About Stacked Spline Charts

The icon used to represent this chart type in the ChartType drop-down in Visual Studio's properties window.

A stacked line chart is a line chart in which lines do not intersect, because they are cumulative at each point. In a stacked 100% line chart, the lines reach a total of 100% of the axis range at each point.

A stacked spline chart is different from a stacked line chart because it uses spline tension to connect points in each line.
