I have a situation where I want to lable the sample points of a line segment, and also label the smaller line segments connecting those sample points. My labels are really cluttered right now. How can I make this more proper? \documentclass[tikz,border=1cm]{standalone} \begin{document} \begin{tikzpicture} \draw[thick,->] (-1,0) -- (5,0) node[below left] {\(x\)}; \fill (0.5,0) circle[radius = 3pt] node[above] {point}; \fill[gray] (0.5,0) circle[radius = 1.5pt]; \draw[] (0.5,0) -- (0.5,-2) -- (5,-2) node[right] {individual sample point}; \draw[line width = 6pt] (2,0) -- (3.5,0) node[above,pos=0.5]{line segment}; \foreach[count = \c from 1] \x in {2,2.5,...,3.5} { \fill[gray] (\x,0) circle[radius = 1.5pt]; \draw[] (\x,0) -- (4,-1); \ifnum\c=4\else\draw[thick,gray] (\x,0) -- ++(0.5,0);\fi } \draw[](4,-1) -- (5,-1) node[right] {multiple sample points}; \foreach[count = \c from 1] \x in {2.25,2.75,...,3.25} { \draw[] (\x,0) -- (4,-1.5); } \draw[](4,-1.5) -- (5,-1.5) node[right] {one or more line segments}; \end{tikzpicture} \end{document}

I am trying to create a new math symbol. Could someone please help me with it? My current code: \documentclass[12pt]{report} \RequirePackage{tikz} \newcommand{\eq}{\begin{tikzpicture}% [scale=.175, line width=0.5pt] \draw (-1,1) -- (0,0); \draw (0,1) -- (-0.5,0.5); \draw (0,-1) -- (-1,0); \draw (-0.5,-0.5) -- (-1,-1); \end{tikzpicture}} \begin{document} \[ u - \eq - u \] \end{document} However, the symbol I am actually going for is this: I was using it for something like this:

I am typesetting a play in LaTeX. I would like all the lines to be numbered but of course the stage directions etc. should be excluded from the line numbers. In MS Word, this is easily by telling word to exclude some lines from the numbering, it then looks like this: Is there a way to acheive this in LaTeX too? My preferred way would be to tell the document to have line numbers everywhere except: in lines where there are stage directions (maybe this can be done by some command?) in lines that consist only of headings (i.e. scene numbering etc.). The numbers should only start after the actual play starts, not yet in the Dramatis Personae. Thanks in advance for any help!

I use the code generated by pstoedit from an .eps image. The code below gives me a composite black in 4 colors. What settings should I add to the .mp image for the CMYK model to ensure it is printed only in black (without CMY)? I also tried \MPcolor{black} but it gives me an error.

I wanted to adapt this nice solution for my purposes. • I want to extend the x- and y-axes a bit. 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.... y= ] \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 was eager to write this question, namely, in a better way. I myself wrote it down as: $\text{Let } E(n)=\displaystyle\int\limits_{0}^{\pi} \sin^{2n+1}(x)\cos^{28}{x}dx$ $\text{Let } J(n)=\displaystyle\int\limits_{0}^{1} x^n(1-x)^n (1-2x)^{2n}dx$ then determine the ratio $\dfrac{E(a)}{J(14)}$ in decimal form. Where $a=e^{\pi-1} \displaystyle\int\limits_{-\pi/2}^{\pi/2} \dfrac{\tan^3{x} \sec^2{x}}{\tan^5{x}+\tan{x}}dx$ Round $a$ to the nearest integer. Find closed form using repeated reduction formulae. (Avoid using Beta or Gamma functions.) Help me in doing so.

I have a table, it looks like this: But I'm having a few problems. What's the best way to set the keys? The table contains a 2×2 groupplot and a formula next to another plot (this plot can be larger than the others). I want to use the entire width of the yellow box! What's the best way to set this up? (In the MWE, I only set it visually.) The formula should be vertically centered or top-centered, whichever is easier to set or looks better. The number of columns with the numbers (1111, 2222,...) is variable, but I don't think that matters because: The entire table should have the page width. Note: The reason I put everything in newcommands is that the original table is actually a pgfplotstable - I'm simulating it here. \documentclass[paper=a5]{scrartcl} \usepackage[margin=14mm, showframe=true]{geometry} \usepackage{amsmath} \usepackage{pgfplots} \pgfplotsset{compat=1.18} \usepgfplotslibrary{groupplots} \usepackage{colortbl}% \rowcolor, \cellcolor \usepackage{diagbox}% \diagbox \usepackage{hhline}% \hhline{~|-------|} and so on \newcommand\Mydiagrams{ \begin{tikzpicture}[] \begin{groupplot}[group style={group size=2 by 2}, height=30mm,width=49mm, no marks, title style={inner sep=0pt} ] \nextgroupplot[title=plot 1] \addplot{x}; \nextgroupplot[title=plot 2] \addplot{x^2}; \nextgroupplot[title=plot 3] \addplot{x^3}; \nextgroupplot[title=plot 4] \addplot{x^4}; \end{groupplot} \end{tikzpicture}} \newcommand\Myheaddiagram{% \begin{tikzpicture}[] \begin{axis}[ height=30mm,width=49mm, no marks, title style={inner sep=0pt}, title=plot 0, ] \addplot{sin(deg(x))+2}; \end{axis} \end{tikzpicture}} \newcommand\Headformula{% $F(a,b,c) =\displaystyle\sum\limits_{v=0}^k \binom{a}{b} a^v (b+c)^{n-v}$ }% \newcommand\Myhead{% \begin{tabular}[t]{| @{}l@{} | @{}c@{} |}% tabular for linebreaks \arrayrulecolor{blue} \Headformula & \Myheaddiagram \\ \multicolumn{2}{|c|}{\Mydiagrams} \end{tabular} }% \begin{document} \section{Diagramms} \setlength\arrayrulewidth{2pt}% test: correctness of the rules \footnotesize\sffamily% wanted \noindent\begin{tabular}{c | c | *{7}{c} |c|} \hhline{~| *{8}{-} |} & \multicolumn{8}{l|}{\cellcolor{yellow}\Myhead} & \multicolumn{1}{c}{c'} \\ \hhline{-| *{8}{-} -|} \rowcolor{pink} aaa & bbb & 0.1111 & .2222 & .3333 & .4444 & .5555 & .6666 & .7777 & ccc \\ aaa & bbb & 0.1111 & .2222 & .3333 & .4444 & .5555 & .6666 & .7777 & ccc \\ aaa & bbb & 0.1111 & .2222 & .3333 & .4444 & .5555 & .6666 & .7777 & ccc \\ \hline aaa & \diagbox{p}{k} & 0.1111 & .2222 & .3333 & .4444 & .5555 & .6666 & .7777 & \diagbox{p}{k} \\ \end{tabular} \end{document}

I'm trying to pass values to the command declared in setuphead and evaluate them in the command. Following the example at https://wiki.contextgarden.net/Command/_startsection under the heading of "Settings (instance variant)", it appears that the key-value pairs are being passed to the command. However, I do not understand either how if/then/else works in ConTeXt and/or when commands are expanded to their values. In the example below, the MySection command works because the test is for whether or not a user variable of pw has any value or something like that. But the MySectionBroken command fails because the attempted test on the value of user-variable ct is always false and there is not pw for the scenario when ct is equal to character l. It appears that \structureuservariable{pw} is converted to its value in \starttabulate but \structureuservariable{ct} is not in the if test. I see the many, many doifelse... commands in the big book of ConTeXt commands but did not see anything on the wiki that describes how they function. Would please point me to where this is explained? Thank you. P.S. I should've explained that I'd like to pass a column type and, when it is paragraph, a column width. I need the section number to remain more left than the text when it wraps. And, even though I'd be glad to learn of other ways to accomplish this, I'd really like to understand how the conditionals work in ConTeXt. Thanks. \setuplayout[ height=4in, width=4in ] \define[2]\MySection{% \placetable[middle,none][]{}{ \doifelsesomething{\structureuservariable{pw}}{% \starttabulate[|l|p(\structureuservariable{pw})|][frame=on] }{% \starttabulate[|l|l|][frame=on] }% \NC #1 \NC #2 \NC \NR \stoptabulate} } \define[2]\MySectionBroken{% \placetable[middle,none][]{}{ \doifelsevalue{\structureuservariable{ct}}{l}{% \starttabulate[|l|l|][frame=on] }{% \starttabulate[|l|p(\structureuservariable{pw})|][frame=on] }% \NC #1 \NC #2 \NC \NR \stoptabulate} } \setuphead[section][ conversion=Romannumerals, sectionstopper={.}, command=\MySection, ] \starttext \startsection[title={Title One}][ct={l}] A paragraph \ldots \stopsection \startsection[title={Title Two}][ct={p},pw={30mm}] A paragraph \ldots \stopsection \startsection[title={Title Three is\\a Multi-liner}][ct={p},pw={50mm}] A paragraph \ldots \stopsection \stoptext

Following MnWE: \documentclass[a4paper]{article} \usepackage{tabularx} \usepackage{tabu} \usepackage{makecell} \begin{document} \begin{tabularx}{\textwidth}{|@{}>{\raggedright}p{4.5cm}X|} \makecell[cl]{NAME} & \rule[-\dp\strutbox]{3pt}{\headheight}On geometry in KOMA scripts \end{tabularx}% \end{document} I saw the solution but in fact, we cannot see that this is vertically centered because the row is as high as the column. Due to the \rule in my situation it is different and so one can see, that there is no vertical centering. I suspect that the first column is as high as the text, so not as high als the 2nd column. How to get the 1st column vertically centered??? To be honest, there is another requirement: want to use in a header. So I search for solutions which can be fit precisely into given height and width.

This question comes out of the comments from this question and I didn't want to add more to it. (If the former should be deleted, I will; please let me know.) The issues were that 1) I didn't want the whitespace before a section title to start at the end of the previous page when there was some space left after the preceding paragraph; 2) I wanted some whitespace before the title but, when the title starts a new page, not as as much whitespace because the headerdistance adds the appearence of additional whitespace. The use of framedtext provided by @MaxChernoff in this answer worked as shown below. The whitespace between the header rule and the title is about the same as for a title surrounded by text; and Section III is moved to the next page and spaced properly. The space before a title is split into two values, one in the framedtext option of toffset which is like forced and fixed; and another in the setuphead option beforesection using \blank which is suppressed at the top of a new page. \setuplayout[ height=4in, width=4in, topspace=0.33in, top=0.33in, topdistance=0in, headerdistance=3mm, footerdistance=0.150in, header=\lineheight, footer=\lineheight, bottom=0.255in, bottomdistance=0in, bottomspace=0in] \settextcontent[header][text] [middletext][section][section] \setupheader[text][ style=\sc, after={\hrule height 0.8pt} ] \define[2]\MySection{% \framedtext [frame=off, width=\textwidth, offset=none, toffset=3mm, align=center]{#1 #2} } \setuphead[section][ conversion=Romannumerals, sectionstopper={.}, align=center, command=\MySection, beforesection={\blank[2mm]}, before=, after={\blank[5mm]}, aftersection=\blank[back], style={\tfa\it}, ] \starttext % \showframe \startsection[title={Title One},marking={Header One}] A paragraph of the to fill the line to observe the spacing. \stopsection \startsection[title={Title Two},marking={Header Two}] \input{ward} A few more word to extend the paragrahp down two lines in order to push the head forward one line. \stopsection \startsection[title={Title Three},,marking={Header Three}] A paragraph of the to fill the line to observe the spacing. \stopsection \stoptext Next, I tried to render the same result using \testpage as suggested by @mickep, figuring that \framedtext is performing about the same test to determine if the framed title can all fit on the page. I think that part works but I haven't been able to get the spacing to be correct. My reasoning/expectation was that, in the example below, the beforesection={\testpage[4]\blank[2mm]}, will test for four lines left on the page. If there are four lines, it will write 2mm of whitespace; if not, it will insert a pagebreak and the 2mm of whitespace will be suppressed at the top of the page. Then the before={\blank[force,fixed,3mm]}, will write 3mm of whitespace whether at the top of a page or not since it is forced. But that is not what is occurring; and, instead, there is extra whitespace when the title is at the top of a page and less when it is surrounded by text. I apologize for being so dense and slow to understand this, but would you please tell me what I'm failing to observe hereto make the two methods render the same results? Thank you. \setuplayout[ height=4in, width=4in, topspace=0.33in, top=0.33in, topdistance=0in, headerdistance=3mm, footerdistance=0.150in, header=\lineheight, footer=\lineheight, bottom=0.255in, bottomdistance=0in, bottomspace=0in] \settextcontent[header][text] [middletext][section][section] \setupheader[text][ style=\sc, after={\hrule height 0.8pt} ] \setuphead[section][ conversion=Romannumerals, sectionstopper={.}, align=center, beforesection={\testpage[4]\blank[2mm]}, before={\blank[force,fixed,3mm]}, after={\blank[5mm]}, aftersection=\blank[back], style={\tfa\it}, ] \starttext % \showframe \startsection[title={Title One},marking={Header One}] A paragraph of the to fill the line to observe the spacing. \stopsection \startsection[title={Title Two},marking={Header Two}] \input{ward} A few more word to extend the paragrahp down two lines in order to push the head forward one line. \stopsection \startsection[title={Title Three},,marking={Header Three}] A paragraph of the to fill the line to observe the spacing. \stopsection \stoptext

I am trying to use text in a particular font (in this case, a Helvetica clone) without bringing on an entire package and/or forcing the user to use a particular package. A minimal example is below: \documentclass{article} \usepackage{tikz} \begin{document}\noindent This is document text. \begin{center} \begin{tikzpicture} \begin{scope}[every node/.style={transform shape}] \renewcommand*{\sfdefault}{phv} \node {\resizebox{!}{0.5cm}{\sffamily WOOHOO!}}; \end{scope} \end{tikzpicture} \end{center} This is more document text. \end{document} However, I get different results with different engines, as shown: My questions: (1) why doesn't LuaLaTeX show the same result as PDFLaTeX? (2) What is the "right" (read: most portable) way to include a single piece of Helvetica (or some other font) in this manner without dragging in an entire package or forcing the use of a particular TeX engine?

Perhaps silly question, but how compatible are the macros of the older PiCTeX package, Plain compatible, with the newer picture environment, accesible through the autopict package from the graphics-pln package through either Plain or eplain ?

Here are two different bits of code that difer by exactly one letter: Number 1: \documentclass{amsart} \usepackage[all]{xy} \begin{document} \begin{displaymath} \xymatrix{ { \begin{tabular}{c|c} \hline $x_2$ & 7 \\ \hline $x_3$ & 4 \\ \hline \end{tabular} } \ar@(ul,dl)[]_{\pi^0} } \end{displaymath} \end{document} Number 2: \documentclass{amsart} \usepackage[all]{xy} \begin{document} \begin{displaymath} \xymatrix{ { \begin{tabular}{c|c} \hline $x_2$ & 7 \\ \hline $x_3$ & 4 \\ \hline \end{tabular} } \ar@(l,dl)[]_{\pi^0} } \end{displaymath} \end{document} The difference is that in number 2, the arrow is modified with @(l,dl) while in number 1 it is modified with @(ul,dl) Number 1 doesn't compile. Number 2 does but looks ugly. I'd like Number 1 to compile and look better than Number 2 in the way it should. Since I know it will come up: no, I'm not willing to switch to tikz. Yes, I know tikz is better. But I know the syntax for xypic and have been using it for sneaking up on twenty years and I just turned 40 and am thus officially allowed to be a stick in the mud about things.

With pdfLaTeX, the following code works as expected, including rendering the Cyrillic portion of the text: \documentclass{article} \usepackage[russian,english]{babel} % Optional: for hyphenation \babeltags{russian=russian} \usepackage[T2A,T1]{fontenc} \usepackage{newtx} \DeclareFontFamilySubstitution{T2A}{\rmdefault}{Tempora-TLF} % for Cyrillic \begin{document} `\textrussian{Тихонов}' is often transliterated as `Tychonoff'. \end{document} How can I similarly produce the Cyrillic characters if, instead, I use the LuaLaTeX engine and Lucida Bright font, as in the following? % !TEX program = lualatex \documentclass{article} \usepackage{fontspec} \usepackage[russian,english]{babel} % Optional: for hyphenation \babeltags{russian=russian} \babelfont{rm}[Scale=0.92,DefaultFeatures={Ligatures=TeX}]{LucidaBrightOT.otf} \begin{document} `\textrussian{Тихонов}' is often transliterated as `Tychonoff'. \end{document}

I'd like to label each term of an equation like this: I tried with \underset, \mathop, \underbrace... but, since some terms take more vertical space than others, all the labels are on different heights. This is the closest I got to what I want, using alignat, but still the numerals are not centered: \begin{alignat*}{7} &\frac{\partial u_i}{\partial t} + &&u_j \frac{\partial u_i}{\partial x_j} &&= &&-g\delta_{i3} + &&f\varepsilon_{ij3}u_j - &&\frac{1}{\rho}\frac{\partial p}{\partial x_i} + &&\nu\frac{\partial ^2u_i}{\partial x^2_j} \\ & \text{I} && \text{II} && && \text{III} && \text{IV} && \text{V} && \text{VI} \end{alignat*} How can I label in a clear, aligned way? PS: this is just the equation: $\frac{\partial u_i}{\partial t} + u_j \frac{\partial u_i}{\partial x_j} = -g\delta_{i3} + f\varepsilon_{ij3}u_j - \frac{1}{\rho}\frac{\partial p}{\partial x_i} + \nu\frac{\partial ^2u_i}{\partial x^2_j}$

Is it possible to test within a before option command whether or not the item to be written is at the top of the page? For example, I tried in \setuphead before={\doiftopofpageelse{...true...}{...false...}} and it is always true even when the head item is not being written at the top of the page. Thank you. For example, every section below shows "top of the page". Why? \setuplayout[height=4.7in,width=4in] \setuphead[section][ conversion=Romannumerals, sectionstopper={.}, align=center, before={\blank[0mm]}, beforesection={\doiftopofpageelse{\hrule{top of page}}{\hrule{not top of page}}}, after={\blank[5mm,]}, style={\tfa\it}, ] \starttext \showframe \startsection[title={Title One}] A paragraph of the to fill the line to observe the spacing. \stopsection \startsection[title={Title Two}] \input{ward} \stopsection \startsection[title={Title Three}] A paragraph of the to fill the line to observe the spacing. \stopsection \stoptext Added There are two parts to the item I can't get to work as needed. It occurs when a section's before area is at the bottom of a page and the head title is at the top of the next page. For example, I need to get the whitespace of the before to move to the top of the next page. The second part of it is to know when this occurs such that I can reduce that whitespace by the size of the distance between the header and the text block so the overall space above and below the section header is about even rather than more on the top. Thanks. \setuplayout[height=5.85in,width=4in] \setuphead[section][ conversion=Romannumerals, sectionstopper={.}, align=center, beforesection={{\darkred(beforesection)}}, before={{\darkblue(before)}\blank[force,line]}, after={{\darkblue(after)}}, aftersection={{\darkred(aftersection)}}, style={\tfa\it}, ] \starttext \showframe \startsection[title={Title One}] A paragraph of the to fill the line to observe the spacing. \stopsection \startsection[title={Title Two}] \input{ward} \stopsection \startsection[title={Title Three}] A paragraph of the to fill the line to observe the spacing. \stopsection \stoptext Yet another addition I need to read about \testpage[] but the context wiki site responds with forbidden, here. In the meantime, the framedtext approach as @MaxChernoff provided here appears to be working for a "real" section also. I think I can adjust the toffset by the header distance and add it in \setuphead with a \blank that will be suppressed at the top of a new page only. \setuplayout[height=4.5in,width=4in,] \define[2]\MySection{% \framedtext [frame=on, width=\textwidth, offset=none, toffset=5mm, align=center]{#1 #2} } \setuphead[section][ conversion=Romannumerals, sectionstopper={.}, align=center, command=\MySection, before=, after={\blank[5mm]}, aftersection=\blank[back], style={\tfa\it}, ] \starttext \showframe \startsection[title={Title One}] A paragraph of the to fill the line to observe the spacing. \stopsection \startsection[title={Title Two}] \input{ward} \stopsection \startsection[title={Title Three}] A paragraph of the to fill the line to observe the spacing. \stopsection \stoptext

I want to use siunitx for alignments within a currency table. Perhaps euros are not a scientific unit - but I haven't seen why this might be a problem. I want to use a different font. Anyway there seems to be a strange mixture which leads to a weird result. \documentclass[12pt]{article} \usepackage[margin=2.5cm]{geometry} \usepackage{fontspec} \setmainfont{Bitter}[Ligatures=TeX,Scale=MatchLowercase] \usepackage{tabularx, multirow} \usepackage[locale = DE]{siunitx} \begin{document} \begin{tabular}{S} \textbf{Betrag} \\ 120,00 €\\ -12,00 €\\ \large\textbf{108,00 €}\\ \end{tabular} \end{document} Only the header and the last line are in "Bitter" font. Addtionally I don't understand why the euro sign has an extra space in the 3rd line. The result of the given MWE has two weird aspects: The ammount 120€ and -12€ are NOT in the main font. Is there a way to keep it? the euro sign after -12 has a strange additional space. Is there a way to correct it? (to have only ONE extra space)?

I know that I can make circular diagrams with the nice smartdiagram package, but arrows do not fit perfectly in a imaginary circle. In fact, the diagram is far from a circle when there are only two or three nodes: \documentclass{standalone} \usepackage{smartdiagram} \begin{document} \smartdiagramset{ connection color=red, module shape= circle, circular distance=2cm, uniform color list=white for 6 items, uniform arrow color=true, arrow color=black} \smartdiagram[circular diagram:clockwise]{foo, bar} \end{document} I know also that there are several examples in this site about making circular diagrams without this package, but translating these examples to diagrams with a different numbers of nodes is complex, so I tried an automated solution with tikz (without really knowing what I was doing, I have to admit) so that I only have to modify a list of nodes in \mylist and little more to obtain the result: \documentclass[border=2mm]{standalone} \usepackage{tikz} \usetikzlibrary{arrows.meta} \begin{document} \begin{tikzpicture}[ > = Stealth, every node/.style = {circle, draw, thick, minimum width=1cm, align=center} ] \def\mylist{foo, bar, baz} % play with this \foreach \x [count=\i from 1] in \mylist {\xdef\n{\i}} \def\radio{2cm} % and this if needed \foreach \texto [count=\i from 0] in \mylist{ \pgfmathsetmacro\ang{-\i*360/\n} \node (n\i) at (\ang:\radio) {\texto}; } \foreach \dummy [count=\i from 0] in \mylist{ \pgfmathsetmacro\j{int(mod(\i+1,\n))} \pgfmathsetmacro\angini{-\i*360/\n} \pgfmathsetmacro\angfin{-\j*360/\n} \pgfmathsetmacro\outang{mod(\angini - 90 + 720, 360)} \pgfmathsetmacro\inang {mod(\angfin + 90 + 720, 360)} \draw[->, thick, line width=1.4pt] (n\i) to[out=\outang, in=\inang, looseness=.9] (n\j); % and with the looseness } \end{tikzpicture} \end{document} Mainly it works. The problem is that like in smartdiagram, the arrows don't perfectly follow an imaginary circle, that was the idea behind getting involved in this business. Playing with looseness is possible to correct a bit the curvature of the arrows, but it's tedious and the result is never perfect. So, the result should be ideally near to the image below (that I modified manually in Inkscape) and still require minimal settings to adapt the code to diagrams of n nodes. Fixes of the MWE as well as alternative approaches are welcome. Edit Thank you all for the excellent suggestions. This time, I am truly sorry I can only accept one.
