Cómo deshacerse de pequeñas marcas en la parte superior de pgfplots

Question

Estoy buscando una manera de deshacerme de las pequeñas garrapatas en la parte superior de mi figura (las pequeñas grises), pero ¿mantenerlas intactas a lo largo del eje x? Mi código es el siguiente:

\begin{figure}[h]
\caption{Distribution of visitor}
\label{DistributionFirmVisitors}
\begin{center}
\begin{tikzpicture}
\begin{axis}[width=10cm,height=7cm,
ylabel={\% of EDGAR visitors},
xmin=1, 
xmax=200,
ymin=0.3, 
ymax=1,
xtick={1, 25, 50, 75, 100, 125, 150, 175, 200},
ytick={0.3,0.4,0.5,0.6,0.7,0.8,0.9,1},
xticklabel style={/pgf/number format/1000 sep=,rotate=60,anchor=east,font=\normalsize},
tick label style={/pgf/number
format/precision=5},
scaled y ticks = false,
legend pos=north east,
ymajorgrids=true,
grid style=dashed,
every axis plot/.append style={thick},
axis background/.style={fill=gray!5},
] 

\addplot[
color=black,
]
coordinates {

(1, 0.1)
(25, 0.1)
(50,0.1)
(75,0.1)    
(100,   0.1)
(200,   0.1)

};


\end{axis}
\end{tikzpicture} \\
\end{center}
\end{figure} \vspace{0.4cm}

Supongo que estás buscando xtick pos=lower.

% used PGFPlots v1.16
\documentclass[border=5pt]{standalone}
\usepackage{pgfplots}
    \pgfplotsset{compat=1.3}
\begin{document}
\begin{tikzpicture}
    \begin{axis}[
        width=10cm,
        height=7cm,
        ylabel={\% of EDGAR visitors},
        xmin=1,
        xmax=200,
        ymin=0.3,
        ymax=1,
        xtick={1, 25, 50, 75, 100, 125, 150, 175, 200},
        ytick={0.3,0.4,0.5,0.6,0.7,0.8,0.9,1},
        xticklabel style={
            rotate=60,
            anchor=east,
            font=\normalsize,
        },
        ymajorgrids=true,
        grid style=dashed,
        axis background/.style={fill=gray!5},
        xtick pos=lower,    % <-- added
    ]

        % (because of y = 0.1 and `ymin=0.3` it is invisible anyway)
        \addplot coordinates {(1,0.1)};

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