Full-Stacked Bar Chart

Short Description

The Full-Stacked Bar Chart (100%-Stacked Bar Chart) is represented by the FullStackedBarSeriesView object, which belongs to Bar and Column Series Views. This view displays all series stacked, with a single bar for each category. The height of each bar is always the full height of the chart diagram (i.e. 1). The series values are displayed as percentages of each bar.

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

Note

A Full-Stacked Bar chart can display series containing data points with positive or negative values. A series with positive values, however, 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.

Chart Type Characteristics

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

Feature	Value
Series View type	FullStackedBarSeriesView
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 Full-Stacked Bar Chart, refer to the Combining Different Series Views document.

Example

The following example demonstrates how to create a ChartControl with two series of the FullStackedBarSeriesView type, and add this chart to a form at runtime. Before proceeding with this example, create a Windows Forms Application in Visual Studio, and add all required assemblies to the References list of your project.

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

C#

using DevExpress.XtraCharts;
// ...

private void Form1_Load(object sender, EventArgs e) {
    // Create a new chart.
    ChartControl FullStackedBarChart = new ChartControl();

    // Create two full-stacked bar series.
    Series series1 = new Series("Series 1", ViewType.FullStackedBar);
    Series series2 = new Series("Series 2", ViewType.FullStackedBar);

    // Add points to them.
    series1.Points.Add(new SeriesPoint(1, 10));
    series1.Points.Add(new SeriesPoint(2, 12));
    series1.Points.Add(new SeriesPoint(3, 14));
    series1.Points.Add(new SeriesPoint(4, 17));

    series2.Points.Add(new SeriesPoint(1, 15));
    series2.Points.Add(new SeriesPoint(2, 18));
    series2.Points.Add(new SeriesPoint(3, 25));
    series2.Points.Add(new SeriesPoint(4, 33));

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

    // Set the numerical argument scale types for the series,
    // as it is qualitative, by default.
    series1.ArgumentScaleType = ScaleType.Numerical;
    series2.ArgumentScaleType = ScaleType.Numerical;

    // Access the view-type-specific options of the series.
    ((FullStackedBarSeriesView)series1.View).BarWidth = 0.4;

    // Access the type-specific options of the diagram.
    ((XYDiagram)FullStackedBarChart.Diagram).EnableAxisXZooming = true;

    // Hide the legend (if necessary).
    FullStackedBarChart.Legend.Visible = false;

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

VB.NET

Imports DevExpress.XtraCharts
' ...

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) _
Handles MyBase.Load
    ' Create a new chart.
    Dim FullStackedBarChart As New ChartControl()

    ' Create two full-stacked bar series.
    Dim series1 As New Series("Series 1", ViewType.FullStackedBar)
    Dim series2 As New Series("Series 2", ViewType.FullStackedBar)

    ' Add points to them.
    series1.Points.Add(New SeriesPoint(1, 10))
    series1.Points.Add(New SeriesPoint(2, 12))
    series1.Points.Add(New SeriesPoint(3, 14))
    series1.Points.Add(New SeriesPoint(4, 17))

    series2.Points.Add(New SeriesPoint(1, 15))
    series2.Points.Add(New SeriesPoint(2, 18))
    series2.Points.Add(New SeriesPoint(3, 25))
    series2.Points.Add(New SeriesPoint(4, 33))

    ' Add both series to the chart.
    FullStackedBarChart.Series.AddRange(New Series() { series1, series2 })

    ' Set the numerical argument scale types for the series,
    ' as it is qualitative, by default.
    series1.ArgumentScaleType = ScaleType.Numerical
    series2.ArgumentScaleType = ScaleType.Numerical

    ' Access the view-type-specific options of the series.
    CType(series1.View, FullStackedBarSeriesView).BarWidth = 0.4

    ' Access the type-specific options of the diagram.
    CType(FullStackedBarChart.Diagram, XYDiagram).EnableAxisXZooming = True

    ' Hide the legend (if necessary).
    FullStackedBarChart.Legend.Visible = False

    ' Add the chart to the form.
    FullStackedBarChart.Dock = DockStyle.Fill
    Me.Controls.Add(FullStackedBarChart)
End Sub
