Markers disappear when panning the XY view

I've added SeriesEventMarkers and ChartEventMarkers in the chart. They work correctly, but when I pan the view so that the markers go under X axis minimum, and then pan back to original position, I don't see the markers anymore.

How to fix this?

LightningChart has automatic destruction of out-scrolled data and markers. The chart deletes the marker in this case, when it goes under X axis minimum.
To fix that, set ViewXY.DropOldEventMarkers = False.
In v.5.1 and above, DropOldEventMarkers = True by default. In older versions, it is False by default.
