[Tex/LaTex] Tikz multiline node with center align

horizontal alignmentline-breakingnodestikz-pgf

I have a problem with nodes in scheme. I need type a node where will be text "Banka melovskych filtru". Each word on a special line with center align.

Best Answer

You can use the align=center option. See the manual for further text options.

\begin{tikzpicture}
\node[align=center] {Banka \\ melovskych \\ filtru};
\end{tikzpicture}

[Tex/LaTex] Vertically center a node with the current line in TikZ

Add baseline=(current bounding box.center) as option to the tikzpicture and \tikz command. This places the baseline of the diagrams at its center and will cause a vertical alignment with the other baselines(!).

However, if you want to align it with the vertical center of the text, i.e. the center of "is", which looks most likely better, use
baseline={([yshift=-1ex]current bounding box.center)} instead. Adjust the value for your liking. Maybe .8ex might be better (an uppercase letter is about 1.6ex).

\documentclass{article}

\usepackage{tikz}

\begin{document}

  This is a
  \begin{tikzpicture}[baseline={([yshift=-.8ex]current bounding box.center)}]
    \node[draw, rectangle, align=left] {%
      And here \\[.3em]
      is
      \tikz [baseline={([yshift=-.8ex]current bounding box.center)}]
        \node[draw, rectangle, align=center] {a \\ nested};
    };
  \end{tikzpicture}
  one.
\end{document}

Result

Some other hints:

In general you can use \raisebox{<length>}{<content>} to raise or lower some material. You can use then \height, \depth, \width and \totalheight to refer to the original dimensions of the content. Use \dimexpr to do math:

\raisebox{\dimexpr-.5\height+.5\depth+.8ex\relax}{<content>}

There is also \vcenter{...} which will center things vertical, but it is intended to be used in mathmode.

[Tex/LaTex] Tikz node alignment

You can use an appropriate anchor for the "Data" node to place the node "A" with respect to theis anchor; notice also that right of=... is a deprecated syntax and one should use the positioning library with the right=of... syntax. I also changed the old \tikzstyle syntax to the newer \tikzset syntax.

    \node [block, right=of B] (C) {C};
    \node [block, right=of C] (D) {D};
    \path [line] (data.east|-A.west) -- (A.west);
    \path [line] (A) -- (B);

As Qrrbrbirlbel suggested in his comment, one can define an auxiliary coordinate at (data.shape center -| data.east) and this allows to use right=of data-center east for the "A" node; this approach has the advantage that it allows to keep the original node distance:

\usepackage{amsfonts}

block/.style={
  rectangle,
  draw,
  text width=5.5em,
  text centered,
  rounded corners,
  minimum height=4em},
line/.style={draw, -latex'},
edge/.style={draw}
}

\begin{document}
\begin{figure}
\centering
\begin{tikzpicture}
    % Place nodes
    \node [draw, cylinder, shape border rotate=90, aspect=0.75, %
      minimum height=40, minimum width=60] (data) {Data};
% auxiliary coordinate to place the following node
    \coordinate (data-center east) at (data.shape center -| data.east);
    \node [block, right=of data-center east] (A) {A};
    \node [block, right= of A] (B) {B};
    \node [block, right=of B] (C) {C};
    \node [block, right=of C] (D) {D};
    \path [line] (data.east|-A.west) -- (A.west);
    \path [line] (A) -- (B);
    \path [line] (B) -- (C);
    \path [line] (C) -- (D);
\end{tikzpicture}
