如何删除给定图表中的一个“0”（原始标签）？

Question

我想知道是否有人能帮我移除原点标签并将“0”精确地放在角落位置。根据我的理解，我们似乎应该移除这些标签并添加

extra x ticks={0},
extra x tick style={xticklabel style={anchor=northeast}},

但是当我这样做时，结果有 3 个原产地标签。

以下是我正在使用的代码

Answer 1

将以下内容添加到 的选项列表中axis：

xtick={1,...,8},                                % explicitly sets ticks 1 to 8 for x-axis
ytick={50,100,...,300},                         % explicitly sets ticks 50 to 300 for y-axis
extra x ticks={0},                                           % sets one extra tick at 0
extra x tick style={xticklabel style={anchor=north east}},   % aligns extra tick

最后，你的代码应该是这样的：

\documentclass[12pt]{article}
\usepackage[paperwidth=5in, paperheight=3.6in]{geometry}
\geometry{left=2mm, right=2mm, top=4mm, bottom=2mm}

\usepackage{pgfplots}
\pgfplotsset{compat=newest}
\usepgfplotslibrary{fillbetween}

\begin{document}
\begin{figure}[!t]
\centering
\begin{tikzpicture}[
        declare function={a(\x)=50*\x;},
    ]
    \begin{axis}[
        axis y line=left,
        axis x line=bottom,
        grid=major,
        ylabel = $\textbf{Words typed}$,
        xlabel = $\textbf{Time in minutes}$,
        width=4.7in, height=3.3in,
        ymin=0, ymax=325,
        xmin=0, xmax=8.5,
        axis line style = thick,
        major tick style = thick,
        xtick distance = 1,
        x grid style={thin, opacity=0.5},
        ytick distance = 50,
        y grid style={thin, opacity=0.5},
        axis on top=false,
        xtick={1,...,8},
        ytick={50,100,...,300}, 
        extra x ticks={0},
        extra x tick style={xticklabel style={anchor=north east}}
    ]

%FUNCTION
\addplot[name path=a, ultra thick, -latex, samples=300, smooth, domain=0:6.5, red] {a(x)}  node [pos=0.9, left, red, font=\small] {};

\end{axis}
\end{tikzpicture}
\end{figure}
\end{document}

我强烈建议您清理您的代码并删除不需要的包，并且不要加载两次包。

要删除刻度标记，您可以使用：

extra x tick style={xticklabel style={anchor=north east}, major tick length=0pt}
