TikZ

Is there a simple fix (other than not using \i in the math mode) to get the correct character in the following MWE? \documentclass[]{standalone} \usepackage{tikz} \usetikzlibrary{math} \begin{document} \tikzmath{ int \i; \i=7; } \begin{tikzpicture} \node at (0, 0) {ABC ı}; \end{tikzpicture} \end{document} The output of the MWE is

samcarter_is_at_topanswers.xyz provided kindly a solution for the previous question Beamer: What else is possible besides blocks? I struggle with the following now: My beamer is 169. the puzzle pieces don't stretch automatically. If I change scale, they change size, but puzzle title and position don't move automatically. See red piece. I have no feel for the right numbers, hence that would mean multiple compilation to test for the right position. Green starts at 0, but red finishes somewhere else as I manually set the starting point. Would it not be nicer to have it as flexible number of puzzle pieces? I know tikz can calculate and one could define lengths, but I did not achieve a result. If everything depends on number of pieces it could be more logical? How to shift the position of the itemize automatically, so it uses the most reasonable text width of a puzzle piece? My MEW runs through, but looks ugly . I would be very grateful, if somebody could elaborate better how to define number of puzzle pieces, distribute them over the whole text with (here also for 16/9 ratio) , and have the puzzle titles also moved with the scaling, i.e. red puzzle title is in the red piece. Itemize text uses a whole, reasonable puzzle piece width. \documentclass[aspectratio=169]{beamer} % test aspect ratio \usetheme{Madrid} \useoutertheme{shadow} \useoutertheme{infolines} \useoutertheme[subsection=false]{miniframes} \usepackage{tikz} \usetikzlibrary{calc} \usepackage{jigsaw} \begin{document} \begin{frame}{Puzzle Example} \begin{tikzpicture}[ mypuzzle/.style={ text=violet, text width=2cm, font=\footnotesize, align=center, thick, scale=4, } ] \path (0,0) pic[ mypuzzle, fill=teal!30, pic text={ \begin{itemize} \item test \item test \end{itemize} }, pic text options={xshift=-0.3cm,yshift=0.5cm} ]{piece={1}{1}{0}{0}}; \node[text width=3cm,fill=teal,inner xsep=0pt,anchor=south west,align=center,text=white] at (0,3) {Puzzle Piece 1}; \path (4,0) pic[ mypuzzle, fill=violet!30, pic text={ \begin{itemize} \item test \item test \end{itemize} }, pic text options={yshift=0.5cm} ]{piece={-1}{-1}{0}{-1}}; \node[text width=3cm,fill=violet,inner xsep=0pt,anchor=south west,align=center,text=white] at (3,3) {Puzzle Piece 2}; \path (8,0) pic[ mypuzzle, fill=orange!30, pic text={ \begin{itemize} \item test \item test \end{itemize} }, pic text options={xshift=0.3cm,yshift=0.5cm} ]{piece={-1}{-1}{0}{1}}; \node[text width=3cm,fill=orange,inner xsep=0pt,anchor=south west,align=center,text=white] at (6,3) {Puzzle Piece 3}; \path (11.5,0) pic[ mypuzzle, fill=red!40, pic text={ \begin{itemize} \item test \item test \end{itemize} }, pic text options={xshift=0.3cm,yshift=0.5cm} ]{piece={-1}{0}{0}{1}}; \node[text width=3cm,fill=red,inner xsep=0pt,anchor=south west,align=center,text=white] at (9,3) {Puzzle Piece 4}; \end{tikzpicture} \end{frame} \end{document}

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 recently stumbled over this issue when declaring own tikz shapes with makeshape, but see for yourself: \documentclass{article} \usepackage{tikz} \usetikzlibrary{positioning,fit} \usepackage{demoProblem} \begin{document} \begin{tikzpicture} \node[draw] (origin) {origin}; \begin{scope}[local bounding box=A1] \node[myShape, right=3cm of origin] {}; \end{scope} \node[draw,fit=(A1), label=below:{box}] (box) {}; \end{tikzpicture} \begin{tikzpicture} \node[draw] (origin) {origin}; \begin{scope}[local bounding box=A1] \node[myShape, right=3cm of origin, left] {}; \end{scope} \node[draw,fit=(A1), label=below:{box}] (box) {}; \end{tikzpicture} \begin{tikzpicture} \node[draw] (origin) {origin}; \begin{scope}[local bounding box=A1] \node[myShape] at (3,0) {}; \end{scope} \node[draw,fit=(A1), label=below:{box}] (box) {}; \end{tikzpicture} \end{document} With the following demoProblem.sty: \RequirePackage{makeshape} \def\myShapeAnchor{ \pgf@xa=\pgfshapeminwidth \pgf@ya=\pgfshapeminwidth \pgf@xa=.5\pgf@xa \pgf@ya=.5\pgf@ya \pgfpathmoveto{\pgfpoint{.75\pgf@xa}{.4\pgf@ya}} \pgfpathlineto{\pgfpoint{-.75\pgf@xa}{.4\pgf@ya}} \pgfpathlineto{\pgfpoint{-.97\pgf@xa}{-.18\pgf@ya}} \pgfpathlineto{\pgfpoint{-.99\pgf@xa}{-.18\pgf@ya}} \pgfpathlineto{\pgfpoint{-.99\pgf@xa}{-.4\pgf@ya}} \pgfpathlineto{\pgfpoint{.99\pgf@xa}{-.4\pgf@ya}} \pgfpathlineto{\pgfpoint{.99\pgf@xa}{-.18\pgf@ya}} \pgfpathlineto{\pgfpoint{.97\pgf@xa}{-.18\pgf@ya}} \pgfpathclose % \pgfusepath{stroke} } \def\myShapeBorder{ % Deckel \pgfmoveto{\northeast \pgf@x=.75\pgf@x \pgf@y=.4\pgf@y} \pgflineto{\northeast \pgf@x=.97\pgf@x \pgf@y=-.18\pgf@y} \pgflineto{\northeast \pgf@x=-.97\pgf@x \pgf@y=-.18\pgf@y} \pgflineto{\northeast \pgf@x=-.75\pgf@x \pgf@y=.4\pgf@y} \pgfclosepath \pgfusepath{stroke} } \pgfdeclareshape{@myShape}{ \setpaths{\myShapeAnchor}{\myShapeBorder} \savedanchor\northeast{% \pgf@x = \pgfshapeminwidth \pgf@y = \pgfshapeminwidth \pgf@x=.5\pgf@x \pgf@y=.5\pgf@y } \anchor{north}{\northeast \pgf@y=.4\pgf@y \pgf@x=0pt} \anchor{east}{\northeast \pgf@x=.9\pgf@x \pgf@y=0pt} \anchor{south}{\northeast \pgf@x=0pt \pgf@y=-.4\pgf@y} \anchor{west}{\northeast \pgf@x=-.9\pgf@x \pgf@y=0pt} } \tikzset{ myShape/.style 2 args={ shape=@myShape, minimum size=#1, fill=#2 }, myShape/.default={1cm}{black} } All this results in the following output: You see the boxes in the first two lines are extended to the right/left compared what I'd expect. Now I already have that \pgfusepath{stroke} in the \myShapeAnchor which currently is commented out. Adding it back in, I see the path specified there is drawn/evaluated right/left of the actual node correlating to the extend. Now I think I already found out the issue is that when using the positioning library, pgf/tikz evaluates the anchorpath first in order to know where to place the node. Now in this evaluation, the node draws a path which is captured by the bounding box, resulting in this weird extension of the box. Do I see this correctly? Now I wonder of course if this can be fixed with the shape (I'd still like to use the bounding box). Looking at the docs of makeshape, it says Its key features are: a mechanism for specifying the \anchorborder behaviour as a path Am I correct in that when I want to fix this at the shape level, I need to stop using makeshape essentially (thereby go the hard way of declaring the anchorborder with potentially complex operations)? (or at least makeshape is not of much help anymore when not using that feature)

for a beamer presentation I have 4 blocks with itemize env next to each other. I was wondering if there is a more interesting design for the blocks. I thought about 4 puzzle pieces connected. But I don't know how to connect the puzzle pieces automatically nor how to place an itemize env in one piece. Or how to have a better design? The pieces will stretch probably with more items/text, but that is fine for me. Some irregular puzzle.

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?

The tikz picture is moved to the right relative to the page layout. I want to stop that unintended movement. In the document class article, I've set the paper width and height to be 36in and 24in, respectively. The margins are 0.5in all the way around. The rectangle has dimensions 24.99in and 22.99in. If I set the rectangle dimensions to 25inand 23in, then it spills over into a second page. Separate problem. The rectangle should take up the entire page save for the margins. As seen in the first two images, the rectangle is moved to the right ~1/8th of an inch. How do I stop that so the tikz environment, and consequently the rectangle, is centered on the page? Here's my code for the following images: \documentclass[]{article} \usepackage[showframe]{geometry} \usepackage{tikz} \geometry{paperwidth=36in, paperheight=24in, left=0.5in, right=0.5in, top=0.5in, bottom=0.5in} \begin{document} \begin{tikzpicture}[x=1in,y=1in] \draw[draw=red, fill=orange, opacity=0.5] (0,0) rectangle (34.99,22.99); \end{tikzpicture} \end{document} Upper left corner: Upper right corner: Whole Image:

This is another subcolumn problem in tikzposter. This question addresses a similar issue: Distance between subcolumns with Tikzposter. I use the accepted solution (a work around), but my poster has three subcolumns, and the second subcolumn spacing is still over-sized. This question: Subcolumn horizontal spacing problem with tikzposter presents the same two-subcolumn issue as the first referenced question above, but has no answer; and this question: subcolumns not working correctly in tikzposter concerns a different subcolumn issue. Following the work-around in the first referenced question, when I use subcolspace=-1.0cm the first subcolumn spacing is eliminated as shown in the image below. However the second subcolumn spacing is still oversized (see image below). When I change subcolspace=-1.0cm to subcolspace=-2.0cm, the second subcolumn spacing is reduced to zero but the first has overlap. Is there a known hack or work around to get both subcolumns spacings reduced to zero width?

When I fill a TikZ matrix node that contains text in typewriter font, the color goes beyond the rectangle drawn. Writing anchor=center inside nodes does align the color inside the rectangle, but the text is no longer at the base. Is it possible to fill the nodes and keep the text at base level line?

I'm trying to draw a parabola ( y = t^2 ) in TikZ using the let operation to extract coordinates from a point (B) and use them to define the domain for a plot. However, the following code does not draw count domains correct: \documentclass[tikz, border=1cm]{standalone} \usetikzlibrary{calc} \begin{document} \begin{tikzpicture} \coordinate (B) at (-3, 3); \draw[variable=\t] let \p1=(B) in plot[domain=\x1:\y1] (\t, {\t*\t}); \end{tikzpicture} \end{document} I expect this code to draw the parabola ( y = t^2 ) in a range defined by the x- and y-coordinates of point (B) (\x1=-3, \y1=3). However, no curve is drawn. How do I properly convert dimensional units to dimensionless units so that the point coordinate matches its value for domain? Of course, this is a toy example, but in a real problem I need to take the bounds from the coordinates of the points. Any insights or alternative solutions would be greatly appreciated!

My goal is to recreate the following table (focus on the red part): Below is my MWE: \documentclass{article} \usepackage{tabularray} \UseTblrLibrary{tikz} \begin{tblrtikzbelow} \draw[red] (3-2.east) -- (3-3.center); \draw[red] (3-3.center) -- (5-3.center); \draw[red] (5-2.east) -- (5-3.center); \end{tblrtikzbelow} \begin{document} \begin{tblr} { width=\textwidth, colspec={X[c]X[c]|X[c]}, } \hline Solution & Scores & \SetCell{l}\quad Comment \\ \hline $a^2$ &&\\ $=b^2+c^2$ & 1 point &\\ $=2^2+3^2$ && \qquad\quad \color{red}{Good!}\\ $=x^2+y^2$ && \end{tblr} \end{document} I am currently facing two problems: The red lines should be dynamic, instead of manually typing cell indices like (3-2). I tried to use \SetChild{id*=Start} and \SetChild{id*=End} and attempted the following: \begin{tblrtikzbelow} \draw[red] (Start.east) -- (End.center); \end{tblrtikzbelow} It doesn't work. I have no idea how to use \node in tblrtikzbelow. I tried something like \node[red] (2-3.center); but it also doesn't work. I would like it to be positioned at the middle right of the red vertical line. The documentation about this part has too little examples so I have a difficult time understanding tikz in tabularray. I would be very grateful if anyone could help me on this.

The target is drawing 123000 over a pie chart (don´t worry about people over people). But the problem is that with only 50 people is obtained the error: ! Dimension too large. The 'mwe' runs well drawing 45 people (\newcommand{\imax}{45}), but fails when you type 50 or more instead. \documentclass[10pt,a5]{article} \usepackage[utf8]{inputenc} \usepackage[spanish]{babel} \usepackage{graphicx} \usepackage{tikz} \usetikzlibrary{calc} \usepackage{fontawesome7} \begin{document} \begin{tikzpicture} \newcommand{\PieRadius}{6} \newcommand{\imax}{45} % The target is drawing 123000 people over a pie.

Note 1.- I think that TikZ may be not the ideal tool for the graphic, but nowadays I´m not using any kind of language program, so I try using TikZ. Note 2.- I tried changing main_memory.hugetex = ... in texmf.cnf as any other posts suggested. Curiosity (It´s not the question, it´s the final target in another phase).- The origin of this is the sensation of a not accurate of a graph when I read a few days ago: enter link description here What I finally will try, after solve the problem of ddrawing thounsands os people, is sketched on th next image

I am trying to draw a cube with spheres on 4 vertices in perspective (I'll have then to insert a gray transparent plane but that seems doable). I am dealing with the first sphere... for which I tried to use a \fill[ball] command, but this flatten the circle as it is not a real 3D ball but rather a 2D circle... would anyone have suggestions on how to plot spheres on 4 corners ? (I try to produce a tetrahedral symmetry for more details so I'll also have a sphere in the center of the cube). Here is a MWE: \documentclass[tikz]{standalone} \usetikzlibrary{perspective} \begin{document} \begin{tikzpicture}[3d view,scale=2] \draw (0,0,0)--(1,0,0); \draw (0,1,0)--(0,0,0); \draw[dashed] (1,0,0)--(1,1,0); \draw[dashed] (1,1,0)--(0,1,0); \draw[dashed] (1,1,0)--(1,1,1); \draw (0,0,1)--(1,0,1)--(1,1,1)--(0,1,1)--cycle; \draw (0,0,0)--(0,0,1); \draw (1,0,0)--(1,0,1); \draw (0,1,0)--(0,1,1); \fill[ball color=blue!20,opacity=1.7] (0,0,1) circle (0.05) node[above] {a}; \end{tikzpicture} \end{document} and what it produces: Have a good day !

I'm trying to plot some 3D data which is saved in a csv file. Plotting just the color map works fine, but I also need to add the contour lines, so I get a result similar to this: My intuition was that it's possible to simply add another \addplot3[...] table {...} block to my existing plot like this: \begin{tikzpicture} \begin{axis}[...] \addplot3[surf] table {data.csv}; % <- this is my existing plot, which works \addplot3[...] table {data.csv}; % <- this should be okay?! \end{axis} \end{tikzpicture} This question seems to be about the exact same issue, so I tried to adapt the answer into my document, but to no avail. In the end I found that even this minimal example doesn't compile for me (which is the accepted answer from the mentioned question): \documentclass[border=1 cm]{standalone} \usepackage{pgfplots} \pgfplotsset{compat=newest} \begin{filecontents}{data_test.dat} 0 0 3 0 2 1 0 3 2 1 0 1 1 2 2 1 3 2 2 0 1 2 2 2 2 3 1 \end{filecontents} \begin{document} \begin{tikzpicture} \begin{axis}%[view={0}{90}] \addplot3[surf] table {data_test.dat}; \addplot3[contour lua={levels={1,2,3}}] table {data_test.dat}; \end{axis} \end{tikzpicture} \end{document} When I try to compile this in my TeXworks installation with the LuaLaTeX engine (using the option --shell-escape) I get the following error : ! Package pgfkeys Error: I do not know the key '/tikz/contour lua', to which you passed 'levels={1,2,3}', and I am going to ignore it. Perhaps you misspelled it. This error message looks quite similar to the kind of errors I had with my original document, but why do I get it even in this MWE? Since the OP of the mentioned question has the exact same requirements as I do, I'm confident that my problem is solved once I'm able to compile the MWE above. Thanks for spending your time!

For a visualization I have in mind I'd like to create an rectangular arrangement of filled circles using different colors. For example, something like this: + + + + + + + * + + * * + * * * * * * * Where the + would be blue circles and the * would be red circles. I created a somewhat functional version of this adapted from some other question: \documentclass[border=5pt,tikz,multi]{standalone} \usetikzlibrary{fit,positioning} \begin{document} \begin{tikzpicture}[ultra thick] \coordinate (c0) at (0,0); \foreach \i [count=\j, evaluate=\j as \k using \j-1, evaluate=\j as \n using { \j>0 ? "blue" : "red" }] in {1,...,3} \node (c\j) [right=5 pt of c\k |- c0, circle, anchor=north west, minimum size=1mm, draw, fill=\n, \n] {}; \coordinate (c0) at (0,1); \foreach \i [count=\j, evaluate=\j as \k using \j-1, evaluate=\j as \n using { \j>1 ? "blue" : "red" }] in {1,...,3} \node (c\j) [right=5pt of c\k |- c0, circle, anchor=north west, minimum size=1mm, draw, fill=\n, \n] {}; \coordinate (c0) at (0,2); \foreach \i [count=\j, evaluate=\j as \k using \j-1, evaluate=\j as \n using { \j>2 ? "blue" : "red" }] in {1,...,3} \node (c\j) [right=5pt of c\k |- c0, circle, anchor=north west, minimum size=1mm, draw, fill=\n, \n] {}; \end{tikzpicture} \end{document} Which renders like this: I have a few problems with that: I can't find a way to make the vertical and horizontal margins between the circles equal. Meaning all margins inside the arrangement of circles should be equal. In the above image, the circles are too large, the vertical distances are too much and the horizontal margins are too small. It requires quite a bit of code, I wonder if there is a more convenient way to tell which circles should have which color.

I want to draw a diagram as the image below, but it is difficult for me to start. The height of vertical line represent the temperature, and the slop of slash is fix. Number above the vertical line is the temperature, and number below it is the time. It is possible to wrap the drawing into a single function like this? \drawPCR{[95.0,11:00]}{[94.0,1:00],[59.0,1:00],[72.0,1:00]}{[60.0,45:00],[4.0,∞]}

My questions are: how come such a symmetric shape resulted in uneven dimensions? Is there a way to predict the image dimensions from the TikZ parameters (e.g. radius)? Is there a natural way to get a circle with equal dimensions in TikZ? Thanks.

Context I personally am a fan of the Wolfram Language, especially for its symbolic notation. The Wolfram Language uses the following symbols for arcs and edges respectively: Suppose I wish to type some Mathematica pseudo-code and use these conventions rather than their "full form" (\[DirectedEdge] and \[UndirectedEdge]). Then I can, somewhat, recreate these icons using tikz: \newcommand{\ue}[1]{% \begin{tikzpicture}[#1]% \draw[fill = black] (.25ex,.25ex) circle (.3ex); \draw[thick] (.55ex,.25ex) -- (1.55ex,.25ex);% \draw[fill = black] (1.85ex, .25ex) circle (.3ex);% \end{tikzpicture}% } \newcommand{\de}[1]{% \begin{tikzpicture}[#1]% \draw[fill = black] (.25ex,.25ex) circle (.3ex); \draw[thick, ->] (.55ex,.25ex) -- (1.85ex,.25ex);% \end{tikzpicture}% } Where ue and de stand for undirected / directed edge respectively. While I would prefer to use edge and arc, arc is already taken in the namespace. To be fair, using these symbols doesn't look like the worst thing ever seen when typeset: \noindent\textbf{Adjacency}: if there exists an edge $e \in \mathbf{E}$, for $v_i, v_j \in \mathbf{V}$ such that $e$ is defined by $v_i$~\ue{}~$v_j$ (equivocally $v_j$ \ue{} $v_i$), then $v_i$ \& $v_j$ are said to be adjacent. Personally, I am in favor of these symbols rather than the explicit stating of an (un)ordered set of two vertices, and walks look ok-ish as well: Question While these tikz drawings work in the given cases, I have noticed that in caption environments the symbols is no longer centered with the text. Further, spacing can be an issue. How can the following be achieved? automatic binding (the preceding and succeeding character elements must be in the same line). automatic centering to the preceding / succeeding character. the ability to work in the math environment. easy scaling. Also, you opinion about using these glyphs in general would be appreciated. Be honest, how ugly are they?

How can I draw these solid figures with LaTeX? \begin{tikzpicture} \pgfmathsetmacro{\cubex}{5} \pgfmathsetmacro{\cubey}{1} \pgfmathsetmacro{\cubez}{3} \draw[red,fill=yellow] (0,0,0) -- ++(-\cubex,0,0) -- ++(0,-\cubey,0) -- ++(\cubex,0,0) -- cycle; \draw[red,fill=yellow] (0,0,0) -- ++(0,0,-\cubez) -- ++(0,-\cubey,0) -- ++(0,0,\cubez) -- cycle; \draw[red,fill=yellow] (0,0,0) -- ++(-\cubex,0,0) -- ++(0,0,-\cubez) -- ++(\cubex,0,0) -- cycle; \end{tikzpicture} I have used that code. How can I draw and write the quotes and dimensions?

Here's the code I have \documentclass{article} \usepackage{tikz} \usetikzlibrary{arrows} \tikzset{ treenode/.style = {align=center, inner sep=0pt, text centered, font=\sffamily}, arn_n/.style = {treenode, circle, white, font=\sffamily\bfseries, draw=black, fill=black, text width=1.5em},% arbre rouge noir, noeud noir arn_r/.style = {treenode, circle, red, draw=red, text width=1.5em, very thick},% arbre rouge noir, noeud rouge arn_x/.style = {treenode, rectangle, draw=black, minimum width=0.5em, minimum height=0.5em}% arbre rouge noir, nil } \begin{document} \begin{tikzpicture}[->,>=stealth',level/.style={sibling distance = 5cm/#1, level distance = 1.5cm}] \node [arn_n] {1} child{ node [arn_r] {2} child{ node [arn_n] {4} child{ node [arn_r] {6}} child{ node [arn_r] {7}} } child{ node [arn_r] {3} edge from parent node[above left] {$x$} } ; \end{tikzpicture} \end{document} I want to write something beside each arrow... I tried using edge from parent node[above left]{$x$} But it messes up the whole thing, probably cause I'm inserting it in the wrong location. Plus, I wanna write something beside each circle.. Is there a way to do that too? Help please!

I'm trying to draw a tree like this: The root has three children and every of this two... The nodes in the first two tiers has additional informations.. I searched for examples like that, but could only find trees, which children always have the same amount of children (for example here: http://www.texample.net/tikz/examples/feature/trees/). I thank you for your help!

How can I generate the above image using TikZ (possibly other methods will work if they produce better looking results)? I would like to have a nicely shaded (not so dark image) without gridlines and possibly enough opacity on the torus to see the hidden part of the helix. The image given is very close to what I want though and I would just try to make it visually a little better.
