PieChart series are not centered on iOS

[Alexei]

Hi Telerik team!

Trying to display a simple chart. It works fine in Android, but in iOS it looks like series are not centered. (screen attached)

Could you please help with it?

<telerikChart:RadPieChart Palette="{x:Static viewModels:BenefitsViewModel.CustomChartPalette}" BackgroundColor="Aqua"
                                                    RelativeLayout.XConstraint="{ConstraintExpression Type=RelativeToParent, Property=Width, Factor=0.5, Constant=-100}"
                                                    RelativeLayout.YConstraint="{ConstraintExpression Type=Constant, Constant=50}"
                                                    RelativeLayout.WidthConstraint="{ConstraintExpression Type=Constant, Constant=200}"
                                                    RelativeLayout.HeightConstraint="{ConstraintExpression Type=Constant, Constant=200}" Rotation="90">
                                              <telerikChart:RadPieChart.Series>
                                                <telerikChart:PieSeries ItemsSource="{Binding PieChartBenefitsData}" AllowSelect="False" ShowLabels="False" >
                                                  <telerikChart:PieSeries.ValueBinding>
                                                    <telerikChart:PropertyNameDataPointBinding PropertyName="Value"/>
                                                  </telerikChart:PieSeries.ValueBinding>
                                                </telerikChart:PieSeries>
                                              </telerikChart:RadPieChart.Series>
                                            </telerikChart:RadPieChart>

Hello Alexei,

I can confirm the issue from our side. We will address it in our next official release (due in the mid September).

Meanwhile I can suggest the following workaround:

 - define custom renderer in ios project:

public class CustomChartRenderer : PieChartRenderer
   {
       protected override void OnElementChanged(ElementChangedEventArgs<RadPieChart> e)
       {
           base.OnElementChanged(e);
           this.Control.Insets = new UIKit.UIEdgeInsets(10, 10, 10, 10);
       }
   }

- Set it as renderer for the pie chart:

[assembly: Xamarin.Forms.ExportRenderer(typeof(Telerik.XamarinForms.Chart.RadPieChart), typeof(CustomChartRenderer))]

Please excuse us for the inconvenience caused.

Regards,
Tsvyatko
