Pregunta de seguimiento deDibujar flechas desde diferentes bordes del nodo/cuadro de decisión
El problema que tengo parece bastante simple, pero no pude encontrar una solución en los archivos ni en ningún otro lugar. El resultado de mi .texarchivo es el siguiente diagrama de flujo:
Quiero agregar el texto "No" en la línea vertical que emerge del cuadro de decisión situado más abajo a la izquierda (con el texto "Verificar sobrecargas de línea"). También se puede colocar en la línea horizontal de manera que quede justo debajo de "Sí".
Agregué el texto "{No}" en algunos lugares, pero todos generan errores de compilación. ¿Alguien puede mostrarme la forma correcta de hacer que esto funcione?
