title: How to draw overlapping area graph in ggplot2 using geom_area()
body: <p>I am trying to draw overlapping areas within ggplot. However, the following code is resulting in stacked bars:</p>
  <pre><code>library(ggplot2)
  df &lt;- data.frame(Status = c(rep(&quot;Close&quot;, 20),rep(&quot;Open&quot;, 30)),
                        Year = sample(c(2012, 2013, 2014, 2015, 2016), 50, replace = TRUE))
  
  ggplot(df, aes(x = Year, fill = Status)) + 
    geom_area(stat = 'bin', binwidth = 1)
  </code></pre>
  <p>The outcome will be stacked area graph.</p>

  <p>What if I want to draw an overlapping area graph to compare each year's status?</p>
