图形：在曲线之间绘制区域时，Tikz 图片放置不正确

Question

我正在尝试使用方法大纲 图形：曲线之间的面积 创建两条曲线之间面积的图表以插入解决方案表。但是，当我这样做时，框的位置不正确。tikzpicture 最终比它应该的位置高得多，而不是排成一行，因此覆盖了文本或放置在其上方的其他图片。我的代码如下：

\documentclass[11pt]{article}

\usepackage{tikz}
\usepackage{pgfplots}

\usepgfplotslibrary{fillbetween}
\usetikzlibrary{patterns}

\begin{document}
The box for the tikzpicture appears to be much higher than it should be.\\
{\begin{tikzpicture}[scale=0.75]
\begin{axis}[
xmin=0,xmax=5,
    ymin=-1, ymax=6,
        xtick = {-1,1},
    ytick = {1,2,3,4,5,6},
    axis lines=center,
    axis line style = <->,
        ticklabel style = {font=\small}
]

\addplot[name path=F,domain={0:5}] {x};
\addplot[name path=G,domain={0:5}] {(x-2)^2};
\addplot[pattern=north west lines, pattern color=gray!50]fill between[of=F and G, soft clip={domain=1:4}];
\end{axis}
\end{tikzpicture}}
\end{document}

正如我在在问题下方评论 我认为这是一个错误，我已将其报告给PGFPlots 追踪器。

有一种解决方法可以得到所需的结果。查看代码中的注释以了解如何操作。

\documentclass[11pt]{article}
\usepackage{pgfplots}
    \usetikzlibrary{
        patterns,
        pgfplots.fillbetween,
    }
\begin{document}
The box for the tikzpicture appears to be much higher than it should be.

\begin{tikzpicture}[
% this line causes the mess ...
%    scale=0.75,
]
    \begin{axis}[
        % ... as a workaround just scale the default axis `width' directly with
        % the factor to get the desired result
        width=0.75*\axisdefaultwidth,
        xmin=0,     xmax=5,
        ymin=-1,    ymax=6,
        xtick={-1,1},
        ytick={1,2,3,4,5,6},
        axis lines=center,
        axis line style=<->,
        ticklabel style={font=\small}
    ]
        \addplot [name path=F,domain={0:5}] {x};
        \addplot [name path=G,domain={0:5}] {(x-2)^2};
        \addplot [
            pattern=north west lines,
            pattern color=gray!50,
        ] fill between [
            of=F and G,
            soft clip={domain=1:4},
        ];
    \end{axis}
\end{tikzpicture}
\end{document}
