Hi,
postactions and the markings decoration are your freinds here. See the
docs for details:
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{decorations}
\usetikzlibrary{decorations.markings}
%\usepackage{textcomp}
\begin{document}
\pgfdeclaredecoration{single line}{initial}{
\state{initial}[width=\pgfdecoratedpathlength-1sp]{\pgfpathmoveto{\pgfpointorigin}}
\state{final}{\pgfpathlineto{\pgfpointorigin}}
}
\tikzset{
raise line/.style={
decoration={single line, raise=#1}, decorate
},
label line/.style={
postaction={
decoration={raise=0pt,markings, mark=#1}, decorate
}
}
}
\begin{tikzpicture}
\draw [red, very thick] (0,0) -- (3,2);
\foreach \r in {-20,-15,...,20}
\draw
[
raise line=\r,
label line=at position 0.5 with {\node[sloped,above]{\tiny\r};},
->
]
(0,0) -- (3,2);
\end{tikzpicture}
\end{document}
Regards
Mark
