Pgfplots 和 beamer：如何用斜线（阴影）作为图案填充曲线下的区域？

这是一个后续问题杰克的解决方案到那篇文章。

虽然我得到了杰克的解决方案在 LaTeX 文档中可以完美运行，但在 中却不行beamer。这是 Jake 的代码，但使用beamer：

\documentclass{beamer}
\usepackage{tikz}
\usetikzlibrary{patterns}
\usepackage{pgfplots}

\begin{document}

\begin{frame}
    \begin{tikzpicture}
    \tikzset{
        hatch distance/.store in=\hatchdistance,
        hatch distance=10pt,
        hatch thickness/.store in=\hatchthickness,
        hatch thickness=2pt
    }

    \makeatletter
    \pgfdeclarepatternformonly[\hatchdistance,\hatchthickness]{flexible hatch}
    {\pgfqpoint{0pt}{0pt}}
    {\pgfqpoint{\hatchdistance}{\hatchdistance}}
    {\pgfpoint{\hatchdistance-1pt}{\hatchdistance-1pt}}%
    {
        \pgfsetcolor{\tikz@pattern@color}
        \pgfsetlinewidth{\hatchthickness}
        \pgfpathmoveto{\pgfqpoint{0pt}{0pt}}
        \pgfpathlineto{\pgfqpoint{\hatchdistance}{\hatchdistance}}
        \pgfusepath{stroke}
    }

    \begin{axis}[
        xmin=-4,xmax=4,
        xlabel={z},
        ymin=0,ymax=1,
        axis on top,
        legend style={legend cell align=right,legend plot pos=right}] 
    \addplot[color=red,domain=-4:4,samples=100] {1/sqrt(2*pi)*exp(-x^2/2)};
    \addlegendentry{z}
    \addplot+[mark=none,
        domain=0:1,
        samples=100,
        pattern=flexible hatch,
        area legend,
        pattern color=red]{1/sqrt(2*pi)*exp(-x^2/2)} \closedcycle;
    \addlegendentry{Interval 1}
    \addplot+[mark=none,
        domain=-2:-0.5,
        samples=100,
        pattern=flexible hatch,
        hatch distance=5pt,
        hatch thickness=0.5pt,
        draw=blue,
        pattern color=cyan,
        area legend]{1/sqrt(2*pi)*exp(-x^2/2)} \closedcycle;    
        \addlegendentry{Interval 2}
    \end{axis}
\end{tikzpicture}
\end{frame}
\end{document}

系统似乎永远无法完成编译。我不确定这是否只是我的系统的问题，还是更普遍的问题？

同时，Marco 的解决方案那里确实有工作beamer。

只需将fragile选项添加到框架即可：

\documentclass{beamer}
\usepackage{tikz}
\usetikzlibrary{patterns}
\usepackage{pgfplots}

\begin{document}

\begin{frame}[fragile]
    \begin{tikzpicture}
    \tikzset{
        hatch distance/.store in=\hatchdistance,
        hatch distance=10pt,
        hatch thickness/.store in=\hatchthickness,
        hatch thickness=2pt
    }

    \makeatletter
    \pgfdeclarepatternformonly[\hatchdistance,\hatchthickness]{flexible hatch}
    {\pgfqpoint{0pt}{0pt}}
    {\pgfqpoint{\hatchdistance}{\hatchdistance}}
    {\pgfpoint{\hatchdistance-1pt}{\hatchdistance-1pt}}%
    {
        \pgfsetcolor{\tikz@pattern@color}
        \pgfsetlinewidth{\hatchthickness}
        \pgfpathmoveto{\pgfqpoint{0pt}{0pt}}
        \pgfpathlineto{\pgfqpoint{\hatchdistance}{\hatchdistance}}
        \pgfusepath{stroke}
    }

    \begin{axis}[
        xmin=-4,xmax=4,
        xlabel={z},
        ymin=0,ymax=1,
        axis on top,
        legend style={legend cell align=right,legend plot pos=right}] 
    \addplot[color=red,domain=-4:4,samples=100] {1/sqrt(2*pi)*exp(-x^2/2)};
    \addlegendentry{z}
    \addplot+[mark=none,
        domain=0:1,
        samples=100,
        pattern=flexible hatch,
        area legend,
        pattern color=red]{1/sqrt(2*pi)*exp(-x^2/2)} \closedcycle;
    \addlegendentry{Interval 1}
    \addplot+[mark=none,
        domain=-2:-0.5,
        samples=100,
        pattern=flexible hatch,
        hatch distance=5pt,
        hatch thickness=0.5pt,
        draw=blue,
        pattern color=cyan,
        area legend]{1/sqrt(2*pi)*exp(-x^2/2)} \closedcycle;    
        \addlegendentry{Interval 2}
    \end{axis}
\end{tikzpicture}
\end{frame}
\end{document}

添加[fragile]后，\begin{frame}[fragile] 当涉及到代码时，LaTeX-Tikz 通常会挂起，并且 [脆弱] 它会被省略。
