Minor ticks lost in log-log plot if replacing major tick with a symbol

Question

I'm trying to create a simple log-log plot with the following code:

\documentclass[border=5pt]{standalone}
\usepackage{pgfplots}        
\usetikzlibrary{calc}

\begin{document}

\begin{tikzpicture}[]         
    \begin{loglogaxis}[
        log basis x=10,
        log base 10 number format code/.code={$-10^{\pgfmathprintnumber{#1}}$},
        y dir=reverse,
        xmin=1e2, xmax=1e4,
%        xtick={1e2,1e3,1e4},
%        xticklabels={$10^2$, $10^3$, $n$},
        ]

\addplot [] table[x index=0,  y expr=-\thisrowno{1}, row sep=crcr]{%
260      -0.556631 \\
4110        -10.0369 \\
};

\addplot [] table[x index=0,  y expr=-\thisrowno{1}, row sep=crcr]{%
242    -1.76855 \\
3642        -11.456032992458257 \\
};

   \end{loglogaxis}
\end{tikzpicture}    
\end{document}

which produces the expected result:

The problem is that when I try to replace the right-most tick value of 10^4 with a symbol, all minor ticks disappear. I could use xlabel for this, but I would like to try this approach for consistency with other figures. Is there an alternative way to replace that right-most value with the symbol n?

Answer 1

The solution to my problem was finally to only use xticklabels={$10^2$, $10^3$, $n_d$}. For some reason, adding xtick interferes with the minor ticks in a log-log plot.
