如何删除 y 轴上的刻度指示器

Question

我想绘制一些 y 坐标较小的数据。我使用以下代码进行编译，结果在 y 轴上出现了一个意外的 $10^{-2}$（见下图）。有办法去掉它吗？谢谢！

\documentclass[11pt]{article}
\usepackage{tikz}
\usepackage{graphicx}
\usepackage{pgfplots}

\begin{document}
\begin{tikzpicture}[scale=0.8]
\begin{axis}[
axis lines = left,
xlabel={$\theta$},
    ylabel={},
    axis line style = thick,
    xmin=-1, xmax=2.1,
    ymin=-0.015, ymax=0.025,
    ytick={}, yticklabels={}, 
    xtick={0,1}, xticklabels={$0$, $1$}, xtick style={draw=none}, ytick style={draw=none},
    legend style={at={(1.1,1)}},
    legend style={draw=none},
    ymajorgrids=false,
    grid style=dashed,
    every axis x label/.style={
    at={(ticklabel* cs:1.0)},
    anchor=west,},
    every axis y label/.style={
    at={(ticklabel* cs:1)},
    anchor=south,
},
]
\end{axis}
\end{tikzpicture}
\end{document}

Answer 1

您可以使用scaled ticks=false以下选项关闭常见的缩放因子：

\documentclass[11pt]{article}
\usepackage{tikz}
\usepackage{graphicx}
\usepackage{pgfplots}

\begin{document}
\begin{tikzpicture}[scale=0.8]
\begin{axis}[
axis lines = left,
xlabel={$\theta$},
    ylabel={},
     scaled ticks=false,
    axis line style = thick,
    xmin=-1, xmax=2.1,
    ymin=-0.015, ymax=0.025,
    ytick={}, yticklabels={}, 
    xtick={0,1}, xticklabels={$0$, $1$}, xtick style={draw=none}, ytick style={draw=none},
    legend style={at={(1.1,1)}},
    legend style={draw=none},
    ymajorgrids=false,
    grid style=dashed,
    every axis x label/.style={
    at={(ticklabel* cs:1.0)},
    anchor=west,},
    every axis y label/.style={
    at={(ticklabel* cs:1)},
    anchor=south,
},
]
\end{axis}
\end{tikzpicture}
\end{document}

解决您的问题的（真正的）MWE（最小工作示例）的一个例子：

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

\begin{document}
    \begin{tikzpicture}
\begin{axis}[
    axis lines = left,
    axis line style = thick,
    xlabel={$\theta$}, 
    xlabel style={at={(1,0)},anchor=west},
    xmin=-1,        xmax=2.1,
    ymin=-0.015,    ymax=0.025,
    xtick={0,1}, 
    tick style={draw=none}, 
    ytick=\empty,
%    extra y ticks = {0.005,0.01},   % if needed some thicks
    legend style={at={(1.1,1)}, draw=none},
]
\end{axis}
    \end{tikzpicture}
\end{document}

Answer 3

答案是，ytick=\empty, 这会使 tikz 在 y 轴刻度上不放置任何内容。
