WPF Graph - How to retrive horizontal & veritcal values when Zoom performed by GraphInteractionPalette

Hi,

I am using WPF graph and its  data changes continuously every 50ms.

I set XAxesRangeAdjuster  to FitExactly and I want to use GraphInteractionPallete to Zoom/ZoomHorizontal/ZoomVertical/ZoomIn/ZoomOut interactions.

When I  select area and want to ZoomHorizontal it resets because new data changes the range again.

I want to set range manually in ViewModel  and  select graph data manually  when Zoom event occurred.

How could we get selected area start&end positions?

Is there a event or something else when ZoomToFit or another button clicked?

Best Regards,

Thanks,

Thanks,
