Binding ItemsSource to LineSeries

[kl]

I'm having difficulty to display the data on the chart where the data are changed dynamically.
The graph would not populate the data according to the changes made.
Below is the snippet of the code, kindly guide if i did anything wrong.

p/s: The GetData will get the changes of data to be plot on the graph

XAML:

<chartView:LineSeries Stroke="Red" StrokeThickness="2" ItemsSource="{Binding ListValue}" ValueBinding="Value" CategoryBinding="Category">

ViewModel.cs

private List<SampleClass> tempList;
public List<SampleClass> ListValue
{
     :
     :
}
public void GetData(string tempValue)
{
       SampleClass item = new SampleClass ();
       item.Value= tempValue;
       item.Category = m_counter++;
       tempList.Add(item);

       ListValue= tempList;
}

Hi,

The problem is that the List<> class does not notify the chart that its data has changed. Changing the ItemsSource from List<> to ObservableCollection<> should solve the problem.
