title: .net graphing library with dragable data points
body: <p>I am looking for a graphing library that I can use in a C# application. I am hoping to find one that is free and would allow me to create a line graph that end-users could modify by dragging data points.</p>
  
  <p>If anyone knows of one that can do this let me know.</p>
  
  <p>Thanks.</p>
