在一个轴上具有固定数字格式的对数图

Question

我怎样才能以对数形式表示 x 轴和 y 轴，但仅在 x 轴上使用“正常”数字格式？

我尝试了一些东西，如工作示例中所示：

\documentclass{scrartcl}

\usepackage{pgfplots}
\pgfplotsset{compat=1.16}

\begin{document}

\begin{tikzpicture}
  \begin{axis}[
    xmode=log,
     % still in logarithmic:
    xtick={1, 25, 50, 100},
    % obtuse and produces rounding errors in real examples, e.g, 63.99:
    % xticklabel={\pgfmathfloatparsenumber{\tick}\pgfmathfloatexp{\pgfmathresult}\pgfmathprintnumber{\pgfmathresult}},
    % changes both axes:
    % x tick label style={log ticks with fixed point},
    ymode=log,
    domain=1:100
    ]
    \addplot+ {ln(x)};
  \end{axis}
\end{tikzpicture}

\end{document}

谢谢！

像这样吗？

\documentclass{scrartcl}

\usepackage{pgfplots}
\pgfplotsset{compat=1.16}

\begin{document}

\begin{tikzpicture}
  \begin{axis}[
    xmode=log,
     % still in logarithmic:
    xtick={1, 25, 50, 100},
    % obtuse and produces rounding errors in real examples, e.g, 63.99:
    % xticklabel={\pgfmathfloatparsenumber{\tick}\pgfmathfloatexp{\pgfmathresult}\pgfmathprintnumber{\pgfmathresult}},
    % changes both axes:
    % x tick label style={log ticks with fixed point},
    ymode=log,
    xticklabel={\pgfmathparse{exp(\tick)}\pgfmathprintnumber{\pgfmathresult}},
    domain=1:100
    ]
    \addplot+ {ln(x)};
  \end{axis}
\end{tikzpicture}

\end{document}
