将图适合 pgfplots 中的整个页面

Question

我使用 PGFPlots 创建图表并将其导出到我的主题演讲幻灯片中。我总是必须修剪导出的 pdf 文件的边。附件是此类图表的一个示例。我想知道是否有办法让情节自动适应 pdf 文件中的整个页面？

以下是生成图表的代码

\documentclass[a4paper]{article}

\usepackage{amsmath}
\usepackage{xcolor}
\usepackage{pgfplots}
\usepackage{pgfplotstable}%fitting functions
\usepackage{tikz}
\usetikzlibrary{tikzmark,patterns,pgfplots.fillbetween}

\pagestyle{empty}

\pgfkeys{/pgf/number format/.cd,fixed}

\pgfplotsset{compat=1.15}
\pgfplotsset{label style={font=\LARGE},
            tick label style={font=\LARGE}}

\pgfplotsset{error bars/.cd,
    x dir=both, x explicit,
    y dir=both, y explicit,
    }

\begin{document}


\begin{figure}
\centering
\begin{tikzpicture}
\begin{axis}[
    enable tick line clipping=false, % makes all ticks same width
    axis line style=semithick,
    width=14cm,
    height=7cm,
    x tick style={black,semithick},
    x label style=
        {at={(ticklabel cs:0.5)},anchor=near ticklabel},
    xlabel={$L$ [mm]},
    xmin=0,xmax=100,
    xtick={0,20,...,100},
    xtick pos=bottom,
    xtick align=outside,
    y tick style={black,semithick},
    y label style=
        {at={(ticklabel cs:0.5)},anchor=near ticklabel},
    ylabel={$F$ [N]},
    ymin=-0.05,ymax=0.2,
    ytick={-0.05,0,...,0.25},
    ytick pos=left,
    ytick align=outside,
]
    \addplot [only marks,mark=*,mark options={scale=0.5,red,fill=white}] file {LDPE_PETG_2.txt};

    \addplot [only marks,mark=*,mark options={scale=0.5,blue,fill=white}] file {LDPE-DOTO_PETG_2.txt};

\end{axis}
\end{tikzpicture}
\end{figure}

\end{document}
