Posición de las barras de error en gráficos de barras en TiKZ

Question

¡Ayuda! Parece que no puedo obtener la posición de las barras de error justo encima de cada barra. Además, por alguna razón, mi leyenda también parece estar fuera de lugar.

Answer 1

No he encontrado una forma óptima, pero está funcionando en este ejemplo. Esta es una lista de mejoras:

1. Me cambié xscale = 1.45a width=12cm, height=6cm.
2. Agregué xshiftcon dimensión adivinada entre las opciones del error bar style(dos veces).
3. Comenté el inputencpaquete y decodifiqué caracteres diacríticos en cadenas TeX (dos veces), ahora el archivo se puede ejecutar con todos latexlos formatos principales, por ejemplo, mediante lualatex sample.tex.

Adjunto el resultado de mis esfuerzos y una vista previa del archivo PDF.
