TikZ

I am trying to create a worksheet layout in LaTeX where one column of a table contains a writing area with a grid (like squared paper), while the other column contains several questions (Here is an example with just one question). \documentclass{article} \usepackage{array} \usepackage{xcolor} \usepackage{geometry} % \usepackage{arydshln} \usepackage{lipsum} \geometry{a4paper, left=0.35in, right=-0.1in, top=0.6in, bottom=0.4in} \definecolor{burgundy}{HTML}{8B2252} \usepackage{scrlayer-scrpage} \usepackage{tikz} \newcommand*\Circled[1]{\tikz[baseline=(char.base)]{\textcolor{burgundy}{\node[shape=circle,draw,inner sep=2pt] (char) {#1};}}} \usepackage{tikzducks} \usetikzlibrary{calc} \newcommand{\pageframe}{% \begin{tikzpicture}[remember picture, overlay] \fill [burgundy!80!white] (current page.north west) rectangle (current page.south east); \fill [white, rounded corners=1cm] ($(current page.north west)+(0.5cm,-1cm)$) rectangle ($(current page.south east)+(-0.5cm,1cm)$); \node [align=center] at ($(current page.north)+(0,-0.6cm)$) {$\color{white}\mathrm{Chapitre \ 2 - Diffusion \ thermique}$}; \node [align=center] at ($(current page.south)+(0,1.9cm)$) {\centering\begin{tikzpicture}[scale=0.5] \shuffleducks \duck[\randomhead,\randomaccessories, /tikz/nodes={scale/.evaluated={\value{page}>99?0.4:0.6},font=\bfseries}, signpost=\scalebox{1.6}{ \parbox{6cm}{\hspace{-0.4em}\color{black} \centering\thepage}}, signback =white] \end{tikzpicture}}; %%% Background grid \draw[step=5mm, gray!30, very thin] ($(current page.north west)+(7cm,-1.5cm)$) grid ($(current page.south east)+(-1cm,5cm)$); \end{tikzpicture} } \cehead[\pageframe]{\pageframe} \cohead[\pageframe]{\pageframe} \pagestyle{scrheadings} % Another try \usepackage{makecell} \newcommand{\gridcell}[1][4cm]{% \begin{tikzpicture} \draw[step=5mm, gray!40, very thin] (0,-0.2) grid (\linewidth, #1); \end{tikzpicture}% } \begin{document} \renewcommand{\arraystretch}{6} \begin{tabular}{>{\centering\raggedright}m{0.25\textwidth}||>{\centering\arraybackslash}m{0.60\textwidth}} \Circled{1} \'Enoncer le théorème de Green-Ostrograski & \\ \hline \end{tabular} \end{document} Goal I would like the second column of the table to contain a grid background (like graph paper) so that students can write their answers. I want to find the best way to create a grid (squared background) that is confined to a specific table column, and that does not overflow outside the table. What I tried so far Using a page-wide background grid, but it overflows outside the table and does not align with the table structure \draw[step=5mm, gray!30, very thin] ($(current page.north west)+(7cm,-1.5cm)$) grid ($(current page.south east)+(-1cm,5cm)$); \end{tikzpicture} The code looks like this: Drawing a grid with TikZ inside a cell → does not scale correctly with row height \newcommand{\gridcell}[1][4cm]{% \begin{tikzpicture} \draw[step=5mm, gray!40, very thin] (0,-0.2) grid (\linewidth, #1); \end{tikzpicture}% }

I'm trying to draw a 3D panel, within each panel there are dashed panel frame, some circles, lines connecting the circles, text, and maybe other objects. I tried to draw all these within a scope, then apply a projection so that all of these drawings can be 3D-rotated, but this trick only works on the panel frame, not properly on the other objects, see the screenshot: And here is the standalone tex code: \documentclass[tikz,border=6pt]{standalone} \usepackage{xcolor} \usetikzlibrary{arrows.meta,calc} % Example colors \definecolor{Accent}{RGB}{60,90,150} \definecolor{PersistCol}{RGB}{70,130,90} \definecolor{ReactCol}{RGB}{180,110,60} \definecolor{NewCol}{RGB}{180,70,80} \begin{document} \begin{tikzpicture}[ font=\small, >=Latex, side layer projection/.style={x={(0.46cm,0.25cm)}, y={(0cm,0.75cm)}}, frame/.style={ draw=black!78, dashed, line width=.72pt, dash pattern=on 5pt off 4pt, line cap=round }, v/.style={ circle, draw=gray!55, fill=gray!22, minimum size=4pt, inner sep=0pt }, pe/.style={draw=PersistCol, line width=1.0pt}, re/.style={draw=ReactCol, line width=1.0pt}, ne/.style={draw=NewCol, line width=1.0pt} ] \def\P{1.10} \newcommand{\PlaneFrame}{% \draw[frame] (-\P,-\P)--(\P,-\P)--(\P,\P)--(-\P,\P)--cycle; } \newcommand{\PlaneLabel}[1]{% \path (-.86,-\P)--(.86,-\P) node[midway, below=2pt, sloped, transform shape, font=\scriptsize] {#1}; } \newcommand{\PoolNodes}{% \node[v] (a) at (-.75,.55) {}; \node[v] (b) at (-.10,.88) {}; \node[v] (c) at (.68,.42) {}; \node[v] (d) at (-.70,-.55) {}; \node[v] (e) at (.65,-.55) {}; } % One projected layer only \begin{scope}[side layer projection] \PlaneFrame \PlaneLabel{selected \(E_t^\star\)} \PoolNodes \draw[pe] (a)--(b); \draw[re] (d)--(e); \draw[ne] (c)--(e); \end{scope} \end{tikzpicture} \end{document} What I did wrong here? UPDATE: Just tried to add \usetikzlibrary{3d} and use something like \begin{scope}[canvas is zy plane at x=0, every node/.style={transform shape}]. This only solve the issue in text and circles, not the edges (straight lines):

I have a weird problem with arrow heads at the end of plots, where they look wrong, as you can see in the picture (look below left; the line seems to exceed the arrow tip). Removing colour or changing thickness did not solve the problem. Interestingly, making the arrow longer does fix the issue, but is not a plausible fix. Also increasing the scale seems to hide the issue, but I would not like to do that, as diagrams would get too big. This issue does not appear with the longer parabola or the blue line which I drew normally. Here is an MWE. \documentclass[10pt]{book} \usepackage{tikz} \usetikzlibrary{arrows.meta} % Tikz libraries \tikzset{>={Stealth}} \begin{document} \begin{tikzpicture}[scale=0.4] \draw[->, thick, red, domain=-1:3.5, variable=\t, smooth, samples=75] plot ({\t,2-0.5*\t*\t}); \draw[<-, thick, red, domain=-2:-0.5, variable=\t, smooth, samples=75] plot (2*\t,\t-1); \draw[draw=red, fill=white] (-1,-1.5) circle (4pt); \draw[thick, blue,<->] (0,-3) -- (1,-2); \draw[red, fill] (-1,1.5) circle (4pt); \end{tikzpicture} \end{document} Any idea what is going wrong? And how to fix it? Zoomed in picture on the issue:

What I tried to replicate is something as below: Noted that the double-dotted is aligned as the red line denoted, and the "rotated box" is NOT what I want(just because the image I get rotated itself), I just want something the same as \dashbox or \doublebox, the normal horizonal box. The post here, I think, just want to focus the dots alignment. Now I have the following code: \documentclass{article} \usepackage[most]{tcolorbox} \usepackage{tikz} \usepackage{lipsum} \usepackage{dashbox} \usepackage{fancybox} % https://tex.stackexchange.com/a/101263/322482 \makeatletter \tikzset{ dot diameter/.store in=\dot@diameter, dot diameter=3pt, dot spacing/.store in=\dot@spacing, dot spacing=10pt, dots/.style={ line width=\dot@diameter, line cap=round, dash pattern=on 0pt off \dot@spacing }, } \tcbset{ doubledotted/.style={ empty, sharp corners, frame engine=path, frame empty, frame code={ \draw[dots](frame.south west) rectangle (frame.north east); \draw[dots]([xshift=-\dot@spacing,yshift=-\dot@spacing]frame.south west) rectangle ([xshift=\dot@spacing,yshift=\dot@spacing]frame.north east); }, } } \makeatother \begin{document} AAA \qquad\tcbox[doubledotted,nobeforeafter,box align=center]{This is a tcolorbox.}\qquad BBB \vspace{1cm} \begin{tcolorbox}[doubledotted] \lipsum[2] \end{tcolorbox} \bigskip \fbox{This is a framebox.} \dashbox{This is a dashed framebox.} \doublebox{This is a doublebox.} \end{document} which gives: The disturbing point is that the dotted in a \path is hard to control the alignment precisely. I have to cliam that, I think that would be two different approach to achieved this: One with tcolorbox and tikz Another with some "plain" approaches for example dashedbox and fancybox: fancybox.sty:

I recently noticed a bug, where the TikZ backgrounds library ignores any other options applied within the same scope definition. As you can see in the MWE below, I have a scope on the background layer with the additional options blue and ultra thick, which are ignored. \documentclass{standalone} \usepackage{tikz} \usetikzlibrary{backgrounds} \begin{document} \begin{tikzpicture} \draw[red, ultra thick] (0,0) -- (2,0); \begin{scope}[on background layer,blue,ultra thick] \draw (1,-1) -- (1,1); \end{scope} \end{tikzpicture} \end{document} Using nested scopes or defining the options directly in the path definition gives the desired result. \documentclass{standalone} \usepackage{tikz} \usetikzlibrary{backgrounds} \begin{document} \begin{tikzpicture} \draw[red, ultra thick] (0,0) -- (2,0); \begin{scope}[on background layer] \begin{scope}[blue,ultra thick] \draw (1,-1) -- (1,1); \end{scope} \end{scope} \end{tikzpicture} \end{document} Is this a bug? It isn't mentioned in the manual. I couldn't find a git repo to report an issue, so I hope this is the right place to ask.

I have two rectangular TikZ nodes placed one below the other: B1 is above B2. I would like to create a third rectangular node B3, shifted to the right in the x-direction, such that: the top of B3 is aligned with B1.north the bottom of B3 is aligned with B2.south I am not sure what is the best TikZ way to do this cleanly. Here is a minimal example of the situation: \documentclass{standalone} \usepackage{tikz} \usetikzlibrary{calc} \begin{document} \tikzstyle{block} = [draw, fill=white, rectangle, inner xsep=0pt, align=center, font=\small]% \begin{tikzpicture} \node [block, text width=3em] (B1) {Block 1}; \node [block, anchor=north, text width=3em] (B2) at ([yshift=-5em]B1.south) {Block 2}; \node [block, anchor=west] (B3) at ([xshift=5em]$(B1.east)!0.5!(B2.east)$) {Block 3}; \end{tikzpicture} \end{document} I tried using minimum height with coordinate differences, but I could not make it work properly. What is the recommended approach?

How to make rounded corner and curve (..controls?) for this path (or similar)? \documentclass[margin={1.5cm 1,5cm 1.5cm 1.5cm}]{standalone} \usepackage{tikz} \begin{document} \begin{tikzpicture} \fill[cyan] (0,0)--(2,0)--(5,2)--(7,3)--(6,4)--(4,7)--(2,7)--(.5,5)--(0,2)--cycle; \end{tikzpicture} \end{document}

Muzimuzhi has extended the dim feature in tkz-euclide here: However, not all the segments are long enough to label distance "inside", in some case, I need the following "invert"-dim feature: \documentclass[border=5pt]{standalone} \usepackage{tkz-euclide} \usepackage{fourier} \begin{document} \begin{tikzpicture} \tkzDefPoints{0/0/O,3/0/A,1/1/A2,.5/2/C2} \tkzDefRectangle(A2,C2)\tkzGetPoints{B2}{D2} \tkzDrawPolygon[thick,black,fill=yellow!50](A2,B2,C2,D2) \tkzLabelSegment[below](A2,B2){$t$} \draw[thick](A2) --+(0,-.5cm) ++(0,-.25cm) coordinate(tmpA) (B2) --+(0,-.5cm) ++(0,-.25cm) coordinate(tmpB); \draw[thick,latex-] (tmpB) -- +(-.4cm,0); \draw[thick,latex-] (tmpA) -- +(.4cm,0); %%%%%%%%%%%%%% \tkzDrawSegment[thick,dim style/.append style={red,dash pattern={on 2pt off 2pt}},dim={$a$,-.5cm,inner xsep=3pt}](O,A) %%%%%%%%%%%%%% \end{tikzpicture} \end{document} I have not quite familiar with pgf macros, I wonder whether that is possible to learn from muzimuzhi's code to support the "invert"-dim feature, to label these kind of segments distance from the two-side inwards more elegantly?

This is my full work: \documentclass[tikz,border=1pt]{standalone} \usepackage{tikz} \usepackage{calligra} \usepackage[T1]{fontenc} \begin{document} \begin{tikzpicture}[line width=1pt] \path[use as bounding box] (-5.6,-1.2) rectangle (6.4,7.2); % Circle \draw (2.6,3.0) circle (3.1); % Secant line P-T-U \draw (-5.0,0.1) -- (4.7,5.6); % Chords \draw (2.6,2.3) -- (1.2,1.7); % short chord near S \draw (1.2,1.7) -- (4.0,1.4); % S to V \draw (4.0,1.4) -- (4.7,5.6); % V to U % Angle at S \draw (1.2,1.7) ++(0.55,0) arc[start angle=0,end angle=123,radius=0.55]; % Angle at V \draw (4.0,1.4) ++(-0.55,0) arc[start angle=180,end angle=95,radius=0.55]; % Labels \node[font=\fontsize{34}{34}\selectfont] at (-5.0,-0.4) {$P$}; \node[font=\fontsize{34}{34}\selectfont] at (0.2,2.9) {$T$}; \node[font=\fontsize{34}{34}\selectfont] at (5.2,5.9) {$U$}; \node[font=\fontsize{34}{34}\selectfont] at (4.3,0.4) {$V$}; \node[font=\fontsize{34}{34}\selectfont] at (0.9,0.7) {$S$}; % Angle labels \node[font=\fontsize{28}{28}\selectfont] at (2.0,2.5) {$123^\circ$}; \node[font=\fontsize{28}{28}\selectfont] at (3.6,2.0) {$85^\circ$}; \end{tikzpicture} \end{document} and this is the result: What I want: Please along with full MWE ready to copy paste, could you explain, what the trick is and what to add and where to add, so that I can also learn?

I used Mathematica and tried grid of cylinder I don’t know how to draw with other tools. How can I draw it?

I am not much better at mathematics equations, but I need to draw some graphs in latex. I tried this one but it's not look exactly the same as shown in the image. Please I will be very grateful if anyone can help regarding this. \documentclass[tikz, border=1pt]{standalone} \usetikzlibrary{arrows.meta, ext.topaths.arcthrough, decorations.markings} \usetikzlibrary{math} \usepackage{pgfplots} \pgfplotsset{compat=1.18} \begin{document} \begin{tikzpicture} \begin{axis}[ hide axis, % Hide the axis lines, labels, and ticks view={45}{45}, axis equal, grid=none, samples=50, domain=0:7*pi, ] % First helix shifted upwards \addplot3[black, smooth] ({x*cos(deg(x))}, {x*sin(deg(x))}, {x + 1}); % Second helix shifted downwards \addplot3[black, smooth] ({-x*cos(deg(x))}, {-x*sin(deg(x))}, {-x - 1}); \end{axis} \end{tikzpicture} \end{document}

I am using the TikZit application to construct a diagram containing nodes that "contain" or "consist of" only text (formatted with color, etc.) and that are connected by various edges. When inputing the text as the label argument, the connecting edge encroaches into the middle of the text, like this: Here is the source code generated by TikZit: \begin{tikzpicture} \begin{pgfonlayer}{nodelayer} \node [style=none] (0) at (-2.5, 7) {Hello world!}; \node [style=green dot] (1) at (1.75, 5) {}; \node [style=red dot] (2) at (2.25, -0.75) {}; \node [style=none] (3) at (-3, -2) {}; \end{pgfonlayer} \begin{pgfonlayer}{edgelayer} \draw (0.center) to (1); \draw [in=30, out=45, looseness=2.25] (1) to (2); \draw (3.center) to (2); \end{pgfonlayer} \end{tikzpicture} I was able to use the label={POSITION:TEXT} option to modify the default behavior \node [style=none, label={above=Hello \textcolor{blue}{World!}}] (0) at (-2.5, 7) {}; which renders which is what I am wanting. The problem is that I do not want to manually input the position parameter for each node and I do not know how to set up a node style that will automatically position the edge connection relative to the text node without having to specify the position in each case. To put it in question form: Is there a way to set up a node style that will automatically position the connecting edge on the "outside" of the node relative to the text like the second image above? Any help is appreciated.

I would like to make a double entry table in LaTeX. Here is the result that I would like to get: I found a clue here: \documentclass{article} \usepackage{multirow} \begin{document} \begin{center} \begin{tabular}{ c || l | r | c } & \multicolumn{3}{c}{Columns} \\ \hline \hline \multirow{3}{*}{Rows} & A1 & B1 & C1 \\ \cline{2-4} & A222 & B22 & C2 \\ \cline{2-4} & A3 & B333 & C33 \end{tabular} \end{center} \end{document} I managed to get a partial solution: \begin{document} \begin{center} \begin{tabular}{ l || r | c } A1 & B1 & C1 \\ \hline \hline A222 & B22 & C2 \\ \hline A3 & B333 & C33 \end{tabular} \end{center} \end{document} However, it doesn't solve all my problems. Is it possible to get square cells with everything centered in the cell? I found other partial solutions here but I don't know tikz at all. The matrix environment might not suit my needs because I would like to avoid outer borders and I didn't find any solution with double lines separing row's titles from the inner cells.

I have to draw a graph in LaTeX and I have to draw an edge from a node to a rectangle as seen here. (image description: there is a node on the left and a box on the right, with multiple straight lines going from the node to the box, all having different angles, the endpoints form a straight line) I haven't found an answer yet and would rather avoid making a ton of small edges, especially since I need to make such an edge multiple times and in different directions.

I am currently working on a layout for a document (based on this post and this), using scrbook with scrlayer-scrpage. After a long struggle to get lines with rounded corners in the header and footer, everything works as expected -- except the numbering of the table of contents in the header. For some reason that I do not understand (I am sure because lack of basic knowledge) it gets a chapter number 0 and section number 0.0, instead of an empty field, which is the desired output for unnumbered chapters. When I compile my document with the slightly modified original code for the header no numbers are given for the table of contents. Based on this, my idea was to use \ifnumbered{chapter}{THEN}{ELSE}, either by redefining \chaptermarkformat and \sectionmarkformat (IDEA 1) or by changing the output for \lehead{} (and \rohead{} IDEA 2). What am I missing? Any help is much appreciated. Thank you in advance.

I works between science and geobiology in France and I would like to create custom dowsing charts which would looks like the exemples above : Those charts are for longer text and they have to be in the axis of each portion of circle and starting from the outer side of the center for the left half center and staring from the center for the right half center to be readeable... If you have any idea for this, it could be really good ! On the left side, there is some index for dowsing from a dowsing chart to one other and a title permit to have some reference to link those chart together. Actually I am not really skilled in programming and I am a simple user of latex, so i might need help to start with this. Maybe anyone have in mind some clues / exemples to look on to get this working with TikZ. In my mind I would like to enter a list of terms, and that the TikZ script automatic split into angle angle sections with automation. Thanks a lot !

More precisely I'd like to get something like this: \begin{tikzpicture}[ % -{Stealth[length = 2.5pt]}, start chain = going right, node distance = 0pt, MyStyle/.style={draw, minimum width=1.6em, minimum height=2em, outer sep=0pt, on chain}, ] \node [MyStyle] (1) {$A$}; \node [MyStyle] (2) {$B$}; \node [MyStyle] (3) {$C$}; \node [MyStyle] (4) {$D$}; \node [MyStyle] (5) {$E$}; \node [MyStyle] (6) {$F$}; \node [MyStyle] (7) {$G$}; \node [MyStyle] (8) {$Q$}; \node [MyStyle] (9) {$B$}; \node [MyStyle] (10) {$G$}; \node [MyStyle] (11) {$A$}; \node [MyStyle] (12) {$D$}; \node [MyStyle] (13) {$W$}; \node [MyStyle] (14) {$B$}; \node [MyStyle] (15) {$n$}; \node [MyStyle] (16) {$6$}; \begin{scope}%[-{Stealth[length = 2.5pt]}] %\draw (1.north) [out=25, in=155] to (2.north); %\draw (1.north) [out=30, in=155] to (3.north); \draw (1.north) [out=35, in=155] to (4.north); \draw (1.north) [out=40, in=155, below] to (6.north); \draw (1.south) [out=40, in=155, below] to (6.south); \end{scope} %\draw[decorate,decoration={brace, amplitude=10pt, raise=5pt, mirror}] %(2.south west) to node[black,midway,below= 15pt] {$k$-elements} (7.south east);% \end{tikzpicture} This code produces the following output: Problem: Bottom arrows between items. Code is based on: proportional boxes in Tikz (array diagram)

Consider: I need to draw a pulley system as in the figure. How can I do that? \begin{tikzpicture} \fill[pattern=north east lines] (-3,0) rectangle (3,.3); \draw(-3,0)--(3,0); \draw(-2.5,0)--(-2.5,-2.4); \draw(2.5,0)--(2.5,-1); \draw[fill=white] (-2.5,-2.4) circle (.3); \draw[fill=white] (2.5,-1) circle (.3); \draw[fill=white] (0,-3) circle (.153); \draw (2.5,-1) coordinate (a) node[right] {} -- (0,-3) coordinate (b) node[left] {} -- (0,-2.75) coordinate (c) node[above right] {} pic["$\beta$", draw=orange, <->, angle eccentricity=1.2172, angle radius=.51cm] {angle=a--b--c}; \draw (0,-2.75) coordinate (a) node[right] {} -- (0,-3) coordinate (b) node[left] {} -- (-2.5,-2.4) coordinate (c) node[above right] {} pic["$\alpha$", draw=orange, <->, angle eccentricity=.72172, angle radius=.751cm] {angle=a--b--c}; \draw[dashed] (0,-3)--(0,-1); \draw[fill=white] (-2.5,-2.4) circle (.3); \draw[fill=white] (2.5,-1) circle (.3); \draw[fill=white] (0,-3) circle (.153); \end{tikzpicture}

I am trying to build the following pie chart with latex and the code below, however it seems quite difficult to match the legend, colors palette and external circle grouping colors. \documentclass[tikz,border=10pt]{standalone} \begin{document} \def\angle{0} \def\radius{3} \def\cyclelist{{"orange","blue","red","green"}} \newcount\cyclecount \cyclecount=-1 \newcount\ind \ind=-1 \begin{tikzpicture}[nodes = {font=\sffamily}] \foreach \percent/\name in { 0.01/1\% Cash, 4.26/ 5\% Miton Multi-Cap Income, 6.86/6\% Schroder Income Maximiser, 3.82/6\% Trojan Income, 3.32/7\% CF Woodford Equity Income, 2.91/7\% Artemis Global Income, 2.87/4\% First State Global Listed Infraestructure 2.63/4\% Lazard Global Listed Infraestructure 3.50/4\% Legg Mason RARE Global Income 2.55/6\% Newton Global Income 4.6/5\% Henderson Strategic Bond 5.01/4\% Invesco Perpetual Monthly Income Plus 4.4/5\% Jupiter Strategic Bond 0/4\% L&G All Stocks Index Linked Gilt Index 2.3/5\% L&G Short Dated Sterling Corporate Bond Index 5.95/4\% Royal London Short Duration Global High Yield Bond 3.55/4\% Twenty Four Corporate Bond 5.03/4\% Twenty Four Dynamic Bond 4.8/5\% F&C Property Growth & Income 4.44/5\% Aviva Multi Strategy Target Income 3.45/5\% Invesco Perpetual Global Targeted Income } { \ifx\percent\empty\else % If \percent is empty, do nothing \global\advance\cyclecount by 1 % Advance cyclecount \global\advance\ind by 1 % Advance list index \ifnum3<\cyclecount % If cyclecount is larger than list \global\cyclecount=0 % reset cyclecount and \global\ind=0 % reset list index \fi \pgfmathparse{\cyclelist[\the\ind]} % Get color from cycle list \edef\color{\pgfmathresult} % and store as \color % Draw angle and set labels \draw[fill={\color!50},draw={\color}] (0,0) -- (\angle:\radius) arc (\angle:\angle+\percent*3.6:\radius) -- cycle; \node at (\angle+0.5*\percent*3.6:0.7*\radius) {\percent\,\%}; \node[pin=\angle+0.5*\percent*3.6:\name] at (\angle+0.5*\percent*3.6:\radius) {}; \pgfmathparse{\angle+\percent*3.6} % Advance angle \xdef\angle{\pgfmathresult} % and store in \angle \fi }; \end{tikzpicture} \end{document} I found particularly complex to replicate it with latex, so any help will be welcome. Thanks for your support!

I'd like to produce these diagrams using Tikz-Feynman. What I have so far is \RequirePackage{luatex85} \documentclass{standalone} \usepackage[compat=1.1.0]{tikz-feynman} \begin{document} $\feynmandiagram [horizontal=a to b, layered layout, baseline=(i1.base)] { i1 -- a [dot] -- [photon,half left,momentum'=\(q\)] b [dot] -- [photon,half left,momentum'=\(q\)] a, b -- f1 }; + \feynmandiagram [horizontal=a to b, layered layout, baseline=(a.base)] { {i1,i2} -- a [dot] -- [photon,half left,momentum'=\(q\)] b [crossed dot] -- [photon,half left,momentum'=\(q\)] a, };$ \end{document} There are a few open questions: How can I move the momentum arrows outside the loops? How can I shorten the in and outgoing lines? How can I precisely vertically align the center of both diagrams with the plus sign? How can I add the crossed dot on the first diagram? Update With the help of JP-Ellis I was able to get \RequirePackage{luatex85} \documentclass{standalone} \usepackage[compat=1.1.0]{tikz-feynman} \begin{document} $\feynmandiagram [horizontal=a to c,inline=(a.base)] { a [dot] -- [charged boson,quarter left,edge label=\(q\)] b -- [photon,quarter left] c [dot] -- [charged boson,quarter left,edge label=\(q\)] d [crossed dot] -- [charged boson,quarter left,edge label=\(q\)] a, f1 -- c, i1 -- a, }; \quad\raisebox{-0.5ex}{+}\quad \feynmandiagram [horizontal=a to b, layered layout, inline=(a.base)] { {i1,i2} -- a [dot] -- [charged boson,half left,edge label=\(q\)] b [crossed dot] -- [charged boson,half left,edge label=\(q\)] a [desired at={(0, 0)}], };$ \end{document} One question remains: is there a way to move the arrow on charged boson and its edge label to the end of a line? My intent is to to have them at the top of the upper arch in the first diagram (rather than in the middle of the first quarter).

I would like to have a circle where the circumference is coloured with three different colours, something like the following but a line and with only three colours: I initially tried \documentclass{article} \usepackage{amsmath} \usepackage{tikz} \pagestyle{empty} \begin{document} \begin{tikzpicture} \draw [red] (0,0) arc [radius=1, start angle=0, end angle=120]; \draw [green] (1,0) arc [radius=1, start angle=120, end angle=240]; \draw [blue] (0,0) arc [radius=1, start angle=240, end angle=360]; \end{tikzpicture} \end{document} but this does not give the right result, and the arguments of the function are such that it's quite difficult to make what I have in mind.

How can I align text along the circumference of a circle like this using TikZ? Please ignore the icons. I tried using paths and decorations, but I don't know how to constrain the text to each sector. This is the code I used to draw the circles and the sectors \begin{tikzpicture} \draw[thick] (0cm,0cm) circle(3cm); \foreach \x in {0,45,...,360} { % lines from center to point \draw[black] (0cm,0cm) -- (\x:3cm); } \end{tikzpicture}

I was quite impressed by the figures generated by TikZ and wanted to try TikZ to generate a few figures (please see the attached image drawn using an external WYSWYG program). When I tried to reproduce the figures myself using TikZ I found it very difficult to control the shapes in required positions. What is the simplest method to draw!these figures using TikZ?

I have gotten some undesirable behavior with PGF/TikZ related to clipping and drawing paths with different color, say gray. So I tried with no success to exchange between \clip[draw=gray], \draw[clip,gray] or \path[draw=gray, clip] or maybe using indirectly styles, the Emacs' output throws a TeX error message: Extra options not allowed for clipping path command... the only way to do so is by using scopes: \begin{scope}[draw=gray] ... \end{scope} Unfortunately, this technique requires that all the scoped objects' lines should be switched to black. So is there a trickery way to achieve this without passing by scope environment?

At this address Label Points in a circle in tikz you can see the code to divide a circle into x cells. How to write a phrase into each cell of the divided circle?

Update 2026: mohelper This new package comes with a webhelper. You can edit your diagrams there and insert the tex output into your projects. However (!), please view the repo and read the manual (you can find it on ctan or from the repo). This question led to a new package: modiagram I'm wondering if anyone has seen a package for drawing (qualitative) molecular orbital splitting diagrams in LaTeX? Or if there exist any packages that can be easily re-purposed to this task? Otherwise, I think I'll have a go at it in TikZ. Example (Cropped from a graphic on Wikipedia by 'orci' - I suspect it was drawn manually due to the slight misalignment of various elements) Having a go at it in TikZ I decided to try doing this in TikZ and have prepared a MO diagram for dioxygen (prior attempt at much simpler dihydrogen below) - this is the kind of scheme I'm going for. There are at least three problems with this approach: It's not very general and I don't know any strategies to make it arbitrarily extensible (e.g. stacking energy levels etc like in the example diagram.) Partially addressed The H, H_{2} labels are not aligned at the baseline of each H, so the H_{2} is slightly higher than the other two. Solved, thanks @Matthew Leingang The coordinates, whilst text-proportionate, are all hard coded and I would like to know how to make this diagram scalable in terms of a total width, total height and separation of the split levels. Addressed using (probably too many) variables and in-coordinate calculation Please help me improve this probably pretty naive approach. Specification MO diagrams can be drawn in a variety of different ways. In the simplest case, such as for either O2 or H2 here, the left column represents the orbitals of one atom as horizontal lines, arranged vertically in order of their relative energies. The right column does the same for the other atom. In this case the example picture represents orbitals as boxes for clarity as several orbitals can have the same energy, which is what occurs in the case of the 3x 2p orbitals and the pi_x, pi_y orbitals. In this situation they are shown side by side. Orbitals may have zero, one or two (antiparallel) electrons. It is fairly common to simply see orbitals represented as horizontal lines rather than boxes. Lines connect the orbitals to indicate the contribution of the atomic orbitals to a molecular orbital. The center column shows the molecular orbitals generated from the combination of the atomic orbitals, which can either be additive (in which case the relative energy drops, giving a bonding orbital) or subtractive (in which case the relative energy increases with respect to the atomic orbitals, i.e. an antibonding orbital). As this diagram is qualitative only, the splitting can be treated as symmetric.
