The tikz package seems to have what you want.
\documentclass{article} \usepackage{tikz} \usetikzlibrary{snakes} \begin{document} \begin{tikzpicture}[snake=zigzag, line before snake = 5mm, line after snake = 5mm] % draw horizontal line \draw (0,0) -- (2,0); \draw[snake] (2,0) -- (4,0); \draw (4,0) -- (5,0); \draw[snake] (5,0) -- (7,0); % draw vertical lines \foreach \x in {0,1,2,4,5,7} \draw (\x cm,3pt) -- (\x cm,-3pt); % draw nodes \draw (0,0) node[below=3pt] {$ 0 $} node[above=3pt] {$ $}; \draw (1,0) node[below=3pt] {$ 1 $} node[above=3pt] {$ 10 $}; \draw (2,0) node[below=3pt] {$ 2 $} node[above=3pt] {$ 20 $}; \draw (3,0) node[below=3pt] {$ $} node[above=3pt] {$ $}; \draw (4,0) node[below=3pt] {$ 5 $} node[above=3pt] {$ 50 $}; \draw (5,0) node[below=3pt] {$ 6 $} node[above=3pt] {$ 60 $}; \draw (6,0) node[below=3pt] {$ $} node[above=3pt] {$ $}; \draw (7,0) node[below=3pt] {$ n $} node[above=3pt] {$ 10n $}; \end{tikzpicture} \end{document}
I’m not too expert with tikz, but this does give a good timeline, which looks like:
