I have the chart (axis X - dates, axis Y - numbers), data source is Dictonary. How i can get data (or indexes) in selection range of chart? e.g. data: 10/10/2012 , 10 10/11/2012 , 11 10/12/2012 , 12 10/13/2012 , 13 10/14/2012 , 14
Then user select on chart range from 10/11/2012 to 10/13/2012, can i get X values from 10/11/2012 to 10/13/2012 ?
Thank you!
