Detailed Description

A graphical sink to display multiple signals on a waterfall (spectrogram) plot.

This is a QT-based graphical sink the takes set of a complex streams and plots a waterfall (spectrogram) plot.

Note that unlike the other qtgui sinks, this one does not support multiple input streams. We have yet to figure out a good way to display multiple, independent signals on this kind of a plot. If there are any suggestions or examples of this, we would love to see them. Otherwise, to display multiple signals here, it's probably best to sum the signals together and connect that here.
