pgfplots

I have a figure drawn with pgfplots where I cite a reference in the legend. the issue I have is when I try to scale the whole figure, I noticed that the green hyper link for the reference is not scaled and inserted at the original place. Here is an ECM with on the one hand the figure in whole size, and on the other hand the figure scaled. \documentclass{article} \usepackage{biblatex} \usepackage{hyperref} \usepackage{pgfplots} \pgfplotsset{compat=1.5} \addbibresource{biblatex-examples.bib} \begin{document} \begin{tikzpicture} \begin{axis} \addplot[red, domain=-3e-3:3e-3, samples=51]{exp(-x^2 / (2e-3^2)) / (1e-3 * sqrt(2*pi))}; \addlegendentry{Text \cite{aksin}} \end{axis} \end{tikzpicture} % \begin{tikzpicture}[scale=0.9] \begin{axis} \addplot[red, domain=-3e-3:3e-3, samples=51]{exp(-x^2 / (2e-3^2)) / (1e-3 * sqrt(2*pi))}; \addlegendentry{Text \cite{aksin}} \end{axis} \end{tikzpicture} \printbibliography \end{document} On the linked export, we see that the second green boxed is not over the reference [1], but over the place it would have been if the figure were not scaled. Is it possible to set the correct location for this box ?

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 am trying to recreate this picture from the College Board. I am able to recreate the image with the x-axis labeled in fourths (pi). However, the original shows each label being 1/8 (pi). Each time I try to use specific xtick and xlabel, the spacing is incorrect. Is there an easier way I can do this?

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 trying to create slope fields based on several examples I have seen on here. My issue is that when I change my equation (the slope field I want to draw) my image does not appear to be square. I would like it uniform. The uniformity changes based on what function I plot. Is there a way to fix this? The image attached is from AP Classroom. Note the uniformity all the way around and how it is square, or flush. that is what I am looking for. \documentclass{standalone} \usepackage{pgfplots} \usetikzlibrary{arrows.meta} \pgfplotsset{compat=1.18} \begin{document} \centering \begin{tikzpicture} \begin{axis}[ view={0}{90}, axis lines=middle, axis equal image, width=10cm, xmin=-5.5, xmax=5.5, ymin=-5.5, ymax=5.5, xtick={-4,-2,2,4}, ytick={-4,-2,2,4}, xlabel=$x$, ylabel=$y$, axis line style={thick, -{Triangle[scale=1.2]}}, clip=false ] \addplot3[ thick, color=red, declare function={ f(\x,\y) = \x; norm(\x,\y) = sqrt(1 + (f(\x,\y))^2); }, quiver={ u={1/norm(x,y)}, v={f(x,y)/norm(x,y)}, scale arrows=0.4, every arrow/.append style={-} }, % -------------------------------- samples=15, domain=-4.2:4.2, domain y=-4.2:4.2 ] {0}; \end{axis} \end{tikzpicture} \end{document}

I want to use the entire \textwidth at a table, so I chose tabularx. The table contains plots (all the same size) and boxes with titles that contain varying amounts of text or lines. The "title boxes" should all be top-aligned, all have the same width and for each row (!) the same height. This means that the "title boxes" in row 1 have the same height, and those in row 3 also have the same height; but possibly a different height than in row 1. What's the best way to configure this? I've put the "title boxes" also into tabularx tables; but perhaps multirow would be more suitable here (?). I often have problems with overfull / underfull hbox warnings here. I don't know what the ideal solution for this. Note: I plan to disable the main table's rules later; I've set \setlength\arrayrulewidth{2pt} here to better visualize the dimensions. \documentclass[paper=a5]{scrarticle} \usepackage[margin=14mm, showframe]{geometry} \usepackage{tabularx} % \usepackage{multirow}% needed? \usepackage{pgfplots} \pgfplotsset{compat=1.18} \usepackage{lipsum}% dummy text \newcommand\mytitle[1]{% {\begin{tabularx}{\linewidth}{|X|} \hline #1 \\ \hline \end{tabularx}} } \newcommand\myplot[1]{% \begin{tikzpicture}[baseline] \begin{axis}[width=\linewidth, height=30mm] \addplot[#1, mark=*]{x^4}; \end{axis} \end{tikzpicture}} \newcolumntype{Y}{% hspaces should be as small as possible @{\hspace{1.5pt}}X@{\hspace{1.5pt}}} \setlength\arrayrulewidth{2pt}% to see the effects \begin{document} \noindent\begin{tabularx}{\textwidth}{| Y | Y |} % Title 1 (row 1, column 1) ================== \mytitle{Title 1: \lipsum[1][1-2]} % Title 2 (row 1, column 2) ================== & \mytitle{Title 2: \lipsum[1][1]} \\ % Plot 1 (row 2, column 1) ================== \myplot{brown} % Plot 2 (row 2, column 2) ================== & \myplot{red} \\ \hline % Title 3 (row 3, column 1) ================== \mytitle{Title 3: \lipsum[1][2]} % Title 4 (row 3, column 2) ================== & \mytitle{Title 4: \lipsum[1][1-4]} \\ % Plot 3 (row 4, column 1) ================== \myplot{blue} % Plot 4 (row 4, column 2) ================== & \myplot{orange} \\ \end{tabularx} \end{document}

I have a 2×2 groupplot (where the first plot should be replaced by a title "Supertitle") with titles in boxes. These "title boxes" should all have the same width, and boxes in the same row should have the same height. I achieved this using \vphantom{} because I didn't find a better method. How can I configure the settings such that the entire groupplot has a width of \textwidth? And a horizontal space between the columns like \tabcolsep (or something similar)? Is there a elegant way to do this by package keys? (resizebox etc. would certainly work, but that would be less elegant.) Ideally, it should stay a groupplot.

But, when I set enlarge y limits={upper, abs=0.125} it creates a strange gap (ymin=0 is no longer respected, and restrict y to domain=0:1 seems to have no effect). • Secondly, what's the best way to configure it so that bars with very small y-values ​​are also visible here? • Unfortunately, I saw this too late: I would also like to eliminate this x-gap between the first bar and the y-axis! \documentclass[margin=5pt]{standalone} \usepackage{pgfplots} \pgfplotsset{compat=1.18} \begin{document} \begin{tikzpicture}[font=\footnotesize, declare function={ binom(\n,\p,\k)=\n!/(\k!*(\n-\k)!)*\p^\k*(1-\p)^(\n-\k); } ] \begin{axis}[%y=8mm, no effect ymin=0, xmin=0, axis lines=left, axis line style={-latex}, xlabel={$k$}, ylabel={$P(X=k)$}, x label style={at={(axis description cs:1,0)}, anchor=south east, inner xsep=0pt }, y label style={at={(axis description cs:0,1)}, rotate = -90, anchor=north west, inner ysep=0pt, }, yticklabel style={ /pgf/number format/fixed, /pgf/number format/fixed zerofill, /pgf/number format/precision=2 }, ybar=0pt, bar width=1, bar shift=0pt, samples at={0,...,13}, variable=\k, enlarge x limits={upper, abs=0.785}, enlarge y limits={upper, abs=0.125}, %restrict y to domain=0:1,% no effect.... ] \addplot [fill=gray!25] {binom(13, 0.4, k)}; %\addplot [fill=orange, samples at={0,...,4}] {binom(12,0.4,k)}; %\addplot [fill=cyan, samples at={7}] {binom(12,0.4,k)}; \end{axis} \end{tikzpicture} \end{document}

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?

Consider the following snippet: \documentclass{article} \usepackage{tikz} \usepackage{pgfplots} \pgfplotsset{compat=1.18} \usepgfplotslibrary{colorbrewer, patchplots} \begin{document} \begin{tikzpicture} \begin{axis}[cycle list/Set2] \addplot+[patch, patch type=cubic spline, point meta=none, red] coordinates { (-1,-1) (1,1) (-1/3,{(-1/3)^3}) (1/3,{(1/3)^3}) }; \end{axis} \end{tikzpicture} \end{document} which is based off the cubic spline patch example in the PGFPLOTS manual. As expected it produces a red curve. However, I am having trouble changing the colour to be one from a set. For example swapping red for index of colormap=2 of Set2 causes the line to revert to black. What is the correct means of applying a uniform colour from a colour map to all of the patches?

I was plotting as usual and then after saving one of my plots as a pgf and then compiling LaTeX it didn't work anymore. As far as I'm aware of, I didn't change anything it just so happen to top working. The code I'm using to make an example plot is the following: import matplotlib . pyplot as plt import numpy as np from pathlib import Path import matplotlib .cm as cm import tikzplotlib import matplotlib as mpl mpl.rcParams['mathtext.fontset'] = 'cm' # Latex font mpl.rcParams['font.family'] = 'serif' mpl.rcParams['font.serif'] = ['cmr10'] mpl.rcParams['axes.formatter.use_mathtext'] = True # Erzeuge eine Liste von x-Werten x = np.linspace(-5, 10, 100) a= [2,8,8,2] b=[2,2,8,2] U_1=2 U_2=8 I_1=2 I_2=8 # Berechne die entsprechenden y-Werte für die Funktion y = x y = x # Plotte die Funktion plt.plot(x, y) plt.plot(a,b, color = 'crimson', marker='', linestyle='dashed') plt.plot(U_1,I_1, color = 'green', marker='x', linestyle='',label='$(U_{1}, I_{1})$', markersize=14) plt.plot(U_2,I_2, color = 'orange', marker='x', linestyle='',label='$(U_{1}, I_{2})$', markersize=14) plt.plot(U_2,I_1, color = 'purple', marker='x', linestyle='',label='$(U_{2}, I_{2})$', markersize=14) # Beschriftungen für die Achsen hinzufügen plt.xlabel('$I$ / arbitrary units') plt.ylabel('$U$ / arbitrary units') # Titel für den Plot hinzufügen plt.title('Beispiel Fit') plt.legend(loc='upper left') # Grid hinzufügen plt.grid(True) # Den Plot anzeigen plt.savefig('example.pgf', format='pgf', bbox_inches='tight', pad_inches = 0) plt.show() I tried multiple things and I'm pretty sure that the problem is in the commands mpl.rcParams['font.serif'] = ['cmr10'] mpl.rcParams['axes.formatter.use_mathtext'] = True Sure I can commen them out but then (more bovious for other plots) the axes will be in a weird font and if I have a different, let's say logarithmic scaling, it wont look like 10^{-21} like in latex and the font is different as well.

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 have a ~50 sample dataset I'd like to put into a table. Because there's only one variable to display, a single column chart looks ridiculous and wastes a lot of space. Is there a way I can get it to fill the page with data (i.e., wrap the data horizontally and vertically)? I'm imagining something like this image, with the header row taking up the full width, and the data cells in between. I tried using pgfplotstable, but I couldn't really wrap my head around it.

I've copied an example bar plot from the manual. I had a little trouble to tweak the style of the legend. Here is what I've got. \begin{tikzpicture} \begin{axis}[ x tick label style={/pgf/number format/1000 sep=}, ylabel=\emph{Population}, xlabel=\emph{years}, enlargelimits=0.15, % legend style={at={(0.5,-0.15)}, % anchor=north,legend columns=-1}, ybar, bar width=9pt, ] \addplot [black!100!white,fill=black!100!white] coordinates { % \addplot [black!20!black,fill=black!50!white] coordinates { (1930,50e6) (1940,33e6) (1950,40e6) (1960,50e6) (1970,70e6) }; \addplot [black!30!white,fill=black!30!white] coordinates { (1930,38e6) (1940,42e6) (1950,43e6) (1960,45e6) (1970,65e6) }; \legend{Far,Near} \end{axis} \end{tikzpicture} The plot look likes this However, I want the legend to be

Sorry, I have no code to submit, mostly because I have no idea how to do this. I want to type up my homework (I can do the homework by hand) and I am looking for a simple method that I can use repetitively on different equations; without having to code each equation; to make/produce/draw the slope field of that equation. Currently, I have typed up the rest of my homework with latex, but have no good example from the internet to follow. I want to put the slope fields for both $\frac{\mathrm{d}y}{\mathrm{d}x}=2x$ and $\frac{\mathrm{d}y}{\mathrm{d}x}=x\sqrt{x}$ into my homework. My system is Fedora 19. Any suggestions? ps. sorry if this is a poor quality question. I just used the suggested tags.
