[nfbcs] Creating Flow Charts

[Greg Kearney]

Yo can do this in TeX the typesetting system. It is done entirely with text entry.

Here is an example of the LaTeX code and the resulting flowchart

\documentclass{article}



\usepackage[latin1]{inputenc}
\usepackage{tikz}
\usetikzlibrary{shapes,arrows}
\begin{document}
\pagestyle{empty}




% 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=5em, text centered, rounded corners, minimum height=4em]

\tikzstyle{line}
 = [draw, -latex']

\tikzstyle{cloud}
 = [draw, ellipse,fill=red!20, node distance=3cm,
    minimum height=2em]
    

\begin{tikzpicture}
[node distance = 2cm, auto]
    
% Place nodes

    
\node [block] (init) {initialize model}
;
    
\node [cloud, left of=init] (expert) {expert}
;
    
\node [cloud, right of=init] (system) {system}
;
    
\node [block, below of=init] (identify) {identify candidate models}
;
    
\node [block, below of=identify] (evaluate) {evaluate candidate models}
;
    
\node [block, left of=evaluate, node distance=3cm] (update) {update model}
;
    
\node [decision, below of=evaluate] (decide) {is best candidate better?}
;
    
\node [block, below of=decide, node distance=3cm] (stop) {stop}
;
    
% Draw edges

    
\path
 [line] (init) -- (identify);
    
\path
 [line] (identify) -- (evaluate);
    
\path
 [line] (evaluate) -- (decide);
    
\path [line] (decide) -| node [near start] {yes}
 (update);
    
\path
 [line] (update) |- (identify);
    
\path [line] (decide) -- node {no}
(stop);
    
\path
 [line,dashed] (expert) -- (init);
    
\path
 [line,dashed] (system) -- (init);
    
\path
 [line,dashed] (system) |- (evaluate);

\end{tikzpicture}
