title: get mark position in ms charts on mouse click
body: <p>I m making a chart using MS Charts.
  Now the chart has mark points from where i want to get the coordinates
  if user clicks on the mark points.</p>
  
  <p>I want interactivity in the chart such that on clicking on the mark points i can retrive the cordinates (x-axis and y-axis) for the mark points.</p>
  
  <p>For example for the graph:-</p>
  
  <p><img src="https://i.stack.imgur.com/HuCEH.jpg" alt="graph"></p>
  
  <p>on clicking on the orange dots or blue dots i want to get the cordinates for that point, </p>
  
  <p>for example the first blue point is (10/11/2011, 49)</p>
  
  <p>Thanks</p>
