This method displays the waveform of the signal. No parameter is computed.
The amplitude range for the waveform display. The amplitude can be specified as a percent of the full attenuation amplitude (check the in % box), or in absolute terms, where
1 is full attenuation.
If checked, the best scale range is automatically calculated (and the range parameter is ignored).
If checked, the envelope of the waveform is plotted. If left unchecked, the waveform function is filled in.
