graph it.py

# This will make a graph in the format that you specify
# Select a region around the origin and then click filter
# The height of the selection box does not matter but the depth and length does
# If you are going to write your own equation then you will need to replace x with k and z with m
# Sample rate is the number of calculations that it will do per block in one direction
# If you are putting in an exponential graph then increase this number
