Hi Infragistics-people,
I'm using a XamDataChart with ValueMemberPath. When i change the value and send a property changed event the chart does not update the data point.
Is it supposed to work?
Yes => I'll send you demo project
No => Can i place a feature request for this issue?

Hi,
You mentioned that you are changing the value. I assume that you are changing a value in the collection that is bound to the control. Double check that your viewmodel implements iPropertyChanged.
It would probably be a god idea for you to zip up your sample so I can see your demo project.
Well, i'm changing the value of the property where the value for the y-axis is provided. Yes, it implements INotifyPropertyChanged.
But as i see in the debugger there is listener added on the PropertyChanged event. That's why i assumed the chart control does not support propertychange on data points.
I send you an example attached. There's a bit more included because it's my test project for the chart control. Click on the "ChangeValue" button to change the view models value. The chart does not update. But it updates when changing the ValueMemberPath so property change works in general.
ps: Thank you for the quick answer.

Let me know if I can provide any further assistance.
