title: How to update a single graph in chart from multiple async threads?
body: <pre><code> Parallel.foreach(list&lt;&gt; , a=&gt;  
      {  
      // do some operation  
           chart1.Series[0].Points.AddXY(x, y);  
      });  
  </code></pre>
  
  <p>I want to draw different lines for each thread invoked in parallel. Is there anyway to do this?</p>
