problem with ConTeXt bibliographic citations

Hi,

I'm running pgf 1.10 and ConTeXt 2006.08.08 and I get the following error:

(/home/kallen/texlive/2005/texmf-dist/tex/generic/pgf-1.10/generic/pgf/utilitie
s/pgfutil-context.def (./thesis.aux
! Undefined control sequence.
l.1 \citation
             {*}

It looks like pgf is not (yet) compatible with the bib module in ConTeXt. The file thesis.aux only has the
following three lines:

\citation{*}
\bibstyle{cont-no}
\bibdata{general.bib}

The ConTeXt bib module is quite different from the standard BibTeX used in LaTeX so it might need special attention.

Hi!

this is more than a little strange since pgf has nothing to do with

Re: problem with ConTeXt bibliographic citations

Hi everyone,

it turns out that, indeed, the .aux writing of the bib module clashes  
with pgf's usage of the file of the same name. I renamed this stuff  
to .pgf and it works fine, now.

You will need to get the current CVS of pgf since the change is not  
quite trivial.

Alternatively, a quick-and-easy-fix is to find the file pgf/generic/ 
pgf/utilities/pgfutil-context.def and to delete the three lines  
having to do with .aux files at the beginning. Then picture  
remembering will not work (which it does in the CVS), but that may  
not be a top priority.

Best regards everyone,
Till

Dear Song Wei,

your "help request" is a bit cryptic and should better be send to the mailing list, but I'll try to answer anyway as I think this is "of general interest".

The idea is to use clippling excessively.

Suppose we have three circles or ellipses or whatever. Let us define commands for their paths since we will need them repeatedly in the following:

\def\firstcircle{(0:1cm) circle (1.5cm)}
\def\secondcircle{(0:1cm) circle (1.5cm)}
\def\thridcircle{(0:1cm) circle (1.5cm)}

Now we can draw the sets:

\draw \firstcircle;
\draw \secondcircle;
\draw \thirdcircle;

Now we want to highlight the intersection of the first and the second circle:

\begin{scope}
  \clip \firstcircle;
  \fill[red] \secondcircle;
\end{scope}

Next, we want the highlight the intersection of all three circles:

\begin{scope}
  \clip \firstcircle;
  \clip \secondcircle;
  \fill[green] \thirdcircle;
\end{scope}

When using the above, you will notice that the border lines of the original circles are erased by the intersection parts. To solve this problem, either use a background layer (see the manual) or simply draw the border lines after everything else has been drawn.

The intersection trick works pretty well for intersections. If you need the set-theoretic difference between two sets, things are a little more complicated:

Suppose we want to highlight the part of the first circle that is not also part of the second circle. For this, we need to clip against the "complement" of the second circle. The trick is to add a large rectangle that encompasses everything and then use the even-odd filling rule (see the manual again):

\begin{scope}% first circle without the second
  \clip[even odd rule] \secondcircle (-10,-10) rectangle (10,10);
  \fill[yellow] \firstcircle;
\end{scope}

Naturally, all of this could be bundled into nicer macros, but the above should give the idea.


Best regards everyone,
Till

PGF/TikZ example gallery

Dear PGF/TikZ users,

Recently a question was posted on the  PGF Open discussion forum if
there are any places to   find or upload pretty examples of drawings
made with pgf [1]. Now there is! I've been sharpening my Django [2]
skills and created an online gallery of PGF/TikZ examples with code
and results. The gallery is available at:

   http://www.fauskes.net/pgftikzexamples/

An example entry:
    http://www.fauskes.net/pgftikzexamples/global-nodes/

The gallery is still a work in progress, but I hope that it will
become a useful resource. I would therefore appreciate feedback on its
design, organization, features and such.

You are more than welcome to submit your own examples. Just send me an email.

Regards,
Kjell Magne Fauske

pgf/TikZ and ConTeXt

Dear prof. Tantau,

I believe that I have to address my problem directly to you ...

First I would like to thank you for this work. I am impressed what one 
can do with your package. On forthcoming saturday the Dutch TeX users 
group will have a gathering with a series of presentations. I will talk 
about pgf/TikZ with ConTeXt.

In the manual there is a graph which  calls gnuplot.
When  I adapt the code from the manual to run under ConTeXt I a row of 
errors (see at the end of the message) show up. After a couple of 
returns, gnuplot is correctly called. I get the required *.table file. 
Still there are errors but finally the graph is produced and placed.

Am I missing something?

Kind regards

Willi Egger

Help: about positioning TikZ picture


Hi, all,

I am new to TikZ and I tend to use it from now on. Unfortunately 
I encountered the problem of positioning the TikZ picture and still cannot 
find a way out after struggling the whole afternoon and night. Hopefully
someone here can help me out.

I met the problem when I try to use tikzpicture environment in Beamer. First
I 
tried following codes:

%----------------------------------------------------
\documentclass{beamer}
\usepackage{tikz}

\begin{document}

\frame[plain]{
    \center
    \begin{tikzpicture}
        \only<1-2>{
        \draw (-1,0) -- +(3.5,0);
        \draw (1,0) ++(210:2cm) -- +(30:4cm);
        \draw (1,0) +(0:1cm) arc (0:30:1cm);
        \draw (1,0) +(180:1cm) arc (180:210:1cm);
        \path (1,0) ++(15:.75cm) node{$\alpha$};
        \path (1,0) ++(15:-.75cm) node{$\beta$};
        \draw[red] (0,0) circle (2pt) node[anchor=south, color=red]
{$(0,0)$}; %
        }
        \only<2-3>{
            \path (1,0) ++(15:-2.75cm) node{$\gamma$};  }
    \end{tikzpicture}
}
\end{document}
%---------------------------------------------

I got two problem here:
1. the figure is not centered, and 
2. the overlays jump from frame to frame.

I looked up the PGF/TikZ manual and did not find the solution. In fact, I am
confused 
about the interaction between "column" environment in BEAMER and the TikZ
picture.
How can we put the TikZ drawing in the middle of the "column" space?

Thanks in advance!

changfa

Re: Help: about positioning TikZ picture

I think the problem is that the bounding box changes for each frame.
Try this instead:

\documentclass{beamer}
\usepackage{tikz}
\begin{document}

\frame[plain]{
   \begin{figure}
   \begin{tikzpicture}
       \useasboundingbox (-2,1) rectangle (3,-1);
       \only<1-2>{
       \draw (-1,0) -- +(3.5,0);
       \draw (1,0) ++(210:2cm) -- +(30:4cm);
       \draw (1,0) +(0:1cm) arc (0:30:1cm);
       \draw (1,0) +(180:1cm) arc (180:210:1cm);
       \path (1,0) ++(15:.75cm) node{$\alpha$};
       \path (1,0) ++(15:-.75cm) node{$\beta$};
       \draw[red] (0,0) circle (2pt) node[anchor=south, color=red]
{$(0,0)$}; %
       }
       \only<2-3>{
           \path (1,0) ++(15:-2.75cm) node{$\gamma$};  }
   \end{tikzpicture}
   \end{figure}
}
\end{document}

The above example works as intended. Try to experiment with the bounding box:
\useasboundingbox (-2,1) rectangle (3,-1);

You could for instance use
\useasboundingbox (0,0) rectangle (0.5,0.5);
to get a different placement.

Multiple label problem v1.09


Hello

I've this problem, i can't use multiple label :

\begin{tikzpicture}
\tikzstyle{vertex}=[shape=circle,draw=black,fill=gray!30,thick,inner  
sep =0pt,minimum size =3mm]
\node[vertex,label=above:$e^2$] (3)  {};
\end{tikzpicture}

above:$e^2$\pgf <at> nil \relax \XKV <at> srstate {}{ <at> \romannumeral \XKV <at> depth  
\ETC.
! File ended while scanning use of \tikz <at> parse <at> label.

but this works :

\begin{tikzpicture}
\tikzstyle{vertex}=[shape=circle,draw=black,fill=gray!30,thick,inner  
sep =0pt,minimum size =3mm]
\makeatletter
\protected <at> edef\ <at> tempa{\noexpand\node[vertex,label=above:$e^2$] (3)   
{};}\ <at> tempa
\makeatother;
\end{tikzpicture}

pgf 1.09

an idea of the problem ?

Thanks

Re: Multiple label problem v1.09

Hi,

The first example compiles without problem for me. Not sure what this
issue is but I am using v1.10 with tikz.code.tex v1.69 (from the CVS).

Hope this helps

Mark
