Hi Milos, 
 
Thanks for your patience.  
 
We would like to let you know that in UWP that it has a framework level limitation to GetStream without adding it to the view. So, it is not possible in UWP to create the chart in fly as like in Android and iOS, since this is a framework level limitation, we must add it to the view in order to get it. 
 
Please refer the below link.

Is there another way to get SfChart as image bytes on UWP, without showing it to user?

Hi Milos, 
 
We regret to say that there is no way to get stream without adding it in view in UWP platform. We must add the view in UI tree.
