The Full-Stacked Spline Area Chart (100% Stacked Spline Area Chart) is represented by the FullStackedSplineArea3DSeriesView object, which belongs to Area Series Views. This view is similar to Full-Stacked Area Chart, but plots a fitted curve through each data point in a series.
A Full-Stacked Spline Area chart is shown in the image below.
Note
A Full-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.
The table below lists the main characteristics of this chart type.
NoteFor information on which chart types can be combined with the Full-Stacked Spline Area Chart, refer to the Series Views Compatibility document.
The following example demonstrates how to create a ChartControl with two series of the FullStackedSplineArea3DSeriesView type, set their 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.
| C# |
using System;
using System.Windows.Forms;
using DevExpress.XtraCharts;
private void Form1_Load(object sender, EventArgs e) {
ChartControl fullStackedSplineArea3DChart = new ChartControl();
Series series1 = new Series("Series 1", ViewType.FullStackedSplineArea3D);
Series series2 = new Series("Series 2", ViewType.FullStackedSplineArea3D);
series1.Points.Add(new SeriesPoint("A", 80));
series1.Points.Add(new SeriesPoint("B", 20));
series1.Points.Add(new SeriesPoint("C", 50));
series1.Points.Add(new SeriesPoint("D", 30));
series2.Points.Add(new SeriesPoint("A", 40));
series2.Points.Add(new SeriesPoint("B", 60));
series2.Points.Add(new SeriesPoint("C", 20));
series2.Points.Add(new SeriesPoint("D", 80));
fullStackedSplineArea3DChart.Series.AddRange(new Series[] {
series1,
series2});
((FullStackedSplineArea3DSeriesView)series1.View).Transparency = 20;
((FullStackedSplineArea3DSeriesView)series2.View).Transparency = 60;
((XYDiagram3D)fullStackedSplineArea3DChart.Diagram).ZoomPercent = 110;
ChartTitle chartTitle1 = new ChartTitle();
chartTitle1.Text = "3D Full Stacked Spline Area Chart";
fullStackedSplineArea3DChart.Titles.Add(chartTitle1);
fullStackedSplineArea3DChart.Legend.Visible = false;
fullStackedSplineArea3DChart.Dock = DockStyle.Fill;
this.Controls.Add(fullStackedSplineArea3DChart);
}
