Para escalar la curva correctamente, necesita el número total de puntos de datos dividido por los puntos de datos para la barra máxima en la distribución del histograma (aquí se muestra como 40/12 y 40/2). ¿Hay alguna manera de calcular esto? Puedo obtener el primero, pero no el último.
Gracias por cualquier ayuda,
Juan
No sé cómo obtener los recuentos, pero suponiendo que la escala sea apropiada, puede pedirle a la casilla del eje el valor máximo de la escala con el mensaje << Obtener máximo.
