# Descriptive diagram with direction

I'm new to Tikz and am working on converting SmartArt from MS PowerPoint to LaTeX. One of my diagrams looks like this:

I'm aware of the package smartdiagram, and I found the "descriptive diagram", which seems somewhat close to the above. But I am trying to show the steps of a process AND describe each of those steps (hence the directed hexagons down the left). Is there a way to do this that already exists in smartdiagram? Or do I need to draw my own tikzpicture?

Or, without the smartdiagram package:

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{shapes.symbols,positioning}

\definecolor{myblue}{RGB}{79,129,189}

\tikzset{
myshape/.style={
shape=signal,
fill=myblue,
minimum height=1.5cm,
minimum width=1.5cm,
text=white,
signal pointer angle=130,
signal to=east,
signal from=west,
rotate=-90,
transform shape
},
mytext/.style={
draw=myblue,
text width=7cm,
minimum height=1.15cm,
thick,
outer sep=0pt
}
}
\newcounter{tmp}
\newcommand\MyDesc[3][]{
\stepcounter{tmp}%
\node[myshape,#1] (desc\thetmp) {};
\node[font=\color{white}] at (desc\thetmp) {#2};
\node[mytext,anchor=north west] at (desc\thetmp.north west)
{%
\parbox[t]{2em}{\hfill$\bullet$\hfill\null}%
\parbox[t]{\dimexpr\linewidth-2em\relax}{#3}%
};
}

\begin{document}

\begin{tikzpicture}[]
\MyDesc{Foo 1}{Description 1}
\MyDesc[below = 1.5cm of desc1.north]{Foo 2}{Description 2}
\MyDesc[below = 1.5cm of desc2.north]{Foo 3}{Description 3}
\end{tikzpicture}

\end{document}

Great. Suppose I want to get rid of the bullet. Do I just delete \parbox[t]{2em}{\hfill$\bullet$\hfill\null}%? –  user1577636 Mar 15 '14 at 18:34
@user1577636 Yes. Additionally, you change \parbox[t]{\dimexpr\linewidth-2em\relax}{#3} to \parbox[t]{\linewidth}{#3}. –  Gonzalo Medina Mar 15 '14 at 18:36
@user1577636 I simplified the code in my updated answer. –  Gonzalo Medina Mar 15 '14 at 23:33

With a small patch, it is possible to achieve:

which is far from being perfect, but looks like the reference picture.

The code:

\documentclass[12pt]{article}
\usepackage{smartdiagram}
\usetikzlibrary{shapes.symbols}

\tikzset{description title/.append style={
signal,
signal to=south,
signal from=north,
yshift=-0.65cm,
}
}
\begin{document}
\begin{center}
\smartdiagramset{description title width=2cm,
description title text width=1.75cm,
descriptive items y sep=2,
description text width=5.75cm,
module minimum height=1.25cm}
\smartdiagram[descriptive diagram]{%
{Set up,The set up operation consist of..},
{Run, {After having set up the program, you must run..}},
{Analyse, You must check what did with analytical tools like..},}
\end{center}
\end{document}

I'm planning to add this feature in the new release, thanks for the suggestion. –  Claudio Fiandrino Mar 15 '14 at 18:10
Yep. In the temporary workaround above, is there a way to scale down the whole thing (i.e. an equivalent to scale = 0.5 in tikz)? –  user1577636 Mar 15 '14 at 20:55
@user1577636: sure, you can exploit \scale from graphicx package; then \scale{0.5}{\smartdiagram[..]{..}}. –  Claudio Fiandrino Mar 16 '14 at 8:35
