This dialog is used to automatically scale the amplitude of a displayed spectrum.
The scaling is performed on the current waveform.
As such, this dialog will only work when the waveform is active and valid.
- Upper - sets the percentage of the vertical height that the highest point will reach
- Lower - sets the percentage of the vertical height that the lowest point will reach
- Round limits to next minor division - makes sure that the spectrum plot ends evenly at a minor division.
