I have two questions:

How can I place the node midway,above the arc?
in the arc the end of the arrow is black instead of orange, how can I set the color of the spike?

This is the latex code.

\begin{tikzpicture}[auto, node distance=3cm,>=latex', scale=0.4 ,every
node/.style={transform shape}]
    % Draw axes
    \draw[->] (xyz cs:x=-5) -- (xyz cs:x=5) node[above] {$y$};
    \draw[->] (xyz cs:y=-5) -- (xyz cs:y=5) node[right] {$x$};
    \foreach \a in {20, 140, 250}
        \draw[draw=blue] (0, 0) -- (\a:4.5);

    \draw[draw=orange,->] (0,1) arc (90:20:1cm) node[midway,above]{$\theta$}; 
\end{tikzpicture}

This works as-is with PGF 3.0, can you upgrade? Edit: The output I get: http://imgur.com/iMZEMt9 – Torbjørn T. Apr 05 '14 at 15:12
Could you please update your post and make it a full working example starting with \documentclass... and ending with \end{document}. It will help solvers to start working on it. – Malipivo Apr 05 '14 at 15:12
make sure to How do I update my TeX distribution? – cmhughes Apr 05 '14 at 15:14

@cmhughes I removed all the old packages and by following the description provided by you solved the problem. Can you add as an answer, therefore I can accept it. – Mokus Apr 06 '14 at 12:46
@run that's great, I'm glad your problem has been resolved :) In such a situation, I'll vote to close your question as it has been resolved by updating your distribution – cmhughes Apr 06 '14 at 15:59
