Hello Luo,
From the code that you have provided (chart.Series) it seems that you are talking about the RadChartView and not the RadChart control. This is why I have changed the product of this thread. Let me know if I have made a mistake.
Now, onto your question. The chart not getting updated is expected because double[] is not an observable collection. You will either need to reset the ItemsSource every time you need the chart to update or use an observable collection instead:
