Not quite the same, but you may get close if you play around with the tension.


    \draw[->] (-2,0) -- (2,0);
    \draw[->] (0,-2) -- (0,2);
    \draw[thick] plot [smooth,tension=1.5] coordinates{(1,1) (1.4,0.5) (0.4,-0.2) (0.6,-0.2) (0.2,-1.4) (-0.5,-1.1) (-1,-1.6) (-1.4,0.4)};

enter image description here

  • Can I somehow obtain the coordinates of the point at some arbitrary position on the resulting curve? – Dror Apr 11 '14 at 7:52
