  <p>I have the following ggplot</p>
  
  <p><img src="https://i.stack.imgur.com/gUGkg.png" alt="enter image description here"></p>
  
  <pre><code>dt &lt;- structure(list(Age.group = structure(1:5, .Label = c("0-29 yrs", "30-49 yrs", "50-64 yrs", "65-79 yrs", "80+ years"), class = "factor"),     Rx.Brufen = c(4.91767279891635, 24.849329416471, 39.384529665324,     42.0512030516413, 45.0282816501013), Brufen.C.I = c(9.49857407873833,     10.4942035949849, 11.0935906177108, 16.7322917304551, 18.5232702433842   ), Brufen.declined = c(1.25219908256281, 1.1156980249761,     1.18510539437499, 0.73845826559561, 1.00121613129538)), .Names = c("Age.group", "Rx.Brufen", "Brufen.C.I", "Brufen.declined"), row.names = c(NA, -5L), class = "data.frame")
  
  dt.m &lt;- melt(dt, 1)
  
  colnames(dt.m)[2] &lt;- "Rx"
  colnames(dt.m)[3] &lt;- "Proportion"
  ggplot(dt.m, aes(x=Age.group,y=Proportion, fill=Rx)) +
      geom_bar() +
      labs(x="Age Group", y="Proportion %",fill = "") +
      theme(legend.position=c(.5, .9), legend.direction = "horizontal" ) +
      ylim(c(0,100))
  </code></pre>
  
  <p>I would like to plot the actual values, as percentages (inside the bars for the green and red bars,  and just above for the blue ones, since they won't fit inside). Can someone advise how to achieve this ?</p>
