* \brief A graphical sink to display freq, spec, time, and const plots.
* \ingroup instrumentation_blk
* \ingroup qtgui_blk
*
* \details
* This is a QT-based graphical sink the takes a complex stream and
* plots it. The default action is to plot the signal as a PSD (FFT),
* spectrogram (waterfall), time domain I&Q, and constellation (I
* vs. Q) plots. The plots may be turned off by setting the
* appropriate boolean value in the constructor to False.
*
* 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.
*
* - 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.
