mindmap

Hello,
I have able to change mindmap nodes to rectangles (squares) but I have not
had any luck changing them to actual rectangles the size, of which, I
determine. I would also like to be able to use elliptical nodes. Thanks in
advance for any advice. I did check this forum for possible solutions to
this problem.
Regards,
Tom

Good example, for example, at

Don't miss \tikzstyle{every picture}+=[remember picture]

Re: loading libraries and \jobname in \tikzexternalize

The whole purpose of \tikzexternalize is to compare the argument against the 
current \jobname, so there cannot be a way to compute the argument from the 
\jobname.

*However*, AFAICS it could be possible to let the main document  
create "foo.mainjob" files for every figure "foo", so that \tikzexternalize 
can later read the main job's name from \jobname.mainjob.  If 
\jobname.mainjob does not exist, it would simply default to \jobname.

Wouldn't that work?

Yes, it would create yet another (potentially large) set of output files which 
adds to the usual TeX cruft, but it would have a large benefit in terms on 
convenience, no?

Personally, it has often bitten me, for example
1) when quickly transferring preamble parts from one document to another or
2) when renaming documents
and forgetting to change the main jobname, respectively.

HTH,
  Hans

That is exactly what often happens to me, and I need quite some time to find out
that I just forgot to change the real jobname.
Even worth is it, when I give my preamble to a colleague (who is not so familiar
with LaTeX and or pgf/tikz) and then get a call or email why my preamble is not
working in his document ...

Re: loading libraries and \jobname in \tikzexternalize

Hello Hans, Hello Stefan,

Thinking about how the <real job name> argument can be eliminated, I
stumbled about a surprisingly simple, fully automatic solution. I have
just comitted a patch for the external library.

If you write
\tikzexternalize
or
\tikzexternalize[<options>]
*without* the real job name argument, it will be deduced automatically.

The deduction works simply by providing TeX code as argument to the
system call, try it out.

The modification is fully backwards compatible and should work with any
postscript specific system call as well (It modifies the '\texsource'
argument to the system call).

I have short time now, so I'd be glad if you could check the
modification and report any problems. I'll document the modification as
soon as I find time.

Best regards

Christian

how to access the node at the end of the pin?

Hello,
is there a way to access the node at the end of a pin?
As you can see from the attached example the "test2" pin nodes look a bit odd.

I would like to use the "test1" style and then just rotate the text inside of
this node. 

Best regards,
Stefan Pinnow

% ------- minimal -------
\documentclass{article}
    \usepackage{tikz}
\begin{document}
    \begin{tikzpicture}[
        pin distance=5ex,
        every node/.style={
            circle,
            draw,
        },
        test1/.style={
            minimum size=#1,
            pin={[
            ]above right:blabla}
        },
        test2/.style={
            minimum size=#1,
            pin={[
                red,
                rotate=45,
            ]right:blabla}
        },
    ]

        \node[test1=1cm]  at (0,0) {};
        \node[test1=5cm]  at (0,0) {};

        \node[test2=1cm]  at (6,0) {};
        \node[test2=5cm]  at (6,0) {};
    \end{tikzpicture}
\end{document}

pgf and xstring package

The number of argument of a macro is limited to 9, I think.
I wanted to pass a long series of parameters to a macro.
Using the xstring package I parse a chain ("12,13,14" in the example below).
It works ok as long as I don't use pgf commands in the macro.
Is there another way to proceed?

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[english]{babel}
\usepackage{xstring}
\usepackage{tikz}
\newcommand{\mymacro}[1]{
\def\a{\StrBefore[1]{#1}{,}} % 1st param
\def\b{\StrBetween[1,2]{#1}{,}{,}} % 2nd param
\def\c{\StrBehind[2]{#1}{,}} % 3rd param
param 1 = #1 \\
a=\a \\
b=\b \\
c=\c \\
%\pgfmathparse{\a} % Problems if you de-comment this line
}

\begin{document}
\mymacro{12,13,14} % this chain could be longer...
\end{document}

Thx

Legend for external plots

Hei,

I use pgf, tikz and recently pgfplots for my graphs. But I have a  
problem with large data sets. I am currently using gnuplot to generate  
the graphs viz.

set terminal postscript eps color
set noborder
set nokey
set output 'test.eps'
plot dataset_1.xy' u ($3):($2) t ""  w l lw 5 lt 1 lc 1, \
dataset_2.xy' u ($3):($2) t ""  w l lw 5 lt 2 lc 2, \
dataset_2.xy' u ($3):($2) t ""  w l lw 5 lt 3 lc 3

and include the output in my Latex file viz.

\begin{figure}[htb]
   \centering
   \topcaption{...}
   \begin{tikzpicture}
     \begin{axis}[
         axis on top,
         xlabel=X,
         ylabel=Y,
         grid=both]
       \addplot graphics[
         xmin=0,
         xmax=1,
         ymin=0,
         ymax=1,
         includegraphics={trim=12 9 12 8,clip}]{test};
%      \legend{soft}
     \end{axis}
   \end{tikzpicture}
\end{figure}

which works fine. However, I am not able to add a legend. It gives an  
error and complains, that pgfplots has encountered more than two  
coordinates.

How can a legend be included? If not, is there an alternative solution  
to generate plots based on large data sets? I don't want to use the  
package "datatool" if possible.

Thanks a lot in advance. And Sorry if this or a similar question has  
been asked before. But I could not something relevant in the archive.

Re: pgf and xstring package

Hello,
Yes indeed, I think you should look either at the package keyval (or its extension xkeyval) or the package
pgfkeys which is heavily used by pgf....
