一张图表中不同颜色的误差线

一张图表中不同颜色的误差线

我在一张图中有两个图。每个图都有自己的误差线。我该如何根据它们的图为误差线着色（即红色和蓝色）？例如，如果我将误差线颜色设置为红色，那么即使是图片中显示的蓝色图，最终误差线也会是红色的。 在此处输入图片描述

这是我使用的代码

\documentclass{standalone}

    every minor tick/.append style={black,line width=0.6pt},
    every x tick label/.append style={black},
    every y tick label/.append style={black}
}

\pgfdeclareplotmark{fat-}
{%
    \pgfsetlinewidth{0.4}
    \pgfpathmoveto{\pgfqpoint{\pgfplotmarksize}{0pt}}%
    \pgfpathlineto{\pgfqpoint{-\pgfplotmarksize}{0pt}}%

}%

答案1

error bars/error bar style={blue}您可以通过添加选项将误差线颜色更改为蓝色\addplot。也就是说，对于包含蓝色数据点的绘图，您应该有

\addplot [
  only marks,mark=*,
  mark options={scale=0.7,blue,fill=white},
  error bars/error bar style={blue} % ⟵ this was the line I added
] table [x=x,y=y,y error=ey] {...}

包含红色数据点和蓝色数据点的图。所有红色数据点都有红色误差线，所有蓝色数据点都有蓝色误差线。

另外，仅供参考，如果您加载 PGFPlots，则不需要\usepackage{tikz}。毕竟，您制作的每个图都被包围\begin{tikzpicture} ... \end{tikzpicture}，这表明 Ti钾Z 可以正常工作，无需明确加载包:)
