Hi.
We're trying to upgrade from the Q1 library to the Q2 SP1 libraries to get rid of nasty "Layout cycle exception" in our chart views.
However, when referencing the new assemblies, the charts now show "No Data Series" !
The view model still populates the data as before.
It seems like there was a breaking change in the API but I'm not sure how to pinpoint what the issue is.
Any help would be much appreciated.
Thanks
Edit:
Here is the xaml markup:
