title: Getting the point on a scatter chart with TimeSeries
body: <p>After zooming or panning a scatter chart with a TimeSeries, the pointIndex points is calculated based on what is on the screen. </p>
  
  <p>If there are 10 items in a series, when the chart is first show, item 1 is at pointIndex 0. Item 2 is at pointIndex 1, etc. However, once you zoom or pan, then the pointIndex starts with what is SHOWN, not the index of the item in the series. </p>
  
  <p>Has anyone figured out a way to get the series index value of the point and not the panned/zoomed index value?</p>
