tikz 图中乘数标题的位置

我正在尝试创建一个具有两个独立 y 轴的图。右侧 y 轴为单位 * 10^5。但是，乘法标题的位置不正确。我使用以下代码：

\begin{tikzpicture}
  \begin{axis}[
    axis y line* = left,
    xlabel = grid size $l$,
    ylabel = \textcolor{blue}{\footnotesize$\blacksquare$}
indices per $\mathcal{T}$,
    ymode = log,
    log origin=infty]
    \addplot[color=blue,mark=x] coordinates {
          (15000,317.631)
          (20000,182.318)
          (40000,49.3089)
          (80000,14.4933)
          (160000,5.02436)
          (320000,2.37795)
          (500000,1.81145)
          (640000,1.62701)
          (1280000,1.29392)
          (2560000,1.18447)
      };
  \end{axis}

  \begin{axis}[
        hide x axis,
        ylabel near ticks,
        axis y line*=right,
        ylabel={\textcolor{red}{\footnotesize$\blacksquare$}  number of $\mathcal{T}_{pot}$}]
            \addplot[color=red,mark=x] coordinates {
          (15000,40819)
          (20000,41179)
          (40000,41179)
          (80000,42720)
          (160000,44312)
          (320000,44866)
          (640000,98610)
          (1280000,168980)
          (2560000,184202)
      };
      \draw[black,dashed] (axis cs:500000,0) -- (axis cs:500000,200000);
      \draw (axis cs:500000,200000) node[below right] {$l_r$};
  \end{axis}
\end{tikzpicture}

其结果如下：

在此处输入图片描述

但是，我希望右上角的 *10^5 与 y 轴右侧对齐，而不是左侧。它应该像右侧 y 轴的刻度标签一样对齐。

非常感谢您的帮助！

答案1

您需要调整的选项是y tick scale label style。如果您指定为

at={(yticklabel cs:1.05)}

这将与 y 轴上的其他刻度对齐，超出末尾 5%。如果您指定

at={(yticklabel cs:1.05,10pt)}

10pt那么它将被进一步向右移动。
