TikZ

Consider the following MWE: \documentclass{beamer} %\documentclass{article} \usepackage{polyglossia} \usepackage{tikz} \setdefaultlanguage[babelshorthands]{italian} \usetikzlibrary{quotes,babel} \begin{document} \begin{frame} \shorthandoff {"} \begin{tikzpicture} \node ["la mia etichetta" red, draw] {il mio nodo}; \end{tikzpicture} \shorthandon {"} \end{frame} \end{document} compiled with latexmk --halt-on-error --file-line-error -pdflualatex=/usr/local/texlive/2025/bin/x86_64-linux/lualatex -lualatex foo.tex But it fails ./foo.tex:21: Undefined control sequence. \italian@sh@"@ ...next {''}\else \def \xpgit@next {\futurelet \xpgit@temp \x... l.21 \end{frame} My goal is to use quotes syntax to create a node as label. But in Italian " is an active char. So to fix this issue I loaded babel library and added \shorthandoff. Effectively, these two solutions work when article class is used. To be honest, with article only babel library is required. Anyway I must create a Beamer presentation. I would want to know if this is a bug or this behaviour is documented somewhere and I missed it.

I am trying to make a graph with weighted edges using tikz inside a beamer class (the documentclass seems to be irrelevant). I want the edge labels (weights) to have a \tiny font size but I am not sure how to ensure that. I looked around the tikz documentation and still am unsure. Below is my MWE: \documentclass[ aspectratio=1610, % PDF hyperlinks, with coloured links hyperref={bookmarks, breaklinks, % for line breaks in links colorlinks, pdftex, }, ignorenonframetext, notheorems, xcolor={table, % more colour options usenames, dvipsnames, }, ]{beamer} %% Fonts & languages \usepackage[utf8]{inputenc} % type Unicode characters \usepackage[T1]{fontenc} % font encoding \usepackage[english]{babel} % multi-language support %% Colours & graphics \usepackage{pgfplots} % for plots \pgfplotsset{compat=1.18} % set package options globally \usetikzlibrary{graphs, graphs.standard, quotes, } \begin{document} \begin{frame}[t] \centering \begin{tikzpicture}[scale=1] \graph [clockwise=5]{% A, B, C, D, E; A -- {B [> "6", {font=\tiny}], C, D , E }; B -- {C, D, E}; C -- {D, E}; D -- {E}; }; \end{tikzpicture} \end{frame} \end{document} This results in the following: In the figure, I would like the edge label 6 to be smaller in size than the node labels A-E. I tried edge node style with desired font size using quotes syntax: [> "6", {font=\tiny}]. However, that did not resolve the issue. Any suggestions are be welcome.

Is there a convention to denote in a genealogytree-tree structure that someone is not married anymore? And if not, is there be a possibility to e.g. dash the existing line between nodes S2 and W1 in the following example: \documentclass{standalone} \usepackage[all]{genealogytree} \begin{document} \begin{tikzpicture} \genealogytree[id suffix=@a]{ parent{ g[male, id=S2]{S2} p[female]{P1} p[male]{P2} } } \genealogytree[id suffix=@b, set position=S2@b at S2@a]{ parent{ p[female]{W1} p[male, id=S2]{S2} g[female]{D1} } } \genealogytree[id suffix=@c, set position=S2@c at S2@a]{ parent{ p[male, id=S2]{S2} p[female]{W2} g[phantom]{} } } \end{tikzpicture} \end{document}

I stumbled upon the issue where a phantom node position seems not to align with a regular node placed at the assumed position: \documentclass{standalone} \usepackage[all]{genealogytree} \begin{document} \begin{tikzpicture} \genealogytree[id suffix=@a]{ parent{ c[male, id=S2]{S2} c[female,phantom]{W2} g[male]{S1} p[female]{P1} p[male]{P2} } } \genealogytree[id suffix=@c, set position=S2@c at S2@a]{ parent{ p[male, id=S2]{S2} p[female]{W2} g[phantom]{} } } \end{tikzpicture} \end{document} The phantom node in the first tree-structure is used as a placeholder for the second tree. The added node from the second tree (W2) intersects the first tree (node S1). How can I align the phantom node with the "real" node? Please note as this is part of a larger tree I can't put the node W2 to the left of S2.

I want to draw this curve using LaTeX. I don't have any idea to do that.

In the following code, in the first plot I entered manually the rotated coordinates. In other words, each coordinate is transformed by the rotation matrix (using cos 25 and sin 25) as the function is sampled. In the second plot I use rotate=25 instead. \documentclass[tikz]{standalone} \usetikzlibrary{calc} \begin{document} \begin{tikzpicture} \draw let \n1={2pt} in plot({cos(25)*\x-sin(25)*\n1*\x},{sin(25)*\x+cos(25)*\n1*\x}) plot[rotate=25](\x,{\n1*\x}); \end{tikzpicture} \end{document} I think that two formulae are equivalent, but unexpectedly the two plots are not the same in the output. Why?

I want to create the following image: Here is my attempt. How to get the curvy like arrow as in the image? Thanks for any help! \documentclass[margin=5pt]{standalone} \usepackage{tikz} \usetikzlibrary{arrows.meta, shapes, positioning, fit} \begin{document} \begin{tikzpicture}[node distance=1.5cm and 1.5cm, font=\small, >=Stealth] % Message en clair et bloc de chiffrement \node[align=center] (plaintext) {Message\\(Texte en clair)}; \node[draw, rectangle, thick, fill=white, right=of plaintext] (encrypt) {\textit{chiffrement}}; \node[draw, dotted, fit=(plaintext)(encrypt), inner sep=8pt, label=below:Expéditeur] (senderbox) {}; \draw[->, thick] (plaintext)--(encrypt); % Canal de communication \node[right=3cm of encrypt] (comm) {canal de communication}; % Flèche du chiffrement vers le canal avec étiquette \draw[thick, ->] (encrypt) -- node[below, midway]{Texte chiffré} (comm); % Bloc de déchiffrement et message final \node[draw, rectangle, thick, fill=white, right=3cm of comm] (decrypt) {\textit{déchiffrement}}; \node[right=of decrypt] (finalmsg) {Message}; \node[draw, dotted, fit=(decrypt)(finalmsg), inner sep=8pt, label=below:Destinataire] (receiverbox) {}; \draw[->, thick] (comm) -- (decrypt); \draw[->, thick] (decrypt) -- (finalmsg); % Espion \node[below=1cm of comm] (eaves) {Espion}; \draw[dashed, ->, thick] (comm.south) to[out=-90,in=90] (eaves); \end{tikzpicture} \end{document}

I am trying to fill a path using gradient, but it is not working. the Entire path is solid color. I tried \path and \shade but the result is the same. How to fill the path with gradient? Adding transparency to the corners would be a plus in a seperate example. \documentclass[letterpaper]{article} \usepackage{tikz} \begin{document} \begin{tikzpicture} \pgfdeclarehorizontalshading{gradient}{100bp}{color(0bp)=(white); color(25bp)=(red); color(75bp)=(red); color(100bp)=(white)} \shade[shading=gradient, shading angle=0] (0,0) .. controls (0,2mm) and ({0.25*80mm},2mm) ..

Recently, I saw the following pictures in the lecture notes from my university's Machine Learning course. I am quite used to writing most of my assignments and other works with LaTeX, but I've never seen something like this before. I know that you can plot graphs using tikz, but how would I reproduce the structures (a decision tree and some partition of a square region) found in the attached image? Any help will be greatly appreciated.

When I teach the Baire category theorem, I write on the board the following diagram: I would like to have a TeX version of this diagram. The easiest possible solution would be with arrays, but then I can’t get the long underbraces and diagonal $\in$ symbols. Maybe this requires tikz? EDIT: this is what I managed to cook up with the help of some online tools and a lot of fiddling around. If anyone has a cleaner or better looking solution, I'm all ears. \documentclass{article} \usepackage{tikz} \usepackage{amsmath} \usepackage{amssymb} \usepackage{xcolor} \usetikzlibrary{decorations.pathreplacing, calc} \begin{document} \begin{tikzpicture}[x=1cm, y=-0.6cm, font=\footnotesize] % Constants \def\tab{0.7} \def\colstart{0} \def\rowskip{4} % distance in y between groups \def\subsetx{\colstart+6*\tab} % Top row \node[anchor=west] at (\colstart,0) {$V \qquad \cap U_1$}; \node[anchor=west] at (\subsetx,0) {$\subseteq V \cap U_1$}; % Underbrace \draw[decorate,decoration={brace,mirror,amplitude=5pt}] ($(0.0,0.3)$) -- ($(1.75,0.3)$); % Group Loop \foreach \n in {1,2,3} { \pgfmathsetmacro{\xbase}{\colstart + (\n)*\tab} \pgfmathsetmacro{\ybase}{(\n-1)*\rowskip + 1} % Vertical chain \node[anchor=west] at (\xbase,\ybase) {$\rotatebox[origin=c]{270}{$\supseteq$}$}; \node[anchor=west] at (\xbase,\ybase+1) {$\overline{B}_{\n}$}; \node[anchor=west] at (\xbase,\ybase+2) {$\rotatebox[origin=c]{270}{$\supseteq$}$}; \node[anchor=west] at (\xbase,\ybase+3) {$B_{\n} \qquad \cap U_{\the\numexpr\n+1\relax}$}; % Slanted x_n \node[red, rotate=30] at (\xbase-0.2,\ybase+3.4) {$x_{\n} \in $}; % Underbrace — only if not last group \ifnum\n<3 \draw[decorate,decoration={brace,mirror,amplitude=5pt}] (\xbase+0.0,\ybase+3.3) -- (\xbase+1.75,\ybase+3.3); \fi % Explicit intersection on RHS \edef\intersection{V} \foreach \k in {1,...,\the\numexpr\n+1\relax} { \xdef\intersection{\intersection\ \cap\ U_{\k}} } \node[anchor=west] at (\subsetx,\ybase+3) {$\subseteq \intersection$}; % Green arrow \draw[->, thick, green!70!black] (\xbase+0.6,\ybase+1.1) -- ++(0,-1.5) -- (\colstart+7*\tab,\ybase-0.4); \fill[green!70!black] (\xbase+0.6,\ybase+1.1) circle (2pt); } % Final line \pgfmathsetmacro{\finaly}{3*\rowskip + 5} \node[red] at (\colstart+4*\tab,\finaly) {$x_\infty$}; % Align the subseteq symbol with the others \node[anchor=east] at (\subsetx,\finaly) {$\in \overline{B}_n$}; \node[anchor=west] at (\subsetx,\finaly) {{\color{green!70!black}{$\subseteq V \cap U_1 \cap U_2 \cap \dots \cap U_n$}} $\quad \implies x_\infty \in V \cap \bigcap_{n=1}^\infty U_n$}; % Red path from x_1 to x_infty \draw[->, red, thick] (\colstart+1*\tab-0.45, 4.75) -- (\colstart+4*\tab-0.45, 1+4*4); \end{tikzpicture} \end{document}

Predefined TikZ patterns have always worked quite well for me, with one exception: I could never figure out how to set a specific "scale" or "zoom factor", so to say. Currently, I am creating graphs with shapes that span over the better part of an A4 page's width, hence in some cases, the provided patterns like north west lines are visually too dense. The following straightforward sketch visualizes what I would like to achieve, ideally without needing to create a pattern from scratch: MWE: \documentclass[margin=5mm]{standalone} \usepackage{tikz} \usetikzlibrary{shapes,patterns} \begin{document} \begin{tikzpicture} \draw[pattern=north east lines] (0,0) rectangle ++(4,4); \end{tikzpicture} \end{document}

I want to draw this image with tikz by using this code \documentclass{article} \usepackage{tikz} \begin{document} \begin{tikzpicture} % First matrix (4x3) \foreach \i in {0,...,2} { \pgfmathsetmacro{\value}{int(1+\i)} \draw (0,\i) rectangle ++(1,-1) node[midway] {\value}; \pgfmathsetmacro{\zeile}{int(3-\i)} \draw[<-,black] (1,1.5-\i) -- (2,1.5-\i) node[right] {\zeile.

I've been trying to include a monochromatic PDF vector figure in my LaTeX document and change its fill color directly within LaTeX, without using any external tools. I found two main solutions: Sol1: Setting the PDF color space to RGB and using the decodearray option in \includegraphics. Unfortunately, this method didn't work for me. Sol2: Using TikZ pictures. This method gave me better results but still isn't perfect. I'm running into two main problems with the TikZ method: Inconsistent Fill Color: Even though I used the same color for the top and bottom borders of the hlines in tblr, the colors of the figure and the \hline don’t look the same. Unwanted Background: The figure has a white background behind it, even though the original figure is black on a transparent background. I set fill=transparent!0 in the TikZ picture, but it didn’t fix the issue. Any suggestions on how to resolve these issues? Original figure is black (you can download it from here: "left_logo.pdf"). Shown on the right side of the attached image.

I have a little problem with the numbers that are supposed to indicate the size of the respective bars. These are a bit very far outside the actual diagram. Unfortunately, I can't see my mistake until now to adjust them accordingly, precisely because the diagram becomes much larger and no longer fits completely on the slide. \documentclass[10pt,% aspectratio=169,% ]{beamer} \usepackage[T1]{fontenc} \usepackage[utf8x]{inputenc} \usepackage{lmodern} \usepackage[english]{babel} \usepackage{pgfplots} \pgfplotsset{compat=1.18, /pgf/number format/use comma, table/col sep = comma} \usetikzlibrary{patterns} \begin{filecontents*}{tabellen/data1.csv} Substanz,x,Messung1,AbwMessung1,Messung2,AbwMessung2,Messung3,AbwMessung3,Messung4,AbwMessung4 Salzsäure [v\%/v],1,0.04,0.00,0.24,0.00,0.20,0.00,0.23,0.00 Natronlauge [g/L],2,0.00,0.50,0.78,0.44,0.54,0.00,0.88,0.00 Titanpentachlorid [g/L],3,0.00,0.00,1.39,0.05,0.00,0.00,0.99,0.00 Isopropanol [g/L],4,0.00,0.00,0.05,0.00,0.06,0.00,0.04,0.00 Benzol [g/mL],5,1.07,0.00,1.03,0.00,1.03,0.00,1.03,0.00 \end{filecontents*} \begin{document} \begin{frame}{Title} \begin{tikzpicture} \begin{axis}[ ybar=2pt, ylabel={Konzentration}, % width=\textwidth, height=\textheight, xticklabels from table={tabellen/data1.csv}{Substanz}, xtick=data, ticklabel style={/pgf/number format/.cd, use comma, 1000 sep = {}}, nodes near coords, every node near coord/.append style={ yshift=transformdirectiony(\myshift+1), anchor=center, rotate=90, font=\scriptsize }, ymajorgrids=true, legend pos= north east, legend cell align=right, ] \addplot [draw = blue, fill = blue!30!white, error bars/.cd, y dir=both, y explicit, error mark=triangle*, error bar style={color=black}] table[ x=x, y=Messung1, y error=AbwMessung1, visualization depends on=1.25*\thisrow{AbwMessung1} \as \myshift, ] {tabellen/data1.csv}; \addlegendentry{1.

I have a trouble in fixing the position of a tikzpicture when there is overlay. In the example, due to the overlay of the texts below the picture, the picture will float a bit. However, I would like the picture to be fixed at the exact position, such that when I scroll the pages the effect looks like only the text is changing but the picture doesn't move at all. Here is my example: \documentclass[10pt,xcolor={dvipsnames}]{beamer} \usepackage{tikz} \begin{document} \begin{frame}{title} \begin{center} \begin{tikzpicture} \tikzset{ round node/.style={circle,draw,inner sep=1.5} } \node [round node] (1) {1}; \end{tikzpicture} \end{center} \begin{itemize} \only<1>{ \item By convention, we do not draw the information sets that contain a single node \item Therefore, any uncircled (or unlinked) decision node should be understood as a \textbf{singleton} information set} \item<2> In Figure (b), \textbf{player 2 has two singleton information sets}: \begin{itemize} \item The left one: player 2 knows that player 1 has chosen H \item The right one: player 2 knows that player 1 has chosen T \end{itemize} \end{itemize} \end{frame} \end{document} Remark: I don't use \uncover or \onslide because I don't want to leave blank space.

I would like to start a graph's first node (G1) with respect to another pre-existing node (N1), using the positioning library. I would like it to appear as follows: N1 G1 - - G2 N2 I've included a MWE below. My first attempt was to specify \path[below=of N1] at the beginning of the graph, but that did not work as the G1 and the following graph were in line. My second attempt which brings me very close to what I want, is to define a coordinate [below=of N1](Gstart), and shift the graph. The slight issue with this is that G1 is slightly offset (see the red ink I've marked up the picture with). Note that I can position node N2 wrt the graph node G2 as I expected. \documentclass{article} \usepackage{tikz} \usetikzlibrary{positioning,graphs} \begin{document} \begin{tikzpicture}[inner sep = 0pt, outer sep = 0pt,] \tikzset{node distance = 1cm and 2cm} \node (N1) {N1}; %%% First attempt \path[below=of N1] graph [grow right sep=2cm]{ G1 -- P/ -- G2}; %%% graph doesnt start below if I try this %%% My solution, gets me a bit close, but the graph is horizontally offset a bit \coordinate [below=of N1](Gstart); \path[shift={(Gstart)}] graph [grow right sep=2cm]{ G1 -- P/ -- G2}; %%% graph doesnt start below \node (N2) [below=of G2] {N2}; \end{tikzpicture} \end{document}

I am currently working on a layout for a document (based on this post and this), using scrbook with scrlayer-scrpage. After a long struggle to get lines with rounded corners in the header and footer, everything works as expected -- except the numbering of the table of contents in the header. For some reason that I do not understand (I am sure because lack of basic knowledge) it gets a chapter number 0 and section number 0.0, instead of an empty field, which is the desired output for unnumbered chapters. When I compile my document with the slightly modified original code for the header no numbers are given for the table of contents. Based on this, my idea was to use \ifnumbered{chapter}{THEN}{ELSE}, either by redefining \chaptermarkformat and \sectionmarkformat (IDEA 1) or by changing the output for \lehead{} (and \rohead{} IDEA 2). What am I missing? Any help is much appreciated. Thank you in advance.

I am trying to create a node-network using pdflatex and have something very specific in mind. Below, you can find my current minimal example as a tex file that I have a problem with (compilable with pdflatex): \documentclass[tikz, 11pt,landscape]{article} \usepackage[default,osfigures,scale=0.95]{opensans} \usepackage[T1]{fontenc} \usepackage[utf8]{inputenc} \usepackage{tgbonum, tikz} \usetikzlibrary{shapes, calc, arrows.meta, fadings, decorations.pathmorphing, math} \usepackage[a3paper]{geometry} \begin{document} \thispagestyle{empty} \tikzset{normal/.style = {rectangle split, rectangle split horizontal, rectangle split parts=3, very thick, draw=black, inner sep=0cm, minimum height=0.6cm, text height=1.5ex, text depth=0.25ex}} \begin{tikzpicture}[remember picture, overlay] \path[draw, color=gray, thick] ($(current page.center) + (-10, 0)$) -- ($(current page.center) + (10, 0)$); \path[draw, color=gray, thick] ($(current page.center) + ( 0,-10)$) -- ($(current page.center) + ( 0,10)$); \node[normal] (66) at ($(current page.center) + ( 4.0, 2.0)$) {\nodepart[text width=6mm]{one} \nodepart{two}\rule[-0.25ex]{0pt}{1.75ex}\phantom{j}Node1\phantom{j}\nodepart[text width=6mm]{three}}; \node[normal] (75) at ($(current page.center) + (-4.0,-0.5)$) {\nodepart[text width=6mm]{one} \nodepart{two}\rule[-0.25ex]{0pt}{1.75ex}\phantom{j}Node2\phantom{j}\nodepart[text width=6mm]{three}}; %PROBLEM \draw[-{Latex[length=3mm]}, very thick] (66.west)--(75.east) node[midway,circle,inner sep=0.5mm,fill=white]{5}; \end{tikzpicture} \end{document} This creates a DIN A3 pdf with the following content (zoomed in to show the relevant part): The only part of the tex file that causes me headaches is the line after the "%PROBLEM"-comment. It draws the connection between the two nodes with a value in the middle. I want to be able to replace this arrow with an arrow that is basically cut in half, with a gap between the two parts, as seen in the following image (I'm giving you my best paint skills here): The middle should be transparent (not white, as this may overlay other things), and the number that was in the middle of the arrow before should be in the middle of the end piece. Furthermore, The arrow should be colorable (I could figure that out on my own I guess, but it's not my focus now) and I want to be able to control the length of the edge pieces as a fraction of the original distance. So for the situation below: I want to be able to change the lengths of the parts from 0.3 and 0.2 to 0.4 and 0.5 by just changing two numbers, and not a bunch of calculations. This is important, since this tex file will be programmatically generated and will contain many nodes, so I can't have a lot of special cases. I thought I might approach this by drawing two arrows instead of one and calculating the relevant points. First I calculate the end point (a) and the start point (b) and draw a connection: \def \a{($(75.east) - (current page.center) + (14.1, -10.9)$)}; \def \b{($(66.west) - (current page.center) + (14.1, -10.9)$)}; \draw[very thick] \b--\a; For some reason I do not know, the coordinate system of these seems to be offset. Through trial and error I found out that I could negate this offset by subtracting (current page.center) - (14.1, -10,9). This produces: So: Success. Then I calculate intermediary points (c) and (d) and try to draw two connections: \def \a{($(75.east) - (current page.center) + (14.1, -10.9)$)}; \def \b{($(66.west) - (current page.center) + (14.1, -10.9)$)}; \def \c{($\a + (0.3 * (\a - \b))$)}; \def \d{($\b - (0.2 * (\a - \b))$)}; \draw[very thick] \c--\a; \draw[very thick] \b--\d; Which does not compile with the error: Runaway argument? \a + (0.3 * (\a - \b ))$)--\a ; \draw [very thick] \b --\d ; \end {ti\ETC. ! Paragraph ended before \tikz@cc@parse@factor was complete. And I have absolutely no idea what to do about this. I did a bunch of trial and error without success: rearranging the formulas, trying different draw commands, with and without spacing, braces, parentheses and so on. I also tried to solve this with fading using something like this and making a color transparent, but that seems overly complicated and didn't succeed either. I guess my calculations are wrong? But I am simply way to much of a tex noob to understand why this is failing. I would be glad if any of you can help!

When I include the package tikz on my latex header, even if the package is not used at all, I get the following error at compiling time: Undefined control sequence. l.1131 \pgfdeclarearrow {name=|<->|, means={>[sep=0pt].|}} where l.1131 is line 1131 of the file "tikz.code.tex" A minimal example for this error is the following. \documentclass{article} \usepackage{tikz} \begin{document} test \end{document} So could be the mistake?

I have three images, I want to organize them in a frame to cause the effect of a zoom, similar to the image I have posted above. In this image the galaxy is at left, but i want to learn how to modified this position in the code, becouse acctually I need the second image(in our case, the Solar System) at right. It is no necessarily that one image overlap the other, but it is not a problem if this occurs I have no clue how to do it, any advice?

We have questions about Christmas trees and Hearts for Valentines but we have no questions that specialize in Halloween or Dia de los Muertos art. Here it goes: Using TikZ or PSTricks or any other of your favorite LaTeX tools, create pumpkins, ghouls, etc., appropriate to the season. I think multiple submissions should be fine provided different objects are created.
