使用 pgfplots 仅显示第一个刻度标签

Question

我正在使用 pgfplots 绘制简单函数。我的轴设置如下：

\documentclass{standalone}
\usepackage{pgfplots}

\begin{document}
\begin{tikzpicture}
\begin{axis}[
    xmin=-30,xmax=30,
    ymin=-30,ymax=30,
    grid=both,
    axis lines=middle,
    xtick distance=4,
    ytick distance=4,
    enlargelimits={abs=0.5},
    axis line style={latex-latex},
    ticklabel style={font=\scriptsize}
]
\end{axis}
\end{tikzpicture}
\end{document}

由此产生了如下结果：

我的问题是，许多这些刻度标签都是多余的。我怎样才能仅显示和处的刻度x = 4标签y = 4？

要明确的是，我想保留刻度线本身和网格线，我只想去掉数字8、12等、和-4、、等-8。-12

Answer 1

另一种方法是将以下选项添加到您的axis环境中：

xticklabels={},
yticklabels={},
extra x ticks={4},
extra y ticks={4},

前两行隐藏所有刻度标签，后两行添加额外的刻度。以下代码

\documentclass{standalone}
\usepackage{pgfplots}

\begin{document}
\begin{tikzpicture}
\begin{axis}[
    xmin=-30,xmax=30,
    ymin=-30,ymax=30,
    grid=both,
    axis lines=middle,
    xtick distance=4,
    ytick distance=4,
    enlargelimits={abs=0.5},
    axis line style={latex-latex},
    ticklabel style={font=\scriptsize},
    xticklabels={},
    extra x ticks={4},
    yticklabels={},
    extra y ticks={4},
]
\end{axis}
\end{tikzpicture}
\end{document}

干得好：

\documentclass{standalone}
\usepackage{pgfplots,tikz}

\begin{document}

  \begin{tikzpicture}
  \begin{axis}[
  xmin=-30,xmax=30,
  ymin=-30,ymax=30,
  grid=both,
  axis lines=middle,
  xtick distance=4,
  ytick distance=4,
  xtick={-28,-24,-20,-16,-12,-8,-4,0,4,8,12,16,20,24,28},
  xticklabels={,,,,,,,,4,,,,,,},
  ytick={-28,-24,-20,-16,-12,-8,-4,0,4,8,12,16,20,24,28},
  yticklabels={,,,,,,,,4,,,,,,},
  enlargelimits={abs=0.5},
  axis line style={latex-latex},
  ticklabel style={font=\scriptsize}
  ]
  {}\end{axis};
  \end{tikzpicture}



\end{document}
