I want to draw a block diagram for a software app and I need two shapes which I couldn't find on the Internet. The shapes are a parallelogram and a rectangle with double side margins.
One is for data and the other for a predefined process. They look like this:
Does anyone know how could I draw those two shapes (maybe using TikZ)?
I am not sure if something like this is what you need; I changed from the old \tikzstyle to \tikzset:
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{shapes,arrows,shapes.multipart}
\begin{document}
\pagestyle{empty}
% Define block styles
\tikzset{
decision/.style = {diamond, draw, fill=blue!20,
text width=4.5em, text badly centered, node distance=3cm, inner sep=0pt},
block/.style = {rectangle, draw, fill=blue!20,
text width=5em, text centered, rounded corners, minimum height=4em},
line/.style = {draw, -latex'},
cloud/.style = {draw, ellipse,fill=red!20, node distance=3cm,
minimum height=2em},
subroutine/.style = {draw,rectangle split, rectangle split horizontal,
rectangle split parts=3,minimum height=1cm,
rectangle split part fill={red!50, green!50, blue!20, yellow!50}},
connector/.style = {draw,circle,node distance=3cm,fill=yellow!20},
data/.style = {draw, trapezium,node distance=3cm,fill=olive!20}
}
\begin{tikzpicture}[node distance = 2cm, auto]
% Place nodes
\node [block] (init) {initialize model};
\node [data, left of=init] (expert) {expert};
\node [connector, 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] (test) {test};
\node [subroutine, below of=test, node distance=3cm] (sub) {part1\nodepart{two}part2\nodepart{three}part3};
% 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}(test);
\path [line,dashed] (test) -- (sub);
\path [line,dashed] (expert) -- (init);
\path [line,dashed] (system) -- (init);
\path [line,dashed] (system) |- (evaluate);
\end{tikzpicture}
\end{document}
Use [xshift=...mm] or [yshift=...mm] for node.

The double side margin rectangle can be created using a
rectangle split, the parallelogram using atrapezium:
