Hi Komatora,We can update the existing data points value dynamically by
setting the ListenPropertyChange property of ChartSeries to true
and the ChartDataModel should implement the INotifyPropertyChanged as per in the below code example,

<chart:CandleSeries ItemsSource="{Binding StockPriceDetails}"
                      High="High" Low="Low" 
                      Close="Close" Open="Open" 
                      ListenPropertyChange="True"
                    
   XBindingPath="Date"/>

public  class ChartDataModel : INotifyPropertyChanged
  {
      private double high;
   
      public double High
      {
          get { return high; }
          set
          {
              if (value != high)
              {
                  high = value;
                 
  RaisePropertyChanged(nameof(High));
              }
          }
      }
      ….
     
      public event PropertyChangedEventHandler
  PropertyChanged;

void RaisePropertyChanged(string name)
      {
          PropertyChanged?.Invoke(this, new
  PropertyChangedEventArgs(name));
      }
  }
