Essential Chart will support stacking a series with a group. In order to group a stacking series with another stacking series in the chart control, you can use a property called StackingGroup of the chart series with the desired group name.
The below code snippet demonstrates the usage of StackingGroup for a series in the chart control.
[C#]
ChartSeries series1 = new ChartSeries("Series 1"); series1.Type = ChartSeriesType.StackingColumn; // specifing group name . series1.StackingGroup = "FirstGroup"; ChartSeries series2 = new ChartSeries("Series 2"); series2.Type = ChartSeriesType.StackingColumn; // specifing group name . series2.StackingGroup = "SecondGroup"; ChartSeries series3 = new ChartSeries("Series 3"); series3.Type = ChartSeriesType.StackingColumn; // specifing group name . series3.StackingGroup = "FirstGroup";
