Hello
Thank you for answer. I updated C1 to this version but it didn’t fix the problem, I still get same exception.
Also labels added through PointLabelTemplate don’t became collapsed/visible synchronously with DataSeries and don’t have same ZIndex as DataSeries they attached to. If now is should be that way, how can I make them work as before? Since they are added as DataTemplate it is hard to change any of their property.
