tick align=outside我对 pgfplots 中和的奇怪行为感到困惑\ttfamily。这是我的代码：
\documentclass{standalone}
\usepackage{tikz,pgfplots}
\usepackage{pgfplotstable}
\usepgfplotslibrary{fillbetween}
\tikzset{every picture/.style={/utils/exec={font=\ttfamily}}}
\begin{document}
\pgfplotsset{
width=15cm, height=7cm, compat=1.3
}
\definecolor{fillColor}{RGB}{125, 185, 250}
\pgfmathdeclarefunction{gauss}{2}{%
\pgfmathparse{1/(#2*sqrt(2*pi))*exp(-((x-#1)^2)/(2*#2^2))}%
}
\begin{tikzpicture}
\begin{axis}[axis lines = left,
tick align=outside,
every axis x label/.style={at={(current axis.right of origin)},anchor=north east},
every axis y label/.style={at={(current axis.north west)},above=0.5mm},
xlabel=$x$,
ylabel=$f(x)$,
%ylabel style={rotate=-90},
mark=none,
domain=-1.9:7,
samples=100,
smooth, % All plots: from -2:2, 50 samples, smooth, no marks
axis lines=left, % the * suppresses the arrow tips
enlargelimits=upper] % extend the axes a bit to the right and top
\path [name path=B]
(\pgfkeysvalueof{/pgfplots/xmin},0) --
(\pgfkeysvalueof{/pgfplots/xmax},0);
\addplot [color=fillColor!125, name path=A] {gauss(0,0.5)};
\addplot [fillColor!50] fill between [of = A and B];
\node at (axis cs:1,0.8) {$\mathcal{N}(0,0.5)$};
\addplot [color=fillColor!100, name path=C] {gauss(2,0.75)};
\addplot [fillColor!25] fill between [of = C and B];
\node at (axis cs:3.,0.55) {$\mathcal{N}(2,0.75)$};
\addplot [color=fillColor!75, name path=D] {gauss(4,1)};
\addplot [fillColor!10] fill between [of = D and B];
\node at (axis cs:5.,0.4) {$\mathcal{N}(4,1)$};
\end{axis}
\end{tikzpicture}
\end{document}
这让我得到了这个数字：
但我不明白为什么刻度线不在轴外，以及为什么字体不是 \ttfamily。欢迎提出任何想法！
答案1
- 如果您使用的是旧版本
pgfplots，我强烈建议您将其更新至最新版本 1.18。 - 图表轴声明了两次。删除第二个。
\pgfplotsset（参见下面的 MWE） - 看看以下 MWE 是否给出了您想要的结果：
\documentclass{standalone}
\usepackage{pgfplots}
\usepackage{pgfplotstable}
\usepgfplotslibrary{fillbetween}
\pgfplotsset{compat=1.18,
width=15cm, height=7cm,
%ticklabel style = {font=\ttfamily}
}
\begin{document}
\definecolor{fillColor}{RGB}{125, 185, 250}
\pgfmathdeclarefunction{gauss}{2}{%
\pgfmathparse{1/(#2*sqrt(2*pi))*exp(-((x-#1)^2)/(2*#2^2))}%
}
\begin{tikzpicture}
\begin{axis}[
axis lines = left,
tick align=outside,
xlabel=$x$, xlabel style={at ={(1,0)},anchor=north east},
ylabel=$f(x)$, ylabel style={at ={(0,1)}, rotate=270, anchor=south},
mark=none,
domain=-1.9:7,
samples=100,
smooth, % All plots: from -2:2, 50 samples, smooth, no marks
enlargelimits=upper] % extend the axes a bit to the right and top
\path [name path=B]
(\pgfkeysvalueof{/pgfplots/xmin},0) --
(\pgfkeysvalueof{/pgfplots/xmax},0);
\addplot [color=fillColor!125, name path=A] {gauss(0,0.5)};
\addplot [fillColor!50] fill between [of = A and B];
\node at (axis cs:1,0.8) {$\mathcal{N}(0,0.5)$};
\addplot [color=fillColor!100, name path=C] {gauss(2,0.75)};
\addplot [fillColor!25] fill between [of = C and B];
\node at (axis cs:3.,0.55) {$\mathcal{N}(2,0.75)$};
\addplot [color=fillColor!75, name path=D] {gauss(4,1)};
\addplot [fillColor!10] fill between [of = D and B];
\node at (axis cs:5.,0.4) {$\mathcal{N}(4,1)$};
\end{axis}
\end{tikzpicture}
\end{document}
