int CBCGPChartSeries::GetGroupID ( ) const

Returns series group ID.

Use this method to retrieve series group ID. A group ID specifies how series are grouped in stacked and full stacked mode. By default all series have group ID set to 0 and stacked together. To implement side-by-side stacked series assign different group IDs to desired series. For example, if you have 4 series and assign to series one and three ID 1, you'll see two stacked groups, where stack values are calculated separately for series two/four and one/three.
