InnerRadius has no effect on the position of DataLabels

[Belitharian]

Describe the bug
The InnerRadius attribute no longer has any effect on the position of DataLabels when DataLabelsPosition is set.

To Reproduce
Steps to reproduce the behavior:

• Create a new WPF application ;
• Create a new ViewModel :

public class ViewModel
{
    public ISeries[] Series { get; set; }
        = new ISeries[]
        {
            new PieSeries<double>
            {
                Values = new double[] { 2 },
                Stroke = new SolidColorPaint(SKColors.White, 2),
                Fill = new SolidColorPaint(SKColors.Aqua),
                DataLabelsPaint = new SolidColorPaint(SKColors.Black),
                InnerRadius = 160,
                DataLabelsSize = 24,
                DataLabelsPosition = LiveChartsCore.Measure.PolarLabelsPosition.Middle,
            },
            new PieSeries<double>
            {
                Values = new double[] { 6 },
                Fill = new SolidColorPaint(SKColors.GreenYellow),
                Stroke = new SolidColorPaint(SKColors.White, 2),
                DataLabelsPaint = new SolidColorPaint(SKColors.Black),
                InnerRadius = 160,
                DataLabelsSize = 24,
                DataLabelsPosition = LiveChartsCore.Measure.PolarLabelsPosition.Middle,
            },
            new PieSeries<double>
            {
                Values = new double[] { 8 },
                Stroke = new SolidColorPaint(SKColors.White, 2),
                Fill = new SolidColorPaint(SKColors.Magenta),
                DataLabelsPaint = new SolidColorPaint(SKColors.Black),
                InnerRadius = 160,
                DataLabelsSize = 24,
                DataLabelsPosition = LiveChartsCore.Measure.PolarLabelsPosition.Middle,
            }
        };
}

• Create the UI :

<Window
    x:Class="WpfApp1.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="clr-namespace:WpfApp1"
    xmlns:lvc="clr-namespace:LiveChartsCore.SkiaSharpView.WPF;assembly=LiveChartsCore.SkiaSharpView.WPF"
    Width="960"
    Height="540"
    Background="#FF0A0A10">

    <Window.DataContext>
        <local:ViewModel />
    </Window.DataContext>

    <Grid Margin="45">
        <lvc:PieChart x:Name="PieChart" Series="{Binding Series}" />
    </Grid>

</Window>

• Observe the DataLabels position.

Expected behavior
The DataLabels should be in the position : middle, start, outer, end ; according to what the developer decided.
Only the Measure.PolarLabelsPosition.ChartCenter position works.

Screenshots
With InnerRadius set :

Without InnerRadius set :

That's my first bug report, hope this helps! 👍

I'm not quite sure if I understand that issue correctly but in general I would not expect that the labels move automatically if I change the inner radius of a pie chart. The postions of DataLabels should be handled separately. However, this might be a side-effect of the fix for #771.

This is already fixed in beta.900 thanks for the report.
