TikZ

\documentclass{article} \usepackage{tikz} \begin{document} \begin{tikzpicture} \node[fill=yellow!80!black,align=right, minimum width=10cm] {This is a\\ demonstration text for\\ alignments.}; \end{tikzpicture} \begin{tikzpicture} \node[fill=yellow!80!black,align=left, minimum width=10cm] {This is a\\ demonstration text for\\ alignments.}; \end{tikzpicture} \end{document} When using align=right and align=left, the text is usually flushed to the right. But when I set a minimum width for the box it appears in the center instead: This feels like a bug in tikz. In Left alignment in TikZ, people suggested setting text width or wrapping the content in a parbox. However, these require knowing the width of the text beforehand, otherwise one gets overfull/underfull box warnings, so I do not consider them real solutions. I would expect the text width to be chosen automatically.

I have the following situation: where the first \clip in the second frame is very small and I wish to present it a bit bigger for visibility reasons. I'm unsure how to tweak the code I'm using and if it is possible by simply using tikz + clip. Thanks in advance! MWE \documentclass[aspectratio=149]{beamer} \usepackage[T1]{fontenc} \usetheme{Singapore} \usecolortheme{dolphin} \usepackage{tikz} \usepackage[export]{adjustbox} \begin{document} \begin{frame} \frametitle<2>{Inset 1} \frametitle<3>{Inset 2} \only<1-3>{ \centering\includegraphics<1>[width=.75\textwidth]{example-image-a} \begin{adjustbox}{max width=\textwidth,max height=\textheight} \begin{tikzpicture} \clip<2> (-6,4) rectangle (6,5); \clip<3> (-6,-3.25) rectangle (6,-7.5); \node<2-> at (0,0) {\includegraphics[width=\textwidth]{example-image-a}}; \end{tikzpicture} \end{adjustbox} } \end{frame} \end{document} EDIT: sketch attempt Cropped from the original, the image can be stretch vertically, primarily, and horizontally up to the size of the frame while preventing Overfull hbox warnings. Proportion should be preserved but if not possible a vertical stretch has the priority.

Claim This post is more likely asking for better approach, focused on the arc's plot. And that is similar to, but I don't find the same one: Drawing cyclic quiver Drawing a circular graph using xypic https://tex.stackexchange.com/a/759710/322482 Descrption I found that just with： \draw[<->,shortstyle,violet] (\ang:\RR cm) arc[radius=\RR cm,start angle=\ang,delta angle=\deltaang]; The arc is not exactly centered at (0,0)(the violet part), thus I learnt from here and calculate the \deltaangg with cosline rule manually. Code \documentclass[tikz,border=5pt]{standalone} \usetikzlibrary{arrows.meta} \begin{document} \def\NN{5} \def\RR{5} \def\rr{0.5} \def\deltaang{\fpeval{360/\NN}} \def\deltaangg{\fpeval{acosd((2*\RR^2-\rr^2)/(2*\RR^2))}} % cosine rule \begin{tikzpicture}[ thick,>=Stealth,shortstyle/.style={shorten >=\rr cm,shorten <=\rr cm}] \foreach \i in {1,...,\NN}{ \def\ang{\fpeval{\deltaang*(\i-1)}} \path[draw,fill=gray!75] (\ang:\RR cm) circle[radius=\rr cm]; \def\startang{\fpeval{\ang+\deltaangg}} \def\endang{\fpeval{\ang+\deltaang-\deltaangg}} %%%%%%%%%%%%%% \draw[<->,shortstyle,violet] (\ang:\RR cm) arc[radius=\RR cm,start angle=\ang,delta angle=\deltaang]; %%%%%%%%%%%%%% % https://tex.stackexchange.com/a/66265/322482 \draw[<->,magenta] ([{shift=(\startang:\RR cm)}]0,0) arc[radius=\RR cm,start angle=\startang,end angle=\endang]; \foreach[parse=true] \j in {2,...,{\NN-2}}{ \def\nextang{\fpeval{\ang+\deltaang*\j}} \draw[shortstyle,<->] (\ang:\RR cm) -- (\nextang:\RR cm); } } \end{tikzpicture} \end{document} Question The magenta arcs is what I want, but I found it too hard to calculate \def\deltaangg{\fpeval{acosd((2*\RR^2-\rr^2)/(2*\RR^2))}}. Any suggestions on the code?

I apologized if this is a duplicate. What is the best way to draw such figures with tikz (or other packages)? For the time being just the potato like figure. I do not care for the vectors and the infinitesimal mass element. I do not want someone to do the work for me. Just some advice or suggestions.

I would like node B to have exactly the same width as node A, without explicitly specifying a fixed dimension, with the following constraints: The two nodes are not adjacent in the source code. I do not want to hard-code a width (e.g., minimum width=3cm). Node A will always be at least as wide as node B. I would prefer a solution that does not rely on manually computing dimensions via \path let unless necessary. Here is a minimal example illustrating what I currently have: \documentclass{article} \usepackage{tikz} \usetikzlibrary{calc} \begin{document} \begin{tikzpicture} \node [draw] (A) {Some text}; \path let \p1 = (A.south west), \p2 = (A.north east) in node [draw, minimum width=\x2-\x1-\pgflinewidth, minimum height=\y2-\y1-\pgflinewidth, below right] at ([yshift={\pgflinewidth}]A.south west) {more}; \end{tikzpicture} \end{document}

Consider the following minimal example where I want to draw a rectangle behind a sequence of numbers (to highlight them): \documentclass{article} \usepackage{tikz} \usetikzlibrary{backgrounds,calc} \NewDocumentCommand{\tikzmark}{ m }{\tikz[overlay, remember picture] \node (#1) {};} \newcounter{seq} \NewDocumentCommand{\seqstart}{}{% \stepcounter{seq}% Start a new sequence \tikzmark{seq-start-\theseq}}% Set start marker \NewDocumentCommand{\seqend}{}{% \tikzmark{seq-end-\theseq}% Set end marker \tikz[remember picture, overlay] \scoped [on background layer] \fill [fill=blue!10!white] ($(seq-start-\theseq.south west) + (-0.5pt,1pt)$) rectangle ($(seq-end-\theseq.south east) + (0.5pt,1.1\normalbaselineskip)$);% } \begin{document} \[ 12, 15, 8, 11, 4, 7, 0, 3, 16, 19, 12, 15, 8, 11, 4, 7, 0, 3, \ldots \] \[ \seqstart{}12, 15, 8, 11, 4, 7, 0, 3, 16, 19\seqend{}, 12, 15, 8, 11, 4, 7, 0, 3, \ldots \] \end{document} The idea is that \seqstart would set a (counter-driven) \tikzmark representing the start of the sequence to be marked. Then \seqend would set a \tikzmark at the end and highlight it using the background layer. The counter allows for multiple such sequence marking within a larger document. However, the output shows that the rectangle highlighting a part of the sequence is not being drawn on background layer as requested. Why is that? How can I ensure the rectangle is drawn on the background layer behind document/text elements? The backgrounds library documentation (in the tikz documentation, section 45) mentions that on background layer can only be used inside a {scope} or \scoped, which is done above.

The question is similar to this solution, but not the same: \documentclass[tikz, border=1cm]{standalone} \usetikzlibrary{decorations.pathreplacing} % https://tex.stackexchange.com/a/572738/322482 \begin{document} \begin{tikzpicture}[ rounded corners=1pt, path decomposition/.style={% postaction={decoration={show path construction, lineto code={ \draw[#1] (\tikzinputsegmentfirst) -- (\tikzinputsegmentlast); }, curveto code={ \draw[#1] (\tikzinputsegmentfirst) .. controls (\tikzinputsegmentsupporta) and (\tikzinputsegmentsupportb) ..(\tikzinputsegmentlast) ; }, closepath code={ \draw[#1] (\tikzinputsegmentfirst) -- (\tikzinputsegmentlast) {closepath};} } ,decorate}}] \draw[line cap=round, black, double=gray!10, thick, path decomposition={black, double=gray!10,thick}] (3,3) -- (1,1) -- (3,1) -- (1,3); % here below is what I want with only one path \begin{scope}[xshift=3cm] \draw[black, double=gray!10, thick, line cap=round] (3,3) -- (1,1) -- (1.5,1); \draw[black, double=gray!10, thick, line cap=round] (2.5,1) -- (3,1) -- (1,3); \draw[black, double=gray!10, thick] (1.3,1) -- (2.7,1); \end{scope} \end{tikzpicture} \end{document}

I found this post and I'm trying to retrieve the version shown in the image below. Does anyone know how I can get that specific version?

Also luamplib code is welcome.

I want to draw the following commutative diagram in LaTeX: I have tried tikzcd, but I think I won't work, since the rows have different size. Is there a clean way to do it?

I'm writing a mathematical paper that studies the fundamental groups of surface bundles, hence I need to create images of surfaces of genus greater than 1 with loops drawn on surface. What packages can I use to make such images? See page 8 of this paper for an example of such a surface.

(spy.aux)) No pages of output. Transcript written on spy.log. Sorry, but "MiKTeX Compiler Driver" did not succeed. I do not use Asymptote very often, so I am not sure about the cause of the problem. It is possible that the solution is related to what is discussed in the following TeX.StackExchange threads: 'filename-1.pdf' not found Asymptote Asymptote Code Generates .asy Files, But Asymptote Execution Fails In particular, I have not yet tried the solution proposed by the user user279206, and I do not know whether there is an alternative approach that would allow me to compile the document correctly with my MiKTeX distribution. In a previous question, I also asked whether it is possible to obtain the same arrow tip styles provided by Asymptote using TikZ: Arrows with spherical (conical) tips Since I do not understand Asymptote code, I kindly ask whether it would be possible to modify the original code by removing everything that is not strictly necessary, in order to obtain only the figure related to spherical coordinates, without the volume element and without additional unnecessary details to obtain this with the portion of a sphere. In TikZ there is a result: https://tikz.net/spherical_1/ This is my goal:

How can I draw the following arrow?

I'm working with a blank Beamer presentation template and want to recreate a sidebar similar to one shown in the image below. Unlike typical Beamer sidebars that extend to the page's edge, this one is part of a custom frame. I'd like the sidebar to display boxed sections with sharp drop shadows. The current section should be highlighted by a red shadow, while the current subsection should be bolded and appear on a white horizontal strip. Subsections from other sections should remain hidden until the presentation reaches that specific section, at which point they should appear in a dropdown list in the sidebar (e.g. in the image, we're on SO so subsections of SO are shown in the sidebar, but subsections of Section Two and Section Three are not). Note: By 'subsection' I really mean slide titles. How can I implement this effect in LaTeX? Any help would be appreciated. \documentclass[11pt]{beamer} \usepackage{tikz} \usepackage{microtype} \usepackage{xcolor} \usepackage{soul} \usetikzlibrary{calc} \usepackage{ lmodern, babel, amsmath, eurosym } \definecolor{darkpastelgreen}{rgb}{0.01, 0.75, 0.24} \usepackage[default]{sourcesanspro} \usepackage[T1]{fontenc} \setbeamertemplate{navigation symbols}{} \setbeamertemplate{background}{% \begin{tikzpicture}[overlay,remember picture] \fill[sharp corners,fill=darkpastelgreen] ($ (current page.north west) + (0.4cm,-0.4cm) $) rectangle ($ (current page.south east) + (-0.4cm,0.4cm) $); \end{tikzpicture}% \begin{tikzpicture}[overlay,remember picture] \fill[sharp corners,color=white] ($ (current page.north west) + (0.5cm,-0.5cm) $) rectangle ($ (current page.south east) + (-2cm,0.5cm) $); \end{tikzpicture}% } \setbeamersize{text margin left=0.8cm, text margin right=0.85cm} % Reduce side margins \setbeamertemplate{frametitle}{\color{black}\bfseries\insertframetitle \nointerlineskip \bigskip } \addtobeamertemplate{frametitle}{\vspace*{0cm}}{\vspace*{-0.4cm}} \addtolength{\headsep}{0.6cm} \begin{document} \begin{frame}[t]{} \frametitle{A Subsection} Slide content goes here... \end{frame} \end{document}

I want to draw this picture, but I can't How can help me?

I'm putting together a beamer presentation, and in a moment of madness I had the idea to give it a sort of lightbox/microfilm/transparency effect, sort of like this or this or this. I tend to keep my slides very simple, so this is new territory for me. The only thing I can think to do is some sort of tikz gradient, but that doesn't really get me what I want: \documentclass{standalone} \usepackage{tikz} \usepackage{tcolorbox} \begin{document} \begin{tikzpicture} \fill [black!20] (-0.5,-0.5) rectangle (1.5,1.5); \path [pattern color=black!30] (-0.5,-0.5) rectangle (1.5,1.5); \tcbvignette{fade in=black} \end{tikzpicture} \end{document} That gives you more of a picture frame effect with mitered corners, as here: Is there another approach I can be taking? Is this even within the limits of tikz?

The basic setup is as follows: Let's say I have a folder Main on the lowest level, that contains a folder Sub and a file Main.tex, which has the following content: \documentclass{beamer} \usepackage{tikz} \usetikzlibrary{external, matrix} \tikzexternalize{Main} % taken from: http://tex.stackexchange.com/questions/136143/tikz-animated-figure-in-beamer \tikzset{invisible/.style={opacity=0}, visible on/.style={alt={#1{}{invisible}}}, alt/.code args={<#1>#2#3}{\alt<#1>{\pgfkeysalso{#2}}{\pgfkeysalso{#3}}},} \begin{document} \tikzset{external/export=false} \include{Sub/Sub} \end{document} In the folder Sub, I have another folder Tikzand a file Sub.tex, which has the following content: \tikzsetexternalprefix{Sub/Tikz/img_} \begin{frame}{Test} \begin{figure} \tikzset{external/export=true} \tikzsetnextfilename{Test} \input{Sub/Tikz/Test.tikz} \end{figure} \begin{itemize} \item A \item B \end{itemize} \end{frame} In the folder Tikz I have a file Test.tikz, which has the following content: % taken from: http://tex.stackexchange.com/questions/136143/tikz-animated-figure-in-beamer \begin{tikzpicture} \matrix (magic) [matrix of nodes, ampersand replacement=\&, column sep=7mm, row sep=5mm]{ \node (se) [draw,shape=rectangle,visible on=<5->] {Existence Forte}; \& \node (yw) [draw,shape=circle,visible on=<1->] {Yamada-watanab}; \& \node (ul) [draw,shape=rectangle,visible on=<9->] {Unicité en Loi}; \\ \node (d1) [draw,shape=circle,visible on=<6->] {Définition}; \& \& \node (d2) [draw, shape=circle,visible on=<8->] {Définition}; \\ \node (we) [draw, shape=rectangle,visible on=<2->] {Existence Faible}; \& \node (ec) [draw, shape=circle,visible on=<10->] {Engelbert-Cherny}; \& \node (pu) [draw, shape=rectangle,visible on=<3->] {Unicité Trajectorielle}; \\ }; \draw[->, thick,visible on=<6->] (se) -- (d1); \draw[->, thick,visible on=<7->] -- (we); \draw[->, thick,visible on=<4->] (we) -- (yw); \draw[->, thick,visible on=<5->] (yw) -- (se); \draw[->, thick,visible on=<11->] (se) -- (ec); \draw[->, thick,visible on=<11->] (ul) -- (ec); \draw[->, thick,visible on=<12->] (ec) -- (pu); \draw[->, thick,visible on=<4->] (pu) -- (yw); \draw[->, thick,visible on=<8->] (pu) -- (d2); \draw[->, thick,visible on=<9->] (d2) -- (ul); \end{tikzpicture} What I now want to achieve is, that every page from the file img_Test.pdf (generated by compiling the code) is shown on its own frame in the presentation with the items A and B below, so it looks like an animation if one is clicking down the slides. But what I currently get is just a one-paged pdf showing just the first page of the figure and no items. If I just set tikzset{external/export=true} to false, everything works just fine, so it is just the externalization that causes this problem. I'm using the TeX Live distribution from the official Ubuntu repositories, do the editing with TeXstudio and compile with PdfLaTeX using the command pdflatex -synctex=1 -interaction=nonstopmode --shell-escape %.tex. The --shell-escape command is non-default, but I need it to get my tikz pictures compiled.

I often need to represent hierarchies within tables but I've yet to find an elegant way to do this. Oftentimes I do a variation on the following theme, with nested whitespace in the category column: \documentclass{article} \usepackage{booktabs} \newcommand{\lvl}{~~~} \begin{document} \begin{tabular}{lr} \toprule \textbf{Category} & \textbf{\%}\\ \midrule Animal & 100 \\ \lvl Human & 50 \\ \lvl\lvl Man & 20 \\ \lvl\lvl Woman & 30 \\ \lvl Fox & 30 \\ \lvl\lvl Vixen & 16 \\ \lvl\lvl Dog & 14 \\ \lvl Chicken & 20 \\ \lvl\lvl Cock & 8 \\ \lvl\lvl Hen & 12 \\ \bottomrule \end{tabular} \end{document} I might mix that up with midrules between categories and different fonts for different levels and so on. But the result can sometimes be very "busy", especially if there's a bunch of levels. Instead, I was playing around with the idea of adding lines to more elegantly represent the hierarchy, sketched as follows in red (a similar effect in the same spirit would also suffice): But I'm not sure how to realise this in LaTeX in an elegant way. I'm guessing I could somehow decorate a table with TikZ but I'd only know how to specify manual points (e.g., I'm not sure how to anchor rows in a table). Thus I'm looking for any suggestions of elegant solutions to achieve the above effect. (An ideal answer would avoid explicit coordinates/distances and would be "highly reusable".)

How can I get a linebreak inside a matrix node? The following gives the error: Package tikz Error: Giving up on this path. Did you forget a semicolon?. unless I remove the linebreak. \documentclass{standalone} \usepackage{tikz} \usetikzlibrary{chains} \usetikzlibrary{matrix} \begin{document} \begin{tikzpicture} \matrix (m) [ matrix of nodes ] { {some text} & {this node \\ does not work} \\ {other text} & {more text} \\ }; \end{tikzpicture} \end{document}

I want to join the vertices labeled as (1), b, abc, and ac but could not succeed. I'd highly appreciate if you point me out what I'm doing wrong and what is the solution. Thanks \documentclass{standalone} \usepackage{tikz} \usetikzlibrary{calc} \begin{document} \begin{tikzpicture}[scale = 4, fill opacity = 1.0, thick, line cap = round, line join = round] %% Define coordinate labels. % t(op) and b(ottom) layers \path \foreach \layer/\direction in {b/{0, 0, 0}, t/{0, 1, 0}} { (\direction) \foreach \point/\label in {{0, 0, 0}/ll, {1, 0, 0}/lr, {1, 0, -1}/ur, {0, 0, -1}/ul} { +(\point) coordinate (\layer\label) } ($(\layer ll)!0.5!(\layer ur)$) coordinate (\layer md) }; % Put text next to the labels as requested. % Funilly enough we need to set fill opacity to 1. \draw \foreach \text/\label/\anchor in {% $\left(1\right)$/bll/east, $b$/bul/east, $c$/tll/east, $bc$/tul/east, $a$/blr/west, $ab$/bur/west, $ac$/tlr/west, $abc$/tur/west} { (\label) node[anchor=\anchor, fill opacity = 1] {\text} }; % Draw cube. \fill (0, 0, -1) circle (0.5pt); \foreach \direction in {(0, 0, 1), (0, 1, 0), (1, 0, 0)} { \draw[dashed, black] (bul) -- + \direction; } \fill[red!60, opacity=0.5] (tll) -- (tul) -- (bur) -- (blr); \fill[blue!60, opacity=0.5] (bll) -- (bul) -- (tur) -- (tlr); \draw (bll) -- (blr) -- (tlr) -- (tll) -- cycle; \draw (blr) -- (bur) -- (tur) -- (tlr) -- cycle; \draw (tll) -- (tlr) -- (tur) -- (tul) -- cycle; \foreach \point in {bll, blr, bur, tll, tlr, tul, tur} { \fill[fill opacity=1] (\point) circle (0.75pt); } \node[below] at (1.0, -0.2, 0.0) {$AC$}; \end{tikzpicture} \end{document}

I want to draw a math matrix in TikZ, where I can draw helping partition lines. So far I found it pretty simple to just draw a matrix with brackets. \begin{tikzpicture} \matrix [matrix of math nodes,left delimiter={[},right delimiter={]}] { 1 & 2 & 1 & 0 & 0 & 10 \\ 3 & 2 & 0 & 1 & 0 & 20 \\ -2 & -10 & 0 & 0 & 1 & 0 \\ }; \end{tikzpicture} However, I would like to partition the matrix with a vertical line between columns 5 and 6, and a horizontal line between rows 2 and 3. Furthermore it could nice to have "identification variables" outside the brackets (top).

How can I do this diagram with tikz?
