# Strange behaviour of pin angles with PGFPlots [duplicate]

TikZ node pin angle in 2D plot

I need to have some marks in a diagram pointing at characteristic points of the plot. To not have the text printed over the plot line I needed to adjust the angles of the pins.

The angles however don't seem to work the way they should. See the following example:

\documentclass{standalone}
\usepackage{pgfplots}
\begin{document}
\begin{tikzpicture}
\begin{axis}[ymax=2]
\node[coordinate,pin=93:{93 degrees}]
at (axis cs:-270,1) {};
\node[coordinate,pin=94:{94 degrees?}]
at (axis cs:90,1) {};
\end{axis}
\end{tikzpicture}
\end{document}


The first pin with an angle of 93 degrees looks correct, but the second one does clearly not follow the 94 degrees. An equal behaviour occurs by the way with 87 degrees being correctly set and 86 degrees fails to do so.

Why is that so? A bug in pgfplots? How can I overcome this? Is there another way to specify pins that have the angle they should have?
