* \brief A graphical sink to display multiple signals on a
* waterfall (spectrogram) plot.
* \ingroup instrumentation_blk
* \ingroup qtgui_blk
*
* \details
* 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.
*
* The sink supports plotting streaming complex data or
* messages. The message port is named "in". The two modes cannot
* be used simultaneously, and \p nconnections should be set to 0
* when using the message mode. GRC handles this issue by
* providing the "Complex Message" type that removes the streaming
* port(s).
*
* This sink can plot messages that contain either uniform vectors
* of complex 32 values (pmt::is_c32vector) or PDUs where the data
* is a uniform vector of complex 32 values.
*
* Message Ports:
*
* - freq (input):
* Receives a PMT pair: (intern("freq"), double(frequency)).
* This is used to retune the center frequency of the
* display's x-axis.
*
* - bw (input):
* Receives a PMT pair: (intern("bw"), double(bandwidth)).
* This is used to programmatically change the bandwidth of
* of the display's x-axis.
*
* - freq (output):
* Produces a PMT pair with (intern("freq"), double(frequency)).
* When a user double-clicks on the display, the block
* produces and emits a message containing the frequency of
* where on the x-axis the user clicked. This value can be
* used by other blocks to update their frequency setting.
*
* To perform click-to-tune behavior, this output 'freq'
* port can be redirected to this block's input 'freq' port
* to catch the message and update the center frequency of
* the display.
