Pgfplots 条形图

Question

我试图在水平条形图上显示数字数据，但是当我尝试在 y 轴上添加字符串标签而不是数字时，它不起作用 - 我做错了什么？

代码

\documentclass{minimal}
\usepackage{pgfplots}

\begin{document}

        \begin{tikzpicture}
            \tikzstyle{every node}=[font=\large]
            \begin{axis} [xbar = .05cm,
                    bar width = 12pt,
                    xmin = 0, 
                    xmax = 4, 
                    enlarge y limits = {abs = .8},
                    enlarge x limits = {value = .25, upper},
                    title={Execution time log scale}{\large},
                    xlabel = {time[ms]},
                    ]
                \addplot coordinates {(3.66,0) (3.66,1) (3.66,2) (2.55,3)};
                \addplot coordinates {(1.35,0) (1.51,1) (1.37,2) (1.35,3)};
                 \legend{reference,author}
            \end{axis}
             
        \end{tikzpicture}
\end{document}

现在我尝试修改代码以使用符号名称

\documentclass{minimal}
\usepackage{pgfplots}

\begin{document}
            \tikzstyle{every node}=[font=\large]
            \begin{axis} [xbar = .05cm,
                    bar width = 12pt,
                    xmin = 0, 
                    xmax = 4, 
                    enlarge y limits = {abs = .8},
                    enlarge x limits = {value = .25, upper},
                    title={Execution time log scale}{\large},
                    xlabel = {time[ms]},
                    ymbolic y coords = {HD vs Monai,robust HD,mean HD,HD vs Oliviera}
                    ]
                \addplot coordinates {(3.66,HD vs Monai),(3.66,robust HD) (3.66,mean HD) (2.55,HD vs Oliviera)};
                \addplot coordinates {(1.35,HD vs Monai) (1.51,robust HD) (1.37,mean HD) (1.35,HD vs Oliviera)};
                 \legend{reference,author}
            \end{axis}
             
        \end{tikzpicture}
\end{document}

这就是我得到的

Answer 1

有一个拼写错误，ymbolic y coords应该是symbolic y coords。你这里多了一个逗号，(3.66,HD vs Monai),(3.66,robust HD)应该是(3.66,HD vs Monai) (3.66,robust HD)。而且你不能使用enlarge y limits = {abs = .8}符号 y 坐标。你必须给数字一个单位。例如enlarge y limits = {abs = .8cm}

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

\begin{document}
\begin{tikzpicture}
\tikzstyle{every node}=[font=\large]
\begin{axis} [xbar,
    bar width = 12pt,
    xmin = 0, 
    xmax = 4, 
    enlarge y limits={abs=0.8cm},
    enlarge x limits = {value = .25, upper},
    title={Execution time log scale}{\large},
    xlabel = {time[ms]},
    symbolic y coords = {HD vs Monai,robust HD,mean HD,HD vs Oliviera},
    ]
    \addplot coordinates{
    (3.66,HD vs Monai) (3.66,robust HD) (3.66,mean HD) (2.55,HD vs Oliviera)};
    \addplot coordinates{
    (1.35,HD vs Monai) (1.51,robust HD) (1.37,mean HD) (1.35,HD vs Oliviera)};
    \legend{reference,author}
\end{axis}
             
\end{tikzpicture}

\end{document}
