I Need to reproduce a figure somewhat like the one here: Drawing Angles

The problem is that I get a figure wich differ from the original one: the arrow at the end of the spiral get vertical direction.

Arrow at the end of a spiral

What's wrong here.

            axis lines=middle,
            axis equal image,
            xtick=\empty, ytick=\empty,
            data cs=polar,
            \addplot [thick, black, smooth, domain=0:360] {1};
            \addplot [thick, red, -latex, smooth, domain=0:405] {0.3+x/2000} node [pos=0.9, anchor=south west] {$405^\circ$};
            \addplot [thick, black] coordinates {(0,0) (405,1)};
  • We really cannot possibly say what's wrong here without seeing where here is. Please post your code in the form of a small, complete document we can compile to reproduce the problem with the arrow. – cfr Sep 20 '15 at 12:01
  • I cannot reproduce the problem using the code you've posted. What version of pgfplots do you have and which version of TikZ/PGF? – cfr Sep 20 '15 at 13:20
  • I'm using v2.10 for both. – Hamed Sep 20 '15 at 14:16

    Then please upgrade. Then it will work. – user11232 Sep 20 '15 at 14:32

    I'm voting to close this question because it is solved by updating TikZ and/or PGFPlots. – Stefan Pinnow Nov 28 '16 at 20:09
