    This is a very great example for using multiple mindmaps, congratulations!

    But i have a problem: I’m using the latest TikZ build (date 2010-01-17), which results in much better color transitions between the nodes. But the circle connection bars in the background layer aren’t filled, there are just black outlines. I allready tried to use fill=black, … but this changes nothing. Does anybody have a clue how to fix this?

  • #2 Kjell Magne Fauske, January 26, 2010 at 8:14 a.m.

    I noticed the same thing while preparing the example for upload. I have informed the author about the issue.

  • #3 Frakturfreund, January 28, 2010 at 2:31 a.m.

    I played a little bit around to find a solution, and what does work is somethink like

    \begin{pgfonlayer}{background}
      \draw [draw=green,fill=black, decorate,decoration=circle connection bar] (n11) -- (n21);
    \end{pgfonlayer}
    

    But if i write -- instead of edge or circle connection bar instead of decorate,decoration=circle connection bar, it doesn’t.

    More fretful, somethink like

    \draw [draw=green,fill=black, decorate,decoration=circle connection bar]
      (n11) -- (n21)
      (n12) -- (n22);
    

    or

    \begin{scope}[draw=green,fill=black, decorate,decoration=circle connection bar]
    \draw (n11) -- (n21);
    \draw (n12) -- (n22);
    \end{scope}
    

    also doesn’t work.

    I fear that this may be more a error of the latest TikZ build instead of the example.

    PS: The Markdown interpreter seems to ignore code blocks :(

    This is what I did:

    \begin{pgfonlayer}{background}
       \path (kab) to[circle connection bar] (cod);
       \path (kch) to[circle connection bar] (alg);
       \path (kch) to[circle connection bar] (gen);
       \path (lhc) to[circle connection bar] (med);
       \path (ksh) to[circle connection bar] (dec);
       \path (ndr) to[circle connection bar] (mat);
       \path (otr) to[circle connection bar] (opt);
       \path (otr) to[circle connection bar] (csm);
       \path (otr) to[circle connection bar] (img);
       \path (raf) to[circle connection bar] (alg);
       \path (raf) to[circle connection bar] (gen);
       \path (rbk) to[circle connection bar] (res);
       \path (rbk) to[circle connection bar] (mat);
       \path (sht) to[circle connection bar] (log);
       \path (sht) to[circle connection bar] (dec);
       \path (ver) to[circle connection bar] (qin);
       \path (ver) to[circle connection bar] (cod);
    \end{pgfonlayer}
    

    It seems that the 2010-01-17 build of TikZ has a bug with the edge command.

    I'm sorry if it's a silly question, but is it possible to change the text size? I'm trying to make the Mind Map fit on a A4 with scale and transform shape, but the text becomes almost unreadable due to its size... Any hint?

  • #6 liar, August 24, 2010 at 2:49 p.m.

    @Quim Nuss: like in any LaTeX file, you can change text size with \tiny, \small, \large, \Large, \LARGE, huge, etc.

    @KF: I had also some pbs: only the first edge appeared. According to my tests (sorry I read not other docs ;{), it seems that the problem came from the fact that I used a ';' at the end of each edge command/line. It seems that the pgfonlayer in this case works only if there is one single line of command.

    Hi I'm working with the beamer package, but i can make the map fit in the slide, How can I make it fit inside the slide?

    thanks!

  • #8 Jdbaba, June 15, 2013 at 2:49 a.m.

    @joeparram: you can use the following command to include the map fit in the slide.
