TikZ

how to create a calendar like the attached photo. in particular how to: combine days like may 24/31 so that one month's calendar always fits on 5 rows, and how to put items (e.g. mini calendar for previous and successive months, photo, or lunar phases) in the boxes that aren't days

I am designing a square (or “squarish” actually) map protractor in TikZ. So far, I have managed to draw the degree ticks along the four sides by clipping radial lines between two closed paths using the even odd rule like I saw in this answer. The ticks are generated in a \foreach loop. To avoid drawing long ticks on top of short ones, I separated them into two loops using a conditional test. I am not sure whether this separation is actually necessary for correct SVG export/printing, but that is how I implemented it. Below is a MWE: \documentclass[tikz]{standalone} %,convert={outfile=\main.svg} \usepackage{pgfplots} \pgfplotsset{compat=newest} \usetikzlibrary{intersections, pgfplots.fillbetween} \pgfdeclarelayer{pre main} \pgfdeclarelayer{main} \pgfsetlayers{pre main, main} \usetikzlibrary{shapes} \begin{document} %all of this is needed to easily clip between two closed paths using even odd rule \makeatletter \def\@appendnamedsoftpath#1{% \pgfsyssoftpath@getcurrentpath\@temppatha \expandafter\let\expandafter\@temppathb\csname tikz@intersect@path@name@#1\endcsname \expandafter\expandafter\expandafter\def\expandafter\expandafter\expandafter\@temppatha\expandafter\expandafter\expandafter{\expandafter\@temppatha\@temppathb}% \pgfsyssoftpath@setcurrentpath\@temppatha } \def\@appendnamedpathforactions#1{% \pgfsyssoftpath@getcurrentpath\@temppatha \expandafter\let\expandafter\@temppathb\csname tikz@intersect@path@name@#1\endcsname \expandafter\def\expandafter\@temppatha\expandafter{\csname @temppatha\expandafter\endcsname\@temppathb}% \let\tikz@actions@path\@temppatha } \tikzset{ use path for main/.code={% \tikz@addmode{% \expandafter\pgfsyssoftpath@setcurrentpath\csname tikz@intersect@path@name@#1\endcsname }% }, append path for main/.code={% \tikz@addmode{% \@appendnamedsoftpath{#1}% }% }, use path for actions/.code={% \expandafter\def\expandafter\tikz@preactions\expandafter{\tikz@preactions\expandafter\let\expandafter\tikz@actions@path\csname tikz@intersect@path@name@#1\endcsname}% }, append path for actions/.code={% \expandafter\def\expandafter\tikz@preactions\expandafter{\tikz@preactions \@appendnamedpathforactions{#1}}% }, use path/.style={% use path for main=#1, use path for actions=#1, }, append path/.style={% append path for main=#1, append path for actions=#1 } } \makeatother \begin{tikzpicture} \pgfmathsetmacro\bigside{7} \pgfmathsetmacro\smallsidedelta{0.5} %cuts \draw[rounded corners=12pt, name path=outside] (0,0) rectangle (\bigside,\bigside); \draw[dotted, rounded corners=12pt, name path=inside] (\smallsidedelta,\smallsidedelta) rectangle (\bigside-\smallsidedelta,\bigside-\smallsidedelta); %remove before cutting or printign.

When numbers get big, they don't have enough space to fit unless the labels become too small to read (actual printing size of the protractor will be something like 7x7 or 8x8cm). So they need to be shifted in such a way that they fit. 355 in the provided image is a clear example of what I mean. I can consider shifting them radially as well, but they need to stay to the outside of the dotted line, which I can make a little smaller. I really don't know where to start and didn't manage to find anything online. Thank you for your time!

The question arised from the previous link and the luadraw solution. I am using luadraw to visualize the surface z = x^2 + y^2 together with the intersection curve corresponding to the direction u = (1,0). I would like to know whether it is possible to: Label the coordinate axes $x$, $y$, and $z$, Label the point $c = (0,0)$, Indicate the direction $u = (1,0)$, And label the function $F(t) = t^2$ corresponding to the intersection curve. When I try to use Dtext3d, the document compiles but the output appears blank in Overleaf. Is there a reliable way to add these labels when using luadraw? \documentclass[border=5pt]{standalone} \usepackage[svgnames]{xcolor} \usepackage[3d]{luadraw} \usepackage{fourier-otf} \usepackage{tikz} \begin{document} \begin{luadraw}{name=paraboloid} local g = graph3d:new{ window3d = {-2,2,-2,2,0,8}, window = {-4.5,4,-3,9.5}, size = {10,10,0}, viewdir = perspective("central",30,50,20) } -- Surface local S = cartesian3d(function(x,y) return x^2+y^2 end, 2,-2,-2,2) -- Direction local c = Origin local u = M(1,0,0) local N = pt3d.prod(u, vecK) -- Intersection curve local Curve = g:Intersection3d(S, {c,N}) -- Draw surface g:Dfacet(S, {usepalette={palGasFlame,"z"}, edgecolor="gray", clip=true}) -- Draw curve g:Dedges(Curve, {hidden=true, color="Navy", width=12}) -- Axes g:Dline3d({Origin, M(2,0,0)}, {color="black", width=1, dash="dotted"}) g:Dline3d({Origin, M(0,2,0)}, {color="black", width=1, dash="dotted"}) g:Dline3d({Origin, M(0,0,6)}, {color="black", width=1, dash="dotted"}) g:Show() \end{luadraw} % ---- 2D overlay labels (safe in Overleaf) ---- \begin{tikzpicture}[overlay] \node at (3.7,4.2) {$x$}; \node at (1.1,4.8) {$y$}; \node at (2.5,7.3) {$z$}; \end{tikzpicture} \end{document}

I want to draw this shape using TikZ, but I don't know how. Could anyone provide an example of how to do it?

how do i get a list that has a heading (in this example, "Deep Learning Methods" as the heading), from which level-2 entries are connected with solid lines? so far i draw the connector lines with tikz like this: which looks fine except for the extra-bolded trunk of the tree due to multiple retracing of the same connector path in my current implementation. it is super-subtle, but when you zoom out of the PDF file, you can see marginal pixel strips lacking at the upper part of the tree trunk where it's thinner than the rest. the MRE is as follows: \documentclass{article} \usepackage{tikz} \usetikzlibrary{tikzmark,calc} \tikzset{ taxonomy/.style={ overlay, remember picture } } \newcommand{\subcatindent}{1.3em} \newcommand{\methodsindent}{2.3em} \begin{document} unrelated text\\ \textbf{\tikzmarknode{dl}{\underline{Deep Learning Methods}}}\\ \hspace*{\subcatindent}\textbf{\tikzmarknode{dl_convo}{Convolution}}\\ \hspace*{\methodsindent}AE-based\\ \hspace*{\subcatindent}\textbf{\tikzmarknode{dl_ae}{Autoencoders}}\\ \hspace*{\methodsindent}Method D2\\ \hspace*{\subcatindent}\textbf{\tikzmarknode{dl_gan}{GANs}}\\ \hspace*{\methodsindent}Method D3\\ \hspace*{\subcatindent}\textbf{\tikzmarknode{dl_diff}{Diffusion}}\\ \hspace*{\methodsindent}Method D3\\ \hspace*{\subcatindent}\textbf{\tikzmarknode{dl_att}{Attention-Driven}}\\ \hspace*{\methodsindent}Method D3\\ \hspace*{\subcatindent}\textbf{\tikzmarknode{dl_ens}{Ensemble}}\\ \hspace*{\methodsindent}Method D3 \begin{tikzpicture}[taxonomy] \newcommand{\srcOffsetX}{+0.3em} \newcommand{\srcOffsetY}{-1.0ex} \coordinate (dl_start) at ($(dl.south west)+(\srcOffsetX,\srcOffsetY + 0.3ex)$); \coordinate (dl_lowest) at (dl_ens.west); \coordinate (dl_trunk) at ($(dl_start |- dl_lowest)$); \draw (dl_start) -- (dl_trunk); \draw (dl_trunk) |- (dl_convo.west); \draw (dl_trunk) |- (dl_ae.west); \draw (dl_trunk) |- (dl_gan.west); \draw (dl_trunk) |- (dl_diff.west); \draw (dl_trunk) |- (dl_att.west); \draw (dl_trunk) |- (dl_ens.west); \end{tikzpicture} \end{document} is there a way to dynamically and systematically implement this so that the connectors are drawn exactly at the place where the previous one turned 90 degrees to the right? ideally, i could turn this in a custom list environment, but so far i don't see a clear way of solving the retracing problem.

I would like to create "half letters" that attach to the left side of letters in a math formula. This would not only allow for the Latin AE character, but also characters like AD, OP, TB, and so on. When using regular Tikz lines, the attachment to the left side of the main letter does not appear to have the same font as the right side. For example, I will merge A and P together: \begin{tikzpicture} \draw[x=1pt,y=1pt,xshift=1.2] (5.3,3.6) node[node font=\itshape] {P}; \draw[x=1pt,y=1pt] (0.3,0) -- (6,7); \draw[x=1pt,y=1pt] (3.1,3.5) -- (6.3,3.5); \draw[x=1pt,y=1pt] (0,0.25) -- (1,0.25); \end{tikzpicture} The result (on Overleaf): The AP merged letter, possibly useful to represent pressure in physics when P is already used for power. We see, when attaching the half-A with the P, the font does not match, and the "serif" that I attached does not match the font. How do I add a serif to the end of the diagonal line on the left half of the character that makes the attachment look like a part of the character? Preferably, I'd like a custom line style to lessen the amount of commands I have to do for each half-letter or a specific command to create a serif to be in line with the math font? Or, in this case, is it easier to just create a font? (I'm doing this for all uppercase Latin and lowercase Greek letters for completeness, so that could become quite tedious). I may also have to consider variable line thickness on the left half of the letters too, as seen on the right-side P. In summary, here are the criteria I'm considering in this project: The general shape of a serif when attached to a line at any angle (strait P versus a diagonal V). The variation of width in some lines, such as the curves on B, D and P. Intersections of lines. Advantages and disadvantages of creating a custom font (.sty), creating a serif shape in Tikz, or creating a custom line style for Tikz. This helps decide what the best option is for this project. The application I'm hoping this is useful for is to allow more characters in formulas for math, physics, and other sciences whose design could hint at what the characters mean. For example, in physics, consider the notation for volume and voltage (both are represented by V). If both volume and voltage are in one calculation, what other symbols can we use to represent either one in order to avoid confusion that still show what those symbols represent? In this case, voltage can be VT, and volume can be VU. (The choice is up to the writer, this is just an example). I plan to write a paper over this topic once I get the attachments created. While this is meant for use in physics, I see this having applications in other areas of science and mathematics as well. Thus, which option would be the best for this project, and how do I get started with it? The TIKZ site is helpful, but I did not find anything that looked immediately useful specifically for creation of Serif fonts. Any help would be appreciated!

I am using the box plot prepared method from here: Read boxplot prepared values from a table. My problem is the following: I have multiple rows in that csv and I want a box plot for each of these rows. How can I loop over all rows and create those? Added bonus: Some of my table columns are shorter than others, some have only enough data for 2 box plots, some have enough data for 10 box plots. % 1: extra for box plot, % 2: Identifier % 3: table, % 4: row \newcommandx{\TimeBoxPlot}[4][1={}]{ \addplot+[#2, #1, fill, boxplot prepared from table={ table=#3, row=#4, lower whisker= #2-time-min, lower quartile= #2-time-1, median= #2-time-med, upper quartile= #2-time-q3, upper whisker= #2-time-max, sample size = #2-sample-size, draw position = edge_count, }, boxplot prepared, ] coordinates {}; } % draw % Identifier % Table \newcommandx{\PlotPoint}[3][1={}]{ \pgfplotstablegetrowsof{#3} \pgfmathtruncatemacro{\numrows}{\pgfplotsretval-1} \pgfplotsinvokeforeach{0,...,\numrows}{ \TimeBoxPlot[#1]{#2}{#3}{##1} } } The identifier Mentioned is just a string-prefix for the columns in question and also a style I defined, so they are colored and drawn correctly. Though every Identifier has unbounded coords=discard set thats about the similarities. The implementation of \PlotPoint does not work. It is the macro that should go through all the lines (at least those with values).

I am plotting a family of parabolas in TikZ, and there is a stray parabola.

There is no \tikz command in my code. And I can't seem to find any stray semi-colons in the TikZ code either.

But when I set a minimum width for the box it appears in the center instead: This feels like a bug in tikz. In Left alignment in TikZ, people suggested setting text width or wrapping the content in a parbox. However, these require knowing the width of the text beforehand, otherwise one gets overfull/underfull box warnings, so I do not consider them real solutions. I would expect the text width to be chosen automatically.

I apologized if this is a duplicate. What is the best way to draw such figures with tikz (or other packages)? For the time being just the potato like figure. I do not care for the vectors and the infinitesimal mass element. I do not want someone to do the work for me. Just some advice or suggestions.

I would like node B to have exactly the same width as node A, without explicitly specifying a fixed dimension, with the following constraints: The two nodes are not adjacent in the source code. I do not want to hard-code a width (e.g., minimum width=3cm). Node A will always be at least as wide as node B. I would prefer a solution that does not rely on manually computing dimensions via \path let unless necessary. Here is a minimal example illustrating what I currently have: \documentclass{article} \usepackage{tikz} \usetikzlibrary{calc} \begin{document} \begin{tikzpicture} \node [draw] (A) {Some text}; \path let \p1 = (A.south west), \p2 = (A.north east) in node [draw, minimum width=\x2-\x1-\pgflinewidth, minimum height=\y2-\y1-\pgflinewidth, below right] at ([yshift={\pgflinewidth}]A.south west) {more}; \end{tikzpicture} \end{document}

I have an annual scavenger hunt at Thanksgiving in which the TikZlings and TikZ ducks (and related fauna) guide my nieces and nephew through the course. Given that it is Thanksgiving, I wanted to include a turkey munching on pie and sipping wine, but the closest I can come is \documentclass{article} \usepackage{tikzlings} \begin{document} \begin{tikzpicture} \chicken[cake=orange!50!brown,wine] \end{tikzpicture} \end{document} and that just doesn't have the same ring to it. I found a good wild turkey drawn in MetaPost (Draw a turkey, a pumpkin pie, or any other object traditionally associated with Thanksgiving), but since the holiday is only two days away, I thought I'd see whether anyone was interested in making a picture of Meleagris gallopavo.

I need help putting the page number at the top left of the page and the chapter name at the top right of the page with a long line under them

I want to define a gate in quantikz with my own shape. Let's say I want a triangular gate or $\odot$ (instead of the usual CNOT or the square with letter). How can this be achieved? I looked at the examples in the documentation but I did not find anything similar. For example, imagine adding a gate that looks like an inverter:

I'm trying to make a typical composing-function diagram and I've saw a few posts, but I cannot make it yet as I'd like. In this picture I show what I attempt to make But the most I got is As you can see, I used empty nodes for the broken line, but not exactly worthy. I leave my code here so you can help me with its edition. I must confess I'm basic user in Latex and 100% newbie in Tikz, so any guide you use is welcome. \documentclass{article} \usepackage{amsmath} \usepackage{tikz} \begin{document} \begin{tikzpicture}[node distance=2cm, auto] \node(1) {$C$}; \node(2) [right of=1] {$C_{0}$}; \node(3) [right of=2] {$P_{0}$}; \node(4) [right of=3] {$P$}; \node(5) [right of=4] {$f^{*}(P)$}; \node(11) [below of=1] {}; \node(15) [below of=5] {}; \draw[->](1) to node {$\tau_{c}^{-1}$}(2); \draw[->](2) to node {$l^{-1}$}(3); \draw[->](3) to node {$\tau_{-1}$}(4); \draw[->](4) to node {$f^{*}$}(5); \draw[-](1) to node {}(11); \draw[->](15) to node {}(5); \draw[-](11) to node {$f = \tau_{c}^{-1} \circ l^{-1} \circ \tau_{-1} \circ f^{*}$}(15); \end{tikzpicture} \end{document} Thanks

I have 4 circle nodes with different sizes. Is there a simple way (TikZ, Asymptote,...) to connected them with circular arrow arcs? \documentclass[border=5mm,tikz]{standalone} \begin{document} \begin{tikzpicture}[every node/.style={circle,draw,fill=white}] \def\r{3} \draw[red] (0,0) circle (\r); % 4 nodes with different sizes \path (180:\r) node (Sp) {Spring} (90:\r) node (Su) {Summer} (0:\r) node (Au) {Autumn} (-90:\r) node (Wi) {Winter}; % How to make arrow arcs cicular? (the red one with arrow tips) \begin{scope}[-stealth,bend left] \draw (Sp) to (Su); \draw (Su) to (Au); \draw (Au) to (Wi); \draw (Wi) to (Sp); \end{scope} \end{tikzpicture} \end{document}

Why is the left arrowhead wrong, and how can I fix it? \documentclass[border=5pt]{standalone} \usepackage{tikz} \begin{document} \begin{tikzpicture}[auto] \draw[<->] (0,0) edge node {$a$} (1,0); \end{tikzpicture} \end{document} It works fine if there is no edge node: ... \draw[<->] (0,0) -- (1,0); ...

I'm a beginner with LaTeX and i have insert graph, with a csv file and pfgplots But how can i have the title of the graph in the list of figures. Thank you \begin{center} \begin{tikzpicture} \begin{axis}[% title={$U=E-R\cdot I$ représentation graphique}, no markers, xmin=0, xmax=10, ymin=12, ymax=14, ] \draw[<->,thin] (axis cs:9, 12.5625) -- (axis cs:9, 13); \draw[<->,thin] (axis cs:0, 13.125) -- (axis cs:9, 13.125); \node at (axis cs:9.5,12.784){$\Delta U$}; \node [above] at (axis cs:4.5,13.125){$\Delta I$}; \draw [-,semithick,red] (axis cs:0, 13) -- (axis cs:10, 13); \draw [<-,semithick] (axis cs: 4,12.8) -- (axis cs:4,12.75); \draw [->,semithick] (axis cs: 4,12.75) -- (axis cs:5,12.75); \node [below] at (axis cs:4.5,12.75){$\dfrac{dU(I)}{dI}=-R$}; \addplot table [x=I, y=U, col sep=comma] {test.csv}; \end{axis} \end{tikzpicture} \end{center}

Given the following code: \documentclass{standalone} \usepackage{tikz} \usetikzlibrary{positioning} \tikzstyle{block} = [draw, rectangle, minimum height=3.5em, minimum width=4.5em] \begin{document} \begin{tikzpicture} \node [block,align=center](a) {A}; \node [block,align=center,right=1cm of a](b) {B}; \node [block,align=center,below=1cm of a](c) {C}; \end{tikzpicture} \end{document} I would like that the C-Block, which is below the A- and B-Block takes automatically the width that the A and B Block span. I would like it to look something like this: How can I achieve this without manually setting the width of the C-Block?

I've found this code from How to cross a row in matrix with a line? \documentclass{article} \usepackage{tikz} \newcommand{\pmark}[1]{\begin{tikzpicture}[overlay,remember picture]\node(#1)at (-1em,.7ex){};\end{tikzpicture}} \newcommand{\smark}[1]{\begin{tikzpicture}[overlay,remember picture]\draw(#1)--(0,.7ex);\end{tikzpicture}} \begin{document} $$\begin{array}{cccc|c} a&b&bc&d&f\\\hline 0\pmark{a}&0&1&1&1\smark{a}\\ 0&0&0&1&0\\ 0&0&1&1&1\\ \end{array}$$ \end{document} It works like a charm for rows but the lines are quite skewed. Can someone see how to fix this to work for both rows and columns?

I understand that this post may cause some down votes because it seems a bit off-topic, but having seen the discussions on Christmas Tree with LaTeX I am still willing to try. How do you draw a red cute love heart using LaTeX?

How can I get a linebreak inside a matrix node? The following gives the error: Package tikz Error: Giving up on this path. Did you forget a semicolon?. unless I remove the linebreak. \documentclass{standalone} \usepackage{tikz} \usetikzlibrary{chains} \usetikzlibrary{matrix} \begin{document} \begin{tikzpicture} \matrix (m) [ matrix of nodes ] { {some text} & {this node \\ does not work} \\ {other text} & {more text} \\ }; \end{tikzpicture} \end{document}

I feel intimidated in learning TikZ. I was wondering if there are some nice materials (or just your replies) at different level: for providing big picture, which is important to beginners to not lose direction during learning. for comprehensive reference. Examples are important, but only examples are not always clear for understanding the big picture and organization.
