# line_plot
|
|
|
|
Wrapper atomico sobre `ImPlot::PlotLine` configurado para visualizacion estatica.
|
|
|
|
## v1.1
|
|
|
|
- **Altura explicita** (`height`) — evita vibracion en contenedores con `AutoResizeY`.
|
|
- **Ejes pineados** con `plot_static::kAxisFlags` + `ImPlotCond_Always` calculados a partir de los extremos de `xs`/`ys` con 5% de headroom en Y.
|
|
- **Sin inputs, sin auto-fit** — ver `viz/plot_static.h`.
|
|
|
|
Soporta `float` y `double`.
|
|
|
|
## Capability growth log
|
|
|
|
- v1.2.0 (2026-05-18) — Overloads `(..., y_min, y_max, height)` para series con dominio conocido (CPU%/RAM% -> 0,100). Mantiene los overloads de auto-fit historico intactos. Tipos float y double.
|
|
- v1.3.0 (2026-05-18) — Overloads `(..., x_min, x_max, y_min, y_max, height)` que pinea AMBOS ejes. Util para ventanas temporales fijas (ej. ultimos 5 min): xs en [0, 300], el grafico NO se aplasta al variar count durante warmup.
