我想在修改列表中的元素后更新视图。目前，当我修改列表中的项目时，系列会正确更新，但视图不会更新，或者只是部分更新。我应该提到的是，被修改的属性是颜色，如果调整我的窗口大小，视图会正确更新。
我的对象：

`public class cDay : ObservableObject
 {
    public cDay()
    {
        byte[] abyColors = cColorConverter.HexToBytes("#A5A5A5");
        oColor = new SolidColorPaint(new SKColor(abyColors[0], abyColors[1], abyColors[2]));
    }
    private SolidColorPaint color;
    public SolidColorPaint oColor 
    {
        get => color;
        set
        {
            color = value;
            OnPropertyChanged();
        }
    }
    private double value;
    public double Value
    {
        get => value;
        set
        {
            this.value = value;
            OnPropertyChanged();
        }
    }

    private string label;
    public string Label
    {
        get => label;
        set
        {
            label = value;
            OnPropertyChanged();
        }
    }
}`
