The following members return DrawOptions objects:
Remarks
The DrawOptions class serves as a base for objects that are passed to the ChartControl.CustomDrawSeries and ChartControl.CustomDrawSeriesPoint events via the CustomDrawSeriesEventArgsBase.SeriesDrawOptions property and contain appropriate drawing settings which are specific to the view type of the currently drawn series.
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.
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;
}
