chart keyboard tooltip fix

Premium Analytics renders line charts that can hide series, through
its interactive comparison legend and defaultHiddenSeries, so its
users can see the fix. The Jetpack plugin ships the same dashboard
behind jetpack_premium_analytics_enabled. Publicize, VideoPress and
Newsletter line charts cannot hide a series, so they get no entry.

* Address review: Name keyboard points from the first visible series

With the first series hidden, the tooltip now showed the next visible
series, but Enter and Space still handed the hidden series' datum to
onDatumActivate, and the keyboard stopped at the hidden series' last
point. So the activated point disagreed with the tooltip, and a
longer visible series could not be reached.

Read both from the first visible series instead. (Codex P2 #1)

* Address review: Close the keyboard tooltip when visible series change

With the keyboard tooltip open, hiding a series from the legend left
the selection in place, because the point count did not change. The
tooltip effect then re-showed the remaining series on top of the old
tooltip data, so the hidden series stayed listed.

Pass the visible labels as visibleSeriesKey, as BarChart does, so the
navigation hook clears the selection when the visible set changes.

* Address review: Reach every visible point by keyboard

Counting stops from the first visible series broke navigation when
that series was empty or shorter than a later one: hiding the first
of [A, empty B, C] left no stops at all, although C is drawn. Before
this branch the hidden first series set the count, so that chart was
still navigable.

Count stops from the longest visible series, and name an activated
point from the first visible series that has one at that index.

* Address review: Rebuild the grouped keyboard tooltip from scratch

visx merges every shown datum into the previous tooltip data. When a
series was hidden while the keyboard tooltip stayed open (focus in the
chart and a changed point count, so the navigation hook clamped rather
than cleared), the group re-show added the visible series but never
dropped the hidden one, and its row stayed in the tooltip.

Clear the tooltip before showing the group, so it holds only the
series it is given. (Claude final review)

* Address review: Describe index re-pointing for line charts too

The navigation hook comment said hiding a series moves every index
onto a different bar. LineChart now passes visibleSeriesKey as well,
where an index is an x position, so the bar wording no longer fits.
(Claude final review nit)

* Address review: Check the clamped tooltip stays open

The assertion only checked that Series A left the tooltip, which also holds if the tooltip closes. Checking that Series B is still listed keeps the test on the clamp path it exists for.
