Most of them work off complex data produced by digital waveforms. - - -** gr_plot_float.py: -Takes a GNU Radio floating point binary file and displays the samples versus time. You can set the block size to specify how many points to read in at a time and the start position in the file. - -By default, the system assumes a sample rate of 1, so in time, each sample is plotted versus the sample number.
