我的数据确实不清晰可见，例如：看不到 和 的误差线50x150-k1。50x150-k1这（显然）是因为与 相比，这些值真的很小40x150-k。我以为我可以将 x 轴设为对数（如下例所示），但这并没有多大帮助。我预计 的误差线50x150-k2（明显）几乎与 一样大16x75-s，因为它们具有相似的 kdelta 值。
根据表格，晶须由 k-1 和 k+1 给出，其中 kdelta 为 k+1 / k-1。
我生成图像中的图形的代码如下：
\pgfplotstableread{data.txt}\data
\pgfplotstableset{create on use/error/.style={
create col/expr={\thisrow{uci}-\thisrow{mean}}
}
}
\begin{tikzpicture}[trim axis left,trim axis right]
\begin{axis}[y=-\baselineskip,
scale only axis,
width = 7cm,
enlarge y limits = {abs=0.5},
axis y line* = middle,
y axis line style = dashed,
ytick = \empty,
axis x line* = bottom,
xmode=log,
]
\addplot+[only marks][error bars/.cd,x dir=both, x explicit]
table [x=mean,y expr=\coordindex,x error=error]{\data};
\end{axis}
\end{tikzpicture}
什么代码可以更好地显示错误范围？我仍然希望 log10 是正确的。

请注意，我重点突出了要点，并添加了两个代码$以使代码能够编译。可以进一步调整代码。
