# How do I get a straight line in \begin{tikzpicture}[decoration=Koch snowflake]? [closed]

The following code

\documentclass{standalone}

\usepackage{tikz}
\usetikzlibrary{decorations.fractals}
\usepackage{pgfplots}

\begin{document}

\begin{tikzpicture}[scale=3,decoration=Koch snowflake]
\draw decorate{ (0,0) -- (3,0) };
\draw decorate{ decorate{ (0,-1) -- (3,-1) }};
\draw decorate{ decorate{ decorate{ (0,-2) -- (3,-2) }}};
\draw decorate{ decorate{ decorate{ decorate{ (0,-3) -- (3,-3) }}}};
\end{tikzpicture}

\end{document}


Gives me the following picture:

To emphasize the initiator and I'd like the first figure to be a straight line, like on this picture:

The problem is that I don't quite understand what the numbers { (0,0) -- (3,0) } mean, and being new to TeX, I also don't know where to look it up.

• @Leo, in case you were just reading the literally first page of the PGF/TikZ documentation, I really recommend reading through the first tutorial, and everything will be very clear. – Turion Jul 30 '14 at 14:58
• @Sigur an answer maybe? – percusse Jul 30 '14 at 20:55
