Stacked Bar Chart

Short Description

The Stacked Bar Chart is represented by the StackedBar3DSeriesView object, which belongs to Bar Series Views. This view displays all points from different series, but with the same argument, stacked in a single bar (for instance, this is useful to show that each bar represents a particular 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

A Stacked Bar 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.

Chart Type Characteristics

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

Feature	Value
Series View type	StackedBar3DSeriesView
Diagram type	XYDiagram3D
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 StackedBar3DSeriesView 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#
VB.NET

csharp

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

private void Form1_Load(object sender, EventArgs e) {
    // Create a new chart.
    ChartControl stackedBar3DChart = new ChartControl();

    // Create two series of the StackedBar3D view type.
    Series series1 = new Series("Series 1", ViewType.StackedBar3D);
    Series series2 = new Series("Series 2", ViewType.StackedBar3D);

    // 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.
    stackedBar3DChart.Series.AddRange(new Series[] {
        series1,
        series2});

    // Adjust the view-type-specific options of the first series.
    StackedBar3DSeriesView myView = (StackedBar3DSeriesView)series1.View;
    myView.BarDepthAuto = false;
    myView.BarDepth = 1.5;
    myView.BarWidth = 1;
    myView.Transparency = 160;
    myView.Model = Bar3DModel.Cylinder;
    myView.ShowFacet = false;

    // Access the diagram's options.
    ((XYDiagram3D)stackedBar3DChart.Diagram).ZoomPercent = 110;

    // Add a title to the chart and hide the legend.
    ChartTitle chartTitle1 = new ChartTitle();
    chartTitle1.Text = "3D Stacked Bar Chart";
    stackedBar3DChart.Titles.Add(chartTitle1);
    stackedBar3DChart.Legend.Visible = false;

    // Add the chart to the form.
    stackedBar3DChart.Dock = DockStyle.Fill;
    this.Controls.Add(stackedBar3DChart);
}
