# multipart nodes anchors for dividers

How can a node be positioned at the center/edge of a part in a multipart node using relative positioning?

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{shapes.multipart}
\usetikzlibrary{positioning}
\begin{document}
\begin{tikzpicture}
\node[align=center,draw,shape=rectangle split,rectangle split horizontal,rectangle split parts=3, text width=2cm] (A) at (1.5,3)
{one\nodepart{two}two\nodepart{three}three};
\node[draw,shape=circle] (E) at (2.7,1) {$E$};
\node[draw,shape=circle] (C) at (3.7,1) {$C$};
\end{tikzpicture}
\end{document}


This is the desired result:

You mean like this?

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{shapes.multipart}
\usetikzlibrary{positioning}
\begin{document}
\begin{tikzpicture}
\node[align=center,draw,shape=rectangle split,rectangle split horizontal,rectangle split parts=3, text width=2cm] (A) at (1.5,3)
{$m$\nodepart{two}$0 \ldots 0$\nodepart{three}$r$};
\node[draw,shape=circle] (E) [below=of A.two split south] {$E$};
\node[draw,shape=circle] (C) [below=of A.three south] {$C$};
\end{tikzpicture}
\end{document}


The TikZ manual version 2.10, page 453 displays the anchors for the vertical split rectangle. You have to reinterpret for the horizontal version.

 not quite, I edited the code to make it more copy-pasteable. The E node should be horizontally aligned with (but appear below) the separator line separating partnode two and three. and C should horizontally be at the center of partnode three and also appear below (same y-coord as E) – Mish Jun 4 '12 at 19:47 I edited my answer. I hope it's ok now. :) – Count Zero Jun 4 '12 at 19:56 thank you so much, I didn't know about the split option. – Mish Jun 4 '12 at 20:02 @Mish: don't forget to upvote the answer (using the up arrow)- this gives Count Zero 10 reputation points, and is the best way to say thanks :) Also remember to upvote other answers that you find helpful on the site – cmhughes Jun 4 '12 at 20:08
