TikZ

This question is similar to this question, but not exactly the same. I have the following code: \documentclass[tikz,border=5pt]{standalone} \begin{document} \begin{tikzpicture} \draw[help lines] (-1,-1) grid (7,2); \draw[thick,magenta] (0,0) .. controls (3,3) and (4,-1) .. % coordinate[pos=.3] (A) %<- point start of thick line % coordinate[pos=.5] (B) %<- point end of thick line (6,0); \clip (2,0) rectangle (3,3); \draw[line width=3pt,cyan] (0,0) .. controls (3,3) and (4,-1) .. (6,0); \end{tikzpicture} \end{document} Noted that the GREEN cut is what I was after, the cut should along the path, but not the \clip-ed rectangle. What I saied is not the same as Paul Gaborit's solution, is that I want to control the proportion of (says 0.3 and 0.5, and coloe them thicker) the "subpath". The solution with: decoration={ show path construction, curveto code={ \addtocounter{pos}{1} \pgfmathtruncatemacro{\min}{#1 - 1} \ifthenelse{\thepos < #2 \AND \thepos > \min}{ \draw[#3] (\tikzinputsegmentfirst) .. controls (\tikzinputsegmentsupporta) and (\tikzinputsegmentsupportb) .. (\tikzinputsegmentlast); }{} } } points here \tikzinputsegmentfirst, \tikzinputsegmentsupportX and \tikzinputsegmentlast looks not easy to control two points position as pos=0.3, is there any better solution? Any possible(plain-TikZ,tkz-elements,luadraw) are all welcome!

When I saw this thread How to customize CircuiTikz ac - dc symbols or this one Showcase of beautiful typography done in TeX & friends, I had the idea to add a showcase for electrical circuit diagrams. The package would typically be circuitikz. Feel free to post your large, small, or elegant circuit diagrams here in the community wiki. (I will also add some examples occasionally.) Attach your codes (if possible); this would be a great opportunity to learn from your coding and your style. \documentclass[margin=5pt, multi=circuitikz]{standalone} \usepackage{circuitikz} \begin{document} \begin{circuitikz}[european resistors] \draw[] (0,0) to[R=$R_1$, a_=$1\Omega$, name=R1, invert] (3,0); \end{circuitikz} \end{document}

Asymptote appears to be correctly installed in my MiKTeX distribution; however, the document does not compile and produces the following error: Package asymptote Warning: file `spy-1.pdf' not found on input line 15. (spy.aux)) No pages of output. Transcript written on spy.log. Sorry, but "MiKTeX Compiler Driver" did not succeed. I do not use Asymptote very often, so I am not sure about the cause of the problem. It is possible that the solution is related to what is discussed in the following TeX.StackExchange threads: 'filename-1.pdf' not found Asymptote Asymptote Code Generates .asy Files, But Asymptote Execution Fails In particular, I have not yet tried the solution proposed by the user user279206, and I do not know whether there is an alternative approach that would allow me to compile the document correctly with my MiKTeX distribution. In a previous question, I also asked whether it is possible to obtain the same arrow tip styles provided by Asymptote using TikZ: Arrows with spherical (conical) tips Since I do not understand Asymptote code, I kindly ask whether it would be possible to modify the original code by removing everything that is not strictly necessary, in order to obtain only the figure related to spherical coordinates, without the volume element and without additional unnecessary details to obtain this with the portion of a sphere. In TikZ there is a result: https://tikz.net/spherical_1/ This is my goal:

I am still new to LaTeX and I am trying to label the areas of my economics diagram in LaTeX. To do this, I am trying to label the areas using barycentric coordinates, because I want the label to appear in the centre of the triangle. To do this I am calculating the intersections of the lines and using barycentric coordinates. However, I am getting the error message. What would be the correct way to do this?

I'm trying to recreate this image on 5mm grid paper using the original dimensions. It's not a big problem; I'm just looking for some fine-tunings inside the circuitikz-package. I've tested a few keys, but I'm wondering: What is the correct method: to add a longer voltage arrow that's a bit further away from the source? to add a current arrow at the shown position in a package-like way (regular TikZ is clear)? PS: I would also like to reduce the (global setting!) size of the arrowheads and the control points ("poles", I haven't quite understood chapter 6.1 yet); but that might be too much for one thread.

Consider the following MWE. \documentclass{beamer} \usepackage{tikz} \begin{document} \begin{frame} \begin{onlyenv}<2>% \tikz [remember picture, overlay] \node (A) {A};% \hskip 5em \tikz [remember picture, overlay] \node (B) {B};% \tikz [remember picture, overlay] \draw (A) -- (B);% \end{onlyenv}% \end{frame} \end{document} It produces the expected output (an empty page followed by one where A and B are connected by a line), but produces two unusual warnings. Package pgf Warning: Returning node center instead of a point on node border. D id you specify a point identical to the center of node ``B''? on input line 17. Package pgf Warning: Returning node center instead of a point on node border. D id you specify a point identical to the center of node ``A''? on input line 17. The warning is surprising because usually in TikZ, writing (A) is equivalent to writing (A.center). Indeed, the warnings only seem to appear in this rather particular case where the drawing is split over several tikzpictures (using remember picture), both points ((A) and (B)) have the same coordinates ((0,0) in this example) and there is an overlay where the picture is not drawn (here the first one). Why is there a warning here? Is this a bug? If so, in TikZ or in beamer? Is there an easy way to avoid it (without changing the drawings)?

Just out of interesst, I asked myself how to configure a muxdemux such that it has the exact same dimensions as an european resistor (european inductor), but with three muxdemux-pins on the underside. (Note: The exact target image is attached.) Here is my approach: \documentclass[border=5pt]{standalone} \usepackage{circuitikz} \begin{document} \begin{circuitikz}[european resistors, IPP/.style={muxdemux, muxdemux def={Lh=0.8, Rh=0.8, NL=1, NR=1, NB=3, NT=0, w=2}, %muxdemux label={B2=abc, BL1=1, BL2=2, BL3=3,}, %external pins width=0.4, circuitikz/muxdemuxes/fill=gray!25, }, ] \node [IPP, align=center](A) at (0,0) {}; \draw[] (-1,0.5) to[R, fill=gray!25] +(2,0); \end{circuitikz} \end{document}

I want to make the following diagram: But this: \documentclass[a4paper,12pt]{article} \usepackage[compat=1.1.0]{tikz-feynman} \usepackage{xcolor} \definecolor{uctgreen}{rgb}{0,0.45,0} \newcommand\uct[0]{{\color{uctgreen}{u}\color{red}{c}\color{blue}{t}}} \tikzfeynmanset{ every diagram={very thick}, } \begin{document} \resizebox{5cm}{5cm}{ \begin{tikzpicture}[yscale=0.7, xscale=1.4] \begin{feynman} % ~~~ defining the vertices ~~~~~~ \vertex (i1) ; \vertex[below right=of i1] (v1); \vertex[ right=of v1] (v2); \vertex[above right=of v2] (o1); % ~~~ Z-related ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ \vertex at ($(v1)!.5!(v2) - (0,15mm)$) (v3); % middle, below \vertex[below=1cm of v3] (v4); % <<< Z "length" % ~~~ lower part ~~~~~~~~~~~~~~ \vertex[below left = 2cm of v4] (i2); % one way to modify \vertex[below right= 2cm of v4] (o2); % ~~~ drawing this diagram ~~~~~~~~~~~~~~~~~~~~~ \diagram*{ {[edges={fermion}](i1) --[edge label=s] (v1) --[edge label=\uct] (v2) --[edge label=d] (o1)}, (v1) --[photon, half right, edge label'=W] (v2), (v3) --[photon, edge label'=Z] (v4), {[edges={fermion}](i2) --[edge label'=$\nu$] (v4) --[edge label'=$\nu$] (o2)}, }; \end{feynman} \end{tikzpicture} } \end{document} produces this: How can I add labels to both sides of the W and make the W-Z vertex match up?

I’ve been working on a variation of the interactive puzzle from this excellent post on TeX StackExchange: 🔗 The TikZ Game Package – a TeX.SX Project ❓Goal I'd like to shuffle the pieces of the puzzle at the start (instead of them being in order) and still keep the interactive movement functionality working (i.e. clicking tiles to move them like a sliding puzzle). ✅ What I have working The puzzle layout builds correctly using TikZ, ocgx2, and media9. I implemented a manual shuffle using a LaTeX macro (\ShuffleIndex) to define the tile order. The initial view of the puzzle shows the image shuffled correctly. ❌ What is broken The JavaScript interaction no longer works after applying the shuffle. Clicking on the tiles gives an error: ReferenceError: onButtonClick is not defined It seems the function is not visible globally or the OCGs are not properly indexed. 💡 What I'm asking Would anyone be able to: Help fix the JavaScript so it works with the shuffled layout? Or alternatively — provide a working example based on the original post, but with the puzzle pieces already shuffled at start? 📎 What I’ve tried Here’s my current version (almost working, but with JS errors): \documentclass[tikz,margin=1mm]{standalone} \usepackage{xsavebox} \usepackage[tikz]{ocgx2} \usepackage{media9} \usepackage{multido} \usepackage{xcolor}\pagecolor{gray} \usepackage{multido} \usepackage{ifluatex} \ifluatex\def\pdfpageattr{\pdfvariable pageattr}\fi \usepackage{tikzmarmots} % imagem base \begin{xlrbox}{Image} \begin{tikzpicture} \useasboundingbox (0,0) rectangle (4.4,4.4); \node at (2.2,2.2) {\tikz\marmot[scale=2.1];}; \end{tikzpicture} \end{xlrbox} % peças do puzzle \multido{\nX=0+1.1,\iI=0+1}{4}{% \multido{\nY=3.3+-1.1,\iJ=0+1}{4}{% \ifnum\numexpr\iI+\iJ\relax>0 \begin{xlrbox}{Image.\the\numexpr\iI+\iJ*4\relax} \begin{tikzpicture} \clip (\nX,\nY) rectangle ++(1.1,1.1); \node[anchor=south west,inner sep=0pt] at (0,0) {\theImage}; \end{tikzpicture} \end{xlrbox} \fi } } \newcommand\MyStatus[2]{\ifnum#1=#2 visible\else invisible\fi} % JavaScript \pdfpageattr{ /AA << /O << /S/JavaScript /JS ( var tile=[], oldTile=[]; for(var i=0;i<4;i++){ tile[i]=[]; oldTile[i]=[]; for(var j=0;j<4;j++){ tile[i][j]=[]; oldTile[i][j]=i+j*4-1; } } var ocg=this.getOCGs(this.pageNum); for(var k in ocg){ var n=ocg[k].name.split('.'); tile[n[0]][n[1]][n[2]-1]=ocg[k]; } var si=0,sj=0; function onButtonClick(i,j){ if(si==i && sj!=j){ for(var y=sj;y!=j;sj<j?y++:y--){ if(y!=sj) tile[i][y][oldTile[i][y]].state=false; oldTile[i][y]=oldTile[i][sj<j?y+1:y-1]; tile[i][y][oldTile[i][y]].state=true; } } else if(sj==j && si!=i){ for(var x=si;x!=i;si<i?x++:x--){ if(x!=si) tile[x][j][oldTile[x][j]].state=false; oldTile[x][j]=oldTile[si<i?x+1:x-1][j]; tile[x][j][oldTile[x][j]].state=true; } } if(si==i||sj==j){ if(oldTile[i][j]>-1) tile[i][j][oldTile[i][j]].state=false; oldTile[i][j]=-1; si=i; sj=j; } } ) >> >> } \def\ShuffleIndex#1{% \csname ShuffleValue#1\endcsname% } \expandafter\def\csname ShuffleValue0\endcsname{5} \expandafter\def\csname ShuffleValue1\endcsname{12} \expandafter\def\csname ShuffleValue2\endcsname{3} \expandafter\def\csname ShuffleValue3\endcsname{14} \expandafter\def\csname ShuffleValue4\endcsname{1} \expandafter\def\csname ShuffleValue5\endcsname{6} \expandafter\def\csname ShuffleValue6\endcsname{11} \expandafter\def\csname ShuffleValue7\endcsname{9} \expandafter\def\csname ShuffleValue8\endcsname{8} \expandafter\def\csname ShuffleValue9\endcsname{2} \expandafter\def\csname ShuffleValue10\endcsname{7} \expandafter\def\csname ShuffleValue11\endcsname{10} \expandafter\def\csname ShuffleValue12\endcsname{15} \expandafter\def\csname ShuffleValue13\endcsname{4} \expandafter\def\csname ShuffleValue14\endcsname{13} \expandafter\def\csname ShuffleValue15\endcsname{0} \begin{document} \newcount\shufcount \shufcount=0 \begin{tikzpicture} \multido{\nX=0+1.1,\iI=0+1}{4}{% \multido{\nY=3.3+-1.1,\iJ=0+1}{4}{% \edef\CellIndex{\the\numexpr\iI+\iJ*4\relax}% \edef\RandIndex{\ShuffleIndex{\CellIndex}}% \multido{\iK=1+1}{15}{% \begin{scope}[ocg={ref=\iI.\iJ.\iK,% status=\MyStatus{\ShuffleIndex{\the\numexpr\iI+\iJ*4\relax}}{\iK}}]% \node[anchor=south west,inner sep=0pt]% at (\nX,\nY) {\xusebox{Image.\iK}};% \end{scope}% }% \draw[line width=0,% postaction={% path picture={% \node[anchor=south west,inner sep=0pt]% at (path picture bounding box.south west)% {\mediabutton[jsaction={onButtonClick(\iI,\iJ);}]{% \tikz \useasboundingbox% (path picture bounding box.south west)% rectangle% (path picture bounding box.north east);}};% }% }]% (\nX,\nY) rectangle ++(1.1,1.1);% }% }% \end{tikzpicture} \end{document} I’d appreciate any tips or corrections.

I found this to be the most complete package, which is why I insist on using it. I compiled all available LaTeX packages from source last month so I'm also confident I have everything up to date and working. In the docs it recommends this program to produce .tex files: I definitely got a file to succeed, but it really did take very long (probably at least 10 minutes), and I noticed only 1 of my 8 CPU cores was being used. Does that mean I have to divide the file up, so at least every CPU core works on one piece? I heard LaTeX doesn't support multi-core operation. For reference, here is a .tex file I have just generated. This is where it typically gets stuck on in the CLI: yalihupokn@zoqu-endiman:~/Downloads$ latex fine.tex This is pdfTeX, Version 3.141592653-2.6-1.40.28 (TeX Live 2025) (preloaded format=latex) restricted \write18 enabled. entering extended mode (./fine.tex LaTeX2e <2025-11-01> L3 programming layer <2025-12-29> (/home/yalihupokn/install-tl-20260102/2025/texmf-dist/tex/latex/base/article.cl s Document Class: article 2025/01/22 v1.4n Standard LaTeX document class (/home/yalihupokn/install-tl-20260102/2025/texmf-dist/tex/latex/base/size10.clo )) (/home/yalihupokn/install-tl-20260102/2025/texmf-dist/tex/latex/lm/lmodern.sty) (/home/yalihupokn/install-tl-20260102/2025/texmf-dist/tex/latex/base/fontenc.st y (/home/yalihupokn/install-tl-20260102/2025/texmf-dist/tex/latex/lm/t1lmr.fd)) (/home/yalihupokn/install-tl-20260102/2025/texmf-dist/tex/latex/base/inputenc.s ty) (/home/yalihupokn/install-tl-20260102/2025/texmf-dist/tex/latex/amsmath/amsmath .sty For additional information on amsmath, use the `?' option.

I am using TikZ in a Beamer slide to create a two-column layout: the left column contains a justified text block the right column contains an image inside a framed node Both nodes should be top-aligned, so that the top of the image frame aligns exactly with the top of the text block. However, my current code aligns the image relative to the center or east anchor of the text node, which causes a vertical misalignment when the text height changes. I would like the image frame to be aligned with the top edge of the text block, regardless of the text height. Question How can I position the image node so that its top edge is aligned with the top edge of the text node, independent of the text height? Which anchors or positioning keys should be used in TikZ to achieve reliable top alignment in this situation?

I am trying to add ellipsis between b4 and bn and also between the 4th and last boxes at the end(child pointers). Hope I have included all libraries so that the MWE doesn't break. This is part of a larger document. The bn doesn't have a background properly. The dots are not there as there is no space between b4 and bn and similarly between the last and previous child pointer boxes.

Drawing this type of arrow turned out to be quite complex. I looked at the macro in this post and modified accordingly so that I get the shape I want. However, that macro only prints a single color arrow and it looks painfully difficult to modify to get what I want. Therefore, I thought that I would "emulate" the result by printing two superposed arrows, an original one and one scaled slightly so as to mimic that I have a different border color. This is what I have so far: \documentclass{standalone} \usepackage{amsmath} \usepackage{tikz} \usetikzlibrary{calc, arrows.meta, bending} \usepackage{pgfplots} \pgfplotsset{compat=1.18} \makeatletter \tikzset{ ararrow/.default={open}{open}, ararrow/.code 2 args={% \tikz@addoption{% \pgfset{tips=true}% draw tips even if the path isn't. \pgfgetpath\currentpath \pgfprocessround{\currentpath}{\currentpath}% \pgf@decorate@parsesoftpath{\currentpath}{\currentpath}% \pgfsetarrowsstart{% Triangle[bend, length=1.*(\pgf@decorate@totalpathlength), width =0.08*(\pgf@decorate@totalpathlength), % <-- added line join=round,#1] } \pgfsetarrowsend{% Stealth[ angle'=60, length=0.22*(\pgf@decorate@totalpathlength), width =0.26*(\pgf@decorate@totalpathlength), line join=round,#2]}% \tikz@mode@drawfalse % disable drawing of path } }, ararrow **/.style={ararrow={}{}}, ararrow oo/.style={ararrow={open}{open}}, ararrow *o/.style={ararrow={}{open}}, ararrow o*/.style={ararrow={open}{}}, } \makeatother \begin{document} \begin{tikzpicture} \coordinate (P) at (0,0); \coordinate (Q) at (1,1); \coordinate (C) at ($(P)!0.5!(Q)$); % outer arrow \draw[blue, ararrow **] (P) to[bend left=45] (Q); % inner arrow: same curve, scaled about C \begin{scope}[ shift={(C)}, scale=0.9, shift={($-1*(C)$)} ] \draw[yellow, ararrow **] (P) to[bend left=45] (Q); \end{scope} \end{tikzpicture} \end{document} which produces the image you see. Ideally, it would be great if the macro can be modified to get what I need so the user can simply type: \draw[draw=blue, fill=yellow, ararrow **] (P) to[bend left=45] (Q);

How to return an array from a command? or rather How to expand a command to some generated array? The code below generates the correct array into \OutArray inside \Transmogrifier, but I don't know how to return it to calling \ResultArray. I know one option to access the values is to define an empty array, give the array as an argument to the command, have the command generate the elements to that array and access them when the command is finished. This is not what I am looking for. My question is more to expand my understanding and increase the tools I have in my disposal. \documentclass[tikz]{standalone} \begin{document} \newcommand*{\SomeOperation}[2]{% \fpeval{#1*#2}% }% \newcommand*{\Transmogrifier}[2]{% \pgfmathparse{dim(#1)}% or \pgfmathdim{#1}% \edef\ArrayLength{\pgfmathresult}% \xdef\OutArray{{}}% \foreach \i in {0,...,\fpeval{\ArrayLength-1}}% {% \pgfmathparse{array({#1},\i)}% or \pgfmatharray{{#1}}{\i}% \ifnum \i=0% \xdef\OutArray{\SomeOperation{\pgfmathresult}{#2}}% \else% \xdef\OutArray{\OutArray,\SomeOperation{\pgfmathresult}{#2}}% \fi% }% \xdef\OutArray{{\OutArray}}% How to "return" \OutArray? %\typeout{OutArray: \OutArray}% }% \begin{tikzpicture} \def\TestArray{{1,2,3}}% \typeout{TestArray: \TestArray}% \newcommand*{\ResultArray}{% \Transmogrifier{\TestArray}{2}% }% %\ResultArray% Temp for testing \typeout{ResultArray: \ResultArray}% \end{tikzpicture} \end{document} Desired outcome in the log file: TestArray: {1,2,3} ResultArray: {2,4,6}

I encounter a confusing problem when deal with the projection of the function figure as below. I wonder how to modify my tex code's definition of \newcommand{\ShowIntersectionsAndVerticalLine} with 4 arguments: name path global1 name path global2 the color of the intersection the notation of the x-axis (as in the figure x_1 x'_1 etc.). I found similar brilliant answer as below, but they didn't fit my case. Intersection -| of a named and a calculated coordinate TiKz-pgf: Project intersection points in the abscissa axis What I want to get is shown below: Here below is my MWE of the problem. \documentclass{standalone} \usepackage{tikz} \usepackage{pgfplots} \usetikzlibrary{intersections} \usetikzlibrary{math} \usepackage{amsmath} \tikzset{elegant/.style={smooth,thick,samples=50}} % Define this as a command to ensure that it is same in both cases \newcommand*{\ShowIntersection}[3]{ \fill [name intersections={of=#1 and #2, name=i, total=\t}] [#3, opacity=1, every node/.style={above left, black, opacity=1}] \foreach \s in {1,...,\t}{(i-\s) circle (1pt)}; } \begin{document} \begin{tikzpicture} \begin{axis}[ axis x line = middle, axis y line = middle, xmin = -1, xmax = 4, ymin = -1, ymax = 3 ] \addplot[elegant,domain=-4:4,name path global=A]{(x-1)*ln(x)-x+1} node [left=2pt] {$f(x)$}; \addplot[blue,mark=*,mark size=1pt] coordinates {(1,0)}; \addplot[blue,mark=*,mark size=1pt] coordinates {(e,0)}; \addplot[blue,thick,name path global=B]{-x+1}; \addplot[blue,thick,name path global=C]{(1-1/e)*x-e+1}; \addplot[orange,thick,name path global=D] coordinates {(-1,0.5) (4,0.5)}; \ShowIntersection{A}{D}{orange} \ShowIntersection{B}{D}{blue} \ShowIntersection{C}{D}{blue} %% TBC \end{axis} \end{tikzpicture} \end{document}

I tried to use TikZ-Feynman package to plot Feynman diagram as shown in here. I used: \documentclass{article} \usepackage{tikz} \usepackage[compat=1.0.0]{tikz-feynman} \begin{document} \feynmandiagram [horizontal=a to b] { i1 -- [fermion] a -- [fermion] i2, a -- [photon] b, f1 -- [fermion] b -- [fermion] f2, }; \end{document} it should give me but I got: what is the problem?

I am writing some notes about ribbon categories and ribbon graphs and I would need to reproduce some diagrams like the ones on the figures. Does anyone know an efficient way to do it ? I have no idea so I would have to learn from scratch. Maybe an external software allowing me to export images would also be a good idea. Thanks in advance.

I would like to achieve two goals with the code below. Change the width of the red rectangle. Draw the arrows added by hand in the following screenshot. Any clue or advice will be appreciated. \documentclass{article} \usepackage{nicematrix} \usepackage{tikz} \begin{document} $\begin{NiceArray}{rcl}[name=test] 2 x + 3 & = & 5 x - 4 \\[-.5em] \\ \Block[draw=red]{1-3}{- 3} \\ \\[-.5em] 2 x & = & 5 x - 7 \\[-.5em] \\ \Block[draw=red]{1-3}{- 5x} \\ \\[-.5em] -3 x & = & - 7 \end{NiceArray}$ \end{document}

I'm a beginner with LaTeX and i have insert graph, with a csv file and pfgplots But how can i have the title of the graph in the list of figures. Thank you \begin{center} \begin{tikzpicture} \begin{axis}[% title={$U=E-R\cdot I$ représentation graphique}, no markers, xmin=0, xmax=10, ymin=12, ymax=14, ] \draw[<->,thin] (axis cs:9, 12.5625) -- (axis cs:9, 13); \draw[<->,thin] (axis cs:0, 13.125) -- (axis cs:9, 13.125); \node at (axis cs:9.5,12.784){$\Delta U$}; \node [above] at (axis cs:4.5,13.125){$\Delta I$}; \draw [-,semithick,red] (axis cs:0, 13) -- (axis cs:10, 13); \draw [<-,semithick] (axis cs: 4,12.8) -- (axis cs:4,12.75); \draw [->,semithick] (axis cs: 4,12.75) -- (axis cs:5,12.75); \node [below] at (axis cs:4.5,12.75){$\dfrac{dU(I)}{dI}=-R$}; \addplot table [x=I, y=U, col sep=comma] {test.csv}; \end{axis} \end{tikzpicture} \end{center}

The following: \documentclass[12pt]{article} \usepackage{tikz} \usetikzlibrary{graphs, graphs.standard, quotes} \begin{document} \begin{tikzpicture} \graph[grid placement, n = 4, chain shift = {(2,0)}, group shift = {(0,-2)}, math nodes, nodes = {circle, draw, thick}, edges={very thick}] { %subgraph I_n[V={s_1, s_2, s_3, s_4}], s_1["$P,Q$" left], s_2["$P, \neg Q$" right], s_3["$\neg P, Q$" left], s_4["$\neg P, \neg Q$" right], s_1 -> s_3, s_4 -> s_2, s_3 -> {s_3[>loop below], s_4}, s_2 -> {s_2[>loop above], s_1} }; \end{tikzpicture} \end{document} Works and does what it is supposed to do. However, if I uncomment the subgraph I_n, I end up with numerous errors like this: Missing \endcsname inserted. } While the same visual output is produced anyways. So, for whatever reason, specifying node labels using quotes on referenced nodes causes issues. I could however trace down the cause further. The following: \graph[grid placement, n = 4, chain shift = {(2,0)}, group shift = {(0,-2)}, math nodes, nodes = {circle, draw, thick}, edges={very thick}] { subgraph I_n[V={s_1, s_2, s_3, s_4}], s_1["$P,Q$" left], s_2["Some Label" right], s_3["Label" left], s_4["$0^0$" right], s_1 -> s_3, s_4 -> s_2, s_3 -> {s_3[>loop below], s_4}, s_2 -> {s_2[>loop above], s_1} }; Does work. The problem seems to only occur when commands are used inside quotes labels on referenced nodes. And yes, even with non-math commands, I checked that, too. After further reading of the documentation, I realised that what I am doing shouldn't even be working, as I have , in the quotes, which would have to be surrounded by {}. And, it does not work if used in a normal \node like this. This is weird in itself, as what is clearly wrong is working, at least partially. However, this: \graph[grid placement, n = 4, chain shift = {(2,0)}, group shift = {(0,-2)}, math nodes, nodes = {circle, draw, thick}, edges={very thick}] { subgraph I_n[V={s_1, s_2, s_3, s_4}], s_1["{$P,Q$}" left], s_2["{$P, \neg Q$}" right], s_3["{$\neg P, Q$}" left], s_4["{$\neg P, \neg Q$}" right], s_1 -> s_3, s_4 -> s_2, s_3 -> {s_3[>loop below], s_4}, s_2 -> {s_2[>loop above], s_1} }; Will still not work. You might be wondering why this is a problem, as my first example shows the solution. However, this is no real solution. Imagine you are creating a large graph, and then you might want to use something like subgraph I_n for this, and then label just one of these nodes. But you can't do that, because it won't work. An actual solution would be something like this: \node["{$P, \neg Q$}" right] at (s_2) {}; or \node[circle, "{$P, \neg Q$}" right] at (s_2) {}; But for this example, in both cases, the label will be too close. So something like this: \node[anchor=west, xshift=12pt] at (s_2) {$P, \neg Q$}; Is the better way it seems. Now I talked a lot around the bush. My question is: Can anybody explain why this weird behaviour happens? I imagine that the reason will be related to the graph parsing. And: Can it actually be solved somehow, without any of the workarounds (so, with actually using the quotes label syntax inside the graph and on referenced nodes)? Edit: \graph[grid placement, n = 4, chain shift = {(2,0)}, group shift = {(0,-2)}, math nodes, nodes = {circle, draw, thick}, edges={very thick}] { s_1["{$P,Q$}" left], s_2["{$P, \neg Q$}" right], s_3["{$\neg P, Q$}" left], s_4["{$\neg P, \neg Q$}" right], subgraph I_n[V={s_1, s_2, s_3, s_4}], s_1 -> s_3, s_4 -> s_2, s_3 -> {s_3[>loop below], s_4}, s_2 -> {s_2[>loop above], s_1} }; This is another way of solving the issue, but my question concerning referenced nodes still remains.

I am trying to use tikz-cd package to draw circular chemical reaction cascade. Here is what I have tried so far \documentclass{article} \usepackage{graphicx, tikz-cd} \begin{document} \begin{figure}[h] \centering \begin{tikzpicture}[node distance=3cm] % nodes \node (origin) at (0,0) {}; \node (a) at (4,0) {A}; \node (b) at (2.828,2.828) {B}; \node (c) at (0,4) {C}; \node (d) at (-2.828,2.828) {D}; \node (e) at (-4, 0) {E}; \node (f) at (-2.828,-2.828) {F}; \node (g) at (0,-4) {G}; \node (h) at (2.828, -2.828) {H}; \draw (0, 0) circle [radius = 4cm]; %This element for illustration \draw [->] (a) to[bend right=45] (b); \draw [->] (b) to[bend right=45] (c); \draw [->] (c) to[bend right=45] (d); \draw [->] (d) to[bend right=45] (e); \draw [->] (e) to[bend right=45] (f); \draw [->] (f) to[bend right=45] (g); \draw [->] (g) to[bend right=45] (h); \draw [->] (h) to[bend right=45] (a); \end{tikzpicture} \caption{Caption} \end{figure} \end{document} Which results into something like following, However, I want arrows to be in circular manner. (Aligned to circle which I have drawn for illustration purpose). Also finally I am trying to get reaction cascade like this, Any help will be appreciated !

Are there any WYSIWYG editors for PGF/TikZ? Perhaps something similar to LyX but for PGF/TikZ? If there is no WYSIWYG editor for this tandem, is there one perhaps that allows the user to easily generate PGF/TikZ templates? Alternatively, how can I most easily generate PGF/TikZ code from a visual conception? Do people mostly code their PGF/TikZ graphics from scratch?
