…ctive dots Recharts' axis tooltip and Plotly's hovermode="x unified": with mode="x" the pointer only has to be inside the plot, its horizontal position snaps to the nearest x value, and every series' point at that x is listed at once while the vertical position is ignored. The plot divides into full-height bands whose boundaries fall halfway between adjacent points; a cursor line marks the snapped x; each series shows an active dot; the tooltip follows the pointer. mode="y" mirrors it along the y axis. The default, mode="nearest", is unchanged and ships nothing new on the wire. Client: `_hover` routes to `_hoverBand` when the mode is set. `_bandHits` snaps every eligible series (point and line marks with retained CPU columns; density tiers, bars, rectangles, ribbons, funnels, heatmaps and segments keep their own hover geometry, legend-hidden series are out, polar falls back to nearest) to its nearest point along the band axis via the new `_nearestCpuIndexAlong` (which `_nearestCpuIndex` now delegates to), takes the candidate closest to the pointer as the band, and admits every series whose snapped point projects to the same coordinate within 0.5 CSS px. The band tooltip renders a title for the coordinate (or the authored template) and one row per series with the name painted in the series colour, honoring fields/format; it follows the pointer rather than anchoring, and a new `tooltip_cursor` DOM slot draws the line across the plot, reprojected on every draw. Active dots draw from the CPU columns through a scratch VAO rather than each trace's vertex buffer (a smoothed or stepped line's vertex index is not its data index), in the series colour. `xy:hover` carries one `points[]` entry per series; one exact pick per series goes to the kernel and each reply replaces its own row, matched by seq ahead of the single-pick sequence check. Fixed on the way: the existing nearest-mode hover highlight dot had stopped rendering. The full point program multiplies fill alpha by the per-item `a_style.x` factor; the regular scatter draw moved to the simpler point program that never sets that constant attribute, so `_drawHoverPoint` inherited its default of 0. It now sets every constant attribute and stroke uniform the program reads, and a probe pins the highlight paint landing on the presented canvas. Spec: interaction.md §7.3 (new) and the §3 xy:hover row; the slot joins styling.md, chrome-slots.md and the regenerated capability matrix (48 -> 49 slots; counts updated in export.md and the dossier); a live capture under spec/assets. Docs gain a "Shared Tooltip Along an Axis" section with a demo. Tests: wire option (opt-in only, validation, dataclass positional order, re-validation of a mutated node), browser probes for the x band (far-above selection, same-band re-placement without new picks, midpoint boundary in both directions, outside-plot hide, legend-hidden exclusion, cursor geometry, series-coloured labels and active dots measured on the presented canvas, one pick per series, xy:hover points), the y band, the unchanged default, the restored nearest-mode highlight, and byte-identical static exports.

…er under show=False Edge-case pass over xy.tooltip(mode="x"|"y"). Four breaks, all fixed with browser regression tests: - Bars were excluded from bands, so a bar chart in band mode showed no tooltip at all. A bar's footprint (pos +/- width/2 in plot px) is now its band extent; touching footprints chain into one band, so grouped slots read as one category with the cursor and title on the category centre. Bar series snap to the chain, not the pointer: from the gap after a category the pointer is nearer the previous category's slot of the far series, which listed one series instead of all. - The band-dot scratch VAO outlived its GL context. After a context loss the recovery frame bound the dead handle, the frame-ready check saw the error, and the restore retried forever. _initGl forgets the scratch objects before rebuilding; destroy() deletes them (they leaked into the shared host). - show=False dropped xy:hover in band mode; nearest mode keeps it. Only the tooltip element and cursor are hidden now. - Bar-band titles showed the category index instead of its label. Probed and unchanged: interleaved x grids, log-axis boundaries, time titles, NaN rows, y2 series, all-hidden legend, zoom off-plot, density + line mix, decimated 1M-point line, 30 series, duplicate x, single point, keyboard after band, polar fallback.

… chains Six review findings on this PR, five of them reachable from supported charts: - A category-filtered trace draws a subset, so `_visMap` maps each drawn instance to its shipped row while `g.n` counts the drawn ones. Treating `g.n` as a prefix of the CPU column made the band scan rows the legend had hidden and drop visible rows past the prefix. Walk the map's source indices instead. - A band pick reply the kernel could not resolve, or one whose trace has since gone, returned silently and left the band's rows and cursor on screen describing points that are not there. Exact or nothing (§16), as in nearest mode: hide. - A reply could also replace a row it was never requested for, because `seq` alone does not prove the slot still holds that series — the map is rebuilt per band. Verify the trace and index against `_hoverTargets[slot]`. - Every band active dot read row 0's size, since the scratch buffer holds one vertex and its index was used for the size-channel lookup too. Pass the hovered row for that lookup and keep drawing vertex 0. - The dots uploaded raw CPU columns while the cursor and title used transition-interpolated coordinates, so mid-transition the dot sat at the final position. Interpolate in encoded space, which is what the buffer takes and avoids a decode/re-encode round trip. - The grouped-bar chain expansion ran only when the ANCHOR was a bar, so a line or area point anchoring a category that also holds bars listed the line and dropped every bar beside it. Run it whenever any candidate is a bar; the passes already ignore non-bar candidates. Docs: `mode="y"` is a y-axis mode on any Cartesian chart, not a horizontal-layout-only one, and the `tooltip_cursor` slot serves both modes.
Brings the branch up to 72a069f; the five commits since are docs-site only and merge without conflict.
Each fails on the unfixed client and passes with it: - a category-filtered trace whose drawn rows sit past a -sized prefix resolves to a drawn row, never a hidden one (the prefix scan returned row 1 of 5 instead of row 4, and returned a hidden row outright when the pointer sat on one); - a band pick reply for a row its slot no longer holds is ignored rather than overwriting that series (the unfixed client showed `pv12345`), and a reply the kernel could not resolve takes the band down instead of leaving a stale readout titled from the wrong category; - a line point anchoring a category of four grouped bar slots keeps every bar in the band. Four slots are what makes it visible: the inner two touch at the centre so the line beats them on distance and anchors, while the outer two do not reach it — the unfixed client listed `uv`, `amt` and the line, dropping `pv` and `qty`.

… hidden greptile's first full pass over this PR found three lifecycle defects; none were in the eleven threads fixed earlier. - Shared-axis snapping accepted any finite projection, so a row panned or zoomed off the plot stayed selectable. A pointer inside the plot could therefore raise a tooltip and hover state for an invisible point, with no cursor to locate it (the cursor already refuses to draw off-plot). A candidate whose footprint lies wholly outside the band axis is rejected; a bar counts as visible while any part of it overlaps. - The band holds GPU trace objects and rows resolved from them, and both `updatePayload` and a non-in-place append replace those objects. The band survived, so the next draw painted active dots and tooltip rows from the retired traces against the new axes until the pointer moved. Both replacement sites now drop it; an in-place append keeps the object and needs no reset. - With `show=False`, `_renderBandTooltip` hid by clearing the whole band. That is wrong on its own terms -- the mode's contract keeps the hover event, the picks and the active dots, and `_hoverBand` already treats it that way -- and it dropped `_bandPicks` while their replies were in flight. Those replies then missed the band map, and the last still matched `_pickSeq`, so it fell into the single-pick handler and dispatched an `exact: true` hover carrying one series where the band promises all of them. Hiding now touches only the element, and abandoning outstanding picks advances `_pickSeq` so a late reply can never be read as an ordinary point. Three browser regression tests, each failing on the unfixed client: a view panned clear of the data selects nothing and shows no cursor (and recovers when panned back); a real `updatePayload` leaves no band behind for the next draw; and a hidden shared tooltip keeps its two targets and pick bookkeeping across replies, dispatching only whole-band exact hovers.

…n a dead context Four review findings across greptile, cubic and CodeRabbit, each with a regression test that fails without its fix. - A bar joins the band while ANY part of its footprint overlaps the plot, but `_positionTooltipCursor` hides on an off-plot coordinate, so a bar more than half clipped by the edge was selectable with its band centre outside: the tooltip appeared with nothing locating it. The cursor now carries the band's footprint and is drawn on the part that is visible. A point band's footprint is its own coordinate, so nothing moves. - `fields=["x"]` in `mode="x"` asks for the band coordinate and nothing else, which the title already carries — the rows should be names alone. Filtering the band field out and then testing the remainder for emptiness read that as "no fields configured" and fell back to the default y value, ignoring the selection. An authored EMPTY list still means unset, as in nearest mode. - `updatePayload` and `_applyAppend` return early when the GL context is gone, having already replaced the retained spec and payload. Recovery rebuilds every GPU trace from those and touches no hover state, so the band outlived the traces it was resolved from across the whole restore. Both early returns now drop it, as the live paths already did. - The shared-tooltip docs promised an active dot for "each series"; bars get none, as §7.3 says, because the bar is the mark.

cubic (P2, re-detected) and CodeRabbit on `_bandCandidate`. The guard added for the band axis states the rule in its own comment: a coordinate that has left the plot cannot be picked by a pointer inside it, and accepting one produces a tooltip and hover state for an invisible point with nothing marking where it is. Only `lo`/`hi` were bounded, and those run along the band axis alone, so the other axis was never asked. Measured in the real client -- two lines, y axis pinned to 0..5, series B at ~504, hovering mid-plot in `mode="x"`: rows ["A1.4", "B504"] series B pixels in plot 0 series B pixels outside 0 So B reported a value 100x above the visible range while painting nothing anywhere to locate it -- the exact case the band-axis guard exists to prevent, one axis over. The pointer still ignores that axis when choosing the band; §7.3 is about what selects a point, and this is about whether the point is on screen at all. A bar is a span rather than a coordinate there: it runs from its baseline (`value0`, else `value0_const`) to its value, so it stays while any part of that span overlaps, mirroring the footprint rule already used along the band axis. Collapsing it to the value alone would have dropped every bar taller than the view, which is the ordinary zoomed bar chart. Measured: bar body crosses plot, top far above kept rows ["bars50"] bar wholly outside the view dropped rows [] bar fully in view kept unchanged Two tests, both failing on 4a542b6. Full suite 4369 passed; the three failures are the two `test_shared_glhost` pixel hashes that fail the same way on unmodified sources in my sandbox, and `test_bench_vs`'s hard timeout, which passes 3/3 run alone on this commit and on 4a542b6 alike.

@Alek99 — I pushed one commit to this branch ( What was blocking: cubic wasn't withholding approval over a style nit — it was re-detecting an issue it had already reported, which blocks its auto-approval outright. CodeRabbit filed the same thing independently. Both point at Why I treated it as a bug rather than a design question: the guard you already wrote states the rule in its own comment —
That's exactly what still happens on the other axis. Two lines, y axis pinned to B reports a value 100× above the visible range and paints nothing anywhere to locate it. No gutter bleed — the dot is clipped away entirely, so it's your stated failure mode precisely, one axis over. This doesn't touch §7.3. The pointer still ignores the perpendicular coordinate when choosing the band; this is only about whether the chosen point is on screen at all. The bar case is why it isn't a one-liner. A bar is a span on that axis, not a coordinate — baseline (
Two tests added, both failing on One thing I did not decide for you: whether a series that's off-plot vertically should still be reportable by design — someone could argue a time-series band ought to tell you a value even when you've zoomed past it.

…data space Five review threads, four of them against 872c139's own fix. cubic (P2, conf 10) and greptile: a bar is a span on BOTH its axes, and `mode` decides which one is perpendicular. 872c139 only ever measured baseline..value, so whenever the band axis was the VALUE axis -- `mode="y"` on vertical bars, `mode="x"` on horizontal ones -- the bar was treated as a bare coordinate on the position axis it actually straddles, and every visibly clipped bar was dropped. A single bar spanning -0.4..0.4 with the view starting at 0.1 went from selectable on 4a542b6 to gone on 872c139. `_barSpanAcross` now answers per axis: `pos ± width/2` across the position axis, baseline..value along the value axis. greptile (P1): rows that TIE on the band coordinate are equally "at" it, and `_nearestCpuIndexAlong` keeps the first. Once visibility gated the candidate, that arbitrary pick decided whether the series appeared at all -- a point whose twin at the same x is plotted took the series out of the band. A tie now prefers a row that is drawn. Only exact ties: a farther row is at a different coordinate, and §7.3 omits a series with no point there rather than guessing one. greptile (P1): a stacked update animates the baseline. `_cpuPointValue` already interpolates the tip; the baseline was read settled, so a bar drawn across the plot mid-transition vanished from the band while it was on screen. The baseline is interpolated the same way. greptile (P1) and cubic (P2, conf 9), both pre-dating 872c139: the band cursor's footprint was captured in plot PIXELS at hover time, but `_positionTooltipCursor` reprojects `x`/`y` on every draw and a pan or zoom does not rebuild the band. Panning B's bar to span -10.1..78.6 against a plot starting at 62 put the cursor at 73.1 instead of the visible edge at 62. The footprint is carried in data space and projected through the current axes, so it moves with the point. cubic (P3, conf 9): `Object.keys(view._bandPicks)` is always `[]` because `_bandPicks` is a Map, so the hidden-tooltip test asserted nothing. It reads `.size` now -- and passes, so the bookkeeping was right; the test just was not proving it. Four new tests, each failing on 872c139; the off-plot-perpendicular one from 872c139 is kept and renamed. Full suite 4371 passed. Run alone, the only failures are the two `test_shared_glhost` pixel hashes that fail the same way on unmodified sources in my sandbox; `test_bench_vs` and `test_legend_best_live` fail only under full-suite load and pass in isolation here and on 4a542b6.

Four more threads, three of them against 32bd953's own fix. greptile (P1): `_transitionPrevValue0Values` is written as `encode(value0, newBar.value1Meta)` and read back by the animation itself through `oldBar.value1Meta` -- the start baseline rides the TIP's metadata, not the baseline column's. 32bd953 decoded it with `value0Meta`, so wherever the two columns differ the visibility check measured a different bar from the one being drawn. The test did not catch it because the probe encoded its fake transition state with `value0Meta` too: test and code agreed with each other and both disagreed with the real producer. It now encodes the way the animation does, and the fixture gives the two columns deliberately different ranges (offsets 0.5 and 10000) so a wrong decode lands thousands of units away rather than within rounding. Wrong decode: start baseline -9699.5, span -4849..50, bar misses the 100..200 view. Right: 300, span 50..150, crosses it. Fails on 32bd953. greptile's second point on that thread -- that this interpolates data values while the shader interpolates projected positions, so log and symlog axes can disagree -- is real but predates this work: `_cpuPointValue` interpolates the TIP the same way for every band and hover readout. Fixing it belongs in one place for both tiers rather than here, and is left as a follow-up. greptile (P1): a band can hold series bound to different axes, and data values from two axes do not share a number line. One min/max across the band mixed them -- bars at 0.6..1.4 on `x` and 60..140 on `x2` union to 0.6..140, a range neither occupies -- and it was then projected through the anchor's axis alone. Each slot now keeps its own axes and is projected separately, unioned as pixels. Pinned structurally rather than by a moved pixel: the bad union only ever widened the span, and a span wider than the plot clamps to the plot, which is where a bar clipped at the edge wanted the cursor anyway. No input I could build moved it, and the test says so. cubic (P2, conf 9): the `rows()` refactor in 32bd953 dropped the `targets == 0` assertion the off-plot bar case had in 872c139, so an invisible bar could have stayed an active hover target unnoticed. Both away cases assert rows and targets again. cubic (P3, conf 8): `hover(x, y)` is CANVAS-relative -- it sets `clientX = rect.left + x` and `_hover` takes `clientX - rect.left` back out -- so `_band_at_centre` aimed (plot.x, plot.y) up and left of the centre it named. Worth more than its priority: with the pointer actually at the centre, the tie test landed on x=2 instead of the tie at x=1 and failed. It was passing because it was mis-aimed. It now hovers the tie directly. Full suite 4373 passed. Run alone, the only failures are the two `test_shared_glhost` pixel hashes that fail the same way on unmodified sources in my sandbox; `test_legend_best_live` fails only under full-suite load and passes in isolation.

The shared-axis hover path treats these coordinates as plot-relative, but the helper adds the plot margins. When the plot has margins, the tests probe a band away from the centre, so a regression at the actual centre could go undetected.

P3: (view._bandCursor || {}) && state().cursorLeft is an ineffective guard: {} is truthy, so the expression always evaluates to state().cursorLeft whether or not _bandCursor exists. The field is also never read by the Python assertions (they use payload["state"]["cursorLeft"]), so both the payload member and its bogus guard are dead weight. Simplify it or drop it.

Adding the active dots exposed that the existing nearest-mode hover highlight dot had stopped rendering entirely: the full point program multiplies fill alpha by the per-item
a_style.xfactor, the regular scatter draw moved to the simpler point program that never sets that constant attribute, and_drawHoverPointinherited its default of 0. It now sets every constant attribute and stroke uniform the program reads. Verified in real Chrome by counting highlight-coloured pixels on the presented canvas (0 → 520 around the hovered point) and pinned bytest_browser_nearest_hover_highlight_is_visible.Verified
