How to add the icons on top of each column/bar segment in Xamarin.Forms Chart?

Platform: Xamarin.Forms |
Control: SfChart |

You can add icon at the top of each bar segment by setting DataTemplate for DataMarker with an IValueConverter to the LabelTemplate property.

The following code sample and output demonstrates how to add an icon at the top of each bar segment and you can download the complete sample here.

XAML:

<ResourceDictionary>           
            <local:ChartImageConverter x:Key="imageConverter"></local:ChartImageConverter>
            <DataTemplate x:Key="icon">
                    <Image x:Name="image" Source="{Binding YValue, Converter={StaticResource imageConverter}}" WidthRequest="20" HeightRequest="20"/>
            </DataTemplate>           
</ResourceDictionary>        
    ……
<chart:ColumnSeries ItemsSource="{Binding SeriesData}" XBindingPath="XValue" YBindingPath="YValue">
                <chart:ColumnSeries.DataMarker>
                    <chart:ChartDataMarker ShowLabel="True" LabelTemplate="{StaticResource icon}">
                        <chart:ChartDataMarker.LabelStyle>
                            <chart:DataMarkerLabelStyle LabelPosition="Inner"/>
                        </chart:ChartDataMarker.LabelStyle>
                    </chart:ChartDataMarker>
                </chart:ColumnSeries.DataMarker>
</chart:ColumnSeries>

C#:

public class ChartImageConverter : IValueConverter
{
        public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            if (System.Convert.ToDouble(value) < 0)
                return "Down.png";
            else
                return "Up.png";
        }
 
        public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            return value;
        }
}

Output:

Chart with icons placed on top of it's bar segments in Xamarin.Forms
