title: WPF toolkit charting Lineseries styling
body: <p>Is it possible to change the thickness of the LineSeries? 
  Is it possible to show LineSeries as dashed lines?
  I have othe question about AreaSeries, no matter what all my Area Series are drawing from x-Axis. What I want is that I can draw let say a area for these four point (2,2), (2,6), (8,6), (8,2).
  How can I manage it?</p>
