I noticed that there are problems when I try to add data series, create renderable series, or annotations while the view that hosts the scichartgroup and/or scichartsurface(s) is/are not yet initialized/rendered. Could this be a bug? After all it should not matter when the view is rendered; when it is rendered its elements bind to the matching properties of its viewmodel, no?
This poses problems for me because I am forced to take the viewmodel-first approach. So, when I create an instance of my viewmodel and then invoke methods in the viewmodel that add data series and render such I am experiencing errors (the rendered series is not displayed on the chart, though annotations strangely are).
I identified the problem to be 2-fold, one is that I have to create renderable series on the UI thread (solved that, no issue) but my other big problem is that the view is actually not instantiated/rendered unless the view is in focus/visible which is not the case during runtime when data series are added via viewmodel.
How can I solve this problem?
