如何修复轴上功率 (10^x) 的外观，使其接近或在 x 轴上

Question

我正在绘制一个条形图，并且 x 轴处的功率 (10^x) 距离轴很远，如下图所示：

我使用以下代码绘制该图：\pgfplotstableread{datahis.dat}\loadedtable

\begin{tikzpicture}[scale = 1]
 \begin{axis}[ybar, 
    ybar interval = 1,
    mark = none,
    draw = none,
    xtick={ 2e6,4e6, 6e6,8e6, 10e6},
    ytick={ 2e+3,4e+3,6e+3,8e+3,10e+3, 12e+3 },
    xmax =10.199969990000000000e+06,
    enlargelimits=0.05,
    grid = none, 
    ylabel = {{\small Raw Events}},
    xlabel = {{\small Time ($\mu$s)}},
    tick align=inside,
    tickpos=left,
    every axis plot post/.append style=
    {mark=none},
    legend columns=-1,
    area style,
    bar width = 0.6
    ]
    \addplot +[ybar, draw=blue,fill=black!30!white, mark = none] table[x= edges, 
    y=bins] from \loadedtable;
    \addplot[red,sharp plot,update limits=false]
    coordinates {(7.866602500000000000e+05, 200) (9.086350000000000000e+06,200)}
    node[above] at (axis cs:7.8407000000000000e+06,270) {\footnotesize{Threshold 
    rate}};
   \end{axis}
   \end{tikzpicture}

有人可以建议如何解决这个问题吗？

谢谢。

人们通常会将small选项添加到小图表的轴上，但您也可以像这样将乘数向上移动：

\documentclass[tikz, border=1cm]{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.18}
\begin{document}
\begin{tikzpicture}
\begin{axis}[
width=5cm,
xmin=0, xmax=10e6,
ymin=0, ymax=12e+3,
xtick={2e6,4e6, 6e6,8e6,10e6},
ytick={2e+3,4e+3,6e+3,8e+3,10e+3,12e+3},
xmax =10e+06,
enlargelimits=0.05,
ylabel={\small Raw Events},
xlabel={\small Time ($\mu$s)},
tick align=inside,
tickpos=left,
x tick scale label style={yshift=4pt},
]
\end{axis}
\end{tikzpicture}
\end{document}
