Crea una línea de tiempo curva en Tex

Estoy intentando crear una línea de tiempo que incluya 24 puntos de tiempo colocados en una flecha curva de la siguiente manera:

Tengo una versión de una flecha recta (de @Gonzalo Medina), pero es más larga que el ancho de la página, por lo que quiero tener una línea de tiempo curva como la anterior. Me gustaría pedir su ayuda. Muchas gracias.

Árbitro.:¿Cómo puedo hacer una línea de tiempo estándar?[agregado por la comunidad]

Respuesta1

Para empezar...

  • Para una flecha en varias líneas, sugiero usar la arrows.metabiblioteca.

     % p.221
 %\usetikzlibrary {arrows.meta}
 \tikz \draw [line width=1ex,
 {Triangle Cap[reversed]-{Latex[length=0pt +2]}}]
 (0,0) -- (1,0);

  • Para la etiqueta tarea1, tarea2... uso \node alsocon label distancein\tikzset

EDITAR: Con una forma más redondeada, uso a circle(con a clip) y agrego 2 argumentos en el bar arrown.° 1 para el inicio y el n.° 2 para el final.

  • Agrego una longitud \arrowvseppara la distancia entre las flechas.

Me gustó este tipo de gráfico y vi que se prestaba a las soluciones que tengo para imprimir etiquetas masivas, el camino se dibuja en partes comenzando desde la cola hacia la cabeza, cuando la number of sectionsfila alcanza un valor específico, la curva respectiva es se dibuja y se dibujan los tramos en sentido contrario, luego de completar el doble del valor del número de tramos, se dibuja la otra curva y se pone a cero el contador, haciendo así que el camino crezca automáticamente, finalmente se detiene el cabezal que era necesario acondicionar. los dibujos al ingreso de datos de texto, que en lugar de dibujar el cuerpo dibuja la cabeza cuando esta el texto endy en ese caso hay 2 opciones si va o regresa, si regresa debe colocar reverse, para que dibuje el voy en dirección contraria, aprendí mucho haciendo esto, tomando cosas de aquí y de allá, por eso lo comparto y por el fin de semana en casa.

Hago este tipo de organización de código porque los datos se pueden ordenar en filas, y en el caso de generar etiquetas puedo obtenerlas rápidamente usando una hoja de datos como Excel, por ejemplo, exportando su respectivo formato de código tikz en un cuadro final.

Algunos de los textos los hice completar con un chatbot con ciertos temas, espero que no sean incómodos.
