title: MS Chart, X axis dates and cursor interaction when X value is indexed
body: <p>Good afternoon,</p>
  
  <p>Wow what a title.</p>
  
  <p>Basically here is the thing.</p>
  
  <p>If have a time series which is not continuous.</p>
  
  <p>Hence, since I use the IsXValueIndexed property of the Series (set to true) to collapse the space between the separate points.</p>
  
  <p>That works fine, however I would now like to be able to recover a point's detail in from the graph (X and Y values) and display them in a label on the form.</p>
  
  <p>Hence, I use the following event:</p>
  
  <pre><code>void myChart_CursorPositionChanging(object sender, CursorEventArgs e)
      {
          if (!double.IsNaN(e.NewPosition))
          {
              if (e.Axis.AxisName == AxisName.X)
              {
                  lbl_selDate.Content = DateTime.FromOADate(e.NewPosition);
              }
              else
              {
                  lbl_selValue.Content = e.NewPosition;
              }
          }
      }
  </code></pre>
  
  <p>The problem is that the date is incorrect... I cannot find the right conversion method to recover this damned timestamp.</p>
  
  <p>Can you by any chance help me out?</p>
  
  <p>Thanks!</p>
  
  <p>Jeremie</p>
