ChartGroups Object (PowerPoint)
Represents one or more series plotted in a chart with the same format.
A ChartGroups collection is a collection of all the ChartGroup objects in the specified chart. A chart contains one or more chart groups, each chart group contains one or more series, and each series contains one or more points. For example, a single chart might contain both a line chart group, containing all the series plotted with the line chart format, and a bar chart group, containing all the series plotted with the bar chart format.
Although the following code applies to Microsoft Word, you can readily modify it to apply to PowerPoint.
