pgfplots: 정수만 있고 x축의 정수 자리에만 틱 표시

Question

xbar이런 다이어그램을 만들고 싶지만 설정하고 싶습니다.

• 정수만하단 x축(0.5, 1.5, 2.5, ... 없음) 그리고
• 정수 자리에만 틱 표시(0.5, 1.5, 2.5, ...에서는 틱 없음)

또 다른 문제도 있습니다: xmaxxtick={1,2,...,\n}1에서 '~400'(동일한 다이어그램 너비 사용)까지 진행되므로 (here \def\n{400}) 처럼 x를 명시적으로 설정하는 것은 좋지 않습니다 .
자동 적응형 x축 라벨 지정은 pgfplots괜찮지만 정수만 표시되어야 합니다.

나는에서 시도했다여기

% https://tex.stackexchange.com/a/286623/46023
xticklabel={%
        \pgfmathtruncatemacro{\IntegerTick}{\tick}%
        \pgfmathprintnumberto[verbatim,fixed,precision=3]{\tick}\tickAdjusted%
        \pgfmathparse{\IntegerTick == \tickAdjusted ? 1: 0}%
        \ifnum\pgfmathresult>0\relax$\IntegerTick$\else\fi%
},  

하지만 이 방법은 여전히 ​​틱을 설정합니다(0.5, 1.5, 2.5 등).

어떻게 해야 하나요?

Answer 1

어쩌면 이렇게?

• xtick지정된 범위 내의 정수에만 틱이 표시되도록 명시적으로 설정했습니다 .
• xtick 위치를 명시적으로 정의했으므로 조건부 xticklabel 코드를 제거하세요.

\usepackage{pgfplots}
\pgfplotsset{compat=1.18}

\begin{document}
\foreach \n in {1,...,6}{%%%%%%%%%%%%%%%%%
