Flussdiagramm divergierende und konvergierende Pfeile

Nov 24 2020

Frage: Ich habe Probleme, die Pfeile im Flussdiagramm zu teilen. Ich habe versucht, ähnlichen Code zu betrachten, kann ihn aber scheinbar nicht reproduzieren. Wie kann ich die ideale Ausgabe erhalten?

Relevante Forschung:

  • Abweichende Pfeile, tikz / pgf - Flussdiagramm
  • Anpassen des vertikalen und horizontalen Abstands zwischen Knoten im Tikz-Flussdiagramm
  • Konvergierende und divergierende Knoten in einem Flussdiagramm

MWE:

\begin{document}


\begin{center}

    % Define block styles
    \tikzstyle{decision} = [diamond, draw, fill=blue!20, 
        text width=4.5em, text badly centered, node distance=3cm, inner sep=0pt]
    \tikzstyle{block} = [rectangle, draw, fill=blue!20, 
        text width=4.5cm, text badly centered, rounded corners, minimum height=4em, minimum width=5cm]
    \tikzstyle{line} = [draw, -latex']
    % \tikzstyle{cloud} = [draw, ellipse,fill=red!20, node distance=3cm, minimum height=2em]



    \begin{tikzpicture}[node distance = 2.5cm, auto]
    % Place nodes
    \node [block, below of=dav] (install)           {Install fan, heat sink, thermal dough and 4 jumpers on the board};
    \node [block, below of=install] (voltage)       {Complete Voltage Testing};
    \node [block, below of=voltage] (recordvalue)   {Record serial number Voltage Testing is a pass or fail to spreadsheet};
    \node [block, below left  of=recordvalue, node distance=6.5cm] (flashTX) {Flash as Tx};
    \node [block, below right of=recordvalue, node distance=6.5cm] (flashRX) {Flash as Rx};
    \node [block, below of=flashTX] (testflashTX)   {Test Tx with \textit{Golden Rx}};
    \node [block, below of=flashRX] (testflashRX)   {Test Rx with \textit{Golden Tx}};     
    
    \node [decision, below of=recordvalue, node distance=10cm] (passfail)   {Pass/Fail}; 
    

    % Draw edges
    \path [line] (dav) -- (install);
    \path [line] (install) -- (voltage);
    \path [line] (voltage) -- (recordvalue);
    \path [line] (recordvalue) |- (flashTX);
    \path [line] (recordvalue) |- (flashRX);


    \path [line] (flashTX) -- (testflashTX);
    \path [line] (flashRX) -- (testflashRX);

Bearbeiten: Im Diagramm werden neue Knoten hinzugefügt, wie Sie es in der bearbeiteten Frage benötigen.

In MWE (Minimal Working Example) unten werden im Vergleich zu Ihrem Codefragment die Änderungen vorgenommen:

  • Knoten sind in drei Ketten organisiert (unter Verwendung der TikZ-Bibliothek chains), wobei für die Positionierung der verwendeten Knotenbibliothek positioningund ihrer Syntax (dadurch werden die Abstände zwischen Knoten gleich bestimmt durch node distance = <below> and <right>)
  • Knoten in Ketten sind durch Pfeile verbunden, die durch joindie im chainsPaket definierte Anweisung gezeichnet werden
  • Verbindungen zwischen Knoten werden an vier Stellen mithilfe von Code unterbrochen suspend join
  • Verbindungen zwischen Knoten, die in nicht berücksichtigt werden join, werden separat gezeichnet
\documentclass[tikz, margin=3mm]{standalone}
\usetikzlibrary{arrows.meta,
                chains,
                positioning,
                shapes.geometric}
