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
 * Sample rate of signal


 * 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)


 * GUI Hint
 * See GUI Hint for info about how to organize multiple QT GUIs


 * Axis Labels


 * Line Label


 * Line Color


 * Line Alpha

Example Flowgraph
Insert description of flowgraph here, then show a screenshot of the flowgraph and the output if there is an interesting GUI. Currently we have no standard method of uploading the actual flowgraph to the wiki or git repo, unfortunately. The plan is to have an example flowgraph showing how the block might be used, for every block, and the flowgraphs will live in the git repo.
