TikZ

I have a main.tex file that includes content with the \subfile command, let's call one of these subfiles sub.tex. All these subfiles generate many Tikz pictures, that i store in external files via the \tikzexternalize command. The goal is to store them to avoid re-compiling them every time when compiling chapters independantly or when compiling the whole project. My issue is the following: when compiling the subfiles independantly, the pictures have a prefix equal to the subfiles' filenames, for example sub for sub.tex. But when compiling main.tex, the compiler tries to load pictures with a prefix of main, which aren't found, thus recreates each picture from each subfile with a prefix of main. I found some posts on this forum to help the main file to retrieve the name of the subfiles (for example with having the subfiles call \tikzsetexternalprefix with a prefix of \jobname or \currfilename), but in my case they all are equal to the main filename. Is there a way to dynamically retrieve the proper name of the subfiles when compiling from the main file, such that these pictures can be loaded properly ?

I'm trying to plot an illustration of the fixed point method in which a function is evaluated repeatedly in a loop. The result should be a staircase or spiral plot on top of the plot of the function itself. I've read here about the use of \edef inside a foreach loop. The following MWE should show what I'm trying to do, but it seems to only perform a single iteration. Notes: the loop variable isn't used inside the loop. perhaps it's an illusion that only single iteration is performed and the real issue is that \xprev and \xnext aren not updated at each pass through the loop. I tried placing the updates inside the \edef, but that gives an undefined control sequence error. I also tried \pgfplotsinvokeforeach instead of \foreach, but only obtained other errors. \documentclass{standalone} \usepackage{tikz} \usepackage{pgfplots} \pgfplotsset{compat=1.18} \begin{document} \pgfmathdeclarefunction{g}{1}{\pgfmathparse{#1^2 - 2}} \begin{tikzpicture} \begin{axis} [ xmin = -2.5, xmax = 2.5, ymin = -3, ymax = 3, axis x line = center, axis y line = center, domain=-2.5:2.5, samples=300, ] \addplot[ultra thick] {g(x)}; % graph of g \addplot[thin] {x}; % diagonal \def\xstart{-0.75} \pgfmathsetmacro{\xprev}{\xstart}; \pgfmathsetmacro{\xnext}{g(\xprev)}; \draw[thick, blue] (\xstart, 0) -- (\xstart, \xnext) -- (\xnext, \xnext); \foreach \i in {1, 2, 3}{ \pgfmathsetmacro{\xprev}{\xnext} \pgfmathsetmacro{\xnext}{g(\xprev)} % x <- g(x) \edef\plotoneiter{% \noexpand% \draw[thick, blue] ({\xprev}, {\xprev}) -- ({\xprev}, {\xnext}) -- ({\xnext}, {\xnext}); }\plotoneiter% } \end{axis} \end{tikzpicture} \end{document} Thanks in advance for any hints!

IMO, the node's contents in deeply inside tikzpicture, which is safely protected by the group intuitively, and only control by tikz option align=<alignment>. My detailed questions are: In case I, without neigther align=center nor outside \centering, why the \\ didn't raise an error with LR-mode? In case II, why outside \centering would affect the node's contents mode?

In the following 4800 pages long topology book one can see lots of images like this: At the moment I am writing a document (Using Lyx) in which I would like to include similar plots. Does anyone know what package is being used here? (ctrl+F -ing the documents makes my whole pc crash) Is this simply Tikz? From my experience (prior question of mine) generating such plots usually involves quite complicated calculations (to get the precise shape you want), so I would also love to get some advice on how to "make some shortcuts" if possible. In the linked book one can find (I would assume) hundreds of such (very complicated) figures, so I am very skeptical that the author "hand tailored" each and every one of them. Thank you!

As I was intent on moving function declarations further up, so as to use them in multiple files, I noticed something unexpected. The first code plots a thin black line. The second code plots thick blue dots. I asked a well-known LLM and got a plausible explanation together with a hallucination. Do you have a suggestion to declare functions higher up while preserving the style? See a motivation further down. Example 1 \documentclass[border=3pt,tikz]{standalone} \usepackage{pgfplots} \pgfplotsset{compat=newest} \tikzset{define functions/.style={% declare function={ A = 1.0; a = 0.5; f(\x) = A*\x^a; }, }, } \begin{document} \begin{tikzpicture} \begin{axis}[ domain=0:100, samples=100, ] \addplot[define functions] {f(x)}; \end{axis} \end{tikzpicture} \end{document} Example 2 \documentclass[border=3pt,tikz]{standalone} \usepackage{pgfplots} \pgfplotsset{compat=newest} \tikzset{define functions/.style={% declare function={ A = 1.0; a = 0.5; f(\x) = A*\x^a; }, }, } \pgfplotsset{ every axis plot/.append style={define functions}, } \begin{document} \begin{tikzpicture} \begin{axis}[ domain=0:100, samples=100, ] % [define functions] not used here \addplot {f(x)}; \end{axis} \end{tikzpicture} \end{document} LLM talking now: Example 1 \addplot[define functions] {f(x)}; You explicitly attach the define functions style only to that plot. No other styles are affected. PGFPlots uses the default plot style, which is a thin black line (black, line width 0.4pt). Example 2 \pgfplotsset{every axis plot/.append style={define functions}} \addplot {f(x)}; You append the define functions style to every plot. But here’s the subtlety: every axis plot applies before the default plot style is applied, and declare function is a key that is not strictly separate from plotting keys. What happens internally: PGFPlots interprets your appended style as including both the function declaration and the style from the first plot in your style list. Because of key expansion order, the default line style is overridden. The plot falls back to the first "unknown" style PGFPlots sees for drawing, which is often the blue mark=* style (used for points), producing thick blue dots. Why this happens every axis plot is applied before \addplot options are merged. declare function is technically a "style key" in the PGFPlots system. PGFPlots sees a style (from every axis plot) that contains no explicit draw key, so it falls back to its default marker style (mark=*, thick, blue). When you attach [define functions] directly to \addplot, the default line style is preserved, so you get a thin black line. How to fix it You need to combine your define functions style with the standard line style: if you want to keep PGFPlots defaults but still append: \pgfplotsset{ every axis plot/.append style={define functions, /pgfplots/line} } Me speaking again: No this doesn't work and nor do the several other suggestions I received. Motivation: I would save different parameter values in distinct files and load them with, say \input{func1.tex}, so I can share code across multiple figures. The syntax used in declare function is natural, unlike an alternative like \pgfmathdeclarefunction{f}{1}{\pgfmathparse{1.0*#1^(0.5)}}. I'm not averse to trying something radically different from my current approach, including using LuaTeX or Python.

I want to include a plot generated by Mathematica within a TikZ picture so that the origin (0,0) of the included plot is exactly at the TikZ origin (0,0). Here's how I create the Mathematica plot: SetOptions[$FrontEndSession, PrintingStyleEnvironment -> "Working"] cm = 72/2.54; parab = Plot[x^2/2, {x, 0, 3}, PlotRange -> {0, 4.5}, Ticks -> None, Axes -> True, AxesOrigin -> {0, 0}, AspectRatio -> Automatic, ImageSize -> 1 -> cm, Epilog -> {Purple, PointSize[Medium], Point[{1, 1/2}], Point[{2, 2}],Point[{3, 9/2}]}] Export["parabola.png", parab] Here is the exported .png (as was requested in a comment): And here is the LaTeX code where the Mathematica-generated graphic is imported and then the result of typesetting that LaTeX code: \documentclass{article} \usepackage{graphicx} \usepackage{tikz} \begin{document} \begin{tikzpicture} \node[anchor= south west] at (0,0) {\includegraphics{parabola.png}}; \draw[dashed] (0,0) grid (4,5); \fill[red] (0,0) circle (0.1); % origin (0,0) from TikZ \end{tikzpicture} \end{document} The LaTeX output: Problem: The origin of the graphic inserted there does not match the origin in the TikZ picture. (This is the case even if I include in the Mathematica Plot command the options ImagePadding -> None, ImageMargins -> 0.) Rather, the graphic exported from Mathematica is shifted a bit upwards and rightwards so that its origin is no longer at the TikZ picture origin. So the question is whether there is some extra space to the left and bottom of the graphic being exported from Mathematica, on the one hand, or whether there is something I don't understand about placement of the import within the TikZ picture. Further information: Following a comment, I directly included the Mathematica-exported .png into a box with: \documentclass{article} \usepackage[top=0.1cm,left=0.1cm]{geometry} \usepackage{graphicx} \usepackage{tikz} \begin{document} \fboxsep=0pt \fbox{\includegraphics{parabola.png}} \end{document} And the result (ta-da!) as a .png (to allow import here) already shows the shifting of the origin (0,0) upwards and to the left of the lower-left corner: [![LaTeX boxed image from Mathematica export][3]][3] (I originally aksed about this in https://mathematica.stackexchange.com/questions/316827/make-graphics-units-exactly-1-cm but the answer proffered there does not resolve the issue.) The cure: in Mathematica! By changing the option Axes -> True to Axes -> None when generating the Mathematica graphic, I discovered that Mathematica is inserting extra space to the left of the y-axis and below the x-axis when those axes are actually drawn. For me, the solution, at least in this case, is to use Axes -> None; then the coordinate origin (0,0) is precisely at the lower-left corner of the graphic exported. Thank you to all those who suggested cures through TikZ or editing the exported graphic! [3]: https://i.sstatic.net/8MSy2nFT.png

I am currently working on a 3D surface plot in which both x-, and y-axis are logarithmic. The issue I am facing and why I am posting is that the measurements are too close to each other, and I hence end up with overlapping axis ticks on the x-, and y-axis. Is there a good way to transform individual ticks, bet it an odd/even selection, or directly picking out individual ticks and then shifting them?

I want to make a quantum circuit (with possibly quantikz) that starts in a maximally entangled state for which each tensor factor is partitioned. That is, I want to replicate some of the quantum circuits as below (from https://arxiv.org/abs/1911.06314, p26): I know quantikz has the command \makeebit[s]{l} (p13), but it seems like it's only possible to use it for the lines connecting Br and Bl on the right hand side, not both and not either side. I am looking for a way to at least replicate the right side of the figure, preferably also the left side and preferably using a package. Is that possible? A satisfactory answer would be: some command like \eebit that generates the drawn line as in the 'desired outcome' some alternative tensor graphing package that does the job I'd greatly appreciate your considerations and thanks in advance.

I'm attempting to recreate the below diagrams using the feynman-tikz package. I've attempted the below code, \begin{subfigure}{0.4\textwidth} \centering \feynmandiagram[layered layout, horizontal = a to b]{ a -- [fermion] d -- [fermion, edge label =$e^-$] c -- [fermion] b, d -- [photon, half left, edge label =$\gamma$] c, }; \caption{An electron emits a photon which is then reabsorbed.} \end{subfigure} \begin{subfigure}{0.4\textwidth} \centering \feynmandiagram[horizontal = a to b]{ a -- [fermion] d -- [fermion, edge label=$e^-$] c -- [fermion] b, d -- [photon, quarter left, edge label=$\gamma$] e -- [fermion, half left=0.5cm, edge label=$e^-$] f -- [fermion, half left=0.1cm, edge label=$e^+$] e, f -- [photon, half left] c, }; \caption{Vacuum polarisation.} \label{fig:polarisation} \end{subfigure} however, my diagram (b) looks less than ideal, as shown below. Is there a way to make the latex diagram look more like the drawn one without having to resort to specifying vertices manually? Thanks.

What is the simplest solution to draw an ellipse with dashes, only each dash has an arrowhead (either clockwise or anticlockwise)? I struggled to create this solution with anti-clockwise arrows. I had to draw the ellipse backwards (clockwise) so that each "arrow" begins with the tip (arrowhead) followed by the stem. I note that the dashes are curved, correctly following the ellipse, however the arrowheads are incorrectly slanted at the left and right ends of the ellipse. This is a minor "deficiency" but I think TikZ is nigh to perfection when it comes to graphing. So I guess I am just doing it wrong. I found no question that answers this (although one was close). Here is the relevant MWE code: \documentclass[10pt, twoside, a4paper]{report} \usepackage[utf8x]{inputenc} \usepackage[ top=21mm, bottom=21mm, left=12mm, right=8mm]{geometry} \usepackage{tikz} \usetikzlibrary{decorations.markings} \begin{document} \thispagestyle{empty} % no page number \begin{tikzpicture}[decoration={markings,% switch on markings mark=% actually add a mark between positions 0 and 16cm step 30 pt with { \draw (4pt,-4pt) -- (0,0); \draw (4pt,4pt) -- (0,0); } } ] \draw[postaction=decorate,thick,dash pattern=on 20pt off 10pt,x radius=3.9cm,y radius=-0.975cm] (3.9cm,0) ellipse; \end{tikzpicture} \end{document} and it produces this diagram: Correction: I think the arrowheads are correctly slanted. But my solution is cumbersome to create ... is there an easier syntax?

Interpretiert man die Mandelbrot-Menge (eine Teilmenge der Gaußschen Zahlenebenen) als geometrische Figur, so ergibt sie ein Fraktal, das im allgemeinen Sprachgebrauch oft Apfelmännchen genannt wird. Bilder berechnet man, indem man jedem Pixel $(x,y)$ eines Bildes eine komplexe Zahl zuordnet und beginnend mit $z_0 =0$ untersucht, ob und wann die Iterationen anfangen, zu „explodieren“. Bleiben die Werte klein, wird das Pixel häufig schwarz gefärbt, kommt es zu einer „Explosion“ der Zahlenwerte, wird die Anzahl der dafür notwendigen Iterationen als Farbe kodiert. \begin{tikzfigure} \includegraphics[width=0.5\textwidth]{pics/madelbrot.png} \end{tikzfigure} Die ersten mit einem Computer generierten Darstellungen wurden 1978 von Robert W.

I want to create a tree using tikz. However, I have a few constraints. Most of the nodes at all the levels are standard usual nodes. However, I want to have the following at some level (say level 3) in this tree: All nodes at this level should be drawn bigger (perhaps elliptical). Moreover, I also want each of these big nodes to contain some dots. In the picture below, I mark these dots in purple. There is a "home" node for these purple dots where most of them live. And a few of these purple dots appear in other nodes at this level. I can add the tikz code I obtained from online sources to create trees, but it is pretty bare-bones. Please let me know if that would be helpful in getting help with this question. EDIT (Added Later) Here are some variations that I tried so far on overleaf.

I've got a program which is split into some files located in two main folders, src and include, with the header .h files in the include folder while .cpp and .cu files in the other. Here is a little drawing for the whole routine Note#1 this is not exactly what I want to achieve but it may be a starting point. Note#2 here you can find the meaning of the word routine, but here I mean just a complex application split into multiple files. Is there a standard way to represent the tree of the files which a program is composed of? I mean the file tree, along with the folders tree. I'm looking for some solution to even add some of the relations within the files with some arrows. I'd like to use tikz if possible. Right now this is my poor, far-to-be-optimized tikz image I realized: \documentclass[]{standalone} \usepackage{tikz} \usetikzlibrary{arrows,positioning} \usetikzlibrary{calc} \tikzset{ %Define standard arrow tip >=stealth', pil/.style={ ->, thick, shorten <=2pt, shorten >=2pt,}, gpufile/.style={ rectangle, rounded corners, draw=red, very thick, minimum height=2em, minimum width=8em, text centered }, cpufile/.style={ rectangle, rounded corners, draw=black, thick, minimum height=2em, text centered }, header/.style={ rectangle, draw=gray, thin, minimum height=2em, minimum width=5em, text centered }, folder/.style={ rectangle, draw=yellow, thin, minimum height=3em, minimum width=5em, text centered } } \begin{document} \begin{tikzpicture}[node distance=1.5cm, auto,] \tikzstyle{every path}=[-latex,thick] \node[ folder, xshift=-2cm] (src) {src}; \node[ cpufile, right of=src, xshift=40pt] (main) {\texttt{main.cpp}}; \node[ gpufile, right of=main, xshift=40pt, yshift=0pt] (trbdf2) {\texttt{tr-bdf2.cu}} ; \node[ gpufile, right of=trbdf2, xshift=40pt, yshift=0cm ] (jacobian) {\texttt{jacobian.cu}}; \node[ gpufile, right of=jacobian, xshift=60pt ] (inversion) {\texttt{matrix\_inversion.cu}}; \node[ gpufile, right of=inversion, xshift=60pt] (tr) {\texttt{newton\char`_tr.cu}}; \node[ gpufile, right of=tr, xshift=60pt] (bdf2) {\texttt{newton\char`_bdf2.cu}}; \node[ folder, below of=src, yshift=-1cm] (include) {include}; \node[ header, right of=include, xshift=40pt] (libs) {\texttt{libs.h}}; \node[ header, right of=libs, xshift=40pt] (constants) {\texttt{constants.h}}; \node[ header, right of=constants, xshift=40pt] (fdefs) {\texttt{functions\char`_defs.h}}; \node[ header, right of=fdefs, xshift=40pt] (defs) {\texttt{defs.h}}; \node[ header, right of=defs, xshift=40pt] (linsolver) {\texttt{linear\char`_solver.h}}; ; \end{tikzpicture} \end{document} I need to highlight .cu files in the project, they have a different meaning from the clasic .cpp files. While sliding through the tikz library samples the closest I found to what I mean is this example, which is recommended just for a filesystem directory tree though.

I'm trying to draw a simple timeline in tikz. Here's what I have: \documentclass[12pt,a4paper,bibtotoc]{scrartcl} \usepackage[utf8]{inputenc} \usepackage[T1]{fontenc} \usepackage[ngerman]{babel} \usepackage{microtype} \usepackage{tikz} \begin{document} Ablauf der Schadenregulierung bei einem typischen Schadenfall \\ \\ % Zeitstrahl zur Schadenregulierung \begin{tikzpicture} \draw[black, ultra thick, ->] (0,0) -- (2,0) node [below]{Schadeneintritt} --(14,0); \end{tikzpicture} \end{document} What I would like is for there to be a tick on the line at node "Schadeneintritt". I've tried adding tick to the options of the node but that produces an error (apparently tickz doesn't know the tick option). I'm still new to tikz and so far I've only found solutions for full blown axes / coordinate systems. I know that I could do: \draw (2,0.2) -- (2,-0.2); but I wonder whether there's an easier solution (i.e. specifying this directly at the node). Cheers!

How can I draw WBS diagrams (Work breakdown structures) in LaTeX? I need to draw in LaTeX things like: I've searched on the Internet a lot but I've found nothing.
