In `realizeWidget` (~line 366, inside the `if needsBar` block), AFTER the + existing `addInfoIcon` / `addDetachButton` calls, add a duck-typed inject: + + ```matlab + % 260513-sfp — per-widget Y-limit-mode buttons (only widgets that + % implement setYLimitMode get this cluster; today that is FastSenseWidget + % but the duck-type check keeps the chrome generic for any future widget + % that exposes Y-rescale modes). + if ismethod(widget, 'setYLimitMode') + obj.addYLimitButtons_(widget); + end + ``` + + IMPORTANT: this MUST run inside the `needsBar` branch only — when a widget + skips chrome (no Description AND no DetachCallback) we have no bar to host + these buttons either. That's acceptable for v1 because every dashboard that + loads FastSenseWidget through DashboardEngine sets a DetachCallback, so + `needsBar` is always true for FastSenseWidget in practice. + + 2. Update the `needsBar` check (~line 363) to ALSO consider widgets that + expose setYLimitMode, so a dashboard that someday omits DetachCallback + still gets a bar for the YLimit buttons: + + ```matlab + needsBar = ~isempty(widget.Description) || ... + (~isempty(obj.DetachCallback) && ~isa(widget, 'DividerWidget')) || ... + ismethod(widget, 'setYLimitMode'); + ``` + + 3.

This is a pre-existing typo from earlier work, explicitly called out as out-of-scope in the plan's `` block (line ~170 of `260513-sfp-PLAN.md`): + +> NOTE: addInfoIcon already uses `barW - 28 - 28 - 4` (a typo from earlier work that treats button width as 28). For this plan, use 24+24+4 spacing for the new buttons. Do NOT "fix" the Info button — that is OUT OF SCOPE. + +`addYLimitButtons_` uses the correct 24+24+4 math relative to where Info SHOULD be, so the 0-px gap is inherited from the `addInfoIcon` typo. The user explicitly accepted this caveat at the checkpoint approval — the visual is acceptable and the buttons function correctly. Fixing it requires touching `addInfoIcon` (`bw - 24 - 24 - 4 - 4`), which would belong to a separate cleanup task. + +Logged at: `.planning/quick/260513-sfp-add-auto-y-limit-control-buttons-to-fast/deferred-items.md` (alongside the pre-existing `test_dashboard_range_selector_integration.m` Case 2 -batch failure). + +## Design Decisions + +1. **Y-mode dispatch lives inside `autoScaleY_(obj, y)`** rather than at the caller — keeps the method's public signature (`autoScaleY_(obj, y)`) byte-identical so `render`, `rebuildForTag_`, and any external callers keep working unchanged. The new dispatch is purely internal: after the existing precedence guards (`YLimits` pin / `UserZoomedY` / `FastSense.LiveViewMode == 'follow'` / not-rendered), the method branches on `obj.YLimitMode` — `locked` returns; `auto-all` swaps `y` for full tag data via `getYFromTagOrInline_`; `auto-visible` falls through to the existing min/max + threshold + padding code path. +2. **Duck-typed chrome injection** via `ismethod(widget, 'setYLimitMode')` rather than `isa(widget, 'FastSenseWidget')` — future widgets exposing a Y-rescale mode (e.g., a 2D heatmap with Z-clamp modes) opt in by simply implementing `setYLimitMode`, without touching `DashboardLayout`. Also extends `needsBar` so a duck-typed widget that omits `Description` and `DetachCallback` still gets a chrome strip to host its buttons. +3. **ASCII glyphs (`V`, `A`, `L`)** chosen to match existing Info (`i`) and Detach (`^`) buttons — Octave's font rendering on Linux for Unicode glyphs in `uicontrol String` is inconsistent across versions, and the existing WidgetButtonBar deliberately avoids Unicode. +4. **Default `YLimitMode = 'auto-visible'`** for backward compatibility — exactly reproduces pre-260513-sfp `autoScaleY_` behaviour. Existing dashboards load with no behavioural diff. `toStruct` omits `yLimitMode` when it equals the default, so JSON diffs of legacy dashboards stay invisible. +5. **`LiveViewMode='follow'` precedence preserved** — `autoScaleY_` short-circuits on `FastSense.LiveViewMode == 'follow'` BEFORE the new mode dispatch. This protects the 260513-ovt Follow-toggle semantics (Follow's explicit "freeze X+Y view, append only" intent still wins over any auto-rescale mode). Regression-guarded by `test_fastsense_follow_toggle.m` (10/10 pass). +6. **`UserZoomedY` cleared on explicit click** — without this, a user's prior mouse-zoom would latch `UserZoomedY = true` forever and silently defeat the V/A buttons. An explicit click on V or A is an explicit re-engage signal; clicking L while user-zoomed is also a clean freeze. +7. **`YLimits` numeric pin still wins** — explicit pinning via the `YLimits` property on the widget remains the highest-precedence mode (after the early-return guards). Old dashboards that pin Y explicitly keep their pinned range regardless of which V/A/L button is "active" visually. +8. **No new theme tokens** — `chooseYLimitActiveBg_` falls through `PressedBg` -> `SelectedBg` -> `AccentColor` -> brightened `ToolbarBackground`. Leaves a clean follow-up to add a proper `theme.PressedBg` field if reviewers prefer. + +## Out-of-Scope Follow-ups (not done, deliberately) + +- **Detached-mirror V/A/L cluster** — `DetachedMirror` uses its own figure-level `FastSenseToolbar` (not a `WidgetButtonBar`). Adding the cluster there would belong to a separate quick task that extends `FastSenseToolbar` rather than `DashboardLayout`. For v1 of this feature, the detached mirror retains the standard MATLAB axes-toolbar zoom controls plus `FastSenseToolbar`'s Follow/Live buttons, which is sufficient. +- **Symmetric-zero mode (a 4th button)** — explicit YAGNI for v1; trivial to add as a `'symmetric'` value in the `YLimitMode` validation switch. +- **`theme.PressedBg` field** — the `chooseYLimitActiveBg_` fallback chain works today; a proper theme token would be a clean follow-up. +- **`addInfoIcon` 28→24 px fix** — pre-existing typo, deliberately untouched per the plan's `` instruction; manifests as the 0-px gap between L and Info documented under Known Caveat. + +## Deviations from Plan + +- **Test file canRenderFigures_() guard** — the planned `usejava('desktop')` skip-on-headless guard was too strict for the rendered cases (they DO run under `matlab -batch` because they use offscreen `figure('Visible','off')`). Loosened to a `canRenderFigures_()` helper so the rendered cases execute under `-batch` / `-nodisplay` rather than skip. `test_fastsense_follow_toggle.m` keeps the stricter guard (it touches `uitoggletool`, which is genuinely incompatible with `-batch`). + +Tracked as `[Rule 3 - Test infra]` adjustment, internal to the test file only; no production-code impact. + +## Self-Check: PASSED + +Verified all claimed artifacts exist: + +- `libs/Dashboard/FastSenseWidget.m` (modified, contains `YLimitMode`, `setYLimitMode`, dispatch) — FOUND +- `libs/Dashboard/DashboardLayout.m` (modified, contains `addYLimitButtons_`) — FOUND +- `libs/Dashboard/DashboardWidget.m` (modified, contains extended `protectedTags`) — FOUND +- `tests/test_fastsense_widget_ylimit_modes.m` (created) — FOUND +- Commit `4db9138` in `git log --oneline` — FOUND +- Commit `cc18c7f` in `git log --oneline` — FOUND +- Commit `a9cc181` in `git log --oneline` — FOUND diff --git a/.planning/quick/260513-sfp-add-auto-y-limit-control-buttons-to-fast/deferred-items.md b/.planning/quick/260513-sfp-add-auto-y-limit-control-buttons-to-fast/deferred-items.md new file mode 100644 index 00000000..d8cf72cf --- /dev/null +++ b/.planning/quick/260513-sfp-add-auto-y-limit-control-buttons-to-fast/deferred-items.md @@ -0,0 +1,35 @@ +# Deferred Items — 260513-sfp + +Out-of-scope discoveries logged during execution per the SCOPE BOUNDARY +rule.
