pgfplots 中的默认 tikz 箭头样式

Question

我正在尝试将中使用的轴箭头样式更改为使用pgfplots中获得的默认样式，即tikz->

我做了一些研究，但似乎找不到方法。

Answer 1

使用axis line style={->}。

\documentclass{article}
\usepackage{pgfplots}
\pgfplotsset{compat=1.12}

\begin{document}
  \begin{tikzpicture}
    \begin{axis}[axis lines=left,axis line style={->}]

    \end{axis}
  \end{tikzpicture}
\end{document}

随着OP新添加的代码：

\documentclass{scrartcl}
\usepackage{tikz}
\usetikzlibrary{patterns}
\usepackage{pgfplots}
\pgfplotsset{compat=1.12}
\usepgfplotslibrary{fillbetween}
\begin{document}
\begin{tikzpicture}
  \begin{axis}[thick, smooth, no markers,
    xmin = -1.1, xmax = 1.1,
    ymin = -1.1, ymax = 1.1,
    axis lines = center,
    axis line style={->},              %% put here
    xlabel = $\rho_{S}$,
    ylabel = $\rho_{\tau}$
    ]
    \addplot+[name path = OBEN, samples = 1000, black, domain = -1:1]
    {min(1, 0.5+1.5*x)};
    \addplot+[name path = UNTEN, samples = 1200, black, domain= -1:1]
    {max(-1, -0.5+1.5*x)};
    \addplot[pattern = north west lines] fill between[of=OBEN and UNTEN];
  \end{axis}
\end{tikzpicture}
\end{document}
