Information oftentimes is graphically represented along the two dimensions of the vertical (V) and the horizontal (H).The graphic representation of an electromagnetic waveform, for example, plots amplitude (A), or signal strength, on the vertical axis, and frequency (f), or the periodic variation in value over time (t), on the horizontal axis. |
