NAME
gr_plot_short - plot short integer binary samples versus time using GNU Radio SYNOPSIS
gr_plot_short: [options] input_filenames DESCRIPTION
Takes a GNU Radio short integer 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] SEE ALSO
