Tikz：轴覆盖标记

Question

我正在创建一个简单的图表，其中的图带有标记。我使用 decorations.markings 库来创建间距均匀的标记。但是，靠近图表边界的标记被轴覆盖，请参见下面的示例 - 右侧的标记接近 1。我更愿意将标记放置在轴“上方”并完全可视化它们。有什么想法可以做到这一点吗？感谢您的任何建议/提示！

\documentclass[]{minimal}    
\usepackage{tikz}
\usepackage{pgfplots}

\usetikzlibrary{calc,trees,positioning,arrows,chains,
  shapes.geometric,
  decorations.pathreplacing,
  decorations.pathmorphing,shapes,
  matrix,shapes.symbols,automata,decorations.markings}

\makeatletter
\tikzset{
  nomorepostactions/.code={\let\tikz@postactions=\pgfutil@empty},
  mymark/.style 2 args={decoration={markings,
    mark= between positions 0.05 and 1 step
     (1/11)*\pgfdecoratedpathlength with{%
     \tikzset{#2,every mark}\tikz@options
       \pgfuseplotmark{#1}%
     },  
    },
  postaction={decorate},
  /pgfplots/legend image post style={
        mark=#1,#2,every path/.append style={nomorepostactions}
},
},
}
\makeatother


\begin{document}

\begin{tikzpicture}
\begin{axis}[height=9cm, 
      width=13cm, 
      grid=major, 
      xmin=0, 
      xmax=1, 
      ymin=0, 
      ymax=1
     ] 

\addplot [color=black, 
      line width=1pt, 
      mark size=3pt, 
      mymark={*}{mark options={draw=white,fill=black}}
     ] coordinates {
              (0,   0)
              (0.99,0.5)
              (1,   1)
            };

\end{axis} 
\end{tikzpicture}

\end{document}

只需添加clip=false选项axis：
