Used to customize the empty points which are NaN data points.

Inheritance
System.Object
EmptyPointSettings
Namespace: Syncfusion.Maui.Toolkit.Charts
Assembly: Syncfusion.Maui.Toolkit.dll
Syntax
public class EmptyPointSettings : Element
Remarks

By customizing these empty points, the positions of the data points are highlighted, thereby improving data visualization.

EmptyPointSettings class provides properties to customize these empty points by modifying attributes such as Fill, Stroke, and StrokeWidth.

To customize empty points, create an instance of EmptyPointSettings, configure it as needed, and then add it to the series.

EmptyPointSettings is not supported for all area-related series, as well as for FastChart and ErrorBarSeries.
