# how to remove pgfplots circular points

In the graph below, there are large circular point marks. Is there a way of removing them?

My graph code is

\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,
}]

This question came from our site for professional and enthusiast programmers.

With pgfplots you can use:

• mark=none to disable the marks
• mark=* to specify the marker to use
• only marks to show only the points

## Code:

\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}
