删除两个轴上的垂直线和水平线（tikzpicture）

Question

我有下图：

我希望能够删除轴上的所有条纹或线条，我用黑色将其括起来。这是我的代码，非常感谢您的帮助。

\documentclass{article}
\usepackage{pgfplots}
\pgfplotsset{compat=1.18}

\usepackage[margin = 0.9in]{geometry}
\usepackage{graphicx}
\usepackage{float}

\begin{document}

\begin{figure}[H]
    \centering
    \begin{tikzpicture}
        \begin{axis}[
            height=5.5cm, width=0.8*\textwidth,
            axis lines=middle,
            %grid, grid style = {dashed},
            xlabel=$s$, xlabel style={anchor=west},
            ylabel style={anchor=south},
            xmin=-4, xmax=4,
            ymin=-3,  ymax=3,
            xticklabels=none, yticklabels=none,
            ]
            \addplot [
            domain=-3.8:3.8, 
            samples=100, 
            thick, smooth,
            ] {sin(deg(3*x))};
        \end{axis}
    \end{tikzpicture}
\end{figure}
\end{document}

Answer 1

像这样：

xticklabels=none, yticklabels=none,你应该写而不是xtick=\empty, ytick=\empty。因此，完整的 MWE 应该是：

\documentclass{article}
\usepackage{pgfplots}
\pgfplotsset{compat=1.18}

\usepackage[margin = 0.9in]{geometry}
\usepackage{graphicx}
\usepackage{float}

\begin{document}

\begin{figure}[H]
    \centering
    \begin{tikzpicture}
        \begin{axis}[
            height=5.5cm, width=0.8*\textwidth,
            axis lines=middle,
            xlabel=$s$, xlabel style={anchor=west},
            ylabel style={anchor=south},
            xmin=-4,    xmax=4,
            ymin=-2,    ymax=2,
            xtick=\empty, ytick=\empty  % <---
            ]
            \addplot [
            domain=-3.8:3.8,
            samples=100,
            thick, smooth,
            ] {sin(deg(3*x))};
        \end{axis}
    \end{tikzpicture}
\end{figure}
\end{document}

Answer 2

只需添加ticks=none到您的代码中：

\documentclass{article}
\usepackage{pgfplots}
\pgfplotsset{compat=1.18}

\usepackage[margin = 0.9in]{geometry}
\usepackage{graphicx}
\usepackage{float}

\begin{document}

\begin{figure}[H]
    \centering
    \begin{tikzpicture}
        \begin{axis}[
            height=5.5cm, width=0.8*\textwidth,
            axis lines=middle,
            %grid, grid style = {dashed},
            xlabel=$s$, xlabel style={anchor=west},
            ylabel style={anchor=south},
            xmin=-4, xmax=4,
            ymin=-3,  ymax=3,
            xticklabels=none, yticklabels=none,
            ticks=none
            ]
            \addplot [
            domain=-3.8:3.8, 
            samples=100, 
            thick, smooth,
            ] {sin(deg(3*x))};
        \end{axis}
    \end{tikzpicture}
\end{figure}
\end{document}
