    Series series = new Series("Gantt Series", ViewType.Gantt);
    series.ValueScaleType = ScaleType.DateTime;
    SeriesPointCollection points = series.Points;
    int index = points.AddGanttPoint(
      new TimeOnly(8, 0, 0),
      new DateTime(2023, 10, 20, 8, 0, 0),
      new DateTime(2023, 10, 25, 17, 0, 0)

    chartControl1.Series.Add(series);

    XYDiagram diagram = (XYDiagram)chartControl1.Diagram;
    diagram.AxisX.DateTimeScaleOptions.MeasureUnit = DateTimeMeasureUnit.Hour;
  }
}

VB.NET

Imports DevExpress.XtraCharts
Imports DevExpress.XtraEditors

Public Class MainForm
  Inherits XtraForm
  Public Sub New()
    Dim series As New Series("Gantt Series", ViewType.Gantt)
    series.ValueScaleType = ScaleType.DateTime
    Dim points As SeriesPointCollection = series.Points
    Dim index As Integer = points.AddGanttPoint(
      New TimeOnly(8, 0, 0),
      New DateTime(2023, 10, 20, 8, 0, 0),
      New DateTime(2023, 10, 25, 17, 0, 0)
    )
    chartControl1.Series.Add(series)

    Dim diagram As XYDiagram = CType(chartControl1.Diagram, XYDiagram)
    diagram.AxisX.DateTimeScaleOptions.MeasureUnit = DateTimeMeasureUnit.Hour
  End Sub
