PSA has max 8192 display points, namely buckets, but its screen only has 600 pixels, what's the tactic to display 8192 points within 600 pixels? Is there any possibility missing some important display points?

Thanks! "
When we draw the trace on the display, it is scaled so that first point is at the left edge of the graph and the last point is on the right edge of the graph. The result is that multiple buckets map to the same 'X' point on the graph. Each bucket's 'Y' value is drawn at that 'X' point. So, you end up with multiple buckets on each vertical line of the graph.
No data is lost in this process although it can be hard to resolve individual points in the line. The marker will display every point though.
If one "x" point in the screen can represent multiple buckets and the marker can display every bucket, how the marker distinguish each bucket for the same "x" point in screen? Does the marker goes through all the buckets in the screen point and displays each bucket Y value one by one?

Yes, that is exactly how it works. You will see the marker jump up and down to the next Y bucket value while holding the same X position
