What is the unit of the X axis?
The default minRange for the x axis is five times the smallest interval between any of the data points. On a logarithmic axis, the unit for the minimum range is the power. So a minRange of 1 means that the axis can be zoomed to 10-100, 100-1000, 1000-10000 etc.
What is the Y-axis on a soundwave?
The amplitude (y-)axis of the graphs of sound represents the amount of air compression (above zero) or rarefaction (below zero) caused by a moving object, like vocal chords. Note that zero is the "rest" position, or pressure equilibrium (silence).
What unit should be used to label the Y-axis?
Choosing Scale for the Y-Axis
The scale could go from zero to 15, and the y-axis title would be "Growth (centimeters)." If you didn't add the unit of measure, people wouldn't know if you were talking about growth in millimeters, inches or miles.
