GR_PLOT_FLOAT(1)						   User Commands						  GR_PLOT_FLOAT(1)

NAME

       gr_plot_float - plot floating point binary date using GNU Radio

SYNOPSIS

       gr_plot_float: [options] input_filenames

DESCRIPTION

       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.  To set a true time axis, set the sample rate (-R or --sample-rate) to the sample rate used when capturing the
       samples.

OPTIONS

       -h, --help
	      show this help message and exit

       -B BLOCK, --block=BLOCK
	      Specify the block size [default=1000]

       -s START, --start=START
	      Specify where to start in the file [default=0]

       -R SAMPLE_RATE, --sample-rate=SAMPLE_RATE
	      Set the sampler rate of the data [default=1.0]
