Hi
Here’s my XAML:

                <s:SciChartDonutSurface ChartTitle="Times Distribution" ItemsSource="{Binding TimeGroups}">
                    <s:SciChartDonutSurface.ItemTemplate>
                        <DataTemplate DataType="s">
                            <s:DonutSegment SegmentValue="{Binding Path=Duration}" Text="{Binding Path=Name}"/>
                        </DataTemplate>
                    </s:SciChartDonutSurface.ItemTemplate>
                </s:SciChartDonutSurface>

And I have correctly created ObservableItems named TimeGroups, with properties Duration and Name.

I’m not seeing a thing…

What am I doing wrong?

Hi there,

Your ItemsSource collection should be of IPieSegmentViewModel type:

public ObservableCollection<IPieSegmentViewModel> TimeGroups { get; set; }

Also I see in your xaml code that you wrote your DataTemplate of DataType”s” maybe it can be the reason of the issue.

We have the documentation for SciChartDonutSurface here https://www.scichart.com/documentation/v4.x/webframe.html#The%20Donut%20Chart%20Type.html

And example of how to use it here https://www.scichart.com/example/wpf-chart-donut-chart-example/
