Example

The following example demonstrates how to create a ChartControl with two series of the SideBySideRangeBarSeriesView 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 DevExpress.XtraCharts;
using DevExpress.XtraEditors;
using System;
using System.Windows.Forms;
namespace RangeBarChart {
    public partial class Form1 : XtraForm {
        public Form1() {
            InitializeComponent();
        }
        private void Form1_Load(object sender, EventArgs e) {
            // Create a new chart.
            ChartControl rangeBarChart = new ChartControl();

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

            // Add points to them.
            series1.Points.Add(new SeriesPoint("A", 10, 15));
            series1.Points.Add(new SeriesPoint("B", 4, 7));
            series1.Points.Add(new SeriesPoint("C", 3, 13));
            series1.Points.Add(new SeriesPoint("D", 2, 11));
            series1.Points.Add(new SeriesPoint("E", 1, 8));

            series2.Points.Add(new SeriesPoint("A", 9, 13));
            series2.Points.Add(new SeriesPoint("B", 5, 10));
            series2.Points.Add(new SeriesPoint("C", 1, 9));
            series2.Points.Add(new SeriesPoint("D", 3, 7));
            series2.Points.Add(new SeriesPoint("E", 2, 10));

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

            // Specify series label options.
            series2.LabelsVisibility = DevExpress.Utils.DefaultBoolean.True;
            RangeBarSeriesLabel seriesLabel = (RangeBarSeriesLabel)series2.Label;
            seriesLabel.Position = RangeBarLabelPosition.Outside;
            seriesLabel.Kind = RangeBarLabelKind.TwoLabels;
            seriesLabel.Indent = 10;

            // Access the view-type-specific options of the series.
            SideBySideRangeBarSeriesView myView1 = (SideBySideRangeBarSeriesView)series1.View;
            myView1.MaxValueMarkerVisibility = DevExpress.Utils.DefaultBoolean.True;
            myView1.MinValueMarkerVisibility = DevExpress.Utils.DefaultBoolean.True;
            myView1.MinValueMarker.Kind = MarkerKind.Circle;
            myView1.MaxValueMarker.Kind = MarkerKind.Star;
            myView1.MaxValueMarker.StarPointCount = 5;
            ((SideBySideRangeBarSeriesView)series2.View).BarWidth = 0.4;

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

            // Hide the legend (if necessary).
            rangeBarChart.Legend.Visibility = DevExpress.Utils.DefaultBoolean.True;

            // Add a title to the chart (if necessary).
            rangeBarChart.Titles.Add(new ChartTitle());
            rangeBarChart.Titles[0].Text = "A Side-by-Side Range Bar Chart";
            rangeBarChart.Titles[0].WordWrap = true;

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