title: Twosided Barplot in R with different data
body: <p>I was wondering if it's possible to get a two sided barplot (e.g. <a href="https://stackoverflow.com/questions/34140476/two-sided-bar-plot-ordered-by-date">Two sided bar plot ordered by date</a>) that shows above <strong>Data A</strong> and below <strong>Data B</strong> of each X-Value. </p>
  
  <p><strong>Data A</strong> would be for example the age of a person and <strong>Data B</strong> the size of the same person. The problem with this and the main difference to the examples above: A and B have obviously totally different units/ylims. </p>
  
  <p><strong>Example:</strong></p>
  
  <pre><code>X = c("Anna","Manuel","Laura","Jeanne") # Name of the Person
  A = c(12,18,22,10)     # Age in years
  B = c(112,186,165,120) # Size in cm 
  </code></pre>
  
  <p>Any ideas how to solve this? I don't mind a horizontal or a vertical solution. </p>
  
  <p>Thank you very much!</p>
