Hi Saad,
Thanks for your interest in Syncfusion products.
As far as your requirement is on showing each and every point on a series of a StackingArea Chart, we have created a sample on it. You can download the sample from the below given link,
Series Hover Point Here, we have used annotations to display the mouse hover points.
The below given lines inside the Series.MouseMove will help to get the exact mouse-hover point.
Point pt = e.MouseEventArgs.GetPosition(chart1.Areas[0]);
double x = Math.Truncate(chart1.Areas[0].PointToValue(chart1.Areas[0].PrimaryAxis, pt));
double y = Math.Truncate(chart1.Areas[0].PointToValue(chart1.Areas[0].SecondaryAxis, pt));
Please let us know if you have further queries.
Regards,
Pavithra.J
