title: Spotfire: How to use trellis to show 4 elements: 3 years + set of records older than 3 years?
body: <p>Lets say I have the data about some kind of requests.
  I have column determining request's creation date.
  I wish to show the requestes Trellis'ed by this date but not the standard way.
  I wish all the requests with creation date older than 2013-01-01 to be grouppped in one trellis graph. 
  I also would like to retain the possibility to have information on both year and quarter level as it is available for typical date column.</p>
  
  <p>The image below show sth similar to what I need but the Empty section comes as the last one and I need it with different label and on the left hand side rather than as it is now on the right hand side.</p>
  
  <p>Any ideas ?</p>
