我正在尝试将axis y line这些问题中的位置从 0 更改为 100（1，2）。假设误差线代表百分比尺度的置信区间，因此 100% 没有区别。如果我只更改 的值，就会得到以下结果data.txt：
如您所见，虚线位于 0 处，绘制在图的左侧。代码如下：

如果我按照 Jake 的回答中的解决方案这个问题，我得到下表：
因此，空行似乎在某种程度上混淆了 pgfplots。但是，我想保留空行。我觉得我离解决方案很近了，但不知道该怎么做。有人能帮帮我吗？

答案1
毕竟这只是一条线，自己画吧：
\draw[dashed](axis cs:100,0)--(axis cs:100,100);
假设“官方”轴线已被移除：
axis y line=none,

答案2
您可以调整axis line origin样式以仅适用于非空条目：
\pgfplotsset{
axis line origin/.style args={#1,#2}{
x filter/.code={
\ifx\pgfmathresult\empty\else\pgfmathparse{\pgfmathresult-#1}\fi
},
y filter/.code={
\ifx\pgfmathresult\empty\else\pgfmathparse{\pgfmathresult-#2}\fi
},
xticklabel=\pgfmathparse{\tick+#1}\pgfmathprintnumber{\pgfmathresult},
yticklabel=\pgfmathparse{\tick+#2}\pgfmathprintnumber{\pgfmathresult}
}
