Stacked Spline Area Chart

Expanded Short Description

The Stacked Spline Area Chart is represented by the StackedSplineAreaSeriesView object, which belongs to Area Series Views. This view is similar to Stacked Area Chart, but plots a fitted curve through each data point in a series.

A Stacked Spline Area chart is shown in the image below. Note that this chart type is based upon the XYDiagram, so it can be rotated to show areas either vertically or horizontally.

Note

If two stacked areas contain data points for different arguments, points for missing arguments are not treated as zero-value points.

A Stacked Spline 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.

Note that if a series contains data points with both positive and negative values, it is treated as a series with positive values, while all its negative values are treated as zeros.

Expanded Chart Type Characteristics

The table below lists the main characteristics of this chart type.

Feature

Value

Series View type StackedSplineAreaSeriesView
Diagram type 2D-XYDiagram
Number of arguments per series point 1
Number of values per series point 1
Note

For information on which chart types can be combined with the Stacked Spline Area Chart, refer to the Series Views Compatibility document.

Expanded Example

The following example demonstrates how to create a ChartControl with a series of the StackedSplineAreaSeriesView type, set its general properties, and add this chart to a form at runtime. Before proceeding with this example, first create a Windows Forms Application in Visual Studio, and include all necessary assemblies to the References list of your project.

Then, add the following code to the Form.Load event handler.
