Insert space between tick labels and axis in Pgfplots

One solution is to specify a xticklabel style in order to shift it with yshift=-2pt, i.e.:

...
\subfloat[Linear horizontal axis]{
    \begin{tikzpicture}
    \begin{axis}[
ytick pos=right, width=5cm, height=5cm,
xticklabel style={yshift=-2pt},% <--- add in second subfigure
                ]
    \addplot
    table[row sep=crcr]{%
    1    1\\
    10   2\\
    };
    \end{axis}
    \end{tikzpicture}%
}%
