调整标签箭头和正态分布曲线的大小

我想要如下图所示的图表：
在此处输入图片描述
到目前为止，我有以下 MWE：

\documentclass[border=2cm]{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.8}
\begin{document}
    
    \pgfmathdeclarefunction{gauss}{3}{%
        \pgfmathparse{1/(#3*sqrt(2*pi))*exp(-((#1-#2)^2)/(2*#3^2))}%
    }

    \begin{tikzpicture}[every pin edge/.style={<-},]
        \begin{axis}[
            no markers, 
            domain=0:6, 
            samples=100,
            ymin=0,
            axis lines*=left, 
            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=5cm, 
            width=12cm,
            xtick=\empty, 
            ytick=\empty,
            enlargelimits=false, 
            clip=false, 
            axis on top,
            grid = major,
            hide y axis
            ]
            
            \begin{scope}[yshift=-\pgflinewidth]
                \clip (axis cs:1,0) rectangle (axis cs:2,0.24);
                \addplot [draw=none,fill=orange] {gauss(x, 3, 1)};
            \end{scope}
            
            \addplot [very thick,cyan!50!black] {gauss(x, 3, 1)};
            \pgfmathsetmacro\valueB{gauss(1,1,7)}
            \pgfmathsetmacro\valueA{gauss(1,1,1.65)}
            \pgfmathsetmacro\valueC{gauss(1,1,1)}
            
            \draw [very thick, blue]  (axis cs:1,0) -- (axis cs:1,\valueB);
            \draw [very thick, blue]  (axis cs:2,0) -- (axis cs:2,\valueA);
            \draw [very thick, blue]  (axis cs:3,0) -- (axis cs:3,\valueC);
            
            \node[below] at (axis cs:3,0)  {0}; 
            \node[coordinate,pin=86:{Probability distribution of expected returns in the set period}]
            at (axis cs:4,0.25) {};
            \node[coordinate,pin=100:{$\alpha$}]
            at (axis cs:1.4,0.1) {};
            \node[coordinate,pin=270:{Expected Shortfall}]
            at (axis cs:1.6,0) {};
            \node[coordinate,pin=86:{Value at Risk}]
            at (axis cs:2,0) {};
        \end{axis}
        
    \end{tikzpicture}
\end{document}

虽然正态曲线的大小、标记箭头的大小、标记箭头的位置和标记文本（例如收益分布的概率……文本延伸到右侧，这是我不希望看到的）需要进行一些调整，但它产生的效果接近我想要的效果。下图显示了使用 MWE 获得的输出：

要更改箭头提示，我建议加载arrows.meta库。然后你就可以使用了every pin edge/.style={Stealth-}。

要将图钉标签拆分为多行，必须将其对齐。您可以在同一位置对图钉位置进行其他调整：

\node[coordinate, 
    pin={[align=right, anchor=south, pin distance=5mm]
      above right:{Probability distribution\\of Returns expected\\in the set period}}]
  at (axis cs:4,0.25) {};

您可以使用xscale它来扩大情节范围。

以下是代码：

\documentclass[border=2cm]{standalone}
\usepackage{pgfplots}
\usetikzlibrary{arrows.meta}
\pgfplotsset{compat=1.8}
\begin{document}
    
    \pgfmathdeclarefunction{gauss}{3}{%
        \pgfmathparse{1/(#3*sqrt(2*pi))*exp(-((#1-#2)^2)/(2*#3^2))}%
    }

    \begin{tikzpicture}[every pin edge/.style={Stealth-},]
        \begin{axis}[xscale=1.5,
            no markers, 
            domain=0:6, 
            samples=100,
            ymin=0,
            axis lines*=left, 
            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=5cm, 
            width=12cm,
            xtick=\empty, 
            ytick=\empty,
            enlargelimits=false, 
            clip=false, 
            axis on top,
            grid = major,
            hide y axis
            ]
            
            \begin{scope}[yshift=-\pgflinewidth]
                \clip (axis cs:1,0) rectangle (axis cs:2,0.24);
                \addplot [draw=none,fill=orange] {gauss(x, 3, 1)};
            \end{scope}
            
            \addplot [very thick,cyan!50!black] {gauss(x, 3, 1)};
            \pgfmathsetmacro\valueB{gauss(1,1,7)}
            \pgfmathsetmacro\valueA{gauss(1,1,1.65)}
            \pgfmathsetmacro\valueC{gauss(1,1,1)}
            
            \draw [very thick, blue]  (axis cs:1,0) -- (axis cs:1,\valueB);
            \draw [very thick, blue]  (axis cs:2,0) -- (axis cs:2,\valueA);
            \draw [very thick, blue]  (axis cs:3,0) -- (axis cs:3,\valueC);
            
            \node[below] at (axis cs:3,0)  {0}; 
            \node[coordinate, pin={[align=right, anchor=south, pin distance=5mm]above right:{Probability distribution\\of Returns expected\\in the set period}}]
            at (axis cs:4,0.25) {};
            \node[coordinate,pin=100:{$\alpha$}]
            at (axis cs:1.4,0.1) {};
            \node[coordinate,pin=270:{Expected Shortfall}]
            at (axis cs:1.6,0) {};
            \node[coordinate,pin=86:{Value at Risk}]
            at (axis cs:2,0) {};
        \end{axis}
        
    \end{tikzpicture}
