I want to add a dynamic micro chart to my application but it doesn't work. After a call from a method a value gets added and it makes a completely new micro chart for my chart to have the new values, but the change isn't visible in the app. So the old Values stayed and there is no new one. Thanks for helping me.

WeightList = new List<float>();
        WeightList.Add(0);
        WeightList.Add((float)74.3);
        entries = new ChartEntry[30];
        SyncArray();

private void SyncArray()
    {
        if (WeightList.Count != entries.Length)
        {
            entries = new ChartEntry[WeightList.Count];
        }

        for (int i = 0; i <= WeightList.Count - 1; i  )
        {
            if (i == WeightList.Count - 1 || i == 0)
            {
                entries[i] = new ChartEntry(WeightList[i]) { Label = ""   i, ValueLabel = ""   WeightList[i] };
            }
            else
            {
                entries[i] = new ChartEntry(WeightList[i]) { Label = ""   i };
            }
        }
        chart = new LineChart() { Entries = entries, BackgroundColor = SKColors.Transparent };
        Chart = chart;
    }

public LineChart Chart
    {
        get => chart;
        set => SetProperty(ref chart, value);
    }

public float Weight
    {
        get => weight;
        set
        {
            weight = value;
            WeightList.Add(weight);
            SyncArray();
        }
    }

private void SyncArray()
{
    if (WeightList.Count != entries.Length)
    {
        entries = new ChartEntry[WeightList.Count];
    }

    for (int i = 0; i <= WeightList.Count - 1; i  )
    {
        if (i == WeightList.Count - 1 || i == 0)
        {
            entries[i] = new ChartEntry(WeightList[i]) { Label = ""   i, ValueLabel = ""   WeightList[i] };
        }
        else
        {
            entries[i] = new ChartEntry(WeightList[i]) { Label = ""   i };
        }
    }
    Chart = new LineChart() { Entries = entries, BackgroundColor = SKColors.Transparent };
