QT GUI Time Raster Sink

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


 * Name
 * Title for the plot


 * Sample Rate

 * Num. Rows (R)
 * Number of rows to plot


 * Num. Cols (R)

 * Grid


 * Int. min


 * Int. max


 * Multiplier (R)
 * Vector of floats as a scaling multiplier for each input stream


 * Offset (R)
 * Vector of floats as an offset for each input stream


 * Number of Inputs
 * Number of streams connected


 * Update Period (R)
