In A-mode, the z-axis represents what?

Explanation:
In A-mode there is only one line of data: depth is mapped along the horizontal axis based on the pulse’s travel time, and the height of each spike represents the echo amplitude. There isn’t a third dimension to plot; the z-axis simply isn’t defined in this mode. So, the z-axis represents nothing. This is why A-mode is a one-dimensional display of where boundaries are located along the depth line, with amplitude shown as spikes.
