我一直在寻找问题的答案，但似乎找不到。x 轴刻度没有显示最小/最大 tikz，我不明白为什么。
如您所见，最大 x-as 值 -120 和 +120 根本没有显示。相反，它停在 -100 和 100。如何修复此问题？

答案1
我建议使用xtick={-120,-80,...,120}。请注意，xticklabel style={/pgf/number format/1000 sep={}}鉴于X您正在使用的范围。

我想，实现您想要的最简单方法是添加xtick distance=30（或使用类似的值）选项axis。

\pgfplotsset{compat=1.3}
\begin{document}
\begin{tikzpicture}
\begin{axis}[
xmin=-120,xmax=120,
ymin=0, ymax=15,
xlabel=Event-time (trading days),
ylabel= $\overline{CAR}$ (\%),
xtick distance=30, % <-- added
]
% for simplicity changed your data
\addplot [blue,domain=-120:120] {15*rnd};
\end{axis}
\end{tikzpicture}
