Setting the Y Axis (Amplitude) Scale

Toggling the left axis scale between Linear, Log and dB will increase
or decrease the amplitude of displayed peaks allowing you to see
either the bigger picture or a more detailed view of the data. The
Linear scale is suitable for most cases. Log scaling (base 10) is more
useful for displaying vibration with both very large and very small
amplitudes.
