Remarks

The GanttDrawOptions class contains specific settings which can be used to custom draw series of the Gantt type.

Example

This example demonstrates how to implement custom drawing in charts when drawing its series. To do this you should handle the ChartControl.CustomDrawSeries event, and then you’re able to change some drawing parameters using its event args.

Note

For the WebChartControl you should handle its WebChartControl.CustomDrawSeries event to implement this task.

C#

using DevExpress.XtraCharts;
// ...

private void chartControl1_CustomDrawSeries(object sender, 
CustomDrawSeriesEventArgs e) {
   // Find all Bar Series by their view type,
   // and fill them with Aqua color.
   if (e.Series.View is BarSeriesView)
      e.SeriesDrawOptions.Color = Color.Aqua;

   // Find the series by its name, 
   // and change its line style to dash-dot-dot.
   // (Here it's assumed that the series view type is LineSeriesView).
   if (e.Series.Name == "Line Series") 
      ((LineDrawOptions)e.SeriesDrawOptions).LineStyle.DashStyle = 
      DashStyle.DashDotDot;

   // Find all Point Series by the type of its DrawOptions, 
   // and change their marker kind to diamond.
   if (e.SeriesDrawOptions.GetType() == typeof(PointDrawOptions)) 
      ((PointDrawOptions)e.SeriesDrawOptions).Marker.Kind = 
      MarkerKind.Diamond;
}

VB.NET

Imports DevExpress.XtraCharts
' ...

Private Sub OnCustomDrawSeries(sender As Object, e As CustomDrawSeriesEventArgs) _
Handles ChartControl1.CustomDrawSeries
   ' Find all Bar Series by their view type, and fill them with Aqua color.
   If TypeOf e.Series.View Is BarSeriesView Then
      e.SeriesDrawOptions.Color = Color.Aqua
   End If

   ' Find the series by its name, and change its line style to dash-dot-dot.
   ' (Here it's assumed that the series view type is LineSeriesView).
   If e.Series.Name = "Line Series" Then
      CType(e.SeriesDrawOptions, LineDrawOptions).LineStyle.DashStyle = DashStyle.DashDotDot
   End If

   ' Find all Point Series by the type of its DrawOptions, 
   ' and change their marker kind to diamond.
   If e.SeriesDrawOptions.GetType() Is GetType(PointDrawOptions) Then
      CType(e.SeriesDrawOptions, PointDrawOptions).Marker.Kind = MarkerKind.Diamond
   End If
End Sub
