This is a QT-based graphical sink that takes in byte streams or floating point streams and plots a time_raster (spectrogram) plot.

Input stream: This expects a bit stream (0, 1 in the LSB of a byte). It will display packed bytes but the display will have to be autoscaled.

This sink can plot messages that contain either uniform vectors of float 32 values (pmt::is_f32vector) or PDUs where the data is a uniform vector of float 32 values.

Parameters

(R): Run-time adjustable
