Paths to composite nodes

Anakreontas Mentis — 2013-04-05T11:45:55

Hello.

I have a diagram where nodes contain tikzpicture environments, each of
them have an automaton. The problem is that when I draw lines from on
node to an other, both the target and the source of the connecting
arrows are misplaced.

I have uploaded the latex code at http://pastebin.tlhiv.org/bl1my4rH

Initially, I placed the nodes in a matrix but when the arrows where not
drawn correctly I tried an alternative placement of the nodes. The
result was different but still wrong.

test again

shortening of braces

Zarko F. Cucej — 2013-03-24T15:30:43

Hi,
many times i need togive some description to groups of successive 
(rectangle) shapes, i.e. something like this:

\documentclass[tikz]{standalone}
     \usetikzlibrary{decorations.pathreplacing}
\begin{document}
     \begin{tikzpicture}[
box/.style = {draw, minimum size=9pt,inner sep=1pt, outer sep=0pt, right},
brc/.style = {decorate, decoration={brace,raise=1mm}},
shorten <>/.style = {shorten >=#1pt, shorten <=#1pt}
                     ]
\coordinate (a0) at (0,0);
\foreach \x [count=\xi from 0] in {1,...,4}
   \node[box] (a\x) at (a\xi.east) {\x};
\draw[brc] (a1.north west) to node[above=2mm] {A} (a2.north east);
\draw[brc] (a3.north west) to node[above=2mm] {B} (a4.north east);
\draw[brc,shorten <>=1] (a2.south east) to node[below=2mm] {C} (a1.south

\draw[brc,shorten <>=1] (a4.south east) to node[below=2mm] {D} (a3.south

changing braces coordinates. so i try to use shorten, but res

Re: patterns

Zarko F. Cucej — 2013-03-24T14:46:38

Dear Mark,
thank you very much for your answer. if i understood correctly, then i 
need to define separate "\pgfdeclarepatternformonly" for each patters, 
for example for horizontal, vertical, north west lines, gridetc?if this 
is a case, than it seems sensible to me, integrate them in the patterns 
library. is this possible?

best regard,    Zarko

Re: patterns

Mark Wibrow — 2013-03-24T07:20:02

Hi,

I _think_ this does it. The pattern bounding box is set probably a bit 
too big, but I was getting unexpected effects in my non-acrobat viewer 
(evince).


\documentclass{article}

\usepackage{tikz}
\usetikzlibrary{patterns}
\parindent=0pt
\begin{document}

\tikzset{
% There is possibly a bug in the patterns code so variables must
% always be expanded on assigment.
pattern line width/.estore in=\patternlinewidth,
pattern line width=1pt,
pattern line sep/.estore in=\patternlinesep,
pattern line sep=4pt,
}

\pgfdeclarepatternformonly[\patternlinewidth,\patternlinesep]{North East 
Lines}%
{\pgfpoint{-\patternlinewidth}{-\patternlinewidth}}%
{\pgfpoint{\patternlinesep+\patternlinewidth}{\patternlinesep+\patternlinewidth}}%
{\pgfpoint{\patternlinesep}{\patternlinesep}}%
{
   \pgfsetlinewidth{\patternlinewidth}
   \pgfpathmoveto{\pgfpoint{-2*\patternlinesep}{-2*\patternlinesep}}
   \pgfpathlineto{\pgfpoint{2*\patternlinesep}{2*\patternlinesep}}
   \pgfusepath{stroke}
}

Zarko F. Cucej — 2013-03-23T18:37:12

Hi,
in pgf manual the patterns description is described very, very shortly ...

so i like to know, if it is possible to define for example line width 
for north east lines patterns?

hi,

you appear to have missed a comma between 3.0 and 2.0:

\draw [fill=none] (3.0 2.0) arc (0:90:1.0 and 1.0) ;

Anything tikz cannot make sense of in a coordinate it thinks is a shape.

Partial circle

Lutz Gehlen — 2013-03-21T16:47:42

Hello everybody,
I am trying to draw a circular arc, but somehow cannot get it to 
work. The minimal example I've put together based on my 
understanding of the documentation looks like this:

\documentclass{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\begin{scope}
\clip (0cm,0cm) rectangle (8cm,3cm) ;
\begin{scope} [color=black]
\draw [fill=none] (3.0 2.0) arc (0:90:1.0 and 1.0) ;
\draw [fill=none] (2.0, 2.0) ellipse (1.0 and 1.0) ;
\end{scope}
\end{scope}
\end{tikzpicture}
\end{document}

Drawing the ellipse works fine (if I comment out the line with the 
arc command), but with the arc I get the following output:

Re: calculation of width of the rectangle shape

Zarko F. Cucej — 2013-03-17T20:12:33

log10(10) is just dummy example. actual value can presents some 
parameters, which are described in node and its width illustrate/expose 
one of them.

of course, the similar can be achieved by pgfplot with its bar plot and 
logarithmic scale, but there are limited possibilities to describe 
something in bars. actually for this purpose is legend ...

Forgive my complete naivety, but why can log10(10)

calculation of width of the rectangle shape

Zarko F. Cucej — 2013-03-17T06:25:18

hi,
is there a way to "on-line" calculate the minimum width of rectangle 
shape? something like:
%-------
     \documentclass{standalone}
\usepackage{tikz}
     \usetikzlibrary{shapes}
         \begin{document}
      \begin{tikzpicture}
\node[draw,minimum width=<math expression> mm] {?};
     \end{tikzpicture}
%-------
i try for math expression to use something like:

     \pgfmathparse{3*log10(10)}\pgfmathresult

but it giveserror:

! incomplete \iffalse; all text was ignored after line ...

please help me!

regards,    zarko

Re: multipart node: why empty par is not ignored?

Zarko F. Cucej — 2013-03-16T23:28:52

sorry for above unfinished letter, my computer send it without my 
willing during unexpected shout-down ...

to finish my question:

and why the empty part is omitted when in style I use instead "text 
width" the "minimum width"? is this a bug?

another issue happens when i try to colouring a parts. For example with:

rectangle split part fill={teal!10,teal!10,%
teal!20,teal!20,teal!20,teal!20}

than third part of node become white instead to stay in predefine 
colour! see
%---------------------------------------------------------------%
     \documentclass{standalone}
\usepackage{tikz}
\usetikzlibrary{shapes,shapes.multipart}
         \begin{document}
     \begin{tikzpicture}[
PP/.style n args = {3}{name=n#1,
                        rectangle split parts=#2,
                        minimum width=#3mm,
             rectangle split, draw, very thin,
             rectangle split ignore empty parts=true,
             rectangle split part fill={teal!10,teal!10,%
teal!20,teal!20,teal!20,teal!20}}

rectangle split, how difficult is to determine parameter for height of each par?

Zarko F. Cucej — 2013-03-16T00:12:20

Hi,
i often use rectangle split for sketch of comparison of the 
communication models. there it will be quit handy if for not empty shape 
parts will exist similar macro as for empty parts:

     rectangle split empty part height=<length>

or even better, if it will be capable to consider different height for 
each shape parts as this do

     rectangle split part fill={color-1, color-2, ...}

for colour of shape parts, i.e. th macro should have the following syntax:

rectangle split part height = {height 1, height 2, ...}

now i help myself with use of rules in each part with width=0 and 
desired height. This is not quite an elegant solution ...

any help in defining desired macro i will very appreciated!

regards,    Zarko

you can use right of instead cardinal points  to obtain frames aligned by

\draw[help lines](0,0) grid (10,1);

\node[draw,text width=3cm] (a) {some long, long text};

\node [draw,below right=0mm and 12mm,text width=1.5cm, right=of a] (b)
{some long, long text};

\node [draw,below right=0mm and 12mm,text width=1cm,right=of b] (c) {short};

\node [draw,below right=0mm and 12mm,right=of c] (d) {.};

both shapes aren't in the line? and why they are not the same shape (the
