Asked On August 30, 2019 10:12 AM UTC

Hi, I develop cross-platform App using sfchart and sometimes I get zero (0) value data (of course from my db) to bind into pie chart. after activate smartlabel (EnableSmartLabels="true" ), all data, including zero value  also appear on chart. My question is, any suggestion to hide zero value in label?
(I attached the picture of chart)

Thank you

Hi Ronanobelta Syakura, 
 
Greetings from Syncfusion. 
 
Query: How to hide the 0 value from DataMarker Label. 
 
Your requirement can be achieved by excluding the zero value from the bound ItemsSource of PieSeries using Converter.  
 
Please have code examples, 
 
Chart XAML: 
 
<chart:PieSeries x:Name="pieSeries"
                            ItemsSource="{Binding Data,Converter={StaticResource ExcludeZeroConverter}}"
                             EnableSmartLabels = "true" 
                            XBindingPath="Name"
                            YBindingPath="Height">
                    <chart:PieSeries.DataMarker>
                        <chart:ChartDataMarker ShowLabel="True"/>
                    </chart:PieSeries.DataMarker>
                    </chart:PieSeries> 
 
 
ExcludeZeroConverter: 
 
 public class ExcludeZeroConverter : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
        {
            var collection = value as List<Person>;
            return collection != null ? collection.Where(x => x.Height != 0).ToList() : value;
        }

        .......
    } 
 
Here, Height is the YBindingPath property.  
 
Please download the attached sample from below link 
 
 
Thanks, 
Muneesh Kumar G
