TikZ

I was looking at Use "plot" inside a \draw path in tikz. I want to fill such a region, and improve my (very inconvenient currently) syntax. Is it possible to do cycle in a way like this too? \documentclass[border=1cm]{standalone} \usepackage{tikz} \usetikzlibrary{calc} \begin{document} \begin{tikzpicture}[trig format=rad] \draw (0,1) coordinate (T0) -- (1,1) coordinate (T1) [shift={(T1)}] plot[domain=0:2*pi] (\x,{sin(\x)}) coordinate (T2) [shift={($(T1) + (T2)$)}] (0,0) -- (1,0) coordinate (T3) [shift={(T3)}] (0,0) -- (1,3) coordinate (T4) [shift={(T4)}] plot[domain=0:pi] (-2*\x,{sin(\x)}) coordinate (T5) [shift={($(T4) + (T5)$)}] plot[domain=0:1] (-\x,\x) [shift= {(T0)}] -- (0,0) ; \end{tikzpicture} \end{document}

I'm a teacher and for my tests, I have a template like that : \documentclass[11.5pt, oneside]{report} \usepackage{tikz} \RequirePackage{geometry} \geometry{a4paper,left=1.5cm,top=2.5cm,right=1.5cm,bottom=1cm} \begin{document} \begin{minipage}{0.60\linewidth} \begin{flushleft} \large NAME : {\dotfill} \\ \vspace{0.3cm} Forname : {\dotfill} \end{flushleft} \end{minipage} \hfill \begin{minipage}{0.15\linewidth} \begin{flushright} \large class \\ \vspace{0.3cm} date \end{flushright} \end{minipage} \vspace{0.5cm} \begin{center} {\Large \textbf{Contrôle number : test name}} \medbreak {\Large Sujet A} \medbreak {\Large Durée : duration.} \end{center} \vspace{0.5cm} \begin{tikzpicture} \draw[thick] (0,0)--(18,0)--(18,2.5)--(0,2.5)--cycle; \draw[thick] (0,0)--(2.5,2.5)--(2.5,0); \draw (1.8,0.7) node{\Huge maxgrade}; \end{tikzpicture} \end{document} I created a documentclass for my tests but I would like to find a way to define the date, the class, the number and name of the test, the duration of the test and the maximum grade and have them automatically be implemented in that way without having all those lines that make it hard to see and to modify. Does anyone have any idea of how I could do that?

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.

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?

I would like to realize the following image in TikZ, which I had created very roughly in Adobe Illustrator. I am interested in understanding how to use TikZ 3d canvas to squash vectors along planes or lines. I would also like to see how it is used for labels. Here my attempt.

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}

I don't quite understand why the first node is no longer pointing toward $C_0$. How can I move $C_0$ to be on the far right side, still level with the first node (kind of looking like a trapezoid) while still connected to the first node? \documentclass{article} \usepackage{tikz} \usetikzlibrary{graphs} \begin{document} \begin{center} \scalebox{1.2}{ \tikz \graph [grow right sep]{ x1 [as =$\displaystyle \int_a^b{f(x)dx}$] -> {x2[as=$C_0$, red], x3[as=$F(t)$] -> x4[as=$F^\prime(t)$] -> x5[as=$\displaystyle \int{F^\prime(t)dt}$] -> x6[as=$C(t) + C_{1}$, red]->x2}; }; } \end{center} \end{document} This is what it currently looks like: This is the intended result (essentially, ignore the terrible drawing lol): Any help or a push toward some sort of useful resource is much appreciated.

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 was plot the flowchart as below with the MWE: \documentclass[border=8pt,tikz]{standalone} \usetikzlibrary{positioning} \begin{document} \begin{tikzpicture}[ cap = round, every rectangle node/.style = {draw,outer sep=0pt,minimum width=2cm}, empty/.style = {circle,inner sep=0pt,outer sep=0pt,minimum size=0pt}] \node[rectangle] (A) {input $x$}; \node[empty] (B) [right=1 of A] {}; \node[rectangle] (C) [above right=.3 and 3 of A] {$\frac15x$}; \node[rectangle] (D) [below right=.3 and 3 of A] {$x+4$}; \node[empty] (E) [right=5.5 of A] {}; \node[rectangle] (F) [right=1.5 of E] {output}; \node[empty] (F1) [below=1.2 of F] {}; \node[empty] (F2) [below=1.2 of A] {}; \draw[-latex] (A) -- (B) |- node [empty,sloped,pos=.75,above=-.2] {$x\ne1$} (C); \draw[-latex] (B) |- node [empty,sloped,pos=.75,below=-.2] {$x=1$} (D); \draw[-latex] (C) -| (E) (D) -| (E) -- (F); \draw[-latex] (F) -- (F1) -- node[empty,sloped,below=-.2] {$x<99$} (F2) -- (A); \end{tikzpicture} \end{document} However, I found that the Horizontal and Vertical Lines Operation |- and -| reached a limited function as the document below shown: In my above code: I have the following three questions: \draw[-latex] (A) -- (B) |- node [empty,sloped,pos=.75,above=-.2] {$x\ne1$} (C); \draw[-latex] (B) |- node [empty,sloped,pos=.75,below=-.2] {$x=1$} (D); \draw[-latex] (C) -| (E) (D) -| (E) -- (F); \draw[-latex] (F) -- (F1) -- node[empty,sloped,below=-.2] {$x<99$} (F2) -- (A); the code above of FOUR \draw of FOUR arrows is a little superfluous, but the arrow is based on \path Is there any tune of my code to avoid defining the node of (B) and (E) explicitly in my case, what I want is a more powerful |- and -| provide a parameter such as proportion=<fp in 0~1> which decide the horizonal/vertical length of the conjunction automatically In the framework of TikZ, is there exists better solution to plot flowchart like this without immersed in multiple seperate \path operation?

I am trying to use the canvas system to define scopes with local planes. When defining a local plane, according to the documentation we define: plane origin=⟨point⟩ Origin of the plane plane x=⟨point⟩ Unit vector of the x-direction in the new plane plane y=⟨point⟩ Unit vector of the y-direction in the new plane So the default plane (in 3D) should be : plane origin = (0,0,0), plane x = (1,0,0), plane y = (0,1,0) If I run this code, I should get a green vector corresponding to the x direction starting from the origin, and the same vector in red starting from (0,3): \documentclass[tikz,border=3.14mm]{standalone} \begin{document} \usetikzlibrary {3d, angles, calc, patterns, quotes, math} \begin{tikzpicture} \draw[->,green] (0,0,0) -- (1,0,0) node[right] {$\vec u_x$}; \begin{scope}[plane x = {(1,0,0)}, plane y = {(0,1,0)}, plane origin = {(0,3,0)}, canvas is plane, transform shape]; \draw[->,red] (0,0) -- (1,0) ; \end{scope} \end{tikzpicture} \end{document} But I get this and I can't figure out why (3D/2D conversions... ??)

I am trying to draw the latex picture as same as shown in the given image. Almost all I have done but I am unable to draw the axis label as shown in the image. Please anyone can help me? \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}[ view={60}{30}, axis lines=none, % Draw axes lines samples=30, samples y=10, domain=0:360, xmax=20, ymax=20, zmax=20, grid=major, enlargelimits=true, axis on top, shader=flat, opacity=1.0, colormap={gray}{color(0cm)=(lightgray); color(1cm)=(lightgray)}, xtick=\empty, % Remove x-axis ticks ytick=\empty, % Remove y-axis ticks ztick=\empty % Remove z-axis ticks ] % Upper cone z = sqrt(x^2 + y^2) \addplot3 [ surf, faceted color=black, % Color of the grid lines draw=black, % Draw the edges with black lines z buffer=sort, domain=0:360, y domain=0:10, ] ({y*cos(x)},{y*sin(x)},{y}); % Lower cone z = -sqrt(x^2 + y^2) \addplot3 [ surf, faceted color=black, % Color of the grid lines draw=black, % Draw the edges with black lines z buffer=sort, domain=0:360, y domain=0:10, ] ({y*cos(x)},{y*sin(x)},{-y}); \end{axis} \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). Here's my code: \documentclass{article} \usepackage{bodeplot} \begin{document} \BodeTF{num/{0,1},den/{1,1},d/0}{0.01}{100} \end{document} Gain plot seems ok - phase plot doesn't show expected (i. e.: NOTHING! Plus giving errors). What am I doing wrong? === EDIT 26-SEP-2023 === In Overleaf it works fine, using TexLive 2023. Just updated my MikTeX installation on my desktop PC - still no phase plot.

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?

Please find below a MWE. (Un-)commenting \usetheme{metropolis} removes content from the tikzpicture, and I am truly puzzled as to why that is. I am using XeLaTeX to compile. Thanks! \documentclass[xcolor=dvipsnames,aspectratio=149,10pt]{beamer} \usepackage{pgf,tikz,pgfplots,tikz-cd} \pgfplotsset{compat=1.15} \usepackage{mathrsfs} \usetikzlibrary{arrows,intersections, pgfplots.fillbetween} \usetheme{metropolis} \begin{document} \begin{frame} \begin{tikzpicture}[line cap=round,line join=round,>=triangle 45,x=5.0cm,y=5.0cm,scale=0.45] \begin{axis}[ x=5.0cm,y=5.0cm, xmin=-1.0, xmax=1.0, ymin=-1.0, ymax=1.0, xtick={-0.5,0.0,0.5}, ytick={-0.5,0.0,0.5}, xticklabels={,,}, yticklabels={,,}, line width= 2pt ] \clip(-1.,-1.) rectangle (1.,1.); \draw [line width=1.25pt] (-1,1.)-- (1,-1.); \draw [->,>=stealth,line width=1.pt,dash pattern=on 2pt off 2pt] (-0.4,0.4-0.25)-- (-0.4,0.4+0.25); \draw [->,>=stealth,line width=1.pt,dash pattern=on 2pt off 2pt] (-0.4-0.25,0.4)-- (-0.4+0.25,0.4); \draw [->,>=stealth,line width=1.pt,dash pattern=on 2pt off 2pt] (0.4,-0.4+0.25) -- (0.4,-0.4-0.25); \draw [->,>=stealth,line width=1.pt,dash pattern=on 2pt off 2pt] (0.4+0.25,-0.4) -- (0.4-0.25,-0.4); \end{axis} \end{tikzpicture} \end{frame} \end{document}

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.

I am making a presentation and I want to recall some pictures in my conclusion. The pictures are done using tikzpicture and are in separate files, with some overlay specifications. However, I want to recall only a specific overlay in the conclusion. File: picture.tex \begin{tikzpicture} \draw at (0,0) circle (1); \uncover<2->{ \draw at (2,0) circle (1);} \uncover<3->{ \draw at (1,1) circle (1);} \end{tikzpicture} Then in my main file, \documentclass{beamer} \usepackage{amsmath} \usepackage{tikz} \begin{document} \frame{\frametitle{The Picture} Some text \begin{center} \input{picture} \end{center} } \frame{\frametitle{Conclusion} \begin{center} \input{picture} \end{center} } I would like to display only the overlay <2> in the conclusion without recalling the whole frame (with \againframe). Is there any way of doing that or should I create another file with only what I want to display on the last frame?

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.

Thank you so much for taking the time to read this LOOOONG question.

Problem This is a shameless "just do it for me" graphics question, but honestly I have no idea where to start. I'd like to reproduce this figure The image shows the intersection of two surfaces of constant gibbs energy.

Usage of tikz-3dplot is not required. Feel free to downvote or vote for closing this question, as it is a shameless "just do it for me" question. I'm bad and I should feel bad!
