Contact Syncfusion support.

Support Response - SyncFusion You can achieve this by setting a DataTemplate with an IValueConverter to the data-marker marker and using the ChartDataMarker.LabelTemplate property. See the following code snippet for more details.

DateTemplate

< ResourceDictionary >    
 < local: DataMarkerConverter x: Key = " labelConverter " > </ local: DataMarkerConverter >     
  < DataTemplate x: Key = " LabelTemplate " >     
    < StackLayout >    
        < Label Text = " {Binding YValue, Converter = {StaticResource labelConverter} " />     
    </ StackLayout >    
  </ DataTemplate >    
</ ResourceDictionary >

Converter

public class DataMarkerConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        double yValue = System.Convert.ToDouble(value);
        return yValue.ToString("#,###.##", new CultureInfo("pt-BR"));
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        return value;
    }
}
