我想使用以下命令增加图表中误差线的粗细。
\pgfplotsset{/pgfplots/error bars/error bar style={ultra thick,black}}
但是，正如您在图片中看到的，它不会改变误差线帽的宽度。
有谁知道如何解决这一问题？
我曾经\newcommand{\myfont}{\fontfamily{cmss}\fontseries{ul}\selectfont}让文本字体变浅，但不知何故也没有效果。例如，看看 [J/m^2] 单位。有人可以对此发表评论吗？
这是我使用的完整代码

答案1
在这个答案中，我只提到了误差线的粗细，我对字体粗细没什么可说的。简短的回答是，将pgfplots绘图标记堆叠在末尾，并且这些标记的宽度不受您选择的线宽的影响。（较长的答案，我不会详细说明，会告诉您嵌套pgfplotss tikzpicture，这从手册 v1.16 第 318 页顶部的代码中可以看出。在我看来，这种嵌套的结果很难控制。）因此，您需要做的就是定义一个更粗的绘图标记
\pgfdeclareplotmark{fat-}
{%
\pgfsetlinewidth{2pt}
\pgfpathmoveto{\pgfqpoint{\pgfplotmarksize}{0pt}}%
\pgfpathlineto{\pgfqpoint{-\pgfplotmarksize}{0pt}}%
\pgfusepathqstroke
}%
宽度2pt可能应该降低，然后将其插入。
