pgfplots

I am trying to implement a dynamic labeling system for multiple curves within a pgfplots axis environment. The goal is to have curve labels that are both tangential (sloped) to their respective paths and capable of avoiding collisions by utilizing a 1D force-based relaxation mechanism to repel each other along the curves' domains. My Understanding of pgfplots Internals From what I understand of pgfplots internals, and please correct me if my assumption is flawed, the package operates on a deferred drawing (or accumulation) model, conceptually quite similar to how matplotlib handles figures in Python. It seems to split its workflow into distinct steps: A Survey Phase where it reads \addplot data, accumulates coordinates in memory, and computes the global axis limits. A Visualization Phase triggered at \end{axis} where it maps data coordinates to physical dimensions and emits the actual TikZ paths and nodes. Based on this understanding, it feels like the ideal place to inject a label-relaxation algorithm would be right between these two phases (perhaps using hooks like before end axis), after the data is parsed but before the final typesetting occurs. The Technical Bottleneck: The Node Bounding Box Dilemma The core difficulty I am facing is a classic "chicken-and-egg" problem: To know the dimensions (width, height, depth) of a label's bounding box for collision detection, TeX must first typeset the text into a box. However, we cannot definitively position or rotate that node along the path until the force-based algorithm has computed the final, relaxed $t$ parameters for all curves. If a LuaLaTeX-based approach is required to handle the physics/loop, I am completely open to it. But I am unsure how to elegantly pass TeX box dimensions into Lua, or how to query the generated curve paths before the rendering phase. Minimal Working Example (Current State) Here is a basic MWE where the labels are sloped but completely overlap: \documentclass[border=5mm]{standalone} \usepackage{pgfplots} \pgfplotsset{compat=1.18} \begin{document} \begin{tikzpicture} \begin{axis}[ domain=0:3.5, restrict y to domain = 0:10, samples=100, axis lines=left ] % Curve 1 \addplot[blue, thick] {x^2} node[pos = 0.2, sloped] {Function $f(x)$}; % Curve 2 \addplot[red, thick] {1/x} node[pos = 0.8, sloped] {Function $g(x)$}; \end{axis} \end{tikzpicture} \end{document} Tentative Logic / Pseudo-code (Force-Based Relaxation) Ideally, the macro or Lua script would perform a spring-embedder / force-directed approach constrained to 1D path coordinates: # Pre-computation phase for each label L_i: Typeset L_i into a temporary TeX box to get its dimensions (W_i, H_i) # Force-directed loop while system_not_in_equilibrium and max_iterations_not_reached: Initialize forces F_i = 0 for all labels for each curve i with label L_i: 1. Get baseline position P_i = curve_i(t_i) 2. Compute tangent angle theta_i at t_i 3. Construct Label Bounding Box B_i (using W_i, H_i) at P_i rotated by theta_i for each pair of labels (L_i, L_j): if Intersect(B_i, B_j): # Compute repulsive force based on overlap magnitude force_magnitude = calculate_repulsive_force(B_i, B_j) # Project force along the 1D direction of the respective curves F_i = F_i - force_magnitude F_j = F_j + force_magnitude # Update positions using a small step size (damping) for each label L_i: t_i = t_i + alpha * F_i ConstraintToValidDomain(t_i) Questions & Directions Is my mental model of the pgfplots accumulation process accurate enough to build upon, or am I missing a fundamental constraint of the package architecture? Is there an existing package or experimental snippet that already handles force-based label placement or relaxation algorithms along TikZ paths? If doing this via LuaLaTeX, what is the cleanest way to intercept the path coordinates generated by pgfplots and pass the TeX box dimensions to a Lua-based physics loop? Any pointers, conceptual corrections, or architectural advice would be highly appreciated. Real-World Use Case (Thermodynamic Diagrams) To provide some concrete context on why this automation is so critical for my workflow, here is a screenshot of the type of complex diagram I am currently generating (with luatex, FFI and the CoolProp shared library). It is a pressure-enthalpy (p-h) diagram widely used in refrigeration and chemical engineering, plotted in the (p, log h) plane for a pure substance. As you can see, the visual density is extremely high because it overlays several distinct families of isolines crossing each other: Isotherms (constant temperature) Isentropes (constant entropy) Isochores (constant specific volume) Vapor quality lines / isotitres (constant dryness fraction) Manually hardcoding and fine-tuning the pos parameter for dozens of labels across these intersecting families of curves is completely unmanageable—especially since the curves shift dramatically depending on the thermodynamic properties of the fluid being modeled. Having a generalized, tangential, force-directed algorithm to let these labels dynamically find their equilibrium along their respective paths would be an absolute game-changer for rendering complex engineering charts natively in pgfplots.

In attempting to draw three planes using tikzpicture and addplot3s, I'm encountering the following issue: when adding the a third steep plane, the z axis is rescaled, visually changing the angle between the existing planes. How can I keep the steep plane without causing the z axis to be rescaled?

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 would like to plot the following function in LaTeX using TikZ or pgfplots: \[ y = x^{2/3} + 0.8 \cdot \cos(kx) \cdot \sqrt{3 - x^2} \] The domain is \( - \sqrt{3} \leq x \leq \sqrt{3} \). I need to create a nice graph where: The curve looks smooth I can easily change the value of \( k \) (number of oscillations) The modulated amplitude (the \( \sqrt{3-x^2} \) part) is clearly visible I have tried basic \addplot but I have problems with the fractional power \( x^{2/3} \) and with making the cosine oscillation look good.

The spec: Any number of (arbitrary) color bands that we specify filling text Stroked outline Same positioning as normal text No extra text in the pdf stream (for copy-paste behavior you would expect) Ok and we're back to it! Previous versions have led here. None of the solutions so far have checked every box. We got as far as implementing 1-3. This is why this question is not a duplicate of the linked questions. None of the linked solutions implement 4 which is important to me. They all draw the text multiple times which unfortunately shows up in the pdf stream. I think that it is because for each \node the text is written again, This final version should have completely normal text-selection behavior, i.e, only ONE copy of the text. I have a new macro that attempts to use \accsupp to hide the extra copies of the text, but it does not work when I test it on Sumatra. I think that it does fix it for screen readers though which is why I kept it. It will however work when I try it in random other pdf readers like chrome. What I really want here is something that somehow only writes the text once, while looking exactly as this does, so that it should work in almost all pdf viewers. % !TEX TS-program = lualatex \documentclass{article} \usepackage{tikz} \usetikzlibrary{calc} \usepackage{pgfplots} \usepackage{accsupp} \usepackage{pdfrender} \newcommand{\TextShadeContour}[3]{% \begin{tikzpicture}[baseline] % Define reference node invisibly — needed for clip coordinates \node[anchor=base, inner xsep=0pt, inner ysep=.5pt, outer sep=0pt, opacity=0] (n) at (0,0) {#3}; % Scope contains all the cumulative clips from the loop \BeginAccSupp{method=plain,ActualText={}}% \begin{scope}% \foreach \c in {1,2,...,#1}{% \pgfplotscolormapaccess[1:#1]{\c}{ShadingColor}% \definecolor{colortemp}{rgb}{\pgfmathresult}% \pgfmathparse{1-(\c-1)/#1}% \clip let \p1=(n.south west), \p2=(n.north east), in% (n.south west) rectangle (\x2, \y1+\pgfmathresult*\y2-\pgfmathresult*\y1);% \node[colortemp, anchor=base, inner xsep=0pt, inner ysep=.5pt, outer sep=0pt]% {#3};% }% \end{scope}% \EndAccSupp{}% % Stroke is now outside the scope, so clipping is fully reset \node[anchor=base, inner xsep=0pt, inner ysep=.5pt, outer sep=0pt] at (0,0) {\textpdfrender{ TextRenderingMode=Stroke, LineWidth=0.5pt, StrokeColor=#2, MiterLimit=0.5, LineJoinStyle=Round }{#3}}; \end{tikzpicture}% }% \begin{document} \pgfplotsset{colormap={ShadingColor}{rgb255=(112,128,144) rgb255=(255,159,101)}}\TextShadeContour{3}{black}{13}\\ \end{document} The question is (maybe) how to use pdf literal commands to do it. My own knowledge of pdf internals is non-existent. Or it's about drawing the path of the text from within tikz vs. the actual text. Hopefully we don't have to use ghostscript or anything funky. Ideally this will just work in a way where we define the macro once and then use it. I know a pdf file can contain this. I can prove it with this typst MWE. If you run it and copy paste the whole line, it will do it just as we want (stuff and other stuff): #let multicolor_outline(content, colors) = { let grad = gradient.linear(..colors, angle:270deg) set text(stroke: 0.3pt, fill: grad.sharp(colors.len())) box(content) } #multicolor_outline([stuff], (red, orange, yellow, green, blue, purple)) and #multicolor_outline([other stuff], (purple, blue)) Previous discussion (which does not involve functional copy-pasting): Question 1 Question 2

I'm trying to recreate the look of a 3D coordinate system as used in German schoolbooks. Below, I've included a minimal working example (MWE). The code that handles the grid and tick marks is quite lengthy, and my implementation isn’t very robust when it comes to making changes. Is there a simpler and more reliable way to achieve the desired result using pgfplots, particularly regarding the style and placement of tick marks and the background grid? I considered modifying the tick mark style, but as far as I can tell, there's no built-in option for this. (Avoid multiple tick marks in 3D tikz plot). I looked through the source code of pgfplots for a code piece I could patch, but I wasn't able to understand what's going on. It seems in an earlier version of pgfplots there was a bug that kind of "implemented" the tick mark style I'm looking for: Uniform appearance of tick marks in 3d pgfplot? Fix: https://github.com/pgf-tikz/pgfplots/commit/47a07927c46ecbdcd8a982c90c922bc4925e828b Is there a way to access the tick positions directly directly? Is there an easier option to have the tick marks always have length 0.1 inch regardless what value the ytick distance is? In the target style, the orientation of the axes will always be the same as shown in the example, and the distance between two grid lines should always be 5 mm. I’d like to retain this consistent layout while being able to freely adjust other parameters in the plot. Any other suggestions or improvements are very welcome. \documentclass{standalone} \usepackage{pgfplots} \pgfplotsset{compat=1.18} \newcommand{\unitvectorx}{(\pgfkeysvalueof{/pgfplots/minor x tick num} + 1)*0.5/\pgfkeysvalueof{/pgfplots/xtick distance}} \newcommand{\unitvectory}{(\pgfkeysvalueof{/pgfplots/minor y tick num} + 1)*0.5/\pgfkeysvalueof{/pgfplots/ytick distance}} \newcommand{\unitvectorz}{(\pgfkeysvalueof{/pgfplots/minor z tick num} + 1)*0.5/\pgfkeysvalueof{/pgfplots/ztick distance}} \pgfplotsset{ 3d_style/.style={ axis lines = middle, tick style = transparent, major tick length = 0.1in, minor tick num = 1, xtick distance = 1, ytick distance = 1, ztick distance = 1, xlabel = $x_1$, ylabel = $x_2$, zlabel = $x_3$, x = {(-.5cm*\unitvectorx,-.5cm*\unitvectorx)}, y = {(1cm*\unitvectory,0)}, z = {(0,1cm*\unitvectorz)}, set layers = standard, execute at end axis = {\pgfmathsetmacro{\xenlarge}{(\pgfkeysvalueof{/pgfplots/xmax} - \pgfkeysvalueof{/pgfplots/xmin}) * \pgfkeysvalueof{/pgfplots/enlarge x limits})} \pgfmathsetmacro{\yenlarge}{(\pgfkeysvalueof{/pgfplots/ymax} - \pgfkeysvalueof{/pgfplots/ymin}) * \pgfkeysvalueof{/pgfplots/enlarge y limits})} \pgfmathsetmacro{\zenlarge}{(\pgfkeysvalueof{/pgfplots/zmax} - \pgfkeysvalueof{/pgfplots/zmin}) * \pgfkeysvalueof{/pgfplots/enlarge z limits})} \pgfmathsetmacro{\xmin}{\pgfkeysvalueof{/pgfplots/xmin} - \xenlarge} \pgfmathsetmacro{\ymin}{\pgfkeysvalueof{/pgfplots/ymin} - \yenlarge} \pgfmathsetmacro{\zmin}{\pgfkeysvalueof{/pgfplots/zmin} - \zenlarge} \pgfmathsetmacro{\xmax}{\pgfkeysvalueof{/pgfplots/xmax} + \xenlarge} \pgfmathsetmacro{\ymax}{\pgfkeysvalueof{/pgfplots/ymax} + \yenlarge} \pgfmathsetmacro{\zmax}{\pgfkeysvalueof{/pgfplots/zmax} + \zenlarge} \pgfmathsetmacro{\ygriddist}{\pgfkeysvalueof{/pgfplots/ytick distance} / (\pgfkeysvalueof{/pgfplots/minor y tick num} + 1)} \pgfmathsetmacro{\zgriddist}{\pgfkeysvalueof{/pgfplots/ztick distance} / (\pgfkeysvalueof{/pgfplots/minor z tick num} + 1)} \pgfmathsetmacro{\ygridmin}{ceil(\ymin / \ygriddist) * \ygriddist} \pgfmathsetmacro{\zgridmin}{ceil(\zmin / \zgriddist) * \zgriddist} \pgfmathsetmacro{\ygridnext}{\ygridmin + \ygriddist} \pgfmathsetmacro{\zgridnext}{\zgridmin + \zgriddist} \pgfmathsetmacro{\ygridmax}{floor(\ymax / \ygriddist) * \ygriddist} \pgfmathsetmacro{\zgridmax}{floor(\zmax / \zgriddist) * \zgriddist} \pgfmathsetmacro{\xtickmin}{ceil(\xmin / \pgfkeysvalueof{/pgfplots/xtick distance}) * \pgfkeysvalueof{/pgfplots/xtick distance}} \pgfmathsetmacro{\ytickmin}{ceil(\ymin / \pgfkeysvalueof{/pgfplots/ytick distance}) * \pgfkeysvalueof{/pgfplots/ytick distance}} \pgfmathsetmacro{\ztickmin}{ceil(\zmin / \pgfkeysvalueof{/pgfplots/ztick distance}) * \pgfkeysvalueof{/pgfplots/ztick distance}} \pgfmathsetmacro{\xticknext}{\xtickmin + \pgfkeysvalueof{/pgfplots/xtick distance}} \pgfmathsetmacro{\yticknext}{\ytickmin + \pgfkeysvalueof{/pgfplots/ytick distance}} \pgfmathsetmacro{\zticknext}{\ztickmin + \pgfkeysvalueof{/pgfplots/ztick distance}} \pgfmathsetmacro{\xtickmax}{floor(\xmax / \pgfkeysvalueof{/pgfplots/xtick distance}) * \pgfkeysvalueof{/pgfplots/xtick distance}} \pgfmathsetmacro{\ytickmax}{floor(\ymax / \pgfkeysvalueof{/pgfplots/ytick distance}) * \pgfkeysvalueof{/pgfplots/ytick distance}} \pgfmathsetmacro{\ztickmax}{floor(\zmax / \pgfkeysvalueof{/pgfplots/ztick distance}) * \pgfkeysvalueof{/pgfplots/ztick distance}} \pgfmathsetmacro{\tickylength}{\pgfkeysvalueof{/pgfplots/major tick length}/1cm*0.5/\pgfkeysvalueof{/pgfplots/ytick distance}} \pgfmathsetmacro{\tickzlength}{\pgfkeysvalueof{/pgfplots/major tick length}/1cm*0.5/\pgfkeysvalueof{/pgfplots/ztick distance}} \pgfplotsonlayer{axis background} \draw[gray!50] \foreach \y in {\ygridmin,\ygridnext,...,\ygridmax}{(0,\y,\zmin) -- (0,\y,\zmax)}; \draw[gray!50] \foreach \z in {\zgridmin,\zgridnext,...,\zgridmax}{(0,\ymin,\z) -- (0,\ymax,\z)}; \endpgfplotsonlayer \pgfplotsonlayer{axis ticks} \draw \foreach \x in {\xtickmin,\xticknext,...,\xtickmax}{(\x,0,-\tickzlength) -- (\x,0,\tickzlength)}; \draw \foreach \y in {\ytickmin,\yticknext,...,\ytickmax}{(0,\y,-\tickzlength) -- (0,\y,\tickzlength)}; \draw \foreach \z in {\ztickmin,\zticknext,...,\ztickmax}{(0,-\tickylength,\z) -- (0,\tickylength,\z)}; \endpgfplotsonlayer } } } \begin{document} \begin{tikzpicture} \begin{axis}[ 3d_style, xmin=-9.2, xmax=9.2, ymin=-5.2, ymax=5.2, zmin=-5.2, zmax=5.2, ] \end{axis} \end{tikzpicture} \end{document}

I'm using luacode environments to assemble plot code for pgfplots. For many plots that works perfectly fine even with tikzexternalize. However, I have one plot where it does not work and the error message is cryptic. I reduced it to: \documentclass{article} \usepackage{pgfplots} \usepackage{luacode} \usetikzlibrary{external} \tikzexternalize \begin{document} %\tikzexternaldisable % doesn't compile with externalization, don't know why \begin{tikzpicture} \begin{axis} \begin{luacode*} local t = {} table.insert(t, "(0, 0)") table.insert(t, "(1, 1)") tex.print("\\addplot coordinates {") tex.print(table.concat(t)) tex.print("};") \end{luacode*} \end{axis} \end{tikzpicture} \end{document} So I used to get an error message like this: File ended while scanning use of \tikzexternal@laTeX@collect@until@end@tikzpicture I thought it might be related to a percent sign in the lua code (which I used for string.format), but I removed them. Now the strings are assembled a bit more manually. The problem persists, however, I don't get an error message any more. It just fails and it also does not create a main-figure0.log file, only the .md5 file. So what is going on?

I am trying to fill between area for a specific plot within a groupplot environment. I have already tried to follow the pgfplot manual which is pretty clear with respect to the name path abd \path[] ... but I just always get the same weird outcome (see picture below). Since I was using the x-axis as the delimitation for the fill between, I started trying to use something else to check if something would change. Below is my MWE: \usepackage{tikz} \usepackage{pgfplots} \usepgfplotslibrary{fillbetween} \usepackage{textcomp} \pgfplotsset{compat=1.18} \usepackage{siunitx} \usepackage{tikzscale} \usetikzlibrary{pgfplots.groupplots} \usetikzlibrary{decorations.markings} \begin{document} \begin{tikzpicture} \begin{groupplot}[ group style={ group name = 4L_keywaveform_sim_S6currentstress, group size = 1 by 1, vertical sep = 15pt }, clip=true, enlargelimits=false, height = 0.75\textwidth, width = \textwidth, axis x line = bottom, axis y line = left, xlabel={$t$}, xlabel style={align=right, anchor=west, xshift=5.8cm, yshift=0.6cm}, x axis line style={shorten >=-15pt}, xmin=0, xmax=12.5, ymajorgrids=true, yminorgrids = true, xmajorgrids=true, grid style={dashed}, set layers,cell picture=true, ] \nextgroupplot[ymin=0, %Position colunm 1 by row 1 ymax=15, ytick align = outside, ytick pos = left, axis y line = left, ylabel = {$y$}, legend columns=1, ] \addplot[color=blue, name path global = teste1, domain=0:15, postaction={decorate},% ------ decoration={markings, % ------ mark=between positions 0.05 and 1 step (1/10)*\pgfdecoratedpathlength with {\arrow{Latex}}, }, ] {x}; \label{test}; \addlegendentry{$x$}; \addplot[color=red, name path global = teste2, domain=0:15] {-3 + x^2}; \path[name path global = teste3] (axis cs:0,5) -- (axis cs:12.5,5); \addplot[blue, fill=blue, fill opacity=0.4] fill between[of= teste1 and teste3]; \end{groupplot} \end{tikzpicture} \end{document} The MWE consists of only 1by1 groupplot for simplificativo purpose. But the issue persists for n by m groupplot. EDIT/UPDATE: By investigating a bit further, it seems that the decoration arguments are messing up with the fill between. I do not know the reason for that, though. Thanks,

I'm using the tikzplotlib code below to generate two Plots. I then place them in two subfloats. As you can see in the final latex output, the figure looks rather ugly with the two plots differently sized and not aligned. What can i do to achieve the same size of the plots and to align them properly. Maybe worth noting, i have several of these figures with multiple subfloats in my document. Python: import matplotlib.pyplot as plt import tikzplotlib import numpy as np x1=np.arange(0,10)*10e9 x2=np.arange(0,1000) y1=np.random.randn(1,len(x1))[0] y2=0.01*x2*np.random.randn(1,len(x2))[0] KIT_green=(0/255,150/255,130/255) KIT_blue=(70/255,100/255,170/255) plt.figure() plt.plot(x2,y2,label="second trace",color=KIT_green) plt.xlabel(r"Time $t$ (in \si{\milli\second})") plt.ylabel(r"Amplitude $S_{11}$ \\ (some measurement) \\ (and another meaningless line) (in \si{\volt})"); tikzplotlib.save("subfigs_left.tikz",extra_axis_parameters=["ylabel style={align=center}"],axis_width="5cm",axis_height="5cm") plt.figure() plt.plot(x1,y1,label="first trace",color=KIT_blue) plt.xlabel(r"Time $t$ (in \si{\milli\second})") plt.ylabel(r"Amplitude $S_{11}$, $S_{35}$ (in \si{\volt})"); tikzplotlib.save("subfigs_right.tikz",extra_axis_parameters=["ylabel style={align=center}"],axis_width="5cm",axis_height="5cm") LaTeX: \documentclass[11pt]{article} \usepackage[utf8]{inputenc} \usepackage{graphicx} \usepackage{subfig} \usepackage{siunitx} \usepackage{tikz} \usepackage{pgfplots} \usepackage{tikzscale} \begin{document} \begin{figure} \centering \subfloat[Plot 1: this shows this]{\includegraphics[width=0.4\textwidth]{subfigs_left.tikz}} \qquad \subfloat[Plot 2: and this shows that.

I want to show a chart by the package pgfplots only on a subsequent slide of a frame. However using \uncover or \visible on the chart generates an error: Package pgfplots Error: Could not read table file '" {Other Categories} 0 0 . } with the MWE below. If I remove the \uncover, the file compiles and produces a static frame as I show below. How can I display the chart only on certain slides?

I would like the surface of the cylinder to reach the blue arcs towards left (y-axis) but not passing through them. How can I achieve that? \documentclass[border=3mm]{standalone} \usepackage{pgfplots} \pgfplotsset{compat=1.15} \begin{document} \begin{tikzpicture} \begin{axis}[% axis lines=middle, ticks=none, zmin=-2, zmax=2, xmin=-3, xmax=3, ymin=-1, ymax=3, view/h=125, view/v=25 ] \addplot3[% opacity = 0.02, fill opacity=0.5, mesh/interior colormap name=hot, surf, colormap/hot, faceted color=black, z buffer = sort, samples = 50, variable = \u, variable y = \v, domain = 0:360, y domain = -3:3, ] ({cos(u)}, {max(v,cos(v))}, {sin(u)}); % ARCS \addplot3[% variable= \t, mesh, blue!80!, semithick, samples=30, opacity = 0.025, z buffer = sort, domain= 0:180, ] ({sin(t)}, {sin(t)}, {cos(t)}); \addplot3[% variable= \t, mesh, blue!80!, semithick, samples=30, opacity = 0.025, z buffer = sort, domain= 0:-180, ] ({sin(t)}, {-sin(t)}, {cos(t)}); \end{axis} \end{tikzpicture} \end{document}
