This example demonstrates how to create a histogram chart with a given number of bins.

private void Form1_Load(object sender, EventArgs e) {
    // Load data to a chart.
    chartControl1.DataSource = LoadDataTableFromXml("..\\..\\Data\\CityWeather.xml", "CityWeather");
    Series series = new Series();
    series.ArgumentDataMember = "Temperature";
    SideBySideBarSeriesView view = series.View as SideBySideBarSeriesView;
    view.Border.Visibility = DevExpress.Utils.DefaultBoolean.True;
    view.BarWidth = 1;
    // Configure histogram options.
    XYDiagram diagram = chartControl1.Diagram as XYDiagram;
    NumericScaleOptions scaleOptions = diagram.AxisX.NumericScaleOptions;
    scaleOptions.AggregateFunction = AggregateFunction.Histogram;
    scaleOptions.ScaleMode = ScaleMode.Interval;
    scaleOptions.IntervalOptions.DivisionMode = IntervalDivisionMode.Count;
    scaleOptions.IntervalOptions.Count = 5;
    scaleOptions.IntervalOptions.GridLayoutMode = GridLayoutMode.GridAndLabelShifted;
    diagram.AxisX.Label.TextPattern = "{A:F0}°C";
    diagram.AxisX.GridLines.Visible = true;    
static DataTable LoadDataTableFromXml(string fileName, string tableName) {
    DataSet xmlDataSet = new DataSet();
    return xmlDataSet.Tables[tableName];

The following API members configure the histogram options:

Member Description
ScaleGridOptionsBase.AggregateFunction Gets or sets the value indicating the aggregate function that should be used to relieve data.
ScaleOptionsBase.ScaleMode Gets or sets the scale mode for an axis.
NumericScaleOptions.IntervalOptions Stores options for numeric axis when its ScaleMode is Interval.
NumericIntervalOptions.DivisionMode Specifies how to divide axis scale into intervals.
NumericIntervalOptions.Count Gets or sets the number of intervals when DivisionMode is Count.
NumericIntervalOptions.GridLayoutMode Gets or sets the value that specifies the alignment of grid lines, major tickmarks and axis labels.
