Tenga en cuenta los comandos \addlegendentry en el siguiente código. En el momento en que los habilito, aparece un error que no puedo manejar. ¿Cómo construyo correctamente la leyenda de este gráfico que funciona de otra manera?

Respuesta1
El error ( Missing } inserted.) al intentar usar \addlegendentryes causado por el uso de la opción forget plot. Esta opción se utiliza para excluir los gráficos de la leyenda, lo que choca con el comando \addlegendentry.
Eliminar forget plotde las opciones de la trama soluciona el problema.
