* \details
45
* This is a QT-based graphical sink the takes a complex stream and
46
* plots it. The default action is to plot the signal as a PSD (FFT),
47
* spectrogram (waterfall), time domain I&Q, and constellation (I
48
* vs. Q) plots. The plots may be turned off by setting the
49
* appropriate boolean value in the constructor to False.
50
*
51
* Message Ports:
52
*
53
* - freq (input):
54
* Receives a PMT pair: (intern("freq"), double(frequency).
55
* This is used to retune the center frequency of the
56
* display's x-axis.
57
*
58
* - freq (output):
59
* Produces a PMT pair with (intern("freq"), double(frequency).
60
* When a user double-clicks on the display, the block
61
* produces and emits a message containing the frequency of
62
* where on the x-axis the user clicked. This value can be
63
* used by other blocks to update their frequency setting.
64
*
65
* To perform click-to-tune behavior, this output 'freq'
66
* port can be redirected to this block's input 'freq' port
67
* to catch the message and update the center frequency of
68
* the display.
