PGFPlots 讓小對數值變得可呈現

我的數據確實不清晰可見，如： no error shakers can be see 50x150-k1fornor 50x150-k1。 （顯然）這是因為與 相比，這些值非常小40x150-k。我以為我可以將 x 軸設為對數（如下例所示），但這並沒有太大幫助。我預期誤差線50x150-k2(明顯) 幾乎與 一樣大16x75-s，因為它們具有相似的 kdelta 值。

根據表，晶須由 k-1 和 k+1 給出，kdelta 為 k+1 / k-1。

例子

我生成圖像中的圖形的程式碼如下所示：

\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}

什麼程式碼可以更好地呈現誤差範圍？我仍然期望 log10 是正確的。

請注意，我專注於要點並添加了兩個$以使程式碼編譯。人們可以進一步調整程式碼。
