SideBySideBarSeriesView.BarDistanceFixed Property

Gets or sets the fixed distance value (in pixels) between two bars of different series shown at the same argument point.

Namespace: DevExpress.XtraCharts

Assembly: DevExpress.XtraCharts.v20.1.dll

Declaration

[XtraChartsLocalizableCategory(XtraChartsCategory.Layout)]
public int BarDistanceFixed { get; set; }
<XtraChartsLocalizableCategory(XtraChartsCategory.Layout)>
Public Property BarDistanceFixed As Integer

Property Value

Type Description
Int32

An integer value that represents the distance between two neighboring bars, in pixels.

Remarks

The BarDistanceFixed property specifies the distance between two bars in a Side-by-Side Bar series. This property's value is measured in pixels, and doesn't depend on the size of a Chart.

To specify the distance between two bars as a fraction of axis units, use the SideBySideBarSeriesView.BarDistance property. If both the BarDistanceFixed and SideBySideBarSeriesView.BarDistance properties are in effect at the same time, their values are combined together as constant and variable distances.

NOTE

The BarDistanceFixed property is synchronized in all Side-by-Side Bar Series which are present in a ChartControl, and all of them always return the same value. If you change the distance between two bars for one Side-by-Side Bar series view, it will affect the BarDistanceFixed property in all other Side-by-Side Bar series views.

For the same reason, when trying to set the BarDistanceFixed property before a Series is added to a chart's collection, an ArgumentException is thrown.

Examples

This example demonstrates how to create a ChartControl with two series of the SideBySideBarSeriesView type at runtime:

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;
        }
    }
