In a Doppler spectrum, the brightness of the dot represents the amplitude along which axis?

Explanation:
Brightness on a Doppler spectrum shows how strong the signal is at a given point. In many 3D representations, two axes lay out velocity (Doppler shift) and time, while the third dimension carries the amplitude information. That third dimension is the Z axis, and the brightness of each dot maps to that amplitude along Z. So a brighter dot means a larger Doppler signal strength at that velocity and time. The velocity and time positions come from the other two axes, which is why brightness isn’t about them.
