title: Core-Plot: Removing line that connects points in Scatterplot?
body: <p>I would like to simply show scatterplot points. Actually, two sets of scatterplot points with different colors.</p>
  
  <p>However, it seems that the default condition of a scatterplot is to connect the dots. I've tried to set the CPTMutableLineStyle properties to nil, but the line still shows.</p>
