The Stacked Area series displays data as areas on a diagram, so that the value of each data point is aggregated with the underlying data points’ values. This representation is useful when it is necessary to compare both the point values and their aggregate for the same point arguments.
An example of the Stacked Area chart is shown in the image below.
Note
If two stacked areas contain data points for different arguments, points for missing arguments are not treated as zero-value points.
A Stacked Area chart can display series containing data points with positive or negative values. However, a series with positive values is stacked only with other series containing positive values; and a series with negative values is stacked with other series containing negative values.
The table below lists the main characteristics of this chart type.
| Feature | Value |
|---|---|
| Series View type | AreaStackedSeries2D |
| Diagram type | XYDiagram2D |
| Number of arguments per series point | 1 |
| Number of values per series point | 1 |
For information on which series view types can be combined with the Stacked Area view, refer to the Series Type Compatibility document.
The following example demonstrates how to create a 2D Stacked Area chart.
