Remarks

 

Obtains the value of one of the settings for the given wave range added to the waveform analyzer. Value of single settings can be modified through the GraphicItemWaveRangeParamsSetEx method.

This method is an alternative to the GraphicItemWaveRangeParamsGet method and is provided with the purpose of allowing single settings modifications when dealing with languages like JavaScript where data structures are not easy to implement.
