A graphical sink to display freq, spec, time, and const plots.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.
