X-Scaling
Defines the scaling method for the frequency (x-)axis of the spectrum display.
"Linear"
Linear scaling
"Logarithmic"
Logarithmic scaling
Note that in this mode, not all possible amplitude values for a specific
frequency may occur. Each result is indicated by a bright, colored
trace point.
The DC amplitude (at 0 Hz) is not displayed, as lg(0) is not defined.
