42
* This is a QT-based graphical sink the takes set of a complex
43
* streams and plots a waterfall (spectrogram) plot.
44
*
45
* Note that unlike the other qtgui sinks, this one does not
46
* support multiple input streams. We have yet to figure out a
47
* good way to display multiple, independent signals on this kind
48
* of a plot. If there are any suggestions or examples of this, we
49
* would love to see them. Otherwise, to display multiple signals
50
* here, it's probably best to sum the signals together and
51
* connect that here.
