# Drawing nodes by polar coordinates with translation

I have plotted 12 nodes in a circle with radius 2 and center (0,0) (I suppose). Now I want to plot it once more in the same figure but with centre (2,0), how could this be achieved? Many thanks for any help!

My current code:

\begin{figure}[h]
\centering
\begin{tikzpicture}
\foreach \a in {1,...,12}
{
\node[vertex] (u\a) at ({\a*30}:2){};
}
\end{tikzpicture}
\caption*{\footnotesize{Figure 3}}
\end{figure}


It looks like:

I have tried like ({\a*30}:2)+(2,0) but doesn't work.

• Try this: \begin{scope}[xshift=2cm] ... code as before ... \end{scope}. – Pier Paolo Jun 18 '15 at 22:18
• @Salomo What do you mean? You can draw edges the same way you did the nodes in both foreach statements. – Alenanno Jun 18 '15 at 22:56
• Not tested: \usetikzlibrary{calc} and then ($({\a*30}:2) + (2,0)$). See also tex.stackexchange.com/questions/31830/… – hpekristiansen Jun 19 '15 at 0:30
• @Hans-PeterE.Kristiansen Thanks!!! That is a perfect solution! – Salomo Jun 19 '15 at 0:45

si j'ai bien compris la question, une solution!

if I understand the question, a solution
