title: Tableau Line Graph doesn't connect the current month
body: <p>Hello as you can see in the image,
  I have created a worksheet in which I'm trying to show the line graph trend of the number of tickets per month per track level(see filters)</p>
  
  <p>However when i turn on the filter " Show Current Month" to True,
  The line graph doesnt connect to the the current month which is Jan 2016</p>
  
  <p>Is this beacuse Jan is a new Year in the graph ?
  What can be the solution to the issue ?</p>
