Point Object (PowerPoint)
Represents a single point in a series in a chart.
The Point object is a member of the Points collection. The Points collection contains all the points in one series.
Although the following code applies to Microsoft Word, you can readily modify it to apply to PowerPoint.
Use Points(Index), where Index is the point index number, to return a single Point object. Points are numbered from left to right on 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 the first chart in the active document. The specified series must be a 2-D line, scatter, or radar series.
