For show at specified points only in Plot Details’s Label tab, Origin support 0 to indicate last point in layer. But for 1st point, index is 1, it will always indicate the 1st point in plot. Origin2024 will use -1 to indicate 1st point in layer, so the plot label will show even if axis scale is changed.
