Graphics, Figures & Tables ⇒ problem with tikz intersections

[Bahurin]

I have some problem with tikz. I want to get a curve and a several parallel arrows. But ends of arrows are unpredictable.

This is my code:

Code: Select all

\begin{figure}[h!]
\begin{center}

\begin{tikzpicture} [>=latex]

%\draw[->] (-4.0 cm, 0.0 cm) -- (10.0 cm, 0.0 cm) node[below]{$\omega$} ;
%\draw[->] (0.0 cm, 0.0 cm) -- (0.0 cm, 3.5 cm) node[right]{$S(\omega)$};

\draw[-, thin, dashed,rounded corners=0.14cm, name path=S] 
(0.00cm, 3.0cm) -- 
(0.25cm, 3.0cm) -- 
(0.50cm, 2.0cm) -- 
(1.00cm, 1.0cm) --
(1.25cm, 0.8cm) -- 
(1.50cm, 0.5cm) -- 
(1.75cm, 0.4cm) -- 
(2.00cm, 0.4cm) --
(2.25cm, 0.3cm) --
(2.50cm, 0.3cm);

\path [name path=v] ( 0, 0) -- ( 0, 5);
\draw [->, name intersections={of=v and S, by=y}, thick] (0, 0cm) -- (y);

\path [name path=v1] ( 0.25, 0) -- ( 0.25, 5);
\draw [->, name intersections={of=v1 and S, by=X}, thick] (0.25, 0cm) -- (X);

\path [name path=v2] ( 0.5, 0) -- ( 0.5, 5);
\draw [->, name intersections={of=v2 and S, by=X}, thick] (0.5, 0cm) -- (X);


\end{tikzpicture}
\end{center}
\end{figure}

result is very strange

What is my problem? How can I get a parallel lines?

I cannot reproduce the problem.

Code: Select all

\documentclass{article}
\usepackage{tikz}

Hi Bahurin,

Johannes' Code seems to work fine. You can click on "Open in WriteLaTeX" to have it compiled independently of your TeX version. Do you see any difference to your code?

I cannot test your code, since it's not compilable. It would be better if you would post complete codes in case of a problem, in the meaning of a minimal working example. In such a case, all would be clear, and a solution is nearly guaranteed.
