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)

Number of cols to plot

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)
