Full-Stacked Spline Area Chart

  • 3 minutes to read

Short Description

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 the 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 that contain data points with positive or negative values. A series with positive values, however, is stacked only with other series that contain positive values; and a series with negative values is stacked with series that contain 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.

Chart Type Characteristics

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

Feature Value
Series View type FullStackedSplineArea3DSeriesView
Diagram type XYDiagram3D
Number of arguments per series point 1
Number of values per series point 1

Example

The following example creates a ChartControl with two series of the FullStackedSplineArea3DSeriesView type, sets their general properties, and adds this chart to a form at runtime. Before proceeding with this example, first create a Windows Forms Application in Visual Studio, and add all required assemblies to the project’s References list.

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

using System;
using System.Windows.Forms;
using DevExpress.XtraCharts;
// ...

private void Form1_Load(object sender, EventArgs e) {
    // Create an empty chart.
    ChartControl fullStackedSplineArea3DChart = new ChartControl();

    // Create two series of the FullStackedSplineArea3D view type.
    Series series1 = new Series("Series 1", ViewType.FullStackedSplineArea3D);
    Series series2 = new Series("Series 2", ViewType.FullStackedSplineArea3D);

    // Populate both series with points.
    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));

    // Add the series to the chart.
    fullStackedSplineArea3DChart.Series.AddRange(new Series[] {
        series1,
        series2});

    // Adjust the view-type-specific options of the series.
    ((FullStackedSplineArea3DSeriesView)series1.View).Transparency = 20;
    ((FullStackedSplineArea3DSeriesView)series2.View).Transparency = 60;

    // Access the diagram's options.
    ((XYDiagram3D)fullStackedSplineArea3DChart.Diagram).ZoomPercent = 110;

    // Add a title to the chart and hide the legend.
    ChartTitle chartTitle1 = new ChartTitle();
    chartTitle1.Text = "3D Full Stacked Spline Area Chart";
    fullStackedSplineArea3DChart.Titles.Add(chartTitle1);
    fullStackedSplineArea3DChart.Legend.Visible = false;

    // Add the chart to the form.
    fullStackedSplineArea3DChart.Dock = DockStyle.Fill;
    this.Controls.Add(fullStackedSplineArea3DChart);
}
