TikZ

I'm trying to create a graph paper document and have the text align to the grid (Not just superimposed on it). The text should at least align with baseline of the grid, but better yet, each character should be placed inside the grid like if you were handwriting on graph paper.

I have the following code, with line cap=round: \documentclass[margin=5pt]{standalone} \usepackage{circuitikz} \begin{document} \begin{circuitikz}[ european, line cap=round, ] \draw (0,0) to [rmeter] (0,2) -- (1,2) |- (0,0); \end{circuitikz} \end{document} It shown as normal in "Adobe Acrobat Reader": However, with PDF-XChange Editor, the strange dot appeared by line cap=round... Edited: Mine PDF-XChange Editor's version is v10.5.2.

In Tikz diagrams, one of the best ways to make controlled curved lines (such as pointing arrows in a flow chart) is using \draw with control points. For example, \documentclass{article} \usepackage{graphicx} \usepackage{tikz} \usetikzlibrary{decorations.pathmorphing} \usetikzlibrary{shapes.arrows, arrows.meta} \begin{document} \begin{figure} \begin{tikzpicture} \draw[thick,->,>=Stealth, show controls] (0,0) .. controls (0.5,3) and (4.5,0).. (5,5); \end{tikzpicture} \end{figure} \end{document} However, I feel like it ends up being a sort of guessing game when trying to determine where to actually place the control points, because I have a hard time visualizing where the points are and how their position affects the curved line. I understand how the points effect the line very intuitively, but moving said points to the desired location is easier when you can see the points as well. Is there any simple way to "toggle" on a display of the control points, so that you can see them while editing the diagram, and then hide them when you've got the line that you want?

Is there an easy way to get all in the same line width thickness? I tried to calc some things but I do not think this was correct: \pgfmathsetlengthmacro\lw{2.1pt}% wanted linewidth (circuitikz default 0.8pt) \pgfmathsetlengthmacro\lwc{0.8pt}% circuitikz default linewidth 0.8pt % ----> could this be read out somehow? \pgfmathsetmacro\th{\lwc/\lw}% needed bipoles/thickness % ---> do not think, this is correct \documentclass[margin=5pt]{standalone} \usepackage{tikz} \usepackage[]{circuitikz} %\ctikzset{bipoles/thickness=3} \pgfmathsetlengthmacro\lw{2.1pt}% wanted linewidth (circuitikz default 0.8pt) \pgfmathsetlengthmacro\lwc{0.8pt}% circuitikz default linewidth 0.8pt % ----> could this be read out somehow? \pgfmathsetmacro\th{\lwc/\lw}% needed bipoles/thickness % ---> do not think, this is correct \begin{document} \begin{tikzpicture}[european, line width=\lw, circuitikz/bipoles/thickness=\th,% default 2 %circuitikz/sources/symbol/thickness=\th,% default 1 ] \draw (0,3) to [sinusoidal voltage source, v=$u(t)$, ] (0,0); \draw (0,3) to[C=$C$] (4,3) to[resistor={$R$}] (4,0) to[battery1, invert] (0,0); \node[align=left, anchor=north west, fill=yellow!25] at (0,-1) { \textbf{Values}: \\ lw: \lw \\ th: \th \\ bipoles/thickness: \ctikzvalof{bipoles/thickness} \\ circuitikz/sources/symbol/thickness: \ctikzvalof{circuitikz/sources/symbol/thickness} ? \\ ...... }; \end{tikzpicture} \end{document}

I am designing a complex lesson plan layout using tcolorbox. The design features specific vertical strips (margins) defined in the box's overlay. I use custom commands (\mrhala, \Time, \rems) based on TikZ to place content into these strips using absolute positioning relative to the page or box width. The Problem: The code works perfectly and aligns correctly when compiled with PDFLaTeX (LTR). However, my final document requires Arabic, so I must use XeLaTeX with polyglossia. When I switch to XeLaTeX, the horizontal positioning of these marginal notes breaks. They shift incorrectly or overlap, especially when used inside nested boxes. It seems that the coordinate calculations (e.g., \dimexpr, xshift) or the origin point (0,0) behave differently in the RTL context of XeLaTeX. Screenshots: Correct Output (PDFLaTeX): The marginal notes align perfectly with their columns. Incorrect Output (XeLaTeX with Polyglossia): The notes are shifted and misaligned.

Scenario Consider the following: One needs to draw from a point on a curve following its tangent direction. TikZ provides for this scenario the ([turn]<ANGLE>:<DISTANCE>) syntax. As one continues the image, it becomes too big for the page layout. In order to prevent having to recreate the complete image with a smaller size, one tries to use the scale parameter (globally on the tikzpicture or via scope does not make a difference for this scenario). MWE \documentclass{standalone} \usepackage{tikz} \begin{document} \begin{tikzpicture} % DESCRIPTION: Plain, no modification % STATUS: WORKING \draw[black] (0,0) arc(0:90:-1.5 and 1.5) arc(90:135:-2.0 and 2.0) --([turn]0:0.5) node[below]{plain} ; % DESCRIPTION: Scale % STATUS: FAIL \begin{scope}[scale=0.5] \draw[red] (0,0) arc(0:90:-1.5 and 1.5) arc(90:135:-2.0 and 2.0) --([turn]0:0.5) node[below]{scale} ; \end{scope} % DESCRIPTION: Shift % STATUS: FAIL \begin{scope}[xshift=5cm] \draw[red] (0,0) arc(0:90:-1.5 and 1.5) arc(90:135:-2.0 and 2.0) --([turn]0:0.5) node[below]{xshift} ; \end{scope} \end{tikzpicture} \end{document} Result As soon as transformation are applied, the result of the ([turn]<ANGLE>:<DISTANCE>) specification is wrong. Research so far It was tried to encapsulate the \draw command into a TikZ pic, hoping that this might act as a wrapper, but the result was identical. The corresponding section 13.4.2: Rotational Relative Coordinates of the TikZ manual specifies: The effect of this key is to locally shift the coordinate system so that the last point reached is at the origin and the coordinate system is “turned” so that the (x)-axis points in the direction of a tangent entering the last point. From that, I would assume that certain global transforms cannot/will not be taken into account properly. Question Is it possible to use the ([turn]<ANGLE>:<DISTANCE>) syntax under (global) transformations? If not, is there another option to achieve the same functionality or an easy way to implement it?

I am designing a complex document layout using tcolorbox. The main container (BoxDars) has specific vertical strips (margins) defined in its overlay. I have created custom commands (\mrhala, \Time, \rems) to place content into these specific strips using TikZ overlays. The Problem: These commands work fine in the main box. However, when I use them inside nested boxes (e.g., inside box2 or box3), the horizontal positioning shifts incorrectly. I tried to compensate for the nesting depth using \value{tcblayer}, but the alignment is still inconsistent. Goal: I want the content of \mrhala, \Time, and \rems to strictly stick to their respective vertical columns defined in the parent BoxDars, regardless of how deep the nesting is.

I am designing a lesson plan layout using tcolorbox and TikZ in XeLaTeX with polyglossia (Arabic). The layout (BoxDars) has a specific right margin reserved for "Stages" (المراحل). I defined a command \mrhala to place vertical text in that specific strip. The Problem: The \mrhala command relies on current page coordinates and manual shifts, which makes it unstable. It does not land exactly in the reserved vertical strip defined in the BoxDars overlay, especially when I change nesting or margins. Goal: I want the vertical text generated by \mrhala to be absolutely positioned centered within the right margin strip (the white space between the red line and the right edge of the box), regardless of where the box is on the page.

My idea would be to build a list containing the names of \coordielem with etoolbox, convert it to a csvlist with etextools, then iterate over it with TikZ's \foreach method. But, clearly, I am missing something. Any idea?

I want to create a breadboard whose x-slot spacing matches the pin spacing of a muxdemux (this was done here); and whose y-slot spacing matches the pin spacing of an op amp. An image for clarification: I can approximate the y-direction by trial and error, using \pgfmathsetlengthmacro\OApin{% 'op amp' pin width \bl*\ctikzvalof{tripoles/op amp/width}*0.3*0.5} But I would like to do this accurately and precisely. In short: I need height, width, and pin spacing of an op amp from the package-keys. (Unfortunately, these keys are usually well hidden and not very self-explanatory.) \documentclass[margin=5pt, multi=circuitikz]{standalone} \usepackage{circuitikz} \def\ShowBreadBoard{1} % Breadboard 1/2 ====================== % Default of bipoles/length ================= \pgfmathsetlengthmacro\bl{\UseName{pgf@circ@Rlen}}% default 1.4cm %%%%%%%%%% Problems here %%%%%%%%%%% % Breadboard y - measures of 'op amp' ================= \pgfmathsetlengthmacro\OApin{% 'op amp' pin width \bl*\ctikzvalof{tripoles/op amp/width}*0.3*0.5} \pgfmathsetlengthmacro\OAh{% 'op amp' height \bl*\ctikzvalof{tripoles/op amp/height}} \pgfmathsetlengthmacro\OAw{% 'op amp' width \bl*\ctikzvalof{tripoles/op amp/height}*5/6+0*\pgflinewidth/cos(45)} %%%%%%%%%%%%%%%%%%%%%%%%% % Breadboard x - measures of 'MuxDemux' ================= \pgfmathsetlengthmacro{\basemuxlen}{\bl *\ctikzvalof{multipoles/muxdemux/base len} *\ctikzvalof{muxdemuxes/scale}} \pgfmathsetlengthmacro{\MUXw}{\basemuxlen*6}%w=6, muxdemux-width %\pgfmathsetlengthmacro{\MUXh}{\basemuxlen*4}%Lh=4, muxdemux-height \pgfmathsetlengthmacro{\MUXp}{\MUXw/3}% bottom pin distance of muxdemux \begin{document} \begin{circuitikz}[] % Breadboard 2/2 ================ \begin{scope}[font=\footnotesize\ttfamily] \pgfmathsetlengthmacro\u{\MUXp/4}% x-unit-length \pgfmathsetlengthmacro\v{\OAh/4}% y-unit-length \def\X{x} \def\Y{y}% letters for coordinates \foreach \x in {0,...,26}{%% \foreach \y in {0,...,6}{% \ifnum\ShowBreadBoard=1 %%%%%%%%% \pgfmathtruncatemacro\Xt{mod(\x,2)==0 ? 1 : 0}% show x-coordinate test \pgfmathtruncatemacro\Yt{mod(\y,2)==0 ? 1 : 0}% show y-coordinate test \fill[gray] (\u*\x,-\y*\v) circle[radius=0.65pt] coordinate[label=](\X\x\Y\y); \ifnum\y=0 \node[above, red] at (\X\x\Y\y) {\ifnum\Xt=1 \x\fi};\fi \ifnum\x=0 \node[left, red] at (\X\x\Y\y) {\ifnum\Yt=1 \y\fi};\fi \draw[red, shorten <=2pt] (x0y0) -- +(135:0.75) node[midway, above]{x} node[near end, below]{y}; \else% \coordinate[](\X\x\Y\y) at (\u*\x,-\y*\v); \fi%%%%%%%%%%%%%% }}% %% %\node{\OAw, \OAh};% test %\draw (x0y0) circle(1mm); % test \end{scope}% ===================== \node[op amp](opamp) at (x8y3) {}; \draw (x15y3) to[L, color=pink] (x22y3); \end{circuitikz} \end{document}

What I want to achieved is as below: I have the following code: \documentclass[border=5pt]{standalone} \usepackage{circuitikz} \begin{document} \begin{circuitikz}[european] \draw(0,0) to [rmeter,t=A] (0,2) to [R,l_=$R$](3,2) to [pR,l_=$R'$,n=pr] (4.1,2); \draw(0,0) to [normal open switch,l_=$S$] (6,0) |-(pr.wiper); \end{circuitikz} \end{document} it gives the similar result: However, the righthand of sliding rheostat's length is control in manual, but guess the coordinate (4.1,2), which is not elegant. I have consulted the manual, but found no similar components. Is that better method to achieve the desird result?

Due to a chat-talk with @Rmano, I asked myself wether there is a methode to set the rounded corners of a oscopeshape to 0pt or to a very small value. The rounded corners can become weird, if I set a small scale: \documentclass[margin=10pt]{standalone} \usepackage{circuitikz} \begin{document} \begin{circuitikz}[font=\footnotesize] \node[oscopeshape] (A){scale=1}; \node[oscopeshape, right of=A, scale=0.5](B) {scale=0.5}; \node[oscopeshape, right of=B, scale=0.35] {scale=0.35}; \end{circuitikz} \end{document}

How do I get these two lengths? By the way: a) I don't need the height right now, but I assume the extraction method would be the same; so it wouldn't hurt to have it... b) I know how to do it with the calc library. However, it would be better if I could get the dimensions directly from the circuitikz package, without having to measure them after drawing. \documentclass[margin=15pt]{standalone} \usepackage{circuitikz} \begin{document} \tikzset{ circuitikz/muxdemux/outer label font={\tiny\ttfamily\color{blue}}, mychip/.style={muxdemux,% ===================== muxdemux def={ Lh=4, Rh=4, w=6,% sizes NR=0, NL=5, NB=3, NT=3,}, muxdemux label={ %T1=T1, T2=T2, T3=T3, B1=B1, B2=B2, B3=B3, BR1=br1, BL1=bl1, BR2=br2, BL2=bl2, BR3=br3, BL3=bl3,% %TR1=tr1, TL1=tl1, TR2=tr2, TL2=tl2, TR3=tr3, TL3=tl3,% LU1=lu1, LD1=ld1, LU2=lu2, LD2=ld2, LU3=lu3, LD3=ld3, LU4=lu4, LD4=ld4, LU5=lu5, LD5=ld5, }, draw only top pins={}, append after command={ \pgfextra \def\fg{\tikzlastnode} % Contacts annotations ============== \foreach \x in {1,2,3}{%% \node[bnc, anchor=zero, rotate=-90](Contact\x) at (\fg.blpin 5 -| \fg.btpin \x) {}; \draw[] (Contact\x) -- (\fg.bbpin \x); }%% \endpgfextra }, },% ===================== } \begin{circuitikz}[>=latex] \node[mychip](FG){chip}; \draw[purple, <->] (FG.north west) -- (FG.north east) node[midway, fill=white, inner sep=0pt]{w=? pt}; \draw[orange, <->] (FG.bpin 1) -- (FG.bpin 2) node[midway, below]{p=? pt}; \end{circuitikz} \end{document}

Why? Any idea? These pgfkeys are very nice, but, for me, very challenging to handle, and the manual doesn't help me much.

I wanted to set the coordinate that it's height is one third of a box that consists of 1 line, but tikz don't understand.

I'm trying to create a worksheet-like template, and I run into some issues with the grid. Really big space pops up, and I don't know how to get rid of it. I'm using tikz.

From time to time I search if there is a practical/eficient way to create maps, similar to the next ones, even with a terrain texture or even contour level. Are there any tikz library appropiate for this purpose? Images from https://rpgmapsforge.com/

What I am trying to achieve is to set a pgfkey (south of, for example), which would be a placeholder for the native option below=of <node> and to pass it to a custom command.

If I set some coordinates inside a node named (Box) (with path picture), say (A),(B),(C). How can I get the (from other codes known) (Box.A) syntax? \documentclass[margin=5pt]{standalone} \usepackage{tikz} \begin{document} \begin{tikzpicture}[ test/.style={minimum width=3cm, minimum height=2cm, fill=lightgray, draw, path picture={%% \draw[purple] (path picture bounding box.200) -- (path picture bounding box.-20) coordinate[pos=0.2, label=center:A](A) coordinate[pos=0.5, label=center:B](B) coordinate[pos=0.8, label=center:C](C); },%% }, ] \node[test](Box){}; \draw[red ,<-] (A) -- +(-135:1) node[right]{$\to$A}; % Needed: (Box.A), (Box.B), ... % \draw[red ,<-] (Box.A) -- +(-135:1) node[right]{$\to$A}; % \draw[red ,<-] (Box.B) -- +(-45:1) node[right]{$\to$B}; \end{tikzpicture} \end{document}

I want to create a 6x5 dotted grid over an area with clearly defined width and height (\w and \h). Can I configure the grid to only display points at the intersections of the horizontal and vertical lines? I only get that with dash pattern=on 0pt off \w/6, for the x-positions. What do I have to do? By the way: I'm wondering, as a task out of pure interest, how one can adjust the grid. It's clear how to manually create the image using foreach-loops. \documentclass[margin=5pt]{standalone} \usepackage{tikz} \pgfmathsetlengthmacro\w{2cm} \pgfmathsetlengthmacro\h{3.2cm} \begin{document} \begin{tikzpicture}[] \draw[] (0,0) rectangle (\w,\h) node[anchor=south east, align=center]{ Dots only at \\ all intersections \\ of the horizontals \\ and the verticals}; \draw[orange, xstep=\w/6, ystep=\h/5] (0,0) grid (\w,\h); \end{tikzpicture} \begin{tikzpicture}[] \draw[] (0,0) rectangle (\w,\h); \draw[orange, xstep=\w/6, ystep=0*\h/5, % Dotted Style: line width=1.0pt, dash pattern=on 0pt off \w/6, line cap=round, ] (0,0) grid (\w,\h); \end{tikzpicture} \end{document}

I want to draw something like: \documentclass[tikz,border=5pt]{standalone} \begin{document} \begin{tikzpicture}[radius=4] % \draw[help lines] (-4,-4) grid (4,4); \begin{scope} \draw[clip] ({2*sqrt(2)},{-2*sqrt(2)}) arc [start angle=315,delta angle=90] arc [start angle=-45,delta angle=-90] arc [start angle=135,delta angle=90] arc [start angle=135,delta angle=-90] ; \fill[gray] ({4*sin(22.5)},-4) rectangle (4,4); \end{scope} \draw[dashed] ({2*sqrt(2)},{2*sqrt(2)}) arc [start angle=45,delta angle=90] ({2*sqrt(2)},{-2*sqrt(2)}) arc [start angle=-45,delta angle=-90] (0,{4-2*(4-2*sqrt(2))}) -- (0,{-(4-2*(4-2*sqrt(2)))}) ; \draw[thick] (4,0) -- (-4,0); \end{tikzpicture} \end{document} However, there are too many arcs and manually calculated coordinate and distance, I want to make good use of \clip, but it look a little bit hard than my expected, the border, is hard to control... Noted that the two code, I give, the parameter is not the same, that is not important. I want to focused on how to use clip magic to do so: what I have tried with \clip, the border is clipped in wrong... \documentclass[tikz,border=5pt]{standalone} \begin{document} \begin{tikzpicture}[radius=4] \clip circle[]; \draw[help lines] (-4,-4) grid (4,4); \draw[dashed,fill=gray] circle[]; \begin{scope} \clip (-4,-3) rectangle (4,3); \fill[white] (-4,-4) rectangle (1.5,4); \end{scope} \draw[fill=white] (0,6) circle[] (0,-6) circle[]; \end{tikzpicture} \end{document} If possible, I want to know the thought of how to design such proper drawing scheme.

For the graphics I use on my physics exercise sheets made with TikZ I often use the same objects (hooks, masses, carts, pulleys, force gauges,...). So instead of copy-pasting and modifying the code of these objects I think it makes sense to make them into a ready to use object. There are three ways I know of to make that happen: TeX macros, pics and shapes. There are some features I wish the implementation of these objects to have and need some advice on how to implement it in order to have those features: An object should have multiple anchors so I can easily use certain points for further construction and choose which anchor to use for the placement (so there is no need to calculate that stuff manually). The hook for example could be placed at it's base or the actual hook and either one should be available afterwards for further placement of objects or paths. A default style should be set, i.e. the fill color or shading of the mass body, that can be overwritten. If placed inside a scope that changes shift, rotation, scale, line width,... these changes should automatically also apply to the object as a whole. I want to be able to construct new objects from already existing objects, i.e. I want to be able to use the hook as part of the mass, force gauge and cart. Right now I'm leaning towards defining new shapes, even tho I haven't used low level pgf before. As far as I can see 1 and 3 are no problem with shapes. I feel like 2 could also be achieved (any hints are appreciated - maybe defining a new style that uses that shape?). I however have no Idea if or how to make 4 work in defining a new shape. Pics on the other hand would make 2 and 4 easy as far as I can imagine. But they don't respond to the settings of a scope (3). Also anchors (1) are not natively supported but using tikzmark one answer to this question Anchoring TiKZ pics suggests this could be achieved as well (although I imagine it to be not quite as powerful as a new shape and takes two compilation runs if I understood correctly). Any thoughts, hints or pieces of advice are very welcome. I hope I described the setting clear enough. Edit The following Example is not meant to be beautiful but hopefully helps to illustrate the issue: \documentclass[tikz]{standalone} \usetikzlibrary{calc} \usetikzlibrary{tikzmark} \begin{document} \tikzset{ hook/.pic={ \draw[double=gray!80, double distance=1.4pt] (0,0) .. controls (0,-1.5) and (0,{1/sin(45)-2.5}) .. ($(45:1)+(0,-2.5)$) arc(405:140:1); \node[inner sep=2mm] (-hole) at (0,-2.5) {}; } } \tikzset{ cart/.pic={ \shadedraw[left color=blue, right color=blue!50] (-3,0) rectangle (3,2); \shadedraw[left color=black, right color=gray] (2,-.8) circle (.8); \shadedraw[left color=black, right color=gray] (-2,-.8) circle (.8); \pic[transform shape,rotate=90,scale=.5] (h) at (3,1) {hook}; \coordinate (-front-wheel) at (2,-1.6); \coordinate (-back-wheel) at (-2,-1.6); \node[inner sep=2mm] (-hook) at (h-hole) {}; } } \begin{tikzpicture} \draw (0,0) -- (8,0) -- (8,2); \pic[pic anchor=(-back-wheel),scale=.5] (cart) at (.5,0) {cart}; \pic[rotate=270,xscale=-1,scale=.25] (hook) at (8,0|-cart-hook) {hook}; \draw[ultra thick, line cap=round] (cart-hook) -- (hook-hole); \end{tikzpicture} \end{document} So using a pic with tikzmark (and transform shape as I've discovered) seems to check all the requirements. Can this also be achieved with a custom shape? As in this solution I dislike a few things: tikzmark needs two compilation runs no border anchors can be defined (at least I don't know how) It seems to me all anchors are defined every time a pic is inserted and not calculated when needed as with shapes. I'm not sure about the impacts on compilation time.

I have a tikz picture that I apply scale=0.9 to that \draws a rectangle, like this: \documentclass{standalone} \usepackage{tikz} \begin{document} \begin{tikzpicture}[scale=0.9] \draw[draw=red, fill=red, fill opacity=0.3, thick] (0.24999999999999997, 5.8) -| (0.44999999999999996, 6.2) -| cycle; \end{tikzpicture} \end{document} This results in one corner not having the correct line join: If I would remove the scale argument, the line joint would be correct, but the whole picture no longer fits on my page. I also would like to avoid having to manually multiply all coordinates with 0.9. As a workaround, I could draw a second rectangle over it, with the "missing" corner in a different location. Is there a better solution?

Here the curve is drawn with a single color (red) It's easy to get the solution curve. The below figure is drawn in this app for y'=x^2+y^2-1, y(0)=1/2. As you can notice the color of the curve is varying from red (x<-1) to purple (-1<x<1) then to blue (x>1). It is not color set of the rainbow, so it is not synchronious to the Rainbow colormap. My question: How to add a given colormap (such as Rainbow) to a solution curve of a vector field? I guess this is a kind of popular, but can not find a way with Asymptote. I expect not only Asymptote code but also any others as TikZ, MetaPost, lua, etc. The code should be apply for any colormaps Please use my code here as MWE.

I am to convert an SVG image to TikZ code. I have never done that before thus I have a few questions. First of all do I need Inkscape or any other program like this? Maybe there is a method using just Python? Have you ever done that before? Are there any typical errors or problems?
