This example shows a use case for 3D Box Series as a 3D spectrogram
Spectrogram is a visual representation of the spectrum of frequencies. Spectrograms can be used to visualize any wave form. Most often spectrograms are used to display audio signals.
The spectrogram shows frequency on one axis (X Axis) and time on the other (Z Axis). The amplitude of the frequency is displayed both by the Y coordinate as well as the dynamically applied color.
