PGFPlots：具有“线性”标签的对数刻度

Question

我创建了一个带有对数 x 轴的条形图。问题是：条形的标签也是对数的，例如1.3代替20。

我怎样才能获得真实的数字作为标签？

提前致谢。

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

\begin{document}
\begin{tikzpicture}
    \begin{axis}
        [
            xbar,
            xbar=0pt,
            enlargelimits=0.15,
            width=.9\textwidth,
            label style={font=\footnotesize},
            ytick={0,...,9},
            yticklabels = {val1, val2, val3, val4, val5, val6, val7, val8, val9, val10},
            ytick=data,
            enlarge y limits={abs=1.125},
            nodes near coords,
            every axis plot/.append style={fill},
            y = 1.2cm,
            xmode=log,log basis x=10
        ]
        \addplot coordinates {(168000, 0) (832, 1) (2696, 2) (131162, 3) (31492, 4) (6, 5) (2858, 6) (152196, 7) (698264, 8) (1100, 9)};
        \addplot coordinates {(2487066, 0) (34174, 1) (44184, 2) (409040, 3) (68204, 4) (35200, 5) (35528, 6) (656328, 7) (702332, 8) (38348, 9)};
        \addplot coordinates {(188540, 0) (1268, 1) (1848, 2) (159124, 3) (32788, 4) (836, 5) (2888, 6) (146236, 7) (499024, 8) (2696, 9)};
    \end{axis}
\end{tikzpicture}
\end{document}

结果：

Answer 1

point meta=rawx这可以通过添加选项来实现axis。

因为这似乎“混淆”了默认值，所以您也nodes near coords align=auto需要设置该值。horizontal
