TikZ

I'm typing some lecture notes in LaTeX, and I want the document to be accessible (PDF/UA compliant). Extra guidance on LaTeX PDF-accessibility would be helpful. My main point of concern is with figures, namely tikz pictures. Right now I have separate files containing only a block tikz code (i.e. they are not meant to be compiled as PDF on their own). Here is the code for one of the pictures (called 1-Robot_arm.tex): \tikzset{every picture/.style={line width=0.75pt}} %set default line width to 0.75pt \begin{tikzpicture}[x=0.75pt,y=0.75pt,yscale=-1,xscale=1] %uncomment if require: \path (0,499); %set diagram left start at 0, and has height of 499 %Shape: Rectangle [id:dp7996705832338366] \draw [fill={rgb, 255:red, 204; green, 199; blue, 199 } ,fill opacity=1 ] (292,271.57) -- (418.85,271.57) -- (418.85,292.03) -- (292,292.03) -- cycle ; %Shape: Triangle [id:dp46766492743083177] \draw (354.27,240.74) -- (372.57,271.05) -- (335.97,271.05) -- cycle ; %Shape: Ellipse [id:dp7340933088598973] \draw (349.44,235.75) .. controls (349.44,232.99) and (351.61,230.75) ..

However, instead of directly inputting tikz code into my main document, I want to render the tikz pictures as separate PDFs, and use \includegraphics in the figure environment (so I can reference them) in the main document to display the picture. Note that just wrapping the \input{1-Robot_arm} in the figure environment gives a "no bounding box" error in PAC. I referred to this StackExchange post 'Standalone' TikZ pictures and tried applying it to my own code with the figure environment and adding alt-text (compiling with LuaLaTeX).

Whilst constructing this minimal-working example (the above two code blocks) in a new project, I ran the main PDF through PAC, and it strangely passed all criteria, even though I effectively copied-and-pasted the code from my original project. So, this problem can be caused by something else in the main document, but I don't know what.

I'm using tikz to create a figure with a ring and n nodes on it equally separated by an angle of 360° / n. Since I want the number of nodes to be arbitrary I defined a command which creates the tikzpicture: \newcommand{\drawfigure}[2]{% \def\n{#1} \begin{tikzpicture} \draw[dashed] (0,0) circle (\rring); \foreach \i in {0,...,\numexpr\n-1\relax}{ \pgfmathsetmacro{\angle}{360*\i/\n} \begin{scope}[shift={(\angle:\rring)}, rotate=\angle] \draw[fill=black!20] #2; \end{scope} } \end{tikzpicture} } where \rring is defined globally, the first argument is the number of nodes to create and the second the node to draw. For example if one wants circular/rectangular nodes he can pass as second argument the macro \nodecirc/\noderect: \def\nodecirc{% (0,0) circle (\rnode); } \def\noderect{% (-\rnode,-\rnode) rectangle (\rnode,\rnode); } The problem I stumbled across is related to the bounding box of tikzpictures for specific values of n, and only with the circular node. For example for n = 3 I obtain a white space above the upper node, but not below the lower one as in this picture (sorry for the white backgrounds, if I added a background color the bounding box would get bigger, just open the image in a new tab): a similar problem arises for n = 5: but not for n = 4: while as I said with the rectangular node everything works fine. The issue persists if I set the bounding box as \usetikzlibrary{bbox} \tikzset{% bezier bounding box } the only difference being now some nodes are cut off, for instance the lower one in the case n = 3: Here is a MWE: \documentclass[tikz]{standalone} %\usetikzlibrary{bbox} \tikzset{% %bezier bounding box } \def\rring{1} \def\rnode{0.4} \def\nodecirc{% (0,0) circle (\rnode); } \def\noderect{% (-\rnode,-\rnode) rectangle (\rnode,\rnode); } \newcommand{\drawfigure}[2]{% \def\n{#1} \begin{tikzpicture} \draw[dashed] (0,0) circle (\rring); \foreach \i in {1,...,\n}{ \pgfmathsetmacro{\angle}{360*\i/\n} \begin{scope}[shift={(\angle:\rring)}, rotate=\angle] \draw[fill=black!20] #2; \end{scope} } \end{tikzpicture} } \begin{document} \drawfigure{3}{\nodecirc} \drawfigure{4}{\nodecirc} \drawfigure{5}{\nodecirc} \drawfigure{3}{\noderect} \drawfigure{4}{\noderect} \drawfigure{5}{\noderect} \end{document} How can I solve the problem, possibly without setting manually the bounding box? Why does tikz behave like this, it shouldn't since every node is placed symmetrically with respect to the origin? EDIT: as suggested by @gernot the problem seems to be related to how the bounding box of each node is calculated. See these examples: for n = 3, and for n = 5, while in the case n = 4 every bounding box is computed correctly. The bounding boxes were drawn replacing the scope environment with: \begin{scope}[shift={(\angle:\rring)}, rotate=\angle, local bounding box=bbox] \draw[fill=black!20] #2; \end{scope} \draw[red] (bbox.south west) rectangle (bbox.north east); Still I don't understand where's the problem, and why symmetric nodes don't have symmetric bounding boxes...

I have made a family tree using the geneologytree package like this: \documentclass{standalone} \usepackage[all]{genealogytree} \begin{document} \begin{genealogypicture}[ template=database traditional, ] parent[id=parents]{ p[id=father]{ male, name = {Jack Doe}, } p[id=mother]{ female, name = {Jane Doe}, } c[id=c1]{ female, name = {Jane Doe}, } c[id=c2]{ male, name = {‍Jack Doe}, } c[id=c3]{ male, name = {Jack Doe}, } g[id=c4]{ female, name = {Jane Doe}, } c[id=c5]{ female, name = {Jane Doe}, } c[id=c6]{ male, name = {Jack Doe}, } c[id=c7]{ male, name = {Jack Doe}, } } \end{genealogypicture} \end{document} This is the output: This picture is quite wide and I wish to make it fit into a thinner space. One way of doing this that I can think of is by changing the vertical position of the siblings so that the sibling nodes are arranged in a zig-zag manner. This would allow us the 'shrink' the horizontal space while still leaving enough room for the labels. Something like this: How can this be done? I am using the traditional database template.

But is there a way to make this tree grow horizontally from the left to the right? Instead of growing from top to bottom? I tried using the timeflow=right option, but it seems that has no effect on the traditional database template. I tried genealogytree because that seemed to be most suited for drawing family trees. Perhaps I should be using something else?

The following code compiles without error but gives unexpected (to me) results. In particular, the labels never 'settle'. As far as I can tell, LaTeX perpetually reports that the labels may have changed. The positions of the nodes jump from place-to-place (sometimes on different pages) accordingly. Now I know \subnode[]{}{} works - or did work. So either I am doing something very silly or something has broken (probably very recently) or both. \documentclass{article} \usepackage{tikz} \usetikzlibrary{tikzmark,fit} \begin{document} \begin{tikzpicture} \node {a \subnode{a}{sub} node}; \node [fit=(a),draw,inner sep=0pt,] {}; \end{tikzpicture} \end{document} This is essentially copy-pasted from tikzmark's manual, but I cannot get it to work. Certainly tikzmark does not seem to have been updated recently. However, pgf/tikz is from 2025-08-29 v3.1.11a (3.1.11a), so perhaps something has changed there. Another suspect may be LaTeX if anything to do with \mathchoice might have changed recently, since \subnode uses this internally.

I’m trying to annotate a quadratic Bézier* curve in TikZ with vectors. Right now I can draw normal vectors (red arrows) at multiple points along the curve using the decorations.markings library. Here is a minimal working example: \documentclass[tikz,border=5mm]{standalone} \usepackage{tikz} \usetikzlibrary{decorations.markings,calc,arrows.meta} % <-- arrows.meta added \begin{document} \begin{tikzpicture} % Quadratic Bézier control points \coordinate (QB1) at (0,0); \coordinate (QB2) at (0,3); \coordinate (QB3) at (8,3); % Convert quadratic to cubic control points \path let \p1 = (QB1), \p2 = (QB2), \p3 = (QB3), \p4 = ({(1/3)*\x1 + (2/3)*\x2},{(1/3)*\y1 + (2/3)*\y2}), \p5 = ({(2/3)*\x2 + (1/3)*\x3},{(2/3)*\y2 + (1/3)*\y3}) in coordinate (QB_aux1) at (\p4) coordinate (QB_aux2) at (\p5); % The curve \draw[thick,black] (QB1) .. controls (QB_aux1) and (QB_aux2) .. (QB3); % Normal vectors using arrows.meta syntax \draw[ postaction={ decorate, decoration={ markings, mark=between positions 0. and 1. step 0.1 with { \draw[color=red, -{Latex[length=1mm]}] (0,0) -- (0,0.5); } } } ] (QB1) .. controls (QB_aux1) and (QB_aux2) .. (QB3); \end{tikzpicture} \end{document} Now, in addition to the red arrows (normals), I would like to draw vertical and horizontal arrows at the same positions. However, it seems that TikZ rotates every arrow into the local coordinate system of the decoration. As a result, I cannot find a way to get all arrows to stay vertical/horizontal in the global picture. Also, I don’t want the red vectors to become the vectorial sum of the horizontal and vertical components — they are all independent drawings. Question: How can I place these vertical and horizontal arrows at each marked position along the Bézier curve, aligned with the global axes, rather than with the curve’s local frame? * For some reason, if I use \draw[thick,black] (QB1) .. controls (QB2) .. (QB3); instead of \draw[thick,black] (QB1) .. controls (QB_aux1) and (QB_aux2) .. (QB3); the curve doesn't look like a quadratic Bèzier.

I’m trying to recreate a figure from Roger B. Nelsen’s Proofs Without Words: Exercises in Visual Thinking—specifically “Sums of Squares V” (Integer Sums, p. 81).

Good morning: I am trying to reproduce the table at the end of page 394 of the manual. Essentially, I have summarized it to build an arrow that goes from the first tcbhightmath to the second, all within a tcolorbox. So far, I have not succeeded because the nodes are not recognized. I have tried with overlay, with after={code} and with tikz in different positions, inside and outside of the tcolorbox. It still doesn't work, so I appreciate any help. My last code is: \documentclass{article} \usepackage{amsmath} \usepackage{tikz} \usepackage[many]{tcolorbox} % Estilo de resaltado en fórmulas \tcbset{highlight math style={ enhanced, colframe=blue!70!black, colback=blue!10, boxrule=1pt, arc=2pt, outer arc=2pt, fontupper=\normalsize, drop fuzzy shadow }} % Hacer que TikZ recuerde los nodos \tikzset{remember picture} \begin{document} \begin{tcolorbox}[enhanced, colback=white] \begin{align*} \tcbhighmath[remember as=fx]{f(x)} &= \int_{1}^{x} \frac{1}{t^2}\,dt \end{align*} \end{tcolorbox} \vspace{2cm} % solo para separar las cajas en el ejemplo \begin{tcolorbox}[enhanced, colback=white] \begin{align*} f(x) &= \tcbhighmath[remember as=resultado]{1 - \frac{1}{x}} \end{align*} \end{tcolorbox} % Flecha entre las dos cajas \begin{tikzpicture}[remember picture, overlay] \draw[red, thick, ->, bend left] (fx.south) to (resultado.north); \end{tikzpicture} \end{document}

I want to draw two arcs in TikZ. Right now I’m using \path let to calculate the radius, but I’d like to store this value and reuse it later, so I don’t have to write the starting points every time. In particular, I want to calculate the distance 𝐴𝑆1 once, save it, and then use it as the radius when defining other points on the arc. I guess I should use \pgfmathsetmacro for this, but I’m not sure how. What is the best way to save a value (for example, the distance between two points) and reuse it in multiple \draw commands?

I want the combined cells have ticks. That is, My desired sketch is as below: I have consulted that there exists abovepos and belowpos in tblr. But it didn't work as below: \documentclass{article} \usepackage{tabularray} \begin{document} \begin{tblr} { colspec={*{6}{X[c,.5cm]}}, cells={font=\ttfamily}, cell{1-2}{3,5} = {c=2}{c}, cell{3}{1} = {c=6}{c}, hlines, % vlines, vlines={abovepos=-1,belowpos=-1} % not work } + & EXP & LEFT & & RIGHT & \\ + & 0 & UP & & DOWN & \\ CV & & & & & \\ \end{tblr} \end{document} Also, I have tried \UseTblrLibrary{tikz}, but it not so smart, because the position of which should have tick is regular(only for combined cell).

I want to plot y = x sin(1/x) for x between +/-1. I split the graph into two halves to avoid the singularity at the origin, and I was able to plot the right half but not the left half.

Thanks for your help!

I am producing the following output: As you can see, the two tcolorbox are not the same height, because of the footnote text. If I cut off everything from 'aliqua' onwards, the two boxes would now appear to have the same height, giving a harmonious side-by-side look. If it was just one page, I could adjust the chart height (height=7.2cm) to achieve this. In this particular case, reducing it to height=6.9cm would do the trick. However, I am programmatically generating these pages and therefore need it to be automated. Is there a way I can set a dynamic chart height, which increases or decreases such that the two minipages always have the same height?

Setup I'm following the answer about parameterized curves in a sphere from https://tex.stackexchange.com/a/199715/7561. I'm inserting these spheres in a bigger diagram and noticed the extra space around the axis plots. I was under the impression that hide axis inside the axis environment should remove all the extra white space around the ticks and axis labels, but it doesn't seem the case. See the extra space in the output image below. Question What am I doing wrong? I think that the culprit may be the disabledatascaling which I still need if I want to insert the spheres and their plots next to another nodes, don't I?

I've just started familiarizing myself with tikz, and I've only sticked to 2D shapes. Now, I need to draw the following photo in LaTeX: Not like an exact replica of course, but the same idea. Doing this with 2D coordinates would be a pain, and I know you can work with packages and stuff that just allows you to define shapes based on 3D coordinates, and the package does the rest. But I don't know what package this is, and how to use it. What is the simplest way for me to draw cuboids in LaTeX?

I would like to draw something like this using tikz: So far, I only managed this: using the following code: \documentclass[tikz]{standalone} %\usetikzlibrary{decorations} \usetikzlibrary{decorations.pathmorphing} \begin{document} \begin{tikzpicture} \draw[thick,decoration={aspect=0.3, segment length=3mm,amplitude=1cm,coil},decorate] (0,3) -- (0,0.15); \draw[thick] plot[smooth , tension=2] coordinates {(0,3) (-2.5,1.5) (0,0.15)}; \end{tikzpicture} \end{document} Is there a simple way to add the white gaps so that the coil looks three dimensional? Thanks in advance for your help!

Hello great Tex experts. I want to draw the following plot(from desmos) which is a cylinder, a plane and their intersection. And here is my code: \begin{tikzpicture} \begin{axis}[ view={47}{47}, axis lines=center, xlabel={$x$}, ylabel={$y$}, zlabel={$z$}, xmin=-3, xmax=3, ymin=-3, ymax=3, zmin=-2, zmax=6, legend style={font=\scriptsize}, axis line style={gray!50!black}, tick style={gray!50!black}, tick label style={gray!50!black}, label style={font=\tiny,color=gray!50}, set layers ] % plane \addplot3[surf, % domain=-2:2, domain y=-2:2, opacity=1, colormap/gray,fill=violet] {4 - x}; \addlegendentry{$z+x=4$} % cylinder \addplot3[surf, % domain y=-2:6, domain=0:360, opacity=0.5, colormap/greenyellow,fill=yellow!70] ({sqrt(2)*cos(x)}, {sqrt(2)*sin(x)}, {y}); \addlegendentry{$x^2+y^2=2$} % ellipse \addplot3[thick, blue, domain=0:360,smooth] ({sqrt(2)*cos(x)}, {sqrt(2)*sin(x)}, {4-sqrt(2)*cos(x)}); \addlegendentry{$f(t)$} \end{axis} \end{tikzpicture} And the result: Notice the lower part (below the ellipse) of the cylinder is drawn which is the problem. How to fix that? Also if I reorder the plot commands to draw the cylinder, then plane, then the result will have the plane only (cylinder won't be drawn). Thank you for your time and consideration.

Is there is any general command to put a border around any "figure" (pictures, tables, tikz diagrams). In my case I have a document which uses some images and diagrams made using the circuitikz package. I would like to enclose both of them in borders. I have referred to this post which mentions \frame{\includegraphics{image}} but this seems to work only for image files. I was looking for something more general which can be applied to anything that can be considered a figure ie anything that can wrapped in an environment (figure, table, circuitiz, etc). Does such a thing exist ? And if it does, would it be possible to control the thickness of the border ?

I was wondering if there is an easy way to plot a mesh diagram of a surface and also its normal vector field? For example: I wish to plot the sphere $x^2 + y^2 + z^2 = 1$ and the normal vector field at will be all vectors joining (x,y,z) to (2x,2y,2z), where (x,y,z),lies on the sphere.tiks

I am trying draw a circle is intersection of a plane has equation 2 x − 2 y + z − 15 = 0 and the equation of the sphere is ( x − 1)^2 + ( y + 1)^ 2 + ( z − 2)^ 2 − 25 = 0. The plane cut the sphere is a circle with centre (3,-3,3 and radius r = 4. I can't draw the circle. I tried \documentclass[12pt,border = 2 mm]{standalone} \usepackage{tikz} \usepackage{tikz-3dplot} \usetikzlibrary{arrows,calc,backgrounds} \begin{document} \tdplotsetmaincoords{60}{110} \begin{tikzpicture}[tdplot_main_coords] \path coordinate (T) at (3,-3,3) coordinate (I) at (1,-1,2); \foreach \v/\position in {T/above,I/below} { \draw[fill=black] (\v) circle (0.7pt) node [\position=0.2mm] {$\v$}; } \draw[dashed] (T) circle[radius={4}]; \begin{scope}[tdplot_screen_coords, on background layer] \pgfmathsetmacro{\R}{5}% \fill[ball color=purple, opacity=1.0] (I) circle (\R); \end{scope} \end{tikzpicture} \end{document} How can I draw the circle?

I would like to add regression results to a beamer presentation, since it's a vector autoregressive model there are a lot of coefficients. Therefore, I would like to show the whole table just to give an idea on the dimensions and the lags used in the analysis but then I would like to only highlight certain parts of the table, i.e. certain coefficients. There is the possibility to use framezoom, but this does have the disadvantage, that it does more than zooming in on the box, but shows all that fits on the slide, which again clutters the resulting highligh slide. I can fix that by always creating zoomed areas in the same aspect ratio as my presentation, but that's not really satisfactory. Please see beamer framezoom: restrict zoomed frame to border for a description of this problem. Therefore, I would like to know if there's another tool as flexible as tikz and spy to highlight not a certain part of a picture, but of a table. Zooming in and highlighting part of picture MWE showing the usage of framezoom, which should be replace with tikz. % !TeX spellcheck = en_US \documentclass[13pt ,aspectratio=43 %,handout ]{beamer} \usepackage[english]{babel} \usepackage[utf8]{inputenc} \usepackage{amsmath,amsfonts,amssymb} \usepackage{gensymb} \usepackage{color} \usepackage{lmodern} %\renewcommand{\rmdefault}{lmss} \usepackage{hyperref} %Remove indentation in footnotes %\usepackage[hang,flushmargin]{footmisc} %Table Packages \usepackage{tabularx} \usepackage{longtable,booktabs,tabu} \usepackage{makecell} \usepackage[detect-all]{siunitx} \sisetup{input-symbols = ()} % "(" and ")" are ordinary inputs \usepackage{setspace} \def\V#1,#2/#3/{\Entry[#3]{#1}{#2}} \usepackage{siunitx} %align numbers by decimal point \usepackage{csquotes} % Options for captions \usepackage[hypcap,format = plain, justification=raggedright, singlelinecheck=off]{caption} \captionsetup[table]{belowskip=0em,aboveskip=2pt} \captionsetup[figure]{belowskip=0em,aboveskip=2pt} \usepackage{textcomp,ragged2e} \usepackage{appendixnumberbeamer} %Turn on and of the display of the notes by commenting out the following line %\setbeameroption{show notes} \setbeamertemplate{note page}[plain] \usepackage{tikz} \usepackage{pgfplots} \usetikzlibrary{positioning} % % % Theme %\usetheme{Frankfurt} \usetheme[titleformat = regular , sectionpage = progressbar , subsectionpage = none , numbering = counter %none,counter, fraction , progressbar = foot % none, head, frametitle, foot ]{metropolis} \usepackage{standalone} \usepackage{tikz} % % % % % % % % % % % % % % % % % % % % % % % % % % % % % % \begin{document} \setstretch{1,5} \begin{frame}[shrink = 0.2] \frametitle{Distribution of Leverage prior to Price Decline in 2008 and 2014} \framezoom<1><2>[border](2.5cm,1.5cm)(3cm,2cm) \begin{table}[htb] \footnotesize \begin{center} \begin{tabularx}{\textwidth}{>{\centering}p{0.19\textwidth} >{\centering}p{0.01em} >{\centering}X S[table-format=6.0 ,round-mode=places ,round-precision=0 ,table-align-text-post = false ] S[table-format=6.0 ,round-mode=places ,round-precision=0 ,table-align-text-post = false ] >{\centering}p{0.01em} >{\centering}X S[table-format=6.0 ,round-mode=places ,round-precision=0 ,table-align-text-post = false ] S[table-format=6.0 ,round-mode=places ,round-precision=0 ,table-align-text-post = false ] } \toprule Leverage Percentile & & \multicolumn{4}{c}{2008~Q2} & \multicolumn{3}{c}{2014~Q3} \tabularnewline \cmidrule{3-5} \cmidrule{7-9} & & No. & {Assets} & {Debt} & & No. & {Assets} & {Debt}\tabularnewline \cmidrule{1-1} \cmidrule{3-5} \cmidrule{7-9} $1^{st} Quartile$ & & 33 & 3094.25 & 493.08 & & 33 & 5871.65 & 948.29 \tabularnewline % $0 < P_{0.25} \leq 0.25$ $2^{nd} Quartile$ & & 36 & 11868.81 & 2494.08 & & 36 & 12894.65 & 2749.38 \tabularnewline % $0.25 < P_{0.50} \leq 0.50$ $3^{rd} Quartile$ & & 35 & 5018.03 & 1380.06 & & 36 & 4279.47 & 1328.07 \tabularnewline % $0.50 < P_{0.75} \leq 0.75$ $4^{th} Quartile$ & & 35 & 2844.71 & 1208.22 & & 36 & 2001.95 & 884.75 \tabularnewline % $0.75 < P_{1} \leq 1$ Non-calculable Leverage & & 5 & 1172.49 & 338.66 & & 7 & 1304.48 & 390.58 \tabularnewline \bottomrule \end{tabularx} \captionof{table}{Comparison of the number of companies for each leverage group prior to price declines in 2008~Q2 and 2014~Q3 and their average value of total assets and debt in million US-Dollar.}\label{t.Leverage.Groups} \end{center} \end{table} \end{frame} \end{document}

I would like to create a wiki (several authors) with scientific content, including text, equations, graphs and schemes. I wish to use LaTeX macros (including my own ones) and draw graphics with the powerful PGF/Tikz syntax. My aim is to minimize the work to turn a .tex file into a wiki page, and to keep code flexibility (ideal case would be to copy/paste raw .tex file content in a wiki page and the server should render it). Is Mediawiki able to do that? Is it possible to approach similar behavior with latex2html? Any feedback would be welcome! Thanks
