# Script that imports a FFF subghz file and draws a timing graph

# Example line:
# RAW_Data: 379 -798 807 -404 377 -798 805 -802 405 -396 393 -396 397 -394
# Where the numbers are the timings between changes from 0 to 1 and vice versa
# Positive numbers are rising edges, negative numbers are falling edges

# Setup dependencies
import matplotlib.pyplot as plt

# Setup arguments
import argparse
parser = argparse.ArgumentParser(description='Draw a subghz file')
parser.add_argument('-f', '--file', help='Subghz file to draw', required=True)

# Read in the file

    lines = f.readlines()

# Trim the lines

# Split the data into a list of individual timings

  timings.extend((int(x) for x in line.split()))

# Draw the graph

#Show the graph
