0 位置处的标记不显示

Question

在下面的代码中，为什么 0 刻度标记不显示？

\documentclass{beamer}
\beamertemplatenavigationsymbolsempty
\usepackage{tikz}
\usepackage{pgfplots}
\begin{document}
\begin{frame}[fragile,t]
\frametitle{1}
\begin{tikzpicture}[scale=.9, transform shape]
\begin{axis}[axis lines=center,axis line style={black, thick,-latex},
 tick style={line width=.04cm, color=black, line cap=round},
 font=\normalsize,color=black,
 xmin=0,xmax=64,
 xtick={0,16,32},xticklabels={0,16,32},
 ymin=0,ymax=16,
 ytick={0,4,8},yticklabels={0,4,8},
 tickwidth=.2cm,
 xlabel={P}, xlabel style={right},
 ylabel={M}, ylabel style={above},
 xticklabel style={inner xsep=0cm, xshift=0cm,yshift=-.1cm},
 yticklabel style={inner ysep=0cm,xshift=-.1cm,yshift=0cm},
 samples=200]
\end{axis}
\end{tikzpicture}
\end{frame}
\end{document}

Answer 1

因此，根据您的（神秘消失的）评论，您想要：

• 显示0刻度标签
• 不显示0刻度线
• 将轴标签放置在轴的末端

代码：

\documentclass{beamer}
\beamertemplatenavigationsymbolsempty
\usepackage{tikz}
\usepackage{pgfplots}
\begin{document}
\begin{frame}[fragile,t]
\frametitle{1}
\begin{tikzpicture}[scale=.9, transform shape]
\begin{axis}[
    axis y line=left,
    axis x line=bottom,
    axis line style={black, thick,-latex},
    tick style={line width=.04cm, color=black, line cap=round},
    font=\normalsize,
    color=black,
    xmin=0,
    xmax=64,
    xtick={16,32},
    extra x ticks = {0},
    extra y ticks= {0},
    extra tick style={tick style={draw=none}},
    ymin=0,
    ymax=16,
    ytick={4,8},
    tickwidth=.2cm,
    xlabel={P}, 
    every axis x label/.style={
        at = {(ticklabel* cs:1)},
        anchor = west
    },
    ylabel={M}, 
    every axis y label/.style={
        at = {(ticklabel* cs:1)},
        anchor = south
    },
    xticklabel style={inner xsep=0cm, xshift=0cm,yshift=-.1cm},
    yticklabel style={inner ysep=0cm,xshift=-.1cm,yshift=0cm},
    samples=200
]
\end{axis}
\end{tikzpicture}
\end{frame}
\end{document}

结果：
