PGFPLOTS 如何在不增加标记边框宽度的情况下增加线宽

Question

如何增加线宽，同时保持标记边框宽度不变？

Answer 1

它的目的是mark options控制标记的参数。因此，mark options={line width=0.4pt}您可以通过拨号将线宽设置为其标准值。

\usepackage{pgfplots}
\pgfplotsset{compat=1.17}
\begin{document}

\begin{tikzpicture}
\begin{axis}[
            axis lines = left,
            enlarge x limits=0.1,
            enlarge y limits=0.1,
            ]
        \addplot [
            mark=*,
            color=blue,
            scatter,
            scatter/use mapped color={draw=black},
            error bars/.cd,
            y dir = both, 
            y explicit,
            error bar style={color=black},
            ] table [x index=0, y index=1, y error index=2]{
            0 2 0.1
            2 0 0.1
            };
        \addplot [line width=2pt,mark options={line width=0.4pt},
            mark=*,
            color=red,
            scatter,
            scatter/use mapped color={draw=black},
