Aparte de las dificultades para codificar el indicador :), creo que se vuelve a pintar porque la cuadrícula se calcula con el máximo y mínimo de todos los tiempos y se adapta en tiempo real, para que siempre obtenga una precisión perfecta del pasado. ¿Ya lo has usado con éxito? (y en tiempo real?).
