如何使坐标值加粗？

Question

我正在尝试在条形图中将这个值 (16.49) 加粗。我似乎找不到任何答案。

\begin{figure}[ht]
\label{fig:table}
\begin{tikzpicture}

\begin{axis}[
%axis line style={draw=none}, 
major grid style={dotted,black},
width=0.33\textwidth,
height=0.33\textwidth,
xbar, xmin=0, xmax=70,
yticklabel style={align=center},
xlabel={DEF \%},
xlabel style={font=\smaller},
symbolic y coords={%
                    {a},
                    {b},
                    {c},
                    {d},
                    {e},
                    {f},
                    {g},
                    {g},
                    {i},               
                    {j}
                    },
ytick=data,
nodes near coords={\pgfmathprintnumber[zerofill, fixed, precision=1]{\pgfplotspointmeta}},
every node near coord/.append style={font=\smaller},
nodes near coords align={horizontal},
ytick=data,
]
\addplot [fill=gray!90,draw=black!70] 
coordinates {(16.49,{a})
            (17.60,{b})
            (26.37,{c})
            (29.0,{d})
            (29.83,{e})
            (29.99,{f})
            (36.22,{g})
            (43.80,{h})
            (49.55,{i})
            (54.50,{j})       
            };
\end{axis}
\end{tikzpicture}

您可以使用 来coordinate style/.condition格式化单个值，使其不同于其他值。我对您的原始代码进行了一些调整：

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

\begin{document}

\begin{tikzpicture}
\begin{axis}[
    width=0.5\textwidth,
    height=0.5\textwidth,
    xbar, xmin=0, xmax=70,
    yticklabel style={align=center},
    xlabel={Log-Average Miss Rate \%},
    xlabel style={font=\smaller},
    symbolic y coords={%
        {a},
        {b},
        {c},
        {d},
        {e},
        {f},
        {g},
        {h},
        {i},               
        {j}
    },
    ytick=data,
    nodes near coords={
        \pgfmathprintnumber[zerofill, fixed, precision=1]{\pgfplotspointmeta}
    },
    coordinate style/.condition={x == 16.49}{font=\smaller\boldmath},
    coordinate style/.condition={x != 16.49}{font=\smaller},
]
\addplot [fill=gray!90,draw=black!70] 
    coordinates {
        (16.49,{a})
        (17.60,{b})
        (26.37,{c})
        (29.0,{d})
        (29.83,{e})
        (29.99,{f})
        (36.22,{g})
        (43.80,{h})
        (49.55,{i})
        (54.50,{j})       
    };
\end{axis}
\end{tikzpicture}

\end{document}

使相关刻度变为粗体的一个简单解决方案是明确定义刻度标签：

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

\begin{document}

\begin{tikzpicture}
\begin{axis}[
    width=0.5\textwidth,
    height=0.5\textwidth,
    xbar, xmin=0, xmax=70,
    yticklabel style={align=center},
    xlabel={Log-Average Miss Rate \%},
    xlabel style={font=\smaller},
    symbolic y coords={%
        {a},
        {b},
        {c},
        {d},
        {e},
        {f},
        {g},
        {h},
        {i},               
        {j}
    },
    ytick=data,
    yticklabels={\textbf{a},b,c,d,e,f,g,h,i,j},
    nodes near coords={
        \pgfmathprintnumber[zerofill, fixed, precision=1]{\pgfplotspointmeta}
    },
    coordinate style/.condition={x == 16.49}{font=\smaller\boldmath},
    coordinate style/.condition={x != 16.49}{font=\smaller},
]
\addplot [fill=gray!90,draw=black!70] 
    coordinates {
        (16.49,{a})
        (17.60,{b})
        (26.37,{c})
        (29.0,{d})
        (29.83,{e})
        (29.99,{f})
        (36.22,{g})
        (43.80,{h})
        (49.55,{i})
        (54.50,{j})       
    };
\end{axis}
\end{tikzpicture}

\end{document}
