Do not show phase - Hides the phase values on the plot.

Scale

The following options are available under Scale:

Linear

Plots the linear values.

Logarithmic

Plots the values in logarithmic scale.  With this scale, data points are spread out more, which makes it easier to view.

dB10

10 logarithmic of the participation value over the reference value.

dB20

20 logarithmic of the participation value over the reference value.  For acoustic responses, the reference pressure is 20E-12 MPa.

Weighting

Choose from Unweighted, A-, B-, C-, or D-weighting.  The weighting type is used to define equal loudness sound pressure levels.

Octave Band

Three menus allow you to customize the plot's octave band.

Select an octave band from the left-most drop-down menu:

Select Bar Plot or Line Curve as the octave plot type from the middle drop-down menu.

Select Sum, Integration, or Average as the Octave Magnitude from the right-most drop-down menu.

Unit

The Unit option allows you to display unit information in the axes labels.

Place a check mark in the Unit box to enable this feature; remove it to disable this feature.

The entity units are derived from unit sets for Time, Length and Force.  For example, the acceleration is m/s2 if Time is set to seconds (s), Length is set to meters (m), and Force is set to Newtons (N).
