Hi Tony,
Thanks for using Syncfusion products.
Stacking column charts require two or more series. They are similar to column charts except that the y values stack on top of each other in the specified series order.
Please refer the following code snippet to achieve this:
<code>
[CS]
MVCChartModel chartModel=new MVCChartModel();
ChartSeries series=new ChartSeries("Series1", ChartSeriesType.StackingColumn);
series.Points.Add(1,400);
series.Points.Add(2,500);
series.Points.Add(3,600);
series.Points.Add(4,500);
chartModel.Series.Add(series);
ChartSeries series1=new ChartSeries("Series2", ChartSeriesType.StackingColumn);
series1.Points.Add(1,200);
series1.Points.Add(2,300);
series1.Points.Add(3,400);
series1.Points.Add(4,500);
chartModel.Series.Add(series);
</code>
