相信我，我一直在尽一切努力去理解 pgfplots 中的误差线。
我想要做的是增加误差线的厚度/大小，以便它们在图表上更清晰。
这似乎增加了条的厚度：
\pgfplotsset{/pgfplots/error bars/error bar style={very thick}}
我没有得到任何进一步的信息。

错误标记受键 的影响/error bars/error mark options。使用此键会重置初始选项，即rotate=90，因此您还必须将其包括在内：
\documentclass{article}
\usepackage{pgfplots}
\begin{document}
\begin{tikzpicture}
\begin{axis}
\addplot+[only marks,
error bars/.cd,
y dir=both,
y explicit,
error bar style={line width=2pt},
error mark options={
rotate=90,
red,
mark size=8pt,
line width=2pt
}
]
coordinates {
(0,1) +- (0,0.35665)
(1,1.5) +- (0,-0.35048)
(2,0) +- (0,0.150255)
};
\end{axis}
