Intento interpolar estas curvas y lo que obtengo no es muy bonito:

El resultado :
¿Cómo puedo suavizar estas curvas para que parezcan más reales? Y también me gustaría agregar los números encerrados en un círculo.
Respuesta1
He aquí una manera de hacerlo. Llaves:
- eliminando código innecesario de su ejemplo
- reemplazando
--porto[out=,in=] - poniendo un punto intermedio para la curva azul
- poner etiquetas al final de cada curva con algunas variantes para cambiarla
También puedes utilizar controls, otro enfoque mediante curvas de Bézier. Encuentro efectos tomás fáciles de visualizar.
Sugiero dibujar sus gráficos en archivos separados usando class standaloneE incluyendo dichos pdf a través del paquete graphicx. Ver aquí paraun ejemplo, mientras que sugerí hacerlovarias veces (encontrar más).
