Remarks

The stacked bar series displays data as a collection of rectangular bars. Values of different series are stacked in multiple-series bars. Follow the steps below to create a stacked bar series:

Use the DxChart.Data property to specify an IEnumerable<T> data source.
Add a DxChartStackedBarSeries object to chart markup.
Use series ArgumentField and ValueField properties to specify data source fields that contain arguments and values for chart points.
Optional. Use the Stack property to create a side-by-side bar chart.
