Side-by-Side Stacked Bar
The Side-by-Side Stacked Bar series combines the advantages of both the Stacked Bar and Side-by-Side Bar chart types, so that you can stack different bars, and combine them into groups shown side-by-side across the same axis value (via the SideBySideStackedBarSeriesView.StackedGroup property).
An example of the Side-by-Side Stacked Bar chart is shown in the image below.
