+ * \brief A graphical sink to display freq, spec, time, and const plots.
+ * \ingroup qtgui_blk
+ *
+ * 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.
