title: vb.net return actual chart x and y values on mousemove
body: <p>In my simple vb.net chart that displays a particular series, I would like to obtain running values of the actual values in the chart.  I can already obtain the x-y coordinates, which is easy (e.x and e.y) - but wondering if there is a available method to convert the coordinates to the values related to the chart itself.</p>
  
  <p>I need to use the mousemove event rather than mousedown.</p>
  
  <p>I wish to transfer these actual values to a textbox on the form.</p>
  
  <p>Thanks - burnt out trying to figure this out on my own.</p>
