title: ggplot2 - box plot questions on misalignment
body: <p>I am having the following challenges making a plot:</p>
  
  <ol>
  <li>I am trying to do a 'grouped' box plot - but it appears that the box plots are not showing up near the corresponding x axis group.  So It's not easy to see which group each plot belongs to.</li>
  <li>I am trying to add in an icon for the 'mean' value which right now is a triangle.  However these aren't moving with the grouped boxplots.</li>
  <li>I don't want the triangle icon for the mean value to show up in the legend - I can't figure out how to remove this.</li>
  <li>Whenever I try to add text I just want one value either for the median or the mean - not something repeated 50x.</li>
  </ol>
