GR_PLOT(1) User Commands GR_PLOT(1)

gr_plot - display time series of samples from a file

Show data captured using the gnuradio file sink.

usage: gr_plot [-h]

[-d {complex64,float32,uint32,int32,uint16,int16,uint8,int8}] [-B BLOCK] [-s START] [-R SAMPLE_RATE] FILE [FILE ...]

Takes a GNU Radio 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.
