Example
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;
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];
}
The following API members configure the histogram options:
