title: How to hide label of data points in line chart
body: <p>Please refer to the picture below.</p>
  
  <p>Basically I have a C# chart control with some series on it, I have one series with label (the red line in the picture) but I want to be able to toggle the label on/off. Is that possible? I can't find any properties that can do so.</p>
  
  <p>Thanks a lot.</p>
