I am trying to split a table into four equal parts using the select equal part entry of option, as described in the pgfplotstable manual (p. 43). However, the remaining are not distributed evenly among the first columns. Since the table has 39 rows, I would expect only one empty cell overall, but instead I get several empty cells in the last columns. Is this the unexpected behavior, or am I misunderstanding how select equal part entry of works? Here is a minimal working example: \documentclass{article} \usepackage{tikz} \usepackage{pgfplots, pgfplotstable} \pgfplotsset{compat=1.18} \pgfplotstableread{ alpha I DeltaAlpha DeltaI 0 77 0.71 0.5 5 71 0.71 0.5 10 65 0.71 0.5 15 58 0.71 0.5 20 49.5 0.71 0.5 25 40.5 0.71 0.5 30 33 0.71 0.5 35 25 0.71 0.5 40 19 0.71 0.5 45 13 0.71 0.5 50 9 0.71 0.5 55 6 0.71 0.5 60 4 0.71 0.5 65 3 0.71 0.5 70 3 0.71 0.5 75 3 0.71 0.5 80 4.5 0.71 0.5 85 7 0.71 0.5 90 11 0.71 0.5 95 16 0.71 0.5 100 22 0.71 0.5 105 29 0.71 0.5 110 36 0.71 0.5 115 43 0.71 0.5 120 51 0.71 0.5 125 56.5 0.71 0.5 130 63 0.71 0.5 135 68 0.71 0.5 140 72.5 0.71 0.5 145 76 0.71 0.5 150 78 0.71 0.5 155 80 0.71 0.5 160 80 0.71 0.5 165 80 0.71 0.5 170 79 0.71 0.5 175 76.5 0.71 0.5 180 72.5 0.71 0.5 185 67.5 0.71 0.5 190 61 0.71 0.5 }{\NikolPris} \begin{document} \pgfplotstabletypeset[ fixed, fixed zerofill, precision=1, % columns={alpha, I,alpha, I,alpha, I,alpha, I}, display columns/0/.style={select equal part entry of={0}{4}, column name={$\alpha,^\circ$}}, display columns/1/.style={select equal part entry of={0}{4}, column name={$I$}}, display columns/2/.style={select equal part entry of={1}{4}, column name={$\alpha,^\circ$}}, display columns/3/.style={select equal part entry of={1}{4}, column name={$I$}}, display columns/4/.style={select equal part entry of={2}{4}, column name={$\alpha,^\circ$}}, display columns/5/.style={select equal part entry of={2}{4}, column name={$I$}}, display columns/6/.style={select equal part entry of={3}{4}, column name={$\alpha,^\circ$}}, display columns/7/.style={select equal part entry of={3}{4}, column name={$I$}}, ]{\NikolPris} \end{document}

I've created multiple vector graphics for my thesis, exported from the vector program as PDF with embedded ICC color profile (FOGRA39). It appears that every file carries this profile and causes my final thesis PDF to be ~50% color profiles. From my understanding, I cannot not include the ICC color profile in every vector graphic, as this would otherwise default to the publisher's default settings (possibly not FOGRA39). Is there a way in LaTeX to include the PDFs but ensure that the ICC profile is not duplicated in the final PDF? I also have some sRGB images that I do not want to convert to CYMK myself, this should ideally be done by the publisher for best results. Assuming I use pdfx to set the default profile of my PDF/X to FOGRA39, will embedded pictures in sRGB maintain that profile or be somehow converted?

Using tikzposter, if I create 2 blocks in a column environment, and put inside of each the same picture, I obtain block of different size. I would like both blocks to have the same size, given they should have the same content. Minimal example: \documentclass[25pt,a1paper]{tikzposter} \begin{document} \begin{columns} \column{0.45} \block[]{AAA}{ \begin{tikzfigure}[] \includegraphics[width=0.8\colwidth]{Figure/2026-05-05_17-53.png} \end{tikzfigure} } \column{0.45} \block[]{AAA}{ \begin{tikzfigure}[] \includegraphics[width=0.8\colwidth]{Figure/2026-05-05_17-53.png} \end{tikzfigure} } \end{columns} \end{document} With the results below: I have tried to create more than two columns, and the behaviour was strange (this was done with 4 columns of size 0.22, and 2 pictures per block). The first block has a different size than the next four, and the the final three have again a different size.

I am trying to understand how TikZ calculates the position of a node when using the pos option on a rectangle path. Here is a minimal example: \documentclass[border=10pt]{standalone} \usepackage{tikz} \begin{document} \begin{tikzpicture} \draw[thin, gray!25] (0,0)--(4,4); \foreach \p in {0.1, 0.3, 0.5, 0.7, 0.9} { \draw (0,0) rectangle (4,4) node[pos=\p, black] {\p}; } \end{tikzpicture} \end{document} From my experiments, it seems that the position is determined along the diagonal of the rectangle rather than along its perimeter. How exactly is pos computed for a rectangle path? Is there a general rule for how pos is defined for different path constructions in TikZ? I checked the TikZ/PGF manual, but the manual doesn’t seem to explain how pos works specifically for the rectangle case.

In attempting to draw three planes using tikzpicture and addplot3s, I'm encountering the following issue: when adding the a third steep plane, the z axis is rescaled, visually changing the angle between the existing planes. How can I keep the steep plane without causing the z axis to be rescaled? Here is a working code and corresponding picture of three planes, none of which is too steep: \documentclass[border=5pt]{standalone} \usepackage{pgfplots} \pgfplotsset{compat=1.18} \begin{document} % \begin{center} \begin{tikzpicture} \begin{axis}[ width=7cm, height=5.8cm, view={55}{28}, axis lines=center, axis on top=true, axis line style={dashed, gray, thick}, xlabel={$x$}, ylabel={$y$}, zlabel={$z$}, domain=-2:2, y domain=-2:2, samples=28, samples y=28, xtick=\empty, ytick=\empty, ztick=\empty, colormap={blueplane}{ rgb255=(40,90,160) rgb255=(90,140,210) rgb255=(160,200,240) }, colormap={yellowplane}{ rgb255=(230,210,70) rgb255=(245,230,100) rgb255=(255,245,160) }, colormap={greenplane}{ rgb255=(60,130,90) rgb255=(110,180,130) rgb255=(180,230,190) }, point meta min=0, point meta max=1, ] \addplot3[ surf, shader=interp, opacity=1, colormap name=yellowplane, point meta={0.5 + 0.3*z} ] {0.00*x}; \addplot3[ surf, shader=interp, opacity=1, colormap name=blueplane, point meta={0.5 + 0.3*z} ] {-0.3*x}; \addplot3[ surf, shader=interp, opacity=0.8, colormap name=greenplane, point meta={0.5 + 0.1*y} ] {0.10*y}; \end{axis} \end{tikzpicture} %\end{center} \end{document} [![enter image description here][1]][1] Here is a problematic code and corresponding picture, where I have only changed the green plane from {0.10*y} to {0.90*y}, making it rather steep and causing the z axis to be rescaled: \documentclass[border=5pt]{standalone} \usepackage{pgfplots} \pgfplotsset{compat=1.18} \begin{document} %\begin{center} \begin{tikzpicture} \begin{axis}[ width=7cm, height=5.8cm, view={55}{28}, axis lines=center, axis on top=true, axis line style={dashed, gray, thick}, xlabel={$x$}, ylabel={$y$}, zlabel={$z$}, domain=-2:2, y domain=-2:2, samples=28, samples y=28, xtick=\empty, ytick=\empty, ztick=\empty, colormap={blueplane}{ rgb255=(40,90,160) rgb255=(90,140,210) rgb255=(160,200,240) }, colormap={yellowplane}{ rgb255=(230,210,70) rgb255=(245,230,100) rgb255=(255,245,160) }, colormap={greenplane}{ rgb255=(60,130,90) rgb255=(110,180,130) rgb255=(180,230,190) }, point meta min=0, point meta max=1, ] % x < 0: blue is above yellow % Draw yellow first, then blue \addplot3[ surf, shader=interp, opacity=1, colormap name=yellowplane, domain=-2:0, y domain=-2:2, point meta={0.5 + 0.3*z} ] {0.00*x}; \addplot3[ surf, shader=interp, opacity=1, colormap name=blueplane, domain=-2:0, y domain=-2:2, point meta={0.5 + 0.3*z} ] {-0.3*x}; % x > 0: yellow is above blue % Draw blue first, then yellow \addplot3[ surf, shader=interp, opacity=1, colormap name=blueplane, domain=0:2, y domain=-2:2, point meta={0.5 + 0.3*z} ] {-0.3*x}; \addplot3[ surf, shader=interp, opacity=1, colormap name=yellowplane, domain=0:2, y domain=-2:2, point meta={0.5 + 0.3*z} ] {0.00*x}; % Green plane: y = 0 \addplot3[ surf, shader=interp, opacity=0.8, colormap name=greenplane, domain=-2:2, y domain=-2:2, samples=22, samples y=22, point meta={0.5 + 0.1*y} ] {0.90*y}; \end{axis} \end{tikzpicture} % \end{center} \end{document} [![enter image description here][2]][2] [1]: https://i.sstatic.net/3yfLU2lD.png [2]: https://i.sstatic.net/bVjYARUr.png

In LateX, there are many ways to have the bibliography distributed into different sections depending on the nature of the references cited, eg. “Primary Sources” for ancient authors and “Secondary Sources” for modern authors. An example follows: \begin{filecontents}{\jobname.bib} @Article{Dols1987, author = {Dols, Michael W.}, date = 1987, journaltitle = {Bulletin of the History of Medicine}, entrysubtype = {secondary}, langid = {english}, pages = {367--390}, title = {The Origins of the Islamic Hospital: Myth and Reality}, volume = 61, } @Inbook{endress1992, author = {Endress, Gerhard}, editor = {Fisher, Wolfdietrich}, location = {Wiesbaden}, entrysubtype = {secondary}, publisher = {Reichert}, booktitle = {Grundriß der arabischen Philologie}, date = 1992, langid = {german}, note = {Supplement}, pages = {3--152}, title = {Die Wissenschaftliche Literatur}, volume = 3, } @Mvbook{al-nadim, author = {{Ibn an-Nadīm}}, editor = {Flügel, Gustav}, location = {Leipzig}, entrysubtype = {primary}, date = {1871/1872}, entrysubtype = {primary}, shorthand = {{Ibn an-Nadīm}, \mkbibemph{{Fihrist}}}, title = {{Fihrist}}, volumes = 2, } @Book{al-qifti, author = {{Ibn al-Qifṭī}}, editor = {Lippert, Julius}, location = {Leipzig}, entrysubtype = {primary}, date = 1903, entrysubtype = {primary}, shorthand = {{al-Qifṭī}, \mkbibemph{{Taʾrīḫ}}}, title = {{Taʾrīḫ al-ḥukamāʾ}}, } \end{filecontents} \documentclass[a4paper,12pt]{article} \usepackage[style=oxnotes]{biblatex} \addbibresource{\jobname.bib} \begin{document} This file illustrates how such a field as \verb|entrysubtype| can be used to have the bibliography distributed into two different sections, namely ``primary sources'' for ancient authors and ``secondary sources'' for modern literature (commentaries, books, articles, chapters and the like). For example the two references that follow are taken from modern authors: one\footcite{Dols1987} and two.\footcite{endress1992} Whereas these other two are taken from ancient authors: one\footcite{al-nadim} and two.\footcite{al-qifti} \printbibliography[title={Primary Sources}, subtype=primary] \printbibliography[title={Secondary Sources}, subtype=secondary] \end{document} My question: how can the same be achieved with OpTeX? A way would be to use a dedicated BibTeX field as entrysubtype. Right now, OpTeX can do the sorting based on sortedby, but without inserting, of course, the headings. It would be great to have an option that would allow for multiple lists in OpTeX!

I'm trying to use the exercise package to collect solutions and then print them later. This is mostly working, but if I have answers typeset in a separate file and included into a main file, any labels introduced within the answers of that separate file cannot be referenced. In case it's relevant, if I input the file instead of include it, the reference is correctly resolved. Here's a MWE. In the main file, we have \documentclass{article} \usepackage[lastexercise,answerdelayed]{exercise} \begin{document} \include{extra} \begin{Exercise} \Question This is a second question. \end{Exercise} \begin{Answer} \Question \begin{equation}\label{eq:test2} x^2 \end{equation} Have a look at (\ref{eq:test2}). \end{Answer} Answers go here \shipoutAnswer \end{document} A second file, extra.tex contains the following: \begin{Exercise} \Question This is a question. \end{Exercise} \begin{Answer} \Question \begin{equation}\label{eq:test} x^2 \end{equation} Have a look at (\ref{eq:test}) \end{Answer} So, we have 2 questions + answers that are essentially the same. The answers are both typeset after the "Answers go here" text. The reference to eq:test2 works, the reference to eq:test does not work. How can I fix this?

I have an article formatted using the LIPIcs stylesheet. By defaut, LIPIcs shows a placeholder DOI information in the PDF: Digital Object Identifier 10.4230/LIPIcs... I would like to remove this, to post the article to arXiv without DOI information but keeping the rest of the LIPIcs formatting. How can I achieve this? One option is to use \hideLIPIcs but this also hides other information, e.g., the Creative Commons licensing.

Problem with biber. I am using TeXShop on a Mac machine. When compiling with TeXShop a simple sample document like this test.tex (MWE): \documentclass[12pt]{book} \usepackage{polyglossia} \usepackage[backend=biber, style=authortitle-ibid]{biblatex} \addbibresource{biblio.bib} \begin{document} \mainmatter \cite{test} \backmatter \printbibliography[heading=bibintoc] \end{document} I don't get the Bibliography printed and the citations are not cited.

I am trying to draw a simple closed loop using circuitikz. I noticed that using -- cycle does not work here (as shown in the figure on the right). Here is a minimal example: \documentclass[border=10pt]{standalone} \usepackage[american]{circuitikzgit} \begin{document} \begin{circuitikz}[line width=2pt] \draw (0,0) to[isource] (0,3) -- (2,3) to[R] (2,0) -- (0,0); \end{circuitikz} \begin{circuitikz}[line width=2pt] \draw (0,0) to[isource] (0,3) -- (2,3) to[R] (2,0) -- cycle; \end{circuitikz} \end{document} Note that I used a thick line width only to make the issue more visible with manually closing the loop. Why does -- cycle not work properly here, and what is the correct way to fix this?

I have a .tex of a paper I am writing, and it must be done in the journal's custom .cls. They even provide a sample folder, with a "Sample.tex" using their custom ".cls". Even though they are in the same folder, however, TeXStudio keeps throwing an error stating that the .cls file cannot be found. Based on the log when I hover over the document class (which TeXStudio flags in green), it seems like it is searching the base document classes, instead of looking in the same folder. Even when I use the complete file path instead of just the name of the file, it still throws an error. Something similar is happening with the ".eps" which represent the image files. What can I do to make it so TeXStudio properly searches the file in the correct directory (namely, the one containing the .tex)? Thanks in advance!

For one of my statistics projects I need to calculate some confidence intervals. I put them all in a table, but it bothers me that the square brackets are not lining up. Is there a way to make it so that all of them line up at the beginning and at the end? I added a MWE and a picture. \documentclass[11pt]{article} \usepackage{amsmath} \usepackage{graphicx} \usepackage{booktabs} \usepackage{float} \usepackage[margin=2.5cm]{geometry} \begin{document} \begin{table}[h] \centering \begin{tabular}{lccc} \toprule Variable & Confidence interval mean & Confidence interval median & Confidence interval variance \\ \midrule BMI & $[27.31,29.02]$ & $[26.52,28.06]$ & $[37.53,54.90]$ \\ WHR & $[0.86,0.88]$ & $[0.86,0.89]$ & $[0.004,0.006]$ \\ MAP & $[99.06,102.86]$ & $[97.33,101.33]$ & $[183.93,282.34]$\\ CHR & $[4.08,4.45]$ & $[3.70,4.25]$ & $[1.71,2.61]$ \\ Age & $[42.19,46.09]$ & $[40.00,45.00]$ & $[206.73,287.33]$ \\ Stab\_glu & $[89.34,95.99]$ & $[85.00,89.00]$ & $[283.18,1405.86]$ \\ Glyhb & $[4.69,4.87]$ & $[4.62,4.79]$ & $[0.43,0.64]$ \\ \bottomrule \end{tabular} \caption{Confidence intervals for diabetic negative data} \label{tab:CI diabetic negative} \end{table} \end{document}

A question similar to Capitalize French part name. What I wish : I would like the headers to be written uppercase : on even pages : CHAPITRE X. TITLE OF THE CHAPTER on odd pages : PREMIÈRE PARTIE. TITLE OF THE PART What I tried : I used the fancyhdr package and here is a minimal working example : \documentclass[twoside]{book} \usepackage[french]{babel} \usepackage[T1]{fontenc} \usepackage{fancyhdr} \usepackage{lipsum} % Defining command \parttitle \newcommand*\parttitle{} \let\origpart\part \renewcommand*{\part}[2][]{% \ifx\\#1\\% argument optionnel absent ? \origpart{#2}% \renewcommand*\parttitle{#2}% \else \origpart[#1]{#2}% \renewcommand*\parttitle{#1}% \fi } % Defining command \chaptertitle \newcommand*\chaptertitle{} \let\origchapter\chapter \renewcommand*{\chapter}[2][]{% \ifx\\#1\\% argument optionnel absent ? \origchapter{#2}% \renewcommand*\chaptertitle{#2}% \else \origchapter[#1]{#2}% \renewcommand*\chaptertitle{#1}% \fi } %Defining right and left marks \renewcommand{\leftmark}{\MakeUppercase{\chaptername \ \thechapter. \ \chaptertitle}} \renewcommand{\rightmark}{\MakeUppercase{\partname. \ \parttitle}} % Defining header style \pagestyle{fancy} \fancyfoot{} \fancyfoot[C]{\thepage} \fancyhead{} \fancyhead[RO]{\emph{\rightmark}} \fancyhead[LE]{\emph{\leftmark}} \begin{document} \part{Titre de la partie} \chapter{Titre du chapitre} \lipsum[1-10] \end{document} Doing this yields the correct result for even pages (btw it matches the default setting of fancyhdr) : Yet, on odd pages, the part title is written uppercase but not the partname : I would like the "Première partie" to be written uppercase. What I understand so far : With babel in French, part names are by default written as "Première partie", "Deuxième partie", etc. (and not as "Partie 1", "Partie 2", etc.). The doc of the babel french package explains (p.38-39) : \StartBabelCommands*{french}{captions}[unicode, fontenc=TU EU1 EU2, charset=utf8] \SetString{\partnameord}{partie} \SetString{\partfirst}{Première} \SetString{\partsecond}{Deuxième} When PartNameFull=true (default), \part{} is printed in French as “Première partie’’ instead of “Partie I’’. As logic is prohibited inside \SetString, let’s hide the test about PartNameFull in \FB@partname. \SetStringLoop{ordinal#1}{% \frenchpartfirst,\frenchpartsecond,Troisième,Quatrième,% Cinquième,Sixième,Septième,Huitième,Neuvième,Dixième,Onzième,% Douzième,Treizième,Quatorzième,Quinzième,Seizième,% Dix-septième,Dix-huitième,Dix-neuvième,Vingtième} \AfterBabelCommands{% \NewDocumentCommand\FB@emptypart{}{\def\thepart{\unskip}}% \NewDocumentCommand\FB@partname{}{% \ifFBPartNameFull \csname ordinal\romannumeral\value{part}\endcsname\space \partnameord\FB@emptypart \else Partie% \fi}% } \SetString{\partname}{\FB@partname} \EndBabelCommands When setting the babel in another language, the part is expressed as "Parte 1", "Part 1", "Teil 1" and not as "Première partie" as in french-babel. As well, when setting PartNameFull = false, the part is written in French as "Partie 1". In those cases, the command \MakeUppercase{\partname} works well and I get the part name uppercase as wanted. For instance in English : So I guess the issue is in the composition of the part name when PartNameFull = true, but I couldn't figure where the problem is and how to solve it.

How can one create a figure like the following? Here is my attempt. I use the plot function with a combination of a parabola (for the general shape) and a sine wave (to create the "wiggles"). \documentclass[tikz,border=10pt]{standalone} \usepackage{amsmath} \begin{document} \begin{tikzpicture}[>=latex] % Draw the wavy boundary % We use a parabola-like base: 0.2*x^2 - 2 % We add a small sine component for the "roughness" \draw[thick] plot [domain=-3.2:3.2, samples=100, smooth] (\x, {0.2*\x*\x - 2 + 0.08*sin(600*\x)}); % Draw Horizontal Axis (x, u) \draw[->] (-3.5,0) -- (3.5,0) node[below right] {$x, u$}; % Draw Vertical Axis (y, v) \draw[->] (0,-2.5) -- (0,0.8) node[right] {$y, v$}; % Origin label \node[below left] at (0,0) {$0$}; \end{tikzpicture} \end{document} My problem is that the boundary appears too 'wavy'. Also there is a small unecessary part above the x-axis. Any ideas to improve the figure?

What is the best way of coding arrows from one letter to another to demonstrate the FOIL method? (This example was made in Word)

I want to create a bibliography of works by a single author. Items will be listed chronologically and numbered, say 1--115, with brackets around the numbers as in the thebibliography environment. But each item from 2010, for example, will be listed under the heading 2010 (centered, same font size as the bibliography itself). In case I'm not being clear, here is an example, which I hope is not pay-walled. How can I best accomplish this?

Context With the original TeX/LaTeX and also with pdflatex you could make fonts heavier depending on output device via METAFONT. This, and that most printers would “bleed” more than typically today, imply that the Computer Modern fonts that are used in these setups by default (if OT1 font encoding) are generally designed “too thin” (in fact, they had to be for METAFONT to do its thing), their outlines are thinner than what would have been desired as final output… This has never been changed in subsequent successors to the original Computer Modern fonts over decades (except partially recently in the New Computer Modern Roman book font at the limited set of sizes it supports compared to Latin Modern). If you are not using METAFONT to make fonts heavier, then the results with lualatex using Latin Modern by default are very similar, and you can stop reading here. If, however, you miss the unique beauty of Computer Modern, but have to migrate to lualatex (for accessible tagged pdfs or any other features), here is first a concrete example as the question and then an answer by me. It took me half a year to find something reasonably useful that did not involve changing TeX-related source code or TeX fonts, a process that included several questions here (thanks for all the answers!) and also recently quite a few sessions with Google's Gemini AI, who proved to be very helpful in the end due to its broad knowhow and openness to share that. Concrete Example I am using pdflatex with OT1 font encoding which implies that it uses the Computer Modern (CM) font family by default, in my case I am specifically using Computer Modern Sans (plus is implicitly using some symbol fonts from Computer Modern). My basic setup is that I added the following mode to modes.mf (which is the same as the standard lexmarkr with just the blacker value slightly changed): mode_def xphi = mode_param (pixels_per_inch, 1200); mode_param (blacker, 1.9); % only difference to 'lexmarkr' (2 there) mode_param (fillin, 0); mode_param (o_correction, 1); mode_common_setup_; enddef; And in my latex sources I am using these settings: % !TEX TS-program = pdflatex \pdfpkresolution=1200 \pdfpkmode={xphi} \pdfmapfile{} \textwidth=85.5mm % OT1 is the default unless you are creating a tagged pdf % (which is not well supported on pdflatex anyway) %\usepackage[OT1]{fontenc} Actually, I use two text widths, one for rendered images on my website (the one above) and a larger one for US Letter sized articles. For completeness: I am rendering the images with GraphicsMagick (similar to ImageMagick, but outperformed it in my use cases): gm convert -density 600 "$NAME.pdf" \ -flatten -trim -blur 2.6 -resize 50% +repage -density 72 \ -strip -quality 50% $NAME.jpg For the full source code of my website see https://github.com/exactphilosophy-net/exactphilosophy.net (and there maybe first the source/def*.tex files). And this is a sample result, the look and feel I want to achieve also with lualatex… I will answer what I managed to do in a sec, but, of course, better solutions are always welcome—now and later!

I am currently writing a report on the Traveling Salesman Problem (TSP), and I would like to include an interactive visualization directly in my final PDF. My goal is to have a slider (or a set of buttons) that allows the reader to change the number of vertices $n$ (e.g., from 3 to 6). When the slider is moved, I want the PDF to dynamically update: A TikZ drawing of a complete graph $K_n$. A text node displaying the calculated number of edges: $|E| = \frac{n(n-1)}{2}$. I have looked into packages like animate, media9, and the possibility of embedding JavaScript via insdljs, but I am unsure which approach is the most modern, robust, and compatible with standard PDF readers (like Adobe Acrobat or web-based viewers). Here is a static Minimum Working Example (MWE) of the graph I am trying to make dynamic: \documentclass{article} \usepackage{tikz} \begin{document} % I want 'n' to be controlled by a slider in the PDF \def\n{5} \begin{center} \begin{tikzpicture}[scale=0.8] % Draw edges \foreach \i in {1,...,\n} { \foreach \j in {1,...,\n} { \ifnum\i<\j \draw[blue!40, line width=0.5pt] ({90+(\i-1)*360/\n}:1.5cm) -- ({90+(\j-1)*360/\n}:1.5cm); \fi } } % Draw vertices \foreach \i in {1,...,\n} { \node[circle, fill=blue, draw=white, inner sep=2pt, label={[font=\tiny, color=blue]{90+(\i-1)*360/\n}:$v_{\i}$}] at ({90+(\i-1)*360/\n}:1.5cm) {}; } \end{tikzpicture} \vspace{0.5cm} % I want this text to update when the slider moves Number of vertices: $n = \n$ \\ Number of edges: $|E| = \pgfmathparse{\n*(\n-1)/2}\pgfmathprintnumber{\pgfmathresult}$ \end{center} \end{document} Is there a pure LaTeX/TikZ way (perhaps with animate) to step through these values using interactive buttons?
