title: How to space overlapping annotations
body: <p>I want to annotate the bars in a graph with some text but if the bars are close together and have comparable height, the annotations are above ea. other and thus hard to read (the coordinates for the annotations were taken from the bar position and height).</p>
  
  <p>Is there a way to shift one of them if there is a collision?</p>
  
  <p><strong>Edit:</strong> The bars are very thin and very close sometimes so just aligning vertically doesn't solve the problem...</p>
  
  <p>A picture might clarify things:
