I am trying to achieve the chart as in the image attached.
I tried with this code but I have difficult to insert the texts.
Please suggest me if there is a more elegant way to achieve this.
Regards Leo
the code is:
\documentclass{article}
\usepackage{pgf}
\usepackage{tikz}
\usepackage{inputenc}
\usetikzlibrary{arrows,automata,shadows}
\usetikzlibrary{positioning}
\usetikzlibrary{calc}
\tikzset{
state/.style={
rectangle,
draw=black,
minimum height=2em,
inner sep=2pt,
text centered,
drop shadow
},
}
