如何在 PGFPlots 中完全自定义箭头？

Question

tikz我讨厌或中的预定义箭头样式pgfplots，并设法tikz通过使用装饰在中应用自定义箭头。现在我尝试在中应用相同的装饰代码，pgfplots axis但失败并出现神秘错误。

我找到了这个答案：https://tex.stackexchange.com/a/51584/75284具体来说是将装饰应用于pgfplots轴线，它可以为我编译，但是插入\fill我需要的箭头命令并删除该\arrow命令时，编译就会挂起：

\documentclass[border=5mm]{standalone}
\usepackage{pgfplots}
\usetikzlibrary{arrows, decorations,decorations.markings}

\tikzset{ % this is the arrow style I want
    myarrow/.style={decoration={markings, mark=at position 1 with {
    \fill(-0.3,-0.05) -- (0,0) -- (-0.3,0.05) -- cycle;
    }}, postaction={decorate},shorten >=5 pt}
}


\makeatletter
\tikzset{
    nomorepostaction/.code=\makeatletter\let\tikz@postactions\pgfutil@empty, % From https://tex.stackexchange.com/questions/3184/applying-a-postaction-to-every-path-in-tikz/5354#5354
    my axis/.style={
        postaction={
            decoration={
                markings,
                mark=at position 1 with {
                \arrow[ultra thick]{latex} % this works
                %\fill(-0.3,-0.05) -- (0,0) -- (-0.3,0.05) -- cycle; % this is just the \fill command pasted in
                }
            },
            decorate,
            nomorepostaction
        },
        thin,
        -, % switch off other arrow tips
        every path/.append style=my axis % this is necessary so it works both with "axis lines=left" and "axis lines=middle"
    }
}
\makeatother

\begin{document}
\begin{tikzpicture}

\begin{axis}[
    axis lines=middle,
    axis line style={my axis}
]
\addplot coordinates {(-0.1,-0.2) (1.2,1.2)};
\end{axis}
\draw[myarrow] (0,0) -- (3,5);
\end{tikzpicture}
\end{document}

不过，这只是我的尝试。我欢迎任何关于如何在pgfplots轴线中使用完全可自定义的箭头的解决方案。例如，如果有办法将\draw命令箭头线放置在正确的位置，它也会起作用。

我用 解决了我的问题arrows.meta，过去几年我不知何故完全错过了这个问题。

\documentclass[border=5mm]{standalone}
\usepackage{pgfplots}
\usetikzlibrary{arrows.meta}

\tikzset{
    myarrow/.style={-{Triangle[length=3mm,width=1mm]}}
}


\begin{document}
\begin{tikzpicture}

\begin{axis}[
    axis lines=middle,
    axis line style={myarrow}
]
\addplot coordinates {(-0.1,-0.2) (1.2,1.2)};
\end{axis}
\draw[myarrow] (0,0) -- (1,5.5);
\end{tikzpicture}
\end{document}
