yeah you're right on that actually, but it just gets read in at the start and it will never change

but that's the model right? I don't think it should notify anything even if it did

WPF CollectionView Filter on Property of Model?
I'm trying hard to find a proper solution, because this problem is actually nested one level more, as in: X has a list of Z, and I want to filter based on the name of Z and it should not show any Y's NOR X's that don't have a single X that don't have a single Z

WPF CollectionView Filter on Property of Model?
you told me it shouldn't happen in the SelectedY setter but I wouldn't know where else to put it, besides in some SelectionChanged event from the listbox

@Klarth so you are telling me to introduce a new observable list for the ListOfX from whatever Y that is selected in the viewmodel right? My question still remains as to where I should set that observablelist

WPF Framework Canvas Automatic Scaling based on largest coordinate in list
I fully managed to get it working using this code 
    public class ObjectComparisonConverter : IMultiValueConverter
    {
        public object Convert(object[] value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            return value[0].Equals(value[1]);
        }

        public object[] ConvertBack(object value, Type[] targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            throw new NotImplementedException();
        }
    }
    public class ObjectComparisonConverter : IMultiValueConverter
    {
        public object Convert(object[] value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            return value[0].Equals(value[1]);
        }

        public object[] ConvertBack(object value, Type[] targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            throw new NotImplementedException();
        }
    }
    public class CoordinateConverterSingle : IMultiValueConverter
    {
        public object Convert(object[] value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            double CanvasSize = (double)value[0];
            if (value.Length == 1) return CanvasSize / 2;
            double LargestCoordinate = (double)value[1];
            double CoordinateX = (double)value[2];

            //Scalefactor
            double ScaleFactor = (0.45 * CanvasSize);

            //Scale
            double result = CoordinateX / (LargestCoordinate / ScaleFactor);

            //Translate
            result += 0.5 * CanvasSize;

            return result;
        }

        public object[] ConvertBack(object value, Type[] targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            throw new NotImplementedException();
        }
    }

            if (value.Length == 1) return CanvasSize / 2;
            double LargestCoordinate = (double)value[1];
            double CoordinateX = (double)value[2];

            //Scalefactor
            double ScaleFactor = (0.45 * CanvasSize);

            //Scale
            double result = CoordinateX / (LargestCoordinate / ScaleFactor);

https://i.imgur.com/7Lr98Na.png it used to be able to find the old Ellipse element and get me the width and height, but it can't with EllipseGeometry?

Almost solved the issue myself, just need to figure out this next problem 
<Path Name="Center" Fill="Blue" Stroke="Black" StrokeThickness="2">
  <Path.Data>
      <EllipseGeometry RadiusX="8" RadiusY="8">
          <EllipseGeometry.Center>
              <MultiBinding Converter="{StaticResource CConverter}">
                  <Binding Path="Width" RelativeSource="{RelativeSource Mode=FindAncestor, AncestorType=Canvas}" Mode="OneWay" />
                  <Binding Path="Height" RelativeSource="{RelativeSource Mode=FindAncestor, AncestorType=Canvas}" Mode="OneWay" />
                  <Binding Path="RadiusX" RelativeSource="{RelativeSource Mode=FindAncestor, AncestorType=EllipseGeometry}" Mode="OneWay" />
                  <Binding Path="RadiusY" RelativeSource="{RelativeSource Mode=FindAncestor, AncestorType=EllipseGeometry}" Mode="OneWay" />
              </MultiBinding>
          </EllipseGeometry.Center>
      </EllipseGeometry>
  </Path.Data>
</Path>
<Path Name="Center" Fill="Blue" Stroke="Black" StrokeThickness="2">
  <Path.Data>
      <EllipseGeometry RadiusX="8" RadiusY="8">
          <EllipseGeometry.Center>
              <MultiBinding Converter="{StaticResource CConverter}">
                  <Binding Path="Width" RelativeSource="{RelativeSource Mode=FindAncestor, AncestorType=Canvas}" Mode="OneWay" />
                  <Binding Path="Height" RelativeSource="{RelativeSource Mode=FindAncestor, AncestorType=Canvas}" Mode="OneWay" />
                  <Binding Path="RadiusX" RelativeSource="{RelativeSource Mode=FindAncestor, AncestorType=EllipseGeometry}" Mode="OneWay" />
                  <Binding Path="RadiusY" RelativeSource="{RelativeSource Mode=FindAncestor, AncestorType=EllipseGeometry}" Mode="OneWay" />
              </MultiBinding>
          </EllipseGeometry.Center>
      </EllipseGeometry>
  </Path.Data>
</Path>
I don't know why this following code can't get find the property RadiusX on the EllipseGeometry https://i.imgur.com/izux1tM.png 
<Binding Path="RadiusX" RelativeSource="{RelativeSource Mode=FindAncestor, AncestorType=EllipseGeometry}" Mode="OneWay" />
<Binding Path="RadiusX" RelativeSource="{RelativeSource Mode=FindAncestor, AncestorType=EllipseGeometry}" Mode="OneWay" />

If there is a better way without Canvas or using a different method, feel free to chime in. I have also tried ViewBox but haven't gotten that one to work as well as the solution I posted above. 
<Viewbox Width="494" Height="494" RenderTransform="1 0 0 -1 0 0">
    <ItemsControl ItemsSource="{Binding ListOfX}">
        <ItemsControl.ItemTemplate>
            <DataTemplate>
                <Ellipse Width="8" Height="8" Fill="Red" Stroke="Black" StrokeThickness="2">
                    <Ellipse.RenderTransform>
                        <TranslateTransform X="{c:Binding --Calculation Here--}" Y="{c:Binding --Calculation Here--}" />
                    </Ellipse.RenderTransform>
                </Ellipse>
            </DataTemplate>
        </ItemsControl.ItemTemplate>
    </ItemsControl>
</Viewbox>
<Viewbox Width="494" Height="494" RenderTransform="1 0 0 -1 0 0">
    <ItemsControl ItemsSource="{Binding ListOfX}">
        <ItemsControl.ItemTemplate>
            <DataTemplate>
                <Ellipse Width="8" Height="8" Fill="Red" Stroke="Black" StrokeThickness="2">
                    <Ellipse.RenderTransform>
                        <TranslateTransform X="{c:Binding --Calculation Here--}" Y="{c:Binding --Calculation Here--}" />
                    </Ellipse.RenderTransform>
                </Ellipse>
            </DataTemplate>
        </ItemsControl.ItemTemplate>
    </ItemsControl>

relevant code:

  public double LargestCoordinate { get { return XList.Max(o => o.Distance); } }
}

class X {
  public Point Location { get; set; }
  public double LargestCoordinate { get { return Math.Max(Math.Abs(Location.X), Math.Abs(Location.Y)); } }
}
class Y {
  public List<X> ListOfX;
  public double LargestCoordinate { get { return XList.Max(o => o.Distance); } }
}

class X {
  public Point Location { get; set; }
  public double LargestCoordinate { get { return Math.Max(Math.Abs(Location.X), Math.Abs(Location.Y)); } }
