# How can I draw this line figure with arrows using TikZ?

I need this figure drawn in TikZ for work. How do I do it?

So far, I have:

\documentclass[tikz,border=2mm]{standalone}
\usepackage{lmodern}
\begin{document}
\begin{tikzpicture}[y=2cm, font=\sffamily\small]

\draw[->] (0,0) -- (4.5,0) node[below] {};

\foreach \i in {1,2,3,4} \draw (\i,1mm) -- (\i,-1mm) node[below] {\i};

\end{tikzpicture}
\end{document}

• Is the unequal spacing and the displacement of the arrows intended? – Henri Menke Dec 26 '15 at 16:33
• I did it with paint. The distance of the nodes (1,2,3 ..) is the same. Sorry – Solid Dec 26 '15 at 16:38
• Welcome to Tex SE. Have you searched the site for similar drawings to replicate? – Alenanno Dec 26 '15 at 16:39
• I don't know the type of latex is this. – Solid Dec 26 '15 at 16:41
• could you post a MWE of the code you already wrote trying to achieve this? – Rico Dec 26 '15 at 16:41

Here, without the unequal spacing and displaced arrows, but with TikZ.

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{shapes.arrows}
\begin{document}
\begin{tikzpicture}[scale=0.5,
down arrow/.style = {
single arrow, draw,
minimum height=2.5em,
transform shape,
rotate=-90,
}]
\draw (0,0) -- (10,0);
\foreach \i in {1,...,9}
\draw (\i,0.3) -- (\i,-0.3) node[below] {\i};
\foreach \i in {1,2,4,6,7,9}
\node[down arrow] at (\i,1) {};
\end{tikzpicture}
\end{document}
