Negative interaction sign for directed edges

[qmarcou]

Hello! Thanks for putting this great work together! I would have one feature request in order to make your package suitable for my needs: I'm trying to draw a network where interactions are directed and can be either positive or negative which I would like to be able show graphically (showing positive interaction with a arrow head, and negative one with a dash, see here for example). Would it be possible to add this feature? Thanks!

Thank you very much for your comment. In fact, it would be helpful to simply change the look of the arrows. In the next version I will try to take this into account. In the meantime you can help yourself with the style option:

\documentclass{standalone}
\usepackage{tikz-network}
\begin{document}
\begin{tikzpicture}
% Vertices
\Vertex[x=0,y=-0,label=a]{A} \Vertex[x=3,y=-0,label=b]{B}
\Vertex[x=0,y=-1,label=c]{C} \Vertex[x=3,y=-1,label=d]{D}
\Vertex[x=0,y=-2,label=e]{E} \Vertex[x=3,y=-2,label=f]{F}

% Edges
\Edge[Direct](A)(B)
\Edge[style={-{Bar}, dashed}](C)(D)
\Edge[style={-{Turned Square[length=0.2cm,width=0.2cm]}}](E)(F)
\end{tikzpicture}
\end{document}

PS: An overview of all available arrow tips can be found in the TikZ & PGF manual section 16.5.
