Hi,
I use tikZ to draw graphs. In the picture below, I'd like to indicate that the vertices `v_1` , `v_2` and `v` have neighbours that are not shown in the picture. I was thinking about a little cone or something similar, but I've no idea how to implement that. - Code: Select all • Open in writeLaTeX
`\documentclass[11pt,a4paper]{article}` \usepackage[T1]{fontenc} \usepackage{tikz} \begin{document} \begin{figure}[!ht] \centering \tikzstyle{vertex}=[circle,draw, minimum size=12pt,inner sep=0pt] \tikzstyle{edge}=[draw,-] \tikzstyle{weight}=[font=\small] \begin{tikzpicture} \foreach \pos/\name in {{(1,3)/v_1}, {(1,2)/v}, {(2,2)/w_2},{(0,2)/w_1},{(1,1)/v_2}, {(2,3)/v_3}} \node[vertex] (\name) at \pos {$\name$}; \foreach \source/ \dest /\weight in {v_1/v/5, v_1/w_1/3,v_1/w_2/3,v/w_1/2, v/w_2/2, v_2/v/5 , v_2/w_1/3 , v_2/w_2/3, v/v_3/1 } \path[edge] (\source) -- node[weight] {} (\dest); \foreach \vertex in {} \path node[selected vertex] at (\vertex) {$\vertex$}; \end{tikzpicture} \end{figure} \end{document}
It would be great if someone could help me out here or just post an example. Thanks in advance Richard - RichardLang
