PointDrawOptionsBase Class

Represents the base class for objects which define drawing options for point, line and area charts.

Assembly: DevExpress.XtraCharts.v24.1.dll

Declaration

C#
VB.NET

public class PointDrawOptionsBase :
    DrawOptions

Public Class PointDrawOptionsBase
    Inherits DrawOptions

Remarks

The PointDrawOptionsBase class introduces the PointDrawOptionsBase.Marker and PointDrawOptionsBase.Shadow properties, which can be useful to customize the appearance of series of the point, line and area types.

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#
VB.NET

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;
}

Imports DevExpress.XtraCharts

Private Sub OnCustomDrawSeries(sender As Object, e As CustomDrawSeriesEventArgs) _

   ' Find all Bar Series by their view type, and fill them with Aqua color.

   End If

   ' Find all Point Series by the type of its DrawOptions, 
   ' and change their marker kind to diamond.
