ChartControl.Series Property

Provides access to the chart control's collection of series objects.

Namespace: DevExpress.XtraCharts

Assembly: DevExpress.XtraCharts.v20.1.UI.dll

Declaration

public SeriesCollection Series { get; }
Public ReadOnly Property Series As SeriesCollection

Property Value

Type Description
SeriesCollection

The collection of series that the Chart Control displays.

Remarks

The Series property provides access to a collection of all series that the Chart Control displays. The property manages (adds, removes, accesses using indexer notation, etc.) chart's series that the Series class objects represent.

Note that series which are bound to data at the level of a chart control (in particular, using the ChartControl.DataSource, ChartControl.SeriesDataMember and both the SeriesBase.ArgumentDataMember and SeriesBase.ValueDataMembers properties) are created dynamically based upon the data obtained from the specified data source and they are not presented within the Series collection. In order to access such series use the CustomDrawSeriesEventArgsBase.Series property of a chart control's specific events (such as the ChartControl.CustomDrawSeries or ChartControl.CustomDrawSeriesPoint event, for instance). To perform a centralized customization of such series use the settings which are available via the ChartControl.SeriesTemplate property.

Examples

This example demonstrates how to create a ChartControl with two series of the SideBySideBarSeriesView type and bind them to a data source:

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

namespace SideBySideBar2D {
    public partial class Form1 : Form {
        public Form1() {
            InitializeComponent();
        }
        private void Form1_Load(object sender, EventArgs e) {
            // Create an empty chart.
            ChartControl chart = new ChartControl();

            // Bind a chart to a data source.
            chart.DataSource = DataPoint.GetDataPoints();

            // Create the first series and specify its data members.
            Series series1 = new Series("2018", ViewType.Bar);
            series1.ArgumentDataMember = "Region";
            series1.ValueDataMembers.AddRange("Value1");

            // Create the second series and specify its data members.
            Series series2 = new Series("2019", ViewType.Bar);
            series2.ArgumentDataMember = "Region";
            series2.ValueDataMembers.AddRange("Value2");

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

            // Change the first series's view settings.
            SideBySideBarSeriesView view1 = series1.View as SideBySideBarSeriesView;
            // The BarDistance, BarDistanceFixed, and EqualBarWidth property values are synchronized 
            // in all Side-by-Side Bar Series in a ChartControl.
            // So, you can specify them only for one series view.
            view1.BarDistance = 0.1;
            view1.BarDistanceFixed = 2;
            view1.BarWidth = 0.4;
            view1.EqualBarWidth = true;
            view1.Color = Color.MediumSeaGreen;

            // Change the second series's view settings.
            SideBySideBarSeriesView view2 = series2.View as SideBySideBarSeriesView;
            view2.BarWidth = 0.4;
            view2.Color = Color.MediumVioletRed;

            // Change the legend position.
            chart.Legend.AlignmentHorizontal = LegendAlignmentHorizontal.Right;
            chart.Legend.AlignmentVertical = LegendAlignmentVertical.Bottom;

            // Rotate the diagram.
            ((XYDiagram)chart.Diagram).Rotated = true;

            // Configure the x-axis appearance.
            ((XYDiagram)chart.Diagram).AxisX.Tickmarks.MinorVisible = false;
            ((XYDiagram)chart.Diagram).AxisX.Reverse = true;

            // Add a title to the chart.
            ChartTitle chartTitle1 = new ChartTitle();
            chartTitle1.Text = "Sales by Region";
            chart.Titles.Add(chartTitle1);

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

    public class DataPoint {
        public string Region { get; set; }
        public double Value1 { get; set; }
        public double Value2 { get; set; }
        public DataPoint(string region, double value1, double value2) {
            this.Region = region;
            this.Value1 = value1;
            this.Value2 = value2;
        }
        public static BindingList<DataPoint> GetDataPoints() {
            BindingList<DataPoint> data = new BindingList<DataPoint> {
                new DataPoint("Asia", 4.7685, 5.289),
                new DataPoint("Australia", 1.9576, 2.2727),
                new DataPoint("Europe", 3.0884, 3.7257),
                new DataPoint("North America", 3.7477, 4.1825),
                new DataPoint("South America", 1.8945, 2.1172),
            };
            return data;
        }
    }
}

The following example demonstrates how to create a ChartControl with two series of the SideBySideBarSeriesView 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.

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

namespace SideBySideBar2D {
    public partial class Form1 : Form {
        public Form1() {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e) {
            // Create an empty chart.
            ChartControl sideBySideBarChart = new ChartControl();

            // Create the first side-by-side bar series and add points to it.
            Series series1 = new Series("Side-by-Side Bar Series 1", ViewType.Bar);
            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));

            // Create the second side-by-side bar series and add points to it.
            Series series2 = new Series("Side-by-Side Bar Series 2", ViewType.Bar);
            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 the series to the chart.
            sideBySideBarChart.Series.Add(series1);
            sideBySideBarChart.Series.Add(series2);

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

            // Rotate the diagram (if necessary).
            ((XYDiagram)sideBySideBarChart.Diagram).Rotated = true;

            // Add a title to the chart (if necessary).
            ChartTitle chartTitle1 = new ChartTitle();
            chartTitle1.Text = "Side-by-Side Bar Chart";
            sideBySideBarChart.Titles.Add(chartTitle1);

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

    }
}
