TikZ-PGF 中围绕钟形曲线的文本

TikZ-PGF 中围绕钟形曲线的文本

我想创建一个钟形曲线，并在其周围添加一些解释性文字。但是我无法在注释中添加换行符，也无法在 Latex 中获取有关预期寿命的两段文本。到目前为止，我自己的代码也如下所示。

谢谢！

编辑：换行符的问题解决了！但是，我仍然不明白如何让图表下方的箭头显示增加/减少的预期寿命

在此处输入图片描述

\documentclass{article}
\usepackage{pgfplots}
\begin{document}

\pgfmathdeclarefunction{gauss}{2}{%
  \pgfmathparse{1/(#2*sqrt(2*pi))*exp(-((x-#1)^2)/(2*#2^2))}%
}

\begin{tikzpicture}
\begin{axis}[
  no markers, domain=0:10, samples=1000,
  %axis lines*=left,
  axis y line=none,
  axis x line*=bottom,
  %xlabel=$x$, ylabel=$y$,
  every axis y label/.style={at=(current axis.above origin),anchor=south},
  every axis x label/.style={at=(current axis.right of origin),anchor=west},
  height=6.25cm, width=15cm,
  xtick=\empty, ytick=\empty,
  enlargelimits=false, clip=false, axis on top,
  grid = none
  ]
  \addplot [fill=cyan!20, draw=none, domain=6:7] {gauss(5,1.1)} \closedcycle;
 % \addplot [very thick,cyan!50!black] {gauss(4,1)};
  \addplot [very thick,cyan!50!black] {gauss(5,1.1)};


\draw [yshift=-0.6cm, latex-latex](axis cs:4,0) -- node [fill=white] {Value of liabilities} (axis cs:6,0);
\draw[cyan!35] (axis cs:5,0) -- (axis cs:5,0.4);

\node[coordinate,pin=45:{Attachment point}]
at (axis cs:6,0.2399) {};
\node[coordinate,pin=45:{Detachment point}]
at (axis cs:7,0.06945) {};
\node[coordinate,pin=180:{Expected value \\ of liabilities}]
at (axis cs:5,0.39) {};


\end{axis}

\end{tikzpicture}
\end{document}

这是一种方法，我给出name轴，并axis相对于其角在环境之后绘制箭头。

\documentclass{article}
\usepackage{pgfplots}
\begin{document}

\pgfmathdeclarefunction{gauss}{2}{%
  \pgfmathparse{1/(#2*sqrt(2*pi))*exp(-((x-#1)^2)/(2*#2^2))}%
}

\begin{tikzpicture}
\begin{axis}[
  name=myaxis, %%% <--- added
  no markers, domain=0:10, samples=100,
  %axis lines*=left,
  axis y line=none,
  axis x line*=bottom,
  %xlabel=$x$, ylabel=$y$,
  every axis y label/.style={at=(current axis.above origin),anchor=south},
  every axis x label/.style={at=(current axis.right of origin),anchor=west},
  height=6.25cm, width=15cm,
  xtick=\empty, ytick=\empty,
  enlargelimits=false, clip=false, axis on top,
  grid = none
  ]
  \addplot [fill=cyan!20, draw=none, domain=6:7] {gauss(5,1.1)} \closedcycle;
 % \addplot [very thick,cyan!50!black] {gauss(4,1)};
  \addplot [very thick,cyan!50!black] {gauss(5,1.1)};


\draw [yshift=-0.6cm, latex-latex](axis cs:4,0) -- node [fill=white] {Value of liabilities} (axis cs:6,0);
\draw[cyan!35] (axis cs:5,0) -- (axis cs:5,0.4);

\node[coordinate,pin=45:{Attachment point}]
at (axis cs:6,0.2399) {};
\node[coordinate,pin=45:{Detachment point}]
at (axis cs:7,0.06945) {};
\node[coordinate,pin={[align=center]180:Expected value \\ of liabilities}]
at (axis cs:5,0.39) {};

\end{axis}

% add arrows with labels
\draw [<-] (myaxis.south west) ++(0,-1cm) -- node[below,align=center]{Decreasing life\\expectancy} ++(2cm,0);
\draw [<-] (myaxis.south east) ++(0,-1cm) -- node[below,align=center]{Increasing life\\expectancy} ++(-2cm,0);
\end{tikzpicture}
\end{document}
