Description Makes the y-axis of all waveforms the same as the current (selected) waveform.
  Notice how the hotkey combination works (x Y y) to expand and link scales in both x and y axis.
Hot Key  y
Script *&y Match all y-axis scales to that of the current trace.
constants.max = maxscale(current)
constants.min = minscale(current)
