Recently on X, I saw an Andrews plot and decided to plot it in LaTeX. MATLABもStatistics and Machine Learning Toolboxも持っていないので、私はLaTeXで Fisher Iris Dataset の Andrews plot を描いています https://t.co/eKnGAvWpLL pic.twitter.com/1tXy5BxrfK — LaTeX.org (@TeXgallery) May 7, 2026 I took the data file iris.csv from GitHub , and this is my code: \documentclass[border=10pt]{standalone} \usepackage{pgfplots}…
The third edition of the LaTeX Beginner’s Guide is now available with 30% off at Amazon, and is ranked as the #1 new release in Amazon’s Technical Writing category. Grab it as long as the Big Spring Sale runs!
The third, improved, and extended edition of the LaTeX Beginner’s Guide was published this month, March 2026. Compared to the first edition from 2011 and the second edition from 2021, the book has been thoroughly revised. The code examples were updated to work with current LaTeX classes and packages as used in 2026, so everything compiles smoothly with modern distributions. This edition also adds…
In November 2024, a translation of the TikZ book written by Stefan Kottwitz has been released by Asakura Publishing. 2024年11月に、Stefan Kottwitz著のTikZに関する書籍の翻訳版が朝倉書店から発売されました。LaTeXで画像を作るための実用的な入門書。TikZにより数学、科学、技術論文に図や画像を簡単に入れられる。アイデアやデータを可視化してプロフェッショナルな図表やプロットを2次元でも3次元でも表示できるようになるために。 本書の内容 第1章 「TikZで始める」…

From mathcurve.com : Alain s curve (studied by Alain Juhel) is the projection of the intersection of the elliptical cone c²z²=a²x²-b²y² with the hyperbolic paraboloid cz=x²-y² onto the xy plane: So it makes sense to plot that xy projection as 0-level contour plot of a 3D surface. The equation (x² y²)² = a²*x² + b²*y² means plotting the zero level of f(x,y,a,b) = (x² y²)² = a²*x² + b²*y². Here s a…
Inspired by Juan Carlos on X: #mathart #parametric #surfaces https://t.co/kY3gJxHvd1 pic.twitter.com/GbZ16Yyw5U — ∞ 𝕁uan ℂarlos (@jcponcemath) April 21, 2025 A Breather surface is beautiful, a pseudosphere famous in differential geometry and theoretical physics. A parametrization is here . I plotted it with pgfplots and TikZ in LaTeX, and colored it like a flower, using the colormaps…
On X (Twitter), Juan Carlos aka @jcponcemath posts math content frequently. I saw hist post about the Aizawa attractor , a spherical-shaped attractor made from 6 parameters (a, b, , f). Three equations generate a trajectory from an initial point. I plotted the motion trajectories with Lua and pgfplots based on Juan Montijano, Mario Pérez, Luis Rández, and Juan Luis Varona, Numerical methods with…
I saw a beautiful parametric plot on X (Twitter) by Juan Carlos , that looks like a rose, done in Desmos .

I'll plot the rose in LaTeX with TikZ on Valentine's day next week! — LaTeX.org (@TeXgallery)…
On X (Twitter), I saw a post by @ThePhysicMemes making fun of a bear running on a jumping ball. I used this occasion to generate periodic plots with an if-condition, demonstrating also how functions can be declared: This LaTeX document shows how to use the modulo operation together with an if-then-else statement to generate periodic functions with a TikZ function declaration. We apply it to get a…
Mathieu aka @miniapeur posted another meme on X (Twitter). It contained a 3D plot of a wavy function. So I did a similar plot, but for roundness and rotational symmetry parametrized it differently so it won t have these edgy corners. For a function with rotation symmetry, using polar coordinates gives us smooth edges. We have a custom colormap for a blue gradient, and sorted depth buffering, with…
I saw Gabriel s Horn on X (Twitter) posted by @sonukg4india. Looks nice, so let s plot it ourselves. We can use pgfplots to draw Gabriel's horn quickly in LaTeX: pic.twitter.com/aoDjL3vwHw — LaTeX.org (@TeXgallery) February 3, 2025 Some math and a plot in Matlab is also at mathworks.com . \documentclass[border=10pt]{standalone} \usepackage{pgfplots} \pgfplotsset{compat=1.18} \begin{document}…
I saw tomoq s star-shaped plot on X (Twitter), together with a pretty big implicit function definition: How to plot this? An easy way is to consider the left side as a function z=f(x,y) in three dimensions, and that equation would be a contour line at height z=1. So, let s plot it together with contour lines at different heights, to see how they run. Run the files with -enable-write18 or…
