As a followup question to my answer here, I have a problem with the polaraxis of pgfplots. When I try to define xtick, nothing changes compared to dropping the option.
MWE
\documentclass{standalone}
\usepackage{pgfplots}
\usepgfplotslibrary{polar}
\pgfplotsset{compat=1.13}
\begin{document}
\begin{tikzpicture}
\begin{polaraxis}[xtick={0,45,...,360},]
\end{polaraxis}
\end{tikzpicture}
\end{document}
