title: Label on each bar ggplot in R
body: <p>I'm plotting the age of the participants from a survey i've made. To plot this barchart I'm using this code:</p>
  
  <pre><code>plot_ly(y = dataIdade$total, x = dataIdade$Idade, name = "Idade", type = "bar")
  </code></pre>
  
  <p>But as you guys can see, the label of X is displaying only some numbers, I need to display all numbers on each drawed bar at least.</p>

  <p>To tryout my code you can use this:</p>
  
  <pre><code>dataTeste=data.frame(
    individual=paste( seq(1,60), sep=""),
    value=sample( seq(10,100), 60, replace=T)
  )
  
  plot_ly(y = dataTeste$value, x = dataTeste$individual, name = "Idade", type = "bar")
  </code></pre>
  
  <p>it's quite close</p>
