Example

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

C#

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;
    chartControl1.Series.Add(series);
    // 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();
    xmlDataSet.ReadXml(fileName);
    return xmlDataSet.Tables[tableName];
}

VB.NET

Private Sub Form1_Load(ByVal sender As Object, ByVal e As EventArgs)
    ' Load data to a chart.
    chartControl1.DataSource = LoadDataTableFromXml("..\..\Data\CityWeather.xml", "CityWeather")
    Dim series As Series = New Series()
    series.ArgumentDataMember = "Temperature"
    Dim view As SideBySideBarSeriesView = TryCast(series.View, SideBySideBarSeriesView)
    view.Border.Visibility = DevExpress.Utils.DefaultBoolean.[True]
    view.BarWidth = 1
    chartControl1.Series.Add(series)
    ' Configure histogram options.
    Dim diagram As XYDiagram = TryCast(chartControl1.Diagram, XYDiagram)
    Dim scaleOptions As NumericScaleOptions = 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
End Sub

Private Shared Function LoadDataTableFromXml(ByVal fileName As String, ByVal tableName As String) As DataTable
    Dim xmlDataSet As DataSet = New DataSet()
    xmlDataSet.ReadXml(fileName)
    Return xmlDataSet.Tables(tableName)
End Function

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.
