Graphics, Figures & Tables ⇒ Creating labeled (a, b, c, …) nodes with TikZ and foreach

[Howard87]

Hello everybody,

I'm trying to create a graph using TikZ with a foreach loop. I'd like to label the nodes with characters, but I'm unable to do so.

\def \n {5}
\foreach \s in {1,...,\n} {
\node[mynodestyle] (\s) at ({360/\n * (\s - 1)}:3) {$\s$};
}

(I've been inspired by http://www.texample.net/tikz/examples/cycle/.)

The nodes are named 1 to 5, but they should be named a to e instead. I could not find any chr(\s) function. The 5 is pretty much fixed, so a lookup/makro might also be appropriate.

Thank you for any hints.

Howard

Hm…

I now seem to having found a way to do it:

\def \n {5}
\foreach \x/\y in {1/a,2/b,3/c,4/d,5/e} {
\node[mynodestyle] (\y) at ({360/\n * (\x - 1)}:3) {$\y$};
}

At least I don't have to worry about node positioning any more.
