TikZ

I want a one cm offset between the blue path and the black one. \documentclass[tikz,margin=1cm]{standalone} \begin{document} \begin{tikzpicture} \draw[gray!50] (-8,0) grid (8,-8); \fill (0,0) node[above=12pt]{origin} circle (5pt); \draw[ultra thick] (-6,0) arc[x radius=12,y radius=8,start angle=90,end angle=0] -- (-6,-8) -- cycle; \draw[blue,ultra thick] (-5,-1) arc[x radius=10,y radius=6,start angle=90,end angle=0] -- (-5,-7) -- cycle; \end{tikzpicture} \end{document} Note: Both must be similar. Right now both are not similar.

I would like to draw a line starting from the point (200, 105.6), perpendicular to the failure envelope, and extending down to intersect the x-axis.

I have a mono-spaced font (TeX Gyre Cursor), but when I use it in a Tikz node with text width = XYcm the spaces change size. Is there a way to either preserve the space size with the width command, or achieve automatic line breaks in tikz node in some other way that does not break the spaces? Additionally, when using alignemnt, it inserts an indent at the start of the text, which I was not able to remove with \setlength{parindent}{0pt}. What causes this indent and how can I remove it? Here is my full node code: \node at (3, 1.75) [ align = left, text width = 4.6cm, ] {\setlength{\parindent}{0pt}\textbf{\setfontsz{\sztext} Text line 1, Longer text line 2, Even way way way way longer text line 3, Text line 4}}; EDIT: here is the full code: \documentclass{article} \usepackage[paperheight=8cm, paperwidth=6cm, left=0pt, top=0pt, right=0pt, bottom=0pt]{geometry} \usepackage{tikz} \usepackage{fontspec} \usepackage{array} \setmainfont{TeX Gyre Cursor} \newcolumntype{P}[1]{>{\centering\arraybackslash}p{#1}} %% horizontal centering \newcommand{\setfontsz}[1]{ \fontsize{#1}{1.2#1} \selectfont } \pagestyle{empty} %\renewcommand{\arraystretch}{2.2} \newcommand{\sztext}{8pt} \begin{document} %\vspace*{-\baselineskip} \begin{tikzpicture}[remember picture, overlay, shift = {(current page.south west)}] \node at (current page.center) [] {\includegraphics[height=\paperheight]{example-image-a.png}}; \node at (3, 1.75) [ align = left, text width = 4.6cm, ] {\setlength{\parindent}{0pt}\textbf{\setfontsz{\sztext} Text line 1, Longer text line 2, Even way way way way longer text line 3, Text line 4}}; \end{tikzpicture} \end{document}

I am using CircuitTikZ and often need to connect wires or labels to component anchors. However, it is not always easy to know which anchors are available for a specific component. For example, different components may provide anchors such as north, south, in, out, gate, collector, emitter, etc., and the available anchors vary depending on the component type. When building more complicated schematics, I frequently need to stop and search through the documentation to check anchor names. I was wondering whether there is a way to programmatically: List all available anchors of a given CircuitTikZ/TikZ shape/components, and/or Visualize those anchors directly on the rendered component. For example, something conceptually like: \showanchors{a component/shape} that would either print all anchor names and draw markers/labels on the component itself. So my question is: Is there a practical way to list all anchors associated with a TikZ/CircuitTikZ shape? My motivation is mainly usability and workflow efficiency. A tool like this would make it much easier to explore unfamiliar components and reduce the need to constantly check the manual, especially for beginners or occasional CircuitTikZ users. This is an example of visualizing the anchors to help wiring from CircuiTikz documentation. A possible MWE (clearly, the pin thing must be adjusted somehow to have a better distribution, and to take into account that labels can have spaces and strange characters, but well...). The task it to substitute the \allanchors definition with something automatic, see the comment above it. \documentclass[border=10pt]{standalone} \usepackage[T1]{fontenc} \usepackage[siunitx, RPvoltages]{circuitikz} \begin{document} \begin{tikzpicture}[every pin/.append style={text=red, inner sep=1pt, font=\tiny\ttfamily}] \node [npn](myshape) at (0,0) {}; % Example: this should be autofilled % Basically, for every shape named, say, "gizmo", the anchor "spot" % is a macro named pgf@anchor@gizmo@spot % --- so to do what you want, you should be able to find all % the macros with that pattern that exist % (and I do not know if this is possible in TeX in general, % maybe in LuaTeX...). \newcommand{\allanchors}{center,E,B,south} \foreach \anc in \allanchors { \node[circ, pin=45:\anc] at (myshape.\anc) {}; } \end{tikzpicture} \end{document}

I have this MWE (it must be zoomed in on): I want the red line to go all the way to the green one on the top, but not exceed the dark gray on the bottom. Likewise, the green should be bounded by, and extruded to the boundary also. (The green one goes beyone on top, but we just can't see it due to the ligh gray triangle occluding it). I would like for this to be as automatic as possible. I want it to look like this: This is my use case: \documentclass[tikz,border=1cm]{standalone} \begin{document} \begin{tikzpicture} \fill[gray] (0,0) -- (1,1) -- (1,0) -- cycle; \draw[thick,green] (0.75,0.25) -- (0.25,0.25); \fill[gray!50!white] (0,0) -- (1,1) -- (0,1) -- cycle; \draw[thick,red] (0.1,0.25) -- (0.25,0.25); \end{tikzpicture} \end{document}

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 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?

I want to create a perfect monochrome Periodic table (for black and white printing, etc.). 1/2. Instead of the colored "radioactive symbol" (which seems to be set hard-coded by the package), I'd like to use an asterisk '*' or a simple text character. 2/2. Secondly, the term 'Ra' in the legend must also be replaced by the star (or the other symbol used). Note: The aforementioned "radioactive symbol" seems to be (hard-coded) retrieved from the file /texmf-dist/tex/latex/pgf-periodictable/pgfPT_radio_symbol.pdf → which is located near the package file. One could therefore "hack" the problem by placing a PDF file with the same name in one's working directory. However, I'm wondering if there's a more elegant solution. PS: Since I'm not yet very familiar with the package, general suggestions for improvement are welcome.

I need to draw a pulley system as in the figure. How can I do that? Specific information about the figure: A block of mass Mo is on a horizontal surface and attached by a string to a hanging block, also of mass Mo , as shown in the figure. Friction between the block and the horizontal surface is negligible. The masses of the string and pulley are negligible, and the pulley can rotate with negligible friction around its axle.

I need to draw two concentric circles plus additional circles that the mutually tangent, like this: I tried using \draw (0,0) arc [radius=1, start angle=-30, end angle= 60]; \draw (0,0) arc [radius=3, start angle=-30, end angle= 60]; to draw the concentric arcs, but it seems that the "(0,0)" specify the starting point and not the center of the arc. Eventually I hacked together an ad hoc tikz code to make this picture (see below), but I wonder if there is a more standard/non-adhoc ways to do this? E.g. is there a way to get tizk to polar polar graphs directly? BONUS Q: How do I color the wedge bounded by the two line segments and the outer arc? Thanks!

basically the problem is the same as in a question i previously asked: Draw shaded region using tikz and pgfplots Now the problem is that the region i want to draw is more complicated, mainly because of the functions involved: This is what i want to obtain, but i don't know how to change the code in the answer in order to draw the graph showed in the image, also because tikz does not really get along with sqrt function. Does anyone know how to solve my problem?

I am trying to draw the following region The best i can do is the following code: \begin{figure}[H] \begin{center} \begin{tikzpicture} \begin{axis} [ axis lines = middle, xlabel={$x$}, ylabel={$y$}, xmin=-1, xmax=2, ymin=0, ymax=3, xmajorticks=false ] \addplot[smooth, thick, samples=200, name path=curve1] {1/(2*x)}; \addplot[smooth, thick, samples=200, name path=curve2] {1/x}; \addplot[smooth, thick, samples=200, name path=curve3] {2*x^2}; \addplot[smooth, thick, samples=200, name path=curve4] {3*x^2}; \addplot[color=black,fill=pink,fill opacity=0.4]fill between[of=curve1 and curve2, soft clip={domain=0.5503:0.7937}]; \end{axis} \end{tikzpicture} \end{center} \end{figure} Which creates the following image: Can someone help me? Because i don't know how to use the functions y=1/2x and y=1/x as a border to the shaded region.

My question I can easily draw the normal distribution thanks to this answer by Jake. What about the ghost ? Context This image always breaks the ice when teaching probabilities 🙂 (Not that I care so much about it, but Halloween is getting closer too) I presume it would be possible with Inkscape (but I am not familiar with it). This answer by Paul Gaborit uses the hobby package I tried to adapt (poorly as you'll see, far too manual to be honnest) in my MWE. I'd be happy to see different approaches too (pure tikz, pgfplot, other libraries...). \documentclass[tikz]{standalone} \usetikzlibrary{hobby} \usetikzlibrary{calc} \begin{document} \begin{tikzpicture}[use Hobby shortcut] \draw[ help lines, line width=0.1pt, blue, ] (-20, -20) grid[step={($(5, 5) - (0, 0)$)}] (60, 100); \path (0,0) coordinate (z0) (10,10) coordinate (z1) (20,0) coordinate (z2) (30,10) coordinate (z3) (40,0) coordinate (z4) (50,10) coordinate (z5) (30,90) coordinate (z6) (0,70) coordinate (z7) (0,60) coordinate (z8) ; \draw[closed,black, line width= 3mm] (z0) ..

How to draw intersect of line sphere?

I would like to create a wiki (several authors) with scientific content, including text, equations, graphs and schemes. I wish to use LaTeX macros (including my own ones) and draw graphics with the powerful PGF/Tikz syntax. My aim is to minimize the work to turn a .tex file into a wiki page, and to keep code flexibility (ideal case would be to copy/paste raw .tex file content in a wiki page and the server should render it). Is Mediawiki able to do that? Is it possible to approach similar behavior with latex2html? Any feedback would be welcome! Thanks

Running the following in LaTeXiT preamble: \documentclass[10pt]{article} \usepackage[usenames]{color} %used for font color \usepackage{amssymb} %maths \usepackage{amsmath} %maths \usepackage[utf8]{inputenc} %useful to type directly diacritic characters \usepackage{tikz} body \begin{tikzpicture} \draw (1.5,1.5) circle [radius=1.5]; \end{tikzpicture} produced the following picture When I right-clicked on it, and chose "Get Info" it says that it has dimensions 618 × 620. My questions are: how come such a symmetric shape resulted in uneven dimensions? Is there a way to predict the image dimensions from the TikZ parameters (e.g. radius)? Is there a natural way to get a circle with equal dimensions in TikZ? Thanks.

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.

Often I see in a paper a table with a column of circles which are filled for 25/50/75/100% to show priority/level of meeting requirements, to mention yes/no/unknown/NA etc? Do such (usage of) circles have a specific name? How can I add such circles to a table in an easy way? What are common other (visualization) techniques used in scientific papers to visualize this kind of levels/ranking/categorization? So far I have seen these circles and ++ .. --. But I am novice so maybe there are more techniques. Thanks

I have gone through the comprehensive symbols in LaTeX that provides some animals icons but not enough for fun documents. One of my math questions requires the illustration as follows, which is a repeated list of ducks and turtles: Could you help to draw these animals using Tikz?

I made this commands to make paper models, and I ask if it is possible to have a 3D view of them converting in tikz-3D, or backward. But it's easier to draw the flat model and generate the volume after. Calculations could be made with lualatex.

In his answer to Cylinder shading with PGF/TikZ, Jake provides a code to draw a shaded cylinder with a not shaded top. This code draws a cylinder node (from shapes.geometric library) and after that, with a second draw command, an ellipse is drawn over it. I've tried to join both steps within a mycylinder/.style with an append after command option without any success. I still don't completely understand what \pgfinterruptpath, \pgfextra do, so may be my code is not correct. I imagine that covering ellipse must be drawn after shading the cylinder but I don't know how to do it. Could you explain what's wrong? \documentclass[tikz,border=1mm]{standalone} \usetikzlibrary{calc,fit,backgrounds,positioning,arrows,shapes.geometric} \begin{document} \begin{tikzpicture}[font=\sffamily\small, >=stealth', mycylinder/.style={ draw, shape=cylinder, alias=cyl, % Will be used by the ellipse to reference the cylinder aspect=1.5, minimum height=3cm, minimum width=2cm, left color=blue!30, right color=blue!60, middle color=blue!10, % Has to be called after left color and middle color outer sep=-0.5\pgflinewidth, % to make sure the ellipse does not draw over the lines shape border rotate=90, append after command={% \pgfextra{% \pgfinterruptpath % \begin{pgfonlayer}{foreground layer} \fill [blue!10] let \p1 = ($(\tikzlastnode.before top)!0.5!
