如何删除 pgfplots 圆形点

Question

下图中，有大圆点标记。有办法去除它们吗？

我的图形代码是

\begin{figure}[H] 
\begin{tikzpicture} 
\begin{axis}[ 
height=9cm, 
width=12cm, 
grid=major, 
xlabel={Levels},
ylabel={Speed},
legend style={
cells={anchor=east},
legend pos=outer north east,
}]

您pgfplots可以使用：

• mark=none禁用标记
• mark=*指定要使用的标记
• only marks仅显示点

代码：

\documentclass{article}
\usepackage{pgfplots}

\begin{document}
\begin{tikzpicture} 
\begin{axis}
    \addplot [mark=none,  red,   ultra thick] coordinates { (1,6) (2,8) (3,10)}
    node [midway, sloped, above] {mark=none};

    \addplot [mark=*,     brown, ultra thick] coordinates { (1,4) (2,6) (3,8)} 
    node [midway, sloped, above] {mark=*};

    \addplot [only marks, blue,  ultra thick] coordinates { (1,2) (2,4) (3,6)}
    node [midway, sloped, below] {only marks};
\end{axis} 
\end{tikzpicture}
\end{document}
