关于图表上的刻度的问题

x我正在尝试制作一个带有网格背景的图表。我希望它是标准窗口大小，但我只希望轴和轴上的 -10 和 10 旁边有数字y。我正在使用此代码

\begin{tikzpicture}
\begin{axis}[
  axis lines=middle,
  grid=major,
  xmin=-10,
  xmax=10,
  ymin=-10,
  ymax=10,
  xlabel=$x$,
  ylabel=$y$,
  xtick={-10,...,10},
  ytick={-10,...,10},
  tick style={very thick},
  legend style={
  at={(rel axis cs:0,1)},
  anchor=north west,draw=none,inner sep=0pt,fill=gray!10}
]
\addplot[domain=-3:3,blue,thick,samples=100,<->] {x^2};
\addplot[holdot] coordinates{(0,0)(4,4)(6,-5)};
\addplot[soldot] coordinates{(4,16)(6,6)(10,-5)};
%%\addlegendentry{$y=x^2$}
%%\addplot[domain=0:4,blue,] {x*x};
\addplot[domain=4:6,blue,] {x};
\addplot[domain=6:10,blue] {-5};
\end{axis}
\end{tikzpicture}

当我改变xtick={-10,...,10},网格时，其他所有不-10或的刻度也会消失10

我怎样才能使勾号存在但没有数字呢？

更新：这是修复原始问题的更新版本，但现在我正在尝试找出 x 轴、y 轴标签的良好位置

\begin{tikzpicture}
\centering
\begin{axis}[
  axis lines=middle,
  grid=major,
  xmin=-10,
  xmax=10,
  ymin=-10,
  ymax=10,
  xlabel style ={at={(1,0.5)},above right},
  ylabel style ={at={(0.5,1)},above right},
  xtick={-10,...,10},
  xticklabels={},    %% no x tick labels
  ytick={-10,...,10},
  yticklabels={},    %% no y tick labels
  extra x ticks={-10,10},
  extra x tick labels={-10,10},
  extra y ticks={-10,10},
  extra y tick labels={-10,10},
  tick style={very thick},
  legend style={
  at={(rel axis cs:0,1)},
  anchor=north west,draw=none,inner sep=0pt,fill=gray!10}
]
\addplot[domain=-10:10,blue,thick,samples=1000,->] {sqrt (x+4)};
%%\addplot[holdot] coordinates{(0,0)(4,4)(6,-5)};
\addplot[soldot] coordinates{(0,2)(5,3)};
%%\addlegendentry{$y=x^2$}
%%\addplot[domain=0:4,blue,] {x*x};
%%\addplot[domain=4:6,blue,] {x};
%%\addplot[domain=6:10,blue] {-5};
\end{axis}
\end{tikzpicture}

答案1

您可以使用

  xticklabels={},      %% no x tick labels
  yticklabels={},      %% no y tick labels
  extra x ticks={-10,10},
  extra x tick labels={-10,10},
  extra y ticks={-10,10},
  extra y tick labels={-10,10},

代码：

\documentclass{article}
\usepackage{pgfplots}
\begin{document}
  \begin{tikzpicture}
\begin{axis}[
  axis lines=middle,
  grid=major,
  xmin=-10,
  xmax=10,
  ymin=-10,
  ymax=10,
  xlabel=$x$,
  ylabel=$y$,
  xtick={-10,...,10},
  xticklabels={},    %% no x tick labels
  ytick={-10,...,10},
  yticklabels={},    %% no y tick labels
  extra x ticks={-10,10},
  extra x tick labels={-10,10},
  extra y ticks={-10,10},
  extra y tick labels={-10,10},
  tick style={very thick},
  legend style={
  at={(rel axis cs:0,1)},
  anchor=north west,draw=none,inner sep=0pt,fill=gray!10}
]
\addplot[domain=-3:3,blue,thick,samples=100,<->] {x^2};
\addplot coordinates{(0,0)(4,4)(6,-5)};
\addplot coordinates{(4,16)(6,6)(10,-5)};
%%\addlegendentry{$y=x^2$}
%%\addplot[domain=0:4,blue,] {x*x};
\addplot[domain=4:6,blue,] {x};
\addplot[domain=6:10,blue] {-5};
\end{axis}
\end{tikzpicture}
\end{document}

在此处输入图片描述

xlabel style ={at={(1,0.5)},above right},
ylabel style ={at={(0.5,1)},above right},

在轴选项中获取

在此处输入图片描述

对于编辑的问题，您必须指定xlabel和ylabel。

  xlabel=$x$,
  ylabel=$y$,
  xlabel style ={at={(1,0.5)},above right},
  ylabel style ={at={(0.5,1)},above right},
