title: How can I add a percentage label to the bars in this chart?
body: <p>I have a chart (it started out as a histogram but I changed it to a bar chart so that I could use percentages more easily):</p>
  
  <p><a href="https://i.stack.imgur.com/ygSpG.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ygSpG.png" alt="enter image description here"></a></p>
  
  <p>This is the code for the chart:</p>
  
  <pre><code>ggplot(df, aes(as.Date(callclosed), y = (..count..)/sum(..count..))) +
        geom_bar(fill = "skyblue1",
                 colour = "black") +
        scale_y_continuous(labels = scales::percent, limits = c(0, 0.06)) +
        scale_x_date(date_breaks = "1 day", date_labels = "%d-%b-%y") +
        theme(axis.text.x = element_text(angle = 90))
  </code></pre>
  
  <p>How can I add labels to the top of each bar that shows the associated percentage?</p>
