Vertical Text Alignment in circled Nodes

[localghost]

Hello,

It seems that I have a lot of questions these days.

I am drawing two ellipses and two circles with tikZ:

Code: Select all  •  Open in writeLaTeX

\begin{tikzpicture}
  \node[ellipse, draw] at (0,0) {
    \begin{tikzpicture}
      \node at (0,0.2){$blablabla$};
      \node at (0,-0.2){$b$};
    \end{tikzpicture}
  };

  \node[ellipse, draw] at (3.5,0) {
    \begin{tikzpicture}
      \node at (0,0.2){$b$};
      \node at (0,-0.2){$blablabla$};
    \end{tikzpicture}
  };

  \node[circle, draw] at (0,3.5) {
    \begin{tikzpicture}
      \node at (0,0.2){$blablabla$};
      \node at (0,-0.2){$b$};
    \end{tikzpicture}
  };

  \node[circle, draw] at (3.5,3.5) {
    \begin{tikzpicture}
      \node at (0,0.2){$b$};
      \node at (0,-0.2){$blablabla$};
    \end{tikzpicture}
  };
\end{tikzpicture}

The result is here:

As you can see the texts in the two ellipses are centered vertically whereas they are not in the circles. This is due to the fact that "blablabla" is longer than "b" but I don't understand why it's working for the ellipses only.

Is it possible to center vertically the texts in the circles without changing the coordinates of the nodes ?

Again I found the solution (sorry for posting). I give the answer it may help someone:

Code: Select all  •  Open in writeLaTeX

\node (a) at (6,0.2){$b$};
\node (b) at (6,-0.2){$blablabla$};
\node[draw, circle, fit=(a) (b)] {};

Thanks for sharing. However, your solution in form of a self-contained and minimal document would be preferable since it would be compilable out of the box for everybody else.

Indeed here is a compilable latex file:

Code: Select all  •  Open in writeLaTeX

\documentclass{article}

\usepackage[english]{babel}
\usepackage{tikz}
\usetikzlibrary{fit}
\usetikzlibrary{shapes}

\begin{document}

\begin{tikzpicture}
  \node[ellipse, draw] at (0,0) {
    \begin{tikzpicture}
      \node at (0,0.2){$blablabla$};
      \node at (0,-0.2){$b$};
    \end{tikzpicture}
  };

  \node[ellipse, draw] at (3.5,0) {
    \begin{tikzpicture}
      \node at (0,0.2){$b$};
      \node at (0,-0.2){$blablabla$};
    \end{tikzpicture}
  };

  \node[circle, draw] at (0,3.5) {
    \begin{tikzpicture}
      \node at (0,0.2){$blablabla$};
      \node at (0,-0.2){$b$};
    \end{tikzpicture}
  };

  \node[circle, draw] at (3.5,3.5) {
    \begin{tikzpicture}
      \node at (0,0.2){$b$};
      \node at (0,-0.2){$blablabla$};
    \end{tikzpicture}
  };
\end{tikzpicture}

\begin{tikzpicture}
  \node (a) at (6,0.2){$b$}; \node (b) at (6,-0.2){$itworksperfectly!$};
  \node[draw, circle, fit=(a) (b)] {};
\end{tikzpicture}

\end{document}

Thanks for the solution! And in this way, I could click on "Open in writeLaTeX" and immediately test your example, very good.

I did not notice. Great feature.
