General ⇒ A very long arrow

[Stefanie]

Hi guys,

i need to insert a very long arrow in my latex document, almost as long as the width of my text. do you know about a latex command which can do that? i don't mind using an extra package.

You could use the standard picture environment and draw a vector or use the pgf/tikZ package and do the according thing.


Best regards

Another option would be to use the \xrightarrow or \xleftarrow comands provided by the amsmath package, as the following example suggests:

Code: Select all

\documentclass{article}
\usepackage{amsmath}

\begin{document}

\[ \xrightarrow{\hspace*{3cm}} \]

\[ \xrightarrow{\hspace*{8cm}} \]

\[ \xrightarrow{\hspace*{10cm}} \]

\[ \xleftarrow{\hspace*{2cm}} \]

\[ \xleftarrow{\hspace*{7cm}} \]

\[ \xleftarrow{\hspace*{11cm}} \]

\end{document}

thank you gmedina, that was exactly what i was looking for. tikz and the picture environment are too complicated for what i had in mind (and difficult to get right). this solution is much quicker.

I need also long arrows, left and right, to put a broken line in up of a table. That's my solution:

Code: Select all

\renewcommand{\arraystretch}{1.3}
\begin{table}[!h]
\begin{center}
\caption{Secuencia de emisiones}
\hspace*{-8pt}$\xleftarrow{\hspace*{2.6cm}}\textrm{10 segundos}\xrightarrow{\hspace*{2.6cm}}$  
\begin{tabular}{c|cccccccc|c}

\multicolumn{1}{c}{} & \multicolumn{8}{|c|}{Intervalos entre emisión 0,2 segundos} & \\[-2pt]
\cmidrule{2-9}
\end{tabular}
\end{center}
\end{table}

The packages amsmath and booktabs are needed.
