TikZ

I plotted a sinusoidal function using the axis environment from the pgfplots package. My code \documentclass[margin=3mm]{standalone} \usepackage{pgfplots} \pgfplotsset{compat=1.18} \begin{document} \begin{tikzpicture} \begin{axis}[ width=50cm, height=0.80\textwidth, axis y line=middle, axis x line=middle, axis on top, % <-- Correct pgfplots key to draw ticks, grid, and lines over plots xmin=-15, xmax=5.8, ymin=-125, ymax=125, xtick={-14,-3*pi,-5*pi/2,-2*pi,-3*pi/2,-pi,-pi/2,0,1,pi/2,pi,3*pi/2,2*pi}, xticklabels={$-\inf$,$-3\cdot\pi$,$-\frac{5}{2}\cdot\pi$,$-2\cdot\pi$,$-\frac{3}{2}\cdot\pi$,$-\pi$,$-\frac{1}{2}\cdot\pi$,$0$,1,$\frac{1}{2}\cdot\pi$,$\pi$,$\frac{3}{2}\cdot\pi$,$2\cdot\pi$}, ytick={-112.5,-112.5/sqrt(2),0,112.5/sqrt(2),112.5}, yticklabels={-112.5,,0,,112.5}, legend cell align={left}, grid=both, grid style={line width=.1pt, draw=gray!10}, major grid style={line width=.2pt, draw=gray!20}, xlabel={$\alpha=\omega\cdot t$ in rad}, ylabel={$p(t)$ in Watt}, xlabel style={at={(ticklabel* cs:1)}, anchor=north west}, ylabel style={at={(ticklabel* cs:1)}, anchor=south west} ] % 1.

I'm totally open to creative ideas or completely different approaches. Any suggestions are very welcome! 🙂

I am writing a document and used tikzpicture in an example. After the example, a section begins. But after compiling, I am getting the next section before the tikzpicture diagram, while my code says it to do otherwise. Why is it happening? I am sharing a fragment of the code here as the code for the whole document is too long: \documentclass[a4paper,12pt]{article} \usepackage{amsmath,amssymb,graphicx,tikz,amsthm} \usetikzlibrary{positioning} \setlength{\topmargin}{-0.5in} \setlength{\topskip}{0.275in} % between header and text \setlength{\textheight}{9.5in} % height of main text \setlength{\textwidth}{6.25in} % width of text \setlength{\oddsidemargin}{0.1in} % odd page left margin \setlength{\evensidemargin}{0.1in} \newtheorem{theorem}{Theorem}[section] \theoremstyle{definition} \newtheorem{definition}{Definition}[section] \newtheorem{example}{Example} \begin{document} \begin{example} Here we give examples of two simple graphs where adding an edge results in spectral integral variation in one and two places.

I'm not very skilled using TikZ but I wanted to use it for all the figures in my bachelors thesis. So far I created this TikZ-picture: \documentclass{article} \usepackage{tikz} \usetikzlibrary{patterns} \usetikzlibrary{patterns.meta} \usetikzlibrary{decorations.pathreplacing} \usetikzlibrary{decorations.pathmorphing} \usetikzlibrary{decorations.markings} \usetikzlibrary{snakes} \usetikzlibrary{arrows.meta} \usetikzlibrary{calc,patterns,angles,quotes} \usepackage[table]{xcolor} \definecolor{Minzgrün}{RGB}{0,140,79} \definecolor{Fenstergrau}{RGB}{128,128,128} \definecolor{Telegrau 4}{RGB}{230,230,230} \definecolor{Tomatenrot}{RGB}{140,28,0} \begin{document} \begin{tikzpicture} [x=0.35cm,y=0.2cm,line cap=round,line join=round] \draw[line width=1.5pt] (17.5,12.5) arc [start angle=0, end angle=180, x radius=2.5, y radius=1]; \draw [black, line width=1pt] (16,13) -- (21,14) node [align=center,right]{Detector\\window}; \draw[line width=1.5pt] (19,2) arc [start angle=0, end angle=180, x radius=4, y radius=1.5]; \draw[black,line width=1.5pt] (5,0.5) -- (25,0.5) -- (25,2) -- (5,2) -- cycle; \draw[black,line width=1.5pt] (10,25) -- (10,12.5) -- (20,12.5) -- (20,25); \draw[black,line width=1.5pt] (12.5,17.5) -- (17.5,17.5) -- (17.5,20) -- (12.5,20) -- cycle; \fill[black,pattern=crosshatch dots] (12.5,17.5) -- (17.5,17.5) -- (17.5,20) -- (12.5,20) -- cycle; \draw [black,line width=1pt] (12,20) -- (8.5,21) node[align=center,left] {Energy-dispersive\\detector}; \draw[Fenstergrau,line width=1pt,postaction={decorate,decoration={markings,mark=at position 0.15 with{\arrow{>}},mark=at position 1 with {\arrow{>}}}}] (-5,4) -- (10,2) -- (25,4); \draw[Fenstergrau,line width=1pt,postaction={decorate,decoration={markings,mark=at position 0.15 with{\arrow{>}},mark=at position 1 with {\arrow{>}}}}] (5,4) -- (20,2) -- (35,4); \node[align=center] at (0,6.5){Incident beam}; \node[align=center] at (30,6.5){Reflected beam}; \draw[black,line width=1pt] (12.5,1.25) -- (10,-2.5) node [below, align=center] {Sample carrier\\(\textit{reflector})}; \draw[black,line width=1pt] (16,2.5) -- (21,-2.5) node [below, align=center] {Sample}; \draw[Minzgrün,line width=1.25pt,->,decorate,decoration={snake,amplitude=0.1cm,segment length=0.4cm, post length=0.2cm}](15,2.5) -- (15,17); \draw [black, line width=1pt] (14,8) -- (9,12) node [align=center, left] {Fluorescence\\radiation}; \end{tikzpicture} \end{document} But I would like to include the X-ray beams as wave fronts which interfere above the sample to form a standing wave like in this image: Sadly this is beyond my TikZ-skills.

I would like to create a water level, i.e. a transparent flexible tube filled with water, so that the principle of communicating vessels is clearly illustrated. How can I represent the flexible tube, keeping it along the horizontal surface and making it run up the two vertical sides, so that the configuration is similar to the one shown in the image? Here my 1st MWE: \documentclass{article} \usepackage{tikz} \usepackage{tikzphysics} \begin{document} \begin{tikzpicture}[ line cap=round, line join=round ] \node[ ground, ground width=8.6cm, ground depth=3mm ] (G) at (0,0) {}; \node[ ground, ground width=3.2cm, ground depth=3mm, rotate=90 ] (GL) at (-3.5,1.6) {}; \node[ ground, ground width=3.2cm, ground depth=3mm, rotate=90 ] (GR) at (3.5,1.6) {}; \draw[dashed, thick] (-3.9,2.8) -- (4.2,2.8); \draw[thin] (-3.9,0) -- (-3.7,0); \node[left] at (-3.7,3.1) {\small 100.0}; \draw[thin] (-3.2,0) -- (-3.2,3.1); \draw[thin] (3.8,0) -- (3.8,3.1); \draw[thin] (3.7,0) -- (3.9,0); \node[right] at (3.9,3.1) {\small 100.0}; \draw[thin] (-4.3,0) -- (-3.8,0); \node[left] at (-4.3,0.08) {\small 0.00}; \end{tikzpicture} \end{document} Now with Mathcha I have created the flexible tube, \documentclass{article} \usepackage[margin=0.5in]{geometry} \usepackage{tikz} \usepackage{tikzphysics} \definecolor{water}{RGB}{73,194,221} \pagestyle{empty} \begin{document} \centering \begin{tikzpicture}[x=1cm,y=1cm] \node[ ground, ground width=8.6cm, ground depth=3mm ] (G) at (0,0) {}; \node[ ground, ground width=3.2cm, ground depth=3mm, rotate=90 ] (GL) at (-3.5,1.6) {}; \node[ ground, ground width=3.2cm, ground depth=3mm, rotate=90 ] (GR) at (3.5,1.6) {}; \draw[dashed, thick] (-3.9,2.5) -- (4.2,2.5); \draw[thin] (-3.9,0) -- (-3.7,0); \node[left] at (-3.7,3.1) {\small 100.0}; \draw[thin] (-3.2,0) -- (-3.2,3.1); \draw[thin] (3.8,0) -- (3.8,3.1); \draw[thin] (3.7,0) -- (3.9,0); \node[right] at (3.9,3.1) {\small 100.0}; \draw[thin] (-4.3,0) -- (-3.8,0); \node[left] at (-4.3,0.08) {\small 0.00}; \begin{scope}[shift={(-6cm,-.9cm)}] \draw[gray!70,line width=7pt] (3.48,4.32) .. controls (3.48,3.98) and (3.71,3.58) ..

I want to get rather than Appending (0,0) circle (3.5) is fine but I am wondering whether there are any nicer approaches. odd even rule does not exist too. \documentclass[tikz,border=1cm,12pt]{standalone} \begin{document} \begin{tikzpicture}[ultra thick] \filldraw[fill=red,even odd rule] \foreach \i in {0,0.5,...,3.5}{(0,0) circle (\i)} (0,0) circle (3.5) % just a hack to invert the even odd rule ; \end{tikzpicture} \end{document}

Is it possible to set shape border rotate to a new default for a particular shape? For example, say I want to define a shape (which I'll call trapezoid in the MWE) that is essentially a trapezium but it is rotated by 180° by default. For example, \documentclass{standalone} \usepackage{tikz} \usetikzlibrary{shapes.geometric} \pgfdeclareshape{trapezoid}{% \nodeparts{text}% \inheritsavedanchors[from=trapezium]% \inheritbackgroundpath[from=trapezium]% \inheritanchorborder[from=trapezium]% \inheritanchor[from=trapezium]{text}% \inheritanchor[from=trapezium]{center}% \inheritanchor[from=trapezium]{north}% \inheritanchor[from=trapezium]{south}% \inheritanchor[from=trapezium]{east}% \inheritanchor[from=trapezium]{west}% \inheritanchor[from=trapezium]{north west}% \inheritanchor[from=trapezium]{north east}% \inheritanchor[from=trapezium]{south west}% \inheritanchor[from=trapezium]{south east}% \behindbackgroundpath{% \pgfpathmoveto{\lowerleftpoint}% \pgfpathlineto{\upperrightpoint}% }% }% \begin{document} \begin{tikzpicture} \node [draw,trapezium,minimum size=1cm] {}; \node [draw=blue,trapezoid,minimum size=1cm,name=s] at (0,-1.25) {}; \node [draw=orange,trapezoid,minimum size=1cm,shape border rotate=180] at (0,-2.5) {}; % \foreach \anchor/\placement/\color in {north/above/orange,south/below/teal, % east/right/red,west/left/green,50/above/violet} % \draw [color=\color,shift=(s.\anchor)] plot [mark=x] coordinates {(0,0)}; \end{tikzpicture} \end{document} but both the blue and the orange shapes should be the same. Alternatively, the blue one could be narrow-end-on-top, and the orange one rotates 180° more and looks like the black one. Options I have considered: Define a new shape and a new set of keys to go with it that are very similar to trapezium except upside-down (this is the worst option) Define trapezoid as a style that calls another shape (say, decorated trapezium or some such) whose only real purpose is to set another default value of shape border rotate Create an anchor that reads another key (say, trapezoid rotate) that determines what the user wants the new angle to be, then sets shape border rotate to something based on that. I am hoping there is another way, something like issuing \changepgfinitialvalue inside the shape definition so that the initial value changes for that shape (and only that shape). Is there? Clarification: what I want is a shape (I used trapezium here, but it could be something else) that looks similar to an existing one, but has extra things drawn on it, an appendage of some sort, etc., but the base shape is rotated with respect to the original. If there is a way to do this so that the user who calls, say, shape=trapezoid instead of just trapezoid without reverting the orientation, that would be my preference. In other words, inherit everything from a shape, build on it with \beforebackgroundpath, \foregroundpath, and such, and change the default orientation.

I want to change the style of objects in tikz to some kind of "stamp"-style, where the objects are kind of not perfectly drawn and contain "imperfections" or faded elements. For me it is hard to explain what I mean by that, so I have included a picture that shows what I mean: I want to be able to apply this kind of effect (as "irregular" and "asymmetric" as possible) to different objects in tikz, in particular to texts (even if using a different font with xetex), lines, rectangles, ellipses and if possible even pictures. This should work with different colors. The following MWE includes the objects that I wish to apply this effect to (but I have no idea how to even start): \documentclass{standalone} \usepackage{tikz} \usetikzlibrary{decorations.text} \usepackage[T1]{fontenc} \usepackage{xltxtra} \setmainfont{Algerian} \begin{document} \begin{tikzpicture} \draw (0,0) ellipse (4cm and 2cm); \draw[line width=1.5mm, yellow] (0,0) ellipse (3.8cm and 1.8cm); \node at (0,0) {\includegraphics[height=2.2cm]{example-image}}; \draw[white,thick,postaction={decorate,decoration={text along path,text align=center,text={This Is A Text}}}] (-2,1.0) to [bend left=15] (2,1.0); \draw[white,thick,postaction={decorate,decoration={text along path,text align=center,text={This Is Another Text}}}] (-2,-1.42) to [bend left=-15] (2,-1.42); \draw[red, fill=yellow] (2,-0.5) rectangle (3,0.5); \draw[green, fill=green](-3,-0.5) rectangle (-2,0.5); \end{tikzpicture} \end{document}

I am just a beginner and am writing my first report in LaTeX, so excuse me if the solution is very obvious. I am trying to plot asymptotic approximation of bode plots using the package bodeplot as answered here, I simply copied and pasted the following sample code as give in the documentation, \begin{BodeMagPlot}[% axes/{height=2cm, width=4cm} ] {0.01} {100} \addBodeZPKPlots[% asymptotic/{blue,dotted,thick}% ] {magnitude} {% z/{0,{-0.1,-0.5},{-0.1,0.5}}, p/{{-0.5,-10},{-0.5,10}}, k/10% } \end{BodeMagPlot} Now if I am using Overleaf to compile, I am getting the expected results, but then when I use the exact syntax in MikTeX installed on my PC, I do not get any plot, and instead, two warnings messages are displayed: \ifplatform.sty:0:shell escape is disabled, so I can only detect \ifwindows You have an axis with empty range (in direction y). Replacing it with a default range and clearing all plots As far as I can tell the second warning is why I didn't get any plot, but I couldn't understand how to rectify this by giving the range for y-axis, and why does this run in Overleaf, but not on my system? And if the first warning is responsible for this somehow.

Disclaimer: I am new-ish to LaTeX, and self-taught. I am trying to make a "Unit Circle" TikZ graphic, in which I would like to have the \degree symbol from the gensymb package in the label text of a node. My current workflow involves the standalone package, and uses the \include command to create a sort of "master file" containing each of my creations on its own page which I reference in other Overleaf projects using the 'output file from another project' and the graphicx package to reduce compile time. There is probably a better way to do this, but it keeps it simple enough for me and I like having everything in more or less the same place so I can make quick references between my images. It has worked so far, until now... My problem is, it is preferable if I don't have to update the preamble of my master document every time I add a new picture, especially since that's where I define things like colors which occasionally use identical names (e.g. gradient1). Hence, I load \usepackage[subpreambles]{standalone} to read the preamble of each standalone separately. Again, this has worked well enough so far that I have been able to solve any hiccups myself. I have failed to diagnose why exactly, but there is something going on with the [subpreambles] tag and loading the gensymb package. Here is my MWE: \documentclass[tikz]{standalone} \usepackage{textcomp,gensymb} % for degree symbol \begin{document} \begin{tikzpicture} \node at (0,0) {$0\degree$}; \end{tikzpicture} \end{document} which I have in Overleaf as degree-test.tex. When I try to reference this file in another: \documentclass[tikz]{standalone} \usepackage[subpreambles]{standalone} \begin{document} \include{degree-test} \end{document} I get the error: Package standalone Warning: Sub-preamble of file 'degree-test.tex' has changed. Content will be ignored. Please rerun LaTeX! on input line 4. I compile with LuaLaTeX, but other compilers produce similar results. Even removing \degree from the node label produces the error, despite not actually using the symbol. There must be some kind of conflict with commands which define certain things during the preamble, but I don't know how to read the error logs and they're very frightening on the surface. Is there a simple fix for this? EDIT: I have also disqualified \documentclass[tikz]{standalone} and \include vs \includestandalone as culprits.

I'm trying to plot the most simple Bode plot of the most simple lowpass filter function, given as G(s) = 1/(s+1).

I am trying to draw the following six hemispheres next to each other with their centers aligned on a horizontal line. I am using Alenanno's answer to the question. I have done this just for the hemisphere with z > 0 using the following code taken from the question. \documentclass[12pt]{report} \usepackage{tikz} \usepackage{tikz-3dplot} \begin{document} \tdplotsetmaincoords{60}{110} \pgfmathsetmacro{\radius}{1} \pgfmathsetmacro{\thetavec}{0} \pgfmathsetmacro{\phivec}{0} \begin{tikzpicture}[scale=1,tdplot_main_coords] \tdplotsetthetaplanecoords{\phivec} \draw[dashed] (\radius,0,0) arc (0:360:\radius); \shade[ball color=blue!10!white,opacity=0.2] (1cm,0) arc (0:-180:1cm and 5mm) arc(180:0:1cm and 1cm); \shade[ball color=blue!10!white,opacity=0.2] (1cm,0) arc (180::1cm and 5mm) arc(360:0:1cm and 1cm); \end{tikzpicture} \end{document}

I am having trouble adding a TikZ graphic to my Beamer presentation which uses the theme Metropolis. Here is an example of the issue: \documentclass{beamer} \usepackage[utf8]{inputenc} \usepackage{pgfplots} %\usetheme{metropolis} \pgfplotsset{compat=1.18} \begin{document} \begin{frame} \begin{center} \begin{tikzpicture} \begin{axis}[ view = {135}{20}, xlabel=$x$, ylabel=$y$, zlabel=$z$, xmin=-1, xmax=1, ymin=-1, ymax=1, zmin=0, zmax=1, ] \draw (0, 1, 0) -- (1, 1, 1); \end{axis} \end{tikzpicture} \end{center} \end{frame} \end{document} This code does what I want, but uncommenting the line \usetheme{metropolis} changes the graphic and makes the line shorter. (I don't think it's invisible, just a very small length.) How can I get the desired image while still using the Metropolis theme?

I was reading about drawing differential equation trajectories with latex, but I wonder... is there a way to graph this? Consider the system x'=-y+xz^2 y'=x+yz^2 z'=-z(x^2+y^2) The following image I have taken from Perko's book Differential Equations and Dynamical Systems

I am trying to plot this parametric function: (cos(t)+(t)*sin(t), sin(t)+(t)*cos(t)) (0≤t≤π) which gives the curve below: This is my attempt, but for some reason it doesn't work. \documentclass{article} \usepackage{tikz} \begin{document} \begin{tikzpicture} \draw[thick] plot[variable=\t,domain=0:180,smooth,thick] ({cos(\t)-(\t)*sin(\t)},{sin(\t)-(\t)*cos(\t)}); \end{tikzpicture} \end{document} How should I fix these codes?

I would like to incrementally or animatedly reveal the elements of a matrix. Ideally I would like to just fade in the elements (à la beamer's overlay) from gray to black on each advance but I would settle for a change of background to the cell (from a light gray to white). What I have is unsatisfactory: \begin{tikzpicture} % \tikzstyle{unseen} = [color=blue!70] \tikzstyle{seen} = [] \matrix (m) [matrix of math nodes, nodes in empty cells, minimum size=7mm, ampersand replacement=\&, every node/.style={font={\large\ttfamily\bfseries},fill=gray!10}] { 1 \& 0 \& 0 \& 0 \& 0 \& 0 \& 0 \\ 0 \& 1 \& 1 \& 1 \& 0 \& 0 \& 0 \\ 0 \& 1 \& 1 \& 0 \& 1 \& 1 \& 0 \\ 0 \& 0 \& 0 \& 1 \& 1 \& 1 \& 0 \\ 0 \& 0 \& 0 \& 0 \& 0 \& 0 \& 1 \\ }; \foreach \f/\r/\c in {1/2/1,2/3/1} { \draw<\f->[seen] (m-\r-\c.north west) rectangle (m-\r-\c.south east); } \end{tikzpicture} Since these are (for now) sparse binary matrices could I make the foreach list insert the 1 entries?

I'm trying to draw a set of rotated rectangular cuboids around a centre point in Tikz. I've created an example of what I'm trying to achieve in OpenSCAD below with the code to generate the above figure in OpenSCAD: for (i = [0:45:360]) { rotate([0,i,0]) { translate([2,0,-0.5]){ cube([2,0.5,1]); } } } The purpose is to draw the ferrites in an Inductive Power Transfer Magnetic Coupler (pad), an example of the diagram I would like to draw is below I think, the other parts are quite achievable, but the rotated blocks are a challenge. I guess because, as many people have noted, TikZ does not have a 3D engine. I have had a go at making something like what I want here: \documentclass[border=7pt]{standalone} \usepackage{tikz} \usepackage{tikz-3dplot} %%%%%%%%%%% \begin{document} \tdplotsetmaincoords{-60}{-50} \begin{tikzpicture} [ tdplot_main_coords, ] \def\rounding{0.2pt}; \foreach \i in {10,50,...,360} { \begin{scope}[rotate around={\i:(0.4,0,0.0)}] \pgfmathsetmacro{\cubex}{1} \pgfmathsetmacro{\cubey}{0.1} \pgfmathsetmacro{\cubez}{0.1} % http://tex.stackexchange.com/questions/12020/what-is-the-easiest-way-to-draw-3d-cube-with-tikz \draw[rounded corners = \rounding,fill=black!70] (0,0,0) -- ++(-\cubex,0,0) -- ++(0,-\cubey,0) -- ++(\cubex,0,0) -- cycle; \draw[rounded corners = \rounding,fill=black!70] (0,0,0) -- ++(0,0,-\cubez) -- ++(0,-\cubey,0) -- ++(0,0,\cubez) -- cycle; \draw[rounded corners = \rounding,fill=black!70] (0,0,0) -- ++(-\cubex,0,0) -- ++(0,0,-\cubez) -- ++(\cubex,0,0) -- cycle; \end{scope} } \end{tikzpicture} \end{document} which currently looks like this I had to set the \tdplotsetmaincoords{-60}{-50} to a negative number, otherwise you see the 'back' of the cuboid. I don't know, how to make the circle of cuboids lean back into the page, any help would be greatly appreciated. I also don't know, how to rotate the cubes so they look right, at the moment it looks quite odd.

I would like to draw border strip tableaux in Latex. Such a tableau is a tiling of a partition shape (or skew-partition shaped) diagram with labeled border strips such that in each row and column, the labels are increasing. For a precise definition, see page 351 in http://www-math.mit.edu/~rstan/pubs/pubfiles/123.pdf In the picture, all the border strips are of the same length. This special case is enough for my purposes but does not hold in general. The picture is copied from Figure 2.4 in http://www.ams.org/journals/tran/2000-352-12/S0002-9947-00-02666-0/S0002-9947-00-02666-0.pdf

My questions are: Is there a possibility to get a view of a Rubik's Cube in TikZ such as in pgfplots; like view={NUMBER1}{NUMBER2}? How can be the Rubik's Cube be scrambled with a number a, such that this number makes a random pattern to the cube (→ scrambeling). Here is my MWE (it's just the Cube without any functions): \documentclass[border=5pt,tikz]{standalone} \usetikzlibrary{3d} \begin{document} \begin{tikzpicture}[every node/.style={inner sep=1cm,draw,very thick},very thick] \draw[step=2cm,canvas is yz plane at x=0] (0,0) grid (8,8); \node[fill=red] at (-4.08,-2.09) {}; \node[fill=white] at (-4.08,-.09) {}; \node[fill=blue] at (-4.08,1.91) {}; \node[fill=red] at (-4.08,3.91) {}; \begin{scope}[shift={(-2,0)}] \node[fill=blue] at (-4.08,-2.09) {}; \node[fill=white] at (-4.08,-.09) {}; \node[fill=orange] at (-4.08,1.91) {}; \node[fill=white] at (-4.08,3.91) {}; \end{scope} \begin{scope}[shift={(-4,0)}] \node[fill=yellow] at (-4.08,-2.09) {}; \node[fill=blue] at (-4.08,-.09) {}; \node[fill=white] at (-4.08,1.91) {}; \node[fill=green] at (-4.08,3.91) {}; \begin{scope}[shift={(-2,0)}] \node[fill=white] at (-4.08,-2.09) {}; \node[fill=red] at (-4.08,-.09) {}; \node[fill=blue] at (-4.08,1.91) {}; \node[fill=yellow] at (-4.08,3.91) {}; \end{scope} \end{scope} \draw[xshift=-8cm,yshift=8cm,step=2cm,canvas is xz plane at y=0] (0,0) grid (8,8); \draw[fill=yellow,canvas is yz plane at x=0] (0,0) rectangle (2,2); \draw[yshift=2cm,fill=blue,canvas is yz plane at x=0] (0,0) rectangle (2,2); \draw[yshift=6cm,fill=orange,canvas is yz plane at x=0] (0,0) rectangle (2,2); \begin{scope}[shift={(-.77,-.77)}] \draw[fill=green,canvas is yz plane at x=0] (0,0) rectangle (2,2); \draw[yshift=2cm,fill=orange,canvas is yz plane at x=0] (0,0) rectangle (2,2); \draw[yshift=4cm,fill=orange,canvas is yz plane at x=0] (0,0) rectangle (2,2); \draw[yshift=6cm,fill=blue,canvas is yz plane at x=0] (0,0) rectangle (2,2); \end{scope} \begin{scope}[shift={(2*-.77,2*-.77)}] \draw[fill=red,canvas is yz plane at x=0] (0,0) rectangle (2,2); \draw[yshift=2cm,fill=yellow,canvas is yz plane at x=0] (0,0) rectangle (2,2); \draw[yshift=4cm,fill=red,canvas is yz plane at x=0] (0,0) rectangle (2,2); \draw[yshift=6cm,fill=red,canvas is yz plane at x=0] (0,0) rectangle (2,2); \end{scope} \begin{scope}[shift={(3*-.77,3*-.77)}] \draw[fill=blue,canvas is yz plane at x=0] (0,0) rectangle (2,2); \draw[yshift=2cm,fill=orange,canvas is yz plane at x=0] (0,0) rectangle (2,2); \draw[yshift=4cm,fill=yellow,canvas is yz plane at x=0] (0,0) rectangle (2,2); \draw[yshift=6cm,fill=blue,canvas is yz plane at x=0] (0,0) rectangle (2,2); \end{scope} \draw[yshift=8cm,xshift=-2cm,fill=blue,canvas is xz plane at y=0] (0,0) rectangle (2,2); \draw[yshift=7.23cm,xshift=-2.76cm,fill=orange,canvas is xz plane at y=0] (0,0) rectangle (2,2); \draw[yshift=6.46cm,xshift=-3.55cm,fill=green,canvas is xz plane at y=0] (0,0) rectangle (2,2); \begin{scope}[shift={(-2,0)}] \draw[yshift=8cm,xshift=-2cm,fill=green,canvas is xz plane at y=0] (0,0) rectangle (2,2); \draw[yshift=7.23cm,xshift=-2.76cm,fill=white,canvas is xz plane at y=0] (0,0) rectangle (2,2); \draw[yshift=6.46cm,xshift=-3.55cm,fill=red,canvas is xz plane at y=0] (0,0) rectangle (2,2); \draw[yshift=5.68cm,xshift=-4.33cm,fill=red,canvas is xz plane at y=0] (0,0) rectangle (2,2); \end{scope} \begin{scope}[shift={(-4,0)}] \draw[yshift=8cm,xshift=-2cm,fill=yellow,canvas is xz plane at y=0] (0,0) rectangle (2,2); \draw[yshift=7.23cm,xshift=-2.76cm,fill=yellow,canvas is xz plane at y=0] (0,0) rectangle (2,2); \draw[yshift=6.46cm,xshift=-3.55cm,fill=green,canvas is xz plane at y=0] (0,0) rectangle (2,2); \draw[yshift=5.68cm,xshift=-4.33cm,fill=red,canvas is xz plane at y=0] (0,0) rectangle (2,2); \end{scope} \begin{scope}[shift={(-6,0)}] \draw[yshift=8cm,xshift=-2cm,fill=green,canvas is xz plane at y=0] (0,0) rectangle (2,2); \draw[yshift=7.23cm,xshift=-2.76cm,fill=red,canvas is xz plane at y=0] (0,0) rectangle (2,2); \draw[yshift=6.46cm,xshift=-3.55cm,fill=yellow,canvas is xz plane at y=0] (0,0) rectangle (2,2); \draw[yshift=5.68cm,xshift=-4.33cm,fill=red,canvas is xz plane at y=0] (0,0) rectangle (2,2); \end{scope} \begin{scope}[yshift=-4cm] \fill[black,canvas is zy plane at x=0] (0,0) rectangle (1.5,1.5); \fill[xshift=-2.05cm,yshift=-.58cm] (0,0) rectangle (1.5,1.5); \fill[xshift=-1.5cm,yshift=1.49cm,canvas is zx plane at y=0] (0,0) rectangle (1.5,1.5); \fill[rounded corners=5,blue,canvas is zy plane at x=0] (0,0) rectangle (1.5,1.5); \fill[rounded corners=5,xshift=-2.05cm,yshift=-.58cm,red] (0,0) rectangle (1.5,1.5); \fill[rounded corners=5pt,xshift=-1.5cm,yshift=1.49cm,canvas is zx plane at y=0,white] (0,0) rectangle (1.5,1.5); \node[fill=white,inner sep=0pt,draw=white] (n) at (-1.3,-1.7) {Another style}; \draw[line width=1pt,->] (n) --+ (0,1); \end{scope} \end{tikzpicture} \end{document} Here is the original picture: And the output:

How can I get tikz node dimensions such as height and width? I am interested to use these parameters to precisely calculate placement of objects, e.g. using <a.height> in the following example: \documentclass{article} \thispagestyle{empty} \usepackage{graphicx} \usepackage{tikz} \begin{document} \begin{figure} \begin{tikzpicture} \node(a) { \includegraphics[width=0.8\textwidth]{example-image-a} }; \node(b) at (0, <a.height>*3/4){label}; \end{tikzpicture} \end{figure} \end{document}

In a paper, I have a class of functions S1→S2 depending on a real parameter t>0, and I would like to represent some of them on the sphere as curves to illustrate their behavior as t goes to 0, but I never used TikZ or anything else, so I have no clue how to do so.

Drawing a sphere is easy enough using the ball shading, or some more refined form as in How to draw a shaded sphere, but I would like a way to shade only one half (or even just slices). I currently have the following: \documentclass{standalone} \usepackage{tikz} %% helpers for 3D sphere drawing \newcommand\pgfmathsinandcos[3]{% \pgfmathsetmacro#1{sin(#3)}% \pgfmathsetmacro#2{cos(#3)}% } \newcommand\LongitudePlane[3][current plane]{% \pgfmathsinandcos\sinEl\cosEl{#2} % elevation \pgfmathsinandcos\sint\cost{#3} % azimuth \tikzset{#1/.style={cm={\cost,\sint*\sinEl,0,\cosEl,(0,0)}}} } \newcommand\LatitudePlane[3][current plane]{% \pgfmathsinandcos\sinEl\cosEl{#2} % elevation \pgfmathsinandcos\sint\cost{#3} % latitude \pgfmathsetmacro\yshift{\cosEl*\sint} \tikzset{#1/.style={cm={\cost,0,0,\cost*\sinEl,(0,\yshift)}}} % } \newcommand\DrawLongitudeCircle[2][2]{ \LongitudePlane{\angEl}{#2} \tikzset{current plane/.prefix style={scale=#1}} % angle of "visibility" \pgfmathsetmacro\angVis{atan(sin(#2)*cos(\angEl)/sin(\angEl))} % \draw[current plane, very thin] (\angVis:1) arc (\angVis:\angVis+180:1); \draw[current plane,dashed,very thin] (\angVis-180:1) arc (\angVis-180:\angVis:1); } \newcommand\DrawLatitudeCircle[2][3]{ \LatitudePlane{\angEl}{#2} \tikzset{current plane/.prefix style={scale=#1}} \pgfmathsetmacro\sinVis{sin(#2)/cos(#2)*sin(\angEl)/cos(\angEl)} % angle of "visibility" \pgfmathsetmacro\angVis{asin(min(1,max(\sinVis,-1)))} \draw[current plane] (\angVis:1) arc (\angVis:-\angVis-180:1); \draw[current plane,dashed] (180-\angVis:1) arc (180-\angVis:\angVis:1); } \begin{document} \begin{tikzpicture} \def\R{2.5} % sphere radius \def\angEl{35} % elevation angle \def\angAz{-105} % azimuth angle \tikzset{xyplane/.style={cm={cos(\angAz),sin(\angAz)*sin(\angEl),-sin(\angAz), cos(\angAz)*sin(\angEl),(0,0)}}} \LongitudePlane[xzplane]{\angEl}{\angAz} % sphere \filldraw[ball color=blue, opacity=.2] (0,0) circle (\R); %\draw[xyplane] (-2*\R,-2*\R) rectangle (2.2*\R,2.8*\R); \draw[xyplane,->] (-2.25*\R,0) -- (2.75*\R,0) node[below right] {$k_x$}; \draw[xyplane,->] (0, -1.1*\R)-- (0,1.5*\R) node[below left] {$k_y$}; \draw[->] (0,-1.25*\R) -- (0,1.5*\R) node[below right] {$k_z$}; % meridians \foreach \t in {-80,-60,...,80} { \DrawLatitudeCircle[\R]{\t} } \foreach \t in {-5,-35,...,-175} { \DrawLongitudeCircle[\R]{\t} } \end{tikzpicture} \end{document} Which I got from this paper which refers to this TeXample from which I got the above projected drawing code. I unfortunately do not see a way to properly turn this into a sliced sphere or hemisphere at the least. As an additional improvement, perhaps the inside of the sphere can be "dark-shaded", such that the result looks like what I can do "easily" with Mathematica: I understand the above needs some work wrt the line color and all, but what interests me here is the sectioning and the shading of the inside of the sphere. I would guess some handy clip action and two ball shadings with different opacities might get me close, but I have no idea how to get the clipping to work. Thanks!

I want to draw a section of a sphere to represent its volume. I have currently got the following: \documentclass{article} \usepackage{pgfplots} \pgfplotsset{compat=1.11} \begin{document} \begin{tikzpicture} \begin{axis}[ axis equal, axis lines = center, width = 10cm, height = 10cm, xlabel = {$x$}, ylabel = {$y$}, zlabel = {$z$}, view/h=45, ] \addplot3[surf, opacity = 0.5, samples=21, domain=0:1, y domain=0:0.5*pi, z buffer=sort] ({sqrt(1-x^2) * cos(deg(y))}, {sqrt( 1-x^2 ) * sin(deg(y))}, x); \end{axis} \end{tikzpicture} \end{document} Which gives me: But I want the sides to be closed, something like this: How can I do this?

I want to draw 3D shapes in latex. I have tried out different strategies, but nothing has led me to a good solution yet. First what I want to do, then what I have done so far. In prioritized order, these are my constraints: Output (the figure) must be vector graphics I would REALLY like to compile my main document with pdflatex Text should preferably be scalable, i.e., the text stays the same, even if I decide to make the figure bigger in my document. Objects should have a shading that makes them look like they are lighted from somewhere (otherwise I cannot distinguish between a circle and a sphere). I want to use colors defined in my main files preamble - thus dynamic use of main file's preamble content (this is in an individual file). This is probably not possible at the same time, but a trade off is welcome. What works for you when drawing 3D objects? My progress so far I've made friends with Tikz, but when familiarizing myself with its shortcomings (such as 3d solids it seems), I've flirted with PStricks - but this was a messy first date, so unless you guys REALLY advocate her as a part of the solution, I'd rather stay with Tikz (but hey, beggars can't be choosers). I've made a MWE, where everything is included (in my case it is split in many different files (a PhD-thesis becomes quite large, after all). This is the code that generates a sphere using the trick of implementing the "ball", which is not inherent 3D: \documentclass{standalone} \usepackage{pgfplots} \pgfplotsset{compat=1.4} \usepackage{tikz-3dplot} \tdplotsetmaincoords{60}{-30} \tdplotsetrotatedcoords{0}{90}{90}% %\usepackage[rgb]{xcolor} \definecolor{c1}{rgb}{0.2,0.4,0.6} % Blue-ish \definecolor{c2}{rgb}{1.0,0.0,0.6} % Pink-is \definecolor{c3}{rgb}{0.6,0.0,0.0} % Red \begin{document} \begin{tikzpicture} [tdplot_rotated_coords, scale=3, cube/.style={color=c1,thick,draw=gray, fill opacity=0.5,line join=round}, mds/.style={ball color=c2, c2, opacity=.8}, helplines/.style={gray,line cap=round}, length/.style={<->,thick,line cap=round}, axis/.style={->,c3,ultra thick,line cap=round}, textlabel/.style={fill opacity=.7,text opacity=1,fill=white,rounded corners}] \def\d{1} \def\r{\d*.45} \def\af{\d*.5} % Draw backside of the cube \fill[cube] (0,0,\d) -- (0,\d,\d) -- (\d,\d,\d) -- (\d,0,\d) -- cycle; \fill[cube] (0,0,0) -- (0,0,\d) -- (\d,0,\d) -- (\d,0,0) -- cycle; \fill[cube] (\d,0,0) -- (\d,0,\d) -- (\d,\d,\d) -- (\d,\d,0) -- cycle; % Draw helplines \foreach \t in {0,12,...,348} % circle \draw[helplines] ({cos(\t )*\r+\d/2}, \d/2, {sin(\t )*\r+\d/2}) -- ({cos(\t+12)*\r+\d/2}, \d/2, {sin(\t+12)*\r+\d/2}); \draw[helplines] (\d/2,\d/2-\r,\d/2) -- (\d/2,\d/2+\r,\d/2); % vertical line % Cylinder \shade[mds] (\d/2,\d/2,\d/2) circle (\r cm); % <= the little " cm" is needed to "trick" (?) everything into working... % Draw front of cube \fill[cube,fill=none] (0,0,0) -- (0,\d,0) -- (\d,\d,0) -- (\d,0,0) -- cycle; \fill[cube,fill=none] (0,\d,0) -- (0,\d,\d) -- (\d,\d,\d) -- (\d,\d,0) -- cycle; \fill[cube,fill=none] (0,0,0) -- (0,0,\d) -- (0,\d,\d) -- (0,\d,0) -- cycle; % Draw the axis arrows and annotations \draw[axis] (0,0,0) -- (\af,0,0) node[textlabel,anchor=east]{$x$}; \draw[axis] (0,0,0) -- (0,\af,0) node[textlabel,anchor=south]{$y$}; \draw[axis] (0,0,0) -- (0,0,\af) node[textlabel,anchor=west]{$z$}; % Draw radius arrow \draw[mds,length,draw] (\d/2,\d/2,\d/2) -- (\d/2,\d/2,\d/2+\r) node[textlabel,pos=0.5, auto=above]{$r$}; % Draw cube lattice length measures \draw[cube,length,c1] (0,0,\d*5/6) -- (0,\d,\d*5/6) node[textlabel,pos=0.5, auto=above]{$d$}; \draw[cube,length,c1] (\d*5/6,0,0) -- (\d*5/6,\d,0) node[textlabel,pos=0.5, auto=above]{$d$}; \draw[cube,length,c1] (\d*5/6,\d,0) -- (\d*5/6,\d,\d) node[textlabel,pos=0.5, auto=above]{$d$}; % Material parameters label \draw[mds] (\d/2,\d/2+\r/2,\d/2) node[textlabel]{$\varepsilon_c,\mu_c$}; \end{tikzpicture} \end{document} Which produces: I have worked on some code for manually coding a cylinder, but I encounter two main problems: I cannot dynamically change the fill, to create a shading effect.
