The Full-Stacked Bar Chart (100%-Stacked Bar Chart) is represented by the FullStackedBarSeriesView object, which belongs to Bar 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, and 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. However, positive values are stacked only with other positive values; and negative values are stacked with other negative values.
The table below lists the main characteristics of this chart type.
Note
For information on which chart types can be combined with the Full-Stacked Bar Chart, refer to the Series Views Compatibility document.
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) {
ChartControl FullStackedBarChart = new ChartControl();
Series series1 = new Series("Series 1", ViewType.FullStackedBar);
Series series2 = new Series("Series 2", ViewType.FullStackedBar);
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));
FullStackedBarChart.Series.AddRange(new Series[] { series1, series2 });
series1.ArgumentScaleType = ScaleType.Numerical;
series2.ArgumentScaleType = ScaleType.Numerical;
((FullStackedBarSeriesView)series1.View).BarWidth = 0.4;
((XYDiagram)FullStackedBarChart.Diagram).EnableAxisXZooming = true;
FullStackedBarChart.Legend.Visible = false;
FullStackedBarChart.Dock = DockStyle.Fill;
this.Controls.Add(FullStackedBarChart);
}
