Nabble - PGF and TikZ

curved arrows and nodes of different width

2009-12-22T06:07:26Z

The first and last diagram are what I'm after, but my attempts to achieve this for the third one by "normal" means failed miserably, see the middle diagrams. (For some more hilarious results, try throwing in "\mathstrut" on each side!) What's the right way of doing this?

Re: pgffor in the CVS version (bug ?)

2009-12-22T02:06:12Z

Hi,

Yes, it seems in June 2008 I put some proposed extensions to pgffor in
the CVS and one of the changes was that test. I can't remember exactly
why I put it in as it is slower than the previous \ifx test but I
*think* that in the past you couldn't say {1, 2, ..., 10} (i.e.,
there was a problem with the spaces).

Regards

Mark

Re: pgffor in the CVS version (bug ?)

2009-12-22T01:36:22Z

Hi,

This is actually a problem with the macro \pgfutil@in@ which can be
used to test if a string A is contained in another string B .
Unfortunately if A consists of only one character (e.g., `...') and B
ends in that character (e.g., `feature.') this test will return a
false-positive.

\pgfutil@in@ is based on (it is exactly the same definition) as \in@
which is part of LaTeX. It is --- i believe --- the fastest way to
perform this kind of test and only fails in the case described above:

\documentclass{minimal}
\begin{document}

\makeatletter
\def\mytest#1{%
\expandafter\in@{...}{#1}%
\ifin@
`#1' contains the string `...'
\else
`#1' does not contains the string `...'
\fi}

\mytest{bug;}
\mytest{feature.}

\end{document}

The solution --- as you pointed out --- in this case is to put any `.'
in braces (or the whole list item).

Regards

Mark

Hi,

Following example gives me an error: ! Package tikz Error: Giving up

remove the \verb!...! in the node text.

\begin{tikzpicture}
\draw (0,0) rectangle (2,2);
\draw (.5,.5) node[fill=examplefill] {Text at \verb!node 1!}
-- (1.5,1.5) node {Text at node 2};
\filldraw[pink] (.5,.5) circle (1pt);
\end{tikzpicture}

This is copy from pgfmanual and I am test it with beamer. The command
line is 'pdflatex myfile'

Can anyone help? Thanks.

node[shift=...] does not work with scale (was: Scale , shift and foreach)

2009-12-18T05:35:28Z

I encountered the same issue as below with pgf 2.0.

The shift in 'node[shift=...] at (x,y)' seems not to work together with 'scale'. However
'node at ([shift=...]x,y)' seems to work! The \foreach seems not have any influence on this. Without
it the error appears in the same way.

\begin{tikzpicture}[scale=1]
\foreach \x in {1,2,4,8}{%
\node at ([xshift=\x cm]0,0) {\x};%
}
\end{tikzpicture}

\begin{tikzpicture}[scale=.5]
\foreach \x in {1,2,4,8}{%
\node at ([xshift=\x cm]0,0) {\x};%
}
\end{tikzpicture}

Re: Scaling in circuitikz

Hi Bjorn,

Bjørn Kolbrek wrote:

[...]
But what do I do when the schematic is bigger/wider than what I can put
on one page? Scaling doesn't work properly. Using for instance
[scale=0.5] shortens the lines between the components, but the
components themselves are the same size, and the result is that they are
drawn on top of each other.

Is there a way to scale the components, or do I just have to accept that
I can\t draw too large schematics?

I encountered the same problems with the 'tikztimingtable' in my package 'tikz-timing'.
The 'scale' setting is only a coordinate scaling, not a general zoom.

You can easily scale the whole thing using the \scalebox{<factor>}{<material>} command from
the graphicx package. An other way is to enclose the whole thing in a tikz node as described in the post "howto to scale a complete graph correctly" (can be found e.g. here:
http://old.nabble.com/howto-to-scale-a-complete-graph-correctly-td22367062.html).

The described "transform canvas" option seems to have problems calculating the correct bounding box.

The 'transform shape' option is a standard TikZ/PGF option.

Re: Source of TikZ manual

2009-12-17T02:29:40Z

Quoting Clemens Helfmeier (clemensh@...):
> try ou TEXINPUTS=./:../../text-en pdflatex pgfmanual.tex

This should work, at least it does for me. Important: you have to do it in
the folder where pgfmanual.tex is situated.

I just copied the whole directory texmf/doc/generic/pgf. Within this
directory, there are directories version-for-*. I changed into the
directory version-for-pdftex, as that is the version I most often use, and
within that the directory 'en'. *There* I called the above (or make, which
does not much more than the above). It worked like a charm.

If this does not work for you, as you are already working with a copy of the
source, try if you can move all those files into one directory, then call
"pdflatex pgfmanual.tex". I did not check for duplicate filenames, which
might be a problem then.

Hope this helps,

Susan

Re: Data in Vector

2009-12-17T02:18:04Z

Hi,

The latest CVS versions of the math engine allow vectors and matracies
to be emulated as follows:

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

\def\myvector{{1,4,7,9,2,33,-1}}

\foreach\i in {0,...,6}{\pgfmathparse{\myvector[\i]}\pgfmathresult, }

\def\myidmatrix{{{1,0,0},{0,1,0},{0,0,1}}}

\tikz\foreach \i in {0,1,2}
\foreach \j in {0,1,2}
\node at (\j,-\i) {\pgfmathparse{\myidmatrix[\i][\j]}\pgfmathresult};
\end{document}

Although there is no convenient size or length functions (cf. matlab,
python etc) yet.

Yes. But still failed. I think this is a directory layout problem.
The Make file set the TEXINPUTS=../../text-en for me, it amounts to:

$ TEXINPUTS=../../text-en pdflatex pgfmanual.tex

but this result in:

kpathsea: Running mktextex pgfmanual.tex
! I can't find file `pgfmanual.tex'.
<*> pgfmanual.tex

But if without TEXINPUTS setting and do it directly:

$ pdflatex pgfmanual.tex

Try adding the 'transform shape' option:

\begin{tikzpicture}[scale=0.2,transform shape]
...

This should scale node sizes as well. Line widths are not scaled
though. If you need this, look up canvas transformations in the pgf
manual.

Hope this helps.

Hi David,

In pure TikZ you can use the externalization library (take a look at the
manual), otherwise the preview package might help you :

How can I use tikz to produce a standalone image of say, a rectangle,
that I can import into another document.

Spy tikz library

2009-12-15T08:32:34Z

Hello,

I'm playing with the Spy TikZ library. It works a bit like pst-lens :
the object to be magnified must be in a {tikzpicture} environnement. I'm
wondering whether it could be possible to have the library be able to
magnify anything in the current page (text, graphics, etc) that is not
in a {tikzpicture} environnement (by using absolute positionning,
overlay, remember picture, compile twice, ...).

Thank you.

Jack

Scaling in circuitikz

2009-12-15T04:33:04Z

Hi all,

I'm new on this list, and in the process of learning Tikz and
circuitikz. I have already created a few schematics using that package.

But what do I do when the schematic is bigger/wider than what I can put
on one page? Scaling doesn't work properly. Using for instance
[scale=0.5] shortens the lines between the components, but the
components themselves are the same size, and the result is that they are
drawn on top of each other.

Is there a way to scale the components, or do I just have to accept that
I can\t draw too large schematics?

Thanks,

Bjørn

No, I didn't. Thanks for pointing it out. It has some stuff I was looking for, but it seems it does not provide general grid macros. At least not in the way I would need them.

I think pgfplots can do most of it (it cannot make boxplots though) :

You can also use the tikz output from R.

I'm so sorry to bother you again! Is there really no way to shade areas between curves which where created using gnuplot?

(If that's the case I'll have to spend the next days changing all the table-files by hand and won't be able to make any adjustments afterwards - except changing table files again... by hand. My work is due by the end of the week and I thought shading areas would be a breeze considering all the fantastic things I've seen that can be done with tikz and pgf.

I have problems filling the area between curves. In the following example I chose linear graphs to be able to also show you what I want the the result to look like.

Or is there any other solution?

Is there a package which provides such extended grids already?

But still I can't compile the manual.

Hello Leo,

The file queried by TeX should be part of the git release (I checked

your latest 'git pull' did not work as expected? What happens if you do

Perhaps this is also interesting:
Recently, I started copying recent compiled developer version manuals to

so you can simply copy the .pdf files from there.

Problem with the spy tikz library

Hello,

I'm using TL09, pdflatex, and pgfCVS2009-12-05_TDS

#1

\draw [decoration=Koch curve type 2]

decorate{ decorate{ decorate{ (0,0) -- (2,0) }}};

\spy [green!50!black] on (1.6,0.1) in node at (2.5,-0.5);

\end{tikzpicture}

\end{document}

Compilation error message :

! Package pgfkeys Error: I do not know the key '/tikz/magnifying glass'
and I a
m going to ignore it. Perhaps you misspelled it.

See the pgfkeys package documentation for explanation.
Type H <return> for immediate help.
...

This error message was generated by an \errmessage
