minmap and beamer

Hi,

I'd like to use a mindmap on a beamer slide, just a node and three 
children. While it is easy to generate the node/children, the picture as 
a whole is slighly too large to fit on the slide. Yet I haven't been 
able to find a option to 'scale' the mindmap picture or two decrease the 
size of the central node. Any advice would be greatly appreciated.

minimal example:
\documentclass{beamer}

\usepackage[T1]{fontenc}
\usepackage[latin1]{inputenc}

\usetheme{AnnArbor}
\usepackage{tikz}
\usetikzlibrary{mindmap,trees}

\begin{document}
\begin{frame}
	\frametitle{Text goes here}
	\tikzstyle{every annotation}=[fill=black!20]
\begin{tikzpicture}
\path[mindmap,concept color=blue,text=white]
node[concept]{Text}
	[clockwise from=330]
	child[concept color=green!50!black]{%
			node[concept](trans){trans}}
	child[concept color=red!50!black]{%
			node[concept](viral){viral}}

The (|x|y)scale option? See the manual for more info. This can be used on 
the tikzpicture as a whole (\begin{tikzpicture}[scale=.5]) or for paths
elements (\draw[scale=2] ...) and (?) nodes.

Yes, indeed. Kjell Magne Fauske gave me that hint about the 'scale' 
option , too, together with a 'transform shape': [scale=.8,transform 
shape] did the job.

Thank you!

Nodes are by default not affected by transforms. To scale the mindmap use

\begin{tikzpicture}[scale=0.9,transform shape]
....
\end{tikzpicture}

To change the size of the root node you can use:

\tikzstyle{root concept}+=[minimum size=1.5cm, text width=1cm]

(experiment with minimum size and text width)

I'll give that a try as well.

Thanks.

isolating nested tikz code from outer tikz code

Hello,

I've got some macros that create a new, combined symbol using tikz code:

\newcommand{\lp}{{\protect\mathord{
   \tikz{
     \useasboundingbox node[inner sep=0pt,outer sep=0pt] {\ensuremath{\p}};
     \draw[line width=.08ex,-] ++(-.35em,-.9ex) -- +(.5em,0ex);
   }
}}}

\newcommand{\up}{{\protect\mathord{
   \tikz{
     \useasboundingbox node[inner sep=0pt,outer sep=0pt] {\ensuremath{\p}};
     \draw[line width=.08ex,-] ++(-.17em,.89ex) -- +(.5em,0ex);
   }
}}}

It (under|over)lines P better than \(under|over)line does. The [-]-option 
was added to avoid external tikz styles having an effect.

However, when I include this in a tikzpicture, strange things happen:

\begin{tikzpicture}[baseline]
   % axes
   \draw[->] (-1,0) -- (1,0) node[below] {};
   \draw[->] (0,-1) -- (0,1) node[left] {};
   % desirable gambles
   \shade[bottom color=lightgray,top color=white,shading angle=-45] (0,0) coordinate (O) -- (-.4,1)
coordinate (top) -- (1,1) -- (1,-.3) coordinate (bottom) -- cycle;

Re: isolating nested tikz code from outer tikz code

Hi!

first, I think \newcommand should have an argument [1] and \p should  
read #1, right?
second, the wrong placements seem to be due to changing anchors. Try
\useasboundingbox node[inner sep=0pt,outer sep=0pt,anchor=center] ...

Perhaps anchor=base might be preferable and saying \tikz[baseline] so  
that the code can be used in normal text.

Hoping this helps,
Till

Indeed, something like that.

Thanks, this solves the positioning problem.

However, I stil have the problem that the symbol thus defined doesn't 
notice it's in math mode, or in a subscript (see minimal example below). 
How can I solve this?

---
\documentclass{article}
\usepackage{tikz}

\newcommand{\lp}{{
   \tikz[baseline]{
     \useasboundingbox node[inner sep=0pt,outer sep=0pt,anchor=base] (lp) {P};
     \draw[line width=.08ex,-] (lp.south west) ++(.03em,-.2ex) -- +(.45em,0ex);
   }
}}

Re: isolating nested tikz code from outer tikz code

Please lookup TeX's \mathchoice command, that will do the trick.

Re: TikZ for geometric drawings?


I know it is not TikZ, but haven´t you tried Mathspic?
http://www.ctan.org/tex-archive/graphics/mathspic/dos/mpicm21.pdf (old
manual, see page 14, 25)

Downloads: http://dante.ctan.org/indexes/graphics/mathspic/

I used the DOS version, I assume the Perl version works better. I think it
should solve some of your problems... like perpendiculars, middle point,
etc..
