# Easiest way of drawing a graph in LaTeX

So, I'm looking for the easiest way of drawing something like this. It's a simple diagram.

Is the picture environment the most appropiate one?

• I would use the tikzpicture environment to create it. – dustin Jun 2 '13 at 16:56

One possibility using TikZ and multipart rectangles:

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{shapes.multipart,shapes.arrows}

\tikzset{
mystack/.style={
draw,
rectangle split,
rectangle split parts=#1,
text width=2cm,
align=center,
anchor=north east,
font=\ttfamily}
}

\begin{document}

\begin{tikzpicture}
% The stack to the left
\node[mystack=2] at (0,0) (sta1)
{stack\nodepart{two}\rule{0pt}{2cm}};
\draw[white,line width=3pt] (sta1.south west) -- (sta1.south east);
\node[fill=red!50,single arrow,rotate=-90,text width=10pt] at (sta1) {};

% The stack to the right
\node[mystack=3] at (5,0) (sta2)
{0$\times$AAA\nodepart{two}0$\times\cdots$\nodepart{three}\rule{0pt}{1.5cm}};
\draw[white,line width=3pt] (sta2.south west) -- (sta2.south east);

% The red and black arrows
\draw[line width=2pt,red,->]
([xshift=1cm]sta1.east) -- ++(20pt,0);
\draw[line width=1pt,<-]
([xshift=5pt]sta2.two split east) -- ++(10pt,0) node[right] {ESP};
\end{tikzpicture}

\end{document}


• +1 for \draw[white ... at lower border and \rule{0pt}... to fix stack height. Could you explain how do you know each stack line height is 5mm? – Ignasi Jun 3 '13 at 8:55
• @Ignasi thanks for the vote! Regarding your question, I'm a little confused; which are the stack lines you are referring to? – Gonzalo Medina Jun 3 '13 at 13:31
• In sta1 you use \rule{0pt}{2cm} while in \sta2 rule heigth is only 1.5cm, and both stacks show same height. How did you decide this 5mm difference? – Ignasi Jun 3 '13 at 14:14
• @Ignasi ah, now I understand. Well, the values were just found "by eye" (I'm not sure if that's the right English expression). – Gonzalo Medina Jun 3 '13 at 14:19

I think that a good choice is the pstricks package, or any other design/draw software.

Use graphics package to include .jpg, .eps, .png... files in the .tex file.

Here you can see some examples:

If you want to write me, you can do it in spanish at NOTHINGmika2ikeNOTHING@gmail.com. I'm starting learning PSTricks. If you are using it, remember to compile with xelatex or use other options like the ones you can find here:
