Waves
Waves are vectors (arrays) in which data is stored. Point number counts from 0 (i.e., MyWave[0] is the first element of the wave).
Waves have inherent x values that are by default equal to the point number. If you display a wave, it is automatically plotted versus the x value (0, 1, 2, etc.). It is possible to change the inherent wave scaling (see setScale), or you can plot a y-wave versus an x-wave.
