title: Interactive spline chart for C# WPF/Winforms
body: <p>I'm looking to buy or build a spline chart (just like one <a href="http://visifire.com/silverlight_spline_charts_gallery.php" rel="nofollow">here</a>) in C# .NET for which the data points can be draged by mouse and the resulting underlying dataset changes.</p>
  
  <p>Could some one point me in the right direction?</p>
