Represents a single point in a series on the specified chart. The Point object is a member of the Points collection, which contains all the points in the specified series.
Using the Point Object
Use Points(index), where index is the point's index number, to return a single Point object. Points are numbered from left to right in the series.
Points(1) is the leftmost point, and
Points(Points.Count) is the rightmost point. The following example sets the marker style for the third point in series one. For this example to work, series one must be a 2-D line, scatter, or radar series.
