+- 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.
