  Hi Team,

  I created dynamic drag drop line chart, now i am unable to drag to a particular number. i.e. from 2000 to 1000, it will be either 1000+ or below 1000.

  In my use case, user will drag to a particular point but exactly to a particular is not happening.

  Your valuable suggestions please.

  Sometimes multiple values are represented by single pixel co-ordinate. This happens when the number of values on axis is greater than actual pixels available in given chart container. For example: If the height of the chart is 200px and the axis range is 0 to 1000. Each pixel co-ordinate will represent 5 axis value co-ordinates.
  You can overcome this issue by rounding off the selected value as per your requirement. You can also take a look at this example which uses ySnapDistance to round off the pixel positions.
  You can also re-adjust the height and width of the chart and see if it makes any changes.
