TikZ

Deformed and undeformed configurations of the beam Hello everyone, I am trying to reproduce this image using LaTeX TikZ. I have written the code below, but I am encountering difficulties when drawing the curved line through the thickness (the yellow line). Any suggestions would be greatly appreciated. \documentclass[tikz,border=5mm]{standalone} \usepackage{tikz} \usetikzlibrary{arrows.meta, decorations.pathmorphing, positioning, calc} \begin{document} \begin{tikzpicture}[>=Stealth, scale=1.5] % Styles \tikzset{ zigzag/.style={decoration={zigzag, segment length=2mm, amplitude=1mm}, decorate}, break/.style={decoration={zigzag, segment length=4mm, amplitude=2mm}, decorate}, dot/.style={circle, fill=black, inner sep=1.2pt}, hollowdot/.style={circle, draw=black, fill=white, inner sep=1.2pt} } % --- Undeformed Beam (Top Part) --- \begin{scope}[shift={(0,2.5)}] % Beam edges \draw (-1.5, 0.4) -- (2, 0.4); \draw (-1.5, -0.4) -- (2, -0.4); \draw [zigzag] (-1.5, -0.4) -- (-1.5, 0.4); \draw [zigzag] (2, -0.4) -- (2, 0.4); % Neutral axis \draw [dotted, thick] (-1.5, 0) -- (2.5, 0) node[right] {$x, u$}; \draw [->] (2.3, 0) -- (2.7, 0); % Center vertical line and z-axis indicator \draw (0, 0.4) -- (0, -0.4); \node [hollowdot] at (0,0) {}; \draw [->] (0.2, 0) -- (0.2, -0.3); \node [right, font=\small] at (0.2, -0.15) {$z$}; % Left coordinate system and x-dimension \draw (-2.8, 0) -- (-2.3, 0); \draw [break] (-2.3, 0) -- (-1.9, 0); \draw (-1.9, 0) -- (-1.5, 0); \draw (-2.8, 0) -- (-2.8, -0.8) node[below, font=\small] {$z, w$}; \draw [->] (-2.8, -0.6) -- (-2.8, -1); \draw [->] (-2.8, -0.6) -- (0, -0.6); \node [fill=white, inner sep=1pt, font=\small] at (-1.4, -0.6) {$x$}; % Vertical reference line extending down \draw [thin, gray!60] (0, -0.4) -- (0, -3.5); \end{scope} % --- Deformed Beam (Bottom Part) --- \begin{scope}[shift={(0,1)}] % Curved beam boundaries \draw (-1.5, 0.4) to[bend right=15] (2, 0.4); \draw (-1.5, -0.4) to[bend right=15] (2, -0.4); \draw [zigzag] (-1.5, -0.4) -- (-1.5, 0.4); \draw [zigzag] (2, -0.4) -- (2, 0.4); \draw [dashed] (-1.8, 0) to[bend right=15] (2.3, 0); % Reference point (u0, w0) on the neutral axis \coordinate (P0) at (0.8, -0.30); \node [hollowdot] at (P0) {}; \node [below right, xshift=50pt, yshift=-20pt, font=\small] (L0) {$(u_0, w_0)$}; \draw [->, shorten >=2pt] (L0.west) -- (P0); % Vertical dashed reference line through P0 %\draw [red,dashed] ($(P0) + (0, 1.2)$) -- ($(P0) + (0, -0.5)$); \draw [red,dashed] (P0) -- ($(P0) + (115:1.0)$); % Deformed cross-section line \draw [yellow,thick] ($(P0) + (-0.3, 0.6)$) to[bend left=25] ($(P0) + (0.1, -0.6)$); % Point (u, w) on the cross-section \coordinate (P) at ($(P0) + (-0.01, -0.25)$); \node [dot] at (P) {}; \node [left, xshift=-2pt, yshift=2pt, font=\small] at (P) {$(u, w)$}; % Rotation angles at the top % Angle phi_x (rotation of the cross-section) \draw [->] ($(P0) + (0, 0.8)$) arc (90:115:0.8); \node [left, font=\small] at ($(P0) + (105:0.9)$) {$\phi_x$}; % Angle -dw0/dx (rotation of the normal) \draw [->] ($(P0) + (0, 0.8)$) arc (95:90:0.8); \node [right, xshift=6pt, font=\small] at ($(P0) + (80:0.8)$) {$-\frac{\partial w_0}{\partial x}$}; \draw [green,dashed] (P0) -- ($(P0) + (90:1.2)$); % Slope angle at the neutral axis \draw [blue,dashed] (P0) -- ($(P0) + (1.5, 0)$); \draw [yellow,dashed] ($(P0) + (-0.5, -0.1)$) -- ($(P0) + (1.3, 0.20)$); % tangent line \draw [->] ($(P0) + (1.4, 0)$) arc (0:10:1.2); \node [right, font=\small] at ($(P0) + (5:1.4)$) {$-\frac{\partial w_0}{\partial x}$}; \end{scope} \end{tikzpicture} \end{document}

When I generate diagrams with matplotlib/seaborn, I find it difficult to set up the padding and what not for it fit properly and have proper consistency across diagrams. Does anyone use this stack and get things running porperly? What I am doing now is gnerating csvs and directly doing tikz but I would like to avoid that.

What I want to achieve is something like: Noted that the "glow" here is somewhat like a "shadow" path out of the border. However, I have tried blur shadow={shadow xshift=0pt,shadow yshift=0pt,shadow scale=1.05}: \documentclass[tikz,border=5pt]{standalone} \usetikzlibrary{shadows.blur,spy} \begin{document} \begin{tikzpicture}[spy using outlines={circle, magnification=3, size=3cm}] \draw[fill=gray!25,draw,rounded corners,blur shadow={shadow xshift=0pt,shadow yshift=0pt,shadow scale=1.05}] (40:4) arc[start angle=40,end angle=140,radius=4] -- (140:2) arc[start angle=140,end angle=40,radius=2] -- cycle; \draw[fill=white] (0,2.75) -- ++(.5,-.25) -- (0,3.5) -- ++(-.5,-1) -- cycle; \spy[red] on (140:2) in node at (-2,-1); \spy[blue] on (40:2) in node at (+2,-1); \end{tikzpicture} \end{document} The shadow glow is not what I was after: Is that possible to provide the shadows for such ideal glow for irregular shape?

I have the following code: \documentclass[tikz,border=5pt]{standalone} \begin{document} \begin{tikzpicture} \draw[fill=gray!25,draw,rounded corners=8pt] (40:2) -- (40:4) arc[start angle=40,end angle=140,radius=4] (140:4) -- (140:2) arc[start angle=140,end angle=40,radius=2] (40:2) -- cycle; \end{tikzpicture} \end{document} which I think would get a rounded sector, but in fact: Any paraphase on this? Maybe related ?

I want to create a multi part parallelogram input block for a flowchart. There is no multi part trapezium shape that exist so for now I used a standard rectangular multi part shape with the xslant option to make it look like a parallelogram. I defined a style that I can easily reuse. The problem is that the text is also slanted, and if possible I would like it normal. Is there a way to apply xslant only to the shape and not to the text ? I tried creating a second node only for the text but the problem is that the paralellogram doesn't resize properly to fit the text. My MWE : \documentclass[class=article]{standalone} \usepackage[]{xcolor} \usepackage{tikz} \usetikzlibrary{shapes} \tikzstyle{io} = [rectangle split, rectangle split parts=2, xslant=0.4, draw, rectangle split part fill={blue!50,blue!20}, text centered, minimum width=4.25cm, minimum height=2cm] \begin{document} \begin{tikzpicture} \draw (0,0) node[io,name = ,align = center]{Parameters\nodepart{two} $\alpha$, $\eta$}; \end{tikzpicture} \end{document} Thanks for your help.

Is there a way to continue a path we draw using \draw with a plot, just as we do for instance also with arc or similar commands? In the example below I have a straight line, but I'd like the plot to append directly to that line, as indicated by the red dots. I can of course do that e.g. with plot[shift={(1,1)},...], but that means that I have to repeat that second coordinate in the path, which makes it again more cumbersome to use if we want to change something later (and the second straight line segment then points to the original endpoint without the shift). So this is more a question about "ergonomically" using this plot command inside other paths. E.g., I also like using the ++ syntax to precisely extend a path a certain distance horizontally, without having to repeat the previous y-coordinate, and I was wondering whether there is something similar we can do with the plot command inside such a path. \documentclass{standalone} \usepackage{tikz} \usepackage{xcolor} \usepackage{pgfplots} \pgfplotsset{compat=1.17} \usetikzlibrary{calc} \begin{document} \begin{tikzpicture}[domain=0:4] \draw[black!10!white, dashed] (0, 0) grid (4, 2); \draw (0, 1) -- (1, 1) node[left] {} plot[domain=0:1, samples=100] function{sin(6.3*x)} node[right] {} -- ++(1, 0); \end{tikzpicture} \end{document}

My question is essentially the same as this question, but I'm asking again because the answer provided is not very resilient. In particular, it doesn't work for the kind of diagram I want. I want to use Tikz to draw a diagram with lots of nodes and arrows; essentially, a flowchart. The diagram should start with a single node which is centered on the page (in the MWE below, this is the "Hello there" box). If I try to just use the \centering command, the whole picture gets centered, which is not what I want. The answer I linked above suggests using the \useasboundingbox command. However, this doesn't seem to do what I want. Here is my minimal working example: \documentclass[a4paper, 11pt]{article} \usepackage{tikz} \begin{document} This is a line of text which has been written with no purpose other than to help illustrate how the figure below appears on a page. \begin{figure}[ht] \centering \begin{tikzpicture}[rect/.style={rectangle, draw=black, thin}] \node[rect] (box1) at (0,0) {Hello there}; % Location 1 \node[rect] (box2) at (5,-1) {Hi}; % Location 2 \end{tikzpicture} \end{figure} This is a line of text which has been written with no purpose other than to help illustrate how the figure above appears on a page. \end{document} The linked answer suggests using the command \useasboundingbox (box1.south east) rectangle (box1.north west);. If I put this command at location 2, then the bounding box includes both boxes "Hello there" and "Hi", and the box "Hello there" is not centered (see below). If I put this command at location 1, then the bounding box only includes the "Hello there" box; this centers it the way I want, but then the box "Hi" ends up overlapping with the text below (see below). How can I make the "Hello there" box be centered on the page?

I have some lua code that generates coordinates of many triangles/quadrilaterals I then want to draw/fill. See this answer about Penrose tilings for a concrete example. The drawing is actually done in TikZ via the luadraw package, but I am wondering if I can make the code faster by replacing TikZ with l3draw. Rewriting my actual code to remove TikZ and luadraw dependences (and use l3draw or any other drawing tool) is not a complex task, but will ask me some time due to my limited programming skills. So I would prefer to know in advance if this is a good idea or not. Apart possibly performance, is there any other reasons to use l3draw over pgf for this kind of task? Edit: I am not using TikZ/pgf for the rest of the document. Suggesting to use another environment (as picture) is a valid answer.

I should create a drawing that illustrates this domain in 3D: T= \{(x, y, z) \in \mathbb{R}^3\colon x^2 +y^2\leq (z-9)^2, 0\leq z\leq 3 \}. It is a double cone with vertex at (0,0,3) if it were x^2 +y^2= (z-9)^2. I may have to change the scale but I don’t want the drawing to look worse. How can I colour the two-sloped cone part that satisfies the inequality x^2 +y^2\leq (z-9)^2? ...and then adding 0\leq z\leq 3? \documentclass{article} \usepackage{tikz} \usetikzlibrary{patterns} \usepackage{tikz-3dplot} \usepackage[active,tightpage]{preview} \PreviewEnvironment{tikzpicture} \setlength\PreviewBorder{2pt} \begin{document} \tdplotsetmaincoords{60}{110} \begin{tikzpicture}[tdplot_main_coords,scale=0.9] \pgfmathsetmacro{\tini}{0.5*pi} \pgfmathsetmacro{\tfin}{1.85*pi} \pgfmathsetmacro{\tend}{2.5*pi} \def\h{10.2} \draw[thick,->] (0,0,0) -- (3.5,0,0) node[below left] {$x$}; \draw[dashed] (0,0,0) -- (-2.5,0,0); \draw[thick,->] (0,0,0) -- (0,3.5,0) node[right] {$y$}; \draw[dashed] (0,0,0) -- (0,-2.5,0); \draw[thick,->] (0,0,0) -- (0,0,12) node[above] {$z$}; \fill (0,0,9) circle (1pt); \node[right] at (0,0,9) {$(0,0,9)$}; \foreach \angulo in {0,2,...,358}{ \draw[cyan,very thick,opacity=0.12,rotate around z=\angulo] plot[domain=0:2,smooth,variable=\t] ({0},{\t},{9 + \t}); \draw[cyan,very thick,opacity=0.12,rotate around z=\angulo] plot[domain=0:2,smooth,variable=\t] ({0},{\t},{9 - \t}); } \foreach \z in {7.6,7.8,...,10.4}{ \pgfmathsetmacro{\r}{abs(\z-9)} \draw[cyan,thick,opacity=0.35] plot[domain=\tini:\tfin,smooth,variable=\t] ({\r*cos(\t r)},{\r*sin(\t r)},{\z}); } \foreach \z in {7.6,7.8,...,10.4}{ \pgfmathsetmacro{\r}{abs(\z-9)} \draw[cyan,thick,opacity=0.35] plot[domain=\tfin:\tend,smooth,variable=\t] ({\r*cos(\t r)},{\r*sin(\t r)},{\z}); } \pgfmathsetmacro{\r}{abs(\h-9)} \draw[red,very thick] plot[domain=0:360,smooth,variable=\t] ({\r*cos(\t)},{\r*sin(\t)},{\h}); \node[red, above right] at ({\r},0,\h) {$z=h$}; \fill[yellow,opacity=0.35] plot[domain=0:360,smooth,variable=\t] ({\r*cos(\t)},{\r*sin(\t)},0); \draw[red,thick] plot[domain=0:360,smooth,variable=\t] ({\r*cos(\t)},{\r*sin(\t)},0); \foreach \angle in {0,45,...,315}{ \pgfmathsetmacro{\x}{\r*cos(\angle)} \pgfmathsetmacro{\y}{\r*sin(\angle)} \draw[gray,dashed,opacity=0.5] (\x,\y,0) -- (\x,\y,\h); } \node[blue,right] at (0,0,11.5) {$x^2 + y^2 = (z-9)^2$}; \end{tikzpicture} \end{document}

I have created a custom ⍟ symbol using TikZ, which works well, except that it ignores the colour of the surrounding text. MWE: \documentclass{article} \usepackage{tikz} \usepackage{scalerel} \newsavebox{\whitecircstar}\sbox{\whitecircstar}{\kern.075em\tikz{\node[draw, circle,line width=.36pt, inner sep=0]{$*$};}\kern.075em} \newcommand{\ostar}{\mathbin{\scalerel*{\usebox{\whitecircstar}}{\odot}}} \begin{document} \textcolor{red}{Before $\ostar$ After} \end{document} Output: How can I make \ostar the same colour as the surrounding text? My understanding was that . was a special symbol for the current colour in xcolor, but adding color=. to the node arguments had no effect.

My goal is to get a rectangle like the one below, but with text in the nested rectangles. Line types could be for example the following: I saw tikz: Multiple splits of rectangle, but it does not answer the question on the line types. Beyond that, I am a beginner using Tikz, and I'd like the answer explained, since the linked answer is complex to understand. Thanks!

I would like to add a very large picture on a title page, covering the whole page with a large offset (picture pasted to the upper-left side of the page), blended on the page background (below the title, author's name and other text elements), with some transparency effect, and background blending effect. How should we achieve this? The picture is supposed to be partly shown on the page, about half of it showing on the upper-left side, like an "intrusion" on the page (sorry for the bad english description. I hope you get the picture). Here's a MWE to be modified, showing a title page prototype: \documentclass[11pt,twoside]{book} \usepackage[T1]{fontenc} \usepackage[tt=false]{libertinus} \usepackage[french]{babel} \usepackage[stretch=50]{microtype} \usepackage[letterpaper,left=1.25in,right=1in,top=0.5in,bottom=0.5in,includeheadfoot,headheight=15pt]{geometry} \usepackage{titlesec} \usepackage{graphicx} \usepackage[dvipsnames]{xcolor} \usepackage{float} \usepackage{fancyhdr} \usepackage[titles]{tocloft} \usepackage{shadowtext} \usepackage{tikz} \usetikzlibrary{calc} \begin{document} \frontmatter % Title Page : \begin{titlepage} \definecolor{lightbrown}{RGB}{177, 149, 93} \definecolor{darkbrown1}{RGB}{58, 41, 26} \definecolor{darkbrown2}{RGB}{50, 30, 0} % Frame : \begin{tikzpicture}[remember picture, overlay] \draw[line width = 1in,color = white] ($(current page.north west) + (0.25in,0.25in)$) rectangle ($(current page.south east) + (0.25in,-0.25in)$); \draw[line width = 0.25pt,color = black] ($(current page.north west) + (0.75in,-0.25in)$) rectangle ($(current page.south east) + (-0.25in,0.25in)$); %\draw[line width = 1pt,color = darkbrown1] ($(current page.north west) + (1in,-0.5in)$) rectangle ($(current page.south east) + (-0.5in,0.5in)$); \end{tikzpicture} \shadowoffsetx{2.5pt} \shadowoffsety{3.5pt} \shadowcolor{gray!80} \definecolor{pagetitre}{RGB}{150,120,100} \pagecolor{pagetitre} \centering \vspace*{\baselineskip} \vfill {\textcolor{black}{\fontsize{26}{0}\selectfont\sffamily\textbf{\shadowtext{Some Nice Title Here}}}} \\[2.5\baselineskip] {\textcolor{black}{\huge\sffamily\scshape Someone}} \vfill \vfill \includegraphics[width=11cm]{example-grid-100x100pt} \vfill {\textcolor{black}{\Large\selectfont\sffamily\scshape Some copyright notice}} \end{titlepage} \pagecolor{white} Blabla \end{document} So how can I add a very large picture blended with the page background colour, with some transparency effect, and a large up-left offset? The large picture should fit inside the frame defined with the tikzpicture environment, and stay below all text on the title page.

I want to create 3D dice in LaTeX. I am familiar with the excellent package "customdice", but it unfortunately only produces 2D images. I am also inspired by the answer from hpekristiansen to this question. It creates beautiful dice, but I am uanble to change from colored circles to the familiar circle symbols for the numbers 1 to 6. One idea I had was to try to put the images from customdice on each of the surfaces, but I am unable to make it work. I believe the package customdice doesn't agree well to the packages required in the question linked above. Could anyone help me create "normal" dice faces on the surfaces on the answer linked above?

I am trying to do something very similar to what witharrows package does. However, while the witharrows package connects two lines of equations with an arrow to the right side of the equations, as the figure below shows, I wish to put vertical arrows in between the equal signs like the figure shown below. Is there anyway to do this? either by making a change to witharrows or defining a new command? I am pretty new to Latex so I need some guidance. Thanks in advance!

Can someone help me write the tikz code to generate the following images? I've tried adapting what some other people have done to generate a cylinder, but I want the cylinder with the axes and with the smaller cylinder inside. The code written here is perhaps most useful, Concentric Cylinders with tikz The code for a basic cylinder is given here 3D bodies in TikZ I'm new to tikz and have found that upon editing, the lines and dimensions go out of proportion and don't look reasonable any more. I also don't understand how to include lines in these cylinders or how to shade the inside cylinder.

I'm trying to customize my TOC as in this post (second example) and I'm having two issues. The first one is documented but I can't figure out what I'm doing wrong : I want to write "Appendix" instead of "Chapter". If I don't customize \titlecontents{chapter} then everything works fine, but if I do, I get a "Chapter" instead of "Appendix". I've tried all sorts of configs (I think it's due to the book class), with/without \begin{appendices}, loading (or not) the appendix package with the titletoc options... Any help would be very appreciated ! The second "problem" I'm having is I'm trying to customize the look of the subsections in the TOC according to the chapter they're in. Each chapter has its own color and I would like the sections to have the same color as the chapter they're in. Here is my MWE and the result. \documentclass[11pt]{book} \usepackage[table]{xcolor} \usepackage{ifthen} \usepackage{tikz,pgf} \definecolor{chapa}{HTML}{15CA7F} \definecolor{chapb}{HTML}{CA16BD} \definecolor{chapc}{HTML}{DE1841} \makeatletter \newcommand{\ch@p}{chapa} \newcommand{\ch@ngeCouleurs}[1] { \ifthenelse{\equal{#1}{1}}{\renewcommand{\ch@p}{chapa}}{} \ifthenelse{\equal{#1}{2}}{\renewcommand{\ch@p}{chapb}}{} \ifthenelse{\equal{#1}{3}}{\renewcommand{\ch@p}{chapc}}{} } \usepackage[titletoc]{appendix} \usepackage{titletoc} \usepackage{titlesec} \contentsmargin{-1.5cm} \titlecontents{chapter}[4pc] {\addvspace{30pt}% \ch@ngeCouleurs{\thecontentslabel}% \begin{tikzpicture}[remember picture, overlay]% \draw[\ch@p,fill=\ch@p] (-4.2,-.1) rectangle (-.8,.5);% \pgftext[left,x=-3.7cm,y=0.2cm]{\color{white}\large\bfseries\sc\@chapapp\ \thecontentslabel};% \end{tikzpicture}% \large\bfseries\color{\ch@p!80!black}}% {} {} {\titlerule\, Page \thecontentspage \begin{tikzpicture}[remember picture, overlay] \draw[\ch@p] (2pt,0) rectangle (6,0.1pt); \end{tikzpicture}% } [\addvspace{.2cm}]% \titlecontents{section}[0pc] {\addvspace{5pt}} { \color{\ch@p}\contentslabel[\thecontentslabel]{2pc}\color{black}} {} {\hfill\small\color{black}\thecontentspage} [\addvspace{3pt}] \makeatother \begin{document} \tableofcontents \chapter{One chapter} \section{First section} \section{First subsection} \chapter{Another chapter} \section{Foo} \section{Bar} \begin{appendices} \chapter{First appendix} \end{appendices} \end{document} The result (2.1 and 2.2 should be in purple, and "Chapter A" should be "Appendix A"). I think I know how to work around the coloring problem of the appendix (comes from the fact that the chapter counter has been reset which can be avoided using packages totcount and assoccnt). But I don't understand why my \ch@ngeCouleurs macro has no effect on the \titlecontents{section}. If I could access the chapter number in the \titlecontents{section}, that would solve my problem. Thank you for reading my (long) post ! And thanks to anyone who can provide help !
