Graphics, Figures & Tables ⇒ Drawn Picture not centered

[sgu]

Hi all,

the tikzpicture environment seems to fail to center sometimes. The following is such an example.

Code: Select all

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{arrows,calc,positioning,shadows,shapes}

\begin{document}
  \begin{figure}[!htb]
    \centering
    \begin{tikzpicture}
      \draw[help lines] (-6.0,-6.0) grid (6.0,6.0);
      \node[align=center, fill=red!20, rounded corners=14pt, minimum height=2cm, minimum width=4cm] (chbox) at (0,0) {A};
      \node[align=center, fill=red!20, rounded corners=14pt, minimum height=2cm, minimum width=4cm] (meshbox) at (-6.0,0) {B};
      \node[align=center, fill=red!20, rounded corners=14pt, minimum height=2cm, minimum width=4cm] (imagebox) at (6.0,0) {C};
    \end{tikzpicture}
    \caption{Figure caption}
    \label{fig:dummy}
  \end{figure}
\end{document}

Any fix? Thanks.

Very good example. It makes the probable cause comprehensible at first sight and thus it's quite easy to fix it.

The picture itself is simply too wide. You should get a corresponding warning in the log file (*.log). Simply scale it down by the scale option for the tikzpicture environment. The option is described in Section 22.3 of the PGF/TikZ user guide.


Best regards and welcome to the board

The scale option seems not to work well with the minimum height and minimum width options.

Code: Select all

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{arrows,calc,positioning,shadows,shapes}

\begin{document}
  \begin{figure}[!htb]
    \centering
    \begin{tikzpicture}[scale=0.3]
      \draw[help lines] (-6.0,-6.0) grid (6.0,6.0);
      \node[align=center,fill=red!20,minimum height=2,minimum width=4] (chbox) at (0,0) {A};
      \node[align=center,fill=red!20,minimum height=2,minimum width=4] (meshbox) at (-6.0,0) {B};
      \node[align=center,fill=red!20,minimum height=2,minimum width=4] (imagebox) at (6.0,0) {C};
    \end{tikzpicture}
    \caption{Figure caption}
    \label{fig:dummy}
  \end{figure}
\end{document}

Add the transform shape option either as global option to the tikzpicture environment or locally for every single \node. The option is described in Section 16.7 of the PGF/TikZ user guide.

That solves the problem, thank you.
PGF has a lot of options and it looks like the PGF/tikz manual have very good examples to demonstrate the capability of the package but doesn't list all the options and all values for a option. And the PGF package has massive source codes. Any recommended way to find out the complete list of the options and all possible values for a given option? Thank you.

Actually the PGF/TikZ user guide lists all available options. How else would you find the right one for a problem? Perhaps you should browse the user guide by topic, not by keyword.
