## Contexto
|
|
|
|
Fase 10 del roadmap del tables playground. Drill-down basico ya implementado
|
|
(`make_drill_filter` + chip de filtro en stage previo). Falta granularidad de
|
|
zoom, presets rapidos, click sobre elementos del chart, historial de drill y
|
|
row inspector.
|
|
|
|
## Cambios
|
|
|
|
### 1. Zoom granularity sobre cols Date
|
|
|
|
- Detectar col tipo `Date` en breakout.
|
|
- Combo en chip de breakout: "year / month / week / day / hour".
|
|
- Pure fn `truncate_date_cpp_core(date_str, granularity) -> string`.
|
|
- Stage 1 con breakout `<col>:month` agrega valores formateados al granular.
|
|
- TQL: `breakout = {"col:month"}` (sufijo despues de `:`).
|
|
- Auto-detect granularity inicial: si rango > 2 anios -> year; > 60 dias -> month; > 14 dias -> week; resto -> day.
|
|
|
|
### 2. Quick filter presets
|
|
|
|
- Boton "Presets" en chip row de filtros.
|
|
- Menu con:
|
|
- "Top 10 by <col>" (auto-sugiere col numerica)
|
|
- "Last 7 / 30 / 90 dias" (si hay col Date)
|
|
- "Exclude nulls in <col>"
|
|
- "Non-zero only"
|
|
- Aplica como filtros al stage activo.
|
|
|
|
### 3. Click-to-drill sobre chart elements
|
|
|
|
- Bar/Column/Pie/Funnel: click en elemento -> `make_drill_filter(col_idx, value)` -> push filter en stage previo, `active_stage--`.
|
|
- Scatter/Bubble: click en punto -> filter por X y Y rangos cercanos (snap to nearest data point) o muestra row inspector.
|
|
- Heatmap: click en celda -> filtro por par (row, col).
|
|
- ImPlot api: `ImPlot::IsPlotHovered() + GetPlotMousePos()`. Hit-test propio para barras.
|
|
|
|
### 4. Drill history (back/forward)
|
|
|
|
- Pila de `DrillStep { stage_idx, filter_added }` en `UiState.drill_history`.
|
|
- Botones `<` `>` en breadcrumb para back/forward.
|
|
- TQL preserva el stage agrupado pero no la history (es UI state efimero).
|
|
|
|
### 5. Row inspector
|
|
|
|
- Click derecho sobre row de tabla o punto de chart -> popup modal con todas las cols + valores de la fila.
|
|
- Incluye cols ocultas.
|
|
- Solo lectura. Boton "Copy as TSV" + "Filter by this row".
|
|
|
|
### 6. Drill-up: vuelve un stage atras sin perder filtros nuevos
|
|
|
|
- Boton `<` en breadcrumb del stage previo: pushdown del filter actual al stage anterior + active--.
|
|
- Inverso de drill-down. Usuario navega la jerarquia sin perder camino.
|
|
|
|
## Tests
|
|
|
|
- `truncate_date_cpp_core` para granularities (round-trip por fecha conocida).
|
|
- Pure fn de quick filter presets (build `vector<Filter>` desde preset id).
|
|
- Round-trip TQL con breakout sufijo `:month`.
|
|
|
|
## No-objetivos
|
|
|
|
- Map drill (lat/lng -> region) — fuera de scope.
|
|
- Cross-filter entre paneles (click en panel A filtra panel B) — fase futura.
