Tag: CompositeAnnotationViewModel

Hello,

I have two questions regarding implementing annotations in MVVM:

I’m currently using the MeasureXYAnnotation as demonstrated in an example, and it works well in the code-behind using the CompositeAnnotation class. However, when trying to implement this in MVVM with CompositeAnnotationViewModel, I’ve noticed that the Update method is missing. This omission prevents me from dynamically updating the measures. Is there a way to achieve the same dynamic behavior in MVVM as in code-behind? If so, could you please guide me on how to do it?

My second question is about the BrushAnnotationViewModel, which I’ve seen used in the trade annotation example. Is this ViewModel exclusive to trade charts, or can it be applied to XYCharts as well?

Thank you,
Best Regards
