[Data binding issue? Point is not updated.]

Hello,

 

I have a pie chart bound to a observable collection of some data objects. Chart Series is bound to a property of this data object. When I add new object into collection chart gets updated, but when I change value of the property that is bound to the series - it is not reflected in the chart. Is it by design or just some oversight in the current version? Or there is another way to get the result I want?

Thank you!

 

Here is an example:

public class Venue : DependencyObject

{

  public Venue()   {   } 

  public static readonly DependencyProperty NameProperty =   DependencyProperty.Register("Name", typeof(string), typeof(Venue),   new FrameworkPropertyMetadata("", FrameworkPropertyMetadataOptions.AffectsRender));   public string Name   {   get { return (string)GetValue(NameProperty); }   set { SetValue(NameProperty, value); }   }   public static readonly DependencyProperty PercentProperty =   DependencyProperty.Register("Percent", typeof(double), typeof(Venue),   new FrameworkPropertyMetadata(0.0, FrameworkPropertyMetadataOptions.AffectsRender)));   public double Percent   {   get { return (double)GetValue(PercentProperty); }   set { SetValue(PercentProperty, value); }   }

} 

 

<Window.Resources> <local:Venues x:Key="selectedVenues"/>

  </Window.Resources>

<Grid>

<ChartFX:Chart x:Name="distChart" Style="{DynamicResource chartStyle}" Background="LightGray" Gallery="Pie" ItemsSource="{Binding Source={StaticResource selectedVenues}}">   <ChartFX:SeriesAttributes BindingPath="Percent" >   </ChartFX:SeriesAttributes>   </ChartFX:Chart> </Grid>
