title: Removing label lines from ZedGraph pie-chart
body: <p>I am using ZedGraph to create a pie chart, and adding items to it using the AddPieSlice() method, all overloads of which require a label parameter. I pass in null for this as I don't want any labels for the segments. However the graph still draws a line coming out of each segment that I think is supposed to join it to it's non-existent label.</p>
  
  <p>Is there any way to remove these lines?</p>
  
  <p>Thanks in advance!</p>
