Detailed Description

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.

fc	center frequency of signal (use for x-axis labels)
bw	bandwidth of signal (used to set x-axis labels)
name	title for the plot
plotfreq	Toggle frequency plot on/off
plotwaterfall	Toggle waterfall plot on/off
plottime	Toggle time plot on/off
plotconst	Toggle constellation plot on/off
parent	a QWidget parent object, if any
