Short Description

The Stacked Bar Chart is represented by the StackedBarSeriesView object, which belongs to Bar Series Views. This view displays all the points of its series. Series values are stacked at arguments included in multiple series. So, the height of each bar is determined by the total of all the series values for the category. So, the height of each bar is determined by the total of all the series values for the category.

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

Chart Type Characteristics

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

Feature	Value
Series View type	StackedBarSeriesView
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 Bar Chart, refer to the Series Views Compatibility document.

Example

The following example demonstrates how to create a ChartControl with two series of the StackedBarSeriesView type, 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) {
    // Create a new chart.
    ChartControl stackedBarChart = new ChartControl();

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

    // Add points to them
    series1.Points.Add(new SeriesPoint("A", 10));
    series1.Points.Add(new SeriesPoint("B", 12));
    series1.Points.Add(new SeriesPoint("C", 14));
    series1.Points.Add(new SeriesPoint("D", 17));

    series2.Points.Add(new SeriesPoint("A", 15));
    series2.Points.Add(new SeriesPoint("B", 18));
    series2.Points.Add(new SeriesPoint("C", 25));
    series2.Points.Add(new SeriesPoint("D", 33));

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

    // Access the view-type-specific options of the series.
    ((StackedBarSeriesView)series1.View).BarWidth = 0.8;

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

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

    // Add a title to the chart (if necessary).
    stackedBarChart.Titles.Add(new ChartTitle());
    stackedBarChart.Titles[0].Text = "A Stacked Bar Chart";

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

VB.NET

    series2.Points.Add(New SeriesPoint("A", 15))
    series2.Points.Add(New SeriesPoint("B", 18))
    series2.Points.Add(New SeriesPoint("C", 25))
    series2.Points.Add(New SeriesPoint("D", 33))

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

    ' Access the view-type-specific options of the series.
    CType(series1.View, StackedBarSeriesView).BarWidth = 0.8

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

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

    stackedBarChart.Titles.Add(New ChartTitle())
    stackedBarChart.Titles(0).Text = "A Stacked Bar Chart"

    ' Add the chart to the form.
    stackedBarChart.Dock = DockStyle.Fill
    Me.Controls.Add(stackedBarChart)
