title: How I can define the limits of a bar using geom_bar() in R?
body: <p>I'd like to personalise my geom_bar() to define my superior and inferior limits for each bar. I mean, I would like to put the beginning of a bar in wherever point in my axis and its ending as the same way.</p>
  
  <p>I would like to recreate this <a href="http://www.marca.com/2012/03/02/multimedia/graficos/1330720526.html" rel="nofollow">example</a> using R and ggplot2.</p>
  
  <p>Does someone any idea how to do this?</p>
  
  <p>Thanks :)</p>
