When a new begin{tikzpicture}[xshift=2cm] is used, it creates the TikZ picture 2 cm to the right of existing TikZ picture (X shift).

But, somehow that doesn't seem to work here and the decoration (snake line) is also not aligned properly.

I was expecting the following:

But I get this:

Note: I have used the same code in the first TikZ picture hence the right box also has the same diagram. I will change that later.

Code:

documentclass{article}

usepackage{tikz}

usetikzlibrary{positioning}

usetikzlibrary{arrows}

usetikzlibrary{backgrounds}

usetikzlibrary{fit}

usetikzlibrary{decorations.pathmorphing}



tikzset{squarenode/.style = {

    shape  = rectangle,

    fill   = gray!50,

    draw   = black,

    thick,

    minimum height = 1cm,

    minimum width  = 1cm

}}



tikzset{circlenode/.style = {

    shape  = circle,

    fill   = blue!20,

    draw   = blue,

    thick,

    minimum size = 1cm

}}



tikzset{help lines/.style=very thin}

tikzset{My Grid/.style={help lines,color=blue!50}}
