Hi Vladimir,
It is by design that SfDiagram WinRT updates the Layout in its loaded event
(i.e. Data for Layout are assigned before that). After analyzing your sample,
we came to know that Data for Layout is assigned in Page loaded event (after
Diagram is loaded). So, the Layout does not get refreshed. In order to solve
this problem, Layout can be updated manually after data assigned.
Please let us know if you have any concerns
